Description
i l- ~ \ -1-i l- ~ \ -1-
Inrichting tot het meten van de aanwezigheid van geleidende vloeistoffen,gekenmerkt door het toepassen van minstens twee elektrisch geleidende en vochtdoorlatende elektroden,aangebracht op een vochtabsorberende laag.Device for measuring the presence of conductive liquids, characterized by the use of at least two electrically conductive and moisture-permeable electrodes, applied to a moisture-absorbing layer.
De uitvinding heeft betrekking op een inrichting welke het mogelijk maakt de aanwezigheid van een kleine hoeveelheid vocht,zoals die bijvoorbeeld ontstaat bij een beginnende urine lozing,te meten.Hiertoe worden de geleidende eigen-5 schappen van een vocht absorberende stof,die minstens twee elektroden bevat,gemeten op zodanige wijze dat de uitgangs-spanning of -stroom van een meetschakeling een alarm in werking stelt.The invention relates to a device which makes it possible to measure the presence of a small amount of moisture, such as that which arises, for example, from an incipient urine discharge. To this end, the conductive properties of a moisture-absorbing substance, comprising at least two electrodes measured in such a way that the output voltage or current of a measuring circuit triggers an alarm.
Een voorbeeld van een dergelijke inrichting is de katoenen 10 luier met twee ingenaaide elektrisch geleidende draden welke via drukknopen met een alarm eenheid kunnen worden verbonden.An example of such a device is the cotton diaper with two sewn-in electrically conductive wires which can be connected to an alarm unit via push buttons.
Een nadeel van deze urine alarm luiers is dat de produktie methode zodanig is dat de produktie kosten te hoog zijn om eenmalig gebruik toe te staan.Voor het dientengevolge nood-15 zakelijke herhaalde gebruik dienen deze luiers na elk gebruik gewassen te worden om de zoutresten weg te spoelen,hetgeen de constructie van de elektroden en hun bevestiging aan de drukknopen nauwelijks of in het geheel niet verdraagt.Er bestaat daardoor altijd onzekerheid over de vraag of de elek-20 trische contacten mogelijk onderbroken zijn,hetgeen bij een droge inrichting niet vooraf te testen is.Naast de meetonze-kerheid zijn de hoge kosten van het voortdurend nieuwe luiers aanschaffen een groot nadeel van de huidige inrichting.A drawback of these urine alarm diapers is that the production method is such that the production costs are too high to allow single use. For the consequent necessary repeated use, these diapers must be washed after each use to remove the salt residues which hardly tolerates the construction of the electrodes and their attachment to the snap fasteners, so there is always uncertainty as to whether the electrical contacts may have been interrupted, which cannot be done in advance with a dry device. In addition to the measurement uncertainty, the high cost of constantly purchasing new diapers is a major drawback of the current device.
De uitvinding heeft tot doel een inrichting van de in de 25 aanhef genoemde soort te verschaffen die dermate eenvoudig en goedkoop te maken is dat de inrichting als wegwerp produkt voor eenmalig gebruik geschikt is.Tevens voorziet de uitvinding in een mogelijkheid de werking voor of tijdens het gebruik te testen.The object of the invention is to provide a device of the type mentioned in the preamble, which is so simple and inexpensive to make that the device is suitable as a disposable product for single use. The invention also provides an opportunity for operation before or during use.
30 De inrichting volgens de uitvinding heeft daartoe het kenmerk dat de elektroden eenvoudig aan weerszijden van vocht absorberend materiaal,zoals papier,textielvezel enz.zijn aan te brengen en via een knijpcontact met de alarm eenheid kunnen worden verbonden.To this end, the device according to the invention is characterized in that the electrodes can easily be arranged on either side of moisture-absorbing material, such as paper, textile fiber, etc. and can be connected to the alarm unit via a pinch contact.
8203901 -2-8203901 -2-
Een voorkeurs uitvoering van de inrichting volgens de uitvinding zal nader worden toegelicht aan de hand van Figuur 1.A preferred embodiment of the device according to the invention will be further elucidated with reference to Figure 1.
