Abstract
Description
Technical Field
[0001] This utility model relates to the field of wound cleaning and nursing technology, specifically to a wound cleaning and disinfection nursing device. Background Technology
[0002] Traditional wound care requires the use of tools such as tweezers, cotton balls, and gauze. The cotton ball is held with tweezers and then dipped in saline solution, iodine solution, or other disinfectant for cleaning and disinfection. The tools required are scattered and inconvenient to carry.
[0003] Application number 202321089376.5 discloses a wound cleaning, disinfection, and care device, which differs from traditional wound cleaning methods:
[0004] By moving the reservoir tube, the reservoir tube moves the sponge sleeve into contact with the wound surface. By pushing the reservoir tube, the reservoir tube moves the sponge sleeve to roll and disinfect the wound surface.
[0005] By setting up a pull plate, spring, and locking rod, the pull plate is pulled, and under the elastic force of the spring, the pull plate drives the second movable plate to move through the pull rod. The second movable plate drives the locking rod to disengage from the movable groove. The movable roller facilitates the disassembly of the roller and the replacement of the sponge sleeve.
[0006] When the above-mentioned sponge sleeve is rolled on the wound surface, if the force is too small, the sponge sleeve will not be able to fit the wound surface. If the force is too large, it will increase the patient's pain during debridement. In fact, this roller contact method is far less gentle than the static contact between the cotton ball and the wound surface. In addition, the sponge sleeve cannot be completely cleaned after use and can only be replaced with a new one. Due to the large amount of material used for the sponge sleeve, the consumable cost of this solution is relatively large.
[0007] Furthermore, there is room for improvement in simplifying the process of replacing consumables in this solution. Utility Model Content
[0008] The purpose of this invention is to provide a wound cleaning, disinfection and nursing device to solve the above problems, as detailed below.
[0009] To achieve the above objectives, the present invention provides the following technical solution:
[0010] This utility model provides a wound cleaning, disinfection and nursing device, including a sleeve, which can be vertically filled with a number of sterile cotton balls. The lower end of the sleeve is fixedly connected to a clamping component for holding the sterile cotton balls and a disinfectant injection mechanism for injecting disinfectant into the sterile cotton balls.
[0011] A piston is slidably connected inside the sleeve for pushing a sterile cotton ball from inside the sleeve into the clamping assembly. A push rod is fixedly connected to the piston.
[0012] Using the above-mentioned wound cleaning, disinfection and nursing device, the sleeve is filled with sterile cotton balls. The inner diameter of the sleeve is adapted to the size of the regular sterile cotton balls, and the sterile cotton balls are arranged vertically inside the sleeve.
[0013] The piston is pushed by a push rod, which moves the sterile cotton ball from the sleeve to the clamping assembly. The clamping assembly holds the sterile cotton ball, and then the disinfectant injection mechanism injects disinfectant into the sterile cotton ball, saturating it. The sterile cotton ball is then used to disinfect the patient's wound. The sterile cotton ball can absorb the blood clots and damaged tissue adhering to the wound surface. After a large amount of blood clots have been absorbed by the surface of a sterile cotton ball, the clamping assembly is released from the current sterile cotton ball, and the used sterile cotton ball will fall off the clamping assembly. The above steps are then repeated, and a new sterile cotton ball is pushed to the clamping assembly and saturated with disinfectant to continue the wound cleaning work.
[0014] Preferably, the push rod is longer than the sleeve, and the upper end of the push rod passes through the upper end of the sleeve, and a handle is fixedly connected to the surface of the sleeve.
[0015] Preferably, the disinfectant dispensing mechanism includes a syringe mounted on the surface of a sleeve and an annular tube fixedly connected to the lower end of the sleeve. A connecting hose is connected to the annular tube, and the other end of the connecting hose is inserted into the output end of the syringe. Several spray holes are provided on the inner side of the annular tube.
[0016] Preferably, a fixing sleeve is fixedly connected to the surface of the sleeve, and a syringe is inserted into the fixing sleeve, with the upper side of the fixing sleeve contacting the bottom of the baffle on the surface of the syringe.
[0017] Preferably, the clamping assembly includes a plurality of ear plates fixedly connected to the surface of the sleeve in a circular array. A rotating shaft is rotatably connected to the ear plates, and a clamping plate is fixedly connected to the rotating shaft. A torsion spring is sleeved on the rotating shaft for rotating the rotating shaft to flip the clamping plate upward. A slip ring is slidably connected to the surface of the sleeve, and a fixing rod is fixedly connected to the end of the rotating shaft, with the bottom of the slip ring corresponding to the fixing rod.
[0018] Preferably, a control lever is fixedly connected to the slip ring.
[0019] Preferably, the two ends of the torsion spring are fixedly connected to the ear plate and the rotating shaft, respectively.
[0020] Preferably, the clamping plate has several protrusions on the side corresponding to the sleeve.
[0021] The beneficial effects are:
[0022] 1. The sterile cotton ball is moved from the sleeve to the clamping component by the piston. The clamping component holds the sterile cotton ball and the disinfectant is injected into the sterile cotton ball by the disinfectant injection mechanism, so that the sterile cotton ball is saturated with disinfectant. The sterile cotton ball is then used to disinfect the patient's wound. Compared with the traditional method, this device integrates the steps of changing cotton balls, dipping in disinfectant, and clamping cotton balls, making the device easy to carry and significantly reducing the number of items that need to be carried when going out for rescue.
