Description

Technical Field

[0001] This invention relates to the field of emergency medical technology, specifically to a wound healing and compression clamp for combat trauma. Background Technology

[0002] In war trauma, uncontrollable massive bleeding in the limbs is the leading cause of preventable death. In emergency situations, life can be saved through professional first aid and hemostasis procedures.

[0003] Chinese patent CN113349868B discloses a combat trauma emergency hemostasis and pressure clamp, comprising: a hinge, a first fixing shell, and a second fixing shell. The first fixing shell is located on one side of the bottom of the hinge, and the second fixing shell is located on the other side of the bottom of the hinge. An annular airbag is provided on the inner wall of both the first and second fixing shells. By continuously pressing the air supply plug with external force, the plug continuously draws gas into its interior through a second one-way valve and delivers the gas to the interior of the air delivery tube through the first one-way valve. The air delivery tube connects the interior of the annular airbag and the interior of the air supply plug. When gas inside the air supply plug enters its interior through the first one-way valve, it is delivered to the interior of the annular airbag under continuous pressure. After the gas enters the interior of the annular airbag through the air delivery tube, it covers and wraps the wound of the wound. The annular airbag gradually tightens its wrapping around the wound, achieving hemostasis. This provides gentle pressure to the injured area and reduces pain. However, combat trauma easily forms open wounds, and hemostasis by simply applying pressure to the wound is ineffective.

[0004] Based on this, the present invention designs a combat trauma emergency hemostasis and compression clamp to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a combat trauma emergency hemostasis and compression clamp.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A combat trauma emergency hemostasis and compression clamp includes a support plate and fixing straps passing through both ends of the support plate; A boss is fixed to the upper end of the support plate, and a disinfection dressing is fixedly installed at the lower end of the support plate. An adjustable single-point pressing mechanism is installed on the boss. The adjustable single-point pressing mechanism includes a coarse adjustment component, a fine adjustment component, and a pressing block. The coarse adjustment component is installed on the boss, the fine adjustment component is installed inside the coarse adjustment component, and the pressing block is installed inside the fine adjustment component. The support plate is equipped with a rapid adsorption mechanism, which is located between the disinfectant dressing and the pressure block. The rapid adsorption mechanism is used to adsorb blood flowing out of the wound to ensure a clear view around the wound. The support plate is also equipped with a wound traction mechanism, which is used to pull the skin around the wound to reduce the size of the wound.

[0007] Furthermore, the coarse adjustment assembly includes an outer sleeve and an inner sleeve. A limiting groove is formed on the boss. The outer sleeve is rotatably connected to the boss through a bearing. The inner wall of the outer sleeve is threadedly connected to the outer wall of the inner sleeve, and the inner sleeve is slidably connected to the limiting groove.

[0008] Furthermore, the fine-tuning assembly includes a screw and a connecting plate. The connecting plate is fixedly connected to the inner wall of the inner sleeve, and the pressure block is slidably connected to the inner wall of the inner sleeve. The lower end of the screw is rotatably connected to the pressure block through a bearing, and the upper end of the screw is threadedly connected to the connecting plate.

[0009] Furthermore, the pitch of the thread between the outer sleeve and the inner sleeve is greater than the pitch of the thread between the screw and the connecting plate.

[0010] Furthermore, a pad layer is fixedly installed at the lower end of the pressure block.

[0011] Furthermore, the wound traction mechanism is equipped with at least two sets.

[0012] Furthermore, the wound traction mechanism includes a fixed column, a traction block, a connecting assembly, a take-up roller, a rotating shaft, a first knob, and a one-way rotating assembly. The rotating shaft is rotatably connected to the wound traction mechanism via bearings. A take-up roller is fixedly installed at the lower end of the rotating shaft, and a first knob is fixedly installed at the upper end of the rotating shaft. The fixed column is fixedly connected to the support plate, and a pull rope is fixedly installed between the fixed column and the take-up roller. A connecting assembly for fixing the traction block to the skin is installed at the lower end of the traction block. A one-way rotating assembly for controlling the unidirectional rotation of the rotating shaft to wind up the pull rope is also installed on the traction block.

