Laser welding of medical devices in the medical engineering industry
Drug delivery system
Drug delivery systems (sometimes referred to as "drug dosing systems") assist patients by administering their medication constantly. Their increasingly compact design makes them comfortable to wear. One example is the Rowe-Pump, a physically powered pump that can be set to different dosages. The components are required to withstand an internal pressure of up to 4 bar. The welds must be completely free of particles, not least because of the stringent hygiene requirements associated with the device (which is used in direct contact with the patient) and the integrated micro-channels with diameters in the >10 μm range. The laser welding process allows these requirements to be met.
