Abstract
A fluid handling module that is removably engageable with a bodily fluid analyzer is provided. The module may comprise a fluid handling element, and a fluid component separator that is accessible via the fluid handling element and configured to separate at least one component of a bodily fluid transported to the fluid component separator. The fluid handling element may have at least one control element interface.
Claims22
A cassette for use with a fluid analysis system, the cassette comprising:
- (i) a housing;
- (ii) a fluid handling network comprising:
- a patient end configured to be placed in fluid communication with a bodily fluid of a patient;
- and
- one or more fluid passageways configured to transport the bodily fluid from the patient end through the fluid handing network;
- (iii) a fluid interface comprising:
- a first fluid probe movable between an abutting position and a separated position, wherein the first fluid probe is in fluid communication with the one or more fluid passageways and is configured for injection and/or removal of fluid;
- and
- a second fluid probe movable between an abutting position and a separated position, wherein the second fluid probe is in fluid communication with the one or more fluid passageways and is configured for injection and/or removal of fluid;
- and
- (iv) a sample element that comprises a first port, a second port, and a sample chamber, the first port configured to receive the first fluid probe when the first fluid probe is in the abutting position, the second port configured to receive the second fluid probe when the second fluid probe is in the abutting position, the sample chamber configured to hold a sample portion of the bodily fluid, wherein the sample chamber is in fluid communication with the first port and with the second port so as to receive the sample portion of the bodily fluid therefrom, and wherein the sample element is disconnected from the fluid handling network when the first fluid probe and the second fluid probe are in the separated positions.
A disposable cassette with an integrated sample conditioning and analysis element for use with a non-disposable analyzer, the cassette comprising:
- a fluid handling network having an analysis fluid input;
- a housing configured to contain the fluid handling network, prevent fluid from undesired contact with the non-disposable analyzer, and allow hygienic disposal of a fluid-contacting object comprising the disposable cassette;
- and
- a sample conditioning and analysis element configured to:
- receive a sample portion of the analysis fluid from the fluid handling network, wherein the fluid handling network is configured to avoid contamination of the analysis fluid while delivering the analysis fluid to the sample conditioning and analysis element;
- de-couple from the housing for sample conditioning;
- and
- position the sample portion to provide the non-disposable analyzer access to the sample portion of the analysis fluid for analysis thereof.
A fluid handling cassette for use with a fluid analysis system, the cassette comprising:
- a fluid handling network configured to transfer bodily fluid of a patient to the cassette when in use with the fluid analysis system;
- and
- a rotatable rotor configured to engage with a drive of the fluid analysis system to rotate the rotor, the rotor comprising:
- a bypass;
- and
- a sample element configured to hold a sample portion of the bodily fluid for analysis by the fluid analysis system;
- wherein the bypass and the sample element are engageable with the fluid handling network by rotation of the rotor to selectively engage the bypass or the sample element with the fluid handling network.
