Description
Technical field
The utility model is related to the field of medical instrument technology, and in particular to minim pipette flow speed controller.
Background technology
Intravenous transfusion device is a kind of common medical treatment consumptive materials, by aseptic process, establishes channel between vein and liquid, is used
In venous transfusion.Generally by intravenous needle or injection needle, needle-covering cap, injection hose, liquid medicine filter, flow speed controller, drop pot,
The part such as bottle plug puncture unit, air filter connection composition, infusion segment device also have injection member, dosing mouth etc..Under the prior art
Injection hose on flow speed controller be to be sleeved in injection hose, operation principle be idler wheel slide on the inclined tracks,
Change the spacing between idler wheel and the panel of flow speed controller, to press to injection hose, so that injection hose is generated deformation and carry out
Flow velocity is adjusted, but idler wheel is easy free to slide on the inclined tracks, causes flow velocity naturally to become larger, patient is made to feel not
It is suitable.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of simple in structure, design conjunction is provided
Reason, minim pipette flow speed controller easy to use, it includes band cap screw rod, cylindrical plastic bar;In the cylindrical plastic bar
Equipped with inclined dropping liquid pipe through-hole;It is equipped in cylindrical plastic bar and with the female circular hole of band that cap screw rod matches, band
Screw-type is flexibly connected between cap screw rod and circular hole;The end with cap screw rod is flat-head shape;External screw thread with cap screw rod is complete
When portion rotates into circular hole, the end with cap screw rod is pushed up at the upper wall of dropping liquid pipe through-hole;The band cap screw flight bar
Diameter be greater than or equal to dropping liquid pipe through-hole diameter.
With the above structure, the utility model has the beneficial effect that:Minim pipette flow speed controller described in the utility model,
It uses the screw design of screw-pushing type, squeezes the minim pipette in dropping liquid pipe through-hole, and minim pipette is made to generate deformation, to adjust drop
The circulating rate of liquid medicine in liquid pipe;It can prevent the flow velocity in minim pipette from voluntarily becoming larger in dropping liquid.
Description of the drawings
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute improper limits to the present invention, in the accompanying drawings:
Fig. 1 is the utility model structure diagram;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the sectional view of the parts A-A in Fig. 2.
Reference sign:
1- band caps screw rod, 2- cylindrical plastics bar, 3- circular holes, 4- dropping liquid pipe through-holes.
Specific implementation mode
Be described in detail the utility model below in conjunction with attached drawing and specific embodiment, illustrative examples therein with
And explanation is only used for explaining the utility model, but be not intended to limit the scope of the present invention.
As shown in Figs. 1-3, the minim pipette flow speed controller described in present embodiment, it includes band cap screw rod 1, cylinder
Shape plastic bar 2;Inclined dropping liquid pipe through-hole 4 is equipped in the cylindrical plastic bar 2;It is equipped in cylindrical plastic bar 2 and with cap
The female circular hole 3 of band that screw rod 1 matches, screw-type is flexibly connected between band cap screw rod 1 and circular hole 3;The band cap spiral shell
The end of bar 1 is flat-head shape;When external screw thread with cap screw rod 1 is all rotated into circular hole 3, the end top with cap screw rod 1 is arrived
At the upper wall of dropping liquid pipe through-hole 4;The diameter of the threaded rod with cap screw rod 1 is greater than or equal to the diameter of dropping liquid pipe through-hole 4.
Further:The annular surface of the front end socket cap with cap screw rod 1 is equipped with cross non-skid thread, cross
The design of non-skid thread increases the friction coefficient with 1 front end socket cap of cap screw rod, convenient for rotating band cap screw rod 1 with finger.
Further:The annular surface of the cylindrical plastic bar 2 is equipped with cross non-skid thread;Cross non-skid thread
Design improves the friction coefficient on 2 surface of cylindrical plastic bar, is adjusted convenient for grasping cylindrical plastic bar 2.
Further:The cylindrical plastic bar 2 is the plastic bar of degradation plastic material, and degradation plastic is to environment
Less pollution.
Minim pipette flow speed controller described in the utility model, its operation principle are:Disposable vein is made in producer
When infusion apparatus, dropping liquid hose is pierced into dropping liquid pipe through-hole 4, then this flow speed controller can be regarded common flow control
Device carries out subsequent intravenous transfusion device processing and manufacturing;When using the intravenous transfusion device comprising this flow speed controller, by normal
Operating method is infused to human body, only when needing to carry out flow control, can just use this practicality minim pipette flow control
Device, at this time one hand hold cylindrical plastic bar 2, then pinching the front end socket cap with cap screw rod 1 with thumb and index finger is turned
Dynamic, band cap screw rod 1 is promoted into circular hole 3 while rotation, and dropping liquid hose will be squeezed in lasting progradation, keeps dropping liquid soft
Pipe generates deformation, to change the liquid medicine flow velocity in minim pipette;Since band cap screw rod 1 and circular hole 3 use screw-type connection, tie
Structure is stablized, and the dropping liquid hose reseting elasticity of itself can not push band cap screw rod 1 to move out, therefore during being not in dropping liquid
Flow velocity voluntarily becomes larger.
Minim pipette flow speed controller described in the utility model, it uses the screw design of screw-pushing type, squeezes dropping liquid
Minim pipette in pipe through-hole makes minim pipette generate deformation, to adjust the circulating rate of liquid medicine in minim pipette;It can prevent minim pipette
In flow velocity voluntarily become larger in dropping liquid.
The above description is only a preferred embodiment of the present invention, therefore all according to described in the utility model patent application range
The equivalent change or modification done of structure, feature and principle, be included in the scope of the utility model patent application.
