Abstract

The utility model discloses a bed-wetting alarm device. The major technique conception lies in that conductive rubber is used as a sensing probe for collecting the bed-wetting signals and conduction an electronic switch, and an audio oscillator starts oscillation causing a sound circuit to sound and alarm. The utility model has the advantages of simple structure, low cost, and convenient carrying, which is suitable for use in family nursing and hospitals.

Description

A kind of enuresis alarm

The utility model relates to a kind of warning device.Relate in particular to a kind of medical treatment and nursing warning device.

Hemiplegia, aphasia patient are very high at China's various places incidence of disease at present, and are ascendant trend year by year.Can not initiatively tell after this class patient enuresis and the entourage cause nursing difficulty.Cause very big painful and burden for family, individual.

Goal of the invention of the present utility model provide a kind of simple in structure, cheap, can directly enter the enuresis alarm that family uses.

In order to achieve the above object, the solution of the utility model employing is: two conductive rubbers spaced apart from each other are placed under the diaper, are connected with alarm body by lead then.Alarm body is made up of electronic switch, audio frequency oscillator and microphone device.

Owing to adopted above-mentioned structural design, the utlity model has simple in structure, cheap, convenient carrying, suitable residential care and hospital use.

After adopting this device, can in time remind entourage patient's enuresis, should be in time changing babies' napkin more.Even if under the situation that the entourage falls asleep, its sounding also is enough to wake up with a start the paramedic, reaches above-mentioned warning purpose.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Accompanying drawing is the electrical schematic diagram of an embodiment of the present utility model;

In electrical schematic diagram shown in the drawings, D1, D2, be two conductive rubbers spaced apart from each other, as the probe sensor that detects the enuresis, be wired to plug, socket K, when being serially connected in after one of BG1 base stage probe D1 is subjected to wet with another probe D2, resistance between two probes descends immediately, BG1 produces base current, make the BG1 saturation conduction, because the conducting of BG1, form the base current of BG2, make the autotransformer reaction type audio frequency oscillator starting of oscillation of forming by BG2 and transformer B etc., promote loudspeaker and send chimes of doom.If the base current of BG1 is too little or be zero, then BG1 ends, not starting of oscillation of audio frequency oscillator, and alarm is noiseless.

Sensor probe D1, D2 are connected with electronic switch BG1 base stage by lead by plug, socket K again, and the collector of BG1 is received the base stage of autotransformer reaction type audio frequency oscillator BG2 by resistance R 1, and the collector of BG2 is received the end of autotransformer B.The emitter of BG1, the centre tap of B and acoustical generator Y1 are connected to the negative pole of battery.

Certainly, physical circuit does not limit to the cited circuit of embodiment.So long as other circuit variations that utilize conductive rubber to make enuresis sensor all should fall into protection domain of the present utility model.

Claims

1, a kind of enuresis alarm is mainly formed alarm body by electronic switch, audio frequency oscillator and microphone device, it is characterized in that: two conductive rubbers spaced apart from each other are placed under the diaper, are connected with alarm body by lead then.

2, a kind of enuresis alarm according to claim 1, it is characterized in that: D1, D2, be two conductive rubbers spaced apart from each other, as the probe sensor that detects the enuresis, sensor probe D1, D2 are connected with electronic switch BG1 base stage by lead by plug, socket K again, the collector of BG1 is received the base stage of autotransformer reaction type audio frequency oscillator BG2 by resistance R 1, and the collector of BG2 is received the end of autotransformer B; The emitter of BG1, the centre tap of B and acoustical generator Y1 are connected to the negative pole of battery.
