Fluid-transfer collection assembly and method of using the same
First Claim
1. A fluid transfer and mixing collection assembly, comprising:
- a base;
a test media carried by the base;
an inlet for receiving a first fluid, the inlet including an inlet check valve;
an outlet including an outlet check valve;
a bladder carried by the base between the inlet and the outlet and including an interior with a second fluid therein; and
a depressable, flexible member carried by the base between the inlet and the outlet and including an interior, a membrane separating the interior of the bladder from the interior of the flexible member, the flexible member including an exterior surface, an interior surface, and a pointed member extending from the interior surface of the flexible member, the flexible member depressable to cause the pointed member to rupture the membrane, releasable to draw the first fluid into the interior of the flexible member through the inlet check valve to mix with the second fluid, and depressable again to pump the mixed first and second fluids out of the interior of the flexible member through the outlet check valve and be transferred to the test media.

Abstract
A fluid transfer and mixing collection assembly includes a base and a test media, an inlet check valve, and an outlet check valve carried by the base. A bladder containing a fluid and a flexible member are carried by the base between the check valves and are separated by a membrane. The flexible member is depressable to cause a pointed member extending from the flexible member to rupture the membrane, releasable to draw a sample fluid into an interior of the flexible member through the inlet check valve to mix with the fluid from the bladder, and depressable again to pump the mixed fluids out of the interior of the flexible member through the outlet check valve and be transferred to the test media.

5. A method of using a fluid transfer and mixing collection assembly, comprising:
-
providing a fluid transfer and mixing collection assembly including a base, a test media carried by the base, an inlet for receiving a first fluid, the inlet including an inlet check valve, an outlet including an outlet check valve, a bladder carried by the base between the inlet and the outlet and including an interior with a second fluid therein, and a depressable, flexible member carried by the base between the inlet and the outlet, the flexible member including an interior, a membrane separating the interior of the bladder from the interior of the flexible member, the flexible member including an exterior surface, an interior surface, and a pointed member extending from the interior surface of the flexible member;
depressing the flexible member to cause the pointed member to rupture the membrane;
releasing the flexible member to draw the first fluid into the interior of the flexible member through the inlet check valve to mix with the second fluid;
depressing the flexible member to pump the mixed first fluid and second fluid out of the interior of the flexible member through the outlet check valve and be transferred to the test media. - View Dependent Claims (6, 7, 8)

9. A fluid-transfer collection assembly, comprising:
-
an inlet for receiving one or more fluids, the inlet including an inlet check valve;
an outlet including an outlet check valve;
a test media; and
a depressable, flexible member located between the inlet and the outlet and including an interior, the flexible member depressable to cause one or more fluids to exit the interior of the flexible member through the outlet check valve and be transferred to the test media and releasable to draw one or more fluids into the interior of the flexible member through the inlet check valve. - View Dependent Claims (10, 11, 12)
