An anesthetic spray device

Abstract

This utility model relates to the field of medical equipment technology; and discloses an anesthetic sprayer, including a main structure comprising a reservoir, a limiting plate, a sealing cap, a sealing gasket, and a fixing plate; and a fixing structure comprising a connecting pipe, a connecting seat, a clamping plate, a fixing nut, and a spray pipe, wherein the connecting pipe is connected to the interior of the sealing cap. This utility model achieves this by having the lower surface of the sealing cap adhere to the upper surface of the reservoir, thereby causing the lower surface of the upper end of the sealing gasket to adhere to the upper surface of the limiting plate, and simultaneously inserting the fixing plate into the interior of the limiting plate. Rotating the sealing cap causes the sealing gasket and the fixing plate to rotate synchronously, causing the upper surface of the fixing plate to adhere to the lower surface of the limiting plate, thus fixing the position of the sealing cap. Rotating the sealing cap causes the upper surface of the fixing plate to disengage from the lower surface of the limiting plate, allowing the sealing cap to be lifted upwards. This design allows medical personnel to clean the interior of the reservoir.

Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology; more specifically, it relates to an anesthetic spray device. Background Technology

[0002] An anesthetic spray is a medical device used for local anesthesia. It sprays anesthetic drugs evenly onto the target area, such as the skin or mucous membranes, to achieve a rapid anesthetic effect. Sprayers are commonly used for anesthesia before minor surgeries, dental treatments, or injections. They are simple to operate and can provide effective anesthesia in a short time.

[0003] Currently, existing anesthetic spray devices suffer from several problems during use. Firstly, the reservoir in some devices is typically a fixed unit. Over time, impurities may accumulate inside the reservoir, potentially affecting the effectiveness of subsequent medications or causing uneven drug concentrations during repeated use. Secondly, some existing devices involve directly inserting the nozzle into the device, which may come into contact with the patient's oral cavity, causing it to wobble. The lack of a secure structure for the nozzle can lead to it falling out, thus disrupting the anesthesia process. Therefore, there is an urgent need for an anesthetic spray device to address these issues. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anesthetic sprayer to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an anesthetic sprayer, comprising: The main structure includes a liquid storage tank, a limiting plate, a sealing cover, a sealing gasket, and a fixing plate; The fixing structure includes a connecting pipe, a connecting seat, a clamping plate, a fixing nut, and a spray pipe, and the connecting pipe is connected to the interior of the sealing cover.

[0006] Preferably, the main structure also includes scale lines, which are set on the outer surface of the liquid storage tank, and a limiting plate is fixedly connected to the upper end of the inner surface of the liquid storage tank. The scale lines allow medical staff to observe the anesthetic fluid inside the liquid storage tank more intuitively.

[0007] Preferably, a sealing cap is attached to the upper surface of the liquid storage tank, and a sealing gasket is fixedly connected to the lower surface of the sealing cap. A fixing plate is fixedly connected to the lower outer surface of the sealing gasket. The sealing gasket is made of rubber, thereby ensuring a tight seal between the gasket and the liquid storage tank.

[0008] Preferably, the size of the fixing plate is adapted to the size of the limiting plate, the lower surface of the upper end of the sealing gasket can be attached to the upper surface of the limiting plate, and a sealing plug is inserted inside the upper surface of the sealing cover. When the equipment is in use, the sealing plug can protect the inside of the liquid storage tank, thereby preventing dust from entering the inside of the liquid storage tank.

[0009] Preferably, the fixing structure further includes anti-slip texture, and the anti-slip texture is fixedly connected to the outer surface of one end of the connecting pipe, and a connecting seat is also fixedly connected to the outer surface of one end of the connecting pipe. The anti-slip texture is made of rubber, which can improve the sealing and friction with the inside of one end of the spray pipe.

[0010] Preferably, a clamping plate is fixedly connected to one end of the connecting seat, and a fixing nut is threadedly connected to the inside of the connecting seat. A spray pipe is fitted on the outer surface of the anti-slip texture. A locking groove is opened inside one end of the fixing nut, and the size of the locking groove is adapted to the size of the outer surface of one end of the clamping plate. When the fixing nut rotates inside the connecting seat, the locking groove can be used to push one end of the clamping plate inward to tighten it.

[0011] The technical effects and advantages of this utility model are as follows: This utility model attaches the lower surface of the sealing cap to the upper surface of the liquid storage tank, thereby making the lower surface of the upper end of the sealing gasket attach to the upper surface of the limiting plate. At the same time, the fixing plate is inserted into the interior of the limiting plate. Then, rotating the sealing cap causes the sealing gasket and the fixing plate to rotate synchronously, so that the upper surface of the fixing plate attaches to the lower surface of the limiting plate, thereby fixing the position of the sealing cap. Rotating the sealing cap causes the upper surface of the fixing plate to detach from the lower surface of the limiting plate, so that the sealing cap can be lifted upward. This design allows medical staff to clean the inside of the liquid storage tank, thereby avoiding impurities inside the liquid storage tank from affecting the anesthesia effect. This invention connects the spray tube to the connecting tube by fitting one end of the spray tube onto the anti-slip textured outer surface. Then, by rotating the fixing nut, it moves inside the connecting seat, causing the locking groove to abut against one end of the clamping plate, which tightens inward and clamps the outer surface of one end of the spray tube. This design allows the device to fix the spray tube, preventing it from shaking or falling off and improving the stability of the device during anesthesia. Attached Figure Description

[0020] 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 anesthetic sprayer 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.

