Abstract
The utility model relates to a disposable transfusion device which is characterized in that an anti-backflow mechanism composed of an anti-flow tube (7) and an elastic rubber tube (8) with a stitching port is arranged in an air intake conduit (1). A flow regulator (5) of the anti-backflow mechanism adopts a thread type regulating structure. In use, the utility model has convenient and reliable operation, effectively prevents physic liquor from back flowing, and prevents the physic liquor form being polluted by air, and the dropping speed is easy to control and regulate.
Description
This utility model relates to a kind of medical apparatus and instruments, exactly is disposable antireflux screw regulating type transfusion device.Existing disposable transfusion device in use, on the one hand when the air induction conduit distal openings is lower than in the infusion bottle liquid plane and annotates medicinal liquid in infusion bottle, liquid easily flows out from air induction conduit, the liquid that refluxes has increased the probability that the bottle inner liquid medicine pollutes, on the other hand, a speed of the wayward dropping liquid of roller type flow regulator.
The purpose of this utility model is: provide a kind of and prevent that liquid flows out, is easy to adjust the disposable transfusion device that drips speed from air induction conduit in the infusion bottle.
The technical solution that realizes above-mentioned purpose is such.
Disposable antireflux adjustable type transfusion device is made up of air induction conduit (1), bottle plug puncture unit (2), dropper (3), flow regulator (5), filter (12) and intravenous needle (6), it is characterized in that:
Plug an antireflux pipe (7) in the far-end of a, described air induction conduit (1), the inner extending end of antireflux pipe (7) is provided with the elastic rubber tube (8) of end sealing, the tube wall of elastic rubber tube (8) is provided with the sealing (9) of one or more, and the overhanging end of control valve (7) is provided with filter membrane;
B, described flow regulator (5) are screw regulating type, on the tube for transfusion (4) between dropper (3) and the filter (12), establish a tee T (10), be provided with female thread in the overhanging port of tee T (10), one bolt (11) is located in the tee T (10) with screw-internal thread fit, and the end of bolt (11) is that a thin straight-bar matches with tee T (10) internal diameter.
This utility model has prevented that effectively medicinal liquid from flowing out from air inlet pipe owing to adopted the antireflux pipe and had the elastic rubber tube of sealing, reduced liquid medicine contamination probability, adopted the screw-type flow regulator, make the speed of dripping of transfusion be easy to control.
Fig. 1 is this utility model structural representation.
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
As seen from Figure 1, this disposable transfusion device is made up of air induction conduit (1), bottle plug puncture unit (2), dropper (3), flow regulator (5) and intravenous needle (6).
In the pipe end of air induction conduit (1), plug an antireflux pipe (7), suit the elastic rubber tube (8) of end sealing on the inner extending end of antireflux pipe (7), have a sealing (9) on the Guan Bi of elastic rubber tube (8), sealing is scratched on elastic rubber tube (8) sidewall with cutter, on the overhanging end of control valve (7) filter membrane is housed.
This utility model adopts the screw-type flow regulator, on the tube for transfusion (4) between dropper (3) and the filter (12), be connected a tee T (10), the pipe end of tee T (10) is that corrugated tubing cooperates with bolt (11), and the boom end of bolt (11) is that thin straight-bar matches with the internal diameter of tee T (10).
In the use, during transfusion under the pressure differential effect inside and outside the infusion bottle.Air enters control valve (7) through filter membrane, washes sealing (9) open through elastic rubber tube (8) again and enters air inlet pipe (1).Transfusion closes on end, and infusion bottle external and internal pressure difference reduces gradually; When pressure differential was decreased to the sealing (9) that can not wash open on the elastic rubber tube (8), air can not enter air induction conduit (1), and transfusion stops.
The screw-type flow regulator in use.Outwards rotating bolt (11) drives thin straight-bar and moves outward, and communication port is increased, and drips speed and accelerates, and inwardly rotating bolt (11) drives in the thin straight-bar and stretches, and can reduce and drip speed.
Claims (1)
1, disposable antireflux screw regulating type transfusion device is made up of air induction conduit (1), bottle plug puncture unit (2) dropper (3), flow regulator (5), filter (12) and intravenous needle (6), it is characterized in that:
