Description

A new type of hand restraint device and restraint system with monitoring and alarm function

technical field

The present invention relates to the field of medical intelligent wearable devices, in particular to a novel anti-mistouch hand restraint device with monitoring and alarm function, which is mainly used for critically ill patients and critically ill patients with vague or unconscious involuntary activities.

Background technique

During the treatment of infectious diseases, a large number of patients need to be isolated and treated. Among them, severe or critically ill patients need intubation treatment to reduce mortality. Most of the patients undergoing intubation treatment are in a state of confusion, and most of the movements of their limbs are involuntary activities. Patients undergoing intubation therapy are likely to touch the intubation device unconsciously or vaguely, which may easily lead to the failure of intubation therapy and affect their life safety. In addition, in the intensive care department, in order to save lives effectively, medical personnel also need to wear a lot of protective equipment. On the one hand, medical personnel cannot monitor the physical activities of critically ill patients in real time. Therefore, how to effectively monitor and effectively control the physical activity of critically ill patients or critically ill patients is an urgent problem to be solved by the Department of Critical Care Medicine.

For example, the Chinese Patent Publication No. CN110801329A discloses a novel anti-extraction tube hand restraint device with monitoring and alarm function. The hand restraint device includes a glove body, a controller and an air pump. The controller is installed in the air pump, and a single-chip microcomputer is arranged in the controller. The end position of the glove body is provided with a wrist portion, and a fixed belt buckle is arranged on the wrist portion. The main airbag is arranged in the position and in the wrist, and the main airbag on the glove body and the wrist is equipped with an inflation interface. The hand restraint device sets the air bag at the palm position, and the acceleration sensor detects the movement range of the patient's hand and limbs. When the movement range is too large, the single-chip microcomputer controls the opening of the air pump to inflate the air bag, inflating the air bag, thereby limiting the patient's movement. The bending range of the fingers can prevent the patient from scratching and restrain the patient.

The device is suitable for patients who can get out of bed voluntarily, and is used to prevent their active extubation behavior due to psychological factors. The device is used to limit the movement of fingers to prevent the patient from actively grasping and extubating the cannula. Therefore, the device also has a defect: even if the patient wears the device, the cannula may still be touched.

In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, because the inventor has studied a large number of documents and patents when making the present invention, but the space limit does not list all the details and contents in detail, but this is by no means The present invention does not possess the features of the prior art, on the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art.

SUMMARY OF THE INVENTION

In the prior art, most of the patients' hands are fixed and restrained in a fixed manner. Restricting the patient's physical activity can be restrained by binding the patient. However, this simple medical treatment involves the dignity of the patient on the one hand, and causes festering, pressure ulcers, etc. on the patient's bindings on the other hand. In addition, patients wearing the binding system are forced to maintain a certain posture for a long time, which has a problem of comfort, and it is difficult to wear them for a long time.

In view of the deficiencies of the prior art, the present invention provides a novel anti-mistouch hand restraint device with monitoring and alarm function. The apparatus includes: a palm restraint sleeve, an elbow restraint sleeve, a palm motion monitor, an elbow motion monitor and a data processor. A palm restraint sleeve, which is worn on the patient's hand and wrist, and can mainly be used to limit at least one movement dimension of the patient's palm and wrist; an elbow restraint sleeve, which is worn on the patient's elbow It is mainly used to place the patient's arm (big arm and forearm) in a comfortable state or a state that is conducive to the patient's recovery; a palm motion monitor, which is arranged on the palm restraint sleeve, is used to monitor the The patient's palm and wrist movement to obtain palm movement parameters and wrist movement parameters; an elbow movement monitor, which is arranged on the elbow restraint sleeve, is used to monitor the patient's upper arm and lower arm movement , to obtain the motion parameters of the upper arm and the forearm; and a data processor, which is respectively connected to the palm motion monitor and the elbow motion monitor for data connection. The above-mentioned palm motion monitor and elbow motion monitor can be a micro acceleration sensor, an angle sensor, a displacement sensor, etc., and the data processor can calculate the patient's motion posture by using the parameters collected by the data processor.

In actual medical practice, it is a small probability event that a patient's hand touches a contact medical device such as a cannula. First of all, most of the patients are in the lying position, most of them are in a state of natural relaxation (especially the patients with blurred consciousness or unconscious patients), and their arms are pressed against the bed; secondly, the patient's hands should touch In order to touch the intubation, certain conditions need to be met, namely: first, raise the upper arm and forearm, and have a certain posture, and secondly, the hand and wrist also need a certain posture, so that the conditions for touching the intubation can be achieved.

