Abstract: A rotary planar peristaltic micropump (RPPM) includes an actuator having a shaft engaged with a motor such that activation of the motor causes the shaft to rotate, and a bearing assembly engaged with the shaft. The bearing assembly has a bearing cage defining a plurality of spaced-apart openings thereon, and a plurality of rolling-members accommodated in the plurality of spaced-apart openings of the bearing cage, such that when the shaft rotates, the plurality of rolling-members of the bearing assembly rolls along a circular path. The RPPM also includes a fluidic path in fluidic communication with first and second ports. The fluidic path is positioned under the actuator and coincident with the circular path, such that when the shaft of the actuator rotates, the plurality of rolling-members of the bearing assembly rolls along the fluidic path to cause a fluid to transfer between the first and second ports.

Abstract: A platform for cultivation, maintenance, and/or analysis of one or more bio-objects includes one or more integrated bio-object microfluidics modules. Each integrated bio-object microfluidics module is configured to cultivate, maintain, analyze and/or mimic functionalities of a respective bio-object, and includes one or more on-chip pumps; a plurality of fluidic switches; and a microfluidic chip in fluid communication with the one or more on-chip pumps and the plurality of fluidic switches, having at least one chamber for accommodating the bio-object and a plurality of fluidic paths connecting the at least one chamber, the one or more on-chip pumps and the plurality of fluidic switches, and a power and control unit adapted for selectively and individually controlling the one or more on-chip pumps and the plurality of fluidic switches for performing bio-object microfluidics functions.

Abstract: A position-independent fluid trap for separating at least a portion of a first fluid of a first density entrained within a flow stream of a second fluid of a second density flowing through a fluid circuit. The trap is connectable within the fluid circuit to a first length of tubing defining an inlet line and to a second length of tubing defining an outlet line, and includes a housing enclosing an interior chamber having a geometric extent of a given volumetric capacity. An inlet port is provided to open in fluid communication with the interior chamber and to be couplable to the inlet line. An outlet tube is provided to extend from a proximal end couplable to the outlet line to a distal end disposed within the housing and opening in fluid communication with the interior chamber. Within the interior chamber, the first and second fluid are separated at an interface into a first and second fluid component according to the relative densities thereof.

Abstract: Liquid incursion into the gas analyzer or monitoring components of a gas analyzer of a variety employed in medical practice is prevented by a sequence of components performing under computer control. A liquid detector is positioned immediately downstream of the liquid separator/trap of the apparatus to detect any failure of that separating system. Should an incursion occur, the output of the detector will cause a safety valve to block further passage of materials into the monitoring components. The removable separator/trap components are monitored by interlock sensors. Upon appropriate signaling of such removal, a purging valve is actuated to employ atmospheric air made available by the removal of the separator/trap unit to purge the encroaching liquid from the forward components of the analyzer assembly.

Abstract: Blood is stored under refrigeration at a temperature of about 4.degree. C. When it is utilized on a relatively rapid basis within a surgical theater it is transported by tubing through a blood warming apparatus which, while warming the blood, causes an outgasing of entrained air. This air is trapped in an air trap receptacle having a drip chamber within which a gas-blood interface is developed. To assure that the capacity of the trap is not exceeded, an improved technique of gas removal and interface level setting is provided wherein access is achieved essentially through the entrance region of the gas trap receptacle.
