Description
Technical field
This utility model relates to a kind of gas or liquid hose speed regulator, particularly the flexible pipe speed regulator of venous transfusion.
Background technology
For venous transfusion, not only its infusion tube is not rigid body but also very thin, be difficult to flow regulator is installed, when adopting electronization to control, also be difficult to install suitable motor and Flow-rate adjustment module, therefore, roller type speed regulator generally used by the flexible pipe speed regulator of venous transfusion, degree of regulation is low, and range of accommodation is little.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of magneto flexible pipe fluid speed regulator, and the fluid conveying that thinner flexible pipe can be adopted to carry out to venous transfusion etc. is carried out accurately, speed governing on a large scale.For this reason, this utility model is by the following technical solutions:
Magneto flexible pipe fluid speed regulator, it is characterized in that, described speed regulator is provided with motor, the rear side of described flexible pipe is provided with permanent magnet, the front side of flexible pipe is provided with the rotating and fluid speed governing element that can be attracted by described permanent magnet, speed governing member motion described in step motor drive, and control the suction-combining force between speed-regulating part and permanent magnet with this, described speed governing element carries out flow rate regulation by squeezing tube, and described permanent magnet is used for speed governing element to the extruding of flexible pipe to the captivation of speed-regulating part.
Described speed regulator is provided with limit shaft, described speed governing element is enclosed within limit shaft by long guiding hole, in speed regulation process, described speed governing element to coordinate with limit shaft at long guiding hole and the route of defined carries out seesawing relative to described flexible pipe and rotates as fulcrum using described flexible pipe.
Described speed governing element leans against on described flexible pipe from the side, forms the seesaw structure using described flexible pipe as fulcrum.
Described motor and venous transfusion sensor sample model calling, the work of motor controls by venous transfusion sensor sample module.
Described speed governing organs incline leans against on front side of described flexible pipe, and described motor connects pushing member, described pushing member act on described speed governing element away from that side of flexible pipe, described speed governing element can be attracted by permanent magnet near this side of flexible pipe.
Owing to adopting technique scheme, this utility model carries out speed regulating control by the extruding of rotating speed governing element to flexible pipe, can mainly rely on permanent magnet captivation to carry out speed governing, the role of control then mainly played the part of by motor, even if the motor of small-power, small size also can enable speed regulator normally work, speed governing is accurate, speed adjustable range is large.This utility model can make speed governing element moving linearly superpose the motion of rotational motion, and forms seesaw type working method, such that structure is more simple, speed governing more accurately and improve sensitivity.And this utility model can use venous transfusion sensor sample module control step machine operation, can realize the accurate speed governing of automatization.This utility model not only may be used for flow rate of liquid and regulates, and due to highly sensitive, can also carry out the adjustment of gas flow rate.

Detailed description of the invention
With reference to accompanying drawing.Magneto flexible pipe fluid speed regulator provided by the utility model is provided with motor 5, when being applied to infusion set, described flexible pipe 1 is infusion tube, the rear side of described flexible pipe is provided with permanent magnet 2, the front side of flexible pipe 1 is provided with fluid speed governing element 4 that is rotating and that can be attracted by described permanent magnet 2, motor 5 drives described speed governing member motion by the mode be connected with motor shaft by speed-regulating part, and change the suction-combining force between speed-regulating part 4 and permanent magnet 2 with this, this connection can adopt the mode of nut-screw, namely screw rod is driven by motor and rotates, the convert rotational motion of screw rod is rectilinear motion by nut, speed-regulating part is connected with nut or one, thus by actuation movement.
Described speed governing element 4 carries out flow rate regulation by squeezing tube 1, and the captivation of described permanent magnet 2 pairs of speed-regulating parts 4 is used for the extruding of speed governing element 4 pairs of flexible pipes 1.
Described speed regulator is provided with limit shaft 3, described speed governing element 4 is enclosed within limit shaft 3 by long guiding hole 40, and to coordinate with limit shaft 3 at long guiding hole 40 under the driving of motor 5 and the route of defined carries out seesawing relative to described flexible pipe and be fulcrum with flexible pipe.
Described motor and venous transfusion sensor sample model calling, the work of motor controls by venous transfusion sensor sample module.
Described speed governing element 4 can adopt the iron plate perpendicular to described flexible pipe 1.
Described speed governing element 4 leans against on described flexible pipe 1 from the side, forms the seesaw structure using described flexible pipe as fulcrum.
In above-mentioned seesaw structure, described speed governing element 4 tilts to lean against on front side of described flexible pipe, also be, described motor connects pushing member 7, described pushing member 7 and the connection of motor also can adopt the mode of above-mentioned nut-screw, and pushing member can be exactly this nut or be connected with this nut, pushing member act on described speed governing element away from that side 41 of flexible pipe, described speed governing element can be attracted by permanent magnet 2 near this side 42 of flexible pipe.This kind of structure, structure is very simple, is very easy to install.
When forward drive made by motor 5, when promoting the equilibrium point of speed governing element 4 to seesaw form, the moment of thrust and the magnetic attraction equalising torque of permanent magnet, speed governing element 4 moves forward to extreme position, speed governing element is near permanent magnet, the suction-combining force between permanent magnet 2 and speed governing element 4 is maximum, and flexible pipe 1 is flattened blocking-up completely, and this process flow velocity slows down gradually until close.When motor 5 drives push mechanism to retreat, the suction-combining force between permanent magnet 2 and speed governing element 4 reduces, the flexible pipe flattened is replied, and by speed governing element to pusher until just do not leant against on flexible pipe by its crimp, the flow velocity in this process flexible pipe 1 tunes up gradually.
