Abstract

The utility model relates to a music alarm for bed-wetting, comprising a humidity sensor, a crystal oscillator, a frequency-voltage converter, a voltage comparator, a monostable trigger, and a music buzzer. When the humidity sensor encounters wetting, voltage generated between two conducting film strips switches on the crystal oscillator so as to be changed into frequency signals. The frequency signals are changed into voltage value through the frequency-voltage converter. The voltage comparator compares the voltage value with setting voltage value and then outputs high electric potential. Positive pulse with a narrow peak value is output through the monostable trigger so that the buzzer is triggered to sound. The alarm has the advantages of convenient use, small volume, high sensitivity, and safe use, being suitable for patients with urinary and fecal incontinence.

Description

The wet music alarm of urine

The utility model relates to the wet music alarm of a kind of urine, belongs to technical field of living necessaries of humans.

The product that many protection infants are arranged in the market; diaper etc. for example; use this product, when the infant urinate wet after, urine still is adsorbed in the paper; urine steam also can stimulate tender and lovely skin; smell is also bad, simultaneously very easily in child is pedaled, and the both sides of the thigh that rubs; though mother has often avoided the more trouble of changing babies' napkin, the baby is standing speechless misery.And often a large amount of the use, also can cause burden economically.Therefore also occurred alarm device for urine wet in succession on the market, when using common diaper, can remind nurse personnel changing babies' napkin more in time,, reduced expenses again to improve comfort level.But product structure in the market is unreasonable, and volume is big, the cost height, and inconvenience goes out to carry.

The purpose of this utility model is the wet music alarm of a kind of urine of design, and with electronic circuit, integrated circuit and humidity sensor collection are one, reduce volume, reduce cost, and be easy to use.

The wet music alarm of the urine of the utility model design, comprise humidity sensor, crystal oscillator, frequency-voltage changer, voltage comparator, monostalbe trigger and music hummer, described humidity sensor is made up of non-conductive substrate and two conducting film bars, conducting film bar evaporation is on non-conductive substrate, two conducting film bar spaces, and link with crystal oscillator after stretching out from substrate one end respectively, after humidity sensor is met and is wet, the voltage that produces between two conducting film bars is connected crystal oscillator, behind crystal oscillator, become frequency signal, this frequency becomes a magnitude of voltage through frequency-voltage changer, output noble potential voltage comparator is compared this magnitude of voltage with setting voltage value after, this noble potential is exported narrow peak value positive pulse by monostalbe trigger, triggers the hummer sounding.

The wet music alarm of the urine of the utility model design; when the infant urinated wet shield, the graceful music tip caregiver changing babies' napkin more in time that can in time sound made the infant do not urinated wet misery; avoid skin to be subjected to the wet and friction of long urine, protect the dry and comfortable, comfortable of the tender and lovely skin of infant.The alarm of the utility model design can be convenient to use, and also is applicable to gatism, the patient who can't take care of oneself simultaneously, and this small product size is small and exquisite, and is highly sensitive, safe and reliable.

Description of drawings:

Fig. 1 is the circuit theory diagrams of the wet music alarm of urine of the utility model design.

Fig. 2 is the structure principle chart of the used humidity sensor of the utility model.

Below in conjunction with accompanying drawing, describe content of the present utility model in detail.

Among Fig. 1, the 1st, humidity sensor, the 2nd, negative electrode conducting film bar, the 3rd, substrate, the 4th, anodic conductive film bar, U1 are frequency-voltage changers, and U2 is a voltage comparator, and U3 is a monostalbe trigger, and U4 is the music hummer.

As shown in Figure 1, the wet music alarm of the urine of the utility model design comprises humidity sensor 1, crystal oscillator C, frequency-voltage changer U1, voltage comparator U2, monostalbe trigger U3 and music hummer U4.Humidity sensor 1 is made up of non-conductive substrate 3 and two conducting

film bars

2 and 4, conducting film bar evaporation on non-conductive substrate 3, two conducting

film bars

2 and 4 spaces, and stretch out the back from substrate one end respectively and link with crystal oscillator C.After humidity sensor is met and is wet, the voltage that produces between two conducting film bars is connected crystal oscillator, behind crystal oscillator, become frequency signal, this frequency becomes a magnitude of voltage through frequency-voltage changer, voltage comparator is compared this magnitude of voltage and is afterwards exported noble potential with the magnitude of voltage that the user sets, this noble potential is exported narrow peak value positive pulse by monostalbe trigger, trigger the hummer sounding, make the nurse personnel in time change the diaper of urinating after wetting.

Claims

1, a kind of urine music alarm that wets, it is characterized in that, this alarm comprises humidity sensor, crystal oscillator, frequency-voltage changer, voltage comparator, monostalbe trigger and music hummer, described humidity sensor is made up of non-conductive substrate and two conducting film bars, conducting film bar evaporation is on non-conductive substrate, two conducting film bar spaces, and link with crystal oscillator after stretching out from substrate one end respectively, after humidity sensor is met and is wet, the voltage that produces between two conducting film bars is connected crystal oscillator, behind crystal oscillator, become frequency signal, this frequency becomes a magnitude of voltage through frequency-voltage changer, output noble potential voltage comparator is compared this magnitude of voltage with setting voltage value after, and this noble potential passes through monostalbe trigger, export narrow peak value positive pulse, trigger the hummer sounding.
