Description

Technical Field

[0001] This invention relates to the field of medical auxiliary device technology, specifically a wound cleaning device for maritime rescue. Background Technology

[0002] Wound irrigation or cleaning is a crucial step in wound treatment. When treating wounds on limbs, the limb is typically immobilized, and then a rinsing device or spray nozzle is used to spray disinfectant near the wound to clean it. A search revealed a wound cleaning device in Chinese patent publication number CN218652634U, comprising a base, telescopic rods evenly distributed on the top surface of the base, and a placement block disposed on the top surface of the telescopic rods. It also includes a first connecting plate connected to the side of the base, with an air inlet pipe extending through the side of the first connecting plate away from the base. The end of the air inlet pipe away from the first connecting plate is connected to an air pump, and a first connecting rod extends through one side of the first connecting plate.

[0003] In the aforementioned existing wound cleaning equipment, the patient's limb is first placed on a positioning block for restraint, and then disinfectant is sprayed onto the wound through a nozzle to clean it. Since there are many types of wounds, when rinsing deeper wounds, relying on the nozzle to spray disinfectant onto the wound cannot clean the inside of the wound. Therefore, medical staff usually need to open the wound to expose it before rinsing. This method is inconvenient to operate, especially since a single medical staff member cannot rinse the wound while opening it, resulting in low rinsing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a wound cleaning device for maritime rescue, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wound cleaning device for maritime rescue, comprising:

[0006] An upper clamping seat is hinged to a lower clamping seat, and each of the upper and lower clamping seats has an arc-shaped clamping opening at its opposite end;

[0007] The tubular part is fixed to the upper clamping seat, and the end away from the upper clamping seat is detachably connected to a liquid medicine tank;

[0008] Two actuating blocks are provided and slidably connected to the upper clamping seat. The actuating blocks can rotate freely within the upper clamping seat along the axial direction of the clamping opening.

[0009] A spray section is installed on the tubular section and is connected to the tubular section in a through manner;

[0010] The disengaging unit is located on the upper clamping seat and is used to drive the two disengaging blocks to move in a direction that is relatively far apart.

[0011] With the above technical solution, when the lower clamping seat and the upper clamping seat rotate until the two clamping ports merge into a circular hole, the limb can be fixed and limited. The two actuating blocks are driven by the opening unit to move in opposite directions, so that the two actuating blocks can generate two opposite pulling forces on the deeper wound, so that the wound can be opened to expose the inside of the wound, which is convenient for disinfectant to disinfect the deeper part of the wound, and is convenient for single-person operation.

[0012] Furthermore, a soft pouch is fixed to the side of the actuating block facing the inside of the clamping opening.

[0013] By using the above technical solution, a soft capsule is provided so that when the agitator comes into contact with the patient's skin, the coefficient of friction between the soft capsule and the skin is relatively large, which allows the soft capsule to smoothly open the wound when the agitator moves.

[0014] Furthermore, the cross-section of the actuating block is narrower at the top and wider at the bottom, and the upper clamping seat has an arc-shaped slot for the actuating block to engage and slide freely.

[0015] Through the above technical solution, the actuating block slides in the arc-shaped slot, thereby enabling the actuating block to rotate along the axial direction of the clamping opening.

[0016] Furthermore, the liquid medicine tank is provided with a compressed gas inlet, and the compressed gas inlet is equipped with a pressure regulating valve.

[0017] Through the above technical solution, external compressed gas enters the medicine tank through the compressed gas inlet, which drives the disinfectant in the medicine tank, thereby enabling the disinfectant to quickly enter the tubular part. In addition, by setting a pressure regulating valve, the flow rate of compressed gas entering the medicine tank can be adjusted.

[0018] Furthermore, the lower clamping seat is provided with a waste liquid collection tank, which is in communication with the clamping opening.

[0019] Through the above technical solution, the disinfectant solution after rinsing can flow into the waste liquid collection tank for subsequent collection.

[0020] Furthermore, the upper clamping seat and the lower clamping seat are provided with extensions made of silicone material, which extend from the edge of the clamping opening toward the outside of the clamping opening.

[0021] Through the above technical solution, the extension part enables the contact surface between the inner wall of the clamping mouth and the skin to a certain extent after the upper and lower clamping seats clamp the limb, reducing the leakage of disinfectant from the gap between the skin and the inner wall of the clamping mouth.

[0022] Furthermore, the disengaging unit includes a sliding ring slidably fitted around the periphery of the tubular portion, the upper clamping seat is rotatably connected to two gears via a mounting shaft, the outer arc surface of the disengaging block is provided with toothed portions, the two gears respectively mesh with the two toothed portions for transmission, a rotating arm is fixedly sleeved at the end of the rotating shaft, a hinge rod is rotatably connected around the periphery of the sliding ring, and the lower end of the hinge rod is rotatably connected to the rotating arm respectively.

