The document summarizes two ideas for improving diaper designs: 1) A diaper with a wireless temperature sensor that detects a temperature increase to alert caregivers when a diaper is wet, avoiding false alarms. 2) A disposable personal toilet for bedridden individuals that uses suction to extract urine from an absorbent diaper via a flexible hose when triggered by the temperature sensor, collecting it for measurement and disposal. The system is designed to provide independence, hygiene, and ease of use compared to traditional diapers.

2. The future of sensing devices
FIRST IDEA:
Wireless temperature Sensor

3. In Japan? Maybe, they like to change lots of diapers each day.
In Developing or Emerging Countries? For sure not!
Why so many parents were a bit angry in social forums?
In my opinion: It is much better to use it for adult care.
Launched commercially in Brazil in May 2013
Huggies Pee Tweet R
Good concept, but it can be improved
It uses a humidity sensor (not the best )
First some background
before I show you our
first idea

4. Problems with Humidity Sensors
 Premature alarms may tweet when diaper is still almost dry (excessive changes).
 Impossible to reset the alarm for a new insult to maximize diaper`s use.
 A larger baby may be able to remove it by hand, potential liability issues.
 Another problem may be the presence of magnetism near baby`s genitals.
 Magnetism near genitals has been linked to testicular tumors, but only on babies.
 The reality today: Pee Tweet R is not the huge success that was expected! Why?
 What is the real solution? Use a new alert alarm, but preferable only for adult
briefs (for the bedridden and wheelchair patients)

5. Our Solution:
Diaper with Temperature Sensor
Alarm Triggered by a Temperature Pulse
 Diaper uses a reusable temperature sensor outside of the diaper`s Textile Backsheet.
 It can be wireless (like an active RFID), wired, or with an internal tweeting capability.
 External sensor monitors diaper backsheet temperature (without any contact with urine).
 Extremely sensitive sensors already available, within 0.75 C.
 Programmable temperature ramp (pulse)
 Alarm is triggered when the sensor detects a temperature gradient up (an incremental pulse).
 No more premature or false alerts! You can decide how much volume you want to hold.
 It can alert of multiple insults as desired by caregiver.
 If you want a new Tweet or Alarm, you simply reset the alarm and it will be ready.

Battery operated
Miniature RFID (active)
Temperature sensors
Micro wireless
temperature sensor

7. How does it work?

8. The diaper gets an insult. It will
not trigger a signal until it reaches
the wireless temperature sensor

9. The temperature gradient is
detected by the temperature
sensor (works as well if it is
wired without the need of a
battery) and it sends a signal,
sound alarm or tweet.

10. The caregiver is alerted to
come to change the diaper.

11. She recovers the reusable
temperature sensor (1); she
discards soiled diaper (2);
and installs the sensor into a
fresh diaper (3). That`s it!

12. SECOND IDEA:
Disposable Personal Toilet (DPT)
for Bedridden, Wheelchair, and people with limited mobility
(Imagine your diaper is wet and you can´t move)

13. Take a piece of hydrophilic cotton (17),
like a cotton dish used to remove makeup.
Compress one end of the fibers and insert
them with pressure into a 3mm flexible
hose (16) until it is tight. That`s it!
You have created a urine extraction device,
it will remove urine by capillary forces once
inserted into a diaper pad under suction.
Now. Let`s put it together with the
previous Temperature Sensing Invention.
Let me explain first what is a
urine extraction device

14. This is the system, let me start explaining Step by Step

15. 1-We start with a disposable adult brief,
the core made with PULP and a good
Liquid Acquisition Distribution Layer(*)
(*)Any adult brief with a good ADL, with most SAP removed will do. It may
also work with SAP but it may not be as efficient.

16. 2-We add a wireless temperature sensor
this wireless sensor will be reusable.
(*)There are many commercially available, many ranges to choose,
They are low cost and battery can last for months.

17. 3-Add a small flexible hose (3 mm)
with the compressed cotton fibers, as it
has been explained (*).
This is the “disposable personal toilet”
DPT for short (I suggest 4 to 6 per day)
** IT IS DISPOSABLE!! **
(*)Take a cotton dish, compress the cotton fibers at one end and force
them inside the flexible hose (this is our capillary extraction system)

18. 4-Connect the Personal Disposable Toilet to the automatic suction system.
Cost of (PDT) is similar to a disposable brief!! With all the advantages.

19. 5-Adding a pushbutton and the patient can dry by herself or by himself.
Add a container and you will know the exact Diuresis of your patients.
Last step: Make sure to license this
technology (Extremely low fees –Really)
(*) Patent Pending at the USPTO Inventors: V. Marconato & C. Richer1-Dry Skin=Healthy skin
2-No smell (no masking)
3-More independence.
4-Simple Diuresis.
5-Similar Cost.
6-More Ecological.

20. How does it work?

22. How does it work? Step by step
1-When the user insults the diaper with urine, it will wick the absorbent pad inside
the diaper until it reaches the wireless temperature-sensing transmitter 15.
2- This sensor is placed so it is touching the pad, outside of the backsheet
3-A wireless receiver 18 is monitoring the temperature of the backsheet and as soon
as it complies with the desired set point (a temperature gradient), it will close an
electrical circuit that will turn on the suction pump 19.
4-The suction pump 19 is connected to a suction means inside the absorbent core 17
using a flexible hose 16. The hose is flexible but strong enough to resist collapse
from the vacuum.
5-Because the fibers are wet and under compression, they create an effective seal
with the suction point that helps prevent the entrance of air bubbles, forcing the
movement of the liquid by capillarity and liquid extraction to start.

23. 6-Urine begins to be extracted from the diaper and collected in an optional reservoir
20, or directly discharged to the WC, 22.
7-After an optional timer integrated in the wireless receiver has elapsed, for example
3 minutes, the pump shuts down completing a urine extraction cycle.
8-The system remains in stand by waiting for a new cycle (a new temperature pulse).
9-It is also possible to start a urine extraction cycle using a manual push button that
produces the same effect as the detection of the temperature-sensing transmitter.
10-After a suitable time or after a few urine extraction cycles, the diaper is removed
and discarded and replaced with a new diaper. We suggest 4 to 6 DPT`s per day.

You may already know somebody without
mobility in need of such a solution,
in a few more years… it may be you!
