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, which provides a kind of micro-dose flow regulator, realizes the accurate adjustment of flow, 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.
Provided with the ribs on the inside of the end face of upper shell on the inside of the end face of the upper shell, the ribs is by even
To external radiation at spindle.The setting of ribs adds the stability of upper shell end face, makes it be not easy to be come from upper shell
Stress injury between lower house end face causes it to rupture.
Stiffening ring, described ribs one end and upper shell madial wall are provided with the inside of the end face of the upper shell at connecting shaft
It is connected, the other end is connected with stiffening ring lateral wall.It is similarly subjected to come from the pressure at right angle of connecting shaft at the connecting shaft of upper shell,
Stiffening ring can effectively improve the stability of end face near connecting shaft, coordinate ribs, strengthen the resistance to overturning of end face.
The feed tube is located at the middle part of any one ribs, and feed tube with conduit due to being often connected, sheathed catheter
During entering feed tube, the pressure perpendicular to end face can be produced to feed tube, is conducted through feed tube to end face, easily causes end
The breakage in face, the base portion of feed tube is in contact with ribs, and the pressure is then largely reinforced rib decomposition, improves end face
Stability.
The projecting height of the ribs and the length ratio of ribs are 1:5-1:8；
It is preferred that, the projecting height of the ribs and the length ratio of ribs are 1:6.The length to height ratio mistake of ribs
Greatly, then the same frangibility of ribs, the declines of ribs, the length to height ratio of ribs is too small, then adds the loss of material,
The material according to used in flow regulator, the optimal length to height ratio of ribs is 6:1.
The utility model has the advantages and positive effects of：Due to using above-mentioned technical proposal, flow regulator it is steady
Qualitative higher, service life is longer.

Embodiment
As shown in Figure 1-2, a kind of flow regulator of the utility model, including upper shell 1, lower house 2 and rubber cushion 3, upper casing
Coaxially connected by connecting shaft 5 between body 1 and lower house 2, the end face of upper shell 1 and the end face of lower house 2 are oppositely arranged, described
Rubber cushion 3 is annular, 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 provided with
Inlet opening, rubber cushion 3 is fixed relative to upper shell 1, and correspondence inlet opening is provided with through hole 4 on rubber cushion 3, and lower house is provided with width gradual change
Annular groove 6, the wide end of groove 6 is provided with fluid hole, and through hole 4 is engaged around the rotary motion trace of connecting shaft 5 with annular groove 6,
The end face docking of upper shell 1 and lower house 2 forms Flow-rate adjustment space, and decoction enters inlet opening by the feed tube of upper shell 1,
The through hole 4 of inlet opening and rubber cushion 3 is docked, and decoction makes the logical of rubber cushion 3 by rubber cushion 3 and into the end face of lower house 2 by rotation
