Patent ID: 7320321

Claim:
A portable ventilator system comprising: a hard shell device housing having an interior portion and an exterior surface; said interior portion including a power subsystem connected to a pneumatic subsystem, a control subsystem, and an alarm subsystem; said pneumatic subsystem comprising a dual head compressor connected to a single head compressor, said dual head compressor and said single head compressor constructed so as to operate at alternate times; said control subsystem comprising a timing circuit connected to a relay, said relay further connected to said single head compressor and said dual head compressor so as to control on and off cycle between said dual head compressor and allow said dual head compressor and single head compressor to operate at alternate times; said power subsystem comprising a battery source connected to an electronic circuit which in turn is connected to a power jack, so as to supply regulated power to said pneumatic, control and alarm subsystems, said electronic circuit and said power jack further constructed so as to connect to an external power source; said power subsystem further comprising a voltage regulator circuit so as to eliminate fluctuations in voltage to said control subsystem, said power subsystem also comprising a second voltage regulator circuit so as to supply lower voltages to said control and alarm subsystems; said alarm subsystem connected to said pneumatic subsystem and further comprising an LED patient problem indicator so as to detect patient problems within said pneumatic subsystem; said alarm subsystem further comprising a failure detect circuit connected to a non-repairable LED indicator, said circuit and non-repairable LED indicator connected to said control subsystem, so as to visually detect non-repairable problems within said control subsystem; and said alarm subsystem further comprising a low voltage detect circuit connected to a repairable LED indicator, said circuit and repairable LED indicator connected to said power subsystem and so as to visually detect repairable problems within said power subsystem.
