Abstract

The invention provides a puncture connector type transfusion device. The transfusion device comprises a transfusion conduit and a venous transfusion needle, wherein a venous transfusion needle holder is arranged on the venous transfusion needle; a bottle cap puncture outfit is arranged at the front end of the transfusion conduit, a connecting tube is arranged between the transfusion conduit and the venous transfusion needle; an outer conical connector matched with the venous transfusion needle holder is arranged at the rear end of the connecting tube; a rubber plug cap is arranged at the front end port of the connecting tube; a branch tube is connected with the connecting tube below the rubber plug cap, and is connected with the transfusion conduit by virtue of a one-way valve; the joint between the branch tube and the connecting tube is less than 10cm from the one-way valve, and is less than 15cm from the outer conical connector. According to the puncture connector type transfusion device, the rubber plug cap on the connecting tube is punctured by an injection needle for quickly dosing, a liquid medicine can be prevented from returning due to the one-way valve on the branch tube at the front end of the connecting tube, so that the liquid medicine can be transfused into a human body quickly, so that time is gained for saving a patient. The puncture connector type transfusion device is reasonable in design and simple in operation, and can be used for facilitating medicine injection and preventing the occurrence of liquid medicine return.

Description

Puncture connector formula transfusion device

Technical field

The present invention relates to a kind of area of medical devices, particularly a kind of puncture connector formula transfusion device.

Background technology

Often there will be clinically the situation that needs Quick-adding medicine; while infusing as patient, there is infusion reaction and emergency unit's rescue patient such as allergy, shock; conventionally nurse's way is to disconnect being connected of intravenous needle and transfusion catheter; from the quiet medicine that pushes away of intravenous needle needle stand; but this way produces bubble in the time of can causing intravenous needle to be again connected with transfusion catheter; and troublesome poeration, has increased nurse's workload, has even delayed best rescue opportunity.Also had before this transfusion device with injection member, during still from injection member dosing, medicinal liquid, easily to upper reaches, cannot enter human body fast.The invention provides a kind of liquid medicine injection but also Quick-adding medicine formula transfusion device that can adverse current of not only having facilitated.

Summary of the invention

Technical problem to be solved by this invention is for the deficiencies in the prior art, and puncture connector formula transfusion device a kind of reasonable in design, easy to use is provided.

Technical problem to be solved by this invention is to realize by following technical scheme, the present invention is a kind of puncture connector formula transfusion device, comprise transfusion catheter and venoclysis needle, venoclysis needle is provided with intravenous needle needle stand, the front end of transfusion catheter is provided with bottle cap perforator, on transfusion catheter, be provided with successively dropping funnel and flow regulator, be characterized in: between transfusion catheter and venoclysis needle, be provided with connection tube, the rear end of connection tube is provided with the outer cone joint coordinating with intravenous needle needle stand, the front port of connection tube is provided with plug block, on connection tube below plug block, be connected with arm, arm joins by check valve and transfusion catheter, described arm and connection tube joint are less than 10cm apart from the distance of check valve, arm and connection tube joint are less than 15cm apart from the distance of outer cone joint.

Technical problem to be solved by this invention can also further realize by following technical scheme, described check valve comprises lower and upper cover, between lower seat and upper cover, be provided with valve pocket, lower seat and above cover and be respectively equipped with the infusion channel being communicated with valve pocket, in valve pocket, be provided with the gel silica membrane coordinating with the infusion channel of upper cover, in lower seat, be provided with the some support columns that support gel silica membrane.

Technical problem to be solved by this invention can also further realize by following technical scheme, and connection tube is provided with liquid medicine filter.

Technical problem to be solved by this invention can also further realize by following technical scheme, and described bottle cap perforator is provided with air inlet, and air inlet is provided with the air filter with air-filtering membrane.

Technical problem to be solved by this invention can also further realize by following technical scheme, and tongs is housed on transfusion catheter.

The plug that the present invention punctures on connection tube by entry needle is blocked a shot, carry out Quick-adding medicine, and check valve on its front end arm can prevent medicinal liquid adverse current, make medicinal liquid enter fast human body, for giving emergency treatment to a patient the time of having saved, compared with prior art, it is reasonable in design, simple to operate, when facilitating injectable drug, there will not be again the phenomenon of adverse current.