Therefore, the hand restraint device provided by the present invention is not a fixed "restraint" device in the true sense, but a movable "restraint" device. The purpose of the restraint device is: for an unconscious or vaguely conscious patient, it can allow the patient's hand to move unconsciously, but this movement cannot touch any contact medical device ( such as intubation). The main advantages of this are: 1. Allowing unconscious movement is helpful for the patient's recovery. Through the data curve data fed back by the data processor, the doctor can clearly understand the patient's unconscious movement, which is helpful for the doctor to understand the patient's vital signs; 2. Respect the patient: some critically ill patients also indicate that their life is about to end when they undergo intubation treatment. By allowing them to exercise to retain their dignity at the moment of life, giving patients psychological comfort may also prolong their life or may also allow their patients. 3. The movement of the limbs is rarely likely to cause the patient to touch the contact medical instrument. Therefore, it is absolutely unnecessary to not allow the patient's hand movement, that is, it is not necessary to collect movement data all the time. To this end, the present invention further provides the following technical solution: in the case that the active posture corresponding to the upper arm motion parameter and the forearm motion parameter triggers an early warning condition, the palm motion monitor is located in the palm The constraining sleeve collects the palm motion parameters and the wrist motion parameters under the condition that the movement of the hand and the wrist is not restricted; wherein, in the activity posture corresponding to the palm motion parameters and the wrist motion parameters When an adjustment condition is triggered, the adjustment components in the palm restraint sleeve and/or the elbow restraint sleeve limit at least one movement dimension of the patient's hand and wrist in response to the data processor adjustment signal activated in a manner to prevent the patient from touching the medical contact device. That is, for unconscious or vaguely conscious patients, the hand movement of the arm in the warning posture state is restricted to a dangerous posture, and the hand is restricted to prevent it from touching medical instruments such as intubation.

According to a preferred embodiment, the elbow restraint sleeve can restrain the palm in a manner that the elbow drives the palm when the active posture of the palm triggers the adjustment condition The way to enter the forbidden area is restored to the normal state.

According to a preferred embodiment, the hand restraint is used to restrain at least one of the palm and/or the wrist in response to the adjustment signal before the elbow restraint activates the elbow posture adjustment Motion dimensions for emergency avoidance of contact equipment. Because the patient's unconscious movements may be too violent and disorderly, in these disorderly work, the palm or wrist may not have touched the adjustment conditions at one moment, but may touch the contact device at the next moment. The elbow restraint has not had time to adjust the movable posture of the arm, therefore, the palm restraint needs to be used to avoid the medical contact device urgently.

According to a preferred embodiment, the elbow restraint includes a support bladder plate extendable from its body toward the wrist, the support bladder plate being configured such that the support bladder plate, when inflated, is capable of compressing any The lower arm gradually returns to substantially straight line with the upper arm; the support bladder plate can flex in its uninflated condition to allow free movement of the elbow.

According to a preferred embodiment, the data processor is capable of activating a video monitor based on increments of the palm motion parameter and the wrist motion parameter monitored by the palm motion monitor, thereby constraining the The device is capable of initiating an abnormal posture determination mode by means of the video monitor.

According to a preferred embodiment, both the palm restraint cover and the elbow restraint are provided with a reset force sensor, and the reset force sensor collects data collected on the palm restraint and the elbow restraint to restrain the hand The data processor is capable of adjusting the rate of reduction of adjustment elements of the palm and elbow restraint sleeves based on the return force collected with at least one dimension of motion of the body part.

According to a preferred embodiment, the palm motion monitor, the elbow motion monitor and the reset force sensor are all wirelessly connected to the data processor.

According to a preferred embodiment, the data processor is communicatively connected to an alarm terminal in response to the adjustment signal, and the alarm terminal limits at least one movement dimension of the patient's hand and wrist in the hand restraint sleeve It can be presented in at least one prompt mode of sound, light, text, picture, and video.

