Disclosed are a measurement device and a puncture device that prevent thermal loss and enable decreased cost in laser units. A laser unit () of a measurement device () is equipped with a lens barrel (), a laser rod () disposed inside the lens barrel (), a flash lamp () which is disposed opposite the laser rod () inside the lens barrel () and in which an inert gas is sealed inside a hard glass tube (), and supports (), which are made from a material with thermal conductivity of 100 W/(mK) or more, at least parts of which are disposed outside of the lens barrel (), and which support the circumferential surface of the hard glass tube () in a housing.

Measurement device and puncture device

A blood test device () ensuring successful measurement wherein fingers scarcely slip out from the blood test device and blood never sticks to other sites in the course from the puncture of the patient's skin to the completion of the blood test. This blood test device () comprises a cartridge () in which sensors () pooling blood oozing out from the punctured skin are stored in a layered state, a transport unit transporting a single sensor sheet () from the inside of the cartridge () to the outside, a holder () holding the transported sensor (), a laser emitting unit () puncturing the skin in the state where the sensor () is held by the holder (), and a pump () keeping the inside of the holder () and the inside of the cartridge () under negative pressure.

Blood test device

A sensor holder comprises a sensor mounting part having a first face on which a blood sensor is placed, a second face provided on the opposite side from the first face, and a through-hole that goes from the first face to the second face and is large enough to allow a laser beam to pass through; a finger holding part that is provided on the second face and surrounds the through-hole, and a grip that sticks out from the blood testing device when the sensor holder is mounted to the blood testing device.

Sensor holder, holder unit in which blood sensor is mounted to the sensor holder, and blood testing device to which the holder unit is mounted

A blood testing device in which a blood sensor does not contaminate a piercing section when discarded. The blood testing device () is provided with the piercing section () having an upper holder () and a lower holder (), and also with a connector (). In piercing operation, the connector (), the upper holder (), and the lower holder () sandwich and hold the sensor (). To discharge the sensor, the lower holder () is pivoted so as to be separated from the upper holder (), which creates a space between the lower holder () and the upper holder () to expose the sensor ().

Blood testing device

A blood testing device that can perform blood testing having lighting intensity independent of the number of times of piercing. The blood testing device () has a cover unit () removably installed on negative pressure chambers (). The cover unit () has a circular tube section () surrounding the optical axis of a laser unit () and having a predetermined length in the direction of the optical axis, a cover glass () placed on the optical axis of the laser unit () so as to be located at that end of the circular tube section () which is on the laser unit () side, and a slit () for interconnecting the inside of the circular tube section () and the negative pressure chamber () outside the circular tube section ().
