Abstract
The utility model relates to a transfusion alarm, which belongs to the field of medical devices. The utility model is composed of a clamp which is clamped on the lower part of a transfusion device dropper and is provided with a launching tube and a photoresistor, and an alarm main body which is arranged on a bed head, wherein a circuit board is arranged in the alarm main body; the circuit board is provided with a voltage regulator, a transfusion alarm circuit and a power supply alarm circuit; the launching tube and the photoresistor, which form a signal circuit for the main body, are connected with the voltage regulator, the transfusion alarm circuit and the power supply alarm circuit. The transfusion alarm can be free from the limitation of the light irradiation conditions of a transfusion place and can remind patients and medical staff of carrying out transfusion operation in time, which avoids the occurrence of conditions, such as blood regurgitation, thrombus formation, etc.
Description
1, technical field: infusion alarm of the present utility model belongs to the medical apparatus field.
2, background technology: the patient must observe transfusion device dropper liquid level constantly in transfusion, and the place illumination condition of being infused is sometimes limit, and is very difficult to observe.Transfusion at the end, clear-headed as patient self, at one's side nobody accompany and attend to or medical personnel not at the scene not temporarily, then easily produce blood back, form adverse consequences such as thrombosis.
3, summary of the invention: the purpose of this utility model is to propose a kind of infusion alarm that can in time report to the police before transfusion finishes.
The purpose of this utility model is achieved in that infusion alarm is by being clamped in transfusion device dropper bottom and being equiped with transmitting tube and the clip of photoconductive resistance and alarm body two parts of being installed on the head of a bed are formed.Circuit board is housed in the alarm body, is laid with manostat, transfusion warning circuit and power supply alarm circuit on it.Transmitting tube and photoconductive resistance are that main body is formed signal circuit, link to each other with the power supply alarm circuit circuit with manostat, transfusion warning circuit.When liquid level in the dropper descends, the transmitted intensity of dropper promptly changes, the photoconductive resistance resistance also changes thereupon, causes voltage comparator both sides variation in voltage in the transfusion warning circuit, thereby makes Music Clip, light emitting diode sounding and light warning respectively.
The place illumination condition is limit because employing technique scheme, this infusion alarm just can not infused, and can in time remind patient and medical personnel to carry out transfusion operation, has avoided the appearance of situations such as blood back, formation thrombosis.
4, description of drawings: concrete structure of the present utility model is provided by following drawing and description
Fig. 1 is the infusion alarm structural representation
Fig. 2 is the infusion alarm circuit diagram
5, the specific embodiment:
Legend: 1, infusion bottle 2, tube for transfusion 3, dropper 4, clip 5, lead 6, alarm body 7, manostat 8, signal circuit 9, voltage comparator 10, transfusion warning circuit 11, power supply alarm circuit 12, light emitting diode 13, Music Clip 14, photoconductive resistance 15, transmitting tube 16, resistance
Embodiment: shown in Fig. 1-2, infusion alarm is by being clamped in dropper 3 bottoms and being equiped with the clip 4 of 940 type transmitting tubes 15 and 5528 type photoconductive resistance 14 and alarm body 6 two parts of being installed on the head of a bed are formed.Be equiped with circuit board in the alarm body 6, be laid with manostat 7, transfusion warning circuit 10 and power supply alarm circuit 11 on it.Transmitting tube 15 and photoconductive resistance 14 are formed signal circuit 8 for main body, and this circuit is connected with manostat 7, transfusion warning circuit 10.Transfusion warning circuit 10 is made up of MAX953 type voltage comparator 9, TE1400 type Music Clip 13, light emitting diode 12, and wherein Music Clip 13 and light emitting diode 12 parallel connections are again with voltage comparator 9 series connection.Power supply alarm circuit 11 is made up of voltage comparator 9, light emitting diode 12.Signal circuit 8 and power supply alarm circuit 11,10 parallel connections of transfusion warning circuit.
During use, clip 4 is sandwiched in dropper 3 bottoms, makes transmitting tube 15 and photoconductive resistance 14 positions be lower than dropper 3 interior liquid levels and get final product.When liquid level in the dropper 3 descends, the transmitted intensity of dropper 3 promptly changes, the resistance of photoconductive resistance 14 also changes thereupon, causes voltage comparator 9 both sides variations in voltage in the transfusion warning circuit 10, thereby makes Music Clip 13, light emitting diode 12 sounding and light warning respectively.When infusion alarm voltage was lower than rated value, 12 of the light emitting diodes in the power supply alarm circuit 11 were lighted warning.
Claims (2)
1, a kind of infusion alarm, by being clamped in transfusion device dropper bottom and being equiped with transmitting tube and the clip of photoconductive resistance and alarm body two parts are formed, it is characterized in that: circuit board is housed in the alarm body, be laid with manostat, transfusion warning circuit and power supply alarm circuit on it, transmitting tube is that the signal circuit that main body is formed links to each other with the power supply alarm circuit circuit with manostat, transfusion warning circuit with photoconductive resistance.
2, infusion alarm as claimed in claim 1 is characterized in that: the transfusion warning circuit is made up of voltage comparator, Music Clip and light emitting diode, and wherein Music Clip and light emitting diode parallel connection connected with voltage comparator again.
