A kind of anti-pollution transfusion soft bag

Abstract

The invention discloses a transfusion soft bag, in particular discloses an anti-pollution transfusion soft bag, which belongs to the technical field of medical device manufacturing. An anti-pollution transfusion soft bag that is not easily polluted during storage, transportation and use is provided. The soft infusion bag includes a soft infusion bag body, a hard double interface, a drug mixing nozzle and an easy-to-break handle; the drug mixing nozzle is composed of a drug mixing card body and a syringe body, and the drug mixing card body has an open end and a closed end. The syringe body is located at the closed end; the hard double interface includes a base body and a drug mixing channel arranged on the base body; the hard double interface is connected to the infusion soft bag body through the base body, and is installed on the drug mixing channel outside the infusion bag body and the syringe body The sealing rubber tube and the mixing nozzle are connected as a whole, and it also includes a closed end cover, which is detachably installed on the open end of the mixing card body, and seals the open end, and the easy-folding handle is set in the sealing rubber tube. The end of the drug mixing channel of the hard double interface, and the end of the drug mixing channel is closed.

Description

technical field [0001] The invention relates to a transfusion soft bag, in particular to an anti-pollution transfusion soft bag, which belongs to the technical field of medical device manufacturing. Background technique [0002] When using the powder injection, freeze-dried powder injection or water injection contained in the vial, it is necessary to draw out the liquid medicine or water for injection in the infusion soft bag and inject it into the vial through the syringe, and repeat the above work until there is enough liquid medicine in the vial Then the vial is shaken repeatedly until the medicament in the bottle is evenly mixed, and then the medicinal liquid in the vial is extracted and injected into the soft infusion bag with a syringe, and so on, until the medicinal liquid in the bottle is exhausted. The above-mentioned drug mixing operation process is time-consuming, laborious, and consumes consumable materials such as syringes, and it is very easy to cause secondary...

AI Technical Summary

Problems solved by technology

But this medicine mixing interface also has many deficiencies, and its weak point mainly contains the following points: 1, the frangible handle of described mixing medicine interface is positioned at infusion soft bag, when using, after breaking the frangible handle, the frangible handle The section is very easy to fall into the soft infusion bag. At the same time, when the frangible handle is broken, plastic particles will be produced to pollute the drug solution in the infusion soft bag. The breaking force is relatively large, and it is very easy to puncture the soft infusion bag during the breaking operation, making the soft infusion bag unusable; 2. The sealing of the mixed drug card body that fixes the vial is to paste the support plate on the protective film, and then through bonding The drug protective film is bonded to the open end face of the mixed drug card body, so that the protective film is easy to fall off during storage and transportation, causing contamination of the syringe body in the mixed drug card body. At the same time, the adhesive itself It will also cause contamination of the mixed drug card body

And because the syringe body of this technology is made of polypropylene material, it is difficult to achieve the effect of smoothly piercing the vial cap in the actual use process, and the syringe body and the mixing nozzle are assembled structures, which are difficult to obtain during transportation or use. easy to loosen or drop, causing leakage and contamination

In addition, the connection base of the mixing drug interface is designed as a boat-shaped structure with a smooth surface and sharp water chestnuts at both ends of the base. Such a structure uses a high welding temperature during the welding process with the infusion soft bag, which is likely to cause The "over-welding" of the soft bag seriously affects the sealing performance and causes liquid leakage, and the sharp edges and corners are very easy to damage the infusion soft bag itself during the storage and transportation of the drug, and it is also easy to cause leakage and waste of raw materials

[0004] In order to overcome the problem that the above-mentioned frangible handle is easy to fall into the infusion bag after being broken, or it is easy to puncture the soft infusion bag when it is broken, in the prior art, according to the structural characteristics of the connection between the mixing mouth and the hard double interface through the sealing rubber tube, there are The improved structure of setting the easy-break handle at the end of the syringe body in the sealing rubber tube, the main disadvantage of this structure is that during use, the easy-break handle is located at the lower part of the infusion soft bag, so that the liquid will enter the mixing channel, even if The easy-to-break handle is not broken to open the mixing channel, and the easy-to-break handle will always be soaked in liquid, increasing the risk of secondary pollution
