Abstract
Description
Technical Field
[0001] This invention relates to the field of neurosurgical nursing technology, specifically a wound cleaning device for neurosurgical nursing. Background Technology
[0002] Neurosurgical wound cleaning devices are specialized instruments used in the care of various neurosurgical wounds, including postoperative wounds, traumatic brain injury wounds, skull defect repair incisions, cerebrovascular interventional puncture wounds, and scalp surgical sutures. Primarily used for rinsing and cleaning wound surfaces, these devices provide controllable rinsing power to deliver sterile saline, rinsing solutions, and other nursing fluids. Through the accompanying tubing and nozzle structure, the rinsing fluid is applied to the wound surface and interior, effectively flushing away blood clots, tissue exudate, necrotic tissue fragments, and contaminants. Simultaneously, they can facilitate the local infiltration and administration of medications to the wound. These devices are core instruments for wound cleaning in routine neurosurgical wound care, dressing changes, and infection control procedures.
[0003] In existing technologies, all cleaning nozzles are integrated fixed nozzles. Fixed nozzles do not have the ability to adjust the diameter and shape. Clinically, various special nozzles of different specifications need to be equipped for different wound types and different healing stages. During the operation, for the cleaning needs of different wounds on the same patient or different areas of the same wound, the nozzles need to be repeatedly disassembled and replaced. This not only increases the operation steps and prolongs the nursing time, but also increases the risk of instrument contamination and cross-infection due to frequent disassembly and assembly of instruments. Summary of the Invention
[0004] To address the problems in the prior art, the present invention provides a wound cleaning device for neurosurgical care.
[0005] The technical solution adopted by the present invention to solve its technical problem is: a wound cleaning device for neurosurgical care, comprising a tube body, wherein a spraying mechanism is provided on the tube body; The bottom end of the tube is provided with an adjustment mechanism, which includes a support ring, a deformation ring, a connecting port and an isolation layer. The deformation ring is provided with multiple connecting grooves, and each connecting groove is movably engaged with a limit wire. A positioning ring is threaded onto the connection port, and a positioning pad is fixedly connected to the top of the positioning ring. The isolation layer has a placement groove inside, in which clay is movably placed. The outer wall of the isolation layer is fixedly connected with an anti-slip texture.
[0006] Specifically, the spraying mechanism includes a moving rod, an inlet and outlet, and two lever plates. A piston is fixedly connected to the bottom end of the moving rod, and a pressing plate is fixedly connected to the top end of the moving rod.
[0007] Specifically, the moving rod is slidably connected to the top wall of the pipe body, and the bottom end of the moving rod slides through the top wall of the pipe body and is fixedly connected to the piston. The inlet and outlet are opened at the center of the bottom end of the pipe body, and the inlet and outlet are in a through state with the pipe body. The lever plate is symmetrically fixedly connected to the pipe body near the top end. A sealing gasket is provided at the connection between the pipe body and the moving rod.
[0008] Specifically, the support ring is fixedly connected at the bottom end of the pipe corresponding to the inlet and outlet positions, and the diameter of the support ring is larger than the diameter of the inlet and outlet. The deformable ring is fixedly connected at the bottom end of the pipe corresponding to the outer ring of the support ring, and the deformable ring is made of medical liquid silicone. The inner ring of the deformable ring abuts against the outer ring of the support ring.
[0009] Specifically, the connection port is fixedly connected to the outer ring of the deformation ring at the bottom of the tube body. The connection port is annular. The top of the isolation layer is turned outward and abuts against the top of the positioning pad. The isolation layer is located between the deformation ring and the positioning ring.
[0010] Specifically, the limiting wire is made of medical-grade ultra-fine elastic stainless steel wire, multiple levers arranged in an array are fixedly connected to the outer wall of the positioning ring, the positioning pad is made of rubber, and the isolation layer is flexible.
