Description

Technical Field

[0001] This utility model relates to the field of emergency treatment equipment technology, specifically to a pressure-type hemostat. Background Technology

[0002] In daily life and work, accidental cuts to the limbs are common, requiring timely and effective hemostasis. For small and short cuts, direct pressure is commonly used to stop the bleeding. Existing common pressure-based hemostatic devices generally consist of a ties and a pressure block attached to the ties. To use, the pressure block is first secured to the cut with the ties, and then the outer cap of the pressure block is screwed on to tighten it against the cut, achieving hemostasis. This type of hemostatic device has the following drawbacks:

[0003] (1) The two sides of the cut wound are generally separated from each other, and it is difficult to close the cut during the pressing process, resulting in slow hemostasis and healing speed. Due to the large gap of the cut during the healing process, the appearance is affected after healing.

[0004] (2) The fixed size of the directional push-type pressing block cannot be rotated, making it difficult to cover the slightly longer oblique cuts;

[0005] (3) When the pressing block with the rotating function is twisted and pushed, in addition to being pushed into the skin incision, the pressing block also has a certain torsional force, which can easily cause the incision on the skin to deform. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the defects of existing pressure hemostats, such as the inability to align wounds, difficulty in covering oblique long incisions, and easy deformation of the incision. It provides a pressure hemostat that can push the two sides of the incision towards the center to align during the pressure hemostasis process, thereby improving the hemostasis speed and healing effect. Under the premise that the pressure bar can be rotated and adjusted, the lateral rotation of the pressure bar can be restricted during the pushing and tightening process, thereby eliminating the torsional force that causes incision deformation.

[0007] This pressure-type hemostat includes a ligature and a pressing component mounted on the ligature. The ligature has a fixed positioning ring and a guide plate movably fitted into an annular groove on its inner wall. The positioning ring has several circumferentially oriented positioning tenons extending into the annular groove. The guide plate has several upwardly protruding limiting tenons on its upper surface that mate with the positioning tenons. A through hole is located in the center of the guide plate, and a pair of guide holes are located outside the through hole. The pressing component includes a cap and a pressing head. The central part has a threaded tube. The pressing head includes a rectangular pressing plate, a screw located in the center of the upper surface of the pressing plate, a guide rod located on the upper surface of the pressing plate and adapted to the guide hole, a pair of inner push ribs formed on both sides of the lower surface of the pressing plate, and a silicone block detachably installed on the lower surface of the pressing plate and located between the two inner push ribs. The cap is rotatably connected to the guide plate. The screw and guide rod of the pressing head pass through the central through hole and the two guide holes of the guide plate, respectively. The upper end of the screw is threaded into the threaded tube inside the cap.

[0008] Furthermore, the inner push ridge is an elastic pressure strip with an arc-shaped bottom. The outer side of the inner push ridge is fixedly connected to the edge of the pressing sheet, and the inner side of the inner push ridge bends outward and folds back. The bottom of the thin-walled sheet-like inner push ridge deforms under pressure, narrowing and elongating inward during the process. The inner folded-back area is not connected to the pressing sheet, and pushes the silicone block inward during this process.

[0009] Furthermore, the width of the annular groove is greater than the overall thickness of the guide plate and its limiting tenon.

[0010] Furthermore, the guide plate has an L-shaped groove formed on its surface, the cap has an outwardly extending flange at its lower edge, and the threaded tube has an H-shaped groove formed at its lower end; the flange is embedded in the L-shaped groove, and the through hole is embedded in the H-shaped groove.

[0011] Furthermore, one end of the cable tie is provided with a buckle, and the outer surface of the other end of the cable tie is provided with Velcro.

[0012] Furthermore, the screw cap sidewall is provided with longitudinal anti-slip ridges.

[0013] This utility model discloses a pressure-type hemostat that overcomes the shortcomings of existing pressure-type hemostats, such as the inability to align wounds, difficulty in covering long oblique incisions, and the tendency to cause incision deformation. It can push the two sides of the incision towards the center for alignment during the pressure hemostasis process, thereby improving the hemostasis speed and healing effect. With the pressure bar being rotatable and adjustable, it can limit the lateral rotation of the pressure bar during the pushing and tightening process, thus eliminating the torsional force that causes incision deformation.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0033] In the description of this utility model, it should be understood that the terms "left", "right", "front", "rear", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] The present invention will be further described below with specific embodiments, but the scope of protection of the present invention is not limited to the following embodiments.

