Abstract
Description
Technical Field
[0001] This utility model relates to the field of clinical technology in otolaryngology; specifically, it relates to a nasal cavity expansion and contraction adjustment irrigation device. Background Technology
[0002] A nasal irrigation device is a medical device used to clean and rinse the nasal cavity. It is commonly used to relieve nasal problems such as rhinitis, allergic rhinitis, and sinusitis. By using saline or physiological saline, nasal irrigation can help remove mucus, allergens, and pathogens from the nasal cavity, relieving symptoms such as nasal congestion and runny nose. The user pours saline into one nostril, and the liquid flows out from the other nostril, which helps to clean the nasal cavity.
[0003] Currently, most existing nasal irrigation devices do not have a telescopic structure. In actual operation, the irrigation tube may not be long enough, making it difficult to fully irrigate the nasal cavity. This reduces the reliability of the device to some extent. In addition, most existing nasal irrigation devices do not have a flexible tube tip. When the device is inserted into the nasal cavity, the tip of the irrigation tube may damage the inner wall of the nasal cavity, which is not conducive to safe irrigation and affects the safety of the device to some extent. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a nasal cavity telescopic adjustment irrigation device to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: a nasal cavity telescopic adjustable irrigation device, comprising:
[0006] A liquid storage mechanism, wherein the liquid storage mechanism includes a liquid storage bottle;
[0007] A flushing conduit, the flushing conduit including a first conduit, wherein the outer surface of one end of the first conduit is connected to the interior of the outer surface of the liquid storage mechanism;
[0008] The protective mechanism includes a fixing ring, and the inner surface of the fixing ring is fixedly connected to the outer surface of the flushing conduit.
[0009] Preferably, the liquid storage mechanism further includes a bottle cap, and the outer surface of one side of the bottle cap is threadedly connected to the outer surface of the lower end of the liquid storage bottle, and the outer surface of one end of the first conduit is connected to the interior of the lower end of the outer surface of the bottle cap, and the interior of the liquid storage bottle is used to store rinsing liquid.
[0010] Preferably, the flushing conduit further includes a locking groove, which is formed inside the inner surface of one end of the first conduit, and multiple sets of locking grooves are provided. A second conduit is inserted inside the other end of the first conduit, and the inner surface of the fixing ring is fixedly connected to the outer surface of one end of the second conduit. The second conduit can extend and retract inside the first conduit.
[0011] Preferably, insertion holes are provided on both sides of the outer surface of the other end of the second conduit, and a return spring is inserted into the insertion hole. A locking block is fixedly connected to the outer surface of one end of the return spring. The outer surface of one end of the locking block is locked into the inside of the locking groove. The locking block can be locked into any set of locking grooves.
[0012] Preferably, the protective mechanism further includes a buffer spring, and the outer surface of one end of the buffer spring is fixedly connected to the outer surface of one side of the fixing ring, and the fixing ring can restrict the position of the buffer spring.
[0013] Preferably, a buffer head is fixedly connected to the outer surface of the other end of the buffer spring, and one end of the buffer head is sleeved on the outer surface of one end of the second conduit, and the buffer head can extend and retract on the outer surface of the second conduit.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] 1. This utility model, by setting up a flushing conduit, allows the locking block to first contract and squeeze the return spring during actual operation by pulling the second conduit. Then, relying on the elasticity of the return spring itself, the locking block is reset and locked into the locking groove in other positions until the length of the flushing conduit is appropriate. This reduces the possibility of insufficient length of the flushing conduit, making it easier to fully flush the nasal cavity and improving the reliability of the equipment to a certain extent.
[0016] 2. By setting up a protective mechanism, when the device is inserted into the nasal cavity, the front end of the buffer head enters the nasal cavity and retracts backward when it touches the inner wall, squeezing the buffer spring. This reduces the possibility of the front end of the irrigation tube damaging the inner wall of the nasal cavity, which is conducive to safe irrigation and improves the safety of the device to a certain extent.

