Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of medicine application and care devices, and more specifically, it relates to a medicine application and care device. Background Technology
[0002] A gynecological medication applicator is a medical aid specifically designed for the treatment of female reproductive system diseases. It is primarily used to accurately and safely deliver medication to the vagina or cervix. The applicator typically includes a cartridge, plunger, tubing, and anti-backflow device; some products also feature spray or sustained-release functions. Its advantages include avoiding the inconvenience and cross-infection associated with manual application, improving medication accuracy and efficacy, and enhancing patient comfort and treatment adherence.
[0003] Most medication application devices are now reusable. After use, users need to clean the device. Direct cleaning can easily leave residual medication or contaminants at the medication inlet, which can easily breed bacteria and affect proper medication application.
[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a medicine application device, in order to achieve a more practical value. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a medicine application device, which is achieved by the following specific technical means:
[0006] A medication application device includes a cylindrical body with a medication storage groove on one side, the groove extending through both sides of the cylindrical body. A shielding plate is provided on one side of the cylindrical body, and a through groove is provided on the shielding plate corresponding to the medication storage groove, the through groove communicating with the storage groove. A piston is movably disposed within the storage groove. A connecting rod is provided on the side of the piston away from the shielding plate, and a push block is provided on the side of the connecting rod away from the storage groove. An installation block is provided on the side of the cylindrical body adjacent to the shielding plate, and a plurality of threaded blocks are provided on the surface of the installation block. A disposable contact sleeve is threadedly connected to the installation block through the threaded blocks.
[0007] Furthermore, the disposable contact sleeve has an injection groove corresponding to the through groove.
[0008] Furthermore, the inner wall of the disposable contact sleeve is provided with threaded grooves corresponding to several threaded blocks.
[0009] Furthermore, a rubber ring is fitted on the outer side of the piston.
[0010] Furthermore, the cylinder body is provided with a lever block on the side near the push block.
[0011] Furthermore, an observation slot is provided on one side of the cylinder, and an acrylic observation plate is provided in the observation slot.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] In this invention, the installation block, threaded block, and threaded groove work together to facilitate the installation and replacement of disposable contact sleeves, ensuring safety and hygiene. The observation slot and acrylic observation plate work together to effectively assist users in observing the residual liquid in the medicine storage tank. Attached Figure Description

[0023] Example:
[0024] As attached Figure 1 To be continued Figure 4 As shown:
[0025] This utility model provides a medication application device, including a cylindrical body 1. A medication storage groove 2 is provided on one side of the cylindrical body 1, and the medication storage groove 2 extends through both sides of the cylindrical body 1. A shielding plate 3 is provided on one side of the cylindrical body 1. A through groove 4 is provided on the shielding plate 3 corresponding to the medication storage groove 2, and the through groove 4 communicates with the medication storage groove 2. A piston 5 is movably arranged in the medication storage groove 2. A connecting rod 6 is provided on the side of the piston 5 away from the shielding plate 3. A push block 7 is provided on the side of the connecting rod 6 away from the medication storage groove 2. An installation block 8 is provided on the side of the cylindrical body 1 adjacent to the shielding plate 3. A plurality of threaded blocks 9 are provided on the surface of the installation block 8. A disposable contact sleeve 10 is threadedly connected to the installation block 8 through the threaded blocks 9.
[0026] The disposable contact sleeve 10 has a drug injection groove 11 corresponding to the through groove 4.
[0027] The inner wall of the disposable contact sleeve 10 is provided with threaded grooves 12 corresponding to several threaded blocks 9.
[0028] The piston 5 is fitted with a rubber ring 13 on its outer side.
