DISPOSABLE SAMPLE COLLECTION TUBE AND APPLICATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/227669
Kind Code:
A1
Abstract:
A disposable sample collection tube, comprising a tube body (2) internally provided with a cavity, and a tube spoon (1) provided with a tube cover (3) on the top portion and being rotatably connected to the top portion of the tube body (2) by means of the tube cover (3); a partition (22) having an overflow hole (21) is provided at the lower portion of the tube body (2), and the partition (22) divides the inside of the tube body (2) into an upper cavity and a lower cavity; the tube spoon (1) is provided inside the upper cavity, and a lower rubber plug (4) fitting the tube spoon is provided inside the lower cavity; the lower rubber plug (4) is provided with a sample collection cavity (41) which is in communication with the upper cavity through the overflow hole (21). The present invention removes the rationing scraper from the original structure and avoids the process of using a rationing scraper to scrape extra feces during use, facilitating use, and being simple and intelligible; arranging an elastic snap-fit locker (81) avoids the risk of breakage and the risk of the lower rubber plug (4) being ejected after mounting due to the fixing not being firm, facilitating mounting, being less vulnerable to damage, and making the fixing firm. An annular baffle (6) can block large particles, thereby avoiding the risk of blocking. Said device is ingeniously designed, has a simple structure, and is easy to implement.
