Abstract
An apparatus for handling a patient's blood during a first medical use which is convertible for a second medical use comprises a first device, for adapting the reservoir for use during a first medical use and a second device for adapting the reservoir for a second medical use after the first medical use. A lever pivotally mounted on the apparatus, engages at least one of the devices so that pivoting the lever causes the devices to move, moving the first device out of its operative position and moving the second device into its operative position. A lock for the lever locks the devices in place, and a valve mechanism automatically selects a proper outlet.

An apparatus for handling a patient's blood during medical procedures which is convertible for multiple medical uses, the apparatus comprising:
- a reservoir;
- a port in the reservoir comprising at least one opening;
- a first block alignable with the port for adapting the reservoir for a first medical use, the first block including first connection means for connecting tubing to the first block in fluid communication with the port when the first block is aligned with the port;
- a second block, separate from the first block, alignable with the port, for adapting the reservoir for a second medical use, the second block including second connection means for connecting tubing to the second block in fluid communication with the port when the second block is aligned with the port;
- means for mounting the first and second blocks on the reservoir with the first block initially aligned with the port to allow the reservoir to be used for the first medical use, the mounting means allowing the first block to be moved out of alignment with the port and the second block to be moved into alignment with the port to allow the reservoir to be used for the second medical use;
- and
- rack-and-pinion lever means for moving the first block out of alignment with the port and for moving the second block into alignment with the port.

- mounting means for movably mounting the first and second blocks on the reservoir so that the first block can be aligned with the port to allow the reservoir to be used for the first medical use, and so that the first block can be moved out of alignment with the port and the second block to be moved into alignment with the port to allow the reservoir to be used before or after the first medical use for a second medical use;
- and
- a lever pivotally mounted on the reservoir and having a pinion that engages at least one of the first and second blocks to move the first and second blocks when the pinion rotates as the lever is pivoted.
