Below by the description of drawings several embodiments of the present invention.At first, be diaper adhesional wetting pick off shown in Fig. 1 and Fig. 2.This diaper adhesional wetting pick off 1 adheres to the electrode 3,4 of a pair of separation slightly (apart from d) that is made of metal film on the impervious la m 2 of moisture, being covered with one deck more in the above also is the surface layer 5 that can not see through moisture.
As shown in Figure 2, the lip-deep combined belt 7 that is provided with and is located at diaper 6 on la m 2 carries out bonded combined belt 8.As combined belt 7,8, can on either party's surface, fabric fibre be woven into rope form and make it outstanding, on the opposing party, then form the bossing that is meshed with this rope form ledge.Certainly, other structure also can adopt.9, the 10th, the lead-in wire that is connected with electrode 3,4.
When la m 2 was secured on the surface of diaper 6 under the effect of combined belt 7,8, la m 2 was subjected to the influence of the dielectric constant of diaper 6 one sides, and surface layer 5 then is subjected to the influence of the dielectric constant of air.Represented among Fig. 3 that diaper 6 is dampened, the situation the when dielectric constant of la m 2 one sides has risen to " 80 " under the effect of moisture.At this moment, the dielectric constant in the air of surface layer 5 one sides still is " 1 ", therefore, has just produced very big difference.Therefore static capacity between the electrode 3,4 also changes a lot.
In actual fabrication, obtain in the sample of data, la m 2 and surface layer 5 have adopted plastic sheetings such as following, thick 5～50 microns rectangle polypropylene of wide 40mm, long 80mm, polyester.Electrode has adopted materials such as aluminum, inferior lead, copper, and width is 10～20mm, and thickness is below 50 microns.The distance that electrode is 3,4 is made as about 0.5mm.These two electrodes 3,4 form by modes such as bonding, evaporation deposition or laminations along the length direction of la m 2.The flat shape of electrode 3,4 as shown in Figure 1, its relative edge is the dentation of crouching, but also can make the undaform meander-like, perhaps merely parallelly also can.Make crouch dentation or undaform meander-like, though the adhesional wetting the shape more complicated time also can adapt to well.
An example of the diaper adhesional wetting alarm device that has been to use above-mentioned adhesional wetting detecting sensor 1 shown in Fig. 4.Below this embodiment is described.11 is agitator, and it is added to the AC signal of certain frequency on the electrode 3 of adhesional wetting detecting sensor 1.Owing to have the electrostatic capacitance amount of a constant volume between the electrode 3,4, when AC signal is added on the electrode 3, also can generate voltage on the electrode 4.When load is connected with electrode 4, can flow through in the load and the corresponding electric current of static capacity.Alarm 13 is connected on the electrode 4 by I-V changer 12, detects the variation of static capacity.This signal is supplied to the vibration generator 15 that links to each other with its outfan from the operational amplifier 14 that is connected on the back.
The following describes its effect.As previously mentioned, the combined belt 8 that is located in use on its la m 2 of adhesional wetting detecting sensor 1 bonds on the combined belt 7 on diaper 6 surfaces.Before bonding on the diaper 6, the degree of drying of la m 2 and surface layer 5 sides equates so dielectric constant is about " 1 ", do not have difference to produce.After bonding on the diaper 6, the humidity of la m 2 one sides slightly effectively increases, and dielectric constant slightly changes, and the static capacity between the electrode 3,4 also changes.In addition, when diaper 6 is dampened owing to the drainage of user, the dielectric constant of a side that is dampened will become very high, reach about " 80 ", therefore, just can detect at once in case adhesional wetting takes place.
Like this, the state when pasting on the diaper 6 with an adhesional wetting detecting sensor 1 is a benchmark, and the state when this state constantly is dampened with diaper 6 is compared, and just can catch the static capacity that bigger variation takes place because of adhesional wetting, makes vibration generator 15 work.
Making vibration generator 15 work be applicable to that (for example) drains can't be independently but then oneself can carry out the situations such as old man of processing thereafter as being apprised of drainage.In the time of need notifying the nurse personnel as oneself also carrying out thereafter processing, then connect a buzzer and replace vibration generator 15, perhaps buzzer is connected together with vibration generator 15.
Figure 5 shows that an alternative embodiment of the invention.This circuit comprises: the agitator 16 of the output signal of detector 13 being modulated usefulness; With above-mentioned signal to air-launched emitter 17; Antenna 18; Reception is from the antenna 19 of the electric wave of antenna 18; To the receptor 20 that the electric wave from antenna 19 receives, detection is used; Be used to switch the change-over switch 21 of the output signal of receptor 20; And vibration generator 15 that is connected with change-over switch 21 and buzzer 22.
In this embodiment, when the static capacity between the electrode 3,4 changed because of diaper 6 is dampened, its signal passed to receptor 20 with wave mode, made vibration generator 15 or buzzer 22 work that switch 21 is switched that are switched.When switching to vibration generator 15, the nurse personnel that this vibration generator is worn on one's body are apprised of because of vibration; And when switching to buzzer 22, the nurse personnel stop to sound to get the information, and just can carry out the replacing of diaper 6 at once.
Shown in Figure 6 is another embodiment of the present invention.In this embodiment, have the identification number additional function in the agitator 16, be provided with identification number evaluator 23 in the latter half of receptor 20.The outfan of identification number evaluator 23 is connected on the personal computer 25 as an example of device by communication cable 24.
In this embodiment, owing to can identify concrete people, therefore can monitor a plurality of people's state simultaneously by identification number.That is to say that diaper is dampened the static capacity that makes 3,4 at electrode when changing, and by agitator 16 affix identification numbers, is transmitted in the air with the electric wave form on its signal again.19 pairs of these electric waves of antenna receive, and receptor 20 is input to detection in the identification number evaluator 23, just can learn that whose diaper has been dampened from the picture of personal computer 25 by identification number.
