Description

Device for detecting and signaling the presence of urine in a

diaper

  The present invention relates to a device for detecting

  ter and report a wet condition in a diaper so that a

  caregiver can be alerted and change the diaper

  pants of the wearer of the diaper.

  Diapers are used to prevent the urine of a baby or an adult with medical problems from soiling the bed, clothes, etc. However, when medical personnel are unaware that the diaper has been contaminated with urine and

  baby's or patient's stool and does not change the diaper, baby

  or the patient may have a very unpleasant feeling. Therefore

  As a result, the wearer of this wet diaper can develop a rash at the diaper and catch a cold in cold weather. As the evacuation of stool is always accompanied

  urine, a device that is capable of detecting urine in a cou-

  panty is also able to detect the fact that the wearer has

  urinated and defecated. When a caregiver is fast-

  warned that the wearer of the diaper has urinated or

  he or she can replace the soiled diaper with a diaper

  dry and clean pants to prevent the wearer from developing

rash or catch a cold.

  An object of the present invention is to provide a device

  tif used to detect and report the presence of urine in a diaper-

  panties so that a caregiver can be alerted to change the diaper of the diaper wearer in time for the skin of the diaper wearer to remain

clean and dry.

  Another object of the present invention is to provide a device for detecting and signaling the presence of urine for use in hospital nurseries so that the nurse can quickly determine which diaper wearer has need

to be changed.

  The device used to detect and report the presence of uri-

  ne in a diaper of the present invention comprises an organ-

  no detector housed in an absorbent material in the middle of the layer-

  cheeky. The detector member is electrically connected to conductive elements connected to a housing which contains an amplifier circuit, a battery and a signaling device; the housing is fixed so

  detachable from the diaper so that it can be removed from a diaper

  soiled pants to replace them on a clean diaper

  when the wearer of the diaper urinates.

  When the wearer of the diaper fitted with the urine detection and signaling device, the detector body can detect

  wet condition in the diaper, and activate the amplification circuit

  tor. The amplifier circuit then activates the signaling device

  in order to alert a member of the nursing staff; the signaling device

  reading can be a light bulb or a musical integrated circuit

  paired with a speaker, or both.

  A device for detecting and reporting urine according to the

  present invention for use in a hospital dormitory

  takes radio transmitters, each one connected to a detector

  respective diapers, and a portable alarm system that in-

  clut an amplifier circuit, a signaling device, a transco-

  deur, a central unit, and a radio receiver so that when one of the diapers is in a wet state, the alarm system can alert the caregiver wearing the same system to change the wet diaper , the radio receiver receiving a message from the radio transmitter, that the transcoder and the unit

  central have to deal with; the central unit activating the signaling device

  reading in order to emit light or sound. The signaling device

  can be a liquid crystal display and an integrated circuit

  music associated with a loudspeaker in order to display the color numbers

  matching panties, so that the staff member is

  Gnant knows which diaper needs to be changed.

  The present invention will be better understood on reading the

  following detailed description, with reference to the accompanying drawings

in which:

  FIG. 1 is a view of a detection and detection device

  generalization of the presence of urine attached to a diaper according to the pre-

  invention; FIG. 2 is an electrical diagram of the device for detecting and signaling the presence of urine of the present invention; Figure 3 is another view of the device for detecting and signaling the presence of urine attached to a diaper according to the present invention; Figure 4 is an enlarged fragmentary view of Figure 3 and the associated part; Figure 5 is an electrical diagram of the detection device

  and signaling of the presence of urine, the signaling device of which

  tion is portable according to the present invention; and Figure 6 is an electrical diagram of the detection device

  and signaling of the presence of urine, the signaling device of which

  tion is portable, and is associated with several detector bodies fixed on

respective diapers.

  Referring to Figures 1, 2 and 3, a detection device

  and signaling for the presence of urine of the present invention

  takes a detector 2, a battery 3, an amplifier circuit 4 and

  a signaling device 5; the detector member 2 is fixed to a ma-

  absorbent material 11 in the middle of a diaper 1; conduc-

  tors 21 are connected by one of their ends to the detecting member

  author 2; the other end of the wires 21 is associated with conductive pads

  22, which are attached to an upper end portion of the

  diaper 1, preferably the size of diaper 1

  shown in Figure 3. A contact closure 12 of the Velcro type is attached to the diaper around the conductive pads 22 without

  cover the conductive pads 22.

