METHOD FOR SUPPORTING BLEEDING TO OBTAIN ARTERIAL BLOOD SAMPLE

[0001] The present invention relates to an arterial blood collecting support apparatus that can more easily grasp an arterial position through an ultrasound image corresponding to a patient's body through an arterial blood collecting support apparatus worn on a patient's body in order to collect arterial blood of a patient.

The arterial blood gas analysis test is a test to analyze the blood gas, which is the gas in the arterial blood, in order to detect the respiratory or circulatory diseases, the patients who are on the ventilator, and also the blood oxygen and carbon dioxide of the patients.

The arterial blood gas analysis test is performed by taking arterial blood mainly present in the patient's wrist in consideration that the arterial blood present on the wrist indicates the gas exchange state in the alveoli.

Before the arterial blood collection, the medical staff felt the radial artery beating only with a finger sensation. Allen's test was performed to confirm the communication between the radial artery and the ulnar artery. After performing the operation, it is judged whether arterial blood sampling is possible or not. After that, a blood sampling needle is placed at a location where the patient's finger senses the artery.

However, such a blood sampling method is an extremely subjective test method which is performed by relying on the sense of a finger of a medical staff, and its accuracy is different according to the skill level of the medical staff. In other words, the lower the proficiency of the medical staff, the more difficult it is to find the exact location of the ureter, the possibility of venous blood collection, and the pain and complications of the patient.

Accordingly, the present invention provides an arterial blood sampling apparatus that can be easily attached to a patient's body and provides an ultrasound image corresponding to a patient's body, thereby enabling an arterial position for arterial blood collection to be more easily grasped.

The present invention also provides an arterial blood sampling apparatus for irradiating light at an arterial position so that an arterial blood sampler can intuitively grasp a blood sampling position.

In addition, it is intended to provide an arterial blood collection support device which can actively adjust the position of an ultrasonic probe according to a medical treatment environment.

According to a first aspect of the present invention, there is provided, as means for solving the above-mentioned problems, a body which is embodied in a form attachable to a patient's wrist; An ultrasonic probe mounted on a bottom surface of the body to acquire an ultrasound image corresponding to a patient's wrist; A touch screen mounted on the upper surface of the body for inputting user requests or displaying ultrasound images; A processor located inside the body for controlling operation of the ultrasonic probe according to a user's request input through the touch screen and displaying ultrasound images acquired through the ultrasonic probe through the touch screen; An arterial position sensing unit sensing and notifying the position of the artery present in the patient's wrist; And an artery position display unit for irradiating light to the artery position sensed by the artery position sensing unit.

The arterial position sensing unit may include a plurality of vibration sensors arranged in a row on a front surface of a bottom surface of the body, and a point where the greatest vibration is sensed is obtained as an arterial position.

Wherein the arterial position sensing unit includes a plurality of infrared sensors and a plurality of Doppler sensors arranged in a row so as to be adjacent to each other on the bottom surface of the body and irradiates infrared rays on the patient's skin through the plurality of infrared sensors, The infrared ray absorbed by the hemoglobin is measured to detect the oxygen saturation and the pulse, and then the highest oxygen saturation or the point where the strongest pulse is sensed is obtained as the artery position.

The arterial position display unit includes a plurality of light sources arranged in a line on a side of a body in contact with a front surface of a bottom surface of the body, and light is irradiated through one of the plurality of light sources according to a result of sensing by the arterial position sensing unit.

In addition, the apparatus comprises a plate-shaped light source panel in which the plurality of light sources are disposed; And an angle adjusting unit installed on a side of a body that is in contact with a front surface of the bottom surface of the body, for adjusting a tilt of the light source panel.

In the present invention, an ultrasonic image corresponding to a patient's body which is wearable in a patient's body is acquired and provided, thereby enabling an arterial blood vessel to perform a blood collection operation more easily and accurately.

In addition, by directly calculating and displaying the arterial position, it is possible for a person without expert knowledge to easily carry out a blood collection operation.

Also, by actively adjusting the position of the ultrasonic probe, the arterial blood collection support device can be more efficiently adapted to various medical treatment environments.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing an appearance of an arterial blood sampling support apparatus according to a first embodiment of the present invention; FIG.

As shown in FIG. 1, the arterial blood collecting support apparatus 10 of the present invention is implemented in a form that can be worn on the wrist of a patient, and acquires and displays an ultrasound image indicating an arterial blood position. Accordingly, the medical staff can obtain arterial blood while confirming the position of the artery existing on the wrist of the patient through the ultrasound image displayed by the arterial blood sampling support apparatus of the present invention.

