Abstract

The utility model relates to an electronic automatic alarm for bed-wetting. The utility model uses an integrated block IC as a trigger, and the utility model also uses a triode T as an output amplifier stage. The utility model is characterized in that the input stage of the integrated block IC and leads E, F of a urine humidity switch K < 2 > are connected to A and B; the triode T is the output amplifier stage to be connected with the output stage D of the integrated block, and the triode T is also connected with a sounder Y; a potentiometer R which is used for adjusting sound volume is arranged between the sounder Y and the output stage in serial way.

Description

The automatic urine-wet alarm device of electronics

This utility model is a kind of electronics autoalarm that relates to infant and the wet clothing bedding of urine incontinence urine.

The wet clothing bedding of infant urine is common thing, and urine incontinence is not also usually because of making the clothing bedding be in dampness by self control urination.This situation makes people feel both uncomfortable, and is also unhygienic, even agonizing.Simultaneously, skin also can cause untoward reaction such as local infection or erythra because of long-term the immersion in the urine of humidity.

For releasing infant father and mother's the worry and the misery of urine incontinence, provide a kind of electronics automatic urine-wet alarm device, just become goal of the invention of the present utility model.

The automatic urine-wet alarm device of this electronics is to form with the wet K switch 2 of ic chip, audion T, sounder Y, current switch K1, potentiometer R, dc source DC and urine (with the special use urine wet tissue 1 of two leads 2,3).

It is characterized in that: the input utmost point of ic chip is associated with A, B with two leads 2,3 of the wet K switch 2 of urine; Audion T is associated with D with the ic chip output stage, and links with sounder Y for the output amplifying stage; Connect between sounder Y and output stage and adjust the potentiometer R of volume.

The wet K switch 2 of urine is to utilize medium (cotton, paper, the cloth etc.) conductivity principle of band urine, to be fixed in the special-purpose urine wet tissue 1 and to stretch out the energy conducting and making when urine is wet of outer two leads 2,3 of urine wet tissue.

Because the effect of ic chip, the automatic urine-wet alarm device sensitivity of this electronics is very high, and several urines can be reported to the police.

The automatic urine-wet alarm device of this electronics can be informed in time that infants' parents, urine incontinence or medical personnel handle and be urinated, and changes clean clothing, bedding or diaper, removes infants' parents or patient's worry and misery.Its both practical health, comfortable again convenience, and safe and reliable.

Fig. 1 is the layout of the automatic urine-wet alarm device of this electronics.

Fig. 2 is the sketch map of the wet K switch 2 of urine.It is to constitute by being fixed on two break line 2,3 in the special-purpose urine wet tissue 1 and that stretch out outside the urine wet tissue 1.

Now in conjunction with the accompanying drawings this utility model is further described:

Before the use, energized K switch 1, when urine splashed into urine wet tissue 1, break line 2,3 conductings in the urine wet tissue (promptly the wet K switch 2 of urine is connected) triggered ic chip, amplify through audion T output, and sounder Y reports to the police.Potentiometer R makes the volume of warning adjustable, is convenient to user and selects only volume.Alarm signal is just ceaselessly reported to the police once generation, and up to closing urine-wet alarm device K switch 2 (promptly more renewing urine towel) or powered-down K switch 1, sounder Y just stops to report to the police.

Fig. 3 is the complex chart of Fig. 1, Fig. 2.

Claims

1, the automatic urine-wet alarm device of this electronics is to be trigger with the ic chip, and audion T is an output amplifier stage, it is characterized in that: the output stage of ic chip is associated with A, B with two leads 2,3 of the wet K switch 2 of urine; Audion T is that output amplifier stage and integrated package output stage are associated with D; Connect between sounder Y and output stage and adjust the potentiometer R of volume.

2, the automatic urine-wet alarm device of electronics according to claim 1, it is characterized in that urinating wet K switch 2 is to constitute by being fixed in the special-purpose urine wet tissue 1 and stretching out urine wet tissue 1 outer two break line 2,3.
