  • Patent number: 4215681
    Abstract: A respirator is provided for the treatment, particularly in the home, of persons suffering from respiratory insufficiencies. The respirator comprises a reciprocating linear electric motor compressor having a gas intake orifice connected to atmosphere for example, a compressed gas discharge orifice connected to a respiratory mask, a piston, a spring acting on the piston, and an electromagnet for moving the piston against the action of the spring to supply compressed gas to the mask via the discharge orifice. A thyristor pulse generator is controlled by a clock to provide pulses to the electromagnet to define the insufflation time. The compressor operates only during the insufflation time.
