Integrated medicine dispensing mechanism used for powder injection bottles and medicine dispensing method

Abstract

The invention discloses an integrated medicine dispensing mechanism used for powder injection bottles and a medicine dispensing method. The medicine dispensing mechanism comprises an infusion bag needle and a powder injection bottle needle, wherein the infusion bag needle is a two-hole needle containing a through hole I and a through hole II; the through hole I and the through hole II are respectively connected with a catheter I and a catheter II; the powder injection bottle needle is a two-hole needle containing a through hole III and a through hole IV; the through hole III and the through hole IV are respectively connected with a catheter III and a catheter IV; a check valve I for fluid to flow from the catheter I to the catheter III is arranged between the catheter I and the catheter III; a check valve II for fluid to flow from the catheter IV to the catheter II is arranged between the catheter II and the catheter IV; an air tube is communicated in the middle of the catheter III; a check valve III is arranged on the air tube. The medicine dispensing mechanism and the medicine dispensing method have the beneficial effects that the medicine dispensing mechanism is in an integrated structure, can rapidly connect an infusion bag with a powder injection bottle once and enables the liquid medicine in the infusion bag to be smoothly injected into the powder injection bottle; meanwhile, the liquid medicine in the powder injection bottle can be rapidly infused into the infusion bag by starting an air pump; the medicine dispensing method is convenient in connection, is simple to operate and has the effects of greatly improving the medicine dispensing efficiency and avoiding liquid medicine loss.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an integrated dispensing mechanism and a dispensing method for powder injection bottles. Background technique [0002] The powder injection bottle is a small glass container used to hold liquid medicine. Its structure includes a bottle body and a bottle head, and a bottle neck 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 medicine. Liquid, the bottle cap of the bottle head is generally made of rubber, and a layer of metal aluminum sheet is set outside the rubber to seal. [0003] At present, when dispensing the powder injection bottle, the powder injection bottle is generally held in hand, the injection syringe with the liquid medicine is sucked in advance, inserted into the powder injection bottle, and then the medicine liquid is injected inward, the needle is pulled out, and shak...

Problems solved by technology

[0006] The purpose of the present invention is to: in the prior art, when the one-way valve type dispensing device is used for dispensing powder injection bottles, it needs to insert and pull out the needle twice or more, which not only troubles the operation, but also increases the dispensing time and affects the dispensing efficiency. , and it is easy to spray the liquid medicine, resulting in waste, inaccurate dispensing amount, and even damage to the needle, which increases the cost of dispensing. An integrated dispensing mechanism for powder injection bottles and a dispensing method of the dispensing mechanism are provided
