Respiratory phase controller

摘要

Respiratory phase controller for the control of the O2 supply via pressure changes during the breathing operation for an oxygen apparatus equipped with a pressure controller, a quantity controller and a nasal tube for medical therapy, comprising a low-pressure box with a membrane having a connecting nozzle for the nasal tube and connected on the other side with a switching contact for transformation of a pneumatic signal into an electrical signal, whose lines lead to a two-way solenoid valve which is known per se and which can be connected on the input side via a connecting nozzle for the pressure controller of the oxygen apparatus and on the output side via a similar connecting nozzle for the quantity controller, and a bypass line having one connection each for the quantity controller and for the nasal tube of the oxygen apparatus. <IMAGE>
