Abstract

The utility model relates to a sensor for urine and excrement, which comprises a sensor and an alarm, wherein, the sensor is composed of two sets of circuits which are arranged in mutually parallel. An alarm circuit has two kinds of different design, one kind of design of the alarm circuit comprises a light emitting diode display and a buzzer or a loudspeaker which is pushed to sound by a transistor, and the other kind of design of the alarm circuit is a wireless coding and transmitting circuit. The alarm circuit can be matched with the sensor to be installed on diapers and to be used on human bodies. Nursing personnel can get urine and excrement signals within the set distance range so as to replace the diapers and enhance nursing effect.

Description

Sensor for urineand bowel

The utility model relates to urinates just perceptron, relates in particular to a kind of be contained on the diaper and can the perception user urine takes place and just send signal, so that the perceptron of nurse personnel assist process.

Urinate the baby that looked after by the people and nurse of again can not people by oneself normally needing just out of control, or plant person, or paralytic, or Alzheimer patient, or other patients (following general designation diaper end user), because nurse these diapers end user need drop into very big energy and muscle power, the urine that especially will know these diapers end user is just, noted when more taking and in time handled, otherwise diaper end user's buttocks or crotch are easy to that just eczema takes place or the dermatoses that festers.Thereby once had a kind of being used on the diaper to urinate just urine sensor on the market in order to the perception end user, this urine sensor by in the housing in addition the electronic package of perception and voice signal constituted, its housing area is equivalent to two ten NT dollars approximately.Perception diaper end user urine function is just seemingly arranged on this kind urine sensor surface, but it is in fact little because of the perceptron volume, deviation takes place in the position with urinating just as its detection position, make to lose the perception effect, the structure because of perception and voice signal is arranged in the same housing again, if the nurse personnel are not at the scene, just be difficult to hear signal and timely assist process, and its shell is the hardware thing, and safe not to the utmost anxiety is arranged in the use, so the main cause that can not extensively be used for this kind urine sensor.

The purpose of this utility model is to provide a kind of perception sensitivity, alarm in time, effectively to urinate just perceptron.

Another purpose of the present utility model be to provide a kind of safe in utilization, feel just perceptron of comfortable urine.

To achieve these goals, the hard perceptron of urine of the present utility model comprises a sensor and an annunciator, described sensor is made of two groups of mutual parallel circuit of strip, the circuit of described annunciator is promoted to make light emitting diode shinny by transistor, and by loudspeaker or hummer sounding, or via the coding integrated circuit send the wireless high-frequency signal; Described sensor is placed on the diaper, the urine that takes place in order to perception diaper end user just, annunciator is then in order to notify medical personnel to assist more changing babies' napkin.

Adopt just perceptron of urine of the present utility model,,, because sensor adopts flexible material to make, have advantages such as softness, safety during use again so improved the responsive effect of perceptron because its sensitive area of sensor that wherein is installed on the diaper increases.In addition, urine of the present utility model just perceptron is provided with an annunciator owing to other, when urinating just signal, sensor senses can produce sound and light signal or radio high-frequency coding signal, so the nurse personnel that can in time remind end user or notice to be positioned at setpoint distance carry out diaper change.

Below in conjunction with drawings and Examples to urine of the present utility model just perceptron be described in further detail.

Fig. 1 urinates the just sensor synoptic diagram of perceptron for the utility model;

Fig. 2 urinates the just circuit diagram of an annunciator of perceptron for the utility model;

Fig. 3 urinates the just circuit diagram of another annunciator of perceptron for the utility model;

Fig. 4 urinates the just use synoptic diagram of perceptron for the utility model.

See also Fig. 1 to Fig. 3, urine of the present utility model is perceptron just, comprises sensor 1 and

annunciator

2,3.

Sensor 1(sees also Fig. 1) constituted by two groups of P.e.c. that are arranged in parallel alternately of strip, this circuit can be made on the flexible circuit board, and is extremely thin and soft, can be placed on the diaper.When urinating just, parallel circuit is just influenced by urine and makes two lead end generation resistance change, because this perceptron is a strip, if be placed on when using on the diaper, its length and width and human body are urinated just, and happening part adapts, correctly perception is urinated just and unlikely the error, and this sensor should be in the use can be abandoned or reusable sensor.

Annunciator 2(sees also Fig. 2) circuit mainly be to utilize transistor Q ₁And resistance R ₁The just action of perceptron is urinated in the circuit perception, via coil such as the capacitor C of output transformer OT ₂With transistor Q ₁Form oscillatory circuit, this oscillator signal through output transformer to promote loudspeaker SP sounding, during the perceptron action, the also luminous demonstration of LED, testing button T ₁, be usefulness as test annunciator circuit operation.The annunciator working power is by battery B ₁Supply.

When sensor 1 perception was urinated just, the LED of annunciator 2 was shinny, and loudspeaker SP also sounds, and personnel in time assist more changing babies' napkin with the notice nurse.Urinate when just perceptron is implemented, sensor 1 can place on the diaper, and annunciator 2 can place the diaper end user by the side of, and between sensor 1 and the annunciator 2, only needing has the wiring of clip to connect (as shown in Figure 4) with two leads and two ends.

Another annunciator 3(sees also Fig. 3) circuit mainly be to utilize transistor Q ₃And variable resistor VR ₁Circuit is urinated the just action of sensor 1 with perception.Because transistorized promotion, make relay R L ₁Action, the action of relay tip makes scrambler IC ₁Action, this IC ₁Output signal is again through transistor Q ₂Produce high-frequency wireless signals (about 320MHZ), this high-frequency signal is launched via the ring-type printed circuit antenna on the circuit board.Coding is by toggle switch DIP ₁Set.Button PB ₁It is the set button that original state is replied in the action back.

When sensor 1 perception is urinated just, annunciator 3 can be launched the wireless high-frequency signal of coding, medical personnel are on one's body as long as the identical receiver 4(of band coding sees also Fig. 4), then can learn and urinate just signal with interior (surplus setting 20 rice in) at certain distance, and can assist more changing babies' napkin of diaper end user, improve the nurse effect.

In sum, being configured to of the utility model is not seen before, its sensor is that strip can improve perceived effect, its annunciator can be contained on one's body the diaper end user, the nurse personnel all can learn in certain distance and urinate just signal generation part, can alleviate the burden of nurse personnel spirit and muscle power, and improve the nurse effect.
