On February 24, 2015 , the USPTO issued U.S. Patent Number 8960194 to SPACELABS HEALTHCARE LLC., which was successfully prosecuted by Novel IP.
The '194 patent is directed towards a specification which discloses a ventilator system that can be manufactured quickly with minimal skill requirements and rapidly deployed in response to epidemic respiratory disease conditions. In one embodiment, the ventilator, having a minimal number of controls, is used to give ventilation or mechanical breathing to a patient suffering ARDS. The mechanical ventilation is based on pressure control and has variable pressure, breathing rate, and oxygenation. Preferably, the ventilator is rapidly deployable, easy and intuitive to operate, and capable of sustaining at least 75% of epidemic respiratory distress victims who require assisted ventilation until resuming normal breathing.
Independent Claim 1 describes " a kit for manufacturing a ventilator comprising: a first housing with internal structures formed to support enclosure of a first component set and a second component set, wherein the first housing further comprises at least one patient connection port and wherein the first housing comprises a first connector; a second housing with internal structures formed to support enclosure of a third component set and a fourth component set, wherein the second housing further comprises an exhaust port and wherein the second housing comprises a second connector that is configured to mate with the first connector; and a third housing with internal structures formed to support enclosure of an alarm printed circuit board (PCB), wherein the third housing comprises a third connector that is configured to mate with the second connector; and a printed circuit board (PCB) having an alarm circuit, wherein the first component set comprises a gas over-pressure relief valve and a valve cover, the second component set comprises a first diaphragm actuator and an inhalation conduit, the third component set comprises an O ring, let disc, and let cover, and the fourth component set comprises a bellows seal, first seal, top cover seal, electronics actuator, breathing rate control knob, and compressed gas interface, and wherein the ventilator without said alarm circuit being activated is adapted to operate without electricity".