According to a preferred embodiment, the present invention discloses a hand restraint system, comprising: a palm movement monitor, which is arranged on the palm restraint sleeve, and is used to monitor the movement of the patient's palm and wrist, so as to Obtaining palm motion parameters and wrist motion parameters, an elbow motion monitor, which is arranged on the elbow restraint sleeve, is used to monitor the motion of the patient's upper arm and forearm, and obtains the motion parameters of the upper arm and the forearm, and a data processor, which are respectively connected with the palm motion monitor and the elbow motion monitor in data connection, in the case that the active posture corresponding to the forearm motion parameter and the forearm motion parameter triggers an early warning condition , the palm motion monitor collects the hand motion parameters and the wrist motion parameters under the condition that the palm restraint sleeve does not restrict the movement of the hand and the wrist; wherein, in the palm When the motion parameters and the active posture corresponding to the wrist motion parameters trigger the adjustment condition, the adjustment components in the palm restraint sleeve and the elbow motion monitor respond to the adjustment signal of the data processor according to the limit. At least one dimension of motion of the patient's hand is activated to prevent the patient from reaching a medical contact device.

According to a preferred embodiment, the data processor is communicatively connected to an alarm terminal in response to the adjustment signal, and the alarm terminal limits at least one movement dimension of the patient's hand and wrist in the hand restraint sleeve It can be presented in at least one prompt mode of sound, light, text, picture, and video.

Example 1

The present embodiment discloses a novel hand restraint device with monitoring and alarm function for preventing false touches. The hand restraint device is, in particular, a restraint device that limits the range of motion of the hand of a patient who is confused or unconscious. The restraint device includes a palm restraint sleeve 100, an elbow restraint sleeve 200, a palm motion monitor 300, and an elbow motion monitor 400.

The palm restraint sleeve 100, which is worn on the palm and wrist of a patient, is used to limit the range of motion of the palm and wrist.

An elbow restraint 200 is worn on the patient's elbow and is capable of restoring the upper and lower arms to a normal posture.

The palm movement monitor 300, which is arranged on the hand restraint sleeve 100, is used to monitor the movement of the patient's hand and wrist, so as to obtain the palm movement parameters and the wrist movement parameters. The palm motion monitor 300 may be at least one of an acceleration sensor, a displacement sensor, and an angle sensor.

The elbow motion monitor 400, which is arranged on the elbow restraint sleeve 200, is used to monitor the motion of the patient's upper arm and forearm, and obtain the parameters of the motion of the upper arm and the forearm. The elbow motion monitor 400 may be at least one of an acceleration sensor, a displacement sensor, and an angle sensor.

The data processor 500 is respectively connected with the palm movement monitor 300 and the elbow movement monitor 400 in data connection. The data processor 500 may include a CPU, GPU, FPGA and other servers with data operation functions.

According to clinical observations, the patient needs to do at least the following actions to reach the cannula: the arm is flexed and the palm is in a specific position. Therefore, based on clinical observations and data studies, the present invention can allow the patient's hand to move in a non-specific position, but respond to monitoring when the hand enters a specific position, so that the patient's hand can move out of the specific position. This method can effectively reduce the occurrence of pressure ulcers and ulcers in patients, and patients can use the device with dignity during treatment.

First of all, the cavity conditions for the patient to touch the cannula are: the upper arm and forearm have a certain active posture. That is: the active posture of the upper arm and the lower arm needs to trigger the warning condition. Early warning conditions can be related to different medical contact device positions, patient arm lengths, and arm lengths of the upper and lower arms. For example, medical contact devices may include: trachea, gastric tube, and urinary tube. The doctor inputs parameters such as the patient's arm length, upper arm, forearm length, intubation position, and intubation in vitro length into the data processor 500, and the data processor 500 pre-generates an early warning condition space attitude range. The generation model of the warning condition can be generated after deep learning based on several clinical data. The warning condition may also be predefined by the physician. The pre-warning condition is a spatial attitude range, and as long as the patient's active posture falls within the spatial posture range, the pre-warning condition will be triggered. Moreover, when the active posture of the forearm and the forearm triggers the warning condition, the patient may not necessarily touch the medical contact device. At this time, the probability of only touching the medical contact device increases. Movement of the palm and wrist is monitored. To this end, the data processor 500 is configured to: send a collection signal to the palm motion monitor 300 to collect the hand motion parameters and the wrist motion when the active posture corresponding to the upper arm motion parameter and the forearm motion parameter triggers an early warning condition Parameters, at this time, the palm restraint sleeve 100 does not restrict the movement of the palm and wrist. That is, in the case where the active posture corresponding to the palm motion parameter and the wrist motion parameter triggers the adjustment condition, the adjustment components of the palm restraint sleeve 100 and/or the elbow restraint sleeve 200 respond to the adjustment signal of the data processor 500 according to the limit At least one dimension of movement of the hand is activated to prevent the patient from touching the medical contact device. The adjustment condition is also preset, which belongs to a narrower scope of activity space within the warning condition. For example, the adjustment condition may be that the linear distance between the palm and the cannula is 5 cm. The pre-warning condition is that the straight-line distance between the palm and the cannula is 15 cm. According to at least one movement dimension of the restricted hand, it may be: restricting the linear movement of the palm from continuing to approach the cannula, or restricting the angle of the wrist continuing to deflect toward the cannula, and the like.

