The specific embodiment
As shown in the figure, this alarm constitutes by hitching device connection display alarm; Inverted U is hitched device 9 and is hitched outside the transfusion funnel 7 by cover hanging hole 8, in the inwall correspondence of hitching device 1-N emitter 10 and 1-N receptor 11 is set; Alarm lamp 2 is set on the panel of the machine box 1 of display alarm, drips fast synchro light 3, drips fast display screen 6, buzzer 5 and on and off switch 4, they are connected with interlock circuit on the machine box interior circuit board respectively, and this circuit is mainly connected to form by drop detection amplifying circuit 12, synchronous drop indicating circuit 13, warning circuit 14 and frequency multiplication, decoding, driving, a fast display circuit 15.
The drop detection amplifying circuit: test side VD3, the VD4 of drop infrared emission, reception detection components is by capacitor C 5 couplings, be connected to 3 feet of IC1A (LM324), 1 foot of IC1A is directly connected to 5 feet of IC1B (LM324), 7 feet of IC1B are connected to 10 feet of IC1D (LM324) by resistance R 12, IC1C (LM324) 14 feet are connected respectively to 3 feet of IC1A, 9 feet of IC1D by resistance R 9, R10.
Receive detection components as drop by drop, the variation voltage at VD3, VD4 two ends carries out two-stage by IC1A, IC1B and amplifies, and amplifies 2000 times altogether, and the 7 foot output voltages of IC1B are reached more than the 1V, and C2, C3 play the filtering radio-frequency component.
R7, R8 and IC1C form low-impedance power, except that providing the bias voltage for amplifier, also provide reference voltage for IC1D.When having drop to pass through the drop detection assembly, drop can absorb reflects infrared light, make the change in voltage of VD3, VD4, regulate the resistance of R10, R11, make 9 feet of IC1D be about 1.8V, therefore, when circuit remains static, the 8 feet output of IC1D is near high level, and when drop passed through, 8 feet of IC1D were exported a series of and synchronous positive pulse string of drop.
Synchronously 8 feet of drop indicating circuit: IC1D (LM324) are coupled to 2 feet of IC2 (NE555) by capacitor C 8, and LED 1 and R16 are connected to 3 feet of IC2.
Form synchronous drop indicating circuit by components and parts such as IC2, the positive pulse of the 8 feet output of IC1D was ganged up capacitor C 8 couplings, triggered monostable circuit LM555 (IC2), made its 3 foot export corresponding positive pulse string, and LED 1 is the speed of indication drop synchronously.
Warning circuit:
D2, D3 are connected to 5 feet of IC3B (LM324), and LED 2 and R32 are connected to 7 feet of IC3B, by 10 feet that R28 is connected to IC3C (LM324), form undervoltage warning with audion T2 and IC4; 3 feet of IC2 are connected to 12 feet of IC3D (LM324) by resistance R 17, and 14 feet of IC3D are connected to audion T1 and IC3A by resistance R 20, and IC3C and IC4 form dripless and produce warning circuit.
Elements such as resistance R 25, R26, R27, IC3B, D2, D3 are formed the undervoltage warning front end circuit.Reduction along with cell voltage, the voltage decreases of 6 feet of IC3B, and the 5 foot voltages of IC3B are constant substantially, thus it is flat to make that 7 feet of IC3B become high point by low level, the resistance of regulating R26, R27 can change the lower limit of the cell voltage of undervoltage warning, and this moment, LED 2 was lighted.
Element makeup times such as audion T1, C11, IC3A and IC3D are provided with the front end circuit of warning.The 3 foot positive pulse string signals of IC2 are added to 12 feet of IC3D, change the resistance of R18, R19, make 14 feet of IC3D also export the positive pulse string signal, be added to the base stage of T1, T1 alternate conduction and ending like this, according to the capacitor charge and discharge characteristic, the voltage at capacitor C 11 two ends is kept low level, the 1 foot output low level of IC3A.
In infusion bottle, there are not medicinal liquid or blood vessel blockage to cause medicinal liquid can not directly enter blood, both of these case can both make the funnel dripless of transfusion device produce, at this moment, 3 feet of IC2 do not have the positive pulse string signal, 14 feet of IC3D are low level, and audion T1 ends, capacitor C 11 chargings, the appearance value of adjusting R21 resistance or C11 can change the time of fire alarming of setting, when reaching R23/ (R22+R23)
*During VD, 1 foot of IC3A is turned to high level by low level, produces dripless by IC3C and IC4 music alarm integrated package and reports to the police.
When battery was under-voltage, 7 feet of IC3B output high level was by IC3C and the integrated generation battery of IC4 music alarm undervoltage warning.
Frequency multiplication, decoding, driving, a fast display circuit:
8 feet of IC1D are by capacitor C 19 couplings, be input to 1 foot of IC5A (CD40106), 4 feet of IC5B are by resistance R 33 and capacitor C 12, be input to 14 feet of IC6 (CD4046), 4 feet of IC6 (CD4046) are input to 12 feet of IC10 (CD4533), 6 feet of IC9C are connected to 10 feet of IC10 (CD4533), 11 feet of IC9E are connected to 13 feet of IC10 (CD4533), and 2,1,15 feet of IC10 are connected respectively to the earth terminal of hundred, ten of the digital display tubes of red common cathode, individual position by resistance R 40, R41, R42 and audion T3, T4, T5.
From the train of pulse of 8 feet of IC1D output through C19, R50 and IC5A, IC5B shaping input, Phase Lock Loop IC 6 (CD4046) and can preset 1/N enumerator IC7, IC8 (CD4018) and form 36 doubler.Adjust VCO oscillating capacitance C and loop filter between 6,7 feet, can make frequency loop be operated in 0.1～200Hz, R35, R36 and C14 constitute the frequency response of loop filtering network decision phaselocked loop, and IC7 and IC8 form two 6 frequency dividers.
The core of decoding, driving, display circuit is that three BCD enumerators of IC10 (CD4533) and IC11 (CD4511) BCD latch/decipher/driver for one or seven sections, inner three negative edges of CD4533 trigger the BCD enumerator with method of synchronization cascade together, every BCD counter output all has four latch, and cooperate with multiplexer, finish the timesharing output of three groups of BCD Counter Values, DS1, DS2, DS3 provides the output synchronizing signal, finishes drop and dynamically shows.
IC9A, IC9B, IC9C and C15, C16, R37, R38 form counting gate control cycle circuit, and this circuit is 1.67s, and IC9D, IC9E and C17, R39 form the scan round periodic circuit, and this circuit is 0.8ms.
This circuit is before the drop pulse enter counter, 36 process of frequency multiplication have been made, suppose that the drop per minute is that n drips, frequency is n/60Hz, then being 0.6nHz after 36 frequencys multiplication, is 1.67s because count gate time, so count pulse number=1.67*0.6n=n, equate that with the drop number of reality the numeral of Xian Shiing just in time is exactly the number of times that the drop per minute drips like this.
K switch is as on and off switch on the panel, and LED 1 is the speed of indication drop synchronously, and LED 2 is as the under-voltage indication of battery, and LED 3 produces the indication of reporting to the police as dripless, and buzzer is pointed out as audible alarm.
