Description
Technical Field
[0001] This utility model relates to the field of wound irrigation technology, and in particular to an auxiliary irrigation device for animal bite wounds. Background Technology
[0002] In daily life, in outdoor, wilderness, and home first aid scenarios, people are easily infected with various germs after being bitten by animals, such as rabies virus and tetanus bacteria. If they cannot go to the hospital in time, they need to thoroughly rinse the wound themselves. This is the key first step in preventing infection. However, because the wound is small and deep, it is not easy to treat. People often use wound irrigation equipment to treat the wound.
[0003] The wound irrigation equipment mainly consists of an irrigation nozzle, a reservoir, a manual pressure pump, a waste fluid collection bag, and a drainage tube. The pressure pump is manually pressed to generate pressure, which sprays the irrigation fluid in the reservoir through the irrigation nozzle at a certain pressure to rinse the wound. The waste fluid after rinsing flows into the waste fluid collection bag through the drainage tube. At the same time, the lighting device can illuminate the wound, and the debridement tools facilitate the initial treatment of the wound.
[0004] In the prior art, some wound irrigation devices have their irrigation nozzles integrated with the device during use. However, the shape and depth of the bite wounds vary, and it is inconvenient to use only one type of nozzle to irrigate various wounds. Therefore, an animal bite wound irrigation device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an auxiliary irrigation device for animal bite wounds, which aims to improve the problem that the shape and depth of the bite wounds vary in the existing technology, and it is inconvenient to use only one type of nozzle to irrigate various wounds.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An auxiliary irrigation device for animal bite wounds includes a tubing, a mounting base fixedly connected to the right side of the tubing, a sealing ring fixedly connected to the outside of the mounting base, a needle detachably connected to the outside of the mounting base, a locking component provided on the outside of the needle to ensure the sealing of the connection between the mounting base and the needle, a connecting sleeve detachably connected to the outside of the needle, and a fixing component provided at the top of the tubing for easy medication administration.
[0008] As a further description of the above technical solution:
[0009] The locking assembly includes a limiting plate one, the outside of which is detachably connected to the outside of the needle, and a limiting plate two, the outside of which is detachably connected to the outside of the needle. A locking collar is threadedly connected to the outside of the limiting plate one and the outside of the limiting plate two.
[0010] As a further description of the above technical solution:
[0011] The outer side of the sealing ring is in contact with the inner wall of the first limiting plate, and the outer side of the sealing ring is in contact with the inner wall of the second limiting plate.
[0012] As a further description of the above technical solution:
[0013] An extension tube is slidably connected to the inner wall of the connecting sleeve, and a rubber clamp is fixedly connected to one side of the extension tube;
[0014] As a further description of the above technical solution:
[0015] A push rod is slidably connected to the inner wall of the tube, a piston is fixedly connected to the outside of the push rod, and two auxiliary grips are fixedly connected to the outer left side of the tube.
[0016] As a further description of the above technical solution:
[0017] The fixing component includes a dosing tube, the bottom of which is detachably connected to the outside of the cylinder. Two locking blocks are fixedly connected to the bottom of the dosing tube, and locking grooves are provided on both the left and right sides of the top of the cylinder.
[0018] As a further description of the above technical solution:
[0019] The outer side of the rubber clamp is slidably connected to the inner wall of the connecting sleeve, and the inner wall of the piston is slidably connected to the inner wall of the cylinder.
[0020] As a further description of the above technical solution:
[0021] A sealing plug is fixedly connected to the top of the dosing tube, and the outside of the locking block engages with the inner wall of the locking groove.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the locking collar is first rotated. Because it is connected to the first and second limiting plates by threads, the locking collar can be easily removed from the outside of the two. Then, the first and second limiting plates are removed. After pushing the rubber clamp and extension tube out of the connecting sleeve, the needle is put into the connecting sleeve. Then, the first and second limiting plates are clamped on the sealing ring and the outside of the needle. Finally, the locking collar is tightened. The whole process is clear and the connection is stable. Users can quickly replace the flushing head according to the wound condition, which greatly improves the treatment efficiency and saves valuable time for the timely treatment of animal bites.