Preferably, the hand restraint sleeve 100 is responsive to the adjustment signal before the elbow restraint sleeve 200 does not initiate an elbow posture adjustment for limiting at least one dimension of motion of the palm and/or wrist for emergency avoidance of the contact instrument. The adjustment signal of the data processor 500 is a signal for preventing the hand, especially the palm, from touching or grasping the cannula. Due to the physiological structure and physiological response of the human body, the palm is more likely to touch or grasp the cannula than the arm, so emergency restraint on the hand is particularly important. For example, when the patient's limb movements respond strongly, especially when the arm enters the spatial range corresponding to the warning condition, the data processor 500 extracts strong feature values based on the hand movement parameters and wrist movement parameters collected by the palm movement monitor. Parameters such as acceleration, displacement amplitude, etc., to determine whether to limit at least one movement dimension of the palm and/or wrist to avoid contact instruments urgently. Based on the concept of space, the motion dimension is three-dimensional with 6 degrees of freedom, i.e. the palm and/or wrist can be prevented from linear motion, rotation, etc.

Preferably, elbow restraint 200 includes a support bladder plate 900 that can extend from its body 200e toward the wrist. The body 200e is also configured to be inflatable at the same time. The support bladder panel 900 is configured as an inflatable bladder panel. It is worn on the patient's forearm in a semi-open style. The support bladder plate 900 is configured such that the support bladder plate 900, when inflated, is able to gradually restore the forearm to substantially straight line with the forearm. The support bladder plate 900 can flex when it is not inflated to allow free movement of the elbow. Thus, the elbow can move within a certain range of motion relative to the forearm based on the amount of inflation of the support bladder plate 900. On the contrary, the elbow restraint sleeve 200 can be restored to a normal state in a way that the elbow can lead the palm to restrict the palm from entering the forbidden area when the support bag 900 is gradually inflated. Preferably, the support bladder plate 900 and the body 200e are automatically inflated based on an external inflation device when the active posture of the palm triggers the adjustment condition. Preferably, compared with the adjustment condition of the hand restraint sleeve 100, the elbow restraint sleeve 200 is triggered when the patient's palm or motion is not strong but stays in the spatial range corresponding to the adjustment condition for a long time, so as to prevent The patient's hand is gradually restored to a normal state based on the elbow restraint 200 .

Preferably, the data processor 500 can activate the video monitor 700 based on the increments of the palm motion parameters and the wrist motion parameters monitored by the palm motion monitor 300. Video monitor 700 is an auxiliary monitoring device. The increments of palm motion parameters and wrist motion parameters represent the intensity of palm and wrist motion. When the video monitor 700 is activated, the medical staff can determine the abnormal posture of the patient based on the image data, which is particularly important for the prevention and control of infectious diseases. Because in the infectious disease ward, medical staff need to do complicated work and wear protective equipment, they cannot monitor the patient's limb movements at all times or clearly, and thus cannot record the patient's condition. Moreover, the patient's unconscious actions occur inadvertently, so it needs to be monitored with the help of the video monitor 700. The video signal of the video monitor 700 is forwarded by the data processor 500 to the prevention and control terminal, and the medical staff of the terminal conducts remote monitoring. It is convenient for the terminal preparation medical staff to adjust the treatment plan for the patient.

Preferably, both the palm restraint sleeve 100 and the elbow restraint sleeve 200 are provided with a restoring force sensor 800. The return force sensor 800 collects the return force with the palm restraint 100 and the elbow restraint 200 restricting at least one dimension of motion of the hand. The data processor 500 can adjust the rate of return of the adjustment elements of the palm restraint 100 and the elbow restraint 200 based on the return force. That is, when restoring the patient's hand, the data processor 500 can adjust the execution rate of the adjustment elements of the palm restraint 100 and the elbow restraint 200 by means of the restoring force, so as to enhance the comfort of the patient.