Hereinafter, the configuration of the arterial blood sampling support apparatus according to the first embodiment of the present invention will be described with reference to FIG.

2, the arterial blood collecting support apparatus 10 according to the present invention includes a body 11 embodied in a form attachable to a wrist of a patient, an ultrasonic probe 12 mounted on the body 12, a processor 13 And a touch screen 14, as shown in Fig.

The body 11 is embodied in a form attachable to the patient's body (particularly the wrist), such as a velcro, an automatic buckle, a wrist band, a patch and a wristwatch form. Of course, in addition to the velcro, automatic buckle, wrist band, patch and wristwatch form, the embodiment may be varied within a range that can be attached to the wrist of the patient.

The ultrasonic probe 12 is mounted on the body 11 so as to be in contact with the wrist of the patient and emits ultrasonic waves to the wrist of the patient and receives ultrasonic waves that are returned to the patient by colliding with erythrocytes flowing in blood vessels in the patient's wrist.

The processor 13 is mounted inside the body 11 to emit and receive ultrasonic waves by driving the ultrasonic probe 12 when the user requests the ultrasonic inspection and analyzes the received ultrasonic waves to obtain ultrasound images of the patient's wrist And then displays it on the touch screen 14. [

In particular, the processor 13 of the present invention derives the arterial blood region and the venous blood region in the ultrasound image of the patient's wrist through the Doppler effect, and overlaps the red pixel in the arterial blood region and the blue pixel in the venous blood region , Allowing the user to intuitively identify these locations.

The touch screen 14 displays the control menu generated by the processor 13 and transmits the user request inputted through the control menu to the processor 13 or controls the operation of the patient 13 under the control of the processor 13. [ And displays the ultrasound image.

In other words, according to the present invention, an arterial blood-sampling support device can be mounted on a patient's wrist, thereby acquiring and displaying an ultrasound image corresponding to the patient's wrist. Thus, a person without expert knowledge can easily grasp the position of an arterial blood and collect blood To provide an arterial blood collection support device.

However, in the case where the arterial blood collecting support apparatus of the present invention is mounted on the wrist of a patient, the arterial blood draw support apparatus acquires and provides ultrasound images of the skin located in the lower region of the apparatus, There is a disadvantage that blood must be collected by inserting an injection into an artery. That is, there is a disadvantage in that the monitoring position of the arterial blood sampling support apparatus is different from the blood sampling position. Therefore, the medical staff has to find the arterial position again by looking at the ultrasound image displayed through the arterial blood collection support device.

Accordingly, in the present invention, an arterial blood sampling support apparatus is constructed as shown in FIG. 4 so that an arterial blood sampling support apparatus can direct an artery position.

4 is a diagram showing a configuration of an arterial blood sampling support apparatus according to a second embodiment of the present invention.

Referring to FIG. 4, the arterial blood collecting support apparatus 10 of the present invention includes an arterial position sensing unit 15 for sensing and notifying the arterial position, and an arterial position sensing unit 15 for sensing It is possible to further include an artery position display unit 16 for informing the user of the artery position by irradiating light at the artery position.

As shown in FIG. 5, the arterial blood located at the wrist has a linearity, so arterial blood at the blood collection site and arterial blood located at the adjacent region are connected to each other and have the same directionality. Therefore, if you know the location of the arterial blood in the area adjacent to the blood collection, that is, the area detected by the arterial blood collection support device, the position of the blood collection part can be easily estimated and guided.

The artery position sensing unit 15 includes at least one of a vibration sensor array, an infrared sensor array, and a Doppler sensor array disposed on a front surface of a bottom surface of the body so as to sense and notify an artery position.

If the arterial position sensing unit 15 of the present invention is embodied as a vibration sensor array including a plurality of vibration sensors S1 to S7 arranged in a row on the front surface of the bottom of the body as shown in FIG. It is possible to sense and notify the position of the artery according to the same principle.

The heart pushes blood along the arteries whenever it is beating. This flow of blood causes the arteries to repeatedly swell and relax, which is referred to as the pulse, and through the skin above the artery, a vibration corresponding to the pulse strength can be felt. Accordingly, if a plurality of vibration sensors are arranged in a row on the front part of the bottom of the body, and then they are brought into contact with the skin, the vibration sensor that touches the skin at the point where the artery passes will sense the greatest vibration. Accordingly, in the present invention, the skin vibration is sensed through a plurality of vibration sensors, and it is determined that the artery is located at the point where the largest vibration is measured.

