Photonics healthcare is a prominent player in the field of oxygen measurements in the blood with a very high accuracy. They did this by developing the Comet. This measuring system ensures that oxygen can be measured in all parts of the body by means of a non-invasive technique. In order to get a good measurement with the Comet, there are a number of factors that influence, for which a product has been developed.

The Comet sensor holder is the result of extensive testing methods combined with a production technique that can be used on a small scale. Over 30 different versions of the sensor holder have resulted in an accurate, biocompatible and MDR compliant product during the process.

The sensor holder is made of a special kind of plastic that works well in combination with sticking to human skin. The product is made with a 3d printer where the settings are very closely adjusted. In this way a constant quality can be delivered, so that the use of the product can be guaranteed.

The geometry can be directly related to the intended use, whereby placement, pressure, incidence of light and any external forces are minimized or can lead to intended rupture.

After devising the sensor and doing more than 30 tests, Photonics Health Care needed an MDR certified product for hospital use. This complete process was developed from start to finish in collaboration with Photonics healthcare and hospital professionals. The following aspects were discussed during this project:

• Mechanical design
• User Research
• Regulatory examination
• Prototyping
• industrial design
• Production
