Abstract: Disclosed herein are systems, methods, and a targeted temperature management (TTM) pad to facilitate thermal energy transfer between TTM fluid and a patient. The TTM pad includes a pad portion for placement on the patient and a fluid delivery conduit. The fluid delivery conduit can include a delivery conduit connector at a proximal end thereof and a fluid return conduit extending away from the pad portion. The fluid return conduit can include a return conduit connector at a proximal end thereof, and a connector coupled to a distal end of each of the fluid delivery conduit and the fluid return conduit. The connector can include a membrane configured to cover openings of both of the fluid delivery conduit and the fluid return conduit or includes multiple membranes, wherein the one or more membranes can include a piercing corresponding to each of the fluid delivery conduit and the fluid return conduit.

Abstract: A sealing member for providing a seal between fluid connectors includes a tubular member defining a lumen extending between a first end and a second end. The tubular member may receive a first connector via the first end and a second connector via the second end, and includes an annular wall extending between a first annular portion adjacent the first end and a second annular portion adjacent the second end. The first annular portion may engage the first connector, and the second annular portion may engage the second connector. When a pressure within the lumen is negative, atmospheric acting inward on the annular wall compresses the sealing member to define a contact force between the second annular portion and the second connector sufficient to define a fluid seal between the sealing member and the second connector.

Abstract: A targeted temperature management (TTM) system includes a TTM module configured to provide a TTM fluid and a pad configured to facilitate thermal energy transfer between the TTM fluid and a patient. The system includes a fluid delivery line (FDL) with a hub at the distal end of the FDL. The pad includes a connector including a flapper valve configured to alternate between open and closed positions based on whether the connector is coupled with the FDL hub. The flapper valve in the closed position covers openings of each of the fluid delivery conduit and fluid return conduit when the connector is uncoupled from the FDL hub. The flapper valve is configured to deform into the open position upon coupling of the connector and the FDL hub thereby establishing fluid communication therebetween.

Abstract: Disclosed herein is a system for performing urinalysis of transurethral patients. The system includes a tubing set to receive urine from a urethral catheter. A detector assembly is operatively coupled between the tubing set and a urinalysis module coupled. The system can perform urinalysis of a urine sample disposed within the tubing set and render urinalysis information on a display of the module. Also disclosed is a method of performing urinalysis that can include operations of: (i) placing a urine sample within a cuvette of a urinalysis system, the cuvette including a lumen extending between an inlet and an outlet; (ii) projecting coherent light into the sample; (iii) collecting output light exiting the sample; (iv)extracting urinalysis data from the collected light; and (v) rendering urinalysis results on a display of the system.

Abstract: Disclosed is a wireless instrument tracking system. The wireless instrument tracking system is used for determining the location of at least one point relative to the instrument in a three-dimensional space relative to a three-dimensional coordinate tracking system. Advantageously, a first wireless instrument can be placed into the optical field with the wireless instrument including a wireless receiver and at least one optical position indicator. The optical position indicator is typically light emitting diodes (18) and communicates with corresponding measurement sensors (30) across a wireless optical link. The wireless optical link is time multiplexed with repetitive time frames divided into time slots. Each LED (18) emits an infrared signal or flashes in a respective time slot of a time frame. The measurement sensors (30) are preferably CCD cameras.

Abstract: An orthopedic exercise chamber such as a slipper including a light-weight, self-contained limb load monitor is disclosed. The limb load sensor circuit provides extended service life for the miniature power supply that is included in the slipper, thereby making the slipper suitable for out-patient use. A fluid-filled plantar chamber that supports the entire load borne by the patient's foot is connected to the sensor circuit, thereby providing improved monitoring of the load being carried by the leg or foot that must be protected from excessive loading.