The arterial position sensing unit 15 includes a plurality of infrared sensors IR1 to IR7 and a plurality of Doppler sensors D1 to D7 arranged in a line so as to be adjacent to the front surface of the body bottom as shown in FIG. The artery position sensing unit 15 irradiates the infrared rays to the skin through a plurality of IR sensors IR1 to IR7 and measures infrared rays absorbed by the hemoglobin through the plurality of Doppler sensors D1 to D7. Based on the results of the infrared measurement, the oxygen saturation and pulse are calculated, and the highest oxygen saturation is detected or the arterial position is obtained at the point where the strongest pulse is detected.

The artery position display unit 16 has a plurality of light sources L1 to L2 arranged in a line on a side of a body that is in contact with a front surface of a bottom surface of the body (i.e., a side surface of the body adjacent to the artery position sensing unit 15). Based on the sensing result of the artery position sensing unit 15, one of the light sources L1 to L2 is turned on so that the light is irradiated to the artery position sensed by the artery position sensing unit 15. [

For example, when the artery position sensing unit 15 has seven vibration sensors and the second one of the seven vibration sensors measures the largest vibration, the artery position display unit 16 corresponds to the second vibration sensor So that the light is irradiated to the arterial position sensed by the arterial position sensing unit 15 in such a manner that the light is irradiated through the second light source.

However, since the radius of the radial artery is about 0.5 cm, it is preferable that the interval between the sensors of the arterial position sensing unit 15 and the interval between the light sources of the arterial position indicator 16 is about 0.5 cm.

In addition, it is preferable that the light of the artery position display unit 16 is irradiated to an area in which the arterial blood collecting assist device is not used (for example, 1.5 to 2 cm in the charge area of the arterial blood collecting assist device).

In the present invention, as shown in FIG. 7, in the present invention, the side surface of the body on which a plurality of light sources are disposed is inclined so that the upper surface of the body has a larger area than the lower surface of the body.

Further, the light source panel (not shown) may include a light source panel (not shown), which is formed in a plate shape and includes a plurality of light sources L1 to L7 arranged in a row, (Not shown) for freely adjusting the inclination of the light source (not shown), and allows the user to manually control the light irradiation angle of the plurality of light sources through the angle adjusting means.

In addition, when it is difficult to guide the position of the artery by light irradiation by the external environment, at least one image or text for guiding the arterial position is displayed by allocating a part of the area of the touch screen to the artery position guidance window. That is, according to the present invention, various methods for guiding artery position can be diversified to suitably cope with various driving environments.

As described above, the arterial blood collection support apparatus of the present invention visually informs the position of the artery to which blood is to be withdrawn, thereby enabling the user to perform a blood collection operation without the hassle of reminding the ultrasound image provided through the arterial blood- It allows intuitive understanding.

In other words, according to the present invention, the ultrasound image corresponding to the wrist of a patient can be visually announced to a blood collection position, thereby allowing a person without expert knowledge to easily perform a blood collection operation.

That is, the arterial blood collecting support apparatus 10 of the present invention can vary the measurement position and the measurement angle of the ultrasonic probe 12 through the probe position varying unit 17. [

More specifically, the moving means 710 includes a pedestal 711 attached to the bottom of the body, a spiral shaft 712 supported by the pedestal 711 and moving the tilting means 720 in the y-axis direction, A guide rail 713 provided parallel to the tilting means 720 for guiding the movement of the tilting means 720 and a helical spindle driving unit 714 for driving the spiral shaft 713 under the control of the processor 13 .

The tilting means 720 includes a support 721 coupled to the spiral shaft 712 and the guide rail 713 and a rotary member 721 supported by the support 721 and tilting the ultrasonic probe 12 attached to the tilting means 720 in the x- (722).

That is, in the present invention, the probe position control menu is configured and provided through the processor 13, and when the user inputs the position value of the probe through the probe position control menu, the processor 13 determines whether or not the profile Axis movement value corresponding to the position value of the x, y axis. The calculated x and y axis movement values are provided to the helical axis driving unit 714 and the rotation unit 722 so that the moving unit 710 and the tilting unit 720 can vary the position of the probe in response thereto do.

In particular, in the present invention, the probe 12 is tilted at a predetermined angle (?), As shown in FIG. 10, so that the probe 12 can acquire an ultrasound image corresponding to a side of the wrist .
