Abstract
The utility model provides an automatic alarm for an infusion bottle, which has the advantages of high anti-jamming capability and reliable work. The utility model is composed of a casing which can place a bottle and an interior circuit. The interior circuit is composed of a power circuit, a transmitting circuit, a reception amplifying circuit, a phase locking circuit, and an alarm circuit. The utility model is characterized in that the infrared emission and the infrared reception can be used, and the phase locking circuit is used for controlling controlled silicon to switch on, and the music alarms. The utility model has the advantages of high anti-jamming capability and reliable work.
Description
This utility model relates to electronic alarm, and exactly, it is the infusion bottle autoalarm that is used for hospital.
Existing infusion bottle is when treating that liquid will be totally lost, and is observed by the people, makes the nurse pull out tube for transfusion then, and manual monitoring is very inconvenient.Now also useful light emitting diode is made alarm, but anti-interference is poor, and is unreliable, can't apply.
The purpose of this utility model provides the infusion bottle autoalarm of the strong reliable operation of a kind of capacity of resisting disturbance.
Its technical scheme is as follows: it is made up of the circuit in the shell that can place bottle and the shell.Circuit is made of five parts.(1) power circuit, the alternating current of 220V, transformator (B), bridge rectifier (Do) and three terminal regulator (IG1) and filter capacitor (C1, C2) constitute; (2) radiating circuit is made of resistance (R1), infrared transmitting tube (D1), integrated package (IC2), amplifying triode (BG1); (3) receive amplifying circuit, constitute by resistance (R2, R3, R4, R5, R6, R7), electric capacity (C3, C4, C5), infrared receiving tube D2, amplifying triode (BG2); (4) phase lock circuitry is made of integrated package (IC2), electric capacity (C6, C7, C8), resistance (R8, R10); (5) warning circuit, by controllable silicon (BCR), music audion (VT), stabilivolt (D3), electric capacity (C9), and resistance (R9, R11, R12) constitute.
Owing to adopted phase lock circuitry, can compare external input signal and local frequency, when phase place is identical, but just conducting alarm, so it is anti-interference and reliability is high.This alarm can directly adopt alternating current, and range of application is big.
Be illustrated below in conjunction with drawings and Examples:
Fig. 1 is this utility model circuit structure diagram.(housing is picture slightly)
As shown in Figure 1: circuit is divided into five parts.First's power circuit.Power supply is made up of 220V alternating current, transformator B, bridge rectifier D o and three terminal regulator IC1 and filter capacitor C1, C2.The second portion radiating circuit.Form by R1, D1, IC2, BG1.From the oscillator signal of IC2 foot, after audion BG1 amplifies, outwards launch infrared signal by infrared transmitting tube D1.Third part receives amplifying circuit.Form by R2, R3, C3, D2, R4, C4, R5, R6, BG2, R7, C5.Infrared receiving tube D2 becomes the infrared signal that receives into the faint signal of telecommunication, after R4, C4 input amplifier tube BG2 amplifies, by C5 output, enters the 3. foot of IC2.The 4th part phase lock circuitry.Be made up of IC2 and peripheral cell C6, C7, C8, R8, R10, it compares external input signal and local frequency, when the phase place of importing the 3. extraneous signal of foot is identical with the local oscillation signal phase place, its 8. the output voltage of foot by high step-down.The 5th part warning circuit.Form by R9, C9, BCR, D3, R11, R12, VT, loudspeaker bifurcation etc.After infrared signal was cut off, IC2 8. foot output HIGH voltage after second, triggered controllable silicon BCR conducting through C9 time-delay 1-2.Form power supply at stabilivolt D3 two ends.Music audion VT outputting music signal promotes loudspeaker and sends music, and stand by lamp L1 is bright simultaneously.L2 is the normal condition display lamp.R13 is the divider resistance of L2.
