Description

Technical Field

[0001] The utility model relates to the field of pneumatic tourniquets, in particular to a pneumatic hemostatic binding structure. Background Art

[0002] The hemostatic binding structure refers to the tourniquet hemostasis method. Tourniquet hemostasis is a simple and effective hemostasis method used for first aid of severe bleeding in the limbs. It achieves the purpose of hemostasis by compressing blood vessels to block blood flow. However, if used improperly or for too long, the tourniquet can cause ischemia and necrosis of the distal limbs. For this reason, a tourniquet can only be used when bleeding is severe and other methods cannot stop bleeding.

[0003] With the development of technology, manual tourniquet binding is less common. The existing electric pneumatic hemostat is a medical device commonly used in operating rooms, emergency rooms, rehabilitation centers and some other medical institutions. Its main function is to achieve the effect of hemostasis by applying a certain air pressure to the tourniquet. It can effectively reduce surgical bleeding, shorten operation time, and reduce the incidence of surgical complications, thereby improving the safety and effectiveness of the operation.

[0004] However, during the use of the existing pneumatic hemostat, the trachea inside the tourniquet needs to be connected with the trachea of ​​the hemostat, and it needs to be tested for air leakage before the operation. Once the air leakage problem is detected, the trachea needs to be replaced. During the existing replacement process, the trachea of ​​the hemostat needs to be connected with the trachea in the tourniquet, and the snap structure is pressed to open the snap joint, so that the trachea can be inserted for connection. In order to ensure the airtightness of the connection, the opening and closing of the snap is greatly restricted, which results in a large force being consumed in the process of pressing the snap. At the same time, in the process of replacing the trachea, it takes more time to open the snap, which affects the staff who urgently need to perform the operation. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a pneumatic hemostatic binding structure to solve the technical problems mentioned in the above background technology.

[0009] By adopting the above technical solution and setting a movable ring, the fixed ring and the plug block can be stably fixed. The movable ring is squeezed to displace the movable rod, so that the position of the block can be restricted and fixed, avoiding shaking of the block during use, which would cause the overall air pressure leakage.

[0010] The utility model is further configured that movable rods are movably installed on both sides of the fixing ring, and a second spring is installed at one end of the movable rod, a clamping plate is fixedly installed in the middle of the movable rod, and one end of the movable rod is configured as an arc surface.

[0011] By adopting the above technical solution and setting a clamping plate, the position of the movable rod is limited to avoid the position of the movable rod being offset during the movement, thereby preventing the problem of overall fixation failure.

[0012] The utility model is further configured that a limiting groove is provided on one side of the movable groove, and the limiting groove matches with the limiting block, and the movable ring is rotatably connected with the movable groove.

[0013] By adopting the above technical solution and setting the movable groove, the movement of the movable ring is limited, so that the overall squeezing and fixing effects are better, and the problem of the movable ring falling off during the movement is avoided.

[0014] The utility model is further configured that a third spring is installed on one side of the movable plate, and the movable plate is connected to the fixed ring through the third spring, a limiting rod is fixedly installed on one end of the limit block, and a groove matching the limiting rod is opened inside the fixed ring.

[0015] By adopting the above technical solution and setting the third spring, the resetting effect of the movable plate is improved. After contact resetting, the third spring can move the slider, thereby providing a certain thrust for replacing the air pipe without the need for staff to pull it out laboriously.

[0016] In summary, the utility model mainly has the following beneficial effects:

[0017] The utility model provides a movable plate and a slider, when the insert block is inserted into the fixed ring, the slider slides along the slide groove, when the slider moves to a certain position, it contacts the movable plate, so that the movable plate is squeezed, under the action of the movable shaft, the movable plate rotates, so that the clamping block contracts, and the insert block is fixed at the same time, and the insert block can be limited and fixed by manual insertion. The whole is relatively simple, and the limiting effect is more, and there will be no displacement problem. The movable ring is rotated by rotating the movable block, and the movable rod is squeezed to displace the other end of the movable rod, which clamps the displacement of the movable plate, so that the movable plate is limited, thereby limiting the overall position, ensuring that the limiting effect is sufficient, and it is more labor-saving, which greatly improves work efficiency.

