Abstract
Abstract Mobile self-contained ventilator having a framework and a compressor carried by said framework. The compressor has a motor and at least one fan driven by the motor which causes air to pass over the motor for cooling the motor and for picking up heat from the motor. The compressor also has an output through which compressed air is supplied. A respirator is carried by the framework and includes at least one oscillator cartridge having an inlet connected to the outlet for receiving compressed air from the outlet. The oscillator cartridge is disposed so that air, after it has passed over the motor, passes over the cartridge to heat the cartridge to inhibit moisture condensation within the cartridge.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
157 words
In a mobile self-contained ventilator, a framework, an air compressor mounted on said framework, said air compressor having motor means and an adjacent compressor means and at least one fan driven by the motor means axially aligned therewith which causes a unidirectional flow of air to pass over the motor means for cooling thereof by picking up heat therefrom, said compressor means having an output through which compressed air is supplied, at least one oscillator cartridge means having an inlet connected to the outlet of the compressor means and an outlet and means for connecting said outlet to a patient said one cartridge means being mounted on the framework and in general alignement with the motor means and fan downstream thereof so that the unidirectional flow of air, after it has passed over the motor means, passes over said one cartridge means to heat said one cartridge means to inhibit moisture condensation within said one cartridge means.
Claim 2
Dependent Claim
157 words
In a mobile self-contained ventilator, a framework, an air compressor mounted on said framework, said air compressor having motor means and an adjacent compressor means and at least one fan driven by the motor means axially aligned therewith which causes a unidirectional flow of air to pass over the motor means for cooling thereof by picking up heat therefrom, said compressor means having an output through which compressed air is supplied, at least one oscillator cartridge means having an inlet connected to the outlet of the compressor means and an outlet and means for connecting said outlet to a patient said one cartridge means being mounted on the framework and in general alignement with the motor means and fan downstream thereof so that the unidirectional flow of air, after it has passed over the motor means, passes over said one cartridge means to heat said one cartridge means to inhibit moisture condensation within said one cartridge means.
Claim 3
Dependent Claim
40 words
A ventilator as in claim 1 together with an enclosure mounted on said framework and enclosing said air compressor and said one cartridge means so that a thermal balance is established within the enclosure during operation of the air compressor.
Claim 4
Dependent Claim
44 words
A ventilator as in claim 1 together with an additional fan means mounted on the fraemwork for directing air over the compressor motor means in a direction transverse of the axis of alignement of the compressor motor means and said at least one fan.
Claim 5
Dependent Claim
16 words
A ventilator as in claim 3 together with an additional housing enclosing said additional fan means.
Claim 6
Dependent Claim
33 words
A ventilator as in claim 2 wherein said means for connecting to a patient includes a patient adapter and means for connecting the outlet of said one cartridge means to the patient adapter.
Claim 7
Dependent Claim
39 words
A ventilator as in claim 5 wherein said means for connecting to a patient also includes a nebulizer disposed exterior of the enclosure in said means for connecting the outlet of said one cartridge means to said patient adapter.
