A lighted air supply delivery assembly for use in delivering air to a patient is described herein. The lighted air supply delivery assembly includes an air/light connection tubing coupled between an oxygen concentrator and a patient oxygen delivery. The air/light connection tubing defines an airflow chamber for delivering a flow of oxygenated air from the oxygen concentrator to the patient oxygen delivery assembly, and includes one or more optical fibers positioned within the airflow chamber. A fiber-optic light engine coupled to the one or more optical fibers. A controller is coupled to the fiber-optic light engine and includes a processor programmed to execute algorithm steps of operating the fiber-optic light engine to display a light visible through the air/light connection tubing via the one or more optical fibers.

An aerosol delivery device may include a rechargeable power source configured to provide power to generate an aerosol, device electronics configured to generate the aerosol responsive to application of the power from the power source, and an authentication module. The authentication module may include a separate chip or circuit board relative to the device electronics. The authentication module may be inserted into the aerosol delivery device between the power source and the device electronics to control provision of the power to the device electronics for generation of the aerosol or between the power source and a charge port of the aerosol delivery device to control charging of the power source.

The present disclosure is directed to systems and methods of providing a mixed-gas inhalant to a patient via a gas recirculation loop. The gas recirculation loop receives a first mixed-gas exhalant having a first carbon dioxide concentration from the patient, one or more carbon dioxide removal devices discharge a second mixed-gas exhalant having a second carbon dioxide concentration that is less than the first carbon dioxide concentration. The second mixed-gas exhalant is combined with a mixed-gas supply to provide a mixed-gas inhalant. The mied-gas supply includes a first gas and a second gas. The mixed-gas supply is pressure and flow controlled to produce a mixed-gas inhalant having a defined composition delivered to the patient at a defined volumetric flow rate. The first gas may include a gas containing oxygen and the second gas may include a gas mixture containing a noble or inert gas and oxygen.

Implementations of the present disclosure are directed to an injection device including: a reservoir including a wall defining a proximal end, a distal end and a tubular side, a plunger rod configured to be movable within the reservoir in a direction from the distal end to the proximal end, a radio frequency (RF) antenna attached to the tubular side and configured to receive an interrogation signal from an external device, and a resonating assembly configured to receive the interrogation signal from the RF antenna and to generate a modulated RF signal having a frequency associated with a position of the plunger rod.

A resuscitation device includes a first resuscitation unit configured to perform a first resuscitation function and having front and back sides. A second resuscitation unit is configured to perform a second resuscitation function, which is different from the first resuscitation function, and includes front and rear sides. The first and second resuscitation units are configured so as to be assembled together as a single assembly such that the first and second resuscitation units can be carried conjointly for selectively performing at least one of the first and second functions. An adaptor is also provided for connecting a defibrillator to a plurality of different electrode pads.

Systems, devices, and methods for treating a tissue site on a patient with reduced pressure are presented. In one instance, a reduced-pressure treatment device to treat a tissue site with reduced pressure may include a pump control unit fluidly separate from a collection unit. Pump energy may be provided by the pump control unit to deflect one or more diaphragms within the collection unit to create reduced pressure. Other systems, devices, and methods are presented.

A medication delivery device having a lock element. The device is connectable to an electrical plug of a conduit. The device includes an external housing with an opening that ports to a plug receiving hollow within an interior volume. An electrical circuit connected to at least one of a rechargeable battery and a memory controller includes a connection element within the plug receiving hollow. The lock element travels within the plug receiving hollow when a dose delivery assembly of the device operates for forcing medication from the device. The lock element is sized and positioned to have its travel halted by abutment with the plug, when the plug is within the plug receiving hollow and electrically interfacing with the connection element, to thereby halt the dose delivery assembly from further operating for forcing medication from the device.

A soft medical silicone edged cushion may significantly reduce air leakage and provide comfort to a wearer of a face mask, for example, when the face mask is continually worn by a healthcare worker for a twelve-hour shift of medical duty. The cushion may preferably be U-shaped and comprise a cross-section for holding an extra soft silicone gel or air, yet be sufficiently hard and elastic and of predetermined circumference to be adaptable to self-installation to the lateral edges of a face mask and coatable to protect from the escape of air and fit comfortably on a face despite the use of elastic straps with the face mask or the presence of solid plastic lateral edges of an oxygen mask or a ventilator mask. The cushion may be used to cushion a solid plastic laterally edged oxygen or ventilator mask against the use of elastic ties to tie the face mask around a patient's head. The face mask may comprise a UVC source of ultraviolet light controlled by buttons/displays/battery/USB charging port on the cushion or on a UVC cartridge replacing a filter of an N95 mask.

A drug delivery device for administering a drug is presented having a body adapted to retain a cartridge containing a drug, at least one electrical unit and a port for electrically contacting the electrical unit, an adapter for attaching an injection needle to the drug delivery device, a safety mechanism arranged to prevent contacting the electrical unit through the port whilst an injection needle is in fluid communication with the cartridge and arranged to prevent establishing a fluid communication between an injection needle and the cartridge whilst the port is configured to allow contacting the electrical unit.

The invention relates to a multifunctional applicator 6 for mobile use having an applicator plug 7, a supply tube 8, a Y-piece 9, fork tubes 10 and a nose piece 11 with prongs 12, wherein the applicator plug 7 comprises a pressure chamber 21 that has a humidifier interface 17 for connection with a high flow therapy device 1, an oxygen supply port 13 having an opening diameter of at least 1 mm, and a therapy air supply port 14 for the supply tube 8, the humidifier interface 17 and the oxygen supply port 13 within the pressure chamber 21 are both in fluid communication with an upper and a lower valve seat 23, 25 that are provided with a seal 22 and a valve body 24 being movable between said valve seats 23, 25 and said valve body 24 being subjected to a force by a helical compression spring 26 from the direction of the oxygen supply port 13 and on the other hand being pushed against the upper valve seat 25 by an actuating element 28 of the high flow therapy device 1 when the applicator plug 7 is locked in place on the high flow therapy device 1.
