The pull block is pulled upward by the index finger and middle finger, and the thumb presses down hard on the top of the press block. The pull block drives the movable rod to move upward in the slot. The movable rod that moves upward forms a tight fit with the side wall of the slot through the elastic force of the rubber ring at the bottom, thereby pulling the gas in the outer tube upward during the upward movement. During the contraction of the gas, the blood sample enters the outer tube through the capillary tube, and the blood sample entering the outer tube is soaked until the sample addition area of ​​the test strip is soaked.
