Abstract

The utility model discloses a connecting tube of a reverse-flow-preventing infusion apparatus. The connecting tube comprises a hard connecting tube body with two ends connected with an infusion hose respectively, a medicine filling hole is formed in the hard connecting tube body, and a flexible sealing plug is arranged at the position of the medicine filling hole in a sealing mode. The hard connecting tube body located at the lower portion of the medicine filling hole is provided with a reverse-flow-preventing cavity, a plugging block with a conical structure is arranged in the reverse-flow-preventing cavity, and supporting salient points are arranged at the edge position of the bottom concave surface of the plugging block. The hard connecting tube body located at the lower portion of the medicine filling hole is provided with a filter cavity, and a filter screen is arranged in the filter cavity. The outer wall of the hard connecting tube body close to the position of the medicine filling hole is a rough surface. The connecting tube of the reverse-flow-preventing infusion apparatus has the advantages that the connecting tube is simple in structure, so that harm of local retained air to a patient is avoided; meanwhile the reverse-flow-preventing effect is good, the blood of the patient does not flow back to the infusion connecting tube, the filter screen in the filter cavity can prevent the air and other insoluble particles from entering the blood of the patient, and the rough surface close to the position of the medicine filling hole facilitates taking of the infusion connecting tube during infusion.

Description

Counnter attack streaming transfusion utensil connecting pipe
Technical field
This utility model relates to intravenous transfusion device, especially relates to a kind of counnter attack streaming transfusion utensil connecting pipe.
Background technology
Transfusion device is a kind of disposable medical consumptive material for venous transfusion, mainly by transfusion needle, transfusion utensil connecting pipe, infusion tube, flow regulator, black Maufee type tube, liquid medicine filter and bottle plug puncture unit, air inlet pipe air filter etc., is connected to form.When transfusion utensil connecting pipe is used, lower end is connected with infusion needle by infusion tube, and upper end is connected with flow regulator by infusion tube, adds for convenience other drug, and on connection tube, bypass has injection arm.The connection tube of this Y-shaped structure is when transfusion, and injection arm place usually retains a small amount of air, and when through injection herein, air can inject in tube for transfusion inflow patient body, causes the serious consequences such as air embolism; If transfusion simultaneously finishes not close transfusion device in time, also there will be blood reflux stream, the blood storage of anti-stream is stayed medicine-pouring pipe place and can be formed blood clot.For preventing blood reflux stream, existing backflow-proof transfusion device has increased globe valve between transfusion needle and tube for transfusion, if but anti-flow is difficult to promote globe valve when less and tube wall fits tightly, and antireflux effect is not good enough.
Summary of the invention
The purpose of this utility model is to provide a kind of transfusion utensil connecting pipe of being not only convenient to safe injection but also can having avoided blood reflux stream.
For achieving the above object, this utility model is taked following technical proposals:
Counnter attack streaming transfusion utensil connecting pipe described in the utility model, comprises the hard connection tube body that two ends are connected with infusion tube respectively, on described hard connection tube body, offers medicine-pouring hole, and the sealing of described medicine-pouring hole place is provided with flexible blockage.
Be positioned on the hard connection tube body of medicine-pouring hole bottom and be provided with antireflux chamber, described antireflux intracavity is provided with the plugging valve of conical structure, and the bottom concave surface edge of described plugging valve is provided with support salient point.
Be positioned on the hard connection tube body of medicine-pouring hole bottom and be provided with filter chamber, in described filter chamber, be provided with filter screen.
The outer wall of the hard connection tube body of close medicine-pouring hole position is matsurface.
Hard connection tube between medicine-pouring hole and antireflux chamber is arcuate structure.
The utility model has the advantage of simple in structure, avoided the local storage injury of gas to patient of leaving a blank, antireflux is effective simultaneously, can not make the anti-infusion connecting tube that flows into of blood samples of patients, during transfusion, the conical plugging valve tip of antireflux is positioned at transfusion lumen, prevent plugging valve angular displacements, the support salient point of plugging valve bottom concave surface can be avoided the transfusion lumen in its shutoff downstream, filter screen in filter chamber can avoid air and other particulate matters to enter in blood samples of patients simultaneously, and be affectedly bashful infusion connecting tube while being convenient to injection near the matsurface of medicine-pouring hole position, arc hard connection tube between medicine-pouring hole and antireflux chamber facilitates injection syringe needle to insert transfusion lumen.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, counnter attack streaming transfusion utensil connecting pipe described in the utility model, comprise the hard connection tube body 1 that two ends are connected with infusion tube respectively, on hard connection tube body 1, offer medicine-pouring hole, at medicine-pouring hole place, sealing is provided with flexible blockage 2, has omitted the Y shape injection arm of traditional design, and injection needle directly penetrates injection in tube for transfusion from flexible blockage 2, the position that there is no air storage, can not damage patient.
Be provided with antireflux chamber 3 being positioned on the hard connection tube body of medicine-pouring hole bottom, be provided with the plugging valve 4 of conical structure in antireflux chamber 3, the bottom concave surface edge of plugging valve 4 is provided with and supports salient point 5.After medicinal liquid is totally lost, the blood refluxing out promotes the bottom concave surface of plugging valve 4 by the remaining medicinal liquid of antireflux cavity rear end, plugging valve 4 is blocked tube for transfusion, and antireflux is remarkably productive.
Be positioned on the hard connection tube body of medicine-pouring hole bottom and be provided with filter chamber 6, in filter chamber 6, be provided with filter screen 7, insoluble granule residual in medicinal liquid can be filtered, avoided the injury to patient.
The outer wall of the hard connection tube body of close medicine-pouring hole position is matsurface 8, is convenient to finger and is firmly affectedly bashful infusion connecting tube, guarantees accurate injection, avoids injection needle scratching fingers.
Hard connection tube between medicine-pouring hole and antireflux chamber 3 is arcuate structure, facilitates injection syringe needle to insert transfusion lumen.
