Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a portable anesthetic spray delivery device. Background Technology
[0002] Drug delivery devices, as crucial instruments in the medical field, have the core function of precisely and efficiently delivering various drugs to specific parts of the human body to ensure that the drugs can exert their full effect. Due to the rich variety of drug dosage forms, including liquids, powders, gels, and solids, and the different routes of administration, drug delivery devices are used in various ways.
[0003] A spray drug delivery device is a specialized device that transforms liquid medication into tiny droplets and delivers them precisely to specific areas of the body in a spray form. Its working principle is based on mechanisms such as pressing, compression, or ultrasonic vibration. When operated by the user, the internal structure causes the medication to be sprayed out in a mist form through a specially designed nozzle. In applications, nasal sprays are commonly used to relieve symptoms such as nasal congestion caused by rhinitis and colds, as the medication acts directly on the nasal mucosa. Oral sprays can be used to treat oral inflammation and relieve throat discomfort; for example, watermelon frost spray quickly forms a drug coating on the surface of the mouth and throat. Skin sprays are suitable for treating local skin diseases or wound care, as the drug droplets evenly cover the skin, promoting absorption. Compared to other drug delivery methods, spray drug delivery has many advantages. It allows for more even distribution of the drug at the site of action, improves drug absorption efficiency, and reduces the amount of medication required.
[0004] However, some existing anesthetic spray dispensers lack effective protective mechanisms during daily storage or carrying, making them prone to accidental activation of the press button. These dispensers typically only have a simple press-type dispensing structure, which means that the press button can be triggered unintentionally, such as when it is placed in a pocket or bag and squeezed by other objects, causing unnecessary spraying of anesthetic spray. This not only wastes the medication but can also cause danger in inappropriate situations and even affect the dosage accuracy and efficacy of subsequent normal use due to premature consumption of the medication. Therefore, to address these shortcomings, a portable anesthetic spray dispenser is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a portable anesthetic spray applicator, which aims to improve the problem that some existing anesthetic spray applicators cannot prevent accidental activation of the pressing block.

[0032] 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.
[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a portable anesthetic spray applicator, comprising a medicine bottle 1, which serves as the core drug storage structure of the entire anesthetic spray applicator. A spraying assembly is provided on the top of the medicine bottle 1. A sliding rod 7 is slidably connected inside the spraying assembly. The sliding rod 7 is rotatably connected to the inside of the nozzle 3. A fixing plate 8 is fixedly connected to the outside of the sliding rod 7. The fixing plate 8 can be used to drive the spring 9 to compress. The spring 9 is sleeved on the outside of the sliding rod 7. One end of the spring 9 is fixedly connected to the front side of the positioning ring 11, and the other end of the spring 9 is fixedly connected to the inside of the nozzle 3. During the operation of the applicator, when the pull plate 12 is pulled to move the sliding rod 7, the spring 9 will be compressed and store elastic potential energy. When it is necessary to unlock the pressing block 5, the pull plate 12 is released, the spring 9 releases the stored energy, pushes the sliding rod 7 and the connected parts to reset, so that the locking post 14 is engaged in the locking groove 15, and the unlocking action is completed. The spraying assembly has a sliding groove 10 inside, which provides a track for the sliding and rotation of the fixed plate 8 and the positioning ring 11. The fixed plate 8 is externally slidably connected to the inside of the sliding groove 10.
[0034] A positioning ring 11 is rotatably connected to the outside of the sliding rod 7. The positioning ring 11 assists in the movement and positioning of the fixed plate 8. The outside of the positioning ring 11 is slidably connected to the inside of the slide groove 10. A pull plate 12 is fixedly connected to the front side of the sliding rod 7. By pulling the pull plate 12, the sliding rod 7 can be moved and rotated. A cam 13 is fixedly connected to the outside of the sliding rod 7. When the sliding rod 7 rotates, the cam 13 moves in a circular motion. A locking pin 14 is fixedly connected to the rear side of the cam 13. The outside of the locking pin 14 is slidably connected to the inside of the nozzle 3. The external sliding connection is inside the pressing block 5. When the pull plate 12 is pulled, the sliding rod 7 moves, which in turn causes the cam 13 to rotate. The locking pin 14 will slide out from inside the pressing block 5 and the nozzle 3 under the push of the cam 13, and in subsequent operations, it will align with the inside of the locking groove 15. Finally, under the elastic force of the spring 9, it will lock into the locking groove 15, thus unlocking the pressing block 5. The inside of the spraying assembly is provided with a locking groove 15. The external sliding connection of the locking pin 14 is inside the locking groove 15. The locking groove 15 is used to cooperate with the locking pin 14 to unlock and lock the pressing block 5.
