Abstract
A method and system for processing a sample in a fluid is provided. An assembly comprising a cap prefilled with a fixative solution, a valve, and a container for storing a tissue sample are provided. The valve is adapted to be situated between the cap and the container such that fluid can flow from the cap into the container when the assembly is upright, but the fluid cannot backflow from the container to the cap when the assembly is horizontal or inverted.
Claims18
A system comprising:
- (a) a first container comprising a first chamber;
- (b) a second container comprising a second chamber;
- (c) a valve disposed between the first chamber and the second chamber, wherein the valve is movable between at least an open configuration and a closed configuration, wherein the valve is in the closed configuration when no first force is applied to the valve, and wherein the valve is in the open configuration when the first force is continuously applied to the valve;
- and
- (d) an actuator moveable between at least a disengaged position and an engaged position, wherein when in the engaged position (i) the actuator is in contact with at least a portion of the valve;
- and (ii) at least a portion of the actuator is disposed within the second chamber.
3 more elements
A system comprising:
- (a) a container comprising a first chamber and an integral second chamber;
- (b) a valve assembly disposed between the first chamber and the second chamber, wherein the valve assembly comprises (i) a seal, and (ii) a resilient mechanism, wherein the valve assembly is movable between at least an open configuration and a closed configuration, wherein the valve assembly is in the closed configuration when the resilient mechanism applies a first force against the seal, and wherein the valve assembly is in the open configuration when an actuator applies a second force against the seal which is greater than the first force;
- and
- (c) an actuator moveable between at least a disengaged position and an engaged position, wherein when in the engaged position the actuator exerts the second force onto at least a portion of the seal.
1 more element
A system comprising:
- (a) a container comprising a first chamber and an integral second chamber;
- (b) a duckbill valve disposed between the first chamber and the second chamber, wherein the duckbill valve is movable between at least an open configuration and a closed configuration, wherein the duckbill valve is in the closed configuration when no first force is applied to the valve, and wherein the duckbill valve is in the open configuration when the first force is continuously applied to the valve;
- and
- (c) an actuator moveable between at least a disengaged position and an engaged position, wherein when in the engaged position the actuator exerts the first force onto at least a portion of the duckbill valve.
