Abstract: An expansion/compression mechanism of a piston rod assembly is composed of a bush shaft, a first cylindrical piston rod that is screwed with the bush shaft, a second cylindrical piston rod that is screwed with the first piston rod, and a piston rod holding member for housing the bush shaft and these piston rods. Therefore, the piston rods move linearly in multiple stages.

Abstract: In the present invention, a metal upper cover that covers an upper face opening of a frame is mounted on this upper face opening, and a bent piece that is inserted into a bent piece insertion hole provided to the frame is provided to a portion of the upper face cover on the side of a sensor insertion hole. Furthermore, ground connection pieces formed by extending the outside of the left and right sides of the frame from the upper face toward the lower face are provided in portions opposite the left and right edges linked to the edge of the top cover on which the sensor insertion opening of the frame is provided.

Abstract: An engagement component that engages with the rear part of a sensor mounted to a sensor connector, and a manipulation body that moves this engagement component to a sensor insertion opening side are provided. In addition, there are provided a manipulation rod that is engaged at one end with the manipulation body and whose other end is pulled out of a main body case through a through-hole provided to the main body case, and a manipulation component that is linked to the other end side of this manipulation rod. The device further comprises an annular wall that is provided outside the main body case and around a through-hole, and a metal slide bearing that covers this annular wall, and a resin sliding member that is slid with respect to a metal slide bearing is provided on the metal slide bearing side of the manipulation component.

Abstract: A partition wall is provided between a display section and a sensor mount inside a main case. A control board housing chamber is disposed on the display unit side of the partition wall, and a measurement board housing chamber is disposed on the sensor mount side of the partition wall. A control board is housed in the control board housing chamber, and a measurement board and a temperature sensor are housed in the measurement board housing chamber.

Abstract: A puncture device capable of preventing needle stick accidents and of reducing the burden on patients during operation. In this puncture device, a puncture needle cartridge comprises: a lancet body having a puncture needle at one end with the other end being to be held by a puncture instrument body; a protective cap; and a puncture needle holder engaged with the lancet body to rotate together with the lancet body about a rotation axis P. A mounting member rotates together with the puncture needle holder with a boss guided by a slit through being pressed by the puncture needle cartridge in a direction of mounting in a case, and is mounted in the case. The protective cap, formed integrally with the lancet body, is prevented from rotating by being grasped and is separated from the lancet body with the rotation of the mounting member.

Abstract: Biological sample measurement device includes biological sample measuring instrument, and temperature information supply instrument which supplies temperature information regarding a measurement environment to biological sample measuring instrument and has holding portion of biological sample measuring instrument on the upper surface thereof. Biological sample measuring instrument has main body case, measurement unit provided inside main body case, a control unit connected to the measurement unit, and temperature information reception unit connected to the control unit. Holder has temperature sensor, and temperature information transmission unit which is connected to temperature sensor and transmits the temperature information to temperature information reception unit.

Abstract: With this device for measuring a biological sample, a partition wall (14) is provided between a display section (2) and a sensor mount (5) inside a main case (1). A control board housing chamber (15) is disposed on the display unit (2) side of the partition wall (14), and a measurement board housing chamber (16) is disposed on the sensor mount (5) side of the partition wall (14). A control board (6) is housed in the control board housing chamber (15), and a measurement hoard (7) and a temperature sensor (13) are housed in the measurement board housing chamber (16).

Abstract: Provided are a blood collecting puncture device having high safety which can hygienically maintain the inside of a magazine and prevent infection, and the magazine. A blood collecting puncture device (100) has a blood collecting puncture device body (101) removably incorporating a magazine (107) for housing lancets for puncturing human skin. The blood collecting puncture device body (101) has a first housing section (501) for housing not-yet-used lancets (303) and a second housing section (507) for housing used lancets to be disposed of. When a rotor (402) is rotated, individual lancets are sequentially conveyed on a one-by-one basis to a stock position (502), a puncture position (503), and a disposal position (504), and this causes a not-yet-used lancet to be housed in the first housing section (501) and also causes a used lancet to be housed in the second housing section (507), so that the lancets are separately housed in spaces isolated from each other.
