Description

DESCRIPTION

ABSORBING SANITARY ARTICLE WITH A SIGNALING DEVICE

*****************************

The present invention refers to an article or product made-up of one or more layers of material permeable to liquids, especialy for personal use as an absorbing means of organic liquids, applied on the interested part to be checked.

The drawbacks found in the use of normal absorbing sanitary towels used in the hygiene and/or protection of intimate parts, specificaly for new-born babies are well known.

The new-born babies cannot notify to their parents or the person taking care of them for the loss urine and/or solid evacuation usually associated to the emission of urines.

Therefore, they remain wet with all unconfort caused by the irritation, reddening, etc. of the skin, up to the moment the napkin is changed.

The same drawbacks occur in the elderly people, disabled or suffering due to incontinence and generally no more self-sufficient, both assisted in their own home or in nursing homes, charitable institutions, etc.

On the other hand, the operation of change of napkin, of any dimension, causes a certain time of loss for the people who take care of them because they are compelled to make repeated inspections of their underwear till they verify the wet condition of the napkin and then make its replacement. It is also well known that the use of normal towels, tampons, etc., causes particular unconfort for women during the menstruation period. In fact, during the menstruation cycle, they feel the need of knowing if the leaks have started or in course or ended. For this aim, they are compelled to verify visually their condition and this can often be a cause of disconfort due to unsuitable place or in the presence of unfamiliar persons, etc.

Furthermore, during the nursing women feel the .necessity of knowing the moment of maximum milk production, and this situation actually is noticed only after the soaking of the brassiere when milk outlet has already occurred.

An object of the present invention is to provide a new item or absorbing article, especially a napkin, large napkin, mattress (or uπderblanket) for the bed, tampon, panties, brassiere and similars which eliminate all above mentioned drawbacks and that also allow to extend its use for animal organisms.

In accordance with the present invention, the above mentioned and other objects are fulfilled by an article made of absorbing material including at least a couple of electrical conductive elements or electrodes inserted in the material mass and connected with at least a couple of external terminals which can be connected with electric means suitable to: a) provide an electric potential difference between said conductive elements for all the time in which the material interposed between the above elements remains dry (open circuit) and, besides b) causing a current passage between said conductive elements and simultaneously the activation of signaling devices as soon as the material interposed in between is impregnated with liquid (closed circuit) .

Therefore, the article according to the invention works as an automatic detector of the liquid presence, so that, in the particular use of the new-born baby or elderly person, the caretaker can operate at once when it occurs the loss of urines, etc. and it is thanks to the activation of the signaling circuit, so obtaining a double advantage because immediatelly alleviates the baby or the patient from the unconfort of the wet and eliminates for any time loss due to casual inspections.

The advantage is particularly evident in the case of new-born babies in pediatric hospitals or elderly persons in geriatric homes, where the plurality of assisted persons can be kept under continuous survey by the sanitary operators located at distance in an only checking place.

Further advantages and characteristics of the absorbing article shall be clearly understood by the following description referred to the annexed drawings which, are only for an example with unlimitative aims, show some embodiments of the article made according to the invention. In the drawings:

Fig. 1 shows, in vertical section and in a schematic manner, a generical article associated to an electric feeding and signaling apparatus, according to the invention;

Fig. 2, 3, 4 and 5 show some embodiments of the conductive elements embodied in the article;

Fig. 6 shows an absorbing towel before its use, embodying the conductive elements; and

Fig. 7 shows also an absorbing towel coupled with an electric transmission and reception apparatus for the signals caused by the liquid presence in the towel .

With reference to Fig. 1, it is shown by reference letters MA an absorbing article in which a couple of electric leads or electrodes CI, C2 are enbodied and by reference letters ME some electric means coupled to the article and which are able to feed the above mentioned leads, as it shall be explained in the following."

The article is made-up, in the well-known manner, by one or more layers or material mass permeable to liquids and of absorbing type as e.g. felt.

The inside of the article at least a couple of electric leads CI and C2 is inserted and located in spaced and faced position, said leads showing at least an external couple of electric terminals 1 and 2.

The shape and dimensions of the leads, their distance, location and configuration, and their path in the inside of the article as well as the shape and thickness of layer or layers of materials forming the article can widely vary in connection to the particular use of the article. So, they can assume a simple shape of wires or strap elements with linear or winding development or with other shapes, as described in the following, but suitable always to form at least a couple of conductive elements.

The Fig. 2 shows in perspective view the couple of conductive elements CIA and C2A and the intermediate layer of the article. Each conductive element can be made in the shape of metallic grate that can be previously wrapped in an absorbing sheet, before being assembled in the material layer.

The Fig. 3 and 4 show the couple of conductive elements C1B, C2B and C1C,

C2C extend on a plane with a sinusoidal or greek feet path, respectively. In this case, it shall be a single plate wrapped in an absorbing sheet to be assembled in the article material.

Finally, Fig. 5 shows each element of the couple of leads C1D and C2D made by a plurality of elementary leads located in parallel such as a comb and the two pluralities of elementary leads are coupled in opposed position so that the elementary leads are offset with one another.

