Once again, our development team showed great skill and used its expertise to solve a problem in the field of medical technology. The Suprasorb CNP P3 from renowned manufacturer Lohmann & Rauscher (L&R) is a negative pressure therapy device for wound care. It is established on the market, but various components that were previously used in it are no longer available. Therefore, a redesign of the electronics was carried out in order to secure production for the future.
