Abstract
The utility model relates to an air pollution prevention disposable transfusion device which is composed of a thin and long tube (1), a needle head (2), a telescopic hose (3) and an air filter screen (5). The utility model is characterized in that the telescopic hose is sheathed on the end of the needle head (2), and the thin and long tube (1) is inserted and connected with the needle head (2) and the telescopic hose (3). One end head of the thin and long tube (1) is fixed to the air filter screen (5), and the side of the other end head of the thin and long tube (1) is provided with an air hole (6). The utility model has the advantages of simple structure, convenient operation and low cost, and is an air pollution prevention disposable transfusion filter which can keep physic liquor clean.
Description
This utility model relates to a kind of anti-air pollution disposable transfusion device, relates to specifically a kind ofly can keep the medicinal liquid cleaning, prevents the disposable infusion filter of air pollution medicinal liquid.
At present, its structural principle of transfusion device that uses clinically in hospital, clinic etc. is to utilize liquid severe poor, makes the infusion bottle internal air pressure be lower than external atmosphere pressure (for negative pressure), and the air hose that is inserted in the infusion bottle bottom utilizes negative pressure that air is sucked in the infusion bottle.It is insufficient to be: in the process in the air admission bottle, the air minute bubbles rise to top in the infusion bottle by the medicinal liquid in the infusion bottle, in the process that minute bubbles rise, air in the minute bubbles is about to import human body in the infusion bottle medicinal liquid filters, air has been filtered like this, promptly purified air, however minute bubbles in air but polluted the medicinal liquid that is about to import human body, as everyone knows this be one can't be by the fact that the patient accepted.So the structure of existing transfusion device structure needs further improvement.
The purpose of this utility model just is to design a kind of anti-air pollution disposable transfusion device that can keep the medicinal liquid cleaning, to overcome the deficiencies in the prior art.
Order of the present utility model is achieved in that it is made up of elongated tubular (1), syringe needle (2), bellows (3), air filter screen (5), it is characterized in that: be set with bellows (3) on the termination of syringe needle (2), be plugged with elongated tubular (1) in syringe needle (2) and the bellows (3), one termination of elongated tubular (1) is connected with air filter screen (5), and the side of another termination of elongated tubular (1) is provided with pore (6).
Its feature also is: syringe needle (2) is provided with handrail ring (7), and bellows (3) is provided with steam vent (4).
This utility model is compared with prior art: it is simple in structure, operates simple and easyly, with low cost, is a kind of disposable filter for transfusion of using of anti-air-polluting that can keep the medicinal liquid cleaning.
Below in conjunction with drawings and Examples this utility model is further specified:
Accompanying drawing is that this utility model overall structure master looks sketch map.
Wherein: 1, elongated tubular, 2, syringe needle, 3, bellows, 4, steam vent, 5, air filter screen, 6, pore, 7, the handrail ring.
Embodiment: it is made up of this utility model elongated tubular 1, syringe needle 2, bellows 3, air filter screen 5, described syringe needle 2, present embodiment is selected thicker syringe needle 2 for use, and syringe needle 2 is provided with handrail ring 7, be set with bellows 3 on the termination of syringe needle 2, bellows 3 is provided with steam vent 4.Be plugged with elongated tubular 1 in syringe needle 2 and the bellows 3, a termination of elongated tubular 1 is connected with air filter screen 5, and the side of elongated tubular 1 another termination is provided with the pore 6 that can ventilate.During use, syringe needle 2 is inserted in the rubber lid of infusion bottles, hand push bellows 3 makes and carries on the elongated tubular 1 that is plugged with in syringe needle 2 and the bellows 3 that elongated tubular 1 passes the syringe needle mouth and exposes liquid level.At this moment, the air in the bellows 3 is discharged from steam vent 4.During transfusion, air filters by air filter screen 5, on the liquid level in elongated tubular 1 directly enters bottle, has avoided the pollution of air to medicinal liquid again.
Claims (2)
1, a kind of anti-air pollution disposable transfusion device, it is made up of elongated tubular (1), syringe needle (2), bellows (3), air filter screen (5), it is characterized in that: be set with bellows (3) on the termination of syringe needle (2), be plugged with elongated tubular (1) in syringe needle (2) and the bellows (3), one termination of elongated tubular (1) is connected with air filter screen (5), and the side of another termination of elongated tubular (1) is provided with pore (6).