De in Figuur 1 afgebeelde inrichting bevat een vocht absorberende laag l.Aan weerszijden van laag 1 bevinden zich 5 elektrisch geleidende lagen 2 welke vocht doorlatend zijn, door ze bijvoorbeeld als raster of in banen uit te voeren.Bij voorkeur bestaan deze elektroden uit een metaal of koolstof bevattende verf of inkt,direct aangebracht op laag 1 via een daartoe geëigende techniek,dan wel op een apart vocht doorla-10 tend dragermateriaal dat naderhand op laag 1 wordt bevestigd. De elektrode configuraties kunnen al of niet worden afgedekt met een vocht doorlatende beschermlaag 3 onder uitsparing van contact gaten 4 voor het aanbrengen van bijvoorbeeld een knijpcontact waarmee elektrisch contact wordt gemaakt met 15 elektroden 2.The device shown in Figure 1 contains a moisture-absorbing layer 1. On either side of layer 1 there are 5 electrically conductive layers 2, which are moisture-permeable, for example by designing them as a grid or in strips. These electrodes preferably consist of a metal or carbon-containing paint or ink, applied directly to layer 1 via an appropriate technique, or to a separate moisture-permeable carrier material which is subsequently attached to layer 1. The electrode configurations may or may not be covered with a moisture-permeable protective layer 3 under the recess of contact holes 4 for the provision of, for example, a pinch contact with which electrical contact is made with 15 electrodes 2.
De inrichting maakt het mogelijk dat de meting van elektrische geleiding tengevolge van binnendringend vocht geschiedt onafhankelijk van de plaats waar een minimale hoeveelheid vocht de inrichting binnendringt.The device allows the measurement of electrical conductivity due to moisture penetration to take place regardless of where a minimal amount of moisture enters the device.
20 De inrichting kan,indien gewenst,op de werking worden getest door met de vingers de blootliggende delen van de elektroden naast het knijpcontact aan te raken,dan wel op een willekeurige andere plaats waar een uitsparing in de beschermlaag 3 is aangebracht.De elektrische geleiding van het mense-25 lijk lichaam vervangt dan tijdelijk de interne elektrische geleiding van de inrichting die optreedt indien vocht de inrichting binnendringt.If desired, the device can be tested for function by touching the exposed parts of the electrodes next to the pinch contact with your fingers, or at any other place where a recess is made in the protective layer 3. The electrical conductivity of the human body then temporarily replaces the internal electrical conductivity of the device which occurs when moisture enters the device.
Het zal duidelijk zijn dat de beschreven inrichting in elke gewenste dimensie kan worden vervaardigd en vervolgens al of 30 niet in kleinere eenheden is te scheiden.It will be clear that the described device can be manufactured in any desired dimension and then may or may not be separated into smaller units.
De in Figuur 1 weergegeven inrichting is slechts een voorbeeld en kan op vele punten gewijzigd worden.De elektroden kunnen ook aan één zijde worden aangebracht via patronen die over het oppervlak verdeeld zijn.Ook het maken van elektrisch 35 contact met de elektroden kan op andere dan de aangegeven wijze geschieden.De contacten kunnen tevens de aan/uit functie van de meetschakeling bevatten.The device shown in Figure 1 is only an example and can be modified in many ways. The electrodes can also be applied on one side by patterns distributed over the surface. Electrical contact with the electrodes can also be made by means other than the indicated manner. The contacts can also contain the on / off function of the measuring circuit.
Door het toepassen van meerdere elektroden of elektroden met een resistief karakter kan met de inrichting volgens de 82 0 3 § 01 -3- » uitvinding ook de plaats van een lokale vocht indringing worden bepaald.By using several electrodes or electrodes with a resistive character, the device according to the invention can also determine the location of a local moisture penetration.
Bij toepassing als wegwerp luier kan een hechtstrip worden toegevoegd ter bevestiging van de inrichting aan het 5 ondergoed.When used as a disposable diaper, an adhesive strip can be added to attach the device to the underwear.
