Abstract
The utility model provides a liquid washing and purifying air disposable transfusion device which is suitable for the transfusion of the clinical patient, comprising a first stage air filter, a hose, a washing and purifying bottle, a transfusion bottle, a transfusion monitor, a control clamp, a microporous filter and a needle head. The bottom of the washing and purifying bottle is provided with a second stage air filter. The utility model has simple structure and easy use, causes the air in the transfusion device to be clean as the two-stage air filtering and one time liquid washing, and has better effect on purifying the air.
Description
Technical field
This utility model relates to a kind of improved disposable transfusion device that purifies air, and particularly relates to a kind of liquid scrubbing that clinical patient transfusion uses disposable transfusion device that purifies air that is suitable for.
Background technology
Intravenous drip is extensively adopted by medical circle as a kind of important medicinal approaches.The transfusion apparatus repeatedly improves, though taked certain filtration measure in the air cleaning that present widely used disposable transfusion device is entered when balance transfusion bottle negative pressure, but effect still can not satisfy various transfusion place and environment requirement, especially when infected area and open-air rescue, rescuing the critical patient waits the employing intravenous drip the most general, when disposable transfusion device was infused, the air cleaning of carrying out infusion bottle just seemed even more important.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of liquid scrubbing simple in structure, easy to use and the better effects if that purifies air disposable transfusion device that purifies air is provided.
For achieving the above object, the technical scheme that this utility model adopted is: this disposable transfusion device comprises first order air filter 1, flexible pipe 2, washing, purifying bottle 5, infusion bottle 6, dropping monitor 7, control folder 8, microfilter 9 and syringe needle 10, and it is characterized in that: the bottom of described washing, purifying bottle 5 is provided with second level air filter 3.
Be equipped with microporous filter membrane 4 on described first order air filter 1 and the second level air filter 3.
This utility model compared with prior art has the following advantages: this utility model is simple in structure, easy to use, do not need to join in addition cleaning mixture during use, utilize the medicinal liquid in the infusion bottle to get final product, owing to adopted a two-stage air filtration and a liquid scrubbing, make the air that enters in the infusion bottle cleaner, so the better effects if that purifies air.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further.
The disposable transfusion device that purifies air of liquid scrubbing as shown in Figure 1, the washing, purifying bottle 5 that comprises the first order air filter 1 which is provided with microporous filter membrane 4, is connected with first order air filter 1 by flexible pipe 2, the infusion bottle 6 that is connected with washing, purifying bottle 5 by flexible pipe 2, pass through dropping monitor 7 that flexible pipe 2 is connected with infusion bottle 6, the control that is connected with dropping monitor 7 presss from both sides 8, microfilter 9 and syringe needle 10, the bottom of described washing, purifying bottle 5 is provided with the second level air filter 3 of being with microporous filter membrane 4.
During use, washing, purifying bottle 5 is inserted in the infusion bottle 6 for preparing together with dropping monitor 7, finger is controlled the flexible pipe 2 of washing, purifying bottle 5 bottoms and is made it air tight, push the bottle of washing, purifying bottle 5 simultaneously with hands, make in the air admission infusion bottle 6 wherein, decontrol that the liquid in the infusion bottle 6 flows in the washing, purifying bottle 5 behind the hands, it is volumetrical 2/3rds the time when liquid level in the washing, purifying bottle 5 reaches, and the finger of control flexible pipe 2 is removed get final product.Make dropping monitor 7 interior liquid reach at its volumetrical 2/3rds o'clock by the aforesaid operations method and can carry out later routine operation.Because washing, purifying bottle 5 and dropping monitor 7 exist certain height poor, according to siphon principle, liquid in the infusion bottle 6 can only flow in the dropping monitor 7, enter in the infusion bottle 6 after the washing of air liquid in the filtration of first order air filter 1 and second level air filter 3 and washing, purifying bottle 5, simultaneously the liquid in the washing, purifying bottle 5 since entering of air can from washing, purifying bottle 5, not flow out.
Because washing, purifying bottle 5 bottoms are provided with the second level air filter 3 of band microporous filter membrane 4, can reach two kinds of effects like this: 1, the air that enters has been carried out filtering with microporous membrane for the second time; 2, utilize the porous of microporous filter membrane 4, make the air dispersion that enters be the minute bubbles of needle point size, the surface area of increase washing gas makes gas obtain thorough washing.
