Abstract
A blood parameter measurement cassette or other device is configured to control incidental liquid discharged during the device's calibration process. The cassette includes optical sensors which are chemically responsive to blood constituents and require calibration with a blood parameter monitoring device prior to use in a medical procedure. During the calibration process, an incidental amount of a liquid may be expelled from the cassette. The present invention is directed towards controlling the expelled liquid by absorbing it using an absorbent material disposed on the exterior of the cassette's main body. The absorbent material thereby prevents the liquid from causing detrimental effects to the monitoring and calibration equipment used in conjunction with the cassette. The scope includes additional embodiments wherein the inventive concept is applied to other fluid-handling medical devices that require venting of gases.