[0011] The beneficial effects of this invention are: Adaptable to various wound shapes, no nozzle replacement is required. Through the sculpting of clay and the coordinated deformation of the deformation ring, the nozzle diameter and water flow shape can be flexibly adjusted, such as flat, slit, and columnar shapes, to suit different types of neurosurgical wounds. This solves the problem of frequent replacement and poor adaptability of existing fixed nozzles. The nozzle shape can be adjusted simply by manually kneading the isolation layer. The non-slip texture improves operational stability. It does not rely on the experience and skills of nursing staff, lowering the operation threshold and achieving standardized cleaning. In addition, the limiting wire and clay work together to lock the shape with the plasticity of the clay, and the gentle damping and support of the limiting wire prevents excessive deformation or uneven stress on the deformation ring, making the water flow pattern more regular. This solves the hidden problems of easy skewing and water flow dispersion when using clay alone. The flexible wrapping design of the isolation layer not only avoids friction damage between the hard nozzle and the skin, but also improves the grip stability when operating with wet hands, reducing rinsing deviation or accidental damage caused by instrument slippage. Reduce operational complexity and infection risk; there is no need to prepare multiple sizes of special nozzles, nor is it necessary to disassemble and replace nozzles during the nursing process. This reduces operational steps and the frequency of instrument disassembly and assembly, lowers the risk of cross-infection of instruments, and shortens the nursing time. It facilitates disinfection and replacement, ensuring sterility. The positioning ring and the connection port are threaded together, allowing for quick disassembly of the isolation layer, putty, and limiting wire. The isolation layer, putty, and limiting wire can be replaced at once, and the main body of the tube can be directly immersed for disinfection, achieving the purpose of facilitating disinfection and assembly.

[0015] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0016] Please see Figures 1 to 6 The present invention provides the following technical solutions: A wound cleaning device for neurosurgical care includes a tube body 1, on which a spraying mechanism 2 is provided; The bottom end of the tube body 1 is provided with an adjustment mechanism 3. The adjustment mechanism 3 includes a support ring 31, a deformation ring 32, a connection port 33 and an isolation layer 34. Multiple connection grooves 35 are provided on the deformation ring 32. Limiting wires 36 are movably engaged inside the connection grooves 35. A positioning ring 37 is threaded onto the connection port 33, and a positioning pad 38 is fixedly connected to the top of the positioning ring 37. The isolation layer 34 has a placement groove 39 inside, and clay 40 is movably placed inside the placement groove 39. The outer wall of the isolation layer 34 is fixedly connected with an anti-slip texture 41.
[0017] The spraying mechanism 2 includes a moving rod 21, an inlet / outlet 22, and two lever plates 23. A piston 24 is fixedly connected to the bottom end of the moving rod 21, and a pressing plate 25 is fixedly connected to the top end of the moving rod 21. The moving rod 21 is slidably connected to the top wall of the pipe body 1, and the bottom end of the moving rod 21 slides through the top wall of the pipe body 1 and is fixedly connected to the piston 24. The moving rod 21 can drive the piston 24 to move inside the pipe body 1 with the support of the pipe body 1. The inlet / outlet 22 is located at the center of the bottom end of the pipe body 1. At this location, the inlet / outlet 22 is in a continuous state with the pipe body 1, and the medicine in the pipe body 1 can be sprayed out through the inlet / outlet 22. The lever plate 23 is symmetrically fixedly connected to the pipe body 1 near the top position. The operator can press the pressing plate 25 by holding the lever plate 23 with their fingers. A sealing gasket is provided at the connection between the pipe body 1 and the moving rod 21 to prevent leakage at the connection between the pipe body 1 and the moving rod 21. The support ring 31 is fixedly connected to the bottom end of the pipe body 1 at the position corresponding to the inlet / outlet 22. At the location, the diameter of the support ring 31 is larger than the diameter of the inlet / outlet 22. The deformable ring 32 is fixedly connected to the bottom end of the pipe body 1 at the position corresponding to the outer ring of the support ring 31. The deformable ring 32 is made of medical liquid silicone. The inner ring of the deformable ring 32 abuts against the outer ring of the support ring 31. The support ring 31 can provide support for the connection between the deformable ring 32 and the pipe body 1 to prevent deformation. The connection port 33 is fixedly connected to the bottom end of the pipe body 1 at the position corresponding to the outer ring of the deformable ring 32. The connection port 33 is annular. The top of the isolation layer 34 is turned outward and abuts against the top of the positioning pad 38. The positioning pad 38 can fix the isolation layer 34 to the bottom end of the pipe body 1. The isolation layer 34 is located between the deformable ring 32 and the positioning ring 37. The limiting wire 36 is made of medical ultra-fine elastic stainless steel wire. Multiple leverage rods arranged in an array are fixedly connected to the outer wall of the positioning ring 37. The positioning pad 38 is made of rubber. The isolation layer 34 is flexible and can change shape with the clay 40.
