摘要： A method and apparatus are provided that interrogate, receive, and analyze full emission spectra for at least one fluorescence excitation wavelength and for at least one reflectance measurement to determine tissue characteristics. The method includes illuminating a first portion of a target tissue with optical energy, forming a first image of the target tissue, illuminating a second portion of the target tissue with optical energy, performing spectroscopic measurements on optical energy reflected and/or emitted by the target tissue upon illumination of the second portion of the target tissue with optical energy, and determining tissue characteristics of the target tissue based on the results of the spectroscopic measurements. The apparatus and system include a base unit having illumination, detection and control sub-units, the illumination sub-unit providing illumination optical energy for illuminating a target tissue and the detection sub-unit detecting tissue characteristics of a target tissue, a separate tissue interface unit, and a pathway coupling the base unit and the tissue interface unit. The system and apparatus may also include a tissue interface unit configured to perform spectroscopic measurements on a target tissue, a docking unit configured to support the tissue interface when not in use, the docking unit including an illumination source and a processor that processes spectrographic measurements results received from the tissue interface unit, and a pathway coupling the docking unit and the tissue interface unit.

摘要： A fluid jet blood sampling system and method for obtaining a blood sample from a mammal, utilizes a fluid jet from a disposable jet nozzle to perforate at least the epidermis of the skin and to break at least one blood vessel, thereby allowing a quantity of blood to accumulate on the skin surface of the mammal. A cowling prevents contamination of the local environment with excess fluid, blood, etc. A drying unit may be provided to remove excess fluid, blood, etc. from the skin within the cowling. A sample of blood may be transferred to a test strip, or a collection unit may be used to collect and contain a blood sample from the mammal.

摘要： A disposable calibration device is used to calibrate a measurement system which transmits radiation or acoustic waves to a material or tissue in order to effect measurements. The disposable calibration device includes a structure with a window through which the radiation or acoustic waves can be transmitted, as well as a removable calibration target arranged on the window and capable of returning a portion of the radiation or acoustic waves for calibrating the measurement system. The removable calibration target can be peeled from window to allow a measurement to be made on the material or tissue. Once a measurement is complete, the disposable calibration device can be discarded and a new calibration device can be inserted on the measuring system.

摘要： A system and method for calibrating a measurement instrument prior to making a measurement on a material or tissue includes utilizing a removable calibration device to calibrate the instrument, then removing a target portion of the calibration device so that a measurement may be performed. The calibration device may include an index matching agent, such as a gel, that is to be interposed between the patient's skin and an output end of the measuring instrument. A method embodying the invention may include making a bilirubin concentration measurement on a skin of a patient by measuring the amplitude of light reflected from the patient's skin at first and second wavelengths indicative of a blood content of the patient's skin, and measuring the amplitude of reflected light at a third wavelength indicative of an uncorrected bilirubin concentration, then calculating a corrected bilirubin concentration based on the three measurements. The method may also include taking measurements at fourth and fifth wavelengths indicative of a melanin content of the patient's skin, and calculating the bilirubin concentration based on the fourth and fifth measurements.
