Detailed Description

The invention is described in detail below with reference to the figures and specific embodiments. The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Example one

As shown in fig. 1 to 3, the present embodiment provides an automatic hemostasis pressing device, which includes a support module 1, a transmission module 2, an arm pressing module 3, and an arm supporting module 4.

The support module 1 comprises a base 12 and an annular track frame 11, wherein the annular track frame 11 is vertically arranged on the base 12, and a cavity is formed inside the annular track frame 11 to form a track; the base 12 is in a hollow triangular shape, and the interior of the base is divided into two parts, so that the material cost is reduced, the bearing structure is optimized, the integrity of the device is improved, and the appearance is more attractive.

The arm pressing module 3 and the arm supporting module 4 are respectively arranged at the top and the bottom of the annular track frame 11 and can be stretched up and down in the annular track frame 11. Specifically, the arm support module 4 includes an arm rest 43, a return spring 41, and an arm support bracket 42. The bottom of the circular track frame 11 is provided with a mounting groove 111, the bottom end of the arm support frame 42 is inserted into the mounting groove 111, and the return spring 41 is located in the mounting groove 111 at the lower end of the arm support frame 42. Therefore, the arm support bracket 42 can extend up and down in the mounting groove 111, and the return spring 41 can support the arm support bracket. The arm supporting plate 43 is arranged at the uppermost end of the arm supporting frame 42, and the top surface of the arm supporting plate 43 is arc-shaped and used for placing the arm of the patient. The arm pressing module 3 includes an arm pressing frame 31, and a pressing portion is provided at the lowermost end of the arm pressing frame 31. Two semicircular through hole slots 112 are formed in the top of the annular track frame 11, and the top end of the arm pressing frame 31 penetrates through the through hole slots 112. The middle of the arm pressing frame 31 is provided with a limiting part for limiting the upward movement distance.

The transmission module 2 comprises two transmission units symmetrically arranged at two sides of the circular track frame 11. Each transmission unit includes a slide block 21, a first link 22, and a second link 23. The slide block 21 is provided on the track of the endless track frame 11 and is located in the upper semicircle of the endless track frame 11. The two ends of the first link 22 are respectively connected with the sliding block 21 and the arm pressing frame 31 in a rotating manner, and the two ends of the second link 23 are respectively connected with the sliding block 21 and the arm supporting frame 42 in a rotating manner. The length of each connecting rod is reasonably matched, the arm supporting frame 42 is pushed to gradually descend through the gravity of the arm, and meanwhile, the arm pressing frame 31 above the connecting rods is pulled to descend more greatly than the arm supporting frame 42, so that the arm can be pressed. When in use, the pressing part is sleeved with a disposable gauze sleeve, which is convenient for replacing in time.

The working process and principle of the embodiment are as follows: the patient firstly passes the arm through the annular track frame 11 and is positioned between the arm pressing module 3 and the arm supporting module 4, the arm is straightened and does not contact with the arm pressing module and the arm supporting module, and the venipuncture robot finishes puncture and blood drawing. The patient then moves the arm back slightly and naturally drops onto the arm rest 43 with the puncture located below the arm compression module 3. Under the action of the gravity of the arm, the arm support bracket 42 moves downward, and the arm pressing bracket 31 is driven to move downward by the connecting rod and the sliding block 21. As shown in fig. 4, in the process of moving down the sliding block 21, the distance between the two first links 22 is increased, so that the first links 22 drive the arm pressing frame 31 to move down, and the distance that the arm pressing frame 31 moves down is greater than the distance that the arm supporting frame 42 moves down, thereby achieving rapid pressing hemostasis for the arms. The hemostatic press can be ensured only by keeping the arm of the user, the other hand of the user is not needed to perform the conventional press, and the hemostatic press is very convenient for the old or the handicapped.

Example two

The basic structure of this embodiment is the same as that of the first embodiment, and the difference is that: the arm pressing module 3 includes a pressing mechanism 32 mounted on the bottom of the arm pressing module 3, as shown in fig. 5 and 6. The pressing mechanism 32 includes a pressing push rod 321, a first motor 322, and an ultrasonic sensor. The first motor 322 drives the pressing push rod 321 to move up and down through a gear structure, and the bottom end of the pressing push rod 321 is a suction cup 321a which adopts the existing vacuum suction cup. The ultrasonic sensor is installed at the side of the push rod 321 for detecting whether the lower arm is within a set distance.

The working process and principle of the embodiment are as follows: when in use, a hemostatic patch is sucked under the suction cup 321 a. When the arm pressing module 3 descends, the ultrasonic sensor responds and starts monitoring. When the ultrasonic sensor detects that a certain distance is reached to the arm of the human body, the first motor 322 starts to work, the pressing push rod 321 is driven to downwards push the two-section type hemostatic patch, and the hemostatic patch is attached to the acupuncture point. A pressure sensor is also arranged between the pressing push rod 321 and the suction cup 321a, when the set pressure is reached, the first motor 322 is controlled to rotate reversely, and the suction cup 321a is closed, so that the tourniquet 5 is pressed at the puncture to keep the hemostasis pressing. This structure and transmission module 2 cooperate each other, can be so that the stroke of pressing push rod 321 is lower, be favorable to the miniaturization of structure and realize job stabilization nature and sensitivity.

EXAMPLE III

In this embodiment, which is a modified version of the second embodiment, the arm pressing module 3 further includes a tourniquet replacing unit 33, as shown in fig. 7. The tourniquet replacement unit 33 comprises a pulley 332 and a second motor 331. The second motor 331 is connected to a rotation shaft of the pulley 332, the tourniquet 5 is wound on the pulley 332, and the tourniquet replacement unit 33 is provided with an outlet slot 333 facing the pressing push rod 321 such that one end of the tourniquet 5 passes through the outlet slot 333. The tourniquet 5 is formed by connecting tourniquets with protective films, and the adjacent tourniquets are in virtual electrical connection. A knife edge may also be provided below the outlet slot 333. When one pressing operation is finished, the second motor 331 may drive the pulley 332 to extend the tourniquet 5 out of the exit slot 333. The suction cup 321a of the push rod 321 is pressed to start sucking the tourniquet 5, and then in the process of moving downwards, the tourniquet 5 is cut by the outlet slot 333 to form a hemostatic sheet, namely a hemostatic patch, so that the hemostatic patch is automatically replaced.
