Abstract: There is provided an automatic analysis device that can easily realize introduction and replacement of additional reagents in operation even in a small-scale configuration. The automatic analysis device includes a reagent dispensing mechanism 107 that dispenses a reagent from a reagent container 113 containing a reagent, and a normal reagent storage portion 130 that stores a reagent container and an additional reagent storage portion 111. The normal reagent storage portion 130 is positioned in a normal movable area 132, which is a portion of a movable area 131 of the reagent dispensing mechanism 107 and the additional reagent storage portion 111 is positioned in an area excluding the normal movable area 132 in the movable area 131 of the reagent dispensing mechanism 107. The reagent dispensing mechanism 107 performs an access operation in the normal movable area 132 in the normal operation and performs an access operation to the additional reagent storage portion 111 upon receiving a predetermined instruction.

Abstract: In order to aspire to higher sensitivity in an automatic analysis device, it is important to prevent the mixing of dust and the like in a reaction part in which a sample and a reagent react. The present invention presents an automatic analysis device that is provided with a configuration for making the pressure inside a specific block in the device such as a reaction part, or inside the device become positive. By making the pressure become positive and forming an air flow that flows out from the inside of the reaction part or the device, it is possible to limit, to a certain amount or less, the amount of dust penetrating into the reaction part.

Abstract: A blood collecting device collects blood in a short time after puncture without scattering the blood into the open air other than a container for collecting the blood. One of representative blood collecting devices has a container unit that includes a screw portion, a holder that holds the container unit serving as a system whose one end is closed, a puncture unit that can be attached to the container or the holder, a through-hole of the puncture unit, and a puncture unit protection member that protects the puncture unit and the container unit.

Abstract: Stepped portions of a flow channel are reduced by completely fixing the channel that extends to the measuring unit, and reducing connections in the channel, thereby to suppress a disturbance in the flow of the liquid suctioned into the measuring unit. A means is provided so that the reaction solution and reagent suctioned will move towards the channel through which the liquids are suctioned.
