A neck strap, a crown strap assembly and a headgear for a breathing mask. The neck strap for a headgear includes a one-piece main body adapted to engage a patient's neck, first and second lower connection portions adapted to connect to first and second lower mask connection straps, and first and second upper connection portions adapted to connect to respective first and second lateral crown straps.

A resuscitation management system for a manual resuscitator may include a radio frequency identification (RFID) tag that may be configured to be mounted on a first side of a bag of the manual resuscitator. The RFID tag may be configured to transmit information indicative of the presence of the RFID tag. The system may further include an RFID reader that may be configured to be mounted on an opposite second side of the bag. The RFID reader may be configured to generate an output signal corresponding to the presence of the RFID tag responsive to receiving the information transmitted by the RFID tag. The RFID reader may be configured to receive the information transmitted by the RFID tag responsive to the RFID tag being at a distance from the RFID reader smaller than a predetermined threshold.

A flow of gases in a respiratory therapy system can be conditioned to achieve more consistent output from sensors configured to sense a characteristic of the flow. The flow can be mixed by imparting a tangential, rotary, helical, or swirling motion to the flow of gases. The mixing can occur upstream of the sensors. The flow can be segregated into smaller compartments to reduce turbulence in a region of the sensors.

Compositions and methods for inhibiting and interrupting biofilm formation, and for destabilizing established biofilms are provided, the novel compositions including polymeric resins and monomeric non-polymerizable and polymerizable resins. More particularly, the compositions and methods enable the protection and removal of biofilms from surfaces in the context of medical, consumer, domestic, food service, environmental and industrial applications, where the effects constitute beneficial and desirable biofilm attenuating activity.

Disclosed is respiratory assistance apparatus comprising a flow generator configured to provide breathing gases to a patient, the breathing gases comprising supplemental oxygen provided from an oxygen source. The respiratory assistance apparatus controller is configured determine a target oxygen concentration of the breathing gases and calculate an estimated future value of the patient's blood oxygen concentration based on a difference between an initial oxygen concentration of the breathing gases and the target oxygen concentration of the breathing gases, and the patients blood oxygen concentration.

A safety breathing apparatus has a sensor for measuring the difference in pressure between two point 1a, 1b in the gas delivered to a head unit 9. The sensor is used to measure the difference in the pressure of the gas supplied through the apparatus between the two points in the gas flow, and the pressure difference is then used to calculate the gas flow rate.

Disclosed is a port connector for respiratory gases tubes. The port connector having a port extending from the port connector, the port providing for a passageway into a lumen of the port connector. The port having a connection mechanism, and a port sealing surface. The port connector may further comprise a connector elbow having an accessory end configured to connect with an accessory, a connector elbow sealing surface, and a collar located at a port end of the connector elbow. The collar may be configured to engage with the connection mechanism of the port connector to urge a connector elbow sealing surface into engagement with a port sealing surface.

A sedation device has a housing divided internally into a ventilator chamber and an associated evaporator chamber which overlap and are separated by a filter mounted between the chambers and forming a common gas-permeable dividing wall between the chambers. An inlet port is provided at one end of the ventilator chamber at a top of the housing for connection to a patient ventilator in use. An outlet port on the evaporator chamber can be connected via a breathing tube to a patient. An evaporator is mounted within the evaporator chamber for delivery of a volatile sedative into the evaporator chamber during use.

Devices and methods for monitoring physiologic parameters are described where an airway device, in one embodiment, may comprise a mouthpiece section and an opening section defining one or more airway lumens therethrough with a first sensor in fluid communication with the one or more airway lumens and a second sensor positioned upon a hand-piece for contact against a portion of the user. The first sensor may be configured to detect an airway pressure when a user inhales or exhales through the one or more airway lumens, and the second sensor may be configured to detect a physiological signal from the user. Additionally, a controller may be in communication with the first and second sensors where the controller is programmed to correlate pressure oscillations in the airway pressure with heartbeats.

A blower of a CPAP device is housed inside a main body case of a CPAP device. The blower is roughly divided into a fan unit housing a fan therein, and a delivery tube, through which air sent from the fan passes. In the main body case, a first support member, a second support member, and a third support member are interposed between the main body case and the fan unit to support the fan unit. When viewed from a rotation axis of the fan, the first support member and the second support member are disposed to pinch the blower on the side of a connection point between the fan unit and the delivery tube relative to the rotation axis, and the third support member is located on the opposite side to the connection point between the fan unit and the delivery tube relative to the rotation axis.
