Analysis device

An analyzer for analyzing a component in a sample using an analysis kit comprising a liquid reservoir containing a liquid and having an opening at an upper surface of the analysis kit, a sealing film disposed at the upper surface of the analysis kit and sealing the opening of the liquid reservoir, and a measurement passage connecting to the liquid reservoir, the analyzer comprising:

• a placement section configured to support the analysis kit;
• an opposing wall disposed above the analysis kit, a recess being formed at the lower face of the opposing wall and being disposed above the opening of the liquid reservoir;
• a pump configured to send air;
• a gas introduction tube connected to the pump to introduce air from the pump into the recess, the opposing wall being provided with the gas introduction tube so that an outlet port of the gas introduction tube is positioned at a position in the recess;
• a piercing pin comprising:
• a column extending downwards from an inner face of the recess in which the outlet port of the gas introduction tube is positioned to outside of the recess;
• and
• a projection extending from the leading end of the column in a direction intersecting the downward direction;
• and
• a measurer configured to measure a characteristic of the component present in the sample at the measurement passage,
• wherein the opposing wall descends and the lower face of the opposing wall makes close contact with the upper surface of the analysis kit whereby the piercing pin is inserted into the liquid reservoir and pierces the sealing film and a gap between the piercing pin and the sealing film is formed, and
• the pump sends air from the recess into the liquid reservoir through the gap to send the liquid in the liquid reservoir to the measurement passage.
