Abstract

The utility model is a urine wet acoustic and optic indicating device relating to a daily life article. As shown in the attached picture, the acoustic and optic indicating device is composed of a humidity sampling device, a switch circuit and an indicating circuit controlled by the switch circuit. When bedwetting happens for babies or patients, the indicating device makes sound and light indications so that the nurses can deal with that in time. As a result, babies and patients won't suffer from the urine dip.

Description

The wet acousto-optic hint device of urine

The utility model is a kind of daily necessities, promptly a kind of urine acousto-optic hint device that wets.

Bed-wetting is baby and patient's a common phenomenon, as untimely processing, can damage people's skin, influences people's rest.Just want in time to handle and to find that in time will in time find just must constantly observe, the difficulty of monitoring is very big.In order to address this problem, the someone adopts absorbent material to make and inhales and urinates product, but still can't resolve the problem of injured skin.

To be that development is a kind of sound and light the prompting device of pointing out the paramedic in time to handle to the purpose of this utility model at once after bed is wet by urine.

Above purpose is realized by following technical scheme: develop the wet acousto-optic hint device of a kind of urine, this prompting device is provided with a humidity sampler, and the humidity sampler connects an on-off circuit, acousto-optic hint circuit of on-off circuit control.

Said humidity sampler has upper and lower two wire nettings, clamps a slice insulating mat between two wire nettings.

Said on-off circuit is made of triode, current-limiting resistance, switch relay and power supply.

Said cue circuit is adjusted resistance, triode, loudspeaker and power supply by light emitting diode, current-limiting resistance, Music Clip, volume and is constituted.

Said cue circuit can be made of light emitting diode and resistance.

The wet sound and light display of the urine that adopts technique scheme to make is established appropriate location in bed with the humidity sampler, in case that sampler is urinated is wet, prompting device will send light and sound, and the prompting paramedic in time handles.

Introduce a kind of embodiment below in conjunction with accompanying drawing:

Fig. 1 is the circuit theory diagrams of present embodiment, and Fig. 2 is humidity sampler structure figure.

As can be seen, the sampler of humidity shown in R _x, test resistance R ₁, Test Switchboard K ₁, sensitivity reconciles resistance R ₂, sampling triode T ₁, current-limiting resistance R ₃, be worth resistance R partially ₄, signal amplifying triode T ₂, relay J, overvoltage protection diode D ₁, decoupling capacitor C ₁, light emitting diode D ₂, current-limiting resistance R ₅, Music Clip CHO2, volume adjust resistance R ₆, music amplifying triode T ₃, relay switch JK, loudspeaker Y, on-off circuit power supply DC ₁, acousto-optic circuit power supply DC ₂, master switch K ₂, go up wire netting 1, insulating mat 2, wire netting 3, lead 4 down.

Wet and when being drying regime by urine when the humidity sampler, last wire netting 1 and following wire netting 3 are insulated and fill up 2 and separate and be open-circuit condition, T ₁Base stage can not obtain inclined to one side threshold voltage, then T ₁Collector and emitter end R ₃The two ends potential difference (PD) levels off to 0, then T ₂Base stage can not obtain inclined to one side threshold voltage, T ₂Emitter and collector also end, then J can not adhesive, makes acousto-optic circuit be in stopped status.

As humidity sampling thief R _xAfter quilt urine was wet, last wire netting 1 and following wire netting 3 conductings made T ₁Base stage obtain inclined to one side threshold voltage, its collector and emitter conducting, T ₁-collector potential decline, T ₂Base stage pass through R ₄Obtain inclined to one side threshold voltage, its collector and emitter conducting, the adhesive of relay J device makes the JK closure, overcurrent protection diode D ₁The overcurrent protection light emitting diode D that is used for J ₂Luminous, current-limiting resistance R ₅Be used to light emitting diode D ₂Current limliting, Music Clip CHO2 sends music signal simultaneously, adjusts resistance R by volume ₆Deliver to music amplifying triode T ₃Base stage, pass through T ₃Collector promote loudspeaker Y and send music.K ₂For the complete machine self-lock switch, has only K ₁Entire circuit just can be worked K when closed ₁Whether be the Test Switchboard of no self-locking, being used for test circuit can operate as normal.Resistance R is reconciled in sensitivity ₂Be used for reconciling the working sensitivity of humidity sampler.On-off circuit power supply DC ₁Be used for supplying with on-off circuit work, the acousto-optic circuit power supply is used for supplying with acousto-optic circuit work.
