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.

Abstract: An integrated testing device and method are disclosed. The device includes an integral reservoir for a test fluid, and an actuator, so that the test fluid can be dispensed to facilitate the test.

Abstract: 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.

Abstract: A mechanism for releasing a mask from a patient's face includes a frame part including a male connection and a frame engagement portion for engaging a cooperating portion on a frame of the mask. A headgear part includes a female connection that is adapted to receive the male connection when the frame part is inserted into the headgear part, and a headgear engagement portion for engaging a cooperating portion on headgear of the mask. A cord has one end secured to the male connection, such that when the cord is pulled by the patient the male connection disengages from the female connection and consequently the frame part separates from the headgear part releasing the mask from the patient's face. A method of releasing a mask from a patient's face includes pulling a cord away from a frame of the mask to release a latch of the mask frame from a latch receiving portion of a headgear of the mask to release the latch from the latch receiving portion.
