Device development for telemedicine

Introduction

A base station called the "Health Buddy" is installed for a patient at home. The Health Buddy measures and transmits daily vital signs, symptoms, behaviour and knowledge of the patient. This information is sent to the telemedicine centre at the Robert-Bosch Hospital in Stuttgart. Patients receive individually tailored information through the base station, helping them deal more confidently with the illness over time. The telemedicine centre analyses the data daily and contacts the patient as well as the attending doctor if required. Participating family doctors and specialists have access to the parameter records of their patients at any time using a secure Internet application. (Source: telemedizin.fokus.fraunhofer.de)

Task

seleon was commissioned for the development of this device.

The following tasks were defined:

Mechanical systems
A housing concept was developed and implemented with the Solid Works CAD software in cooperation with an external design agency. 

The simplicity of the housing concept, the usability of the device, cost optimisation of the manufacturing processes and series production at minimal cost played an important role in the implementation of the product concept.

Transferring the product to series production was also part of the assignment.

Electronics
In cooperation with the customer, seleon modified the existing circuit with further development as a PCB and the layout for series production.

Results

seleon in close cooperation with the design agency and the customer developed a three-part housing concept. Functional models and prototypes were produced using rapid prototyping methods over several development stages. These were used for the qualification of the device. Based on the resulting insights, seleon was commissioned to select suppliers for the injection moulding tools and parts. This included contacting and auditing suppliers around the world. 
As a result of this selection process, the contract for tool building and the delivery of plastic parts was awarded to a Chinese company. seleon and the supplier were in close contact during this time.
The decision to launch series production was made by the customer. A supplier from a European foreign country was selected. This supplier was also commissioned  for the production of the PCBs.
seleon was chosen to coordinate tasks for the transfer to series production.
The project ended with the successful production of the zero series.
