Abstract

The invention provides a needleless connection type infusion apparatus. The needleless connection type infusion apparatus comprises an infusion catheter and an intravenous infusion needle between which a connection pipe is arranged; an external taper joint in match with an intravenous infusion needle holder is arranged at the rear end of the connection pipe; the front end of the connection pipe is connected with the infusion catheter through an one-way valve; a branch pipe is arranged on the connection pipe; the distance from the part in which the branch pipe is connected with the connection pipe to the one-way valve is less than 10cm, and the distance to the external taper joint is less than15cm; a rubber plug on which a liquid inlet channel is positioned is arranged in the branch pipe; an elastic valve in match with an infusion needle is arranged on the top of the liquid inlet channel; the elastic valve can be automatically closed after the infusion needle is pulled out. According to the needleless connection type infusion apparatus, medicine liquid is quickly added to the connection pipe through the infusion needle without a steel needle, the one-way valve at the front end of the connection pipe can prevent the medicine liquid from reverse flowing, thus the medicine liquid can quickly enter a human body; in addition, the infusion needle without the steel needle can prevent a nurse from being punctured to cause cross infection.

Description

Needleless connector formula transfusion device
Technical field
The present invention relates to a kind of area of medical devices, particularly a kind of needleless connector formula transfusion device.
Background technology
Often need to patient, carry out the quiet medicine that pushes away by transfusion device clinically.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 and troublesome poeration can cause intravenous needle to be again connected with transfusion catheter time; increase nurse's workload, even delayed best rescue opportunity.For the transfusion device with injection member, nurse also can dosing from injection member, but during from the dosing of dosing part, medicinal liquid is easily to upper reaches, and the position of dosing part is reasonable not, and medicinal liquid cannot enter human body fast.And puncture with the syringe with draw point, draw point may be stabbed nurse and be occurred cross infection.In piercing process, there will be the puncture exfoliation of the interface that punctures to enter liquid road and blood circuit, may increase the risk that microorganism enters liquid road and blood circuit in addition.
Summary of the invention
Technical problem to be solved by this invention 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 by this invention is to realize by following technical scheme, the present invention 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 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 the end of arm is provided with block, and block is connected with arm by screw thread.
Technical problem to be solved by this invention can also further realize by following technical scheme, and the transfusion catheter in check valve the place ahead is provided with liquid medicine filter.
Technical problem to be solved by this invention 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 by this invention can also further realize by following technical scheme, and tongs is housed on transfusion catheter.
The present invention fast joins in connection tube by medicinal liquid by feed pathway 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, the phenomenon that occurs 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.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is the structural representation of arm.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
See figures.1.and.2, a kind of needleless connector formula transfusion device, comprise transfusion catheter 4 and venoclysis needle 12, venoclysis needle 12 is provided with intravenous needle needle stand 11, the front end of transfusion catheter 4 is provided with bottle cap perforator 1, described bottle cap perforator 1 is provided with air inlet, and air inlet is provided with the air filter with air-filtering membrane.
On transfusion catheter 4, be provided with successively dropping funnel 3 and flow regulator 5, on transfusion catheter 4, tongs 2 can also be housed.Between transfusion catheter 4 and venoclysis needle 12, be provided with connection tube 9, the rear end of connection tube 9 is provided with the outer cone joint 10 coordinating with intravenous needle needle stand 11, the front end of connection tube 9 joins by check valve 7 and transfusion catheter 4, on connection tube 9, be provided with arm 8, described arm 8 and connection tube 9 joints are less than 10cm apart from the distance of check valve 7, arm 8 and connection tube 9 joints are less than 15cm apart from the distance of outer cone joint 10, are conducive to like this medicinal liquid and enter fast human body.In described arm 8, be provided with rubber stopper 13, rubber stopper 13 is provided with feed pathway 14, and the top of feed pathway 14 is provided with the elasticity valve coordinating with entry needle, and it is automatically closed that entry needle is extracted rear elasticity valve.When using, syringe needle tube is by elasticity valve, and by drug injection, to feed pathway 14, medicinal liquid enters human body fast by connection tube 9.Inject the automatic closure of rear taking-up entry needle elasticity valve and sealed the top of feed pathway 14.Because there is check valve 7 can prevent medicine adverse current, make medicine enter fast human body, for giving emergency treatment to a patient the time of having saved.Use the entry needle of needleless can facilitate nurse to carry out Needleless dosing, reduce nurse's workload, reduced again the probability of cross infection simultaneously.