  The battery 3, the amplifier circuit 4 and the signaling device

  sation 5 are placed in a box 6. We can refer to the figure

  2 which shows the electrical diagram of the parts inside the housing 6.

  The amplifier 4 is electrically connected to the battery 3 and to the signaling device 5. The battery 3 is equipped with a light bulb

  31 indicating the power supply voltage. The si-

  generalization 5 is a light bulb 51 or a musical integrated circuit

  cal 52 associated with a speaker 53 or an audible warning.

  The housing 6 comprises two conductive elements 32, 41 fixed to the outside as shown in FIG. 4. A contact closure 61

  Velcro type) is attached to the outside of the housing without covering the

  conductive elements 32, 41. The housing 6 is mounted in a detachable manner

  ble on the diaper 1, the conductive elements 32, 41 being connected to a respective patch 22, 22 by the contact closures

12, 61.

  When a wearer of the diaper fitted with the device

  urine detection and reporting system of this information

  urine or defecate, the detector organ 2, detecting a humi

  of in the diaper 1, activates the amplifier circuit 4 in order to

  activate the signaling device 5. If the signaling device 5 is a light bulb 51, the nursing staff will be alerted by the light from the bulb 51 of the need to change the diaper 1. If the signaling device 5 is a musical integrated circuit 52 associated with a loudspeaker 53, the nursing staff will be alerted by the

  music or the sound emitted by the speaker 53. The signaling device

  station 5 may also include the light bulb 51 and the musical integrated circuit 52 associated with the loudspeaker 53 so that the personnel

  caregiver can be alerted both by sound and visually.

  With reference to FIG. 5, a radio transmitter 54 is connected to the amplifier circuit 4. An alarm system 7 is intended to be worn by the nursing staff. The alarm system 7 includes a

  battery, radio receiver 71, transcoder 72, and signaling device

  generalization 73; the signaling device 73 may be a bulb

  luminous 731 or a musical integrated circuit 732 associated with a loudspeaker

  their 733 or both. A 741 light bulb indicating the voltage

  power supply is connected to an input of the power supply

  plate 74 used for the alarm device 7. The transcoder 72 translates the

  message received by the radio receiver 71, and, confirming that the message

  ge comes from radio transmitter 54, activates the signaling device

  73 in order to alert the nursing staff.

  In Figure 6 is shown an electrical diagram of a third-

  me embodiment of a device for detecting and signaling the presence of urine of the present invention. An alarm system 7

  comprises a central unit 75 connected to the transcoder 72 and to the

  73 positive signaling. The signaling device 73 may be a liquid crystal display 734 associated with the musical integrated circuit 732 and the speaker 733 above. Alarm system 7 is used in a hospital dorm where many babies or people

  having medical problems wear their respective diapers

  ves with the aforementioned detector unit 2 and radio transmitter.

  When one of these diaper carriers urinates or defecates, the corresponding radio transmitter transmits a message to the radio receiver 71 of the alarm system 7 that the transcoder 72 must translate. Unity

  control unit 75 then activates the signaling device 73 for my

  determine which diaper needs to be changed based on data from transcoder 72. When a caregiver sees the signal on the LCD, he or she can change

  the diaper in time for that diaper wearer.

  From the description which has just been made, we can understand

  dre that the device for detecting and signaling the presence of uri-

  ne of the present invention has the following advantages: - when the wearer of the diaper fitted with the device for detecting and signaling the presence of urine, urine or defecation, a member of the nursing staff can be quickly notified and can replace the diaper -panty on time; - Velcro type contact closure elements attached to the diaper and to the signaling device housing help the conductive elements of the housing to easily connect the pads

  conductive to the diaper. Therefore, the above-mentioned device

  The present invention can be very easily removed from a soiled diaper and attached to a clean diaper;

  - a member of the nursing staff can carry the system with him-

  alarm 7 and can therefore be warned that a person carrying

  panties urine, even if a certain distance separates it from the wearer

diaper.
