A flexible patient interface structure includes a posterior portion with at least one thin flexible membrane configured to form a seal with the patient's face in use. A wall thickness of the posterior portion is varied. An anterior portion of the flexible patient interface forms a chamber with the posterior portion and has a central gas washout vent region. A wall thickness of the anterior portion is thicker at the central gas washout vent region than at other adjacent regions. First and second laterally extending protrusions are configured to receive the breathable gas from an air delivery tube or air delivery tube connector. The central gas washout vent region is located between the first and second laterally extending protrusions and comprises an array of vent openings. Each of the first and second laterally extending protrusions terminates at a distal end that is furthest from the other laterally extending protrusion.

Respiratory mask

A patient interface is configured to deliver pressurized breathable gas to a patient's airways and includes a flexible cushion forming at least a portion of a plenum chamber. A pair of flexible receptacles are integrally formed with the flexible cushion and are formed on opposite lateral sides of the flexible cushion. Each flexible receptacle includes an inner wall that forms an opening configured to receive an air delivery tube and an outer wall that is radially offset from the inner wall. The outer wall extends laterally beyond the inner wall on a posterior side of the flexible receptacle and does not extend laterally beyond the inner wall on an anterior side of the flexible receptacle. The patient interface further includes a gas washout vent, a support structure that is attached to and is more rigid than the flexible cushion, and a pair of headgear connectors located on opposing lateral sides of the support structure.

A respiratory mask for use with a patient, and that is suited for use with children, includes a flexible cushion arranged to interface with and deliver air to the patient's nose. The cushion has a tube connection portion at one or both sides adjacent the patient's nares, the tube connection portion being arranged to connect to an air delivery tube. This location, plus the very low profile of the mask, allows a patient (e.g. an infant) to sleep on their face more comfortably. A more rigid support structure adjacent the cushion is provided to stabilize the cushion and prevent it from collapsing. Headgear is also provided and arranged for releasable attachment to the support structure.

A replaceable needle assembly is provided for a retractable, prefilled syringe comprising a barrel having a mounting member and a plunger, whereby the retractable needle can be replaced by a user without affecting the retraction mechanism. The replaceable needle assembly comprises a needle fitted to a retractable needle mount and a needle retainer. The needle mount is removably, screw-threadedly mountable to the mounting member of the barrel. The needle retainer comprises a plurality of fingers that releasably engage the retractable needle to thereby prevent inadvertent retraction of the retractable needle before engagement by the plunger. The plunger comprises a plunger seal comprising an outer member and an inner member that engages the needle for spring-driven retraction. At the end of retraction, a lock is formed between the plunger and barrel to prevent re-use of the syringe.

Vaccination syringe

A respiratory mask assembly for use with a patient, and that is suited for use with children ranging in age from about 2-7 years, includes a flexible patient interface structure arranged to interface with and deliver air to the patient's nose, the patient interface structure including cylindrical protrusions extending from respective opposite sides of the patient interface structure adjacent the patient's nares; a frame configured to support the patient interface structure, the frame including a pair of cylinders, each cylinder configured to receive a respective cylindrical protrusion of the patient interface structure; headgear arranged for releasable attachment to the frame; an air delivery tube connected to either one of the cylindrical protrusions; and a plug connected to the other one of the cylindrical protrusions.

Cushion for respiratory mask

An apparatus for delivering a flow of breathable gas to a patient for the treatment of Sleep Disordered Breathing (SDB) that is less obtrusive includes a nasal cannula, cannulae (), prongs, or pillows and may be sealed or unsealed with the nares of the patient in use. The cannula, pillows or prongs may be positioned on the face of the patient by a headgear (). The cannula, pillows or prongs may be smaller, lighter, and/or less visible than other nasal cannula, cannulae, pillows or prongs and may therefore be less obtrusive to the patient.

A replaceable needle assembly is provided for a retractable syringe comprising a barrel and a plunger, whereby the retractable needle can be replaced by a user without affecting the retraction mechanism. A mounting member is removably mountable to the barrel by way of a screw-thread connection and a needle mount is removably coupled to the mounting member. A needle is mounted to the needle mount. The barrel comprises a needle mount retainer that comprises a plurality of fingers that engage the retractable needle mount to prevent inadvertent retraction. The plunger comprises a collapsible seal which maximizes the efficiency of fluid delivery prior to the plunger engaging the retractable needle mount for retraction. An initially compressed spring decompresses to drive retraction of the plunger and the engaged needle mount. A lock formed between the plunger and barrel prevents further use of the plunger after retraction.
