Description
[technical field]
The present invention relates to a kind of regulating system of tube for transfusion flow.
[background technology]
Existing tube for transfusion flow control system changes tube for transfusion generally by manual adjustable pulley or by electromagnetic valve
Diameter, thus changing the infusion flow of tube for transfusion, but manual regulative mode can not accurately change tube for transfusion flow, generally needs
Repeatedly to adjust and repeatedly to can be only achieved user's request flow velocity, increased the workload of user, on the other hand, using the tune of electromagnetic valve
Section mode, the very power consumption of this regulative mode, unfavorable and long-time use, in the case of power supply deficiency, adjust and lack accuracy.
[content of the invention]
Instant invention overcomes the deficiency of above-mentioned technology, there is provided a kind of regulating system of tube for transfusion flow, turned by motor
Moved end drives screw rod to rotate, and screw rod will be converted into the translation of slide block, and the change in location using slide block changes tube for transfusion pipe
The diameter in chamber, realizes the regulation of tube for transfusion flow.
For achieving the above object, present invention employs following technical proposal:
A kind of regulating system of tube for transfusion flow, includes tube for transfusion 1, described tube for transfusion 1 be respectively provided on two sides with block 2 with
And with block 2 coordinate change tube for transfusion 1 diameter slide block 3, described slide block 3 be sequentially connected with movable slider 3 translation screw rod 4,
With screw rod 4 rotate code-disc 5, detection code-disc 5 rotational angle code-disc rotational angle detector 6, by code-disc rotational angle detect
Device 6 detection angles are converted into the transducer 7 of slide block 3 displacement, the controller 8 of receiving converter 7 Displacement Feedback information and controlled
The motor 9 that device 8 processed controls, described motor 9 turning end is connected with screw rod 4.
Described code-disc 5 is encoder or Hall element.
Described tube for transfusion 1 is flexible pvc pipe or flexible silicone tube.
Described controller 8 is connected with wireless communicator 10.
Described wireless communicator 10 is wifi communicator, Bluetooth communication device or infrared communication device.
Described controller 8 is connected with input keyboard 11.
The invention has the beneficial effects as follows:
1st, the present invention changes precise control tube for transfusion pipe diameter by slider displacement, reaches transfusion pipeline speed governing, pass
The effect closed or open.
2nd, the present invention and liquid in transfusion pipeline are not directly contacted with, reusable.
3rd, the present invention, with respect to electromagnetic valve energy-saving, is just to consume power supply in adjustment state, maintains tube for transfusion pipe diameter shape
Power supply need not be consumed during state.
4th, the present invention is big with respect to motor torque, small volume.
5th, the present invention effectively prevents motor rotation blockage, moves to tube for transfusion shutoff shape when code-disc rotational angle is detected for slide block
During state, cut off motor power, prevent motor rotation blockage.
6th, use the spacing equipment of potentiometer, resistive layer wear problem during such as potentiometer uses with respect to steering wheel etc., increase
Service life.
[brief description]
Fig. 1 is the schematic diagram of the present invention.
[specific embodiment]
It is described in further detail with embodiments of the present invention below in conjunction with the accompanying drawings:
As shown in figure 1, a kind of regulating system of tube for transfusion flow: include tube for transfusion 1, described tube for transfusion 1 both sides are respectively
It is provided with block 2 and coordinates, with block 2, the slide block 3 changing tube for transfusion 1 diameter, it is flat that described slide block 3 has been sequentially connected with band movable slider 3
The screw rod 4 that moves, the code-disc 5 rotating with screw rod 4, the code-disc rotational angle detector 6 of detection code-disc 5 rotational angle, code-disc turned
Dynamic angle detector 6 detection angles are converted into the transducer 7 of slide block 3 displacement, the controller of receiving converter 7 Displacement Feedback information
8 and the motor 9 that controls of controlled device 8, described motor 9 turning end is connected with screw rod 4.
Wherein, described controller 8 is connected with input keyboard 11, and described code-disc 5 is encoder or Hall element, described defeated
Liquid pipe 1 is flexible pvc pipe or flexible silicone tube.
Operation principle is as follows:
When user inputs tube for transfusion flow regulating signal by input keyboard 11, controller 7 controlled motor 9 turning end turns
Dynamic, thus driving screw rod 4 to rotate, screw rod 4 will be converted into the translation of slide block 3, changes the distance between slide block 3 and block 2,
Reach change and be arranged at tube for transfusion 1 diameter between slide block 3 and block 2, that is, between slide block 3 and block 2, distance is less, transfusion
Pipe 1 diameter is less, and flow is less, otherwise between slide block 3 and block 2, distance is bigger, and tube for transfusion 1 diameter is bigger, and flow is bigger, with
When in screw rod 4 rotation process, code-disc 5 is also rotated with screw rod 4, and code-disc rotational angle detector 6 detects code-disc 5
Rotational angle, the rotational angle of detection is converted to slide block 3 slide displacement by transducer 7 again, and slide displacement is fed back to control
In device 8, controller 8 carrys out controlled motor 9 further according to slide displacement feedback information and rotates, until reaching the transfusion pipe flow of user input
Till value, but when slide displacement feedback information slides into tube for transfusion 1 off state for slide block 3, controller 8 cuts off motor 9
Power supply, prevent motor 9 stall, wherein motor 9 can be rotated forward or invert.
Described controller 8 is connected with wireless communicator 10, and described wireless communicator 10 is wifi communicator, Bluetooth communication device
Or infrared communication device, user wirelessly can also be adjusted by wireless communicator 10.
