Detailed Implementation

[0032] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a full understanding of the implementation of embodiments of the present invention.

[0033] Existing wound care devices typically consist of a main support structure, an integrated pump, piping, a reservoir, and a control module. The main structure is usually made of stainless steel or heavy-duty engineering plastics. The integrated pump and piping deliver the irrigation fluid, while the reservoir stores the fluid and is typically large in capacity. The control module includes an interface and sensors for adjusting irrigation parameters. This necessitates the use of dedicated supports or mobile carts for portability. Consequently, conventional wound irrigation devices are generally bulky and heavy, making them difficult to move and carry in practice. This significantly limits their application scenarios and scope, reducing their practicality and convenience.

[0034] To solve the above problems, refer to Figures 1-4 As shown, this embodiment provides a wound irrigation and care device, mainly comprising a fixing box 1. The fixing box 1 serves as the main structure of the entire device, with vertically extending mounting grooves 2 symmetrically formed on both sides. The inner wall of the mounting groove 2 is slidably connected to a support column 3, allowing the support column 3 to reciprocate up and down within the mounting groove 2. An upwardly extending arc-shaped support bracket 4 is fixedly connected to the top of the support column 3 for supporting the patient's limb.

[0035] A groove 5 is provided on the front top of the fixed box 1, and a filter plate 6 is embedded in the groove 5. The filter plate 6 is a multi-layer stepped metal filter plate, which can effectively filter impurities generated during the rinsing process. A fixing groove 7 is provided on the rear top of the fixed box 1. A liquid storage tank 8 and a water pump 9 are fixedly installed side by side in the fixing groove 7, with the liquid storage tank 8 located to the left of the water pump 9. The water inlet of the water pump 9 is connected to the bottom of the liquid storage tank 8 through a water supply pipe 10, and the water outlet is connected to a downward-extending hose 11. The end of the hose 11 is connected to a spray head 12 for rinsing the wound. In addition, a rotatable connecting ring 15 is provided in the middle of the outer surface on both sides of the fixed box 1 for easy carrying of the device.

[0036] The fixed box 1, serving as the foundation of the entire device, not only supports all other components but also provides sliding tracks for the support column 3 via mounting grooves 2 on both sides. The support column 3 and the arc-shaped support bracket 4 together form a limb support system, capable of adjusting height according to different patient positions and wound locations, ensuring a stable rinsing posture for the patient's limb. The groove 5 and filter plate 6 constitute a waste fluid collection and treatment system. Waste fluid generated during rinsing first flows into the groove 5, and after being filtered layer by layer by the filter plate 6, impurities are effectively intercepted, ensuring the cleanliness of the waste fluid. The storage tank 8 stores the rinsing fluid, while the water pump 9 pumps the rinsing fluid to the spray head 12, achieving automatic delivery and spraying of the rinsing fluid. The design of the connecting ring 15 makes the entire device easy to handle and carry, allowing for easy transport in hospital transfers or emergency situations, improving the device's flexibility.

[0037] In use, first adjust the height of the support column 3 according to the patient's position and wound location. After the support column 3 slides into the appropriate position in the mounting groove 2, the patient's limb is placed on the arc-shaped support 4. Then, start the water pump 9, and the rinsing fluid is delivered from the storage tank 8 through the water pipe 10 and hose 11 to the spray head 12, which rinses the wound. Waste fluid generated during rinsing flows into the groove 5, is filtered by the filter plate 6, and is discharged from the waste outlet 13 of the fixed box 1.

[0038] This embodiment solves the problem of existing wound irrigation and care devices being bulky and difficult to transport. By integrating all components into a fixed box 1, the entire device is compact, easy to transport and carry, expanding its application scenarios and scope. Meanwhile, the height-adjustable design of the support column 3 and the arc-shaped support bracket 4 allows the device to adapt to different patient positions and wound locations, improving its applicability. Furthermore, the filter plate 6 effectively intercepts impurities generated during irrigation, ensuring the cleanliness of the waste liquid and reducing the risk of cross-infection.

