Patent ID: 7721736

Claim:
A portable ventilator system comprising: a hard shell device housing having a recessed control panel, 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 comprising a battery monitor LED, a device/system error LED, a patient error LED and an audible alarm wherein said battery monitor LED, said device/system error LED, and said patient error LED are positioned on a recessed control panel of said exterior surface; said pneumatic subsystem comprising a dual head compressor constructed so as to provide a patient with inhalation compressed air; said control subsystem comprising a timing circuit connected to a logic circuit, said logic circuit connected to a relay, said relay further connected to said dual head compressor so as to turn said dual head compressor on so as to deliver inhalation compressed air to a patient, and turn said dual head compressor off when said patient exhales; said power subsystem comprising a battery source connected to a current limit device, 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 power switch connected to said battery, said power switch constructed so as to operate a buck/boost, said buck/boost constructed so as to accept a range of voltages from said power source and output a pre-set constant voltage; said power switch further connected to a voltage regulator, said voltage regulator constructed so as to supply lower voltages to said control and alarm subsystems; and said alarm subsystem further constructed so as to connect to said power subsystem and said battery monitor LED, said device/system error LED, said patient error LED and said audible alarm of said power subsystem so as to visually and audibly detect patient, device and battery problems in said ventilator system.
