Patent ID: 8562814

Claim:
A measurement device for electrochemically analyzing an analysis sample which is collected by a sensor having an electrode terminal, the measurement device comprising: a measurement device body; a sensor holding part integrated with the measurement device body, said sensor holding part being configured to hold the sensor; a connection terminal supported by the measurement device body, and configured to contact the electrode terminal of the sensor that is held by the sensor holding part; an ejection mechanism configured to eject the sensor from the sensor holding part, the ejection mechanism including an element which pushes a front side surface of the sensor while the sensor is held by the sensor holding part with the electrode terminal of the sensor contacting the connection terminal to release the contact of the electrode terminal of the sensor with the connection terminal, the front surface of the sensor being on a front side of the sensor in a direction in which the sensor is inserted into the sensor holding part; and a brake part provided at a portion of the measurement device body, said brake part configured to contact the sensor to brake the movement of the sensor in the ejection direction while the sensor is being ejected by the ejection mechanism, wherein the brake part reduces a speed with which the sensor separates from the sensor holding part.