[0023] With the above technical solution, when the sliding ring slides downward on the periphery of the tubular part, the hinge rod will drive the rotating arm to swing, and the rotating arm will drive the rotating shaft to rotate. When the rotating shaft rotates, the gear will mesh with the toothed part to drive the agitator to rotate along the axial direction of the clamping opening, and the two agitators will move in a direction away from each other, so that the two agitators can open the wound and expose the deep part of the wound for easy rinsing.

[0024] Furthermore, an adjusting ring is threadedly fitted around the periphery of the tubular portion, with the lower end face of the adjusting ring abutting against the upper end face of the sliding ring. A spring is wound around the periphery of the tubular portion, with both ends of the spring elastically abutting against the sliding ring and the upper clamping seat, respectively, in the direction of the spring force.

[0025] Through the above technical solution, the rotating adjusting ring is screwed into the circumferential thread of the tubular part, thereby generating a downward thrust on the sliding ring, which allows the sliding ring to move downward. When the sliding ring moves downward, it will cause the hinge rod to drive the rotating arm to swing, and the spring is in a compressed state and accumulates elastic potential energy. Then, when the adjusting ring rotates in the opposite direction, the elastic potential energy of the spring is released, allowing the sliding ring to move upward and reset.

[0026] Furthermore, a fixing part is fixedly connected to the inner cavity of the tubular part, and a rotating part is rotatably embedded in the fixing part. The spraying part is fixedly connected to the rotating part, and the rotating part has a liquid inlet that communicates with the inner cavity of the spraying part.

[0027] A hollow frame is fixedly connected to the inner cavity of the liquid inlet. A swing rod is slidably inserted through the hollow frame. A connecting rod is hinged to the upper end of the swing rod. A connecting part is fixedly connected to the inner wall of the sliding ring. A sealing sleeve is coaxially and slidably engaged in the inner cavity of the tubular part. The periphery of the sealing sleeve is fixedly connected to the connecting part. The tubular part has an oblong hole for the connecting part to pass freely. The sealing sleeve is used to close the oblong hole.

[0028] With the above technical solution, when the sliding ring moves downward, the connecting rod will drive the swing rod to swing, which in turn will drive the rotating part to rotate. When the rotating part rotates, it will simultaneously drive the spraying part to rotate, so that the spraying part can swing along the length of the wound, thereby enabling the rinsing of longer wounds and reducing the rinsing blind spots.

[0029] Furthermore, the fixing part has a spherical groove, and the rotating part is engaged with the spherical groove and can rotate in all directions.

[0030] Through the above technical solution, the rotating part is engaged in the spherical groove and rotates in all directions, so that the rotating part is rotatably connected to the fixed part.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. In this invention, when the lower clamping seat and the upper clamping seat rotate to the point where the two clamping openings merge into a circular hole, the limb can be fixed and limited. The two actuating blocks are driven by the opening unit to move in opposite directions, thereby enabling the two actuating blocks to generate two opposite pulling forces on the deeper wound, so that the wound can be opened to expose the inside of the wound, making it easier for disinfectant to disinfect the deeper part of the wound, and making it easy for a single person to operate.

[0033] 2. In this invention, when the sliding ring slides downward around the periphery of the tubular part, it will cause the hinge rod to drive the rotating arm to swing, and the rotating arm to drive the rotating shaft to rotate. When the rotating shaft rotates, the gear will mesh with the toothed part to drive the agitator to rotate along the axial direction of the clamping opening, and the two agitators will move in a direction away from each other, so that the two agitators can open the wound and expose the deep part of the wound for easy rinsing.

[0034] 3. In this invention, when the sliding ring moves downward, the connecting rod will cause the swing rod to swing, which in turn causes the swing rod to drive the rotating part to rotate. When the rotating part rotates, it simultaneously drives the spraying part to rotate, so that the spraying part can swing along the length of the wound, thereby enabling the longer wound to be rinsed and reducing the rinsing blind spot.

