Abstract

A capsule wall-breaking extrusion tube, which relates to a drug delivery device. A conical head (1) is provided at one end of the drug delivery tube (6), and a conical pointed cavity (2) is arranged inside the conical head, from the conical pointed cavity to the delivery device. The other end of the drug tube is provided with a through hole (5), and the conical head is provided with a drug outlet (4) through the end of the through hole near the two sides of the drug delivery tube, and the cylindrical piston (11) is in the through hole. One end of the cylindrical piston is provided with a conical tip (10) matching the structure of the conical tip cavity, one end of the push-pull rod (13) is connected to the other end of the cylindrical piston, and a sealing ring (9) is provided on the outer edge of the cylindrical piston. The sealing ring The outer edge surface and the through hole are interference fit; in the present invention, the middle part of the capsule is placed in the through hole, and the two ends of the capsule are respectively placed in the drug outlet, and after the drug delivery tube pushes the capsule directly to the lesion, it is pierced by the conical point of the cylindrical piston. Break and squeeze the capsule, and the broken capsule will flow out from the drug outlet to reach the lesion.

[0002] In the treatment of gynecological diseases or anal diseases, it is necessary to deliver the medicine deep into the vagina or anus; the capsule is a capsule made of gelatin, cellulose or polysaccharide as the main component, and the capsule can be kept easily It is the active ingredient of medicines, and can be loaded into various medicines in powder and liquid form. The protection of capsules not only ensures that the properties of medicines are not destroyed, but also protects the effective absorption of organs. Therefore, many medicines used in the vagina or anus The drug is packaged in capsules; however, how to deliver the capsule deep into the vagina or anus has always been a technical problem; the current method requires the user to insert the drug with his fingers, so that on the one hand, the depth of delivery cannot meet the requirements, and on the other On the one hand, there will be hygienic problems; especially some people with limited mobility need the assistance of their children to deliver medicines; or nurses and senior care workers assist in delivering medicines, so that the mental and psychological pressure of medical staff or family members is extremely high, and liquid medicine capsules are used.
