Vorrichtung und Verfahren zum dosierten Ausbringen eines viskosen Mediums

WO2005012845 A UPAB: 20050311 NOVELTY - Device for dosed application of a viscous medium comprises a cartridge-needle unit with an actuator driven piston. The piston has a piston head that enters into the cartridge to dispense the medium. Attached to the head are pressure and temperature sensors that contact the medium. A control unit controls the volume output from the dosing device based on the measured temperature and pressure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is made for a method for dosing viscous media in which temperature and pressure are measured and used by a control unit during dispensing. USE - Metered discharging of doses of a viscous medium, e.g. for use in medicine, microctechnology, microelectronics for injection or delivery of medicaments, for application of controlled lubricant amounts or for application of glue in microelectronics fabrication. ADVANTAGE - Accuracy of dispensing is greatly increased by taking into consideration temperature and pressure
