The panel of embodiment housing is provided with basis/rescue dosage five gear selector switches 11 (K as shown in Figure 1 2), dining dosage press button 9 (K 3) and on and off switch 13 (K 1), and interrogate Chinese percussion instrument 12, luminous tube 10, and housing Chinese medicine bag 3 belows are standard No.5 cell 1.5V * 2 set of cells 2, the medicated bag top is electromagnetic pump 5 and drift 6 thereof, piezoelectric transducer 7 is fixed in loading hose 4 opposite sides of corresponding drift, and loading hose is drawn from the housing top through holder 8.The bottom side of above-mentioned parts is control circuit boards.
Circuit structure of the present utility model illustrates in conjunction with Fig. 2, by IC 1,14Position binary counting/frequency division/pierce circuit CD 4060The injection working pulse of forming produces circuit, and its agitator foot 10 is through IC 2-1Electrical switch A and five gear selector switch K 2Connect respectively by resistance R 1-5And capacitor C 1, C 2The time constant circuit of forming, wherein B 1-3Gear is represented basic injected dose 6,12,24 unit/24 hour, B successively 4,5Gear represents to rescue injected dose per kilogram of body weight per hour 0.1 unit and 0.2 unit successively, and this hour counter output pulse is through diode D 1And capacitor C 4Meet IC 3-4Pump control circuit R/S latch 1/4CD 4043The monostable flipflop of forming.IC 1The foot 10 of agitator also is connected to through IC 2-2Electrical switch B connects by resistance R 6And capacitor C 1, C 2IC in the time constant circuit of the expression dining dosage dosage of forming, the working pulse of this hour counter 1Foot 6 outputs are through IC 2-3Electrical switch C and capacitor C 4Connect the pump control circuit, above-mentioned each electrical switch is by four bidirectional analog switch CD 4066Constitute, the current potential of each on-off control end is taken from and is controlled by dining dosage button switch K 3Selected control device IC 3-1, it is by 1/4CD 4043The trigger that the R/S latch constitutes.IC 3-2Prompting/alarm controller is also by 1/4CD 4043The trigger that constitutes is formed, and its asserts signal is taken from IC 3-4Pump control circuit outfan, reset signal is taken from through IC 4-2,3Six reverser CD 4069The piezoelectric transducer YDP output that shaping is amplified.On and off switch K 1Be provided with the noise reduction gear, K 1-5Be connected to clamp capacitor C 8, K 1-4Be connected to the IC in the acousto-optic generation circuit 4-4,5The audio oscillator input end who constitutes, IC 3-3Noise reduction light prompt device is by 1/4CD 4043The monostable flipflop that constitutes is formed, its set termination piezoelectric transducer output, and output termination light produces the IC of circuit 2-4The control end of electrical switch D, resistance R 16, R 17, capacitor C 7Provide from resetting low level.Set of cells connects electromagnetic pump through switch in the present embodiment, and each integrated circuit running voltage is by IC 5Power module MAX 756Foot 6 provides, foot 8 coils L 1Meet K 1-1,3Other structure of circuit board is described in conjunction with following work process.
The work process of present embodiment is: on and off switch K 1Put " ON " position, IC 5The 5V voltage of foot 6 makes C 14Charging, diode D 9End IC 4-4,5Agitator work, panel luminous tube D 14, news Chinese percussion instrument B all has light, sound to produce C 14Through R 19D sparks 9Conducting, therefore the start prompting only has the bright effect once of sound, 1C 5OUT is through C 10R 15Charging and discharging circuit resets prompting/alarm controller clear " 0 ", through C 5, R 8Charging and discharging circuit makes selected control device IC 3-1Clearly " 0 " reset, its foot 2 low level disjunction electrical switch IC 2-2,3, and through inverter ic 4-1And C 3, R 3Make IC 1Enumerator clear " 0 " also makes electrical switch IC 2-1Conducting makes this device be initially in basis/rescue dosage gear.At this moment IC 1Agitator, the counter works formed, its foot 3 output injection working pulses are through IC 3-4The pump control circuit makes field effect transistor V 1Conducting, electromagnetic pump move once, make prompting/alarm controller set simultaneously, D 9End, acousto-optic produces circuit working.When electromagnetic pump moved, in the time of its drift 6 extruding loading hoses 4, corresponding output one electric pulse of piezoelectric transducer YDP was through IC 4-2,3Shaping is amplified makes IC 3-2Reset, therefore every injection once promptly produces 2-3 infrasonic sound, light prompting.When electromagnetic pump or interlock circuit fault, sound, light all continue prompting and are fault alarm.
Button switch K 3Engage and be the selection of dining dosage, selected control this moment device IC 3-1Set, electrical switch IC 2-1Disjunction, IC 2-2,3Conducting, then IC 1The agitator time constant circuit changes, enumerator by foot 16 through IC 2-3Output services pulse, later process are with aforementioned, and its difference is, K switch 3Engage after D 3Make IC enumerator clear " 0 " be convenient to restart counting, simultaneously through D 4Straight news Chinese percussion instrument B and the light emitting diode D of giving 14, its sound, light are the prompting of dining dosage.K switch 3IC during joint 1Oscillator frequency obviously improves about 9 seconds of cycle, and rolling counters forward finishes, D 2Output is with selector IC 3-1Reset.
When sleep, using this device, on and off switch K can be placed the noise reduction shelves, at this moment, capacitor C 8Make diode D 9Clamper can not be ended in low level, then IC 4-4,5Agitator can not be worked, and sound produces circuit and is blocked, the every action of electromagnetic pump this moment once, piezoelectric transducer output will make the set of noise reduction light prompt device, its output makes electrical switch IC 2-4Connect light emitting diode D 14Bright, IC subsequently 3-3From the D that resets 14Go out, so the electromagnetic pump action once, the glittering prompting of luminous tube once.
When battery voltage is lower than IC 5When detecting setting value, these circuit pins 4 output low levels are through IC 4-6Make sound, light produce circuit working after anti-phase and change battery with the prompting user.
This utility model injected dose adjusting range is very wide, is embodied in selector switch K 2Basal dose B 1-3But the gear permutation and combination forms ten kinds of dose values, rescues gear E 1, E 2Also can be used in combination and produce 24 kinds of various dose values with basic gear, dining dosage gear can with other gear by manually being used in combination, can produce dose value more than hundred kinds.
The utlity model has following remarkable advantage: 1, have and rescue and dining dosage gear, not only can Be used for patient's Heal Thyself, also can be widely used in hospital and do basic medical equipment, 2, ID transfers Whole setting range is wider, is applicable to that the different symptoms patient uses, and can satisfy the pancreas islet of present international popular Plain intensive treatment needs; 3, have start injection, dining dosage, fault, the low-voltage prompt facility, And the sleep silencing function, use safer convenience; 4, volume is little, is easy to carry complete machine work The reliability height.
