Abstract

The invention discloses a porous needle. The porous needle comprises a needle tube and a needle handle communicated with the porous needle. At least one hole is arranged in the tube wall of the needle tube; the distance from the hole, closest to the needle handle, to the needle handle is equal to the thickness of a penicillin bottle rubber plug. Utilizing the porous needle, the needle tube is inserted into the penicillin bottle rubber plug until the needle handle contacts with the outer surface of the rubber plug when medicine is dispensed; at that time, holes on the needle tube enter the inside of a penicillin bottle and at least one hole contacts with the rubber plug. Because of the inertia effect when a needle is thrusted and the tension effect when medicine liquid is in the needle body, agentia inside the penicillin bottle does not overflow from the hole in the tube wall. Liquid is injected into the penicillin bottle through the porous needle, and the agentia inside the penicillin bottle is mixed. In the suction process, the medicine liquid is concentrated in the upper part of the rubber plug because the penicillin bottle is placed inversely; finally the sucked medicine liquid is pulled away from the penicillin bottle through the hole located below the liquid level and the hole contacting with the rubber plug. The porous needle has the advantages of being simple in structure, convenient to manufacture, and being capable of fully sucking the medicine liquid in the penicillin bottle.

Description

technical field

[0001] The invention relates to the technical field of medical equipment, in particular to a porous needle, a medicine dispensing device and a medicine dispensing method. Background technique

[0002] A vial is a small glass container used to hold medicinal liquid. Its structure includes a bottle body and a bottle head, and a bottleneck located in the concave part between the bottle body and the bottle head. The capacity is generally 1-20ml, and it is generally used for injection medicinal liquid Or powder, the bottle cap of the bottle head is generally made of rubber, and a layer of metal aluminum foil is also set outside the rubber to seal.

[0003] The patent application with the application number CN201610317078.5 discloses a vial dispensing device and dispensing method, which realizes the automatic dispensing of vials, can effectively avoid the reflux of medicinal liquid, effectively reduces labor intensity, and has high dispensing efficiency, safety and...