[0039] The wound irrigation and care device provided in this embodiment achieves a high degree of integration and compactness, effectively solving the problems of large size and difficult transportation of traditional devices. This makes the device lighter and easier for medical staff to carry and use in various environments, expanding its application scenarios and scope, and improving its practicality and flexibility. Furthermore, this device achieves stable support for the patient's limb and effective filtration of waste fluid through a limb support system and a waste fluid collection and treatment system. The height-adjustable design of the limb support system allows the device to adapt to different patient positions and wound locations, improving the accuracy and comfort of irrigation care. The waste fluid collection and treatment system effectively intercepts impurities generated during irrigation, ensuring the cleanliness of the waste fluid, reducing the risk of cross-infection, and providing strong protection for patient safety.

[0040] In some embodiments of this application, a limiting rod 23 is fixed at the end of the support column 3 away from the arc-shaped support bracket 4, and the limiting rod 23 extends away from the support column 3. At the same time, limiting grooves 22 are formed on both sides of the inner wall of the mounting groove 2, and the limiting rod 23 is slidably connected to the limiting grooves 22.

[0041] The limiting rod 23 and the limiting groove 22 together constitute the sliding limiting system of the support column 3. The limiting rod 23 slides synchronously within the limiting groove 22 as the support column 3 slides, effectively limiting the sliding range of the support column 3 and preventing the support column 3 from extending or retracting excessively, thereby ensuring the stability and safety of the support column 3.

[0042] This embodiment solves the problem of the support column 3 potentially extending or retracting excessively during sliding. Through the cooperation of the limiting rod 23 and the limiting groove 22, the sliding range of the support column 3 is effectively limited, preventing instability or safety hazards caused by excessive sliding. This not only improves the safety of the device but also enhances its overall stability and reliability.

[0043] In some embodiments of this application, connecting plates are provided on both sides of the mounting groove 2 of the fixed box 1, and threaded holes are evenly distributed along the axial direction on the connecting plates. Each threaded hole is provided with a positioning rod 21, which can be fixed to the threaded hole by threaded connection. At the same time, positioning holes are evenly distributed along the axial direction on the surface of the support column 3, and the positioning holes are threaded to the ends of the positioning rods 21.

[0044] The positioning rod 21 and the positioning hole facilitate the height adjustment and fixation of the support column 3. By loosening the positioning rod 21, the support column 3 can be slid to the desired height; then, tightening the positioning rod 21 will thread the end of the positioning rod 21 into the positioning hole on the support column 3, thereby fixing the support column 3 at the desired height.

[0045] This embodiment solves the problem of fixed height and poor adaptability of the support column 3. Through the cooperation of the positioning rod 21 and the positioning hole, the height of the support column 3 can be adjusted and fixed, allowing the device to adapt to different patient positions and wound locations, thus improving its applicability. At the same time, this height adjustment and fixing method is simple and convenient to operate, improving the ease of use of the device.

[0046] In some embodiments of this application, the bottom of the fixing box 1 is provided with a rectangular support base 14. The bottom surface of the support base 14 is coated with a rubber anti-slip pad to increase the friction between it and the placement surface. At the same time, the four corners of the support base 14 are provided with downward protruding positioning bosses to facilitate the positioning of the device.

[0047] The support base 14 provides a stable foundation for the entire device, capable of bearing its full weight. The rubber anti-slip pad increases friction between the support base 14 and the placement surface, preventing the device from sliding or tipping over due to external forces during use. The positioning boss facilitates the device's positioning on the placement surface, ensuring stable placement in the designated location.

[0048] In conjunction with the foregoing embodiments, during use, medical staff can accurately adjust the height of the wound irrigation and care device to suit the needs of different patients. Firstly, by sliding the support column 3 and fixing it with the positioning rod 21, the height of the arc-shaped support bracket 4 can be further adjusted to ensure that the patient's limb is placed comfortably and stably. This helps medical staff to more accurately locate the wound, thereby providing more effective irrigation and care.

[0049] Simultaneously, after the water pump 9 is activated, the rinsing fluid is automatically drawn from the storage tank 8 and evenly sprayed onto the wound through the spray head 12. This automated process not only reduces the workload of medical staff but also ensures the uniformity and consistency of rinsing, helping to improve the rinsing effect. Through the cooperation of the limiting rod 23 and the limiting groove 22, as well as the structural design of the positioning rod 21 and the positioning hole, the device can adapt to different patient positions and wound locations.

