Abstract

A mechanism for collecting a trace of a biological sample to be used for a biological sample analysis, and for preparing a diluted solution of the sample. A container for specimen preparation includes: a biological sample collecting device; and a container for sample dilution. The biological sample collecting device includes: a capillary tube having openings formed at both ends thereof; and a support member for supporting the capillary tube. The container for sample dilution includes: an opening; and a swirl flow generating member formed on an inner wall of the container for sample dilution. The capillary tube of the biological sample collecting device is arranged inside the container for sample dilution by the support member.

First claim

1 . A container for specimen preparation, comprising:
a biological sample collecting device; and a container for sample dilution, the biological sample collecting device comprising:
a capillary tube having openings formed at both ends thereof; and
a support member for supporting the capillary tube,
the container for sample dilution comprising:
an opening; and
a swirl flow generating member formed on an inner wall of the container for sample dilution, and
the capillary tube of the biological sample collecting device being arranged inside the container for sample dilution by the support member.

2 . The container for specimen preparation according to claim 1 , wherein the biological sample collecting device further comprises a fixing member for fixing the biological sample collecting device to the container for sample dilution, so that the capillary tube of the biological sample collecting device is arranged in the container for sample dilution.

3 . The container for specimen preparation according to claim 1 , further comprising a lid for closing the opening of the container for sample dilution.

4 . The container for specimen preparation according to claim 3 , wherein the fixing member comprises the lid.

5 . The container for specimen preparation according to claim 3 , wherein the lid has a hole formed therein to allow passage of an injection tube for injecting a liquid into the container for sample dilution, or the lid comprises a film capable of being pierced through by the injection tube.

6 . The container for specimen preparation according to claim 1 , wherein the capillary tube is arranged in the container for sample dilution so that a position of an upper end of the capillary tube of the biological sample collecting device is level with or lower than a position of an upper end of the swirl flow generating member formed on the inner wall of the container for sample dilution.

7 . The container for specimen preparation according to claim 1 , further comprising a guide for arranging the capillary tube of the biological sample collecting device at a desired position in the container for sample dilution.

8 . The container for specimen preparation according to claim 1 , further comprising an engaging member for retaining the container for specimen preparation on a rack.

9 . A biological sample collecting device, comprising:
a capillary tube having openings formed at both ends thereof; and a support member for supporting the capillary tube.

10 . A container for sample dilution, comprising:
an opening; and a swirl flow generating member formed on an inner wall of the container for sample dilution.

11 . The container for specimen preparation according to claim 1 , wherein the swirl flow generating member comprises at least one of:
a slope formed to extend from a side surface of the inner wall of the container for sample dilution toward a bottom of the inner wall of the container for sample dilution; a conical protrusion formed on the side surface of the inner wall of the container for sample dilution or on a center of the bottom of the inner wall of the container for sample dilution; a plurality of blade-form protrusions formed on the bottom of the inner wall of the container for sample dilution; a spiral protrusion formed to extend from the side surface of the inner wall of the container for sample dilution toward the bottom of the inner wall of the container for sample dilution; and a recess formed at an off-center position to the bottom of the container for sample dilution.

12 . The container for sample dilution according to claim 10 , wherein the swirl flow generating member comprises at least one of:
a slope formed to extend from a side surface of the inner wall of the container for sample dilution toward a bottom of the inner wall of the container for sample dilution; a conical protrusion formed on the side surface of the inner wall of the container for sample dilution or on a center of the bottom of the inner wall of the container for sample dilution; a plurality of blade-form protrusions formed on the bottom of the inner wall of the container for sample dilution; a spiral protrusion formed to extend from the side surface of the inner wall of the container for sample dilution toward the bottom of the inner wall of the container for sample dilution; and a recess formed at an off-center position to the bottom of the container for sample dilution.
