Technical field
The utility model belongs to medical instruments field more particularly to a kind of Anti-reflux infusion device.
Background technology
Common transfusion device and negative-pressure type infusion device are many with simple in structure, the resistance good, compact of bacterium effect etc.
The irreplaceable feature of positive pressure type infusion device institute, but since plain edition infusion device and negative-pressure infusion apparatus terminate in infusion
While removing Luer taper, liquid meeting reverse flow, causes in blood backflow to remaining needle, to form thrombus under suction function
Risk so that such type joint can not be widely applied；In addition, in clinical transfusion, since medical staff's carelessness has infusion
Empty risk is dripped, if air enters human body and can cause air embolism.Simple compact, the operation letter of this Anti-reflux infusion apparatus structure
If list is used in conjunction with common transfusion device, it can prevent blood backflow from generating negative pressure, if being connect with common transfusion pipeline can prevent from dripping
Sky, securely and reliably.
Utility model content
The purpose of this utility model is to provide a kind of Anti-reflux infusion device, which has simple in structure, use
The features such as convenient, safe.
In view of this, the utility model provides a kind of Anti-reflux infusion device, and technical solution is as follows：
A kind of Anti-reflux infusion device, wherein silicone valve (2) are assembled in what is be made of upper shell (1) and lower housing (3)
In main cavity, silicone valve (2) circumference and epicoele intracoelomic cavity inner wall concentric fit, bottom surface are placed in the support plate of lower housing cavity
(11) on, upper shell (1), lower housing (3) are assembled into one, when external infusion instrument or needleless joint are filled with Anti-reflux infusion
When putting connection, since the pressure difference between liquid to be transfused and blood of human body is just, silicone valve (2) moves down, and gets through liquid
Access flows freely into for liquid, and liquid flows through the reeded inner cavity of band (8) of upper shell, liquid medicine flow slot (10), outside Rule
Cone (6) flows into support plate (11) and is input in other connectors of rear；When stopping infusion, liquid drop sky or since syringe is extracted
When generic needle free connector generates negative pressure, since the pressure difference between liquid to be transfused and blood of human body is negative, pressure below pushes away at this time
Dynamic silicone valve (2) is close on upper shell (1) and attaches to upper shell (1) inner cavity muscle position (7), blocks liquid medicine flow passages,
Realize counterflow-preventing function.
Preferably, the silicone valve (2) is made of elastic rubber material.
Preferably, silicone valve (2) bottom is installed in main chamber body.
Preferably, the upper shell (1) and lower housing (3) are assembled into one use.
Preferably, the upper end lateral surface of the upper shell (1) is helicitic texture.
Preferably, the top of the lower housing (3) is equipped with locating groove (9).
Preferably, it is equipped in the upper shell (1) with reeded inner cavity (8).
Preferably, circumference is equipped with liquid medicine flow slot (10) on lower housing (2) bottom surface.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is
Some embodiments of the utility model, for those of ordinary skill in the art, in the premise of not making the creative labor property
Under, it can also be obtained according to these attached drawings other attached drawings.

Specific embodiment
The Anti-reflux infusion device includes the main cavity being made of upper casing (1) and lower housing (3), is mounted with inside main cavity
The inner core being made of silicone valve (2), upper shell (1) upper end is equipped with Rule inner cone (4), Rule inner cone outer wall is equipped with screw thread (5),
Lower housing lower end is equipped with Rule outer cone (6), connect locking for the locked joints with transfusion instrument, upper shell (1) is hollow, in Shandong
It is provided be bonded the close muscle position (7) for preventing adverse current with silicone valve (2) below your inner cone (4), in the circumference of muscle position lower section
Wall is provided with the reeded inner cavity of band (8) to position silicone valve position, is equipped in lower housing (3) inner cavity on to be packed into
The locating groove (9) of housing, liquid medicine flow slot (10), lower housing (3) lumen centers are equipped with hollow support plate (11), silica gel valve
Piece (2) is made of elastic rubber material.
When Anti-reflux infusion device access pipeline, infusion since the pressure of the liquid above it is more than the pressure of lower section liquid
Power or blood pressure, upper liquid flow through Rule inner cone (4) and silicone valve (2) are pushed to move down opening infusion access, liquid flow afterwards