Preferably, palm motion monitor 300, elbow motion monitor 400 and return force sensor 800 are all wirelessly connected to data processor 500. Preferably, the data processor 500 is not disposed in the elbow restraint sleeve 200 and the palm restraint sleeve 100, the data processor 500 may be disposed in the ICU ward, and is connected with the palm motion monitor 300, the elbow motion monitor 400 and the ICU ward. Sensor devices such as the reset force sensor 800 may be connected by wireless communication through protocols such as Bluetooth and EnOcean. Thus, after wearing the elbow restraint 200 and the palm restraint 100, the patient is visually "cordless" restraint, so that the patient is treated with dignity. Preferably, the elbow motion monitors 400 respectively have at least two, at least one at the upper end of the elbow restraint sleeve 200 (corresponding to the patient's upper arm), and at least one at the lower end of the elbow restraint sleeve 200 (corresponding to the patient's forearm) . Preferably, there is at least one palm motion monitor 300, respectively, which is set to the activity parameter of the palm motion monitor 300, and the activity parameter and the parameter collected by the elbow motion monitor 400 corresponding to the patient's forearm can indirectly reflect the wrist motion. activities of the Ministry.

Preferably, the data processor 500 is connected in communication with the alarm terminal 600 in response to the adjustment signal. The alarm terminal 600 can be presented in at least one prompt manner among sound, light, text, picture, and video when the hand restraint sleeve 100 restricts at least one movement dimension of the patient's palm and wrist. That is to say, when the patient's palm and wrist move intensely, the alarm terminal 600 will record the limitation of the hand and wrist under the restraint of the hand restraint sleeve 100 through sound, light, text, pictures, and images, which can prompt The involuntary movements of medical staff patients are effectively cared for.

Example 2

This embodiment may be a further improvement and/or supplement to Embodiment 1, and repeated content will not be repeated. The entire and/or partial contents of the preferred implementations of other embodiments may be used as supplements to this embodiment without causing conflict or contradiction.

This embodiment provides a restraint device for preventing the dangerous movement of an unconscious hand. As shown in Figures 2 or 3, the restraint device includes an elbow restraint 200 and a palm restraint 100. The elbow restraint 200 is worn on the patient's elbow. The palm restraint sleeve 100 is placed on the inside of the patient's palm and is generally spherical or ellipsoidal, i.e. the palm of the hand. In the present invention, the elbow restraint sleeve 200 is provided with the first air bag 200a. Gas is preliminarily injected into the first air bag 200a. The first air bag 200a is in communication with the trachea 200b arranged on the elbow restraint sleeve 200 . The trachea 200b also communicates with the palm ball 100 . The palm ball 100 is an expandable sphere. In a preferred embodiment of the restraint device provided by the present invention, the elbow restraint sleeve 200 is worn on the patient's elbow, and the patient's hand grasps the ball of the palm. When the patient's upper arm and forearm are bent, the air bag is compressed, the palm ball expands, the patient's fingers are opened by the palm ball, and the finger joints cannot be bent, constraining the finger joints, so that the patient's fingers cannot be extubated; The first air bag 200a is filled with gas, and the first air bag 200a has a reaction force when the upper arm and the lower arm are bent, which can offset the force generated when the upper arm and the lower arm are bent, because the bending of the arm of an unconscious patient is unconscious. , the force generated by it is generally not too large, the air bag has the effect of slowing down the bending tendency of the upper arm and the lower arm, and can effectively buffer the patient's unconscious movements. For patients with endotracheal intubation, to complete the involuntary extubation, the patient must at least have the following actions: the upper and lower arms need to be bent to a certain extent, and the fingers and knuckles are not constrained. In the present invention, when the patient's upper arm and forearm are bent, the first air bag 200a is compressed and inflated to the palm restraint sleeve 100, and the finger joints will expand the palm ball based on the inflation of the first air bag 200a, so that the finger joints are constrained by the palm ball. , so that the patient can not complete the extubation action.

