Infrared transmitting tube 1 and receiving tube 9 are separately positioned on the both sides of Mo Feishi dropper 10, be positioned on the same axis, and with the intersect vertical axis of Mo Feishi dropper 10 in the water dropping openings below, detect transfusion fault and control speed with this.
Be with 1 on the pipe joint 6 and mould magnetosphere 7, and settle a Hall element 13 moulding magnetosphere 7 and shell 12 adjacent sides, whether install correctly in order to detect pump line.
The child moves pump installation, fuction monitoring device for infusion, pipeline clamping monitoring device and is covered by lid 34, has a transparency window 35 on the lid 34, can observe the situation of dripping of Mo Feishi pipe 10.
Embodiment 2: operation principle of the present utility model and duty
This utility model adopts motor 14 to do the discontinuous rotation for power source direct-driven pump wheel 2, roller 3 on the pump impeller 2 promptly pushes the liquid in the silica gel tube 5 that tightly is enclosed within roller 3 outsides, and around pivot pin 4 rotations, in the extrusion process, liquid under atmospheric action in transfusion bag or the infusion bottle 11 charges in the silica gel tube 5 through Mo Feishi dropper 10 step-by-step movements, the liquid that roller 3 squeezes out is input into the intestinal conduit through pipe joint 6 and tube for transfusion 8 and enters patient's enteral.
When silica gel tube 5 does not install, pipe joint 6 breaks away from shell 12 together with moulding magnetosphere 7, and Hall original paper 13 loses the magneticaction of moulding magnetosphere 7, and its outfan produces potential change, warning circuit 26 sends sound, light is reported to the police even this variation pipeline after single-chip microcomputer 16 is handled comes off, and is pointed out.
During work, nutrition pump is to be the step-by-step movement transfusion, be that motor 14 rotates, exporting a certain amount of nutritional solution rear motor 14 makes a short pause, constantly repeat then, the length of dead time depends on the speed data of keyboard 15 to single-chip microcomputer 16 inputs, per hour providing motor 14 after single-chip microcomputer 16 calculates should change how many times, can satisfy selected speed; The number that different Mo Feishi dropper 10 same speed are worked at every turn is different, the available number that number actuator 24 is regulated to work at every turn; It is that infrared sensing device 23 by infrared transmitting tube 1 and infrared receiving tube 9 compositions and infrared monitoring circuit 25 detect and feed back to single-chip microcomputer 16 and controlled that the reality of each work is dripped number, as long as measure the number that drips of setting, single-chip microcomputer 16 promptly makes motor 14 stalls through drive circuit 22, the dead time that is provided with finishes, then motor 14 begins again to rotate, so go round and begin again, finish the step-by-step movement infusion of nutritional solution.
The infrared sensing device of forming when infrared transmitting tube 1 and receiving tube 9 23 does not detect water droplet, showing that promptly transfusion finishes or pipeline blockage, and infrared circuit 25 does not have signal input single-chip microcomputer 16, and warning circuit 27 sends sound, light is reported to the police even single-chip microcomputer 16 transfusions are finished.
By keyboard 15 limit amount can be set, when nutrition pump output total amount 19 equaled limit amount 20, single-chip microcomputer 16 promptly can make display 21 Alternation Display speed 18 and limit amount 20, and simultaneously, limit amount alarm 28 sends sound, light is reported to the police, and gives prompting.
When infrared transmitting tube 1 and receiving tube 9 measure constant linear signal, show the blocking-up of output monitoring system light source, pipeline breaking or pipeline junction are thrown off, even this signal of infrared circuit 25 input single-chip microcomputers 16 failure alarm circuit 28 after single-chip microcomputer 16 is handled sends alarm signal.
Circuit of the present utility model is by regulator rectifier circuit 30 and charging circuit 31 power supplies, and by built-in dc-battery 32 power supplies, when cell voltage 32 dropped to the minimum of setting, single-chip microcomputer 16 made the under-voltage circuit 29 of battery send sound, light is reported to the police during power failure.
All Alerts sound all can be by the ventil noise reduction in the keyboard 15.Do not handle as fault in regular hour after the noise reduction, alert sound can repeat to sound.
Technical parameter:
1) speed 1ml/h～300ml/h, the following every retaining 1ml/h of 50ml/h, the above every grade of 5ml/h of 50ml/h.
2) limit amount 0.1～999ml.
3) aerofluxus fast
4) working power AC 220V 110V DC 12V battery
5) ambient temperature is 10～40 ℃, relative humidity≤80%.
Need not further to elaborate, believe and adopt the disclosed content in front, those skilled in the art can use the present invention to greatest extent.Therefore, the preferred specific embodiments of front is interpreted as only illustrating, but not limits the scope of the invention by any way.
