Description

Technical Field

[0001] The present invention particularly relates to an abdominal hemostasis device. Background Art

[0002] When there is massive bleeding in the abdominal cavity, the bleeding speed is very fast and the amount of bleeding is very large, which may endanger life in a short period of time. At this time, it is necessary to quickly find the bleeding point and stop the bleeding, otherwise it may lead to serious consequences.

[0003] Gauze packing is a simple and effective method of stopping bleeding. Packing gauze on the bleeding site can slow down the bleeding by compressing the bleeding point, thus buying time for further treatment.

[0004] The existing method of packing gauze is: place the hemostatic gauze roll just above the bleeding point, and then use the two thumbs to pull and press down alternately to pack the hemostatic gauze. However, this method has the following disadvantages:

[0005] 1. Speed ​​problem: Since the gauze packing is operated by two thumbs and is performed alternately, it requires certain coordination of the operator's movements. If the movements are not coordinated enough, the packing speed will definitely be affected;

[0006] 2. Fatigue problem: Since packing gauze over a large area requires extremely fast speed and a relatively long time, it will cause fatigue of the thumb in the later stage of packing, which will affect the packing speed. Summary of the invention

[0007] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an abdominal hemostasis device, which can greatly reduce the workload of medical staff and at the same time greatly improve the packing speed to achieve the purpose of rapid hemostasis.

[0017] Furthermore, the left and right guide mechanism also includes two first guide wheels, and the two first guide wheels are rotatably arranged at both ends of the guide groove.

[0018] Furthermore, the stuffing mechanism includes two plugs and an alternating driving member. The two plugs are arranged opposite to each other and are located on the left and right sides of the gauze strip coming out of the left and right guide mechanisms.

DETAILED DESCRIPTION

[0033] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0034] See also Figures 1 to 4 The present invention provides an abdominal hemostasis device, which includes a support frame 100, a mounting plate 200, a winding drum 300, a wire pulling mechanism 400 and a left and right guide mechanism 500.

[0035] Specifically, the mounting plate 200 is vertically arranged on the support frame 100 for installing other parts. The winding drum 300 is installed on the mounting plate 200, on which the gauze strip that can be pulled out freely is wound. The wire pulling mechanism 400 is connected with the gauze strip, and is used to continuously pull the gauze strip downward. The left and right guiding mechanisms 500 are used to alternately guide the gauze strip pulled by the wire pulling mechanism 400 horizontally to the left and right so that the gauze stack is laid on the surface of the bleeding point. The stuffing mechanism 600 is used to squeeze the gauze laid on the surface of the bleeding point into the bleeding point in the gap.

[0036] During use, when the patient is in a lying position, the support frame 100 is quickly fixed, and the wire pulling mechanism 400 is located above the bleeding point. Subsequently, the wire pulling mechanism 400, the left and right guide mechanisms 500 and the filling mechanism 600 are started. The wire pulling mechanism 400 pulls down the gauze strip, and the left and right guide mechanisms 500 drive the gauze strip to move horizontally left and right, so that the gauze is stacked and laid on the surface of the bleeding point. Then, the filling mechanism 600 squeezes the gauze laid on the surface of the bleeding point into the bleeding point through the gap.

[0037] By using a hemostatic device, during the hemostatic process, the pulling and packing of the gauze strips are completed by a machine, which can greatly reduce the workload of medical staff. At the same time, the packing speed can be adjusted by the wire pulling mechanism 400, the left and right guide mechanisms 500 and the packing mechanism 600, thereby greatly improving the packing speed and achieving the purpose of rapid hemostasis.

[0038] In this embodiment, the wire pulling mechanism 400 includes a first rotating power source, a driving wheel 410 and a driven wheel 420. The driven wheel 420 and the driving wheel 410 are arranged on the mounting plate 200 at intervals, and the wire coming out of the winding drum 300 passes between the driving wheel 410 and the driven wheel 420. The first rotating power source is used to drive the driving wheel 410 to rotate. When the first rotating power source drives the driving wheel 410 to rotate, the driving wheel 410 and the driven wheel 420 rotate in coordination to pull the gauze strip downward.

[0039] In this embodiment, the left and right guide mechanism 500 includes a guide block 510 and a lateral motion driving source 520. A lateral extending guide groove is provided on the mounting plate 200, and the end of the guide block 510 can be slidably clamped in the guide groove. The lateral motion driving source 520 is connected to the guide block 510 and is used to drive the guide block 510 to move back and forth along the guide groove. A through hole is provided on the guide block 510 that runs through from top to bottom, and the gauze strip pulled down from the wire pulling mechanism 400 can slide through the through hole.

[0040] When in use, when the driving wheel 410 and the driven wheel 420 roll, the gauze strip is pulled downward and falls freely. When the lateral motion driving source 520 drives the guide block 510 to move back and forth left and right, the gauze strip is laid and stacked on the bleeding point, which is convenient for the packing mechanism 600 to pack.

[0041] As a preferred embodiment, in specific implementation, the left and right guide mechanism 500 further includes two first guide wheels, which are rotatably arranged at the two ends of the guide groove. When the gauze strip is close to the left and right ends, the friction between the gauze strip and the two ends of the guide groove can be reduced by the two first guide wheels, so that the gauze strip can fall freely.

