Description

Disposable Diapper with Adherent Alarm Many types of diappers with different designs and functions exist in the actual market. However, after a survey, we may notice that much emphasis is put on the quality and design of the product in order to increase its hygienic effects. For example: high absor^fency, comfort and convenience .... etc . Since mass production reduces the cost of the product, people put even more emphasis on the disposability of the diappers in consumer market. Generally we dispose the used diapper by enrapping it with the already incorporated adhesive tape, thus cleanly disposed. To use diappers means to bring convenience to users, but not to increase thier discomfort when the diappers are not changed on time. For this reason, the users must be under continuous care and attention so that the wet diappers can be changed constantly, avoiding discomfort and infections due to the excels. It is a tough and tiresome job for those who take care of babies and patients. They must check it constantly by moving away blanket, taking off pants, then check the diapper by touching, smelling or removing the diapper, For both users and persons who take care of them, this is an annoying process, especially for those professional nurses who work in hospitals or asylums, because they have many babies, patients and aged people under thier responsibility.

Summary of the Invention This invention provides a new structural design of the -1/)IE 904355 diapper with adherent alarm. Both can be joint to together and separated easily. The alarm detects the humidity and produces a warning sound which can be heard clearly.

Brief Description of the Invention FIG 1 is a perspective view of this invention in a normal position .

FIG 2 is a side view of this invention in vertical cut position.

FIG 3 is a diagram of printed circuit incorporated in the diapper.

FIG 4 is a perspective view of the alarm in vertical position.

FIG 5 is a top view of printed sensory lines.

Description of the Preferred Embodiment As shown in FIG 1, this invention consists of two major parts: a diapper and an alarm. In the outside layer of the diapper there are two appropriate pockets(ll), one in front and the other in the back. When the user lies on the back we put the alarm in the front pocket, and viceversa. In other words, the lying position of the user does not affect the effectiveness of this invention. The alarm can be clipped conveniently in both ways, depending on the users’ need. The shape of the alarm(2) is like a shell in proper size with battery power supply, IC, IC board, speaker and other electronic parts. On the shell, there is a hole for sound output which matches the pockets(ll) of the diapper(l). Since the pocket(11) of the diapper has the same -2IE 904355 size as the alarm(2), this can be easily put into the pocket without any contact to the skin. Besides, the alarm can be designed with spring clip (as shown in FIG 2). It is easy to get the alarm fixed firmly. Those who take care of babies or patients can carry out their duty only by paying attention to the alarm.

This will ease a lot their working pressure. Another design is considered in thin, round and smooth shape. It makes the user more comfortable when the alarm is used. The sound output hole (21) of the alarm(2) has its face out. Since the warning sound will not be absorbed by the diapper, the sound effect will be better and be clearly heard. The alarm fits the size of the pockets(ll) of the diapper(l), and the clips meet the conductors (12) at the ends of sensory lines(13). These conductors can be designed in a larger size in order to keep in touch well with alarm clips(2). The two sensory lines(13) are in the inside layer(14) of the diapper (as shown in FIG 2). When the inside layer(14) absorbs certain humidity, it makes the two sensory lines in active condition. As shown in FIG 4, the alarm(2) with its electronic components and clips(22), conductors (12) and sensory lines(13) form an active electronic circuit and then make the alarm sound like agreeable music. Because of the humidity of the diapper, the music sounds continuously, informing the nurse to come to change it, until the alarm is removed.

After analyzing the production cost and technology, this invention, including alarm(2) and the diapper itself is a feasible one, because we may keep the alarm and reuse it repeatedly. -3IE 904355 Though we dispose the diapper after using it, we also put emphasis on its unit cost. Under keeping its original functions, the production cost and technology of the conductors and sensory lines can be reduced, and the design can be changed or simplified. As shown in FIG 5, the sensory lines(13) are printed on a thin paper with conductive materials (like carbon, silver glue .... etc .). At the same time, the ends of the sensory lines can be enlarged and used as conductors. Nowadays, the technology of printed ciecuit is widely used in electronic industries, there is no problem in any process of production of this invention. We can produce it in a large scale and high efficient way in order to reduce the production cost. Furthermore, the ordinary diapper generally has isolated paper between inside layers, the sensory lines(13) can be printed on the same paper. It does not affect the function of the diapper. The sensory lines(13) can be parallal or curved ones.

The distance between two sensory lines(13) in the middle part can be widen, through special design to get different sound effects and avoid the alarm sounding in low humidity condition.

The main purpose of this invention is to provide a new design and structure of disposable diapper with adherent alarm. In fact, they are used together but they can be easily separated. The consumer may dispose the used diapper and keep the alarm for reuse repeatedly. It is very economic and practical. Another purpose is to provide a simple sensory structure between the alarm and the diapper. Each pocket on the diapper has two pieces of conductor which are linked to sensory lines. When the alarm is attached to the pocket, they form an electronic circuit. While the sensory -4IE 904355 -5lines get wet in the same time, they are in active condition and make the alarm sound. Even more, the alarm can be attached to either pockets of the diapper according to the users’ need. It lets the alarm sound better and get more effects.

Claims (4)
