Suppository administration method and device

Abstract

The invention aims to provide a suppository administration method and device. The method comprises the steps of 1, inserting a positioning conical tube with a circular wing stop at the tail end into an administration part; 2, inserting an applicator conical tube from the tail end of the positioning conical tube, and defining the diameter of the fine end of the positioning conical tube as the length of the applicator conical tube extending into the administration part; 3, putting a suppository into the applicator conical tube; 4, inserting a push rod from the tail end of the applicator conicaltube, wherein one end of the push rod is provided with a hollow silica gel head, and when the diameter of the push rod is equal to the cross-sectional diameter of the applicator conical tube, the space occupied by the suppository at the front end of the applicator conical tube is completely filled with the hollow silica gel head through extrusion deformation of the applicator conical tube, so as to extrude the suppository to complete the operation. The problems of an existing suppository administration method that anal injury might be caused, the depth of administration is not easy to control,operation is not easy, and administration might be affected by the fact that medicine is fragile are solved, suppository administration is more accurate and simple, and medicine can be prevented frombeing broken.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a suppository administration method and device. Background technique [0002] Suppositories are solid dosage forms composed of drugs and matrix, which are specially used for local or systemic therapeutic effects in the human cavity. Suppositories are generally solid at room temperature. After being inserted into the cavity, they can quickly soften and release the drug effect under the action of body temperature. . It has the following advantages: the drug is not damaged by gastrointestinal pH or enzymes, and avoids the irritation of the drug to the stomach; it can avoid the first-pass damage of the drug by the liver when it is taken orally, and can also reduce the toxicity and side effects of the drug to the liver; rectal absorption There are fewer interfering factors than oral administration; the action time of suppositories is longer than that of ordinary oral tablets; rectal ad...