Preferably, when the cuff is worn on the elbow, the first air bag 200a is located between the upper arm and the lower arm. As shown in FIG. 1 , the first air bag 200 a is disposed at the middle position of the elbow restraint sleeve 200 . When worn, the elbow restraint sleeve 200 is partly worn on the forearm and the other portion is worn on the upper arm, and the axis of the first air bag 200a is substantially perpendicular to the axis L between the upper arm and the lower arm. That is, the first airbag 200a is worn on the elbow joint in such a manner that its axial direction is arranged almost in the circumferential direction of the elbow joint. The first air bag 200a can inject gas into the palm restraint sleeve 100 based on the pressure generated when the upper arm and the lower arm form an angle.

Preferably, the elbow restraint sleeve 200 includes an outer bushing 200c and an inner bushing 200d. The outer bushing 200c and the inner bushing 200d are fixedly connected to each other. For example, the outer liner 200c and the inner liner 200d may be bonded or sewn. The inner liner 200d needs to fit the patient's skin, so a material such as cotton can be used for support.

Preferably, the inner bush 200d has a through hole (not shown) for fitting the first airbag 200a. The first air bag 200a is in close contact with the inner side of the outer bush 200c through the through hole. For example, the first airbag 200a may be adhered to the inner side of the outer liner 200c and disposed in the elbow restraint sleeve 200 .

Preferably, the outer bushing 200c includes a gas nozzle 200c-1. The outer sleeve 200c has a cuff cavity (not shown) that can be infused with gas so that the elbow restraint cuff 200 is less prone to flexing and thus the patient's upper and lower arms. For example, during the medical treatment period when the patient has many unconscious movements, the doctor can inject gas into the outer sleeve 200c, so that the patient's upper arm and lower arm are not bent as much as possible. Alternatively, during the medical treatment period in which the patient's involuntary movements are less, the doctor can discharge the gas injected into the outer sleeve 200c, and allow the patient's upper arm and forearm to be able to have some bending motion, at this time, it passes between the upper arm and the forearm The first air bag 200a buffers the bending motion of the upper arm and the lower arm and injects gas into the palm ball to restrain the fingers.

Preferably, the palm restraint sleeve 100 is detachably connected to the trachea 200b. For example, the palm restraint sleeve 100 and the trachea 200b are connected by threads. The palm restraint sleeve 100 has a mouth hole 100d. The mouth hole 100d is in a communication state with the trachea 200b. When the patient's arm and forearm are bent, the first air bag 200a is compressed and inflated to be in an inflated state. When the patient's arm and forearm are stretched, the gas in the palm restraint sleeve 100 is re-exhausted to the first air bag 200a for storage.

Preferably, the gas pipe 200b is a corrugated pipe. It can be adjusted based on the length of the patient's forearm.

Preferably, the palm restraint 100 is provided with at least two finger holes 100c, so that the palm restraint 100 can be worn on the palm. The finger hole 100c is sewn to the ball of the palm. Preferably, the number of finger holes 100c is three, respectively constraining the thumb, middle finger and little finger.

Preferably, the palm restraint sleeve 100 includes an inflatable cavity 100a. The flexible shell 100b includes an outer surface layer, a latex layer, a rubber layer and a memory foam layer in order from the outer layer. The meat filling shell 200a is rotated to form the cavity 200b.

Preferably, the elbow restraint sleeve 200 and the palm restraint sleeve 100 are connected by the support bag plate 900 . The support bag board 900 is made of elastic cotton. The support bladder plate 900 can be used to be considerate of the patient's forearm on the one hand and the trachea 200b can be placed on the other hand. Preferably, the trachea 200b may be bonded to the support bladder plate 900. Alternatively, the support bag plate 900 may be provided with special passages, so that the trachea 200b communicates with the first air bag 200a and the palm restraint sleeve 100 through the passages, respectively.

Preferably, as shown in FIG. 2 , the elbow restraint sleeve 200 adopts a side opening type. That is, the elbow restraint 200 has a wearing side opening 200f for wearing from the arm side. Then, Velcro was used to glue, and the cuff was fastened to the arm with a restraining tape 200g. Because if the unconscious patient cannot speak, the traditional way of wearing the sleeve from both ends makes it difficult for the medical staff to grasp whether the first air bag 200a is aligned with the elbow joint. With this side-opening wearing method, the medical staff can first align the first airbag 200a with the inner side of the elbow joint, and then fix the sleeve to the patient's arm.

