Abstract
The utility model discloses a disposable vein liquid-injecting filter-type scalp needle comprises a needle 1, a scalp needle hose 2, and a needle stand 3, wherein a self-blocking style filter 4 is arranged on the scalp needle hose 2, and the outer end of the self-blocking style filter 4 is connected to a vein liquid-injecting needle stand 5. The utility model has the advantages of simple structure, convenient operation, and extensive vein liquid-injecting application.
Description
This utility model relates to a kind of the transfusion with the improvement of scalp acupuncture, and specifically a kind of disposable vein is injected liquid filtering type scalp acupuncture.
In clinical treatment rescue process, except that vein input medicinal liquid, the intravenous injection medicinal liquid also is one of important means of rescuing.When vein input medicinal liquid or intravenous injection medicinal liquid, all need use scalp acupuncture.At present; the scalp acupuncture that uses is made of syringe needle, scalp acupuncture flexible pipe, needle stand; in infusion process; as need intravenous injection medicinal liquid, then need pull up tube for transfusion, in needle stand, push the first aid medicinal liquid; the shortcoming of this scalp acupuncture is: in pushing the whole process of medicinal liquid; unavoidable medicinal liquid is contaminated, often has many infection microgranules or glass granules etc. to enter in the human body, causes unnecessary damages to the patient.For overcoming above shortcoming, what have has added defecator on the scalp acupuncture flexible pipe, though certain filtration is arranged in injecting the medicine process, but the contaminate particulate in the medicinal liquid rests on the drainage screen, in continuing infusion process, contaminate particulate constantly washes away down medicinal liquid, still has many microgranules to pass drainage screen gradually and enters human body, bring the problem of injury to fail to be solved to the patient at all, but also the normal transfusion of influence.Simultaneously, because needle stand separates with tube for transfusion, connector is exposed among the air, also causes certain pollution easily.
The purpose of this utility model is to provide a kind of can effectively filter particulates emission in the intravenous injection medicinal liquid, has avoided needle stand to separate the pollution that causes with transfusion again simultaneously, is disposable vein injection liquid filtering type scalp acupuncture simple to operate, easy to use.
This utility model is achieved in that this disposable vein injects liquid filtering type scalp acupuncture, constitute by syringe needle, scalp acupuncture flexible pipe and needle stand, set up the self-block filter on the scalp acupuncture flexible pipe separately, self-block filter outer termination intravenous injection liquid needle stand also is provided with stopper on intravenous injection liquid needle stand.This disposable vein is injected liquid filtering type scalp acupuncture and also implemented by following measure: the self-block filter is made of housing, drainage screen, stifled certainly rubber membrane, and drainage screen is fixed in the housing, fixing going up from stifled rubber membrane on the inwall of the outside housing of drainage screen; The self-block rubber membrane is a thin film, and a hemisphere plush copper is established in the centre, and the hemisphere plush copper gets lodged on the pipe internal orifice of intravenous injection liquid needle stand, is provided with the liquid input hole on every side.When injection liquid, unstop, with syringe injection liquid in intravenous injection liquid needle stand, from stifled rubber membrane under the medicinal liquid thrust, leave the pipe internal orifice of intravenous injection liquid needle stand from the hemisphere plush copper of stifled rubber membrane, medicinal liquid passes drainage screen through the liquid input hole on stifled rubber membrane, enters scalp acupuncture flexible pipe, syringe needle then successively, enters human body at last.Injected medicinal liquid, begun to continue transfusion, input liquid enters housing, from inside to outside promote from stifled rubber membrane, make from stifled rubber membrane hemisphere plush copper and block on the pipe internal orifice of intravenous injection liquid needle stand, reflux to prevent medicinal liquid, last again with the stopper plug on the pipe collar extension of intravenous injection liquid needle stand.
Advantage of the present utility model is: simple in structure, easy to operate, when more effectively preventing the intravenous injection medicinal liquid harmful substance to the injury of human body.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 looks sketch map for this utility model master.
Fig. 2 analyses and observe enlarged diagram for this utility model self-block filter along axis.
Fig. 3 is that this utility model is from stifled rubber membrane schematic top plan view.
Make this utility model with reference to accompanying drawing 1,2,3.This disposable vein is injected liquid filtering type scalp acupuncture, is made of syringe needle 1, scalp acupuncture flexible pipe 2 and needle stand 3, sets up self-block filter 4 on scalp acupuncture flexible pipe 2 separately, the outer termination intravenous injection liquid needle stand 5 of self-block filter 4; Self-block filter 4 is made of housing 10, drainage screen 6 and stifled certainly rubber membrane 7, and drainage screen 6 is fixed in the housing 10, fixing going up from stifled rubber membrane 7 on the inwall of the outside housing 10 of drainage screen 6; From stifled rubber membrane 7 is a thin film, and a hemisphere plush copper 8 is established in the centre, and hemisphere plush copper 8 gets lodged on the pipe internal orifice of intravenous injection liquid needle stand 5, is provided with liquid input hole 9 on every side, also establishes shutoff stopper 11 on needle stand 5.