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The nasal cavity telescopic adjustment irrigation device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] Example 1
[0026] like Figures 1 to 5 As shown, this utility model proposes a nasal cavity telescopic adjustment irrigation device, including a liquid storage mechanism 1. The liquid storage mechanism 1 includes a liquid storage bottle 11 and a bottle cap 12. The outer surface of one side of the bottle cap 12 is threaded to the outer surface of the lower end of the liquid storage bottle 11, and the outer surface of one end of the first conduit 21 is connected to the interior of the lower end of the outer surface of the bottle cap 12. The liquid storage bottle 11 is used to store irrigation liquid. After the device is inserted into the predetermined position, squeezing the liquid storage bottle 11 can push the irrigation liquid into the nasal cavity.
[0027] The flushing conduit 2 includes a first conduit 21, and the outer surface of one end of the first conduit 21 is connected to the interior of the outer surface of the liquid storage mechanism 1. The flushing conduit 2 also includes a locking groove 22, which is formed inside the inner surface of one end of the first conduit 21. Multiple sets of locking grooves 22 are provided. A second conduit 23 is inserted into the interior of the other end of the first conduit 21. The inner surface of the fixing ring 31 is fixedly connected to the outer surface of one end of the second conduit 23. The second conduit 23 can extend and retract inside the first conduit 21 and can be fixed at any length by multiple sets of locking grooves 22.
[0028] The second catheter 23 has insertion holes 24 on both sides of its outer surface at the other end. A return spring 25 is inserted into the insertion hole 24. A locking block 26 is fixedly connected to the outer surface of one end of the return spring 25. The outer surface of one end of the locking block 26 engages with the inside of the locking groove 22. By pulling the second catheter 23, the locking block 26 can first retract into the insertion hole 24 and squeeze the return spring 25. Then, when the locking block 26 moves to the position of the locking groove 22, the elasticity of the return spring 25 will reset and engage the locking block 26 into the locking groove 22 at other positions, thus fixing the position of the second catheter 23 until the length of the irrigation catheter 2 is appropriate and it can be inserted into the nasal cavity.
[0029] Example 2
[0030] like Figure 1 and Figure 6 As shown, this embodiment also proposes:
[0031] The protective mechanism 3 includes a fixing ring 31, and the inner surface of the fixing ring 31 is fixedly connected to the outer surface of the flushing tube 2. The protective mechanism 3 also includes a buffer spring 32, and the outer surface of one end of the buffer spring 32 is fixedly connected to the outer surface of one side of the fixing ring 31. When the buffer head 33 is blocked, the buffer spring 32 can be squeezed backward. The buffer spring 32 can buffer the buffer head 33 and prevent the front end from injuring the inner wall of the nasal cavity.
[0032] A buffer head 33 is fixedly connected to the outer surface of the other end of the buffer spring 32, and one end of the buffer head 33 is sleeved on the outer surface of one end of the second catheter 23. The buffer head 33 is made of silicone. Silicone is a widely used synthetic polymer known for its excellent physical and chemical properties. Its main components are alternating structures of silicon and oxygen elements, and it is usually combined with other elements such as carbon and hydrogen to form different types of silicone. Silicone is a biocompatible material and is often used in medical devices and implants. It is not likely to cause allergies or adverse reactions. Silicone has good flexibility and elasticity, making it suitable for applications that require flexibility, such as catheters for nasal irrigators. The surface of silicone is smooth, does not easily accumulate bacteria, and is easy to clean and disinfect, making it suitable for applications with high hygiene requirements. The buffer head 33 can extend and retract on the outer surface of the second catheter 23, thereby protecting the patient's nasal cavity from damage.
[0033] Working principle: First, fill the inside of the storage bottle 11 with rinsing fluid. Then, pull the second tube 23 to move inside the first tube 21, causing the locking block 26 to contract and squeeze the return spring 25. Then, relying on the elasticity of the return spring 25, the locking block 26 is reset and locked into the locking groove 22 in other positions until the length of the rinsing tube 2 is appropriate. Then, it can be inserted into the nasal cavity from the front end of the protective mechanism 3. The front end of the buffer head 33 enters the nasal cavity and retracts when it touches the inner wall, squeezing the buffer spring 32 to protect the inner wall of the nasal cavity. When it is inserted to the appropriate position, squeeze the storage bottle 11 to rinse. The above is the complete working principle of this utility model.
[0034] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
