Hydro-acupuncture rapid dispensing apparatus

Abstract

The invention relates to a hydro-acupuncture rapid dispensing apparatus, which is characterized by comprising a suction needle which is inserted into a hydro-acupuncture and is used for sucking medicine liquid, a puncture needle which is punctured and inserted in a medicine bottle and is used for conveying the medicine liquid in the hydro-acupuncture into the medicine bottle, and a bearing airbag which is connected to the suction needle and the puncture needle, and is capable of elastically deforming to form negative pressure and simultaneously capable of accommodating the medicine liquid, wherein first check valves are arranged at the connecting ends of the suction needle and the bearing airbag; the opening direction of the first check valves faces the side of the bearing airbag; second check valves are respectively arranged at the connecting ends of the puncture needle and the bearing airbag; and the opening direction of the second check valves is opposite to the side of the bearing airbag. Compared with a conventional dispensing method by virtue of an injector, the dispensing apparatus is simple in operation and capable of effectively avoiding the situations that a needle is repeatedly exposed in air and unclean air in wards is taken into a liquid bottle; and the dispensing apparatus can be used for preventing glass slag and like impurities from entering liquid and can be used for extending to the bottom of a hydro-acupuncture bottle and sucking the medicine liquid relatively thoroughly. The apparatus has the advantages of being simple in structure, controllable in cost, disposable, sterile and safe, capable of improving dispensing efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a rapid water needle dispensing device. Background technique [0002] At present, the dispensing referred to in medical treatment usually refers to transferring medicinal liquid or medicinal powder into a liquid bottle and injecting it into the human body for treatment through infusion. Existing domestic and foreign methods of dispensing water injections usually use a grinding wheel to cut the neck of a small glass ampoule, then break off the upper part or directly crush the upper part with a metal instrument (such as scissors, tweezers, etc.), and then use a syringe to suck it. The liquid medicine is injected into the liquid bottle. The disadvantages of the above-mentioned liquid preparation method are: the capacity of the syringe is limited, if a group of liquids needs to be prepared with multiple water injection ampoules, it is necessary to extract and repeatedly punc...

AI Technical Summary

Problems solved by technology

The disadvantages of the above-mentioned liquid preparation method are: the capacity of the syringe is limited, if a group of liquids needs to be equipped with a plurality of water injection ampoules of medicinal liquid, it is necessary to extract and repeatedly puncture the rubber stopper of the liquid bottle, which is cumbersome to operate and increases Chances of iatrogenic contamination

In addition, the syringe has no filtering function, and the suction process may inhale unclean air in the ward to cause liquid pollution

At the same time, when the ampoule of water injection is broken, glass shards will inevitably be produced. If a syringe is used to dispense the liquid, the tiny glass shards may be sucked into the liquid bottle, and then injected into the blood vessel to form a glass embolism, which will cause harm to the human body.
