SAMPLE COLLECTION AND DIVISION DEVICE FOR EXAMINING BIOLOGICAL SAMPLE

摘要

The present invention relates to a sample division device and, more specifically, to a sample division device comprising: a chamber perforated in a predetermined longitudinal direction, and having a first hollow part having an opening portion at one end thereof; a housing having one end thereof connected to the chamber, and having a second hollow part of which both ends are open and communicating with the first hollow part in the chamber; and a buffer tube having a filling space such that a predetermined solution is filled therein, and having an opening at one end thereof, and of which the side at which the opening is formed is connected and fixed to the other end of the housing, wherein the chamber includes: a sample part provided at the other end of the first hollow part, and capable of collecting a predetermined sample or discharging fluid inside the first hollow part; and an extending protrusion part provided in the first hollow part and extended in the longitudinal direction of the first hollow part, the buffer tube has a sealing membrane for sealing the opening such that the predetermined solution is filled in the filling space, the housing is connected to the chamber such that the position thereof is changed with respect to the chamber, and when the housing is displaced to approach the chamber, the sealing membrane is pierced by the extending protrusion part such that the solution is discharged to the outside through the sample part.
