After perfusion tube normal infusion starts, equipment is mounted on perfusion tube.Perfusion tube is fixed by the infusion tube seat of equipment.
Booting: long-pressing key 3 seconds, work light was evergreen, and device power-up enters normal operation.Single-chip microcontroller is as master control core
Piece starts the data of acquisition 10 seconds to two light intensity sensors.When the data of second sensor acquisition are as normal infusion,
The luminous intensity a reference value for the light source that the light intensity sensor that medical fluid is full of under perfusion tube state receives；The number of first sensor acquisition
It periodically drips according to medical fluid, there is periodic variation.It is normal as perfusion tube by the period of change of detection acquisition data
The cycle time a reference value of pot Chinese medicine drop drippage is dripped when infusion.Main control chip sends out the two two a reference values by wireless module
Host computer is sent to be shown；
Judgment mechanism:
State 1: when equipment works, when reaching at first light intensity sensor if there is bubble, the first light intensity sensor data meeting
Since optical path interference is lower than first light intensity a reference value, single-chip microcontroller is alarmed after capturing this variation.
State 2: when equipment works, if without medical fluid, the horizontal plane of medical fluid fast prompt drop in perfusion tube in medicine bottle
It is low, when liquid level is lower than first light intensity sensor.In optical path due in perfusion tube liquid become air and larger change occur,
First light intensity sensor data accordingly changes, and is lower than first luminous intensity a reference value, and single-chip microcontroller captures this change
It alarms immediately after change.
State 3: when equipment works, when medical fluid is not when perfusion tube flows, perfusion tube drips drop in pot and stops drop for a long time
It falls.Second light intensity sensor is by long-time monitoring less than light intensity mechanical periodicity.It is longer than second period time reference when the time
When value, single-chip microcontroller is alarmed immediately.
Product structure design described in the present embodiment realizes double density black out chamber, to avoid external light source from interfering；Detection
Light source uses common white light weak light source；Using white light weak light source and the mutual secondary evidence of infrared weak light source；Motor is controlled using single-chip microcontroller
Automatic-clamping perfusion tube, whereabouts of going forward side by side liquid；Light intensity variation is detected using light intensity induction, realizes the monitoring to state.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, this field is common
Other modifications or equivalent replacement that technical staff makes technical solution of the present invention, without departing from technical solution of the present invention
Spirit and scope, be intended to be within the scope of the claims of the invention.