[0050] In summary, the wound irrigation and care device provided in this embodiment is simple and quick to use, and has significant beneficial effects. This device not only improves the efficiency and safety of irrigation care, but also provides patients with a more comfortable and convenient irrigation care experience.

[0051] In some embodiments of this application, a fixed cover 16 is connected to the top of the fixed box 1. The fixed cover 16 is rotatably connected to the fixed box 1, and can be rotated to open or close around the top edge of the fixed box 1. A handle is provided on the top surface of the fixed cover 16 to facilitate the user to open and close the fixed cover 16. At the same time, a magnetic stone 17 is provided on the bottom surface of the fixed cover 16, and an iron piece 18 is fixedly installed on the top of the fixed box 1 at the position corresponding to the magnetic stone 17.

[0052] Understandably, the fixed cover 16 serves to protect the internal components of the enclosure when the device is not in use, preventing dust, debris, and other contaminants from entering. The handle facilitates the user's opening and closing of the fixed cover 16. When using the device, the user can open the enclosure 1 by grasping the handle, lifting it upwards, and rotating the fixed cover 16.

[0053] The magnet 17 and the iron plate 18 work together to ensure that the fixing cover 16 fits tightly against the fixing box 1 when closed, thus guaranteeing the airtightness of the fixing cover 16. After the device is used, the fixing cover 16 is rotated to the top of the fixing box 1, and the magnet 17 and the iron plate 18 automatically attract each other, making the fixing cover 16 fit tightly against the fixing box 1, thus closing the fixing box 1.

[0054] This embodiment solves the problems of easily damaged internal components and poor sealing performance of the fixing cover 16. The fixing cover 16 protects the internal components from dust, debris, and other contaminants. Simultaneously, the cooperation of the magnet 17 and the iron plate 18 ensures that the fixing cover 16 fits tightly against the fixed box 1 when closed, improving the sealing performance of the fixing cover 16 and further protecting the safety and cleanliness of the internal components.

[0055] In some embodiments of this application, a slot 19 is provided on the side of the mounting box 1. The slot 19 is designed to allow the battery 20 to be inserted and fixed therein, ensuring a stable connection. The battery 20 is embedded in the slot 19, is detachable and plugs in, and is electrically connected to the water pump 9 via wires.

[0056] The battery 20, acting as an independent power module, provides continuous power to the water pump 9 and other components that may require electricity. This design allows the entire unit to operate without relying on an external power source, enhancing its independence and flexibility. A reliable electrical connection is established between the battery 20 and the water pump 9 via dedicated wiring, ensuring stable and efficient power transmission to the water pump 9 to drive its normal operation.

[0057] The inclusion of battery 20 allows the device to continue operating in environments without external power, thus expanding its application scenarios and scope. Whether in outdoor operations, temporary construction sites, or remote areas, the device can function normally as long as battery 20 has sufficient charge. Furthermore, the removable design of battery 20 simplifies the battery replacement and charging process; users can easily remove the old battery for charging or replace it with a new one, ensuring the device's continuous operation and practicality.

[0058] In some embodiments of this application, a silicone protective pad is adhered to the inner arc surface of the arc-shaped support bracket 4. Additionally, elastic fixing straps are provided at both ends of the top of the arc-shaped support bracket 4, and these elastic fixing straps are detachably connected to the arc-shaped support bracket 4.

[0059] The silicone protective pad improves patient limb comfort and reduces direct contact between the limb and the curved support 4, preventing pressure sores and other problems caused by prolonged contact. The elastic fixation strap secures the patient's limb to the curved support 4, preventing limb movement during rinsing and ensuring the accuracy and safety of the rinsing procedure.

[0060] When using the device, place the patient's limb on the curved support 4, with the silicone protective pad contacting the limb for increased comfort. Then, wrap the elastic strap around the limb and secure it to the curved support 4, firmly fixing the limb in place. This prevents limb movement during rinsing from affecting the rinsing effect.

