Light-emitting component and light-sensitive element alignment are arranged in the two sides in the dropping liquid path of dropping funnel, shone by above-mentioned transfusion system
Element shines under the control of the controller, and when the medical fluid drippage in dropping funnel, medical fluid can stop light, and light-sensitive element receives a system
Signal is simultaneously fed back to controller by column light pulses signal, and controller processing obtains the dropleting speed of medical fluid, when the dropping liquid of medical fluid
When speed is zero, immediately or the delay motor of controller control after a certain period of time works, driving pushing component movement when motor works,
Pushing component then pushes adjusting star wheel movement, to prevent liquid in outlet tube from flowing, so that after medical fluid stream is empty in infusion bottle
It can be automatically stopped infusion, avoid the problem that patient blood back occurs and causes unnecessary loss and pain, improve infusion safety.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
