The portable ventilator of the present invention provides 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. A portable ventilator of a second preferred embodiment includes a sole dual-head compressor that operates to provide a consistent and continuous inhalation and exhalation cycle.

A ventilator device (10) includes a display screen (50, 101) to display a plurality of ventilator functions / modes (or menus) and a plurality of parameters (or sub-menus) associated with at least one of said ventilator functions / modes. A control member, e.g., in the form of a multifunction finger-operable dial (55, 102) is provided to select from the plurality of ventilator functions / modes and / or parameters, the dial being manipulatable in a first manner (e.g., rotation) to scroll between said parameters, and being manipulatable in a second manner (e.g., touching, pressing and / or depressing) to select one of the ventilator functions / modes and / or parameters.

The invention comprises a ventilation apparatus and method for operating a ventilator of a ventilator apparatus, wherein in the method at least one duration ratio factor is set in a computing system of the ventilator apparatus; at least one minute volume, at least one functional dead space volume and at least one time constant are determined; a respiration frequency is computed, based on a previously defined lung model, depending on said determined parameters, where said computed respiration frequency is optimized on at least one minimum of a delivered parameter, which is induced to a patient using said ventilator; an inspiratory time and an expiratory time are determined based on said computed respiration frequency and said duration ratio factor; at least one tidal volume based on said previously computed respiration frequency and said determined minute volume is computed; and a delivered respiratory parameter of the ventilator is closed loop controlled.

A ventilator adaptor for switching between ventilator devices while maintaining respiratory support to a patient is described. The ventilator adaptor has a first movable element with a first inlet and a second inlet, and a second movable element movably attached to the first movable element and with an outlet. The outlet has an inner diameter of 14.5-15.5 mm, preferably 15 mm, and the first inlet and the second inlet have an outer diameter of 14.5-15.5 mm, preferably 15 mm. The outlet is in fluid communication with the first inlet in a first position or with the second inlet in a second position by moving the second movable element relative to the first movable element thereby aligning the outlet with the first inlet or the second inlet. The outlet may be attached to an endotracheal tube in order to form a ventilation assembly.

A respiratory support ventilator apparatus mechanically supports the work of respiration of a patient. The ventilator apparatus is highly portable and optionally wearable so as to promote mobility and physical activity of the patient, and to improve the overall health of the patient. The respiratory support ventilator may monitor a physical activity level and overall health status of the patient, and process this information. The information is used to track efficacy of the ventilation therapy relative to activity level and quality of life, and or to titrate or optimize the ventilation parameters to improve, maintain or optimize the physical activity level and overall health status of the patient.

The invention discloses an ARM-based ventilator equipment detection remote monitoring system and method. According to the ARM-based ventilator equipment detection remote monitoring system, a wireless sensor network is responsible for data acquisition and transmission; a valve control module controls the exhaust air rate of an entrance pipeline and the working state of a ventilator; an ARM-based monitoring platform is responsible for data display and processing as well as remote control; when detecting data anomalies, the monitoring platform can wirelessly and remotely control an electric valve to automatically control pipeline output exhaust air rate, can further start a self-cleaning device to perform cleaning, and therefore, intelligent remote monitoring of the working condition of the ventilator can be realized; an alarm circuit can be driven, so that a wireless connection with a mobile handheld device can be established, and therefore, the owner of the mobile handheld device can know the working condition of the ventilator in real time; manual adjustment can be realized through a manual valve; since an electric and manual valve double-control complementary mode is realized, timely failure handling can be benefitted; and therefore, on the whole, efficiency can be improved, usability and compatibility can be also improved, and the stability and reliability of the system can be ensured.
