Hard dual port

Abstract

The invention discloses a hard dual port belonging to the technical field of medical mechanism manufacture technology. The hard dual port is convenient to use and operate and can effectively prevent the generation of the secondary pollution when being used. The hard dual port comprises a hard dual port body comprising a medicine mixing channel, wherein the hard dual port body is provided with an inner side surface and an outer side surface; an input port of the medicine mixing channel is placed on the inner side surface of the hard dual port body, and an output port of the medicine mixing channel is placed on the outer side surface of the hard dual port body, and protrudes the outside face; and the hard dual port further comprises an easily-folded handle with a flow guiding groove; and the easily-folded handle is axially arranged at the tail end of the output port of the medicine mixing channel along the medicine mixing channel; and the tail end of the output port is sealed.

Description

technical field [0001] The invention relates to a hard dual interface, which belongs to the technical field of medical equipment 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 pollution of the drug solution. [0003] The patent N...

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 adhesive is bonded to the open end 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, and at the same time, the adhesive itself will also cause mixing. Pollution of 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 easy-to-break handle is easily dropped into the infusion bag after being broken, or is easy to puncture the infusion bag when it is broken, in the prior art, according to the structural characteristics of the mixing mouth and the hard double interface connected by the sealing rubber tube, there are also The easy-break handle is set 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 it is not broken. The easy-to-break handle opens the mixing channel, and the easy-to-break handle will always be immersed in the liquid, increasing the risk of secondary pollution
