DE2948768A1 - Incontinence pants incorporating acoustic bed wetting alarm - with moisture detected by bridging of conductor wires or foil strips - Google Patents

Abstract

The pants are worn both at night and during the day and incorporate electronic components coupled to contact sources for providing an acoustic alarm signal when even a small amount of urine is released. Pref. the contact sources are formed as foil strips or wires applied to a front flap of the pants. They are covered by a removable absorbent insert which may be washable or disposable. The fastening for the pants incorporates a rubber magnet cooperating with a reed switch to close the current circuit for the alarm device, which is operated when the insert becomes wet allowing a current to bridge the wires of foil strips. The pants are designed to allow greater freedom of movement both in and out of bed and to allow the wearer to reach the lavatory in time.

Description

A v o rw a r n g e r a u p e s g e n g e n t o u t n u s e s

The invention relates to an advance warning device, which is in protective pants integrated, the so-called bed-wetting at night and also during the day through acoustic Signal warns of uncontrolled urine output.

So far, two different types of electronic device are known. Both consist of bed mats, which are criss-crossed with metal wires and the Bed-wetting or the supervisor in the case of urine output via a separate, with the mat through Cable connected device, give an acoustic signal. If the mat is wet, it must a second, third, etc. available as a replacement scin, the mats are very expensive in of manufacture and can only be used when the bed-wetter is lying down. - For hygienic reasons, they have to be washed many times, which is a quick one Wear and tear favors.

In addition, the user can only change the position in the area of the Matte dtjrchf1jl # ren. The cable routing prevents uncontrolled movements in the loop it is easily possible that the signal transmitter by dropping or pulling it out of the cable is disabled.

The signal transmitter of the second device type must be on the bed-wetting body be fastened with a belt-like carrier.

A cable leads to the bed mat, so that the mobility is strong is affected. Furthermore, the relatively large signal transmitter, which is on the body is very uncomfortable for the user. Also, the filing (unplugging) of the device when necessary, that is, especially when the user is in a hurry Having to go to the toilet takes time.

Against both types of devices on the market speaks that the Bedwettingers have to sleep with their lower body bare, otherwise the first urine drainage is sucked up by the clothing and the detector comes into operation too late.

This has the disadvantage that the surrounding bed linen, e.g. Upper bed can be wetted with.

The object of this invention is to provide a warning device for bed-wetting create, which eliminates the disadvantages described so far, which also within a very short period of time gives the user an acoustic warning when a tiny Lots of urine drains. This new device also has the task of providing the user with the greatest possible To leave freedom of movement, i.e.

to move freely in bed or during the day outside of it. Another object of this invention is to make the insert hygienic for single use, E.g. as a disposable item.

The task at hand is solved by something similar to diaper pants designed, light and shrill protective pants to be put on or taken off, which are preferably consists of iiäßeabweisendem, easy-to-care-for material and as a carrier of a Insert is used. Under this absorbent pad there is a contact media carrier, which is provided with moisture-sensitive, conductive film or cable and reacts to the smallest amounts of liquid. renewed even with frequent use. You can also use the contact media carrier, for example be placed.

The signal transmitter is made in a micro-circuit, whereby a very flat, small design is possible. A serves as an on and off switch lleed contact, which closes the circuit by means of a magnet, i.e. by applying it the pants, the circuit is closed, the device is ready for use by Open of the trouser fastener, the device switches off automatically.

The big advantages of this new type of device are: A.) All functionally necessary - Even electronic components are in a comfortable to wear protective trousers without annoying exposed cables housed.

B.) The device is switched on and off by putting it on and taking it off the trousers in a simple, uncomplicated and fast way.

C.) The signal generator, which already when a minimal amount of urine is given comes into operation, emits a continuous warning tone when the III ase dcs Bt-rautztrs lloCll is almost full due to continuous use of the pre-warning device Reflex, which can lead to the healing of the bed-wetter.

D.) Greatest hygiene is guaranteed through the use of inexpensive Disposable absorbent pads that can be quickly and easily replaced after moistening can. The production of these inlays is, for example, in roll form as yard goods with considerably lower costs than those of conventional, textile bed linings. In addition, a roll or multiple pack ensures that enough Insert, even with very frequent use and everywhere, are in stock.

Further details of this invention are explained using an example and provide additional clarifications from the description and the drawings namely show: FIG. 1: The embodiment of an advance warning device against bedwetting in protective pants form in a supervision.

F i g u r 2: The embodiment in a cross section along the Line II - II F i g u r 3: The device in the closed state in a supervision.

F i g u r 4: The block diagram of the device.

FIGS. 1 and 2 show protective trousers in a top view and in section 1 with foldable contact media carrier 2. The exchangeable absorbent pad 3 is around the contact media carrier 2 with the contact wires 4, 5, which are, for example, wave-shaped Applied in any number and spacing, e.g. glued, welded, vapor-deposited are placed and fastened to the inside of the protective pants 1 by means of a push button 6. About two separate contacts 7,8, which are designed as push buttons, is the signal transmitter 9 attached to the front of the protective pants 1 and connected.

By closing the protective trousers 1, e.g. by means of Velcro tape 10 a permanently incorporated Ilart rubber magnet 11 to close the circuit a reed switch 12 is actuated. Even with slight moistening of the absorbent pad 3 the circuit between the contact wires 4,5 is closed and sets the multivibrator 13 of the signal transmitter 9 in oscillation, through which an amplifier stage 14 of the Loudspeaker 15 emits a continuous acoustic signal. The recesses 16 in the contact media carrier 2 allow the urine to drain into the underlying layer of the absorbent pad 3.

A battery 17 serves as the energy source for the device.

FIG. 3 shows the protective pants 1 in the closed state FIG u r 4 is a block diagram of the complete device.
