Abstract: A catheter assembly configured for use with a medical device is provided herein. The catheter assembly can comprise a catheter hub having an interior chamber and a valve located in the interior chamber. The valve can comprise a distal portion, a proximal portion, and a sidewall extending therebetween to define a valve interior. The valve can include a barrier layer having a concave shape that extends in the valve interior from the sidewall at the distal portion. The barrier layer can have at least one slit extending therethrough that is in a normally closed configuration to prevent a fluid from passing through the barrier layer. The catheter assembly can further comprise a sealing ring located circumferentially at a distal end of the valve distally to the barrier layer. The sealing ring can form a seal between the valve and the interior chamber at the distal end.

Abstract: An example device includes a user interface positionable at a room, a network interface to communicate with a computer network, a processor connected to the user interface and the network interface. The processor outputs at the user interface a user-interface element associated with a physical condition of the room, receives a selection of the user-interface element from an occupant of the room, and, in response to the selection of the user-interface element, transmits to a server via the network interface a service request related to the physical condition of the room.
