Self-contained micromechanical ventilator
First Claim
1. 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.

Abstract
The portable ventilator of the present invention provide a hands-free ventilatory support device in critical care, emergency and resource limited environments. The portable ventilator utilizes ambient air and includes a two dual head compressor system to provide a consistent air supply to the patient. The ventilator device is battery operated and is capable of providing up to 60 minutes of care. In a preferred embodiment, the portable ventilator of the present invention also includes a pneumatic subsystem, a control subsystem, a power subsystem and an alarm subsystem. The portable ventilator of the preferred embodiment includes a dual head and single head compressor system that operates alternatively, to provide a consistent and continuous inhalation and exhalation cycle.

7. A method of operating a portable ventilator comprising the steps of:
-
(a) drawing ambient inhalation air into a dual head compressor, (b) compressing said ambient air in said dual head compressor and monitoring the pressure of said compressed air while maintaining a single head compressor in an off position; (c) transferring the compressed inhalation air into an air manifold and causing a flutter valve to open; (d) transferring said compressed inhalation air from said manifold to said flutter valve through an input port; (e) transferring said compressed inhalation air to a patient through a second bi-directional port in said flutter valve; (f) maintaining an exhale port of said flutter valve closed when operating said dual head compressor; (g) operating single head compressor to close off said input port and open exhale port, turning off said dual head compressor at the point when single head compressor is turned on, and allowing exhalation air from said patient to enter bi-directional port; (h) transferring exhalation air through said exhale port and verifying the presence exhalation air using a second sensor; and (i) removing exhalation air from said ventilator, through a patient exhale port. - View Dependent Claims (8, 9, 10, 11)