[0021] Example 1 like Figures 1 to 4As shown, this utility model provides an anesthetic spray device, including: a main structure 1, which includes a reservoir 11, a limiting plate 13, a sealing cover 14, a sealing gasket 15, and a fixing plate 16. The main structure 1 also includes a scale line 12, which is disposed on the outer surface of the reservoir 11. The limiting plate 13 is fixedly connected to the upper end of the inner surface of the reservoir 11. The sealing cover 14 is attached to the upper surface of the reservoir 11, and the sealing gasket 15 is fixedly connected to the lower surface of the sealing cover 14. The fixing plate 16 is fixedly connected to the outer surface of the lower end of the sealing gasket 15. The size of the fixing plate 16 is adapted to the size of the limiting plate 13. The lower surface of the upper end of the sealing gasket 15 can be attached to the upper surface of the limiting plate 13. A sealing gasket is inserted into the interior of the upper surface of the sealing cover 14. The sealing plug 17 and the inside of the reservoir 11 are used to store anesthetic drugs. When using the device, the sealing plug 17 can be removed from the inside of the sealing cover 14, and then the anesthetic solution can be injected into the inside of the reservoir 11. Then, the sealing plug 17 can be inserted into the inside of the sealing cover 14 to seal the inside of the reservoir 11, preventing dust and other impurities in the air from entering the inside of the reservoir 11, thus keeping the anesthetic solution inside the reservoir 11 uncontaminated. The scale line 12 can help medical staff quickly identify the amount of anesthetic solution remaining in the reservoir 11, enabling medical staff to more accurately control the dosage of each spray during use, ensuring that the required effect is achieved, and avoiding medical staff from overusing anesthetic drugs, thereby reducing the risk of adverse reactions and medical accidents to patients. The sealing gasket 15 is made of rubber. The elasticity and compressibility of rubber allow it to fit well against the upper surface of the liquid storage tank 11, thereby forming a good seal at the connection and preventing gas or liquid leakage. The fixing plate 16 can be inserted into the interior of the limiting plate 13. When the sealing cover 14 is rotated, the sealing gasket 15 and the fixing plate 16 can rotate synchronously. The upper surface of the fixing plate 16 can fit against the lower surface of the limiting plate 13, thereby preventing the sealing cover 14 from detaching from the upper surface of the liquid storage tank 11. Rotating the fixing plate 16 detaches it from the lower surface of the limiting plate 13. At this time, the sealing cover 14 can be removed to clean the interior of the liquid storage tank 11.

[0022] Example 2 like Figures 5 to 7As shown, this embodiment also proposes a fixing structure 2, which includes a connecting pipe 21, a connecting seat 23, a clamping plate 24, a fixing nut 25, and a spray pipe 26. The connecting pipe 21 is connected to the interior of the sealing cap 14. The fixing structure 2 also includes anti-slip texture 22, which is fixedly connected to the outer surface of one end of the connecting pipe 21. The connecting seat 23 is also fixedly connected to the outer surface of one end of the connecting pipe 21. The clamping plate 24 is fixedly connected to one end of the connecting seat 23, and the fixing nut 25 is threadedly connected to the interior of the connecting seat 23. The spray pipe 26 is sleeved on the outer surface of the anti-slip texture 22. The fixing nut 25 is fixedly connected to the outer surface of the anti-slip texture 22. A locking groove is provided inside one end of the clamping plate 24, and the size of the locking groove is adapted to the size of the outer surface of one end of the clamping plate 24. The anti-slip texture 22 is made of rubber, which can increase the friction with the inside of one end of the spray pipe 26, thereby improving the stability of the spray pipe 26 during use. The fixing nut 25 can rotate inside the connecting seat 23, and can move inside the connecting seat 23 when rotating. When moving, the locking groove can push one end of the clamping plate 24 inward to tighten, thereby clamping the outer surface of one end of the spray pipe 26, thereby fixing the position of the spray pipe 26 and preventing the spray pipe 26 from falling off the outer surface of the anti-slip texture 22.

[0023] Working principle: When using the equipment, first pull out the sealing plug 17 and add the anesthetic liquid into the inside of the storage tank 11. Then, insert the sealing plug 17 into the inside of the sealing cover 14 to seal the sealing cover 14. Then, put one end of the spray pipe 26 onto the outer surface of the anti-slip texture 22 to connect the spray pipe 26 with the connecting pipe 21. Then, rotate the fixing nut 25 to make the locking groove abut against one end of the clamping plate 24 and tighten inward, thereby fixing the position of the spray pipe 26. Then, provide power to the storage tank 11 through an external power source. When the storage tank 11 is started, the anesthetic liquid inside the storage tank 11 can be used to perform local anesthesia on the patient through the connecting pipe 21 and the spray pipe 26. When it is necessary to clean the inside of the liquid storage tank 11, rotate the sealing cover 14 to drive the sealing gasket 15 and the fixing plate 16 to rotate, so that the upper surface of the fixing plate 16 is separated from the lower surface of the limiting plate 13, and the sealing cover 14 can be removed to clean the inside of the liquid storage tank 11. After cleaning, the lower surface of the sealing cover 14 is attached to the upper surface of the liquid storage tank 11, and the lower surface of the upper end of the sealing gasket 15 is attached to the upper surface of the limiting plate 13, and the fixing plate 16 is inserted into the inside of the limiting plate 13. Then, rotate the sealing cover 14 so that the upper surface of the fixing plate 16 is attached to the lower surface of the limiting plate 13, thereby fixing the position of the sealing cover 14. The above is the entire working principle of this utility model.
