Abstract: An aircraft store ejector systems and subsystems thereof. Embodiments can include a two-reservoir re-pressurization system wherein a remote reservoir is used to maintain desired pressure in a local ejector reservoir. The system can include a release valve having a vent valve and valve piston. The release valve can control release of pressurized gas to a pitch control valve. The pitch control valve can be configured to distribute the pressurized gas between two or more ejector piston assemblies. One or more of the ejector piston assemblies can include multiple concentric piston stages and piston chambers, the piston chambers configured to contain a volume of gas. The ejector piston assemblies can be configured to compress the volume of gas within the piston chambers as the piston stages are extended out from the aircraft. Such compression can provide a return force to the piston stages.

Abstract: A modular ventilator according to the present disclosure may include a ventilator core and a ventilator service module. The ventilator core provides the basic functionality necessary for delivering suitably oxygenated air to a patient without most or all typical patient monitoring functions except a basic alarm or safety alert triggered by loss of pressure at the output. Additional patient monitoring functions are embodiment in the removable ventilator service module, which may be powered by its own power source and/or by the power source of the ventilator core when coupled thereto. The ventilator core is configured for low cost manufacture and ease of operation and may be portable so as to be easily deployable in a non-hospital setting. The ventilator core may employ a venture-based O2 regulator for adjusting the oxygen-air mixture at the output, which may facilitate the manufacture of the ventilator core at lower cost than conventional ventilators.

Abstract: The specification describes anesthesia systems with an integrated, extendable clinical center and clinician/anesthesia office that accommodates for physical separation of clinical and clerical functions. The disclosed anesthesia systems allow for a portion of the system to be brought closer to the patient such that clinical controls can be accessed while tending to the patient airway, without compromising office space available to the clinician or crowding the patient area.

Abstract: The anesthesia systems have an integrated, extendable clinical center and clinician/anesthesia office that accommodates for a physical separation of clinical and clerical functions. The anesthesia system includes an alarm reversion system which enables a predefined alarm limit to be set and then to be automatically reverted back to an alarm limit existing just before the predefined alarm limit was set.

Abstract: A ventilator for ventilating a patient also assists a clinician in determining a suitable PEEP for the patient. For this purpose, a graph or tabular display of a series of different value PEEPs and corresponding functional residual capacities of the patient may be provided. Or, the relationship between lung compliance and a series of different values of PEEP may be provided. Or, the amount of the lung volume recruited/de-recruited at various levels of PEEP may be determined for use in selecting a desired PEEP. To this end, the functional residual capacity of the lungs is determined for a first PEEP level. The PEEP is then altered to a second level and a spirometry dynostatic curve of lung volume and pressure data is obtained. The lung volume on the dynostatic curve at a lung pressure corresponding to the first PEEP value is obtained.

Abstract: A method of integrating the operations of a ventilator and a nebulizer to conduct respiratory therapy is provided. In one example, the method includes the steps of (1) providing a control unit in communication with a ventilator and nebulizer, the control unit arranged to obtain a control value based upon one or more ventilatory control parameters associated with the respiratory therapy; (2) operating the ventilator to provide the respiratory therapy to a patient; and (3) generating a modification signal from the control unit to automatically modify an operating condition of the nebulizer based upon the control value.

Abstract: A system and method are for monitoring control signals provided to a medical apparatus based upon tactile feedback from the apparatus. The system and method employ a monitoring signal indicative of a parameter relating to the apparatus or to a condition of a patient associated with the apparatus.
