Abstract
The present invention provides a vaginal administration apparatus, which relates to a medical apparatus for curing gynecologic diseases. The vaginal administration apparatus includes an outer tube and a pushing ram, which extends into the inside of the outer tube and can relatively move towards the outer tube. The front end of the outer tube is provided with a cylindrical medicine cavity, which has a bigger diameter and can contain a medicament. The caudal end of the outer tube is provided with a retainer ring. The vaginal administration apparatus is characterized in that a medicine claw is arranged at the front end of the pushing arm. The medicine claw consists of more than two petaloid memory metal coupons. When the medicine claw is inside the medicine cavity, under the affect of the medicine cavity wall, each memory metal coupon folds to be a cystic form; when the medicine claw extends outside the medicine cavity, the memory metal coupons automatically open. The caudal end of the pushing arm is provided with a pushing plate. A compression spring is mounted on the pushing arm between the retainer ring and the pushing plate. Under the effect of the compression spring, the medicine claw is inside the medicine cavity, and the pushable distance of the pushing plate is longer than the medicine cavity length. The present invention has the advantages of wide application range, simple structure and convenient self administration.
Description
Affiliated technical field
The present invention relates to a kind of medical apparatus for the treatment of gynaecopathia, a kind of specifically gynecological's administrator of vagina medicinal being sent into vagina or cervix uteri.
Background technology
To the intravaginal dispenser is the conventional means of treatment intravaginal disease, and Amino-Cerv mostly is tablet, suppository and powder at present.For tablet and suppository, traditional vagina application method is to adopt finger to push, and this kind drug delivery mode exists because of factors such as finger length cause medicine being sent into treatment position, thereby influences the defective of therapeutic effect; Simultaneously, do not note slightly also causing drug contamination easily, cause vaginal infection indirectly.For powder, spraying tool commonly used is lamellar or spoon shape administrator, and its defective is that drug delivery process Chinese medicine loses easily, and sufferer can't self-administration.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of tablet, suppository and powder of can being applicable to simultaneously is provided, applied widely, but the sufferer self-administration, the vaginal administration device of health easy to use.
Technical solution of the present invention is: vaginal administration device comprises outer tube and pushing ram, and pushing ram stretches in outer tube inside, and can move relative to outer tube; The outer tube front end is provided with the cylindric medicine chamber of big slightly the held medicament of diameter, and the outer tube tail end is provided with back-up ring; It is characterized in that: the pushing ram front end is provided with the medicine pawl, and the medicine pawl is made up of the flap memory metal sheet more than two, when the medicine pawl is in the medicine intracavity, under the effect of medicine chamber wall, each memory metal sheet closes up into cryptomere, and in the time of outside the medicine pawl stretches out the medicine chamber, memory metal sheet opens automatically; The pushing ram tail end is provided with pushing plate, is with the compression spring on the pushing ram between back-up ring and the pushing plate, and under the effect of compression spring, the medicine pawl is in the medicine intracavity, but the advance distance of pushing plate is greater than the medicine cavity length.
For guaranteeing that medicament can drop to the affected part smoothly from the medicine pawl, pushing ram is designed to the tubulose of hollow, also comprises a boosting bar that can move with respect to pushing ram in the pushing ram, the front end of boosting bar is for pushing away the medicine plate, tail end is a pushing assisted plate, a projection is arranged on the boosting bar, a shallow slot is arranged, in the time of in projection falls into shallow slot on the pushing ram inwall, push away the medicine plate and be positioned at the pushing ram top, promote pushing assisted plate and make projection skid off shallow slot, send before pushing away the medicine plate, play the effect that helps medicament to come off.
The present invention's medicament is that lamellar, bolt shape or powdery all can be clipped in the medicine pawl easily, during use, before at first outer tube being extend into the vaginal treatment position, promote pushing ram then, the messenger drug pawl stretches out the medicine chamber, and the medicine pawl opens automatically, promotes the boosting bar again, medicine is fallen on the treatment position exactly, has advantage applied widely, simple in structure, that make things convenient for self-administration.Smooth, the suitable length of outer tube of the present invention has not only alleviated the subject discomfort sense, and special-purpose medicine chamber and medicine pawl can reduce the secondary pollution of medicament, thereby helps the treatment of gynaecopathia.