Refering again to Fig. l,""the electric means ME include substantially a suitable feeding source SA as a battery, a cell, etc. and a signaling device DS of the acoustic type such as a bell, buzzer and/or of luminous type such as a pilot lamp or, in general, formed by any electric/electronic apparatus such as a -radio, television, interphone, telephone, etc..

The source SA and the device DS can form a single unit directly put on the article or located at a certain distance. In any case, the electric connection on the source with the article occurs only at the moment of use. As an alternative, the feeding source and the signaling device can form two separated components, the first one, for instance a feeding cell, included in the article and to be connected to the article at the moment of use, and the second one, the signaling device, installed at distance in a checking place.

In the latter case the electric connection with the signaling device can be made by means of a cable or through air as shown in Fig. 7, where the article is made up of the absorbing napkin PA shown better in Fig. 6 and the transmission of the signal occurs by the help of an emitting apparatus E located in the starting station and of a receiver apparatus R located at a distance in the checking station, nearby the signaling device DS. With reference to Figure 1, the operation of the system is as follows:

During the use, the feeding terminals 3 and 4 of the source SA are connected to the input terminals 1, 2 of the leads couple CI, C2 so that it cause an electric potential difference between said leads. However, for the all time in which the material inserted between the leads remains dry and works accordingly as an insulant material, such potential difference does not cause any current passage "as the leads and the feeding source form an open circuit. Certainly, in this condition the signaling device DS is not operating.

Otherwise when the article is impregnated or wetted with liquid suitable to supply electric characteristics to the material layer interposed between leads, then the closing of the above mentioned circuit occurs, therefore causing the current to flow through the feeding source SA and the electric leads CI and C2.

Simultaneously at the current flow in the above mentioned circuit, it is automatically activated the signaling device DS which signals the presence of liquid in the article.

In this way, the wet condition of the article is signaled and the caretaker can immediately make its replacement or in any case be aware of this situation.

In the case of liquids not having suitable characteristics of electric conduction, a previously treated material to supply conduction characteristics to the liquid with which it come in touch with or suitable to increase such characteristics, it could be used at least for the layer of the article which separates or wraps the leads. An article as napkin, large towel or absorbing underblanket is especially foreseen for the use as automatic detector of urine losses of babies, incontinent persons, longstay infirm, disable persons and in any case not self-sufficient persons.

The signaling device used in the case of babies could also emit a fantasy music to quieten and amuse the baby and furthermore to notify to the sanitary operator that the liquid emission has occurred. In this application, it can be foreseen, a signaling system which is not immediately operating when the napkin is wet (for istance as not to waken the baby) , but when it is needed to verify his status; in this situation the signaling circuit should be supplied with suitable device (pushbutton, lever, switch, etc.) to allow the selection between the two operating possibilities (in a continuous manner or under control) . *

If the patient is assisted in pediatric or geriatric hospitals it is advantageous to connect the plurality of towels applied on the interested part of patients to a single signaling apparatus located in an unique checking place, so that the survey of the assisted persons entrusted to a few operators who will operate on single persons only after the signaling of urine loss.

Furthermore, the article can be used as menstruation detector or milk losses detector in the puerpera and further as gloves humidity or wetting detector or in other articles used for the infancy. Of course, in the case of article used by women, the signaling shall be of a discreet type. The articles can be also used as a sort of a cap, as detector of milk losses by the animals such as cows and general as detector for the presence of liquids in other uses which are not mentioned here.

Of course, it is possible to change the number of leads, the reciprocal distance and other characteristics of components in order to regulate the intervention sensibility of the system.

For example, this sensibility could be adjusted acting on the wetting

"threshold" sufficient to activate the device, linked to the variation of the electric resistance between the two electrodes which is very high in the case of a dry towel and decreases in presence of organic liquids.

The threshold could be adjusted either during manufacturing phase in the different models of towel or by the operator at the moment of use of the article by proper device.

It could be underlined that the evident utility of the detector does not influence the product price in a significant manner.

The feeding and signaling system, both of local and remote type, does not require specific maintenance. Its duration can be estimated in ab. 2-3 months, and after with the replacement of some components, for instance the battery, the system can again be used.

As absorbing towel, especially for the babies, the article is a product of wide use and therefore it can be supplied also in great storehouses, supermarkets, etc..

The person who is interested can foresee a provision of towels of which each including only the lead couple with external terminals and, at the moment of the use, after having applied it to the interested part to be checked, activate the towel through the connection of the terminals to a simple feeding and signaling device. In the foregoing specification and drawings specific examples have been used to illustrate the invention. However, it is understood by those skilled in the art that certain modifications can be made to these embodiments without departing from the spirit and scope of the invention.

It can be forseen, accordingly to a further aspect of the invention, an internal electromotive force source instead of the external energy source SA i.e. a self-feeding system which exploits the electrochemical characteristics of the organic liquids.

In this case, the terminals 1 and 2 will be used only for the connection with signaling circuit.

Finally, owing to the low cost of the article, it can be hypothesized a solution of the type "wear and scrap". This may be done in relation to the fact that the device is made-up of a part to be rejected (electrodes and terminals) embodied in the material and a part to be used again (feeding devices, if needed, and signaling devices) provided with pushbutton to be applied to the towel only at the moment of use and to be removed at the moment of change of towel.