[0013] Furthermore, the rapid adsorption mechanism includes a bracket, an unwinding shaft, a rewinding shaft, an adsorption tourniquet, and a knob. Two brackets are symmetrically fixedly installed on the front and rear sides of the support plate. The unwinding shaft and the rewinding shaft are rotatably installed on the two brackets respectively. The two ends of the adsorption tourniquet are fixedly connected to the unwinding shaft and the rewinding shaft respectively, and the adsorption tourniquet passes between the sterile dressing and the pressure block. The end of the rewinding shaft is fixedly connected to the knob.

[0014] Furthermore, damping is provided between the unwinding shaft and the bracket, and between the winding shaft and the bracket.

[0015] Furthermore, the connecting components utilize skin hooks or adhesive.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: After initial cleaning and disinfection of the wound, the support plate is fixed to the wound with a fixing strap, and the pressure block is aligned with the wound. Then, the wound traction mechanism pulls the skin around the wound to reduce the wound size. Then, through the cooperation of the coarse adjustment component and the fine adjustment component, the pressure block presses the rapid adsorption mechanism and the disinfection dressing onto the wound. This allows the wound traction mechanism and the disinfection dressing to achieve a multi-dimensional hemostatic and sealing compression effect on the wound, with strong hemostatic ability, convenient operation, no need to tighten the compression around the limb, and strong targeting of the wound. At the same time, the coarse adjustment component and the fine adjustment component can easily loosen the pressure block, making it easy to observe the wound condition. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0022] In some embodiments, please refer to the accompanying drawings. Figures 1-7 A combat trauma emergency hemostasis and compression clamp includes a support plate 1 and a fixing strap 2 passing through both ends of the support plate 1; The support plate 1 is provided with buckles at both ends, so that the operator can easily adjust the length of the fixing strap 2 and fix the support plate 1 to the limbs of users of different body types. The upper end of the support plate 1 is fixed with a boss 3, and the lower end of the support plate 1 is fixedly installed with a disinfection dressing 4. The disinfection dressing 4 is used to directly contact the wound. By placing hemostatic and disinfecting drugs in the disinfection dressing 4, the wound is initially disinfected. An adjustable single-point pressing mechanism 5 is installed on the boss 3. The adjustable single-point pressing mechanism 5 includes a coarse adjustment component, a fine adjustment component, and a pressing block 55. The coarse adjustment component is installed on the boss 3, the fine adjustment component is installed inside the coarse adjustment component, and the pressing block 55 is installed inside the fine adjustment component. The support plate 1 is equipped with a rapid adsorption mechanism 7, which is located between the disinfectant dressing 4 and the pressure block 55. The rapid adsorption mechanism 7 is used to adsorb the blood flowing out of the wound to ensure a clear view around the wound. The support plate 1 is also equipped with a wound traction mechanism 6, which is used to pull the skin around the wound to reduce the size of the wound.

[0023] In this invention, after initial cleaning and disinfection of the wound, the support plate 1 is fixed to the wound using the fixing strap 2, and the pressure block 55 is aligned with the wound. Then, the wound traction mechanism 6 pulls the skin around the wound to reduce the wound size. The coarse adjustment component and the fine adjustment component work together to press the pressure block 55 onto the wound, so that the wound traction mechanism 6 and the disinfection dressing 4 work together to achieve a multi-dimensional hemostatic and sealing compression effect on the wound. The hemostatic ability is strong, the operation is relatively convenient, there is no need to tighten the compression around the limb, and the wound is highly targeted. At the same time, the pressure block 55 can be easily loosened by the coarse adjustment component and the fine adjustment component, making it easy to observe the wound condition.

[0024] The coarse adjustment assembly includes an outer sleeve 51 and an inner sleeve 52. A limiting groove 53 is provided on the boss 3. The outer sleeve 51 is rotatably connected to the boss 3 through a bearing. The inner wall of the outer sleeve 51 is threadedly connected to the outer wall of the inner sleeve 52, and the inner sleeve 52 is slidably connected to the limiting groove 53. The fine-tuning assembly includes a screw 54 and a connecting plate 56. The connecting plate 56 is fixedly connected to the inner wall of the inner sleeve 52, and the pressure block 55 is slidably connected to the inner wall of the inner sleeve 52. The lower end of the screw 54 is rotatably connected to the pressure block 55 through a bearing, and the upper end of the screw 54 is threadedly connected to the connecting plate 56. In this embodiment, the thread pitch between the outer sleeve 51 and the inner sleeve 52 is greater than the thread pitch between the screw 54 and the connecting plate 56. As a result, when the outer sleeve 51 and the screw 54 rotate in the same direction, the vertical displacement of the inner sleeve 52 is greater than the vertical displacement of the pressure block 55.

