Technical Field

The invention relates to automatic detection and communication, in particular to application of the technology in family or hospital child care.

Background

there are many kinds of baby diapers, such as cloth diapers, paper diapers, and the like. Because the skin of the baby is tender, some babies easily cause diaper rash (red buttocks) at the part where the diaper is padded, the skin of the baby is damaged, infection is caused, and erosion frequently occurs, so that the diaper needs to be changed frequently, and the diaper needs to be changed once wet.

The requirement that the infant "diaper is changed once wet" is an important measure to protect the health of the infant and is a fundamental requirement for parents and hospital care personnel. In order to help parents of babies or nursing staff in hospitals to find that the baby diapers are wet in time, people have invented that a 'urine wet indicating strip' or a label of 'urine display' is arranged on the diaper or the paper diaper.

The urine sample is generally made by combining a hot-melt type urine sample gel and a substance which has a sensitive color change to pH value. When urine is wetted by urine, the pH value changes, and the color change occurs.

However, there are many problems with this "urinalysis" technique.

Firstly, reliability, the urine on the new diaper or the urine on the paper diaper often changes color. This open-up discoloration is a normal feature of the urine display material itself and is not a counterfeit. This is because urine appears to be sensitive to moisture, humidity, etc. in the surrounding environment and may change from an originally yellow color to a blue or green color upon contact. In order to be convenient for mothers to use, the packaging bag of the paper diaper is provided with a tearing line and a seal, and is not completely sealed. So that the humidity of the ambient air rises even without opening the packaging bag, and may cause small green or blue spots on the diaper urine display strip in the packaging bag.

In addition, the diaper or the urine on the diaper can not indicate the amount of urine, and the function of indicating the amount of urine is data which is very needed by a doctor after operation for calculating the body fluid balance of the child.

most importantly, timeliness is required which must be met by the technology for the purpose of "diaper change on wet". Urine display technology is only a display technology, but has no monitoring function, so that the defect of insufficient timeliness is a fatal defect of the technology. People are generally busy, particularly nursing staff in hospitals, and can not always observe whether the urine wetness indicating strip changes color or not, and often people find that the color of the urine wetness indicating strip actually makes a baby wet for a long time and can cause injury to the baby sometimes.

disclosure of Invention

The invention aims to provide a urine wet alarm system which can overcome the defects of poor reliability and incapability of estimating urine volume and insufficient timeliness in the prior art, has high reliability and can estimate the urine volume and reliably perform timeliness. Since urine is a liquid with electrolytes, there is a very significant difference in the resistance between dry and wet diapers, with a high resistance when dry and a low resistance when wet and a lower resistance when wet. The value of the resistance also allows a rough estimate of the urine volume. The present invention provides a method for measuring the resistance of a diaper by using a soft and safe urine wetness detection sensor placed in the interlayer of the diaper to implement real-time urine wetness monitoring and urine volume estimation. The small-size bluetooth communication presss from both sides the volume very little like the button form, and it can press from both sides on the urine is wet to survey the inductor to pass through bluetooth relay equipment to the diaper resistance data that the urine is wet to be surveyed the inductor and detect and convey special or the nurse guardianship terminal of hospital to the cell-phone. The special APP of cell-phone or hospital nurse guardianship terminal can show the urine volume of estimation, the wet signal of urine. The invention also discloses a data processing and display mode with rich alarm of the urine volume and the urine wet signal of the APP special for the mobile phone or the hospital nurse monitoring terminal.

The technical scheme for realizing the purpose is as follows:

A soft safety urine wet alarm and urine volume estimation system comprising:

The system comprises a soft safe urine wet detection sensor, a small Bluetooth communication clip, Bluetooth relay equipment, a special APP for a mobile phone or a hospital nurse monitoring terminal;

The soft safe urine wet detection inductor is placed in the intermediate layer of diaper, and small-size bluetooth communication presss from both sides and is used for receiving the resistance signal on the diaper that the urine wet detection inductor detected and passes through bluetooth communication module to the resistance data on the diaper that detects on the urine wet detection inductor, and bluetooth relay equipment conveys cell-phone or hospital nurse guardianship terminal. The mobile phone receives the diaper resistance value of the soft safe urine wet detection sensor through a special mobile phone APP or a hospital nurse monitoring terminal to carry out binarization processing. When the resistance value of the diaper is smaller than a certain threshold value, the mobile phone or the nurse monitoring terminal sends out sound-light alarm signals or mobile phone vibration signals for urine wet alarm in real time to indicate related personnel to change the diaper for the baby in time,

the threshold value can be set on a mobile phone or a hospital nurse monitoring terminal according to the experience and the actual demand of people.

The small-size bluetooth communication presss from both sides uses small-size button cell power supply, to baby's safe and reliable. In order to prolong the service time of the small button battery and reduce the power consumption, a timing ultra-narrow window measurement scheme is adopted, so that the service time of the small button battery can be greatly prolonged. The timed ultra-narrow window measurement scheme is not continuous measurement, and is measured every half minute to several minutes, and the time window of each measurement is very narrow and can be from several microseconds to several milliseconds, so that the use of electric energy is very little.

Detailed Description

The invention will be further explained with reference to the drawings.

referring to fig. 1, the soft safety urine wetness alarm and urine volume estimation system of the present invention is shown. The soft safe urine wet detection sensor 2 is placed in the interlayer of the diaper 1, and the small Bluetooth communication clip 3 is clamped on the urine wet detection sensor 2 to receive the diaper signal detected by the urine wet detection sensor. Transmitted to a mobile phone or a hospital nurse monitoring terminal 8 through the bluetooth relay device 6 via the internet 7 through the small bluetooth communication clip 3. After the mobile phone receives the diaper signal of the soft safe urine wet detection sensor 2 through the special mobile phone APP or the hospital nurse monitoring terminal, the mobile phone or the nurse monitoring terminal sends out an acousto-optic alarm signal or a mobile phone vibration signal 5 for urine wet alarm in real time to indicate related personnel 4 to change the diaper 1 for the baby in time,

As shown in figure 2, two parallel conductive electrodes 2 are adhered to a flexible insulating plastic film carrier 3 to measure the resistance of a diaper. One end of the conductive electrode 2 is provided with a contact point 1 which is in contact with the small Bluetooth communication clip.

The small Bluetooth communication clip uses a standard Bluetooth communication module and standard Bluetooth relay equipment. (many manufacturers currently provide bluetooth communication modules, such as HC-05 bluetooth modules and bluetooth relay devices).