[0035] Implementation method 1: such as Figures 1 to 8As shown, this pressure-type hemostat includes a tying band 1 and a pressing component 2 disposed on the tying band 1. The tying band 1 has a positioning ring 11 fixedly mounted on it and a guide plate 12 movably fitted into an annular groove 111 formed in the inner wall of the positioning ring 11. The positioning ring 11 has several positioning tenon holes 112 extending circumferentially into the annular groove 111. The upper surface of the guide plate 12 has several upwardly protruding limiting tenons 121 that fit the positioning tenon holes 112. A through hole 122 is formed in the center of the guide plate 12, and a pair of guide holes 123 are formed outside the through hole 122. The pressing component 2 includes a cap 21 and a pressing head 22. A threaded tube 21 is provided in the center of the cap 21. 1. The pressing head 22 includes a rectangular pressing plate 221, a screw 222 disposed in the center of the upper surface of the pressing plate 221, a guide rod 223 disposed on the upper surface of the pressing plate 221 and adapted to the guide hole 123, a pair of inner push ribs 224 formed on both sides of the lower surface of the pressing plate 221, and a silicone block 225 detachably installed on the lower surface of the pressing plate 221 and located between the two inner push ribs 224; the cap 21 is rotatably connected to the guide plate 12, and the screw 222 and the guide rod 223 of the pressing head 22 pass through the central through hole 122 and the two guide holes 123 of the guide plate 12 respectively, and the upper end of the screw 222 is threaded into the threaded tube 211 inside the cap 21.

[0036] Implementation Method 2: The inner push rib 224 of this pressure-type hemostat is an elastic pressure strip with an arc-shaped bottom. The outer side of the inner push rib 224 is fixedly connected to the edge of the pressure plate 221, and the inner side of the inner push rib 224 bends outward and folds back. The bottom of the thin-walled, sheet-like inner push rib deforms under pressure, narrowing and elongating inward during the process. The folded-back area on the inner side is not connected to the pressure plate, and pushes the silicone block inward during this process. The remaining structures and components are as described in Implementation Method 1 and will not be described again.

[0037] Implementation Method 3: The width of the annular groove 111 of this pressure-type hemostat is greater than the overall thickness of the guide plate 12 and its limiting tenon 121. This allows the guide plate to have space for vertical movement within the annular groove on the inner wall. When not secured, the guide plate hangs on the lower surface of the annular groove under natural gravity, allowing free rotation between the two. Figures 9 to 11 As shown; during the tightening process of the cable tie, the pressing plate is pressed and driven by the screw and cap to move the guide plate upward relative to the positioning ring. The limiting tenon inserts into the nearby positioning hole, and the guide plate is limited. Then, by using the cooperation between the guide hole and the guide rod, the pressing plate can no longer rotate during the subsequent downward pressing process, as shown. Figures 12 to 14The design eliminates skin twisting and prevents torsional forces that could cause incision deformation. The guide plate 12 has an L-shaped groove 124 on its surface, the cap 21 has an outwardly extending flange 212 along its lower edge, and the threaded tube 211 has an H-shaped groove 213 at its lower end. The flange 212 is fitted into the L-shaped groove 124, and the through hole 122 is fitted into the H-shaped groove 213. This design enables the cap to rotate on the guide plate. The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0038] Embodiment 4: The ligature 1 of this pressure-type hemostat has a buckle 13 at one end and a Velcro closure on the outer surface of the other end. It is used to wrap around the arm or leg to fix the position of the pressure pad and to provide initial fixation for the operation of the pressure pad to press the incision inward. After wrapping, the adhesive end of the ligature with Velcro passes through the buckle and is folded back, and the fixation is completed using the back Velcro closure. The remaining structure and components are as described in Embodiment 1 and will not be described again.

[0039] Embodiment 5: The cap 21 of this pressure-type hemostat has a longitudinal anti-slip ridge 214 on its side wall. This facilitates the application of force by the fingers when rotating the cap. The remaining structures and components are as described in Embodiment 1 and will not be described again.

[0040] In use: Hold the cap and press the pressure pad onto the incision along the incision direction, ensuring that the center line of the silicone block roughly covers the incision. Rotate the bandage perpendicular to the arm or leg and wrap it around the incision. Pass the adhesive end of the bandage through the buckle and fold it back, securing it with Velcro. During tightening, the guide plate moves upward in the annular groove under the action of the pressing component. The limiting tenon inserts into the positioning tenon hole to fix the position of the guide plate on the positioning ring, thus determining the inclination of the pressure pad relative to the bandage. With the cooperation of the guide hole and guide rod, the pressure pad will no longer be able to rotate. Tighten the cap, and the threaded tube drives the screw downward, causing the pressure pad to compress the wound. The inward-pushing rhombuses on both sides below the pressure pad push the silicone block inward, causing the silicone block to pull the skin on both sides of the incision inward, achieving the alignment of the incision and simultaneously completing the compression and hemostasis above the incision.

[0041] This pressure-type hemostat overcomes the shortcomings of existing pressure-type hemostats, such as the inability to align wounds, difficulty in covering long oblique incisions, and the tendency to cause incision deformation. It can push the two sides of the incision towards the center to align during the pressure hemostasis process, improving the hemostasis speed and healing effect. With the pressure bar being adjustable by rotation, it can limit the lateral rotation of the pressure bar during the pushing and tightening process, eliminating the torsional force that causes incision deformation.
