[0002] In the treatment of pharyngeal diseases, many patients require local drug delivery and secretion drainage through medical devices. Common pharyngeal drainage and drug delivery devices typically employ a fixed structure. While their design enables drug delivery and drainage, they still have some significant limitations and problems in practical use.

[0003] First, most existing pharyngeal drainage and drug delivery devices have a fixed structure, with the drug delivery port and drainage tube head usually designed as a single unit, making quick disassembly and replacement impossible. During long-term use, the drug delivery head is prone to bacterial growth due to drug residue or contact with the patient's mouth and pharynx, increasing the risk of device contamination. Because the drug delivery head is not detachable, the cleaning and disinfection process is complex, increasing the difficulty for medical staff and potentially leading to incomplete cleaning and cross-infection. Furthermore, the fixed structure limits the device's adaptability, meaning the type of drug delivery head cannot be adjusted according to different drugs or patient needs, affecting the accuracy of treatment efficacy. Therefore, to address these issues, a new pharyngeal drug delivery device is proposed. Utility Model Content

[0018] 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.

[0019] like Figures 1 to 4 As shown, this embodiment provides a pharyngeal medication delivery device, including a pharyngeal medication delivery device body 1. A medication delivery tube 2 is connected to the top of the pharyngeal medication delivery device body 1, and a medication delivery tube head 3 is inserted into one end of the medication delivery tube 2. An insertion groove 4 is formed at one end of the medication delivery tube 2, and a nesting rod 5 is fixedly connected to the outer wall of the medication delivery tube head 3, with the nesting rod 5 inserted into the insertion groove 4. To ensure a secure connection, a limiting groove 6 is formed on the outer wall of the nesting rod 5, a moving groove 7 is formed on the outer wall of the medication delivery tube 2, and a clamping block 8 is provided on the outer wall of the medication delivery tube 2. A limiting rod 9 is fixedly connected inside the clamping block 8, and the limiting rod 9 passes through the moving groove 7 and is inserted into the limiting groove 6, thereby limiting and fixing the medication delivery tube head 3. To enhance the fixing effect, a rotating rod 10 is fixedly connected to one end of the clamping block 8, and the two sides of the rotating rod 10 are rotatably connected to the outer wall of the medication delivery tube 2 via rotating shafts 11, with the rotating shafts 11 fixedly connected to the outer wall of the medication delivery tube 2.

[0020] In actual use of the device, when it is necessary to install the delivery tube head 3, first align the delivery tube head 3 with the delivery hose 2, and then insert the inserting rod 5 into the inserting groove 4. Subsequently, the user can rotate the clamping plate block 8 to make it fit against the outer wall of the delivery hose 2. At this time, the limiting rod 9 slides through the moving groove 7 and inserts into the limiting groove 6 to fix the delivery tube head 3. In this way, the connection between the delivery tube head 3 and the delivery hose 2 is more stable, avoiding the risk of loosening or falling off during use. Conversely, when it is necessary to disassemble the delivery tube head 3, the clamping plate block 8 can be rotated outward to pull the limiting rod 9 out of the limiting groove 6, thereby quickly and conveniently removing the delivery tube head 3 from the delivery hose 2, realizing the convenient plug-and-play operation.

[0021] The limiting groove 6 and the moving groove 7 correspond to each other, and the outer wall of the limiting rod 9 fits snugly against the inner wall of the moving groove 7. This structural design ensures a more stable insertion of the limiting rod 9 into the limiting groove 6, guaranteeing a stable connection between the drug delivery head 3 and the drug delivery hose 2, and further improving the reliability of the device. To further enhance the symmetry and stability of the device, the inserting rod 5, limiting groove 6, moving groove 7, clamping plate 8, limiting rod 9, rotating rod 10, and rotating shaft 11 are symmetrically arranged on the outside of the drug delivery hose 2. The limiting rods 9 on both sets of clamping plate 8 are simultaneously inserted into the corresponding limiting grooves 6 for fixation, further ensuring the stability of the drug delivery head 3 and the drug delivery hose 2 after installation, making the connection of the device more secure and reliable.

[0022] The rotating rod 10 and the rotating shaft 11 are elastically connected. This elastic connection structure allows the clamping plate block 8 to automatically fit against the outer wall of the delivery hose 2 during use, ensuring the normal operation of the delivery device. In actual operation, the elastic connection design allows users to install and disassemble more smoothly and flexibly, avoiding damage to the device caused by excessive force and ensuring the stability and reliability of the connection.

[0023] In addition, a scraping sleeve 12 is fixedly connected to the outer wall of the drug delivery head 3. The scraping sleeve 12 has a wedge-shaped cross-section and is arranged around the outer wall of the drug delivery head 3. The scraping sleeve 12 is designed to effectively scrape away the mucosa or secretions at the pharyngeal lesion during device operation, preventing secretions from blocking the effective drug delivery path. At the same time, in conjunction with the drug delivery function of the drug delivery head 3, it enables the drug to reach the affected area more accurately, improving the treatment effect.

[0024] One end of the delivery tube 3 is also equipped with a spray channel 13, which has a honeycomb-like design. This honeycomb spray channel design, through multiple small holes or channels, allows the medication to be evenly distributed over a wide pharyngeal area. Compared to the traditional single-nozzle design, the honeycomb structure has the advantage of effectively dispersing the drug flow, allowing the medication to be sprayed from multiple points, covering a larger area of ​​the pharynx. This design not only significantly increases the contact area of ​​the medication in the pharynx but also ensures that the medication acts evenly on the lesion area, thereby improving the therapeutic effect and reducing drug waste. At the same time, the honeycomb spray channel design also prevents drug backflow, effectively preventing reverse flow of medication caused by the patient swallowing or breathing, and maintaining the accuracy of drug delivery.

[0025] Another advantage of this honeycomb design is that it allows for a smoother spray of medication, preventing strong irritation to the patient's throat, making it particularly suitable for sensitive lesion areas. The porous structure of the spray nozzle also makes medication delivery more efficient, ensuring adequate coverage even with smaller doses and preventing excessive concentration in any one area. At the same time, the honeycomb porous design facilitates cleaning and maintenance, reducing the possibility of medication residue inside the spray nozzle and extending the device's lifespan.

[0026] Through the above design, the pharyngeal drug delivery device of the present invention not only achieves good structural stability and convenient assembly / disassembly, but also effectively improves the uniformity and efficiency of drug delivery, as well as patient comfort. This device is suitable for the treatment of various pharyngeal diseases requiring local drug delivery, and through its precise design, reduces operational complexity and patient discomfort.
