  • Bodily fluid sampler
    Patent number: 10126211
    Abstract: A bodily fluid sampler includes a suction part that sucks the bodily fluid, a main body part that includes a ventilation channel which allows gas for discharging the bodily fluid sucked by the suction part to pass therethrough, and a blocking part that is provided between the main body part and the suction part, and the blocking part preventing the bodily fluid sucked by the suction part from flowing into the main body part. An inner diameter of the opening part formed in the blocking part is smaller than an inner diameter of the suction part at a surface where the suction part and the blocking part make contact with each other, and thus, the bodily fluid is prevented from being sucked by the suction part more than a predetermined amount.
