Description

A kind of wearable device for stool and urine detection

Technical field

The utility model relates to a kind of intelligent detection device more particularly to it is a kind of for stool and urine detection it is wearable Equipment.

Background technique

Paper diaper have been widely used for infant, old man and the special population that can't take care of oneself.Due to these crowds Particularity may not necessarily also be experienced even if stool and urine has occurred, or remind other people to help and replace paper diaper.If too late Shi Genghuan not only influences personal hygiene, but also bacterium easy to breed, causes the diseases such as skin.With the reality of two tire policy of China It applies, aging populations increase and the love of special population is promoted, and require a kind of convenient, reliable and easy-to-use stool and urine inspection Device is surveyed, to improve the quality of life of these groups.

Although having some technologies to detect for stool and urine, it cannot all reach good effect, it is difficult to which satisfaction is actually answered Use demand.For example, some technical staff utilize the electric conductivity principle of urine, the stool and urine detection sensing with electrode is had developed Device, diaper and monitoring system (application number: 201710058948.6).This design has Railway Project: one, inconvenient, detection zone Domain needs to be aligned anus portion and the private parts of wearer, otherwise can fail；Two, unhygienic, sensor detection zone can connect with stool and urine Touching, cleans and reuses and is more troublesome.Some technical staff using Temperature Humidity Sensor detected magnitude just when caused temperature Carry out early warning (application number: 201510218903.1 with humidity variation；201520278197.5).It is this design the problem is that: One, poor anti jamming capability, rate of false alarm is high, and China's north-south climate difference is big, and the variation of environment temperature and humidity easily leads to sensor Wrong report, replacement clothing bring temperature and humidity variation also easily cause to report by mistake；Two, sensitivity is not high, and this kind of sensor is worn slightly not When at defecation farther out, it is difficult to detect stool and urine.There are also some technical solutions refer to using gas-sensitive sensing element come Detected magnitude just (application number: 201520550935.7), the thinking of this scheme is preferable, but only give circuit frame design, Do not account for the structure design of the characteristic and detection system of gas sensor, it is difficult to the effect that has obtained in practical applications with Experience.

Generally speaking, stool and urine detection has a good application prospect with prompting and social effect, related art scheme mention Go out good detection thinking, solves some practical problems.But from the point of view of accuracy, reliability and Experience Degree, the prior art Scheme is fully solved not yet, and commercial applications are not also significant.Therefore, there is an urgent need to one kind to cover detecting element and the system integration Comprehensive design scheme, realize accurate and reliable, convenient easy-to-use stool and urine detection system.

The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of wearing for stool and urine detection Equipment is worn, convenient for carrying.

The utility model is achieved through the following technical solutions, and the utility model includes sealed box body, detection plate and electricity Road plate offers the exploration hole for detecting extraneous smell and temperature and humidity, the detection plate and electricity at the top of the sealed box body Road plate is successively from top to bottom arranged in sealed box body, includes gas sensor, temperature sensor and humidity in the detection plate Sensor.

The sealed box body is silica gel box body.The binding part for bonding can be set in the behind of silica gel box body, it can be with Entire sealed box body is bonded on paper diaper, can also directly be placed it in pocket, or be made into pendant, stool and urine is used for Real-time monitoring.

The gas sensor is MEMS gas sensor.Gas sensor use MEMS gas sensor, high sensitivity, Fast response time has special gas and releases when stool and urine occurs, and passes through the gas of MEMS gas sensor detection release Body can be detected out stool and urine.

The circuit board includes data acquisition module, one-chip computer module, communication module and power module；The data acquisition Module connecting detection plate and the signal for acquiring each gas sensor, temperature sensor and humidity sensor, the single-chip microcontroller mould Block is separately connected data acquisition module and communication module, the electric power source pair of module whole circuit board power supply.

The communication module is bluetooth module or WIFI module.

The power module is rechargeable battery.

Temperature sensor and humidity sensor are used to detect the variation of ambient temperature and humidity, as reference data, reduce because of temperature Wrong report caused by humidity variation.Data acquisition module is used to acquire the signal of all the sensors, and is converted to digital signal.Monolithic Machine module is the control centre and data processing centre of entire detection device.Communication module writes detection and is transferred to mobile terminal Or on cloud server.Power module is rechargeable battery, provides power supply for whole equipment.All modules are integrated in one block of electricity On the plate of road, and it is encapsulated in a box body.The wearable device can be both fixed on paper diaper by way of stickup, can also It is placed in pocket, or is made into pendant, the real-time monitoring for stool and urine.

The utility model have the advantage that compared with prior art the utility model proposes for stool and urine detection can Wearable device has the features such as accuracy is high, fast response time by the distinctive gas of stool and urine itself as discrimination method； Ambient temperature and humidity variation is monitored using temperature sensor and humidity sensor, reduces the rate of false alarm of detection system；So Module is integrated on one piece of circuit board, and package dimension is small, and whole system structure is simple, accurately and reliably, convenient easy-to-use.
