Description
Technical field
This utility model relates to a kind of medical Transfusion device, particularly relates to a kind of easy for looking back flow of blood, prevents the disposable safe transfusion system of blood back.
Background technology
The disposable medical transfusion device is one of medical apparatus commonly used at present.When intravenous injection, dropper is injected again, with full of liquid in the pipeline of injection needle because injection needle directly connects tube for transfusion, and caliber is than full of liquid again in the tubule, and during venipuncture, the blood back amount is few, difficulty is seen the blood backflow phenomenon, be difficult to determine whether syringe needle enters vein, processing method commonly used is the extruding tube for transfusion, discharge section liquid, produce negative pressure and then observe blood back, careless slightly, injection needle puncture vein surrounding tissue easily causes the part to be swollen with.In addition, the duty of infusion process is that medicinal liquid bottle or medicinal fluid bag are wanted high extension, by the potential difference transfusion, the transfusion performance is relevant with the height that medicinal liquid bottle pavilion is hung, therefore, unstable properties, the position not to the time easily cause blood to reflux, the common method that addresses this problem is to utilize the ball float of ball-type or pyramid type shape, prevents that medicinal liquid from all flowing out.Also have owing to dosing in the infusion process and other reason, be mingled with bubble through regular meeting in the medicinal liquid,, will cause trouble even danger to the patient if bubble enters in patient's body.Therefore medical personnel will in time discharge the bubble in the medicinal liquid, and the existence of present liquid medicine filter is not easy to carry out aforesaid operations or the difficult defective of operation.
Summary of the invention
The purpose of this utility model is to remedy the deficiencies in the prior art, a kind of easy for looking back flow of blood is provided, prevents blood back, can in time discharges the disposable safe transfusion system of gas in the conduit.
The purpose of this utility model is achieved through the following technical solutions.
Disposable safe transfusion system of the present utility model, it connects successively with conduit wears a bottle pin, dropping funnel, fluid flow regulator, liquid medicine filter, infusion needle and constitutes, the described bottle pin of wearing is provided with air filter, wherein, be connected with anti-adverse current backstop between described liquid medicine filter and the infusion needle, described anti-adverse current backstop is provided with filter membrane and exhaust valve.
The top of described anti-adverse current backstop is provided with adapter, and the below is provided with lower connector, and the described adapter below of going up is with anti-adverse current non-return symphysis joint, and anti-adverse current non-return symphysis joint below is provided with anti-adverse current non-return film.
The beneficial effects of the utility model are: an end of anti-adverse current non-return film is connected with conduit by anti-adverse current non-return symphysis joint and last adapter, the other end is a thin plastic, and medicinal liquid can only flow from top to bottom under the effect of anti-adverse current non-return film pressure at both sides, can not be toward the upper reaches, thus, prevent blood back.When in the conduit air being arranged, open exhaust valve, air-out prevents that bubble from entering in the body.In addition, under the effect of described filter membrane, a discharged air, medicinal liquid can not flow out.That this utility model also has is simple in structure, easy to operate, cost is low, time saving and energy saving, easy for looking back flow of blood, prevent blood back, timely advantage such as air-out.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the generalized section of anti-adverse current backstop of the present utility model.
Fig. 3 is that the A of Fig. 2 is to view.
Among the figure, 1, wear bottle pin 2, air filter 3, dropping funnel 4, conduit 5, fluid flow regulator 6, liquid medicine filter 7, filter membrane 8, exhaust valve 9, anti-adverse current backstop 10, infusion needle 11, go up adapter 12, anti-adverse current non-return symphysis joint 13, anti-adverse current non-return film 14, lower connector
The specific embodiment
As shown in Figure 1, disposable safe transfusion system of the present utility model, it connects successively with conduit 4 wears bottle pin 1, dropping funnel 3, fluid flow regulator 5, liquid medicine filter 6, infusion needle 10 and constituting, the described bottle pin 1 of wearing is provided with air filter 2, wherein, be connected with anti-adverse current backstop 9 between described liquid medicine filter 6 and the infusion needle 10, described anti-adverse current backstop 9 plays the blood back cushioning effect when acupuncture treatment, promptly, suitably press with hands, just produce negative pressure, reach and see the blood purpose, described anti-adverse current backstop 9 is provided with filter membrane 7 and exhaust valve 8, open the air in described exhaust valve 8 discharge tubes, medicinal liquid flows to lower connector 14 by anti-adverse current non-return film 13, and under the effect of anti-adverse current non-return film, medicinal liquid can not reflux, in addition, under the effect of the filter membrane 7 that is provided with on the anti-adverse current backstop 9, can only discharged air by exhaust valve 8, can not flow out medicinal liquid.
As shown in Figure 2, disposable safe transfusion system of the present utility model, the top of described anti-adverse current backstop 9 is provided with adapter 11, last adapter 11 and liquid medicine filter 6 interconnect by conduit, the below of described anti-adverse current backstop 9 is provided with lower connector 14, lower connector 14 and infusion needle 10 interconnect by conduit, and described below of going up adapter 11 is with anti-adverse current non-return symphysis joint 12, and anti-adverse current non-return symphysis joint 12 is provided with anti-adverse current non-return film 13.
As shown in Figure 3, an end of anti-adverse current non-return film 13 is connected with conduit by anti-adverse current non-return symphysis joint 12 and last adapter 11, and the other end is a thin plastic, medicinal liquid can only flow from top to bottom under the effect of anti-adverse current non-return film 13 pressure at both sides, can not thus, prevent blood back toward the upper reaches.
During concrete enforcement, open the exhaust valve 8 on the anti-adverse current backstop 9 earlier, this moment injection needle 10 conduit in be full of medicinal liquid, close flow regulator 5 blocking-up liquid stream then after, inject.If injection needle has entered vein, just can see the blood back phenomenon, if injection needle does not enter vein, that is, do not see that the blood back phenomenon then continues puncture to syringe needle along the vein direction, up to blood back occurring.After syringe needle enters vein, just close exhaust valve 8, at this moment medicinal liquid can only be toward dirty under the effect of anti-adverse current non-return film 13, can not blood back, as long as the height of anti-adverse current backstop 9 is no more than the patient body height, the medicinal liquid in the anti-adverse current backstop 9 just can not enter in the human body.When in the conduit air being arranged, open exhaust valve 8 discharged air, after having arranged air, again exhaust valve 8 cuts out, carry out normal infusion.
