Abstract: Peripheral oedema causes a swelling of the legs of a patient due to an abnormal accumulation of fluids in the interstitium of the patient. Oedema is directly related to heart diseases, kidney and liver problems and pathological conditions. As such, is a useful indicator of a person's overall health. Oedema is typically assessed by a subjective manual test administered by a medical professional. As such, an objective assessment of oedema is often difficult to make. The present disclosure concerns a device for tissue condition measurement. The device enables an objective assessment of oedema to be made, by providing to a medical professional, or a medical ancillary worker, with information useful to judge the presence of oedema.

Abstract: The present invention relates to blood analysis. In order to determine the filling level of a cartridge, a device (10) is provided that comprises a cartridge interface (14) for receiving a cartridge and a liquid level sensor (16). A cartridge position guiding arrangement is configured to engage with the cartridge for providing a six degree-of-freedom constraint to the cartridge. The liquid level sensor comprises a light source (18) and a light detector (20). The light source is configured to provide a beam of light (22) incident upon a cavity surface (24) of an optical pit (26) of a cartridge received by the cartridge interface. The light detector is configured to detect a portion (28) of the beam of light reflected from the cavity surface of the optical pit. The device is configured to determine a filling level of the optical pit based on the detected portion of the beam of light.
