Detailed Description

The utility model discloses it is with high costs to aim at solving current intelligent disposable diaper, leads to unable commercialization to use to and bulky, influence use comfort's defect. The novel intelligent paper diaper and the paper diaper replacement reminding system are provided. The disposable diaper described in this application refers to disposable diapers in various shapes such as a sheet shape, a pants shape, and the like. Because be disposable, and change the frequency height, so its cost must be low just to have the practicality, simultaneously because the user need wear for a long time, so the influence of the intelligent detection circuit of increase to the comfort level will be as little as possible.

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

Referring to fig. 1 to 3, the intelligent diaper comprises a diaper body 40 and a sensing module 10 for detecting urination and defecation, wherein the sensing module 10 comprises an inductor 11, an NFC chip 12 and an NFC antenna 13, and the NFC chip 12 is connected to the inductor 11 and the NFC antenna 13 respectively.

The sensor 11 is preferably an impedance sensor, and when there is urine or stool on the diaper, the resistance value changes, and the resistance value changes with the change of the humidity of the diaper, so that it is possible to judge whether there is urine or stool on the diaper and judge the humidity of the diaper by sampling the output value of the impedance sensor. In this embodiment, the impedance sensor specifically employs a first conducting wire 111 and a second conducting wire 112 arranged at intervals, the first conducting wire 111 and the second conducting wire 112 are connected to the NFC chip 12, when urine or feces exists in a diaper area between the first conducting wire 111 and the second conducting wire 112, a resistance value of the area changes, and the resistance value changes with a change in humidity, and the change is transmitted to the NFC chip 12. Two leads are adopted as the inductor 11, so that the cost is further reduced on one hand, and on the other hand, the influence on the use comfort of the diaper can be further reduced by adopting sheet leads such as copper foils and flexible circuit boards.

Further in this embodiment, the inductor 11, the NFC chip 12 and the NFC antenna 13 are disposed on a flexible substrate 14, and the flexible substrate 14 is sandwiched between two layers of the diaper body 40. The diaper body 40 generally comprises multiple layers, preferably two layers of the diaper body 40 comprising a surface layer adjacent to the human body, so that the sensitivity of the sensing is better. Flexible substrates 14 that may be used include, but are not limited to, flexible circuit boards, sheets of cloth, and sheets of paper. The NFC antenna 13, the first wire 111, and the second wire 112 may be directly printed on the flexible substrate 14, or may be formed on another substrate and then fixed to the flexible substrate 14 by means of adhesion or the like. The flexible substrate 14 is preferably secured to the diaper body 40 by, but not limited to, gluing, sewing, etc.

Referring to fig. 4, the system for reminding replacement of disposable diapers includes: the sensing module 10 is configured on the diaper body 40 and used for detecting excrement and urine, the sensing module 10 is composed of a sensor 11, an NFC chip 12 and an NFC antenna 13, and the NFC chip 12 is respectively connected with the sensor 11 and the NFC antenna 13; a detection device 20 having an NFC host 21 and a short-range wireless communication module; and a personal terminal 30 having a short-range wireless communication module.

For convenience of description, the short range wireless communication module in the detection apparatus 20 is referred to as a first short range wireless communication module 22, and the short range wireless communication module in the personal terminal 30 is referred to as a second short range wireless communication module 31.

The sensing module 10 is implemented as in the previous embodiment.

The first short range wireless communication module 22 and the second short range wireless communication module 31 that can be used include, but are not limited to, a bluetooth module, a WiFi module. Preferably, the Bluetooth module is equipped, or the Bluetooth module and the WiFi module are equipped, the Bluetooth module can be suitable for outdoor environments and the like without a wireless local area network, the Bluetooth has a one-way broadcasting system, and multi-channel receiving of mobile phone App (Application program) can be supported, so that one guardian can manage a plurality of monitored persons, and the system is suitable for Application environments such as baby rooms and nursing homes.

The personal terminal 30 is preferably a smart phone, a smart band, or a smart ring. The personal terminals 30 are not only worn on the guardian for a long time, but also have various reminding modes such as sound, vibration, display and the like, so that missing reminding can be reduced.

The detection device 20 is preferably constructed as a bracelet, ring, or the like, so that it can be conveniently worn on the body of a diaper user, and the power supply 23 thereof is preferably a rechargeable battery.

The using method of the paper diaper replacement reminding system comprises the following steps: the person under guardianship wears intelligent paper diaper, and detection device 20 is placed near intelligent paper diaper, does not exceed 20 centimetres, and the guardian wears personal terminal 30. On one hand, the NFC host 21 in the detection device 20 provides a radio frequency field (RF-field) in which the NFC antenna 13 on the diaper is located to perform near field communication with the NFC host 21 to monitor the diaper, and on the other hand, the first short-range wireless communication module 22 in the detection device 20 performs short-range wireless communication with the second short-range wireless communication module 31 in the personal terminal 30 to transmit the reminder signal to the personal terminal 30. When the person under guardianship defecates or urinates, the output of the sensor 11 changes, and after the change signal is detected by the detection device 20, a reminding signal is sent to the personal terminal 30 through the first short-distance wireless communication module 22, so that the purpose of reminding the guardian is achieved. The reminding signal can be sound, vibration, characters and the like. Preferably, set up multiple warning signal, multiple warning signal corresponds the different output value of inductor 11, and like this, the guardian need not go the inspection and can know the humidity of diaper, judges whether need to change the diaper.

By the aforesaid, in this application, do not have bluetooth module, power and controller on the disposable diaper, consequently can effectively reduce the cost of intelligent disposable diaper, thereby effectively reduce the volume of intelligent disposable diaper and reduce the influence to disposable diaper use comfort, also consequently for intelligent disposable diaper is more suitable for commercialization. It should be understood that the sensor of the present application may be a sensor that senses only urine.

The present invention has been described in detail with reference to the specific embodiments, and the detailed description is only for assisting the skilled person in understanding the content of the present invention, and can not be understood as the limitation of the protection scope of the present invention. Various decorations, equivalent changes and the like which are performed on the scheme by the technical personnel in the field under the conception of the invention are all included in the protection scope of the invention.