[0023] 2. While adopting an integrated design, the device retains the contact method between sterile cotton balls and the wound, which is still static contact, thereby reducing patient pain. Furthermore, the cost of sterile cotton balls as consumables is lower than that of sponge sleeves in existing technologies.
[0024] 3. Through the cooperation of the sleeve, piston and clamping components, new sterile cotton balls can be quickly replaced, thereby significantly improving the efficiency of wound cleaning. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0034] See Figures 1-5 As shown, this utility model provides a wound cleaning, disinfection and nursing device, including a sleeve 1, which can vertically fill a number of sterile cotton balls. The lower end of the sleeve 1 is fixedly connected to a clamping component 5 for clamping the sterile cotton balls and a disinfectant injection mechanism 6 for injecting disinfectant into the sterile cotton balls.
[0035] A piston 2 is slidably connected inside the sleeve 1, which is used to push the sterile cotton ball from inside the sleeve 1 into the clamping assembly 5. A push rod 3 is fixedly connected to the piston 2.
[0036] As an optional implementation, the push rod 3 is longer than the sleeve 1, and the upper end of the push rod 3 passes through the upper end of the sleeve 1, with a handle 4 fixedly connected to the surface of the sleeve 1.
[0037] The disinfectant dispensing mechanism 6 includes a syringe 8 mounted on the surface of the sleeve 1 and an annular tube 10 fixedly connected to the lower end of the sleeve 1. A connecting hose 9 is connected to the annular tube 10, and the other end of the connecting hose 9 is inserted into the output end of the syringe 8. Several spray holes 11 are provided on the inner side of the annular tube 10.
[0038] After the sterile cotton ball is held by the clamping component 5, the sterile cotton ball corresponds to the spray hole 11. By pressing the syringe 8, the disinfectant flows through the ring tube 10 into the sterile cotton ball. While holding the handle 4, the medical staff can use their thumb to press the piston of the syringe.
[0039] A fixing sleeve 7 is fixedly connected to the surface of the sleeve 1, and a syringe 8 is inserted into the fixing sleeve 7. The upper side of the fixing sleeve 7 contacts the bottom of the baffle on the surface of the syringe 8. The fixing sleeve 7 is set to facilitate the installation of the syringe 8. After the disinfectant in the syringe 8 is used up, the connecting hose 9 is disconnected from the syringe 8, and then the syringe 8 is taken out from the fixing sleeve 7 to facilitate the syringe 8 to draw up and replenish the disinfectant.
[0040] The clamping assembly 5 includes several ear plates 12 fixedly connected to the surface of the sleeve 1 in a circular array. A rotating shaft 14 is rotatably connected to the ear plates 12. A clamping plate 16 is fixedly connected to the rotating shaft 14. A torsion spring 13 is sleeved on the rotating shaft 14 for rotating the rotating shaft 14 to flip the clamping plate 16 upward. A slip ring 18 is slidably connected to the surface of the sleeve 1. A fixing rod 15 is fixedly connected to the end of the rotating shaft 14, and the bottom of the slip ring 18 corresponds to the fixing rod 15.
[0041] Push the slip ring 18 downwards, so that the slip ring 18 pushes the fixing rod 15 downwards. The fixing rod 15 cooperates with the rotating shaft 14 to swing the clamping plate 16, so that multiple clamping plates 16 come closer to each other to hold the sterile cotton ball.
[0042] When the slip ring 18 is released, the clamp 16 will automatically flip upward under the action of the torsion spring 13. At that time, the multiple clamps 16 will move away from each other, and the sterile cotton ball will fall from between the multiple clamps 16.
[0043] A control lever 19 is fixedly connected to the slip ring 18. The control lever 19 allows medical staff to hold the handle 4 and press the control lever 19 with their thumb, causing the slip ring 18 to move downward and push the fixed rod 15.
[0044] The two ends of the torsion spring 13 are fixedly connected to the ear plate 12 and the rotating shaft 14, respectively.
[0045] The clamp 16 is provided with several protrusions 17 on the side corresponding to the sleeve 1. The protrusions 17 can improve the stability of the clamp 16 in holding the sterile cotton ball.
[0046] Using the above structure, the sleeve 1 is filled with sterile cotton balls. The inner diameter of the sleeve 1 is adapted to the size of conventional sterile cotton balls, and the sterile cotton balls are arranged vertically inside the sleeve 1.
[0047] The piston 2 is pushed by the push rod 3, which moves the sterile cotton ball from the sleeve 1 to the clamping component 5. The clamping component 5 clamps the sterile cotton ball, and then the disinfectant injection mechanism 6 injects disinfectant into the sterile cotton ball, saturating it with disinfectant. The sterile cotton ball is then used to disinfect the patient's wound. The sterile cotton ball can absorb the blood clots and damaged tissue adhering to the wound surface. After a large amount of blood clots have been absorbed by the surface of a sterile cotton ball, the clamping component 5 is released from the current sterile cotton ball, and the used sterile cotton ball will fall off the clamping component 5. The above steps are then repeated, and a new sterile cotton ball is pushed to the clamping component 5 and saturated with disinfectant to continue the wound cleaning work.
[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