[0042] In this embodiment, the packing mechanism 600 includes two plugs 610 and an alternating driving member 620. The two plugs 610 are arranged opposite to each other and are located on the left and right sides of the gauze strip coming out of the left and right guide mechanisms 500. The alternating driving member 620 is connected to the two plugs 610 and is used to drive the two plugs 610 to alternately press the gauze laid above the bleeding point into the bleeding point when the guide blocks 510 on the same side are away from each other.

[0043] By alternately packing with two plugs 610, interference between the plugs 610 and the descending gauze strip can be prevented. At the same time, one plug 610 can be packed upward while the other plug 610 is packed downward, which can greatly increase the packing speed and reduce the hemostasis time.

[0044] Specifically, the alternating driving member 620 includes a second rotating power source 621, a sprocket 622, a chain 623, and a driving rod 624. Two arc-shaped grooves with downward openings are oppositely provided on the mounting plate 200, and the plug 610 is slidably clamped in the arc-shaped grooves through a slider, and the lower ends of the two arc-shaped grooves intersect, and the intersection is directly opposite to the bleeding point.

[0045] The two sprockets 622 are respectively located at the centers of the two arc-shaped grooves, and are rotatably mounted on the mounting plate 200 and connected by a chain 623. The second rotating power source 621 is connected to one of the sprockets 622. In this embodiment, the second rotating power source 621 is any mechanism that drives the sprocket 622 to rotate in both directions, such as a rotating motor, manual rotation, etc. The sprocket 622 and the chain 623 can also be implemented by other methods, such as a pulley, a gear rack method.

[0046] The ends of the driving rod 624 are fixed on the rotating shafts of the two sprocket wheels 622, and the angle between the two driving rods 624 is 90 degrees. The driving rod 624 is provided with a slide groove along its length direction, and two sliders can be slidably clamped in the slide groove on the same side thereof.

[0047] When in use, the second rotating power source 621 is started to drive the two sprockets 622 to rotate in the same direction, and drives the driving rod 624 to rotate at the same time. The angle between the two driving rods 624 is always maintained at 90°, that is: when the left driving rod 624 is in a vertical state, the plug 610 connected thereto is at the highest point, and the guide block 510 is at the far left. At the same time, the right driving rod 624 is in a horizontal state, and the plug 610 connected thereto is in the lowest state and the gauze is inserted into the bleeding point, and vice versa.

[0048] As a preferred embodiment, in order to ensure that the left and right movement frequency of the guide block 510 is synchronized with the filling frequency of the two plugs 610, in a specific implementation, the lateral motion driving source 520 includes a second guide wheel 521, a fixed wheel 522, a pull rope 523 and an elastic member 524. The second guide wheel 521 is arranged on the mounting plate 200, and the fixed wheel 522 is on the central axis of one of the sprockets 622. One end of the pull rope 523 is wound around the fixed wheel 522, and the other end of the pull rope 523 is connected to the guide block 510 after passing the second guide wheel 521. The pull rope 523 can pull the guide block 510 to slide along the slide groove. The two ends of the elastic member 524 are respectively connected to the guide block 510 and the mounting plate 200, and can provide a pulling force to the guide block 510 in the opposite direction of the pulling direction of the pull rope 523.

[0049] For example, the driving rod 624 on the left is in a vertical state, the guide block 510 is at the far left, and the elastic member 524 is in a stretched state. When the second rotating power source 621 drives the fixed wheel 522 to rotate clockwise, the driving rod 624 rotates clockwise and drives the plug head 610 on the left to move downward along the right side of the arc-shaped groove eccentrically and approach the bleeding point. At this time, the fixed wheel 522 releases the line, the elastic member 524 contracts, and the guide block 510 is pulled to slide to the right, so that the gauze can be driven to the right and laid on the bleeding point. When the plug head 610 on the left moves downward, the gauze can be moved to the right and laid on the bleeding point. When it reaches the lowermost end, the gauze can be pressed into the bleeding point. At this time, the driving rod 624 on the right is in a vertical state, and the plug 610 on the right is at the highest point; then, the second rotating power source 621 drives the chain 623 to rotate in the opposite direction, and the driving rod 624 on the right rotates counterclockwise downward and to the left, driving the plug 610 on the right to move downward and the plug 610 on the left to move upward. At this time, the fixed wheel 522 is reeled in, and the pull rope 523 pulls the guide block 510 to move to the left, so that the gauze strip can be laid to the left, which is convenient for filling the plug 610 on the right.

[0050] In addition, during specific implementation, the second guide wheel 521 can be arranged at the same height as the slide slot to facilitate pulling of the pull rope 523 .

[0051] Specific implementation of the above abdominal hemostasis device:

[0052] When in use, the patient is placed in a supine position, the support frame 100 is quickly fixed, and the pulling wire mechanism 400 is located above the bleeding point. Subsequently, the first rotating power source and the second rotating power source 621 are started, and the driving wheel 410 and the driven wheel 420 pull the gauze strip down, and the left and right packing heads 610 alternately press the gauze into the bleeding point.

[0053] By using a hemostatic device, during the hemostatic process, the pulling and packing of the gauze strips are all completed by a machine, which can greatly reduce the workload of medical staff. At the same time, the packing speed can be adjusted by the rotation speed of the first rotary power source and the second rotary power source 621, thereby greatly improving the packing speed and achieving the purpose of rapid hemostasis.
