  • Patent number: 8491498
    Abstract: A sample collection implement S1 includes a container 1 having an accommodation portion 10 in which a liquid 5 for suspending or diluting a sample is accommodated, a sample collection stick 2 being able to be disposed in the accommodation portion 10, a filter 3 provided inside the container 1, and a movable member 4 that can be moved in a predetermined direction inside the container 1 and has a function of pushing the liquid 5 and causing the liquid to pass through the filter 3, when moved in the predetermined direction. With such a configuration, when the liquid 5 is filtered, it is not necessary to move the filter 3 by directly pushing it and a filter with a low mechanical strength can be used as the filter 3. In addition, it is not necessary to use a centrifugal apparatus.

  • Patent number: 6325975
    Abstract: A suction generating device for a sample analysis device is provided. The device comprises four parts, namely, a cover plate 61, a middle plate 62, a bottom plate 63 and an operation plate 64. A protruding portion 642 for compressing the suction generating chamber is formed in an approximately center portion on the lower side of the operation plate 64, a protruding portion 641 for operation is formed in an approximately center portion on the upper side of the operation plate 64. A cavity 631 for inserting the sample analysis device therein is formed in an approximately center portion in the bottom plate 63, and a hole 632 for light irradiation is punched in a determined portion in the cavity 631. A concave portion 623 for fitting the operation plate 64 therein is formed in the middle plate 62, and a window section 621 is formed in the center of the concave portion 623 to let the lower protruding portion 642 on the operation plate 64 protrude therethrough.
