Problems solved by technology

[0007] The present invention solves the defect that liquid drugs cannot be used in the existing cervical drug forms (suppositories or gels), provides a cervical drug device, makes it possible to use liquid drugs, and avoids the matrix outflow after the drug dissolves in the past. Discomfort, while reducing the drug production process, reducing energy consumption, saving costs
[0008] The present invention also solves the defect that it is difficult to correctly act on the part of the cervix in the existing cervical drug administration method, and most of them are wasted halfway. Waste, open after reaching the cervical medication site, and directly act on the cervical part to improve the efficacy of the drug and reduce the course of treatment

Embodiment 1

[0028] Embodiment 1: a kind of cervical applicator (see attached figure 1 ), including an ellipsoidal accommodation chamber 1, the bottom of which is connected with a sleeve 3. The accommodating chamber is a hollow structure surrounded by five outer petals 2. A cotton wool pad 5 with medicine is placed inside the accommodating chamber, and the outside of the accommodating chamber is smooth. The end of the sleeve is provided with a hinge seat, and the lower part of the outer petal is provided with a hinge shaft. The joint between the outer petal and the end of the sleeve is formed by the cooperation of the hinge seat and the hinge shaft. There is an actuator for expanding the outer flap. Adjacent outer petal edges overlap each other in turn, that is, among the two side edges of all outer petals, one side edge is covered by the outer petal edge where the side edge is located, and the other side edge covers the outer petal where the side edge is located the edge of.

Embodiment 2

[0032] Embodiment 2: a kind of cervical applicator (see attached Figure 5 ), the difference from Example 1 is that: the inner wall of the outer valve is provided with a hook 6, the position of the hook is in the middle of the inner wall of the outer valve, and the elastic ring 8 is arranged on the cotton pad, and the hook hooks the elastic ring of the cotton pad (see attached image 3 ). The outer flap deployment mechanism includes a push rod 4 which is arranged in the sleeve and can move along the sleeve axis, and a reset part which drives the outer flap to expand or close as the push rod moves, and a locking mechanism is arranged between the push rod and the sleeve. The end of the outer petal is fixed with a handle 10, the handle is inclined to the axis of the push rod, and the top part of the push rod is fixed with a connecting piece 12, the diameter of the connecting piece is greater than the diameter of the push rod, and the outer periphery of the connecting piece is in ...

Embodiment 3

[0034] Embodiment 3: a kind of cervical applicator (see attached Figure 6), the top of the push rod is fixed with a connecting piece, the connecting piece is perpendicular to the push rod, and the diameter of the connecting piece is larger than that of the push rod. The side of connecting piece is fixed with hinge seat, and the inwall of outer petal is fixed with hinge seat near the hinge position, and connecting rod 13 is connected between two hinge seats. The length of the connecting rod ensures that after the push rod moves outward, the outer petal can rotate around the hinged part between the outer petal and the sleeve tube under the action of the connecting rod and expand to a suitable size.

[0035] The push rod is pulled down, and the connecting piece pushes the outer petal to rotate around the hinged part through the connecting rod and expand until it expands to a suitable size. The outer flap can be fixed by fixing the push rod and the sleeve. Push up the push rod ...

Abstract

The invention relates to a cervix uteri medicine applicator which comprises a containing cavity defined by multiple outer sections capable of being unfolded. Medicine cotton with medicine is placed in the containing cavity and connected with the inner wall of the containing cavity. The lower portions of the outer sections are provided with a sleeve and an outer section unfolding execution mechanism is arranged between the outer sections and the sleeve. The medicine is protected before the applicator reaches the medicine application position, the medicine is prevented from being wasted halfway and correctly acts on the cervix uteri portion, and therefore the curative effect of the medicine is guaranteed. Dosage forms of a plug form and a gel form of traditional cervix uteri medicine application are broken through and it is made possible that cervicitis is treated through liquid medicine.

Description

technical field [0001] The invention relates to a drug delivery device, in particular to a cervical applicator which is convenient for placing medicine at the position of the cervix. Background technique [0002] Due to its anatomical location and histological characteristics, the cervix is ​​a predilection site for obstetrics and gynecology diseases. For example, cervical inflammation (cervical erosion) and cervical intraepithelial neoplasia are the most common obstetrics and gynecology diseases. [0003] The cervix is ​​mainly composed of fibrous tissue and a small amount of smooth muscle and elastic connective, with less blood supply, it is difficult to achieve effective drug concentration in the local cervix with systemic medication (oral, intravenous), so the clinical efficacy of drugs is poor. [0004] At present, local treatment is often used clinically. Physical methods include: freezing, electrocautery, laser, circumcision, conization, etc., but these are invasive t...