[0048] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Please see Figures 1-12This invention provides a technical solution: a wound cleaning device for maritime rescue, comprising an upper clamping seat 9, with a lower clamping seat 11 hinged to one end of the upper clamping seat 9. Each of the upper clamping seat 9 and the lower clamping seat 11 has an arc-shaped clamping opening 10 at its opposite ends. When the upper clamping seat 9 and the lower clamping seat 11 rotate along their hinge until their opposite ends abut, the two clamping openings 10 merge into a complete circular hole structure. Furthermore, the walls of the upper clamping seat 9 and the lower clamping seat 11 have extensions extending outwards from the clamping openings 10. The extensions can be made of silicone and can be chemically treated. The device is installed on the upper clamping seat 9 and the lower clamping seat 11 by means of a method (such as adhesive bonding). A tubular part 20 is vertically fixed to the side wall of the upper clamping seat 9 away from the lower clamping seat 11. The tubular part 20 is hollow inside, and a medicine tank 2 is installed at the end of the tubular part 20 away from the upper clamping seat 9 by means of a thread. The medicine tank 2 is filled with a suitable disinfectant. In addition, a compressed gas inlet is provided at the end of the medicine tank 2 away from the upper clamping seat 9. The compressed gas inlet is connected to an external compressed gas delivery pump through a pipeline. In addition, a pressure regulating valve 1 is installed at the compressed gas inlet to regulate the air intake of the compressed gas inlet.

[0050] The lower clamping seat 11 has a waste liquid collection tank 12, which communicates with the clamping opening 10. The upper clamping seat 9 has an arc-shaped groove 18, in which two actuating blocks 15 are engaged. The outer contour of the actuating blocks 15 is arc-shaped and narrower at the top and wider at the bottom. The actuating blocks 15 can rotate freely along the axial direction of the clamping opening 10 within the arc-shaped groove 18. A soft pouch 16 is fixed to the side of the actuating blocks 15 facing the inside of the clamping opening 10. The outer arc surfaces of the two actuating blocks 15 have toothed portions 22. The upper clamping seat 9 has two mounting cavities, in which gears 5 are installed. The shaft 6 is rotatably connected to the upper clamping seat 9. Two gears 5 mesh with two toothed parts 22 respectively. A sliding ring 4 is slidably fitted around the periphery of the tubular part 20. A rotating arm 8 is fixedly fitted at the end of the shaft 6. A hinge rod 7 is rotatably connected around the periphery of the sliding ring 4. The lower ends of the hinge rod 7 are rotatably connected to the rotating arm 8 respectively. An adjusting ring 3 is threadedly fitted around the periphery of the tubular part 20. The lower end face of the adjusting ring 3 abuts against the upper end face of the sliding ring 4. A spring 13 is wound around the periphery of the tubular part 20. The two ends of the spring 13 elastically abut against the sliding ring 4 and the upper clamping seat 9 respectively in the direction of the elastic force.

[0051] A fixing part 17 is fixedly connected to the inner cavity of the tubular part 20. A rotating part 25 is rotatably embedded in the fixing part 17. Specifically, the fixing part 17 has a spherical groove 34. The rotating part 25 engages with the spherical groove 34 and rotates omnidirectionally. The rotating part 25 rotates omnidirectionally within the spherical groove 34, so that the rotating part 25 is omnidirectionally connected to the fixing part 17. A tubular spray part 14 is fixedly connected to the wall of the rotating part 25. The end of the spray part 14 away from the rotating part 25 extends to the arc-shaped groove 18 and communicates with the clamping port 10 of the upper clamping seat 9. The upper clamping seat 9 has a receiving cavity for the spray part 14 to pass freely and communicates with the tubular part 20. The receiving cavity and the clamping port 10 In a connected state, the rotating part 25 has an inlet 26 that communicates with the inner cavity of the spraying part 14. A hollow frame 27 is fixedly connected to the inner cavity of the inlet 26. A swing rod 24 is slidably passed through the hollow frame 27. A connecting rod 19 is hinged to the upper end of the swing rod 24. A connecting part 23 is fixedly connected to the inner wall of the sliding ring 4. A sealing sleeve 35 is coaxially and slidably engaged in the inner cavity of the tubular part 20. The periphery of the sealing sleeve 35 is fixedly connected to the connecting part 23. The tubular part 20 has an oblong hole 21 for the connecting part 23 to pass freely. The sealing sleeve 35 is used to close the oblong hole 21, so that the disinfectant in the tubular part 20 is blocked by the sealing sleeve 35, so that the disinfectant will not leak out from the oblong hole 21.

