Abstract

The utility model relates to a transfusion apparatus, comprising transfusion modules and ventilating modules, wherein the transfusion modules comprise a first upper pinhead, a first Murphy dropper, a liquid medicine adjuster and an injecting and puncturing needle which are sequentially connected by a transfusion tube. The ventilating modules comprise a filtrating net and a ventilating tube, the structure is characterized in that the ventilating modules further comprise a second Murphy dropper, moreover, the filtrating net, the second Murphy dropper and the ventilating tube are sequentially in series connected. The ventilating modules and the transfusion modules are integrated or separated. When the ventilating modules and the transfusion modules are integrated, the ventilating modules are connected in parallel with the air intake hole of a first upper pinhead. When the ventilating modules and the transfusion modules are separated, the upper end of the ventilating tube is in series connected with a second upper pinhead. When the transfusion apparatus is used, the liquid medicine cannot be polluted by the air entering into the intracavity of the transfusion bottle, thereby ensuring the safety and sanitation in the transfusion process.

Description

A kind of transfusion device

Technical field

This utility model relates to a kind of transfusion apparatus, a kind of transfusion device of more specifically saying so.

Background technology

Traditional transfusion device comprises last syringe needle, Murphy's burette, medicinal liquid flow actuator, the injection puncture needle that is connected in series successively with tube for transfusion, is parallel with the breather that the end has drainage screen on that section tube for transfusion between last syringe needle and the Murphy's burette.This traditional transfusion device, in process to patient's transfusion, extraneous air passes through filter screen successively, breather, that section tube for transfusion that is connected with last syringe needle, last syringe needle, medicinal liquid in the transfusion bottle enters the inner chamber of transfusion bottle, owing to can not the air that enter the transfusion bottle inner chamber be purified, sterilization, therefore aerial fine dust floats, pathogenic bacteria and virus, at that section tube for transfusion through being connected with last syringe needle, last syringe needle, during the stretch of the medicinal liquid in transfusion bottle footpath, can produce this section path and pollute, and then pollution medicinal liquid, contaminated medicinal liquid passes through tube for transfusion, the injection puncture needle enters in the human body, and human body is worked the mischief.

Summary of the invention

The purpose of this utility model provides the transfusion device that a kind of air that enters the transfusion bottle inner chamber can not pollute medicinal liquid.

In order to realize above-mentioned purpose, the transfusion device that is provided, comprise infusion set and ventilation assembly, infusion set include with tube for transfusion be connected in series successively first on syringe needle, first Murphy's burette, the medicinal liquid flow actuator, the injection puncture needle, the ventilation assembly includes drainage screen, breather, its construction features is that the ventilation assembly also includes second Murphy's burette, drainage screen, second Murphy's burette, breather is serially connected successively, ventilation assembly and infusion set is connected as a single entity or split, when ventilate assembly and infusion set are connected as a single entity, the ventilation assembly is connected in parallel on the air inlet of syringe needle on first, when ventilate assembly and infusion set are split, be serially connected with syringe needle on second in the upper end of breather.

Above-mentioned drainage screen is filter paper or sponge.

Transfusion device provided by the utility model, when infusing to the patient, the first medicinal liquid identical of in second Murphy's burette, packing into transfusion bottle, the charge weight of medicinal liquid is the volumetrical 1/4-1/3 of second Murphy's burette, undertaken by following operating procedure: 1, when ventilate assembly and infusion set were connected as a single entity, transfusion operation rules were routinely infused to the patient again; 2, when ventilate assembly and infusion set are split, the assembly of will ventilating is inserted in the transfusion bottle by syringe needle on second, infusion set respectively by syringe needle on first, and the needle point of syringe needle on second is positioned on the medicinal liquid liquid level, the needle point of syringe needle is positioned among the medicinal liquid on first, transfusion operation rules are routinely infused to the patient again.

Transfusion device provided by the utility model, owing to be serially connected with second Murphy's burette that medicinal liquid is housed in the ventilation assembly, extraneous air, earlier by the bigger dust of drainage screen filtering granule, by being enclosed in the small dust of medicinal liquid filtering granule in second Murphy's burette and pathogenic bacteria virus being killed sterilization, enter into again in the transfusion bottle again, so, the air that enters in the transfusion bottle has been carried out purification, sterilization, can not pollute, guaranteed the safety and sanitation of infusion process medicinal liquid.

Learn by above narration, transfusion device provided by the utility model, when infusing to the patient, the air that enters the transfusion bottle inner chamber can not pollute medicinal liquid, has guaranteed the safety and sanitation of infusion process.

Description of drawings

Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings, wherein:

Fig. 1 is the structural representation of described ventilation assembly of embodiment and infusion set transfusion device when being connected as a single entity;

Fig. 2 is the structural representation of described ventilation assembly of embodiment and infusion set transfusion device when being split;

Among the figure: 1 is syringe needle on first, and 2 is first Murphy's burette, and 3 is tube for transfusion, and 4 is the medicinal liquid flow actuator, and 5 are the injection puncture needle, and 6 is breather, and 7 is second Murphy's burette, and 8 is drainage screen, and 9 is medicinal liquid, and 10 is transfusion bottle, and 11 is syringe needle on second.

The specific embodiment

With reference to accompanying drawing, the described transfusion device of embodiment, comprise infusion set and ventilation assembly, infusion set include with tube for transfusion 3 be connected in series successively first on syringe needle 1, first Murphy's burette 2, medicinal liquid flow actuator 4, injection puncture needle 5, the ventilation assembly includes the drainage screen 8 that is serially connected successively, second Murphy's burette 7, breather 6, drainage screen 8 is filter paper or sponge, ventilation assembly and infusion set is connected as a single entity or split, when ventilate assembly and infusion set are connected as a single entity, the ventilation assembly is connected in parallel on the air inlet of syringe needle 1 on first, when ventilate assembly and infusion set are split, be serially connected with syringe needle 11 on second in the upper end of breather 6, when infusing to the patient, the needle point of syringe needle 11 is positioned on medicinal liquid 9 liquid levels on second, the needle point of syringe needle 1 is positioned among the medicinal liquid 9 on first, and the charge weight of medicinal liquid 9 in second Murphy's burette 7 is controlled at second Murphy's burette, 7 volumetrical 1/4-1/3.

In the present embodiment,, belong to known technology, do not draw in detail among the figure, literal no longer carefully states because first Murphy's burette 2, second Murphy's burette 7, medicinal liquid flow actuator 4, drainage screen 8 are products of public offering on the market.
