[0035] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0036] like Figures 1-4 As shown, a gynecological gel applicator includes an applicator cartridge 5 with an applicator port 2 and a pusher mechanism that moves axially along the inner wall of the cartridge 5. By pushing the pusher mechanism with a finger, the gel medication in the cartridge 5 can be pushed out from the applicator port 2 and applied to the patient for therapeutic purposes.

[0037] It also includes a limiting component 6, which includes a limiting ring 61 sleeved on the outer wall of the drug delivery cylinder 5. An elastic element is provided on the side of the limiting ring 61 away from the drug delivery port 2. A pressing component 7 is movably provided on the outer wall of the drug delivery cylinder 5 to drive the elastic element to contact and press against the outer wall of the drug delivery cylinder 5. The limiting ring 61 is moved to a suitable position on the outer wall of the drug delivery cylinder 5, and then the pressing component 7 is moved to the outside of the elastic element, generating an inward contraction force on the elastic element. At this time, the elastic element will contract inward and contact and squeeze with the outer wall of the drug delivery cylinder 5, which can increase the frictional resistance between the limiting ring 61 and the drug delivery cylinder 5, so that the limiting ring 61 can be stably fixed at any position of the drug delivery cylinder 5. Thus, the limiting ring 61 can form a limiting and blocking structure at different positions of the drug delivery cylinder 5, thereby limiting the drug delivery insertion depth of the drug delivery cylinder 5, so that the drug delivery cylinder 5 can accurately deliver the gel to different depths in the patient's body, improving the accuracy of drug delivery.

[0038] The end of the drug delivery cartridge 5 is provided with a sealing component 10. Removing the sealing component 10 facilitates the introduction of gel medication into the drug delivery cartridge 5, while covering the sealing component 10 can seal the drug delivery cartridge 5 and prevent the gel medication from leaking out.

[0039] The elastic element includes a spring ring 62 disposed on the limiting ring 61. The inner wall of the spring ring 62 is provided with contacts 63, which are arranged in a ring structure on the inner wall of the spring ring 62. The length of each contact 63 is greater than the distance between the spring ring 62 and the outer wall of the administration cartridge 5. The pressing assembly 7 includes a movable ring 71 disposed on the outer wall of the administration cartridge 5. A pressing ring 72 is disposed on the movable ring 71 and fitted onto the outer wall of the spring ring 62. When the limiting ring 61 moves to a suitable position on the administration cartridge 5, it pushes the movable ring 71 to press against the spring ring 62 on the administration cartridge 5. The movement of the clamping ring 72 causes the clamping ring 72 to move to the outside of the elastic ring 62. As the overlapping area of ​​the clamping ring 72 and the elastic ring 62 increases, the elastic ring 62 will continuously contract and deform inward, causing the frictional resistance between the contact 63 and the drug delivery cylinder 5 to gradually increase. This can clamp and reinforce the position of the limiting ring 61, ensuring that the limiting ring 61 can be stably fixed at any position of the drug delivery cylinder 5. Thus, the limiting ring 61 can form a limiting and blocking structure at different positions of the drug delivery cylinder 5, thereby limiting the drug delivery insertion depth of the drug delivery cylinder 5.

[0040] The sealing assembly 10 includes a sealing cap 101, on which a screw ring 102 is disposed on the outer wall of the administration cartridge 5. The sealing cap 101 is provided with a finger groove 103. The screw ring 102 is fixed to the outer wall of the administration cartridge 5, so that the sealing cap 101 seals the opening of the administration cartridge 5 and allows the finger to be pressed in the finger groove 103, which can provide a stable operation for the finger and the administration device and prevent the administration from slipping out of the hand.

[0041] The drug delivery mechanism includes a push rod 9 that passes through the sealing cap 101. One end of the push rod 9 is provided with a drug delivery head 8 that extends into the drug delivery cylinder 5, and the other end is provided with a handle 11. By pressing the handle 11, the push rod 9 is driven to move inside the drug delivery cylinder 5, and the drug delivery head 8 comes into contact with the gel drug inside the drug delivery cylinder 5, so that the gel drug can be pushed out from the drug delivery port 2.

[0042] A plug 3 is embedded in the inner wall of the administration port 2 to seal the administration port 2 and prevent the gel in the administration tube 5 from leaking out.

[0043] It also includes a sealing cap 4, which includes a flexible tube 41 sleeved on the outer wall of the drug delivery cylinder 5. An arc-shaped sealing cover 42 is provided on the flexible tube 41. The sealing cover 42 can provide overall sealing protection for the opening of the drug delivery device, preventing the drug delivery device from falling to the ground and causing the drug delivery port 2 to be contaminated or damaged.

[0044] The outer wall of the drug delivery cylinder 5 is provided with a scale line 1 along its axial direction to indicate the position of the limiting ring 61, thereby facilitating and accurately adjusting the position of the limiting ring 61 and achieving drug delivery at different depths.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
