THE COMPANYall about redsense blood loss detection

Headquartered in Halmstad in the south of Sweden, Redsense Medical began as a project in 2000 with the goal of developing the first monitoring system for venous needle dislodgement during HD, and in 2006 it was incorporated into the legal entity Redsense Medical AB. The Company was founded as a spin-off from the Swedish company Innovation Team, which is a well-established design company within the medical device sector, to develop and commercialize its proprietary technology.

In 2000 and after a number of incidents with venous needle dislodgement during HD at the dialysis clinic, Halmstad County Hospital in Sweden, the clinic’s key technician realized that these incidents were far from unique, and that existing alarm systems were widely notorious for malfunctioning. The technician contacted Daniel Engvall, cofounder of RSM, looking for a solution to this problem. Together, and with input from the local university, they developed the first ever product to solve what has been a well-known problem with HD – to efficiently and securely monitor blood access points. The team’s extensive collective experience of medical technical products and systems enabled them to solve the problem.

In late 2003 the development of the first product prototype was finalized and in 2004 a patent protecting its basic technology was filed. During the development process, the team evaluated existing methods and, instead of attempting to measure activities inside the body or the dialysis equipment, designed a device which keeps an eye on the access points and monitors for the first sign of blood loss. An absorbent patch, which contains a blood sensor, is placed directly over the venous needle blood access point to absorb the blood that flows out from the patient in a situation where venous needle dislodgement occurs. The sensor inside the patch is connected to an external alarm unit to allow the sensor patch to be as small and simple as possible. Another important benefit of the solution is that it enables reuse of the alarm unit.
