Description

Technical Field

[0001] The utility model relates to the field of medical devices, and more specifically to a disposable medication dispenser for gynecology. Background Art

[0002] Many gynecological conditions are treated through vaginal administration, which can directly kill or inhibit pathogenic microorganisms that parasitize the vagina. It can also reduce inflammation, relieve itching, reduce pain, promote tissue regeneration, and protect and repair damaged mucosa. Traditional vaginal administration typically involves formulating drugs into solid dosage forms such as tablets, suppositories, or films. A vaginal speculum is used to hold the vagina open, and the drug is inserted with forceps, or by the doctor or patient using their fingers. Gels, ointments, and creams are then delivered deep into the vagina using a dispenser.

[0003] The vaginal drug delivery devices currently on the market are usually cylindrical in shape, which makes it difficult to enter the drug delivery area and fails to improve patient comfort. At the same time, some push rods are designed to be thin, which makes it inconvenient to push the push rods when taking the medicine and is easy to slip. Utility Model Content

[0004] The purpose of the utility model is to address the deficiencies of the existing technology and provide a disposable gynecological applicator. The conical section and groove designed on the tube body can discharge the air in the body when it is pushed into the vagina, while reducing the squeezing feeling when the vagina is stretched, increasing the comfort during use, and the trumpet-shaped push rod makes pushing more convenient.

[0005] The technical solutions of this utility model are as follows:

[0006] A disposable gynecological drug dispenser includes a medicine tube, a piston slidably arranged in the medicine tube, and a push rod connected to the piston. The end of the medicine tube is provided with a drug delivery port, and the drug delivery port is covered with a cap. The front end of the medicine tube is provided with a conical section, and the conical section is provided with a plurality of grooves along the circumferential direction.

[0007] As a preference, the number of the grooves is set between 4 and 6, and the groove structure is an elliptical arc structure with a length between 2 cm and 4 cm.

[0008] As a preference, a pull rod is provided on the cap.

[0009] As a preference, a sealing ring is provided on the push rod.

[0010] As a preference, the inner cavity of the medicine tube is cylindrical and the diameter increases first and then decreases from the top to the tail of the inner cavity.

[0011] As a preference, the diameter of the push rod is smaller than the diameter of the medicine tube and the bottom of the push rod is a trumpet-shaped structure.

[0012] As a preference, the bottom of the medicine tube is configured as a trumpet-shaped structure.

[0013] The beneficial effects of the present invention are:

[0014] 1. The conical section and groove provided in the present invention can reduce the discomfort of the patient when the medicine tube goes deep into the vagina, and alleviate the squeezing feeling of the vaginal wall being stretched. At the same time, the groove can also discharge air when the medicine tube goes deep into the vagina, making the insertion smoother.

[0015] 2. The utility model also reduces the friction force exerted on the push rod when it is pushed by means of a push rod having a diameter smaller than the diameter of the medicine tube and a trumpet-shaped structure at the bottom of the push rod. The diameter of the push rod is smaller than the diameter of the inner cavity of the medicine tube. When the piston slides, the outer wall of the push rod does not contact the inner wall of the medicine tube, making pushing more convenient. In addition, the trumpet-shaped structure at the bottom of the push rod makes it less likely to slip when pushed. The sealing ring slides in cooperation with the inner wall of the medicine tube. The sealing ring is used to seal and prevent leakage of residual medicine on the inner wall of the medicine tube when the piston is pushed.

[0016] In summary, the utility model has the advantages of high comfort and convenient pushing, and is suitable for the field of medical devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present utility model are clearly and completely described below with reference to the accompanying drawings.

[0023] Example 1

[0024] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] like Figures 1 to 3As shown, a disposable gynecological applicator includes a medicine tube 1, a piston 2 slidably arranged in the medicine tube 1, and a push rod 3 connected to the piston 2. The end of the medicine tube 1 is provided with a medicine delivery port 4, and the medicine delivery port 4 is covered with a cap 5. The front end of the medicine tube 1 is provided with a conical section 6, and the conical section 6 is provided with a plurality of grooves 7 along the circumferential direction.

[0026] like Figure 3 As shown, the number of grooves 7 is set between 4 and 6, and the structure of the grooves 7 is an elliptical arc structure and the length is between 2 cm and 4 cm. When in use, the cap 5 is removed, and the conical section 6 and the grooves 7 penetrate into the vagina to reduce the patient's discomfort and alleviate the squeezing feeling of the vaginal wall being stretched. At the same time, the grooves 7 can also discharge air when penetrating, making the penetration smoother.

[0027] like Figure 2 As shown, a pull rod 8 is provided on the cap 5, and the pull rod 8 is used to facilitate the removal of the cap 5.

[0028] like Figure 3 As shown, a sealing ring 9 is provided on the push rod 3, and the sealing ring 9 is in sliding cooperation with the inner wall of the medicine tube 1. The sealing ring 9 is used to seal and prevent the residual medicine on the inner wall of the medicine tube 1 from leaking when the piston 2 is pushed.

[0029] like Figure 3 As shown, the inner cavity of the medicine tube 1 is cylindrical and the diameter from the top of the inner cavity to the tail increases first and then decreases. By increasing first and then decreasing, the applicator can effectively open the vagina and reduce patient discomfort.

[0030] like Figure 3 As shown, the diameter of the push rod 3 is smaller than the diameter of the medicine tube 1 and the bottom of the push rod 3 is a trumpet-shaped structure. In order to reduce the friction force applied to the push rod 3 when pushing, the diameter of the push rod 3 is smaller than the diameter of the inner cavity of the medicine tube 1. When the piston 2 slides, the outer wall of the push rod 3 does not contact the inner wall of the medicine tube 1, making pushing more convenient. In addition, the trumpet-shaped structure at the bottom of the push rod 3 makes it less likely to slip when pushing.

[0031] like Figure 3 As shown, the bottom of the medicine tube 1 is configured as a trumpet-shaped structure to facilitate the movement of the push rod 3 in and out.

[0032] Working process

[0033] The medical staff or the patient holds the medicine tube 1, removes the cap, and starts to penetrate into the vagina from the conical section 6. After reaching the position, the push rod 3 is pushed to inject the medicine in the medicine tube 1 into the vagina for treatment, and then the medicine tube 1 and the push rod 3 are removed from the vagina together.

[0034] In the description of the present invention, it should be understood that the terms "front and back", "left and right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the equipment or components referred to must have a specific direction, be constructed and operated in a specific direction.
