Respisense™ was produced as the world's first perfectly portable, ultra-safe baby monitor with proactive TummyTickle™ tactile stimulation. Here is what the prototype looked like:
The Respisense™ prototype


Design History

Respisense™ was designed by a loving father after the birth of his own triplets. Because of the inherent advantages the triplets' parents had them sharing a cot for their first six months and wanted a monitor that could work in such a set-up.

Nothing of the sort was available at the time, so their father designed and developed the pioneering Respisense™ tummy movement monitor.

A mother's wish list found on the Internet provided a useful guide and the motivation for the TummyTickle™ tactile stimulator: "... as a mother...", she wrote, "I do have some suggestions as to what I'd like in a monitor:

  1. It should not cost much more than a regular baby monitor. Poor babies get SIDS, too.
  2. It should be small enough and comfortable enough to wear that it does not wake up the baby, or make the baby hot/sweaty/sticky/itchy. No one is going to want to use a baby monitor that keeps the baby from sleeping. They will use it if they know their baby has an apnea problem, but ideally, this should be something all babies could wear easily. Because none of us can be sure our baby doesn't have an apnea problem.
  3. It also needs to be highly portable (and battery operated). I like the mat idea mentioned in prior posts, but what if the baby falls asleep in the car-seat, stroller, baby-carrier or your arms?
  4. Piercing alarms are scary. If apnea is a somewhat common occurrence in infants, with only a limited number of occurrences leading to SIDS, we could be dealing with a lot of loud, terrifying alarms. It would be nice if after, say 5 or 10 seconds of missing motion, a warning buzz would go off - something just loud enough to disturb the baby into breathing without waking him/her up completely."

- S.G. Lueck, 6 May 2002

Respisense™ was produced as the world's first perfectly portable, ultra-safe baby monitor with proactive TummyTickle™ tactile stimulation; the first monitor to satisfy all the requirements stated by Ms. Lueck.

Today the triplets are healthy and growing up fast, and Respisense™ monitors are available to parents across the globe to help raise their children safely.

Safer design
The principle operation of the Respisense™ is similar to that used by the traditional movement monitors, although the implementation of the principles into a more functional form is radically different and the source of its numerous advantages over older designs.

The electronic circuitry was shrunk dramatically by using circuit components that are very small and use exceptionally little electrical current. Doing so enabled the developers not only to make the unit about 30 times smaller and 20 times lighter than a monitor of traditional design, but to increase its safety by eliminating all wires and giving it a permanently sealed life-time battery. This removed all hazards of limbs or necks caught in cables or straps, batteries being swallowed or choked on, and babies being electrocuted by mains connections. It also eliminated bad plug connections, the source of many false alarms, and extended the usefulness of such monitors by being able to accompany baby when he/she leaves the cot. Mothers are no longer reminded too late to switch off the alarm when they pick baby up, which often results in the whole household being awakened in the dead of night just because she wanted to breastfeed, and if mother should want to breastfeed in her bed she no longer has to worry that she might doze off during the process and so leave her baby unmonitored.

Making the monitor smaller and placing it in contact with the baby also allows a Respisense™ to gently stir baby with tactile vibrations, and being so small and light (weighing a mere 32g, or 1oz) allows the monitor to be used wherever baby may fall asleep. The perfect portability, safety, proactive stimulation, intelligent operation and extensive features of Respisense™ monitors are unsurpassed in the world of baby monitoring.

Finally, hooking a Respisense™ onto a baby's nappy isolates it well from external movements such as those caused by siblings sharing a bed. The design has therefore also managed to eliminate most external sources of erroneous operation that can lead to dangerous false negatives, allowing a respected medical professional and head of a renowned Italian neonatal facility to conclude "From our experience we can confirm good tolerance of the device from the infants, and no false positive alarms were registered during the different periods of use."

Proactive response
Another Respisense™ first. The idea of using a little vibrating motor, the TummyTickle™ stimulating mechanism, came to the inventor when he realised just how little effort is used to stimulate babies in neonatal wards that suffer apnoea episodes: a nurse would usually simply tickle the baby's feet, back or tummy. Adding a little motor, like those used to make cell phones vibrate, to do the tickling was a simple and elegant addition. The tactile vibrations efficiently tickles baby's tummy through a gentle contact area of over 15 square centimetres.

From our prototype that we had working in October 2003, every version and model has been tested night after night on the inventor's own triplets. When the final model was ready in early 2005 the developers also tested these monitors on various babies from pre-term (26 weeks gestational age) to 2-year olds.

Respisense™ monitors were also tested in laboratories to determine the toxic safety and flammability of the materials, the susceptibility of the monitors to external electrical noise, and the amount of radiation they generate during operation. As was expected, all tests were passed and the device earned the CE mark of safety accreditation from TUV Rheinland Quality Services (www.tuv.com).

In addition, an official medical opinion expressed by a renowned department head of an important neonatal clinic in Naples, Italy underscores the efficiency of these amazing little devices.

Finally, the thousands of babies across the world already successfully using Respisense™ devices and the confirmed cases of successful intervention by parents after their babies became dangerously inactive further underscore the immense value of Respisense™ monitors.

Development team appointed
In September 2006 Infantrust came to realise that its unique new invention deserved a brighter future, and two months later appointed a highly qualified and exceptionally cooperative team to take the product with confidence into that brilliant future.

The newly appointed engineering team was able and willing to implement with little fuss and in record time all the original requirements of the inventive father, and new features were added to further improve users' experiences. Independent professional trials in Europe confirmed the value of Respisense™ monitors and feedback from satisfied parents proved that the redeveloped Respisense™ was a hit with all.

Respisense™ has appeared in numerous publications and on various television news and information channels in Europe, and even though imitators may follow, Respisense™ will always lead.

Safety Accreditation
The Respisense's CE-certification is not done as a self-declaration, but as a CASCO System 5 certification, equivalent to an EEC Model H (full quality assurance), by TUV Rheinland Quality Services as a third-party certifier equivalent to a Notified Body, appointed as the Authorized Representative of Infantrust Parenting Solutions (Pty) Ltd.

The Respisense™ is classified as a child care article and rated alongside items such as pacifiers, diapers and feeding bottles. As a child care article, in the absence of a child care article directive, the Respisense™ is certified under the General Product Safety directive (on the basis of the Rapid Information Interchange or RAPEX system established under this directive), taking into consideration relevant safety requirements from the Safety of Toys directive (viz. flame propagation test, migration of certain elements test) and guidelines published as FD CEN/TR 13387 "Child Use and Care Articles -- Safety Guidelines" by the Technical Committee CEN/TC 252 "Child Use and Care Articles". Other directives applied to the Respisense™ are the EMC directive and the WEEE directive. Because the circuitry uses a maximum of 3 Volts and no conductive parts make contact with a human body, the Low Voltage directive is not applicable, and a Safety Extra-Low Voltage declaration was made.

Respisense™ also carries FCC clearance for a class B digital device.
