The present invention relates to a haematology device for use in detecting blood within the skin of a mammal, notably a human being, which device comprises: a) a hand portable housing (1) adapted to be passed over the skin of the mammal; b) an infra-red signal emitter (10) operatively associated with the housing (1) and adapted to project a near infra-red signal having a wavelength of from 700 to 2,500 nanometres onto the skin of the mammal; c) a sensor (11) in operative association with the emitter (10) and adapted to detect the near infra-red signal re-radiated from the skin of the mammal; d) comparator means for comparing the signal emitted with the signal detected by the sensor to monitor the proportion of the emitted signal which is absorbed and/or scattered by the skin of the mammal; and e) means (12) to emit a signal to indicate when the proportion of the emitted signal which is absorbed and/or scattered is above or below a predetermined level. The invention also provides methods for monitoring blood analytes by using a non-invasive pathological device in association with the device of the invention; and a method for locating abnormalities in the skin using the device of the invention. |