[0018] In use, the isolation layer 34 and the deformable ring 32 can be inserted into the cleaning agent to be used. By pressing the plate 25 and moving the rod 21 upward, the rod 21 will drive the piston 24 to move upward inside the tube 1. At this time, the agent can be drawn into the tube 1 through the inlet and outlet 22. After the tube 1 has contained the agent, the shape of the isolation layer 34 and the deformable ring 32 can be changed according to the shape of the wound on the patient's head, so that the tube 1 can release agents with different flow patterns. The deformable ring 32 needs to be changed to a flat shape. When pressing the surface of the isolation layer 34, the anti-slip texture 41 on the surface of the isolation layer 34 makes it easier for staff to operate the isolation layer 34 and prevents it from slipping due to wet hands. Squeezing the isolation layer 34 flattens it, and the pressure is transmitted to the clay 40, causing the clay 40 to gradually change from a cylindrical shape to a flat shape. Simultaneously, the pressure from both the isolation layer 34 and the clay 40 is transmitted to the deformation ring 32, which also changes shape under pressure. As the shape changes, the corresponding limiting wire 36 under pressure also changes shape. The deformed limiting wire 36 provides support for the deformation of the deformable ring 32, making its deformation more uniform. It has mild elasticity and a certain degree of damping. Together with the clay 40, it can provide support for the deformation of the deformable ring 32, preventing the deformable ring 32 from rebounding when subjected to water pressure. The support ring 31 at the bottom of the pipe body 1 provides support for the deformable ring 32 at the position corresponding to the pipe body 1, preventing accidental deformation. At this time, the deformable ring 32 and the partition After the separation layer 34 has deformed, the lever plate 23 can be fastened and the pressing plate 25 can be pressed. The pressing plate 25 moves down and drives the moving rod 21 and the piston 24 to move down together inside the tube 1, thereby discharging the medicine inside the tube 1 through the inlet and outlet 22. At this time, the medicine will flow out at the bottom of the deformation ring 32. The medicine flows in a flat shape, which achieves the purpose of changing the flow of the medicine, so that the cleaning device can better adapt to wounds of different shapes and at different times. The isolation layer 34 in the adjustment mechanism 3 can prevent the cleaning agent from contacting the clay 40. During disinfection, simply rotate the positioning ring 37 using the lever to separate the positioning ring 37, positioning pad 38, and connection port 33. At this time, the positioning pad 38 no longer fixes the outwardly turned part at the top of the isolation layer 34, and the isolation layer 34 is released from fixation. It can be directly removed from the bottom of the tube body 1. Then, discard the used isolation layer 34 and modeling clay 40. Then, actively press the deformation ring 32 without changing the shape of the limiting wire 36. The deformation of the deformation ring 32 makes it easier for the staff to remove the limiting wire 36 from the connection groove 35. Discard the used limiting wire 36. At this time, the cleaning device can be directly immersed in the disinfectant water for disinfection. After disinfection, actively flatten the deformable ring 32, then insert the new limiting screws 36 into the connecting grooves 35. Release the deformable ring 32, which will automatically reset. Then replace the new isolation layer 34 and modeling clay 40. Place the modeling clay 40 into the placement groove 39 on the isolation layer 34, and then fold the top of the isolation layer 34 outwards. Figure 4 The top of the isolation layer 34 is turned outward, and then it is fitted onto the outer layer of the deformation ring 32, so that the turned-out part of its top abuts against the bottom of the tube body 1. Then, the positioning ring 37 and the positioning pad 38 are connected to the connection port 33 again, so that the positioning pad 38 presses the turned-out part of the top of the isolation layer 34 again, thereby completing the fixation of the isolation layer 34. At this time, the complete cleaning device is assembled and can be stored in a sterile environment for the next use.