[0061] In some embodiments of this application, the liquid storage tank 8 has a threaded inlet 24 on the top right side. The inlet 24 is designed with internal threads to match a threaded closure plug. The closure plug is inserted into the inlet 24 to seal it when not in use, preventing external impurities from entering.

[0062] The main function of the inlet 24 is to add flushing fluid to the reservoir 8. When flushing fluid needs to be added, the user can unscrew the sealing plug and pour the flushing fluid directly into the reservoir 8 through the inlet 24. After adding, the sealing plug is tightened again to ensure the inlet 24 is sealed, thereby preventing accidental leakage of flushing fluid and avoiding pollution to the environment and equipment.

[0063] In some embodiments of this application, a waste outlet 13 is provided at the lower part of the fixed box 1. This waste outlet 13 is connected to the bottom of the groove 5, ensuring that the waste liquid generated during the rinsing process can flow smoothly from the groove 5 into the waste outlet 13. In order to close the waste outlet 13 when drainage is not required and prevent waste liquid leakage, a rubber sealing plug is inserted into the waste outlet 13. The size of the rubber sealing plug matches the waste outlet 13 to ensure a sealing effect.

[0064] The design of the waste outlet 13 simplifies the waste liquid discharge process. Users simply need to pull out the rubber sealing plug, and the waste liquid can be smoothly discharged through the waste outlet 13. At the same time, the sealing performance of the rubber sealing plug effectively prevents leakage of waste liquid when it is not needed, thereby protecting the environment from pollution.

[0065] In some embodiments of this application, the end of the hose 11 is provided with a quick-release connector. The spray head 12 is detachably connected to the hose 11 via this quick-release connector. The design of the quick-release connector makes the connection between the spray head 12 and the hose 11 simpler and faster, and can be completed without the use of tools. When it is necessary to replace or clean the spray head 12, the user only needs to loosen the quick-release connector to easily remove the spray head 12. This not only improves the flexibility and practicality of the device, but also simplifies the replacement and cleaning process of the spray head 12, ensuring the cleanliness and hygiene of the spray head 12.

[0066] As can be seen from the above embodiments, the working steps of the wound irrigation and care device of this application are as follows:

[0067] First, hold the connecting ring 15 and carry the device to a suitable position. Then, using the rotation of the connecting ring 15 on the surface of the fixed box 1, rotate the connecting ring 15 to both sides of the fixed box 1. Hold the handle to separate the magnet 17 from the iron plate 18 and open the fixed cover 16. Next, according to the patient's position and the location of the wound, loosen the positioning rod 21, slide the support column 3 to a suitable height, and adjust the height of the support support 4 to a suitable position. Then, screw the positioning rod 21 into the positioning hole of the support column 3 to fix the support column 3. Then, place the patient's limb on the support support 4 and fix the limb with the elastic band to prevent shaking during the rinsing process. Then, start the water pump 9, which will pump the stored liquid... Water in tank 8 is delivered to hose 11 through water pipe 10, and then sprayed out by nozzle 12 at the end of hose 11 to rinse the wound. At the same time, nozzle 12 can be flexibly adjusted in position and angle to aim at the wound for thorough rinsing. Waste liquid after rinsing the wound falls into groove 5 and is filtered by filter plate 6. Impurities are intercepted and the filtered waste liquid remains in groove 5. When it is necessary to drain the waste liquid, pull out the sealing plug of outlet 13 to drain the waste liquid. After draining, insert the sealing plug again. After rinsing is completed, turn off water pump 9, put nozzle 12 back into fixed box 1, close fixed cover 16, and magnet 17 and iron sheet 18 are attracted to each other, so that fixed cover 16 is tightly attached to fixed box 1.

[0068] In summary, the device of this application is highly integrated, compact in structure, and easy to transport and carry. Through the limb support system and waste fluid collection and treatment system, it achieves stable support for the patient's limb and effective filtration of waste fluid. Furthermore, it features easy maintenance and cleaning, and adjustable irrigation fluid types, further enhancing its practicality and flexibility. Therefore, the wound irrigation and care device of this application has broad application prospects and promotional value in the medical field.