[0052] Furthermore, a fixed sealing part 29 is fixedly installed at the lower end of the spray section 14. A connecting groove 32 is provided on the end face of the fixed sealing part 29, and multiple small spray holes 30 are also provided on the end face of the fixed sealing part 29. A rotating sealing part 28 is coaxially and slidably engaged within the inner cavity of the spray section 14. The lower end face of the rotating sealing part 28 slides in contact with the upper end face of the fixed sealing part 29. A first connecting port 33 and a second connecting port 31 are provided on the end face of the rotating sealing part 28. Additionally, a driven gear (not shown in the figure) is fixedly sleeved around the periphery of the spray section 14. An arc-shaped rack (not shown in the figure) is fixedly connected to the inner wall of the receiving cavity. The arc-shaped rack and the driven gear are meshed. Thus, when the swing rod 24 drives the rotating part 25 to swing within the spherical groove 34, the driven gear and the arc-shaped rack will mesh and transmit power. Since the rotating part 25 can rotate freely within the spherical groove 34, the driven gear will rotate, driving the rotating part 25 to rotate. Simultaneously, the fixed sealing part 29 will rotate. When the fixed sealing part 29 rotates, the first connecting port 33, which was originally connected to the connecting groove 32, will rotate to a state that is offset from the connecting groove 32. The second connecting port 31, which was originally offset from the small spray hole 30, will rotate to connect with the small spray hole 30. This changes the way the disinfectant is sprayed from the first fluid path formed by the connecting groove 32 and the first connecting port 33 to the second fluid path formed by the second connecting port 31 and the small spray hole 30. This reduces the spray range of the disinfectant and allows it to be sprayed towards a more concentrated area. When the disinfectant is sprayed along the first fluid path onto the surface of the patient's wound, since there is residual blood and foreign matter on the skin surface of the wound, the large-scale spray can wash away the residual blood and foreign matter. When the wound is more exposed, the spray range of the disinfectant becomes more concentrated, and the disinfectant can effectively rinse the inside of the wound.

[0053] Working principle of the invention:

[0054] Place the lower clamp 11 on an external table or other platform. Insert the patient's limb into the clamping port 10 of the lower clamp 11. Then flip the upper clamp 9 so that the upper clamp 9 and the lower clamp 11 are in a combined state. Furthermore, Velcro can be installed on the side of the upper clamp 9 and the lower clamp 11 away from the hinge. This allows the upper clamp 9 and the lower clamp 11 to be securely installed together after they are combined, preventing them from becoming loose. After the limb is fixed, try to ensure that the wound on the limb is directly below the medicine container 2.

[0055] The external compressed gas delivery pump is started, and the compressed gas delivery pump delivers compressed gas to the compressed gas inlet, which in turn can generate pressure on the disinfectant in the medicine tank 2, so that the disinfectant can enter the tubular part 20 from the medicine tank 2. The medical staff can rotate the adjusting ring 3 with one hand, and the adjusting ring 3 is screwed into the circumference of the tubular part 20, so that the lower end of the adjusting ring 3 exerts downward pressure on the sliding ring 4, which in turn causes the sliding ring 4 to move downward and compress the spring 13, and the spring 13 begins to accumulate elastic potential energy.

[0056] When the sliding ring 4 moves downward, the hinge rod 7 will cause the rotating arm 8 to swing, and the rotating arm 8 will cause the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, the gear 5 will mesh with the toothed part 22, thereby driving the actuating block 15 to rotate along the axial direction of the clamping opening 10, and causing the two actuating blocks 15 to move in a direction away from each other, so that the soft pouches 16 on the two actuating blocks 15 can open the wound (the two soft pouches 16 are located on both sides of the wound), thereby exposing the depth of the wound.

[0057] Disinfectant is sprayed onto the wound through the tubular section 20 and the spray section 14 to rinse the wound. Additionally, when the swing rod 24 drives the rotating section 25 to swing within the spherical groove 34, the driven gear and the arc-shaped rack mesh. Since the rotating section 25 can rotate freely within the spherical groove 34, the driven gear will rotate, driving the rotating section 25 to rotate. When the rotating section 25 rotates, it synchronously drives the fixed sealing section 29 to rotate. When the fixed sealing section 29 rotates, the first connecting port 33, which was originally connected to the connecting groove 32, rotates to a position offset from the connecting groove 32, and the second connecting port 31, which was originally offset from the small spray hole 30, will... Rotate to connect with the small spray hole 30, so that the disinfectant is sprayed out through the first fluid path formed by the connecting groove 32 and the first connecting port 33, and then through the second fluid path formed by the second connecting port 31 and the small spray hole 30. This reduces the spray range of the disinfectant and allows it to be sprayed to a more concentrated area. When the disinfectant is sprayed along the first fluid path onto the surface of the patient's wound, since there is residual blood and foreign matter on the skin surface of the wound, the large-scale spray can wash away the residual blood and foreign matter. When the wound is more exposed, the spray range of the disinfectant becomes more concentrated, and the disinfectant can effectively rinse the inside of the wound.

[0058] Furthermore, a one-way valve (not shown in the figure) is installed at the outlet of the medicine tank 2. Only when compressed gas squeezes the disinfectant in the medicine tank 2 will the pressure of the disinfectant be greater, thereby opening the one-way valve and allowing the disinfectant to enter the tubular part 20 from the medicine tank 2. In addition, a heating device can be installed on the outer wall of the medicine tank 2 to heat the disinfectant in the medicine tank 2 and prevent the low temperature of the disinfectant from irritating the patient in cold weather.
