Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of intravenous transfusion device for anti-return blood.
Background technology
In clinical position, medical personnel are by the cone joint partial insertion infusion bottle of transfusion device, and infusion bottle is hung on transfusion pole, and aerofluxus also makes whole liquid-transport pipe-line be full of medicinal liquid, fasten actuator, then row vein punctures, and fixing puncture needle also adjusts a speed.Under atmospheric pressure effect, during in bottle, liquid runs down infusion tube flows into Murphy's dropper, when in Murphy's dropper, water column pressure is more than venous pressure, the liquid runs down tube for transfusion in bottle flows into vein.But medicinal liquid is totally lost or in tube for transfusion during remaining a small amount of medicinal liquid, water column pressure is less than venous pressure, if closing flow regulator the most in time or extracting intravenous needle, then may result in venous patient blood to be back in liquid-transport pipe-line, though not entail dangers to patients ' lives, but not understanding of patient can be caused, and be likely to cause doctor-patient dispute.
Summary of the invention
The purpose of this utility model is to provide a kind of intravenous transfusion device for anti-return blood, when solving transfusion present in prior art, defeated admitting air into and the problem of blood back occurs.
This utility model be employed technical scheme comprise that, a kind of intravenous transfusion device for anti-return blood, including infusion tube body, one end of infusion tube body is provided with infusion bottle and connects end, the other end of infusion tube body is provided with intravenous needle and connects end, from infusion bottle connects end, infusion tube body is disposed with Murphy's dropper, flow regulator and one-way flow parts, ball float it is provided with in Murphy's dropper, on Murphy's dropper and connecting end near infusion bottle and be provided with exhaustor, the diameter of ball float is more than the internal diameter of described infusion tube body；The internal diameter of exhaustor is not less than the diameter of described ball float.
Further, one-way flow parts are bag-shaped valve group, bag-shaped valve group includes the first bag-shaped valve and the second bag-shaped valve, first bag-shaped valve and the second bag-shaped valve are with the symmetrical setting of axis of infusion tube body, and the opening of the first bag-shaped valve and the opening of the second bag-shaped valve all connect end towards intravenous needle.
Further, the opening of bag-shaped valve group distance that position is connected between end with described intravenous needle is set less than or equal to infusion tube body length
1/20
。
Further, the material of bag-shaped valve group is low-density polyethylene film.
Further, exhaustor is provided with lid.
The beneficial effects of the utility model are: be provided with in this utility model Murphy's dropper enter from exhaustor, ball float that weight is suitable, this ball float can float the connector opening Murphy's dropper with infusion tube body after liquid entrance is a certain amount of, this connector can be shut again after liquid reduces, there is soft elastic force plastic material ball sealer, prevent defeated admitting air into, cause adverse consequences.This utility model is by arranging valve the most internal, when normal infusion, valve is attached at infusion tube body internal surface, when vein blood back, bag-shaped valve is full to be expanded, and two valve outer surface laminatings form Guan Bi, neither affect transfusion, there is again preferable anti-blood to be back to transfusion device effect, reduce the injury to patient and doctor-patient dispute.This utility model for people provide a kind of simple for production easy, with low cost, sealing effect is good, can for people see a doctor transfusion provide a kind of safe, light, inexpensive new relieved Transfusion needle pipe of disposable safe.
