LIMBS AND THINGS
PROMPT Flex Birthing Simulator
Classic innovation of an existing product: From concept to production
Limbs & Things are a Bristol based company that develop and manufacture medical training products for healthcare professionals and students worldwide. In 2006, they launched the PROMPT Birthing Simulator which quickly became one of their most successful products.
The PROMPT is an anatomically correct simulator that replicates both normal and difficult birthing scenarios. Following its success, Limbs & Things were keen to develop the product further and approached Cubik for assistance with a redesign.
The main objectives of the redesign were to remove the cabled umbilical connection to the control PC application, replace it with a Bluetooth connection and update the application software to run on multiple platforms.
Using our standard 5 phase process, Cubik innovated the existing design to include a range of new features:
-
- Force measurement using load cell technology.
- Internal Lithium power source.
- Contactless inductive charging system.
- Bluetooth classic and Bluetooth LE communications to the host.
- Cross-platform control application (developed in conjunction with our approved partner).
- Boot-loadable baby firmware, user upgradable to future-proof the design.
In addition to redesigning the baby electronics, embedded firmware, application software and charge dock, Cubik developed test rigs for the electronics and calibration software. This meant that the electronics could be set up and calibrated during the manufacture process to ensure the customer received a system that was ready to be fitted into enclosures and over moulded into babies. We also provided a contactless charging dock and application software to run on Windows, Android, iPad and MAC operating systems.
Following the success of the redesign, we supported Limbs & Things through compliance testing to successfully achieve CE and FCC marking which allows them to sell the PROMPT Flex in the UK, EU and USA.
Our in-house production department continue to manufacture and deliver fully assembled electronic kits in batches of 100 ready to be moulded into the baby.
