Magneto-pneumatische, intermittierende Saugvorrichtung

摘要

The device has a housing having a chamber. The chamber has a flexible diaphragm separating the chamber into first and second subchambers. The first subchamber has an inlet adapted to be connected to the source of vacuum and an outlet for applying vacuum from the source to the patient. The flexible diaphragm has a first position wherein the outlet is open to communicate vacuum from the vacuum source to the outlet and a second position wherein the flexible diaphragm closes the outlet to prevent communication of vacuum between the inlet and the outlet. The diaphragm is susceptible to magnetic forces, magnetic force device biasing the flexible diaphragm to the first position and a control unit to control the differential pressure between the two subchambers to move the diaphragm between the two positions at set time intervals.
