Description
Technical field
This utility model belongs to medical instrument, particularly a kind of injection liquid level monitor.
Technical background
At present, patient infusion all is to monitor liquid level variation by the people in the hospital, especially the transfusion liquid level apart from syringe needle near the time, more need the people to note, in case can cause danger to patient otherwise liquid level is lower than syringe needle, will make the people nervous easily like this, and waste of manpower and time.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, and injection liquid level monitor a kind of simple in structure, easy to operate is provided.
The technical scheme that this utility model technical solution problem adopts is: a kind of injection liquid level monitor is mainly inserted body by pin type, composition such as lead and limiting stand, be characterized on the band wedge angle inclined-plane of the slotting body of pin type, being arranged with, following two holes, pass the A lead in the last hole, the B lead is passed in following hole, and secure seal, at A, be welded with metal dots or conducting resinl A on the termination of B lead respectively, the B point, A, the B metal dots is apart greater than 5mm, insert the body bottom in pin type and be provided with a concentric and horizontal conical boss, the other end of lead A passes in the concentric circular cone boss, the other end of lead B passes horizontal conical boss, respectively device taking alarm two ends; Comprise battery supply, oscillating circuit, power amplifier, audion, buzzer and resistance in the circuit theory diagrams of alarm; Positive pole, oscillating circuit and the power amplifier of another termination battery supply of A lead, the other end connecting resistance R of B lead
1An end, R
1Other end connecting resistance R
2An end, the base stage of audion, the colelctor electrode of audion connects oscillating circuit and power amplifier, power amplifier connects the buzzer two ends, the radiation utmost point connecting resistance R of audion
2The other end and the negative pole of battery supply.
The beneficial effects of the utility model are: when patient infusion, A, B metal dots or conducting resinl that pin type is inserted on the body pass through the liquid conducting, when the injection liquid level is lower than the A metal dots, will disconnect with the B metal dots, alarm will be reported to the police, remind nurse personnel or patient, the releasing people notes the buck fever of level change and works hard that this utility model is simple in structure, easy to operate, can also report to the police with musical film always, interesting to listen to melodious, help patient's rest.

The specific embodiment
Embodiment one: with reference to accompanying drawing 1,2, injection liquid level monitor is injection molded into the upper end with the hard non-toxic plastic and is the slotting body 5 of hollow pin type, insert body 5 bottoms and establish a limiting stand 7, intersect with limiting stand 7 and to establish a horizontal conical boss 6, one and slotting body 5 concentric conical boss 8 are established in the lower end, on the band wedge angle inclined-plane of the slotting body 5 of pin type, bore two holes up and down relatively, A lead 2 one ends are passed in last hole, B lead 4 one ends are passed in following hole, and secure seal, at A, B lead 2,4 top is welded with A respectively, B metal dots or conducting resinl 1,3, A, B metal dots 1,3 apart greater than 5mm, and the other end of A lead 2 is drawn from the bottom hole of concentric circular cone boss 8, and the other end of B lead 4 is drawn from the bottom of horizontal conical boss, A, B lead 2, the two ends of 4 devices 9 taking alarm, A, B metal dots 1, below 3 the voltage difference 0.5V.
Embodiment two: injection liquid level monitor can be attached on the disposable transfusion device needle for inserting bottle to be combined with disposable transfusion device, is provided with plug at A, B lead 2,4 other ends and is connected with alarm 9.
With reference to accompanying drawing 3, comprise battery supply T in the circuit theory diagrams of alarm 9, oscillating circuit Z, power amplifier G, audion V, buzzer Y, resistance R
1, R
2, A lead 2, B lead 4, its annexation is positive pole, oscillating circuit Z and the power amplifier G of another termination battery supply T of A lead 2, the other end connecting resistance R of B lead 4
1An end, R
1Other end connecting resistance R
2An end and the base stage of audion, the colelctor electrode of V meets oscillating circuit Z and power amplifier G, the radiation utmost point connecting resistance R of V