When the slider 20 slides a certain position inside the slide groove 22, the slider 20 gradually begins to contact the movable plate 13. At this time, the movable plate 13 is squeezed by the slider 20 and rotates under the action of the movable shaft 18, while squeezing the third spring 15. When one end of the movable plate 13 is displaced, the other end contracts toward the middle, thereby driving the clamping block 7 to move. At this time, the clamping block 7 covers one end of the plug block 4, thereby achieving preliminary limit clamping.

[0028] See also Figure 3 , 6 A movable groove 23 is provided at one end of the fixed ring 3, and a movable ring 8 is movably installed in the movable groove 23, a movable block 9 is fixedly installed on one side of the movable ring 8, a first spring 11 is installed inside the movable block 9, and a limiting block 10 is installed at one end of the first spring 11, the limiting block 10 is connected to the movable block 9 by the first spring 11, and the movable ring 8 is provided so that the fixed ring 3 and the plug 4 can be stably fixed, and the movable rod 16 is displaced by the extrusion of the movable ring 8, so that the position of the block 7 can be limited and fixed, so as to avoid the shaking of the block 7 during use, thereby causing the problem of overall air pressure leakage.

[0029] See also Figure 3-4 A movable rod 16 is movably installed on both sides of the fixed ring 3, and a second spring 14 is installed at one end of the movable rod 16. A clamping plate 17 is fixedly installed in the middle of the movable rod 16. One end of the movable rod 16 is set as an arc surface. By setting the clamping plate 17, the position of the movable rod 16 is limited to avoid the position of the movable rod 16 from shifting during the movement, thereby causing the problem of overall fixation failure.

[0030] See also Figure 6 A limiting groove 21 is provided on one side of the movable groove 23, and the limiting groove 21 cooperates with the limiting block 10. The movable ring 8 and the movable groove 23 are rotatably connected. By setting the movable groove 23, the movement of the movable ring 8 is limited, thereby making the overall extrusion and fixing effects better and avoiding the problem of the movable ring 8 falling during the movement.

[0031] See also Figure 4 A third spring 15 is installed on one side of the movable plate 13, and the movable plate 13 is connected to the fixed ring 3 through the third spring 15. A limiting rod 12 is fixedly installed on one end of the limit block 10, and a groove matching the limiting rod 12 is opened inside the fixed ring 3. By setting the third spring 15, the resetting effect of the movable plate 13 is better. After contact resetting, the third spring 15 can move the slider 20, thereby providing a certain thrust for replacing the trachea without the need for staff to pull it out laboriously.

[0032] The working principle of the utility model is as follows: the fixing blocks 19 on both sides of the insert block 4 are aligned with the fixed ring 3 and inserted, so that the slider 20 slides inside the slide groove 22, and then the insert block 4 is pushed in. After the slider 20 slides a certain position inside the slide groove 22, the slider 20 gradually begins to contact the movable plate 13. At this time, the movable plate 13 is squeezed by the slider 20 and rotates under the action of the movable shaft 18, squeezing the third spring 15 at the same time. When one end of the movable plate 13 is displaced, the other end contracts toward the middle, thereby driving the clamping block 7 to move. At this time, the clamping block 7 covers one end of the insert block 4, thereby achieving preliminary limit clamping. At this time, the movable block 9 is rotated to rotate the movable ring 8. When the movable ring 8 rotates, the first spring 1 1 applies pressure to the limit block 10, at which time one end of the limit block 10 contacts the movable groove 23 and is limited by the movable groove 23. When the movable ring 8 continues to rotate, the movable ring 8 contacts the movable rod 16, so that the movable rod 16 is squeezed and shrinks inward. When the movable rod 16 moves, one end of the movable rod 16 clamps the displacement path of the movable plate 13, so that the movable plate 13 is limited. Under the action of the movable rod 16, the reset effect of the third spring 15 is limited. When it moves to a certain position, the limit block 10 contacts the limit groove 21. At this time, the limit block 10 is no longer limited by the movable groove 23. Under the action of the first spring 11, the limit block 10 enters the inside of the limit groove 21, so that the whole is fixed.
