Disposable split type sterile medicine dispensing infusion apparatus and disposable medicine dispensing infusion method

Abstract

The invention discloses a disposable split type sterile medicine dispensing infusion apparatus. The disposable split type sterile medicine dispensing infusion apparatus comprises a bottle stopper puncture device for insertion into an infusion bottle, wherein the bottle stopper puncture device comprises two inner pipelines, namely a first inner pipeline and a second inner pipeline, the bottle stopper puncture device is inserted into the infusion bottle, the lower end opening of the first inner pipeline is positioned on the bottle neck on the upper part of the infusion bottle, the lower end opening of the second inner pipeline is positioned at the bottle bottom at the lower part of the infusion bottle, the upper end opening of the first inner pipeline is connected with a first flexible pipe, and the upper end opening of the second inner pipeline is connected with a second flexible pipe; the first inner pipeline is taken as an air channel in the medicine dispensing process, and is also taken as a liquid medicine flow channel in the infusion process; the second inner pipeline is taken as a liquid medicine flow channel in the medicine dispensing process, and is taken as an air channel in the infusion process. According to the disposable split type sterile medicine dispensing infusion apparatus, through the combined use of medicine dispensing and infusion, the cost is reduced, and the waste is reduced; the repeated insertion of a needle tube or the bottle stopper puncture device is not needed, so that the falling scraps generated by puncturing a bottle stopper are reduced; direct contact with the outside air does not exist, so that the pollution is small.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a disposable split-type aseptic dispensing infusion set. Background technique [0002] The dispensing method to the input liquid in existing medical treatment both at home and abroad, all is to adopt disposable syringe to suck a small amount of liquid to inject in the medicine bottle of dress powder injection, treat that medicine powder dissolves fully and draw back with syringe then inject in the liquid bottle. The above method has the following deficiencies: one, waste of medicine, because the syringe can only extract a small amount of liquid, and the internal space of the powder injection medicine bottle is also very small, and can only inject a little liquid (usually 2-3ml) at a time to dissolve the medicine powder , so high-concentration medicinal liquid also can have more medicinal waste even if there is little residue (0.2-0.3ml) in the medicine bottle and the syringe.

Problems solved by technology

The above method has the following deficiencies: one, waste of medicine, because the syringe can only extract a small amount of liquid, and the internal space of the powder injection medicine bottle is also very small, and can only inject a little liquid (usually 2-3ml) at a time to dissolve the medicine powder , such a high-concentration drug solution will have more drug waste even if there is little residue (0.2-0.3ml) in the drug bottle and syringe

But above-mentioned device has following shortcoming: 1, flexible hose requires higher strength, elasticity etc., can not use common infusion tube, generally uses silica gel to make, and cost is higher, and the structure of all dispensing is all disposable, After dispensing, it will be scrapped and cannot be used in subsequent infusions, resulting in a large waste

2. Although the dispensing process is completed in a closed pipeline, the elastic hose needs a long length, so there is a lot of air inside the elastic hose before it starts dispensing, and it cannot be emptied before use, otherwise it will be difficult To achieve dispensing, the air in the elastic hose will be directly introduced into the dispensing bottle to contact the medicine bottle, which also causes a lot of pollution

3. The performance required by the elastic hose is high, which requires the processing raw materials of the elastic hose to be complicated, and sometimes the liquid medicine will pass through the hose directly when dispensing the medicine, and the raw material components will inevitably enter the liquid medicine when the elastic hose is squeezed , causing pollution

4. The operation is complicated, requiring the liquid medicine bottle or powder bottle to be inverted, and the correct extrusion direction of the elastic hose and the insertion direction of the replacement rod. If the medicine bottle is not inverted, or the inverted medicine bottle is wrong, or the elastic The wrong extrusion direction of the hose and the wrong insertion direction of the replacement rod make it difficult to complete the dispensing process, which is difficult for many ordinary consumers to easily grasp.

5. Without metering function, it is impossible to accurately grasp the amount of medicine prepared during the dispensing process