[0024] 2. In this invention, the locking block and the slot fit tightly, and the friction is sufficient to ensure the stability of the drug delivery tube during daily use, preventing it from shaking or falling off. The sealing plug at the top of the drug delivery tube is crucial, made of soft and elastic rubber. When medication is needed, medical personnel simply insert the syringe containing the medication into the sealing plug. The sealing plug tightly encloses the syringe to ensure a seal, preventing medication evaporation and external contamination. It also quickly returns to its original shape after the syringe is removed, maintaining a closed seal and ensuring the purity of the mixture inside the tube. This provides a reliable medication guarantee for subsequent wound irrigation. The entire medication delivery process is simple, efficient, and hygienic. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1 to 2 This utility model provides an embodiment of an auxiliary rinsing device for animal bite wounds, including a tube 1, which serves as the main supporting component of the entire device. A mounting base 2 is fixedly connected to the right side of the tube 1, and a sealing ring 3 is fixedly connected to the outside of the mounting base 2. The sealing ring 3 not only prevents the outflow of the medicine, but also prevents external bacteria, impurities and other contaminants from entering the tube 1 through the connection gap and contaminating the medicine, ensuring that the medicine used to rinse the wound remains clean and sterile each time, thus providing a safety guarantee for the treatment of animal bite wounds.
[0033] The mounting base 2 is detachably connected to a needle 4, which can be easily inserted into the deep crevices of the wound, ensuring that the rinsing solution can reach every corner of the wound and thoroughly clean deep infected areas. The mounting base 2 is a key transition component connecting the tube 1 and the needle 4. When the needle 4 is inserted into the mounting base 2, the sealing ring 3 will tightly hold the needle 4 under its own elasticity, filling the tiny gap between the two.
[0034] The needle 4 is provided with a locking component on its outside. The locking component can ensure the sealing of the connection between the mounting base 2 and the needle 4. The locking component includes a limiting plate 5. The limiting plate 5 is detachably connected to the outside of the needle 4. During the installation process, the limiting plate 5 is first put on the needle 4 so that its inner wall is in close contact with the outer wall of the sealing ring 3 to ensure the sealing effect. At the same time, it provides the initial positioning and limiting function for the entire connection structure.
[0035] The needle 4 is detachably connected to a limiting plate 2 6. The outer side of the sealing ring 3 contacts the inner wall of the limiting plate 1 5, and the outer side of the sealing ring 3 contacts the inner wall of the limiting plate 2 6. Together with the limiting plate 1 5, they clamp the sealing ring 3, further enhancing the sealing performance and limiting the needle 4 from both the top and bottom directions to prevent the needle 4 from shaking or shifting during the rinsing process. The outer side of the limiting plate 1 5 and the outer side of the limiting plate 2 6 are threadedly connected to a locking collar 7. After the limiting plate 1 5 and the limiting plate 2 6 are fitted onto the needle 4 and are in close contact with the sealing ring 3, the locking collar 7 is screwed onto the outer side of the two plates by rotating the threads, gradually tightening it so that the limiting plate 1 5 and the limiting plate 2 6 fit tightly together, applying a stable clamping force to the needle 4, ensuring the stability and sealing of the entire connection structure, and allowing the rinsing operation to be carried out safely and smoothly.
[0036] A connecting sleeve 8 is detachably connected to the outside of the needle 4. An extension tube 10 is slidably connected to the inner wall of the connecting sleeve 8. The connecting sleeve 8 is used to connect the extension tube 10 and the needle 4, enabling switching between different irrigation methods. A rubber clamp 9 is fixedly connected to one side of the extension tube 10. When the extension tube 10 is inserted into the connecting sleeve 8, the rubber clamp 9 will deform to a certain extent under its own elasticity, smoothly passing through the port of the connecting sleeve 8, and then return to its original shape, tightly fitting against the inner wall of the connecting sleeve 8, providing reliable fixed support for the extension tube 10 and ensuring the stability of the shallow wound irrigation process.
