  • Publication number: 20250235652
    Abstract: A respiratory mask includes a frame and a cushion module. The frame can include a front wall having a vent and/or a gas inlet opening and a collar extending away from the front wall. The collar surrounds the vent and/or the gas inlet opening. The cushion module comprises a cushion and a housing, which is made of a material more rigid than the cushion. The housing defines a connection opening. A friction coupling selectively couples the cushion module to the frame and comprises an elastomeric friction member coupled to a portion of the housing that defines the connection opening. In some arrangements, an outer surface of the friction member is exposed when the cushion module is coupled to the frame. In some arrangements, the housing extends through the peripheral surface.

  • Patent number: 12343514
    Abstract: A drug delivery device includes a case adapted to hold a medicament container, a plunger disposed within the case and slidable from a proximal position into a distal position for delivering a medicament from the medicament container, at least one feedback mechanism that is in operative connection with the plunger. The feedback mechanism comprises a collar, a control spring biasing the collar in a distal direction, a needle shroud, operatively axially abutting the collar in a first coupled state and prevented from axially decoupling the collar by the plunger in its proximal position The plunger, when approaching the distal position during movement from the proximal position towards the distal position, is adapted to allow axial decoupling of the needle shroud from the collar, allowing for a limited axial movement of the collar relative to the needle shroud until the collar axially abuts the needle shroud in a second coupled state.

  • Publication number: 20250180424
    Abstract: A pressure gauge includes a housing and a pressure sensor. The housing includes an access, a hollow chamber, and a vent system. The housing includes a hollow bore extending therethrough. The housing also includes a first connector and a second connector that is opposite the first connector. The first connector is concentrically aligned with the hollow bore for allowing fluid to enter the hollow bore. The second connector is concentrically aligned with the hollow bore for allowing fluid to exit the hollow bore. The access is oriented generally perpendicularly to the hollow bore. The pressure sensor is positioned within the access and is recessed from the hollow bore. The hollow chamber is sized to contain the pressure sensor therein. The vent system includes an opening and a protective cover. The vent system opening is substantially concentrically aligned with the pressure sensor and the protective cover extends across the vent system opening.

  • Patent number: 12318597
    Abstract: A syringe carrier includes a housing adapted to receive a syringe having a needle encapsulated by a removable protective needle sheath, and two or more flexible arms protruding inwards in a relaxed state and adapted to couple with the syringe in a mounted position. The flexible arms are adapted to deflect radially outwards in a pre-assembled position of the syringe in the syringe carrier. In the mounted position the flexible arms are allowed to return into the relaxed state due, in part, to an axial force operating on the syringe carrier. The disclosure further relates to an autoinjector and a method of assembling the autoinjector.
