A Thermally Isolated Blood Carrier Tray includes a main panel having a plurality of thermally isolated compartments attached thereto. The thermally isolated compartments are arranged in two separate matrices having a plurality of column and rows. Each thermally isolated compartment is thermally isolated from an adjacent thermally isolated compartment. Each thermally isolated compartment maintains its own heat transfer rate without being affected by an adjacent thermally isolated compartments heat transfer rate. The placement of several different storage units having different temperatures into the Thermally Isolated Blood Carrier Tray does not affect the heat transfer rate of any one storage unit in a thermally isolated compartment. The Thermally Isolated Blood Carrier Tray provides a steady and even heat transfer from the storage unit to bring the storage units to an appropriate temperature for storage or transportation.

Architectures for production of nitric oxide (NO) include systems and methods for generating NO having one or more plasma chambers configured to ionize a reactant gas to generate a plasma for producing a product gas containing NO using a flow of the reactant gas through one or more plasma chambers; a controller configured to regulate the amount of nitric oxide in the product gas using one or more parameters as an input to the controller, one or more parameters including information from a plurality of sensors configured to collect information relating to at least one of the reactant gas, the product gas, and a medical gas into which product gas flows; and a flow divider configured to divide a product gas flow from the plasma chamber into a first product gas flow to provide a variable flow to a patient inspiratory flow and a second product gas flow.

A heating cabinet for IV bags provides a uniform thermal field promoted by circulated heated air passing through air permeable shelves. IV bag temperature is modeled through a knowledge of the uniform thermal field temperature and arrival time of the IV bag eliminating the need for separate temperature sensors and control loops. Bag status may be signaled through modulated light distinguishable by individuals with limited color sensitivity. Signals are associated with particular IV bags by projecting the signal light into the bag itself.

A multifunctional smart cushion includes a smart cushion main body and a mobile terminal. The smart cushion main body includes a smart cushion cover, a structural portion, and a core portion. The structural portion is located around the core portion. The smart cushion cover covers the structural portion and the core portion. The structural portion is provided with a power supply and a controller. The core portion is provided with a fan, a heater, a temperature sensor, a reflux guiding channel, a therapy device, and a massage device. The fan, heater, temperature sensor, therapy device, and massage device are all connected to the power supply through the controller. The mobile terminal is connected to the controller via a wireless communication.

Methods and apparatus provide automated circuit disconnection monitoring such as for a respiratory apparatus or system. Disconnection of a patient circuit, including a patient interface and air delivery circuit, may be detected and a message or alarm activated. In some versions, detecting occurrences of circuit disconnection event(s), such as by a processor, may be based on an instantaneous disconnection parameter as a function of a disconnection setting. The disconnection setting may be determined based on patient circuit type. The instantaneous disconnection parameter may be determined from detected pressure and flow rate, and may be, for example, a conductance value or an impedance value. Disconnection events may be qualified by one or more detected respiratory indicators. In some cases, instantaneous impedance or conductance may be used to assess re-connection of a patient circuit, detection of flow starvation, determine breath shape for triggering and cycling and to detect patient or circuit obstructions.

A portable device for oxygen generation comprising at least one reservoir for holding a hydrogen peroxide solution, a reactor, for reacting hydrogen solution with a catalyst, a feeding system for supplying said hydrogen peroxide solution to said reactor from said reservoir, a system for cooling, interconnected to an outlet of said reactor, a hydrophobic filter membrane, for removing water at an oxygen outlet of said cooling system and an oxygen flow regulator, for regulating oxygen flow at said oxygen outlet.

A ventilation system including a ventilator having a cooling fan configured reduce an internal temperature of the ventilator. The ventilator also includes a controller configured to control operation of the ventilator. A detector is configured to generate a detection signal when the ventilator is connected to a cold passover humidification (CPH) device. In response to the detection signal, the ventilator reduces or eliminates operation of the cooling fan in comparison to a default mode of operation. A method of providing increasing a temperature of a flow of air to a CPH device is also included.

The pneumatic unit is designed as a pneumatic conveying line which is removable from the housing and which is formed and arranged from an appliance inlet to an appliance outlet of the housing and comprises a support frame on which are arranged at least one component, in particular the respiratory gas drive, at least one sound unit, at least one flow measurement path, at least one measuring unit and the cooling fan.

A battery retaining system for a portable oxygen concentrator includes a first rail configured to receive a first slide of a battery, a second rail configured to receive a second slide of the battery, the second rail being spaced apart from the first rail so as to form a channel configured to receive the battery, and a flexible stiffening mechanism configured to impart a biasing force on a surface of the battery when the battery is received within the channel. The flexible stiffening mechanism includes a protrusion projecting from the first rail at least partially towards the second rail and a slit positioned behind the protrusion and configured to facilitate travel of the protrusion fore and aft.
