This invention relates to a patient interface and component parts which may be integrated or form a part of an assembled interface for use by a user. In various embodiments, the component parts may include: a component may be provided as a clip for supporting a gas supply tube to the interface; a buckle may be provided at an end of a headgear strap for releasable attachment to the interface; a manifold part of a patient interface may be attachable to the interface in a manner allowing for adjustment or re-orientation such that an associated gas supply conduit is re-routed to be to a left- or a right-side of the interface (or user); one or a pair of support side arms of the interface may be configured to be twisted or bent so as to more comfortably accommodate the shape of a user's face upon which they are to be located in use; parts of a manifold at the connection of a gas supply tube to the interface may be configured to be of a multi-part manifold assembly.

A closing device for releasably connecting a first part to a second part. The closing device may have a first closing unit comprising a spherical engaging part, and a first retaining device for attaching the first part. The closing device also may comprise a second closing unit which has a second retaining device for attaching the second part, and a cut out, which is delimited by a wall, for receiving the spherical engaging part, where the cut out has an opening for inserting the spherical engaging part. A sliding unit may be located in the cut out, said sliding unit being preloaded in the direction of the opening, and the sliding unit can be displaced into an open position and a closed position. In the open position of the sliding unit, the spherical engaging part may be received in the cut out.

A locking slide clip includes a C-shaped body and a door. The C-shaped body defines an opening in communication with a slot. The door is pivotably engaged with the C-shaped body opposite the slot and includes a protrusion.

A buckle may include male and female parts. In a case (A) where only the female part is attached to a slider of a slide fastener, the male part includes: a pair of arms respectively provided with locking protrusions; and a connecting rod connecting respective base ends of the pair of arms. The connecting rod is configured to curve away from a space between the locking protrusions of the arms when the arms are bent such that the locking protrusions approach one another. In a case (B) where the male part is attached to a slider of a slide fastener, the male part includes: a slider-holding frame configured to hold the slider; and a pair of arms that extend in the same direction from the slider-holding frame and are respectively provided with locking protrusions. The slider-holding frame includes a frame portion protruded into a space between the pair of arms toward a space between the locking protrusions.

A clip adapted for use with an elongate strap for forming a tourniquet including first and second parts adapted to be connected to the strap, the first and second parts adapted to be releasably connected together to form a closed loop. The second part is adapted to movable along the strap and has an open passageway through which the strap passes. Integrally formed first and second elongate walls define at least part of the passageway and first and second grip portions for gripping the strap. The second wall is mounted for rotation about a transverse axis so as to move the grip portion of the second wall toward or away from the first grip portion.

A buckle according to the present invention has two opposing ends that are removably attached to each other using a locking system. On one end of the buckle, the locking system includes two opposing locking pins coupled to a spring that is fully enclosed and protected from external elements. On the other end, corresponding rivets or pin casings with plungers are operable to receive the locking pins and lock the two ends together or push the pins out of the casings to release the buckle. The buckle may also include a plug that is removably attached to the adjustable loop end and allows the central bar of the adjustable loop end to be removed without deforming the central bar. Alternatively, each end of the buckle may include self-aligning tabs that guide the ends of the buckle for fastening and aid in the stability of the buckle.

This application relates to a fastener, a fastener monitoring system, and a child carrier. The fastener includes a male buckle, a female buckle, and a control circuit. The fastener has a locked state in which the male buckle is snap-fitted to the female buckle and an unlocked state in which the male buckle is separated from the female buckle. The control circuit is disposed on the male buckle and/or the female buckle. The control circuit includes a wireless communication module. In response to the fastener being in the locked state, the control circuit controls the wireless communication module to transmit a wireless signal.

The invention relates to a novel incendiary device with a fire starter and a quick release slide buckle wherein sparking and ignition means reside in the buckle apparatus, and which buckle may be attached to clothing, backpacks or any other item a quick release slide buckle may be utilized. One portion of the buckle houses a sparking and combustible material, and the other is a mating side of a quick release buckle. Adding a fire starter to a quick release buckle is a novel tool for any outdoor activity that requires fire ignition.

An ambidextrous, adjustable cross-body strap comprising a plurality of variably sized pockets, a buckle and universal interlocking keyring system for added user security. The cross-body strap can be worn under or over a shirt or jacket. In one embodiment, it is water resistant or waterproof. In one embodiment, the cross-body strap has interchangeable clasps and hooks that are stored in one of the plurality of pockets built into the strap. The interchangeable clasps hook and carabiners can be used separately or in combination with the universal interlocking rings to self-attach or alternatively attach to any messenger bag, gym bag tactical clips, such as a keyring holder, straps with snaps or briefcase.

A respiratory effort belt connector system and method for securing the belt to the user's body is provided. The respiratory effort belt connector system includes a belt coupled to the grip of a connector and a receptacle housing. The receptacle housing having a receptacle opening, a guide notch, a locking recess, and a locking lug located above the locking recess. The connector includes a barrel having an end configured to be inserted into the receptacle opening and a locking bar coupled to the barrel. The locking bar is configured to be aligned and inserted into the guide notch and then rotated into the locking recess where the locking bar/connector are retained by the locking lug of the receptacle. A connector neck couples the grip, which is configured to be accessible, to the barrel.
