Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1, the present embodiment includes a tube body 1, a sealing cap 2, a cap sealing ring 3, a suction head 4, a push rod 5, and a rod sealing ring 6, wherein the suction head 4, the push rod 5, and the rod sealing ring 6 constitute a suction mechanism.

The upper end of the pipe body 1 is a pipe opening, and the upper end of the pipe body 1 is screwed to the sealing cap 2, whereby the sealing cap 2 is screwed to the pipe opening of the pipe body 1. The middle of the sealing cover 2 is formed into a notch 201 which is downwards clamped into the pipe orifice, and the middle of the notch 201 is provided with a through hole for the suction head 4 to penetrate through. A cover sealing ring 3 surrounding the through hole is embedded and fixed in the notch 201 and is used for supporting and sealing the suction head 4. The suction head 4 vertically penetrates through a through hole of the notch 201 and extends into the pipe body 1, sealing is formed between the suction head 4 and the notch 201 through the cover sealing ring 3, and the lower end, located in the pipe body 1, of the suction head 4 is a suction opening. Except that the upper end of the push rod 5 protrudes out of the top of the suction head 4, the rest part of the push rod 5 is slidably arranged in the suction head 4, a fixed rod sealing ring 6 is sleeved on the lower end ring of the push rod 5 positioned in the suction head 4, and the lower end of the push rod 5 is sealed with the inner wall of the suction head 4 through the rod sealing ring 6.

As shown in fig. 2, in the present embodiment, the tube body 1 is a hollow rotator with an opening at one end, the upper end is flat, and the tube opening is provided with a thread.

In the embodiment, as shown in fig. 3, the sealing cap 2 is a revolving body, the inner side of the sealing cap is provided with threads to match with the threads at the upper end of the tube body 1, the inner side of the top of the sealing cap is provided with a notch 201 to match with the tube opening of the tube body 1 to form a seal, and the sealing ring 3 is fixed in the notch 201 to support and seal the suction head 4.

As shown in FIG. 4, in this embodiment, the suction nozzle 4 is a rotary structure, the suction nozzle 4 is gradually tapered toward the lower portion, two annular rims 401 are provided at the upper end of the suction nozzle 4 for positioning and holding, the upper end of the suction nozzle 4 is open, and a suction port 402 at the lower end of the suction nozzle 4 is a fine hole having a diameter significantly reduced from the inside of the suction nozzle 4.

The push rod 5 is placed in the cavity of the suction head 5, and the rod sealing ring 6 at the lower end part prevents liquid from leaking or contacting with the outside.

As shown in fig. 5, when the sample liquid is loaded, the flap 2 is unscrewed to load the sample liquid or other articles, which are common in the prior art, such as a throat swab at a site where the sample liquid and the nucleic acid are sampled. Because the opening of the tube body 1 is sealed by the sealing cover 2 through thread fit, the gap between the sealing cover 2 and the outer side of the suction head 4 is sealed by the cover sealing ring 3, the gap between the inner side of the suction head 4 and the push rod 5 is sealed by the rod sealing ring 6, and the preservation tube forms an integrally sealed carrier and can be used for transferring samples.

As shown in fig. 6, when the sample liquid is sucked, the push rod 5 is lifted up relative to the fixed tube 1, the sealing cap 2 and the suction head 4, the rod sealing ring 6 is driven to move, a certain negative pressure is formed in the suction head 4, and the sample liquid in the storage tube is sucked into the suction head 4. By controlling the movement of the push rod 5, a desired amount of sample liquid can be sucked.

As shown in FIG. 7, the tube body 1 and the cap 2 are fixed, the tip 4 is pulled out, and the sample liquid sucked into the tip 4 is held in the tip 4 and removed from the tube body. Because the suction head has negative pressure inside, the sample liquid can not drip. The pipetting operation is carried out without opening the closure 2.

As shown in FIG. 8, by moving the pipette tip 4 to a predetermined position and moving the push rod 5 downward, the sample liquid can be discharged to the carrier.

After the required sample liquid is obtained, the suction head 4, the push rod 5 and the rod sealing ring 6 are inserted back to the original position, so that the whole storage tube can be realized, and the effect of sealing and storing the residual sample liquid can be achieved.

The embodiments of the present invention are only descriptions of the preferred embodiments of the present invention, not right the present invention is designed and limited, without departing from the design concept of the present invention, the technical personnel in the field should fall into the protection scope of the present invention for various modifications and improvements made by the technical solution of the present invention, and the technical contents of the present invention are all recorded in the claims.
