Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a diaper, and more particularly, to a disposable diaper with a wetness alarm, which immediately issues an alert when a diaper is wet to notify a nurse or a family of the diaper so that the diaper can be changed quickly.

[0002]

[Prior art]

 As shown in FIGS. 12 and 13, a conventional disposable diaper with a moisture alarm has a waterproof layer 101 such as a polyethylene (PE) waterproof material on the outer surface and an inner surface layer 102 such as a nonwoven fabric on the inner surface. Further, it comprises a disposable diaper having an absorbent layer 103 formed between the two, and a moisture alarm. In the wetness alarm, two conductors 20 are installed on the top surface of the waterproof layer 101 of the disposable diaper 10, and the conductors 20 are attached and fixed with glue tape 30 so as not to move. Further, an absorber layer 103 is attached to the top surface of the conductor 20. The two conductors 20 function as a sensor, and have the same length. Their inner ends 201 are brought into contact with the water-absorbing material layer 103, and their outer ends 202 are extended to the front side of the disposable diaper 10 to be connected to the controller. Connect and pinch tight. If the disposable diaper 10 gets wet with urine or stool, the water absorbing material layer 103 gets wet and the two conducting wires 20 are electrically connected to each other, and the controller connected to the outer end 202 becomes ON. The controller may sound an alarm or turn on an indicator light to draw attention of a person nearby and cause the disposable diaper 10 to be changed.

[0003]

[Problems to be solved by the invention]

 However, when manufacturing a conventional disposable diaper with a wet alarm, the tape 30 with glue must be kept stationary by the two flexible wires 20 that are easy to bend. Increase by that much. Further, as shown in FIG. 14, when manufacturing the conventional disposable diaper 10, a large number of continuous semi-finished products of the disposable diaper 10 are produced on a production line, and then the semi-finished products are placed one by one on both left and right ends of the disposable diaper 10. , And the separated location is defined as the front and rear ends of one paper diaper 10. However, the outer ends 202 of the two wires 20 provided beforehand must extend to the front side of the disposable diaper, so when the front end of the semi-finished product is cut, the outer ends 202 of the two wires 20 are waterproof. Since the front edges of the layer 101 and the surface layer 102 coincide with each other, the manufacturer peels off the waterproof layer 101 and the inner side layer 102 a little so that the outer end 202 of the conductor 20 protrudes, and firmly connects the controller. You have to do it, and the job is troublesome.

In addition, in the conventional manufacturing process of disposable diapers, an artificial operation is required to remove the waterproof layer 101 and the inner surface layer 102, so that a completely automatic production operation cannot be performed. In addition, since the two conductive wires 20 are generally elongated copper wires, their contact area is small, and the controller is firmly sandwiched after processing, which makes the production troublesome. In addition, conventional disposable diapers 10 contain a small amount of moisture, about 6% during their manufacture, so that they do not dry too much and do not swell too much for convenience of manufacture. However, after a certain period of time since the conductor 20 is assembled, the conductor 20 receives the moisture and rusts, and the hygiene condition is poor, and the alarm device does not operate due to poor conduction.

[0005] Furthermore, if the conductor 20 is not securely fixed, the user may be pierced. Further, when the disposable diaper 10 is discarded after use, the conductive wire 20 may pollute the environment. Accordingly, an object of the present invention is to provide a disposable diaper having an alarm which gives an alarm by turning on an indicator light or making a sound when the disposable diaper becomes wet with urine fluid.

[0006]

[Means for Solving the Problems]

 According to the disposable diaper of the present invention for solving the above-mentioned problems, a thin paper tape having a metal foil stuck on the front surface and a water-absorbing paper stuck on the back surface is used as two sensors of the controller. Insert the inner end of the flat metal foil-coated paper tape between the waterproof layer and the absorbent layer of the disposable diaper. If the difference between the lengths of the inner ends of these two metal foil tapes is adjusted to be smaller or larger, then depending on the humidity of the diaper, the two metal foil tapes can be quickly and / or slowly made to conduct electricity. Or an alarm can be activated when electricity is available.

[0007] Furthermore, the outer ends of the two metal foil-coated paper tapes are projected to the left or right side of the disposable diaper so that a large number of continuously manufactured disposable diaper semi-finished products cannot be cut off one by one. , Fully automatic production of disposable diapers. In addition, a radio signal transmitter is attached to the controller that activates the indicator light and the alarm that emits a sound, and a reception decoding circuit is added in the alarm, and the alarm is formed independently and the signal coming from the transmitter is output. To be received. Nurses can carry this alarm without having to be with infants or sick people using disposable diapers.

[0008] As described above, the metal foil-coated paper tape of the present invention is flat and flexible, so that the mounting operation is easy, and the end of the tape is similar to the circular conducting wire used in conventional disposable diapers. Since it is not sharp, there is no danger of sticking the user's finger. And since the outer end protrudes to the left or right side of the disposable diaper, it is not cut when cutting many disposable diapers made one after another.

By activating the voiced output unit 424, the disposable diaper 1 can be changed in a timely manner by using a vibration method or music to draw attention of a nearby person. What we want to add here is that if the resistance shown in FIG. 5 is R1 = R2> R3, pulling SW1 toward R3 will perform the above-described normal operation, and pull SW1 toward R2. Then, it can be tested whether the electric circuit is normal or not.

