The utility model discloses the during operation, the fixed bolster is connected with the range finding box, first stationary dog and the tight tail end of blocking at the injection pole of second stationary dog, infrared distance meter sends the infrared ray and receives in syringe overcoat turn-up department and blocks, will block signal output to single chip microcomputer control module, single chip microcomputer control module blocks the receipt of signal, calculate the distance that the injection pole removed, according to the syringe model with injection pole displacement conversion into liquid medicine infusion volume (for example: 50ml =7.5 cm), calculate the volume of infusing per hour according to the time difference again, show liquid medicine infusion volume and infusion speed on the LED display screen, set up the button through comparator numerical value, set up the rate of administration into the transfer pump settlement. The comparator compares the speed that the speed box surveyed the speed of dosing and the speed that the comparator set for, and when both speeds are different, warning speaker can send warning sound warning display lamp scintillation simultaneously, and the suggestion nursing staff inspects the micropump.

Furthermore, the single chip microcomputer control module is respectively and electrically connected with the power supply module, the comparator, the alarm module, the LED display module and the infrared distance meter.

Further, the comparator value setting button is electrically connected with the comparator.

Furthermore, the fixed support is provided with a connecting buckle.

Furthermore, a clamping groove matched with the connecting buckle is arranged on the distance measuring box.

The utility model adopts the above technical scheme, compare beneficial effect with prior art: the distance is converted into the liquid medicine infusion amount of the micro-injection pump of the patient through the distance measuring box, and the liquid medicine infusion amount is visually displayed through the LED display screen, so that clinical nursing personnel can read the liquid medicine infusion amount and the infusion speed conveniently, medication errors caused by different observation time intervals and inaccurate liquid medicine infusion amount reading are avoided, and the safety of the patient is guaranteed; the fixed support is of a caliper structure, one fixed claw can move on the slide bar, and the device is suitable for measuring the dosage of different types of micro pumps.