[0035] Reference Figure 1 , Figure 4 and Figure 5 The spraying assembly includes a sealing shell 2, which plays a crucial role in sealing and connecting. The bottom of the sealing shell 2 is threadedly connected to the top of the medicine bottle 1. A sealing ring 20 is fixedly connected inside the sealing shell 2. The main function of the sealing ring 20 is to fill the gap between the medicine bottle 1 and the spray head 3 when they are connected, forming a tight seal to prevent drug leakage and outside air from entering the medicine bottle 1. A compression ring 21 is fixedly connected to the top of the medicine bottle 1. When the medicine bottle 1 and the sealing shell 2 are connected by threads, the compression ring 21 will gradually compress the sealing ring 20 as the connection tightens, causing the sealing ring 20 to deform and fit more tightly in the gap between the medicine bottle 1 and the sealing shell 2, thereby greatly enhancing the sealing performance of the connection. A spray head 3 is fixedly connected to the top of the sealing shell 2. The spray head 3 is the key structure for spraying the drug in the form of a spray. A fixed shaft 4 is fixedly connected to the left side of the inside of the spray head 3. The fixed shaft 4 provides a stable support point for the rotation of the pressing block 5. The pressing block 5 is rotatably connected to the outside of the fixed shaft 4.
[0036] When needed, pressing block 5 rotates around fixed axis 4, thereby pushing the drug out of nozzle 3. Atomizing head 6 is fixedly connected to the left side of nozzle 3. When the drug enters atomizing head 6 through nozzle 3, it is further broken into extremely fine droplets under the action of micropores or swirling flow. A fixing ring 16 is fixedly connected to the outside of the medicine bottle 1, serving to assist in fixation and enhance structural stability. A handle 17 is fixedly connected to the outside of the medicine bottle 1, allowing the user to easily pick up and operate the drug delivery device using the handle 17, whether in clinical use or... In daily life, the handle 17 greatly improves the convenience of using the medication applicator. The fixing ring 16 is externally fixedly connected to the card plate 18. When the medication applicator is not in use, the user can hang the medication applicator in a fixed position, such as a hook on the wall or other suitable hanging device, through the card plate 18, which saves space and is easy to store. At the same time, it can also effectively prevent the medication applicator from being lost or damaged. The card plate 18 has a positioning groove 19 inside. The positioning groove 19 can keep the medication applicator in a stable position when it is hung, avoiding shaking or falling. It also makes it convenient for the user to accurately hang the medication applicator in a suitable position.
[0037] Working principle: When using this anesthetic spray applicator, pulling the pull plate 12 causes the sliding rod 7 to shift, which in turn causes the fixed plate 8 and positioning ring 11 to slide inside the slide groove 10. This compresses the spring 9, causing the locking pin 14 to slide out from inside the pressing block 5 and nozzle 3. Then, rotating the pull plate 12 causes the sliding rod 7 to rotate, which in turn causes the fixed plate 8 to rotate inside the slide groove 10. This causes the cam 13 to perform a circular motion, aligning the locking pin 14 with the inside of the locking slot 15. Finally, releasing the pull plate 12 allows the applicator to... The elastic force of the spring 9 causes the locking post 14 to engage inside the locking groove 15, thereby releasing the lock on the pressing block 5. At this time, the pressing block 5 can be pressed to make the pressing block 5 rotate around the fixed shaft 4, thereby locking the pressing block 5 to prevent accidental contact. Through the cooperation of the sealing ring 20 and the squeezing ring 21, the connection and sealing between the medicine bottle 1 and the nozzle 3 can be greatly improved. At the same time, the handle 17 makes it easy to hold the medicine dispenser. When not in use, the medicine dispenser can be suspended in a fixed position with the help of the locking plate 18 and the positioning groove 19, thereby achieving portability.
[0038] 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.
