A capsule automatic wall-breaking push device

Abstract

A capsule wall-breaking automatic pushing device, relating to a drug delivery device, one end of a drug delivery tube (5) is connected to the large end of a conical head (3) whose diameter changes from large to small, and is circled on the inner surface of the small end of the conical head A plurality of V-shaped protrusions (2) are arranged at the medicine port (1), a middle finger ring (7) and a thumb ring (8) are respectively arranged on both sides of the other end of the medicine delivery tube, and one end of the push-pull rod (13) An index finger ring (15) is provided, the other end of the push-pull rod is connected to the large-diameter end face of the conical piston (11), and a sealing ring (9) is arranged on the large-diameter end outer edge of the conical piston, which is located in the inner chamber of the drug delivery tube. The outer edge surface of the conical piston in (6) matches the conical chamber (4) in the conical head; the present invention is by placing the capsule in the conical head of the drug delivery tube, and the capsule is directly pushed into the conical head by the drug delivery tube. After the lesion is located, the V-shaped protrusion squeezed by the conical piston will break the capsule and flow out from the drug outlet.

[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.
