Abstract: A mask adapted for delivering pressurised air to a user, the mask comprising: an endoskeleton of a first resilient material encapsulated to a lamina of a second resilient material forming a mask body with a cavity. The second resilient material is more flexible than the first resilient material. The lamina having a face contactable skirt portion extending away from the endoskeleton perimeter. The skirt portion comprises an outer layer and an inner layer for providing variable contoured thickness to outer lamina segments of the face contactable portion.

Abstract: 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.

Abstract: A pressure sensing device including an elongate housing configured to be at least partially inserted into a user, and that defines an external surface having a proximal end and a distal end defining a longitudinal axis therebetween. The device includes a first pressure sensor, configured to sense pressure applied to a first portion of the external surface and to convert the sensed pressure to first pressure data, and a second pressure sensor, configured to sense pressure applied to a second portion of the external surface and to convert the sensed pressure to second pressure data. Sensor is spaced, along the longitudinal axis, toward the distal end from sensor.

Abstract: A syringe manifold for a fluid injector assembly includes a middle body member defining an upper cavity and a lower cavity, the middle body member defining at least one fluid path in an upper surface of the middle body member and at least one fluid path in a lower surface of the middle body member, the middle body member defining at least two ports extending through the middle body member, the middle body member comprising an outlet for connection of the syringe manifold to at least one fluid delivery device; a lower body member received within the lower cavity of the middle body member, the lower body member comprising at least one connector for connection of the lower body member to a syringe assembly; and an upper body member received within the upper cavity of the middle body member.

Abstract: 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.

Abstract: 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.
