Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of reasonable in design, and injection is needleless connector formula transfusion device easily.
Technical problem to be solved in the utility model is to realize by following technical scheme, this utility model is a kind of needleless 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 end of connection tube joins by check valve and transfusion catheter, on connection tube, be provided with arm, 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, in described arm, be provided with rubber stopper, rubber stopper is provided with feed pathway, and the top of feed pathway is provided with the elasticity valve coordinating with entry needle, and it is automatically closed that entry needle is extracted rear elasticity valve.
Technical problem to be solved in the utility model 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 in the utility model can also further realize by following technical scheme, and the end of arm is provided with block, and block is connected with arm by screw thread.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and the transfusion catheter in check valve front is provided with liquid medicine filter.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and the connection tube of arm and rear end, connection tube joint is provided with liquid medicine filter.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and tongs is housed on transfusion catheter.
This utility model joins medicinal liquid in connection tube by feed pathway fast by the entry needle with draw point not, and the check valve of connection tube front end 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, when entry needle is not with draw point to avoid operating in addition, stab nurse, there is the phenomenon of cross infection, the puncture exfoliation of interface of simultaneously can avoiding puncturing enters in liquid road and blood circuit, 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.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of arm.
Detailed description of the invention
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
