A medication inhalation apparatus includes an outer housing, movable between collapsed and expanded states, encompassing a first volume. An inner housing within the outer housing encompasses an inner volume. An inhaler opening to the first volume is within a wall of the outer housing at a first location. A mouth opening to the inner volume is within a wall of the outer housing and the inner housing at a second location. A one-way inhalation valve connecting the first volume and the inner volume is within a wall of the inner housing. A one-way exhalation valve connecting the inner volume and the exterior of the outer housing is within a wall of the outer housing and inner housing at a third location. In the expanded state, gas flows from the inhaler to the first volume, the first volume to the inner volume, and the inner volume to a user's mouth.

A safety syringe includes an outer barrel having a receiving groove located on an inner surface of a rear end thereof between a first annular flange and a second annular flange, an inner barrel having a needle mount located on a front end thereof and a positioning portion adjacent to the needle mount, and a plunger axially movably inserted into the inside of the inner barrel.

A needle and pre-filled syringe system that provides ultra-low dosage waste and automatic needlestick protection. A syringe assembly is pre-filled with an injection material. A needle head assembly attaches to the syringe assembly. A spacer is disposed between the needle head assembly and the syringe assembly. The spacer has a central opening. The needle head assembly supports a needle with a needle base. When assembled, the needle base passed into the central opening of the spacer. The needle head assembly also contains a safety slide that can selectively cover the needle. During an injection, pressure and/or contact with the plunger head causes the spacer to contact and move the safety slide. The safety slide moves to cover the needle during the injection procedure, therein rendering the needle safe before the injection process is even complete.

A medical connector for connection to a corresponding medical connector is described. The medical connector includes a housing having a radial protrusion and a cavity, the cavity defined by a closed end, an open end, a partially cylindrical sidewall and a radial sidewall. The medical connector further includes an insert disposed within the housing, the insert including a locking tab having at least one thread on the inner wall of the locking tab and a recessed notch on the outer wall of the locking tab. The at least one thread of the locking tab engages at least one thread of a corresponding medical connector. Disposed within the cavity, the recessed notch rotates from a first position to a second position, wherein the second position contains a locking structure for non-removably securing the insert to the housing, while allowing for removal of the corresponding medical connector.

Embodiments of the preset invention provide a fluid collector configured to releasably engage with an injector. The fluid collector comprises a fluid container configured to have a centrally extended conical projection containing a detachable needle holder at a proximal end of said conical projection to hold a detachable hypodermic needle, a piston assembly having a piston flange provided with a conical cavity at center of said piston assembly at a distal end of said piston assembly to couple said plunger shaft of said injector and a container cover being internally provided with a concave diaphragm having a central hole to allow entry of said detachable hypodermic needle along with a detachable needle hub.

A surgical gas delivery device includes a filter cartridge interface and a computer controlled control unit configured to control the circulation of surgical gas during endoscopic surgery. The control unit can operate in a plurality of different modes of operation. A tube set for connecting the surgical gas delivery device to one or more end effectors includes a filter cartridge in fluid communication with the tube set. The filter cartridge is seated in the filter cartridge interface of the surgical gas delivery device to communicate surgical gas between the surgical gas delivery device and the one or more end effectors. The surgical gas delivery device includes a reader operatively connected to receive input from a data carrying element of the tube set. The data carrying element, reader, and control unit can launch a specific one of the modes of operation when the filter cartridge is inserted.

A filtered face mask apparatus for CPAP applications can include a body, an inlet port, a mouth portion having a mouth exhaust port, a nose portion having a nose exhaust port, a plurality of adjustable straps, a seal, a mouth exhaust filter disposed over the mouth exhaust port, a nose exhaust filter disposed over the nose exhaust port, and an intake filter disposed over the inlet port. The inlet port may be configured for attachment to a gas supply tube that is attached to a CPAP device on the other end. The mouth exhaust filter, nose exhaust filter, and intake filter may each comprise a N95 or N99 material configured to block the passage of pathogens. A disposable filter patch and a method of operating a positive airway pressure device are also disclosed herein.

An air delivery system for providing a supply of air from a source of air at positive pressure to an interfacing structure located at the entrance to the airways of a patient includes a manifold adapted to connect with the supply of positive air pressure and at least one tube connected to the manifold and adapted to deliver the supply of air to the interfacing structure. Each tube is structured to allow movement between an open phase in which the tube allows the passage of air and a collapsed phase in which the tube is collapsed. Each tube is structured such that weight of a typical patient's head against bedding apparel is sufficient to collapse the tube from the open phase to the collapsed phase.

A safety needle device includes a housing including a passageway with a needle cannula extending therefrom. A shielding member is movable between a first position in which a puncture tip of the needle cannula is exposed therefrom and a second position in which the puncture tip of the needle cannula is encompassed therein. The shielding member is maintained in the first position against a biasing force which biases the shielding member toward the second position. A fluid and/or a temperature activation material is associated with the shielding member and is adapted to deform upon contact with a fluid medium and/or a certain temperature or temperature range. The fluid medium flowing through the needle cannula causes the fluid activation material to deform, such as through expansion, thereby releasing the shielding member from the first position and allowing a drive member to bias the shielding member toward the second position.

An apparatus for controlling a vapour generating device, which generates vapour through use of a consumable, includes a data storage medium and a communication means for communicating with the device. The data storage medium is arranged to store data associated with control of activation of the device and data associated with control of the vapour generating device in use. The communication means communicates with the device such that, in use, both activation and operation of the device can be controlled based on the stored data.
