Abstract
A medical waste collection system includes a medical waste collection device for providing suction at a surgical site, and a manifold releasably couplable to the medical waste collection device. The manifold defines a pathway through which the medical waste collection device is configured to provide suction to the surgical site. The medical waste collection device is configured to control activation of suction based on a proper manifold being present.

A medical waste collection system comprising:
- a medical waste collection device for providing suction at a surgical site;
- a manifold releasably couplable to the medical waste collection device and defining a pathway through which the medical waste collection device is configured to provide the suction to the surgical site, the manifold including an RFID tag including a first memory bank storing an identifier for the RFID tag, a second memory bank for storing electronic identification data for the manifold, and a third memory bank for storing user data, the third memory bank including a plurality of memory blocks with one or more first memory blocks of the plurality of memory blocks being locked in a permanent read-only state and one or more second memory blocks of the plurality of memory blocks not being locked in the permanent read-only state according to a predefined lock pattern for verifying the RFID tag by the medical waste collection system;
- and
- a controller of the medical waste collection device that is configured to, responsive to the manifold being coupled to the medical waste collection device:
- determine that the one or more first memory blocks each exhibits a behavioral characteristic consistent with the permanent read-only state and the one or more second memory blocks each does not exhibit the behavioral characteristic of the permanent read-only state;
- and
- enable operation of the medical waste collection device to provide the suction at the surgical site responsive to determining that the one or more first memory blocks each exhibits the behavioral characteristic consistent with the permanent read-only state and the one or more second memory blocks each does not exhibit the behavioral characteristic of the permanent read-only state.
A method for preparing an RFID tag for a manifold configured to be coupled to a vacuum inlet integral with a medical waste collection device to provide suction at a surgical site through the manifold, the method comprising:
- obtaining a memory device for the RFID tag, the memory device comprising a first memory bank storing an identifier for the RFID tag, a second memory bank for storing electronic identification data for the manifold, and a third memory bank for storing user data, the third memory bank comprising a plurality of memory blocks;
- writing to the third memory bank a rover type datum corresponding to the medical waste collection device, a first hash digest generated based on the rover type datum, use history data for the manifold, and a second hash digest generated based on the use history data for the manifold;
- and
- locking one or more first memory blocks of the plurality of memory blocks of the third memory bank in a permanent read-only state such that one or more second memory blocks of the plurality of memory blocks of the third memory bank are not locked in the permanent read-only state according to a predefined lock pattern for verifying the RFID tag by the medical waste collection device.
An RFID tag for a manifold configured to be coupled to a vacuum inlet integral with a medical waste collection device to provide suction at a surgical site through the manifold or a manifold including an RFID tag, the RFID tag comprising:
- a memory device storing data for being read by the medical waste collection device when the manifold is proximate the medical waste collection device to control actuation of the medical waste collection device, the memory device comprising:
- a first memory bank storing an identifier for the RFID tag;
- a second memory bank storing electronic identification data for the manifold;
- and
- a third memory bank comprising a plurality of memory blocks with one or more first memory blocks of the plurality of memory blocks being locked in a permanent read-only state and one or more second memory blocks of the plurality of memory blocks not being locked in the permanent read-only state according to a predefined lock pattern for verifying the RFID tag by the medical waste collection device.