Next, as shown in FIG. 6 and FIG. 7, the electric circuit 42 of the controller and the alarm of the second embodiment is configured such that the electric circuit 42 of the controller 4 includes an enlargement circuit 421 and a transmission circuit 425. Numeral 5 is constituted by connecting a reception decoding circuit 51 and a load 52 in order. The reception decoding circuit 51 receives the signal from the transmission circuit 425, decodes the signal, determines that the signal has come from the electric circuit 42 of the disposable diaper 1, and then activates the load 52. The load 52 may be a voiceless indicator light 521 or a voiced output unit including a music IC 522 and a speaker 523. Further, the alarm 5 has a power indicator 53 connected to its power input end. When using, a family member or nurse of a disposable diaper user such as an infant or a sick person carries the alarm 5 or places it near a work place. When the disposable diaper 1 is moistened with urine and electricity is passed through the two metal foil-coated paper tapes 2, the enlarging circuit 421 activates the transmitting circuit 425 to transmit a preset radio signal. Then, the reception decoding circuit 51 of the alarm 5 receives and decodes the signal, and when it is determined that the signal is transmitted from the electric circuit 42 of the disposable diaper 1, the indicator light 521 of the load 52 or the music IC 522 and the speaker 523 are operated. Cause the attention of family members or nurses.

Next, FIGS. 8 and 9 show an electric circuit of a controller and an alarm device according to a third embodiment. In the third embodiment, one alarm device 5 is combined with a plurality of paper diapers 1. Each electrical circuit 42 of each disposable diaper 1 includes an enlargement circuit 421 and a transmission circuit 425. In addition, an alarm device 5 constituted by sequentially connecting a reception decoding circuit 51, a CPU (central processing unit) 54, and a load 52 is independently configured, and the load 52 includes an indicator 524 such as an LCD and a music IC 522, for example. And a speaker 523. When any one of the plurality of disposable diapers 1 becomes wet, the electric circuit 42 transmits a preset radio signal, and the receiving and decoding circuit 51 of the alarm device 5 receives and decodes the signal, and the CPU 54 Is determined from the electric circuit 42 of the disposable diaper, and the character is displayed on the indicator 524, and the music IC 522 and the speaker 523 are operated to warn the family or nurse. .

Referring to FIGS. 4 and 10, the conductive pins 43 on the back surface of the controller 4 include a sleeve 431, a spring 432, and a contact pin 433. That is, the spring 432 and the contact pin 433 are accommodated in the sleeve 431, and the outer end of the sleeve 431 and the inner end of the contact pin 433 are provided with limit portions 434 and 435 which engage with each other. Pushes the contact pin 433 out due to its elasticity. In this way, the conductive pins 43 come into contact with the metal foil-lined paper tape 2 by appropriately pressing them with some elasticity.

When manufacturing a disposable diaper, as shown in FIGS. 1 and 2, the inner ends 21 of the two metal foil-coated paper tapes 2 are extended between the waterproof layer 11 and the water absorbing material layer 13. , Its length can be increased or decreased according to different needs of the user. If the lengths of the inner ends 21 of the two metal foil-coated paper tapes 2 are not the same, the longer metal foil-coated paper tape is brought into contact with urine absorbed by the water-absorbing material layer 13 first, and the water-absorbing material layer 13 When the amount of urine increases to such an extent that it can be transmitted to the shorter metal foil tape 2, the two metal foil tapes 2 are turned on, that is, turned on, and the controller 4 turns on the indicator light. Or make a sound from the speaker to warn. That is, as the difference between the inner ends of the two metal foil-coated paper tapes 2 is smaller, electricity is conducted even if the amount of urine absorbed by the water-absorbing material layer 13 is small, and the controller 4 operates. Conversely, the controller 4 does not operate unless the amount of urine absorbed by the water-absorbing material layer 13 is larger as the difference between the lengths of the inner ends of the two metal foil-backed tapes 2 is larger.

Also, as shown in FIG. 1 and FIG. 2, if the water-absorbing paper 23 is stuck to the back surface of the metal foil-coated paper tape 2, the urine of the water-absorbing material layer 13 is absorbed and the metal foil-coated paper tape 2 is securely attached. Can be contacted with urine. As described above, this embodiment has the following effects. (1) Since both the metal foil-coated paper tapes 2 are flat, they are easily sandwiched between the waterproof layer 11 and the absorbent layer 13, so that there is no need to attach them with glue tape.

(2) As shown in FIGS. 1 and 11, when cutting semi-finished products of a plurality of continuous paper diapers 1 manufactured on a production line, cut both left and right sides of each paper diaper 1 already formed. In this case, the left and right sides are respectively the front and rear ends of the paper diaper 1. The outer ends of both metal foil-coated paper tapes 2 protrude outward from the left or right side of each diaper 1 and are not cut off. Therefore, there is no need for a conventional artificial operation for separating the waterproof layer and the surface layer of the disposable diaper.

(3) When manufacturing the disposable diaper of the present embodiment, there is no need for an artificial operation, and the disposable diaper can be produced by a fully automatic flow operation, so that the operation efficiency is high. (4) Since both metal foil-coated paper tapes 2 are flat, they have a sufficient area for contact with the conductive pins of the controller 4, and there is no drawback of the conventional work of firmly sandwiching a thin conductive wire having a small contact area with the controller.

(5) Both metal foil-coated paper tapes 2 have no possibility of causing rust in the disposable diaper 1. (6) The two metal foil-coated paper tapes 2 have no problem of piercing the user in the disposable diaper 1. (7) When discarding the disposable diaper 1, the metal foil tape does not pollute the environment.
