Abstract
The utility model relates to a liquid level monitoring technique in electronic control, more specifically an automatic medical transfusion alarm. The utility model is composed of an illuminant box (3) and a receiving box (4) which are respectively arranged on mutually corresponding bottle sleeves of a transfusion bottle (1); a photosensitive control circuit which is composed of a battery, a photoresistor (R1), an adjustable resistor (R2), a driving audion (V), a relay (K) and a buzzer (B) is arranged in the receiving box (4). The utility model utilizes the light refraction principle to monitor injection physic liquor (2) in the transfusion bottle (1). The utility model has simple structure, can automatically give alarms and can reduce the labor intensity of a patient's family members and medical staff.
Description
Technical field
This utility model relates to the liquid level monitoring technology in the Electronic Control, specifically, is a kind of automatic alarm for medical transfusion.
Background technology
When patient infuses in hospital ward, often need entourage or nurse to watch infusion bottle frequently, the liquid that prevents infusion bottle drips off the back and does not pull out syringe needle and cause blood back, cause psychology frightened to patient, when patient when not having entourage or nurse on duty busy, just need patient oneself to observe infusion bottle every now and then, increased unnecessary burden to patient.
By retrieval, the existing medical infusion alarm that is used on the infusion bottle, as " the medical infusion supervising device " of Chinese utility model patent ZL01263684.3 and " automatic alarm for infusion " and the Chinese invention patent application number 02132743.2 disclosed " medical infusion alarm " of Chinese utility model patent ZL99251492.4 proposition, their structure is roughly the same, form by light emitted tube elements and photosensitive receiving element, two elements is contained in the corresponding mutually position of infusion bottle respectively, utilize the refraction principle of light to control warning circuit, drive buzzer or speaker and report to the police.Wherein the audio oscillator circuit of ZL01263684.3 is made up of the NE555 integrated package, light emitted pipe, photosensitive tube be arranged on the bottle put can put at bottle mobile.The triggering integrated package PM-011 work that ZL99251492.4 adopts, 3 volts of battery powered can link to each other with the existing call circuit of hospital.02132743.2 pair of light emitted tube elements of application number and photosensitive receiving element have proposed the use infrared transmitting tube, infrared receiving tube control news are rung circuit.Three kinds of above-mentioned circuit structures have their own characteristics each.But the circuit structure complexity, function singleness can't be expanded again, thereby use is subjected to certain restriction.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, with low cost, can expand the automatic alarm for medical transfusion of realizing combined network communication, carrying out the team control function.
The purpose of this utility model is achieved in that designed automatic alarm for medical transfusion, is contained in respectively on the corresponding mutually bottle cover position of infusion bottle by a Luminescent cases and a receiving box to constitute, and this bottle puts according to regulating needs and moves up and down; The monochromater radiated element that has resistance R 3 and single color LED D to be composed in series in the Luminescent cases; It is characterized in that: receiving box is interior by the photosensitive control circuit of being made up of battery, photoconductive resistance R1, adjustable resistance R2, driving audion V, relay K and buzzer B, wherein, photoconductive resistance R1 and adjustable resistance R2 are connected into bleeder circuit, dividing point connects the base stage that drives audion V, the colelctor electrode utmost point and the relay K coil that drive audion V join, and the normally open contact K1 of relay K connects buzzer B.
In order further to improve this utility model, the normally open contact K1 of above-mentioned relay has a plurality of, is used for expansion and realizes combined network communication, carries out the team control function.
Photosensitive control circuit in above-mentioned monochromater radiated element, the receiving box and the power supply of buzzer B provide by battery.
The automatic alarm for medical transfusion that the utility model proposes, it is to utilize the refraction of red light that the liquid in the transfusion device is detected, change according to the anaclasis of infusion bottle detection place and to judge the transfusion progress, when transfusion closes to an end, drive the relay K action immediately, connect normally open contact K1, control buzzer B sends warning, if normally open contact K1 is connected to other executive components, then can produces as communication, control electromagnetic valve and turn-off tube for transfusion
Advantage of the present utility model and effect are:
1, this utility model does not contact liquid and the patient in the infusion bottle, so patient is not had any injury, does not influence medical personnel's work yet.
2, this utility model volume is little, simple in structure, use simple and convenient.
3, reduce the unnecessary number of times of travelling to and fro between the ward of medical personnel, improved medical personnel's work efficiency, reduced medical personnel's working strength.
4, alleviated heavy burden for patient's nursing family members.

Fig. 3 is this utility model circuit theory diagrams.
Among the figure: 1 infusion bottle; 2 liquid medicine injections; 3 Luminescent cases; 4 receiving boxes; The R1 photoconductive resistance; The R2 adjustable resistance; R3 resistance; V drives audion; The D red light emitting diodes; The B buzzer; The K relay; K1, K2, K3 relay normally open contact.
The specific embodiment
This utility model is made with embodiment below in conjunction with accompanying drawing and to be further specified.
A kind of automatic alarm for medical transfusion is contained in respectively on the corresponding mutually bottle cover position of infusion bottle 1 by a Luminescent cases 3 and receiving box 4 and constitutes, and this bottle puts according to the adjusting needs and moves up and down; The monochromater radiated element (seeing accompanying drawing 3) that has resistance R 3 and red light emitting diodes D to be composed in series in (seeing accompanying drawing 1,2) Luminescent cases 3.Receiving box 4 is interior by the photosensitive control circuit of being made up of battery, photoconductive resistance R1, adjustable resistance R2, driving audion V, relay K and buzzer B, wherein, photoconductive resistance R1 and adjustable resistance R2 are connected into bleeder circuit, dividing point connects the base stage that drives audion V, the colelctor electrode utmost point and the relay K coil that drive audion V join, and the normally open contact K1 of relay K connects buzzer B; Photosensitive control circuit in above-mentioned monochromater radiated element, the receiving box 4 and the power supply of buzzer B provide by the 3V battery.
When present embodiment uses, when in the infusion bottle liquid medicine injection 2 being arranged, the irradiation of the HONGGUANG line of emission is less than on the receiving box 4 in the Luminescent cases 3, not conducting of circuit in the receiving box 4, when the liquid medicine injection in the infusion bottle 12 when Luminescent cases 3 is following, the HONGGUANG line of emission is on the refraction of vial shines photoconductive resistance R1 on the receiving box 4 in the Luminescent cases 3, audion V conducting, the relay K coil is connected normally open contact K1, and buzzer B will sound, and the prompting nurse pulls out syringe needle.This device utilizes optical principle to control alarm, can use separately, and normally open contact K2, the K3 that also can use relay links to each other with hospital existing call circuit, thereby is adapted at applying in all kinds of hospitals and the family.