Under the condition that the motion posture corresponding to the upper arm motion parameter and the lower arm motion parameter triggers the warning condition, the palm motion monitor 300 collects the hand motion parameters and the wrist motion parameters under the condition that the palm restraint sleeve 100 does not restrict the motion of the hand and the wrist. wrist motion parameters;

Wherein, in the case where the active posture corresponding to the palm motion parameter and the wrist motion parameter triggers the adjustment condition, the adjustment components in the palm restraint sleeve 100 and the elbow motion monitor 400 respond to the adjustment signal of the data processor 500 according to Activate in a manner that limits at least one dimension of motion of the patient's hand to prevent the patient from touching the medical contact device.

Preferably, the data processor 500 is communicatively connected to the alarm terminal 600 in response to the adjustment signal, and the alarm terminal 600 can use sound, light, text, At least one of the prompts in pictures and images is presented.

Preferably, the palm motion monitor 300 is integrated into the palm restraint sleeve 100, thereby constituting the palm control portion. The elbow motion monitor 400 is integrated with the elbow restraint 200, thereby constituting the elbow control. The data processor 500 establishes a data connection with the palm control part and the elbow control part in a wireless connection manner, respectively. The palm control portion and the elbow control portion can establish a dynamic connection in a data-interactive manner with each other, so that in the event that the active posture corresponding to the palm motion parameter and the wrist motion parameter triggers the adjustment condition, the two adjustment components can respond to the data. The adjustment signal of the processor limits at least two dimensions of motion of the patient's hand. That is, the palm control portion and the elbow control portion can be interlocked with each other to simultaneously prevent the patient from touching the medical contact instrument in at least two degrees of freedom. The simultaneous adjustment of the palm control part and the elbow control part in two or more motion dimensions poses a risk of injury to the patient, so the mutual linkage of the palm control part and the elbow control part has overload protection (that is, if the combined limit force of the two exceeds certain amplitude), the hand restraint system of the present invention will give a reset instruction to terminate the adjustment movement regardless of the instruction signal of the data processor 500, and will give an alarm through the alarm terminal 600. The adjustment action in at least two motion dimensions constitutes a preferred technical solution of the present invention, which is suitable for the situation where the patient depends on the equipment for survival (such as the situation on the ventilator and the dialysis machine), wherein the error on the touch-sensitive operation panel Touch itself can have serious and life-threatening consequences. The linkage of the palm control part and the elbow control part can be in a step-by-step manner, and the data processor 500 can pre-determine the resultant force generated by the two step-by-step motions and reset and give an alarm when a specific threshold is exceeded. The adjustment action in at least two motion dimensions constitutes the preferred technical solution of the present invention, and the reason is that it is also suitable for pediatric patients, while preventing the touching of medical contact instruments in a more drastic way, it also protects the patient's moderate Free range of motion. After clinical testing, pediatric patients did not show significant refusal to wear them, that is to say, giving patients an appropriate degree of freedom of movement resulted in a significantly safer movement restriction effect.

The adjustment action in only one motion dimension is the preferred technical solution of the present invention, because the computational analysis workload of the data processor 500 is minimized, and an optimal solution is found between cost and safety. However, when the data processor 500 data-connected with the palm motion monitor 300 and the elbow motion monitor 400 judges according to the motion analysis that a single motion dimension is not enough to prevent the patient from touching the dangerous motion of the medical contact device, the data processor 500 The adjustment movements of the palm control and elbow control (and/or several adjustment components in the palm restraint 100 and the elbow motion monitor 400) will be activated intermittently and/or alternately. During the adjustment movement, the intermittently sequential and/or alternately initiated adjustment actions are preferably performed in a stepwise manner and preferably in one movement direction (movement dimension). During the execution of the adjustment movement in one movement direction (movement dimension), the data processor 500 adjusts the magnitude of the step movement in a single movement direction according to the acceleration of the dangerous movement (the movement performed by the patient when touching the medical contact instrument), Simultaneous analysis determines whether the next movement should be performed by the palm control or the elbow control. "Alternating" means that the palm control part and the elbow control part intervene alternately with each other, respectively executing movements in different movement directions. And "sequentially" means that one of the palm control part and the elbow control part performs several step motions continuously in time, "sequentially" especially performs multiple motions in one direction. The above control method is because, on the one hand, the inventor of the present invention realizes that the bones of bedridden persons are fragile and prone to fractures, and on the other hand, the safety of equipment should also be people-oriented, so the safety of personnel is given priority. Through this control method, it is possible to avoid injury to bedridden patients on the premise of ensuring the reliable operation of medical contact instruments to the greatest extent possible.