[0025] A pad is fixedly installed at the lower end of the pressure block 55. In this embodiment, the pad is selected as an air bag or a rubber block. In this invention, rotating the outer sleeve 51 can control the inner sleeve 52 to move vertically under the limiting action of the limiting through groove 53, and rotating the screw 54 can control the pressure block 55 to move vertically under the limiting action of the inner sleeve 52, so as to realize the rapid adjustment and fine adjustment of the position of the pressure block 55, which can not only meet the needs of rapid pressure hemostasis of the wound, but also achieve precise adjustment of the pressure force on the wound.

[0026] Multiple wound traction mechanisms 6 are provided. The multiple wound traction mechanisms 6 work together to pull the skin around the wound toward the wound to reduce the size of the wound, thereby achieving a multi-point traction effect on the wound and assisting in the hemostasis of the wound.

[0027] In this embodiment, at least two sets of wound traction mechanisms 6 are provided; The wound traction mechanism 6 includes a fixed column 61, a traction block 62, a connecting assembly 63, a take-up roller 64, a rotating shaft 65, a first knob 66, and a one-way rotation assembly. The rotating shaft 65 is rotatably connected to the wound traction mechanism 6 via a bearing. The take-up roller 64 is fixedly installed at the lower end of the rotating shaft 65, and the first knob 66 ​​is fixedly installed at the upper end of the rotating shaft 65. The fixed column 61 is fixedly connected to the support plate 1, and a pull rope is fixedly installed between the fixed column 61 and the take-up roller 64. The lower end of the traction block 62 is equipped with a connecting assembly 63 for fixing the traction block 62 to the skin. The traction block 62 is also equipped with a one-way rotation assembly for controlling the one-way rotation of the rotating shaft 65 to wind up the pull rope. In this embodiment, the connecting component 63 is a skin hook or adhesive.

[0028] The unidirectional rotation assembly includes a ratchet 67, a pawl 68, a connecting rod 69, a fixing block 610, and a spring 611. The ratchet 67 is fixedly connected to the rotation shaft 65, the fixing block 610 is fixedly connected to the pulling block 62, the connecting rod 69 is slidably connected to the fixing post 61, and the spring 611 is sleeved on the outside of the connecting rod 69. The two ends of the spring 611 are fixedly connected to the fixing block 610 and the connecting rod 69, respectively. The end of the connecting rod 69 is fixedly equipped with a pawl 68 that engages with the ratchet 67. In this invention, the traction block 62 is first fixed to the skin around the wound by the connecting component 63. Then, the rotating shaft 65 is rotated by the first knob 66, and the pull rope is gradually tightened on the take-up roller 64 by the ratchet 67 and the pawl 68. This causes the traction block 62 to push the skin around the wound toward the wound, thereby reducing the size of the wound and assisting in hemostasis.

[0029] The rapid adsorption mechanism 7 includes a bracket 71, an unwinding shaft 72, a rewinding shaft 73, an adsorption tourniquet 74, and a knob 75. Two brackets 71 are symmetrically fixedly installed on the front and rear sides of the support plate 1. The unwinding shaft 72 and the rewinding shaft 73 are rotatably mounted on the two brackets 71 respectively. The two ends of the adsorption tourniquet 74 are fixedly connected to the unwinding shaft 72 and the rewinding shaft 73 respectively, and the adsorption tourniquet 74 passes between the sterile dressing 4 and the pressure block 55. The end of the rewinding shaft 73 is fixedly connected to the knob 75. Damping is provided between the unwinding shaft 72 and the bracket 71, and between the rewinding shaft 73 and the bracket 71, to prevent the tourniquet 74 from becoming loose from the unwinding shaft 72 and the rewinding shaft 73, and at the same time to help maintain the tension of the tourniquet 74.

[0030] In this invention, the take-up shaft 73 is rotated by the knob 75, and the unwind shaft 72 and the take-up shaft 73 are controlled to perform take-up and unwind operations synchronously. The absorbent tourniquet 74 located between the disinfectant dressing 4 and the pressure block 55 is replaced, so as to always maintain the absorption effect on the blood at the wound site, ensure a clear field of vision around the wound, and facilitate observation.
