Description
Technical field
The utility model designs medical instruments field, specifically a kind of flow regulator.
Background technology
Traditional flow regulator is externally provided with pulley and limitation track in woven hose, by adjustable pulley on limitation track
The state that is extruded of position adjustments woven hose, so as to realize the control of liquid flowing speed in woven hose.This method accuracy compared with
Difference, can only be observed and be adjusted by the drop frequency of drop in doctor and nurse's observation transfusion funnel, both inaccurate or not
Convenient, for the less more accurate medicine of some consumptions, traditional flow regulator is not applied to more.
Patent CN101905046B realizes the accurate adjustment of flow there is provided a kind of micro-dose flow regulator, but it is tied
Structure is complicated, and the operability and stability of especially use need further improve.
Therefore it provides a kind of precision is higher, indicative flow regulator more preferable, that operability is higher is current medicine instrument
The very active demand of field in the market.
Utility model content
The purpose of this utility model is to provide a kind of high flow regulator of simple in construction, simple to operate, stability.
The technical solution of the utility model is：
A kind of flow regulator, including upper shell, lower house and rubber cushion, it is same by connecting shaft between upper shell and lower house
Axle is connected, and the end face of upper shell and the end face of lower house are oppositely arranged, and the rubber cushion is annular, and rubber cushion is located at upper shell and lower casing
Between body and around connecting shaft, the end face of the upper shell is provided with inlet opening, and rubber cushion is fixed relative to upper shell, correspondence on rubber cushion
Inlet opening is provided with through hole, and lower house is provided with the annular groove of width gradual change, and the wide end of groove is provided with fluid hole, and through hole is around connection
The rotary motion trace of axle is engaged with annular groove, and the end face docking of upper shell and lower house forms Flow-rate adjustment space, decoction
Inlet opening is entered by the feed tube of upper shell, the through hole docking of inlet opening and rubber cushion, decoction enters the end of lower house by rubber cushion
Face, makes the through hole of rubber cushion be docked with the part of the different in width of the annular groove on lower house end face, realizes flow by rotation
Regulation, Flow-rate adjustment maximum position is that through hole is corresponding with the fluid hole of lower house.
Drain pipe is provided with the lower house at correspondence fluid hole, the drain pipe outer wall is provided with anti-slip veins.Lower house pair
The conduit that the drain pipe answered is connected has certain deadweight under gravity, conduit is had certain landing risk, prevents
The setting of sliding line greatly reduces this risk.
Feed tube is provided with the upper shell at correspondence inlet opening, the feed liquor pipe outer wall is provided with anti-slip veins.On feed tube
Anti-slip veins it is possible to prevente effectively from flow regulator is with entering the risk that fluid catheter is separated.
The anti-slip veins are spiral anti-slip veins, and the projecting height of the anti-slip veins is 0.1-0.5mm；
It is preferred that, the projecting height of the anti-slip veins is 0.3mm.Spiral anti-slip veins are relative to annular anti-slip veins, its spiral
Characteristic contribute to feed tube and drain pipe on sheathed catheter, relative to the utility model have higher applicability.This practicality is new
The flow regulator of type is mainly used in the regulation control of trace drug, and feed tube and the conduit being matched therewith are often relatively thin,
Therefore, the highly desirable accurate setting of anti-slip veins, 0.3mm height can both meet anti-skidding demand, thinner feed liquor is adapted to again
The requirement of pipe.
The external diameter gradual change of the feed tube is set, and is outwards tapered by inlet opening, the external diameter gradual change of the drain pipe is set
Put, be outwards tapered by fluid hole.The gradual change setting of feed tube and drain pipe be engaged with anti-slip veins make conduit be easier with
Feed tube is connected with drain pipe, and further enhancing the stability of connection.
The utility model has the advantages and positive effects of：Due to using above-mentioned technical proposal, feed tube and drain pipe
Connection with conduit is more stablized.

Embodiment
As shown in Figure 1 and Figure 2, a kind of flow regulator of the utility model, including upper shell 1, lower house 2 and rubber cushion 3, on
Coaxially connected by connecting shaft 5 between housing 1 and lower house 2, the end face of upper shell 1 and the end face of lower house 2 are oppositely arranged, institute
It is annular to state rubber cushion 3, and rubber cushion 3 is positioned at ring between upper shell 1 and lower house 2 and around connecting shaft 5, and the end face of the upper shell 1 is set
There is inlet opening, rubber cushion 3 is fixed relative to upper shell 1, correspondence inlet opening is provided with through hole 4 on rubber cushion 3, lower house is provided with width gradual change
Annular groove 6, the wide end of groove 6 is provided with fluid hole 9, and through hole 4 matches around the rotary motion trace of connecting shaft 5 with annular groove 6
Close, the end face docking of upper shell 1 and lower house 2 forms Flow-rate adjustment space, and decoction enters feed liquor by the feed tube of upper shell 1