[0037] The rubber clamp 9 is externally slidably connected to the inner wall of the connecting sleeve 8. One end of the extension tube 10 is fixedly connected to the rubber clamp 9. The rubber clamp 9 is circular and its outer diameter is slightly larger than the inner diameter of the connecting sleeve 8. When the extension tube 10 is inserted into the connecting sleeve 8, the rubber clamp 9 will lock into the inner wall of the connecting sleeve 8, thus fixing the extension tube 10 and preventing it from accidentally coming out during rinsing. At the same time, the friction between the rubber clamp 9 and the inner wall of the connecting sleeve 8 will not be too great, so that the extension tube 10 can be easily pulled out when the rinsing method needs to be changed.
[0038] Reference Figures 3 to 4 A push rod 11 is slidably connected to the inner wall of the tubing 1, and a piston 12 is fixedly connected to the outside of the push rod 11. The push rod 11 is mainly used to push the piston 12 inside the tubing 1 to discharge the medicine. The inner wall of the piston 12 is slidably connected to the inner wall of the tubing 1. When the piston 12 is installed inside the tubing 1, the sealing ring can tightly fit the inner wall of the tubing 1. As the push rod 11 pushes, the piston 12 slides smoothly inside the tubing 1, gradually squeezing out the medicine inside the tubing 1, while preventing the medicine from flowing back from the gap between the piston 12 and the inner wall of the tubing 1, ensuring the unidirectionality and high efficiency of the rinsing process.
[0039] Two auxiliary grips 13 are fixedly connected to the outer left side of the tube 1. The shape of the auxiliary grips 13 is designed to fit the gripping habits of the human hand. They are generally slightly concave, which makes it easy for the fingers to bend naturally and place them. This provides medical staff with a stable and comfortable gripping experience when operating the rinsing equipment, which helps to accurately control the rinsing force and reduce hand fatigue. A fixing component is set at the top of the tube 1. The fixing component facilitates the addition of medicine. The fixing component includes a medicine addition tube 14. The medicine addition tube 14 serves as a channel for adding medicine into the tube 1. It is made of transparent medical plastic and has scale lines marked on the outside to facilitate the observation of the medicine injection.
[0040] The bottom of the dosing tube 14 is detachably connected to the outside of the tube 1. Two locking blocks 15 are fixedly connected to the bottom of the dosing tube 14. The top left and right sides of the tube 1 have locking grooves 16. The outside of the locking block 15 engages with the inner wall of the locking groove 16. The locking block 15 fits tightly with the inner wall of the locking groove 16. When inserted into the locking groove 16, it can provide sufficient friction to ensure that the dosing tube 14 will not easily shake or fall off during normal use, thus ensuring the stability of the dosing operation. The top of the dosing tube 14 is fixedly connected to a sealing plug 17. The sealing plug 17 is made of rubber, which is soft and elastic. When it is necessary to inject medicine into the dosing tube 14, simply insert the syringe containing the medicine into the sealing plug 17 to complete the dosing operation smoothly. At the same time, the sealing plug 17 can effectively prevent the medicine from evaporating and external contamination from entering the dosing tube 14.
[0041] Working principle: First, place the tubing 1 in a suitable position, then insert the syringe containing the medicine into the sealed plug 17, inject the medicine into the drug delivery tube 14, and then the medicine mixes with the mixture inside the tubing 1. Then push the push rod 11, and the piston 12 slides on the inner wall of the tubing 1, pushing the medicine out. If the wound is shallow, use the extension tube 10 for flushing. At this time, the flushing force is relatively light and will not cause the patient much pain.
[0042] If the wound is deep, rotate the locking collar 7 to remove it from the outside of the limiting plate 5 and the limiting plate 6. Then remove the limiting plate 5 and the limiting plate 6. Push the rubber clamp 9 and the extension tube 10 out of the connecting sleeve 8 in the opposite direction. Then insert the needle 4 into the connecting sleeve 8. Secure the limiting plate 5 and the limiting plate 6 to the outside of the sealing ring 3 and the needle 4. Finally, tighten the locking collar 7 to the outside of the limiting plate 5 and the limiting plate 6. This allows the needle 4 to be used to rinse the wound. The rinsing force is strong at this time, which can thoroughly clean deep wounds. After rinsing, the needle 4 and the extension tube 10 can be removed and cleaned in time to maintain hygiene. Then, push the drug delivery tube 14 upward to separate the clamp 15 from the groove 16, thereby cleaning the drug delivery tube 14.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
