Abstract: The invention provides devices and methods for sterilization/disinfection control of medical devices. In particular, a system is provided which comprises (i) an enclosure which is configured to deliver UV light for purposes of sterilization and/or disinfection; and (ii) one or more medical devices. The enclosure and medical device(s) are configured to communicate such that the system recognizes the identity of the medical device, recognizes that sterilization/disinfection has occurred, and electronically stores data related to the sterilization/disinfection of the medical device(s) within the enclosure. This data storage can occur on the medical device(s) themselves, or on a remote computer.

Abstract: Connector assemblies are provided for controlling flow in a fluid line that include an outer shell, an inner housing, and a tubular member. The inner housing is disposed within the outer shell and includes a boss disposed adjacent a first end of the outer shell. The inner housing is movable axially within the outer shell between first and second positions when a device is connected to the first end. The tubular member is carried by the inner housing and includes a fluid passage extending between a second end of the outer shell. The tubular member moves axially as the inner housing moves between the first and second positions, and cam features on the outer shell and the tubular member cause the tubular member to rotate as the inner housing moves between the first and second positions, thereby opening a fluid path between the fluid passage and the first end.

Abstract: Valves are provided for controlling flow along a fluid line that includes an outer shell and an inner housing slidably disposed therein that includes connector threads surrounding a boss on one end and a passage including a tapered region within the boss. A shaft within the valve includes a base coupled to the outer shell, a tapered sealing pin disposed within the tapered region, and a fluid passage extending through the base to outlets in the sealing pin. A connector may be threaded into the one end of the inner housing, thereby slidably engaging the connector threads, camming elements on the inner housing causing the inner housing to move helically from a closed position wherein the sealing pin engages the boss to seal the outlets and an open position wherein the inner housing is directed away from the sealing pin to open a fluid path through the valve.

Abstract: An exercise chair includes a seat; a base having one or more base supports, the one or more base supports configured to contact a support surface; a seat support supporting the seat, pivotally connected to the base, and biased upward, the seat support including a fulcrum, and wherein downward pressure on the seat by a sitting user causes the fulcrum of the seat support to contact that support surface in addition to one or more of the one or more base supports, forcing the user to maintain a balanced posture on the seat in order to maintain the seat support in a vertical orientation.
