Disposable calibration target |
摘要 |
A combined infection shield and calibration or reference target for use with a measuring instrument includes a removable calibration/reference layer. The removable calibration/reference layer has predetermined optical characteristics that can be utilized to calibrate or reference the instrument. When the calibration/reference layer is removed from the remaining portions of the device, the portion of the calibration/reference layer having the predetermined optical characteristics is irrevocably altered such that the calibration/reference layer cannot be reused. The combined infection shield and target may be attached to a shield holder, which in turn is attached to an instrument. Alternatively, the infection shield and target may be attached directly to an instrument. The target may include a calibration/reference layer having a reduced strength portion which causes the target to tear or separate in a predetermined manner. Also, a double-sided adhesive layer with a gap may be used to attach the target to the remaining portions of the device, wherein the gap is arranged in a predetermined orientation with the reduced strength portion to aid tearing or separation of the target in a predetermined manner. The device may also include a cutter for causing the calibration/reference layer to tear or separate in a predetermined manner when the calibration/reference layer is removed from other portions of the device.
