[0002] The existing quantitative tube generally includes an integrally formed tube body, which is provided with a leakage chamber and a quantitative chamber located in the leakage chamber. When in use, liquid flows into the quantitative chamber. When the quantitative chamber is filled with liquid, the excess liquid overflows into the leakage chamber, thereby keeping the liquid volume in the quantitative chamber constant. However, during use, the liquid needs to be sucked out of the quantitative chamber by means of a liquid transfer device to achieve quantitative liquid discharge, and then the quantitative liquid is transferred to a sampling container, etc. However, since the cost of the liquid transfer device is not low and a large number of consumables such as pipette tips are consumed, the cost of quantitative liquid discharge is high and cannot meet industry requirements.

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] like Figure 1-3As shown, a puncturable quantitative tube includes a main body 20 and a bottom plug 10; a leakage chamber 21 is arranged in the main body 20, and the main body 20 is provided with a built-in wall 30 extending into the leakage chamber 21, and an upper quantitative chamber 32 is formed in the built-in wall 30, and the bottom plug 10 is arranged on the main body 20, and the bottom plug 10 is provided with a lower quantitative chamber 11, and the lower quantitative chamber 11 is connected to the upper quantitative chamber 32; at least a part of the cavity wall of the lower quantitative chamber 11 is formed as a matching wall 12 suitable for being pierced by a puncture needle.

[0024] During use, liquid flows into the upper quantitative chamber 32 and the lower quantitative chamber 11. When the liquid fills the upper quantitative chamber 32 and the lower quantitative chamber 11, the excess liquid will overflow into the leakage chamber 21, thereby keeping the liquid amount in the upper quantitative chamber 32 and the lower quantitative chamber 11 constant. If liquid needs to be discharged, the puncture needle can be used to pierce the matching wall 12, so that the liquid in the upper quantitative chamber 32 and the lower quantitative chamber 11 can flow outward, thereby achieving quantitative liquid discharge without using a pipetting device, which is convenient for quantitative liquid discharge. Therefore, the puncturable quantitative tube of the present invention adopts a combination of a main body 20 and a bottom plug 10, and at the same time, the main body 20 is provided with a built-in wall 30 extending into the overflow chamber, an upper quantitative chamber 32 is formed in the built-in wall 30, and a lower quantitative chamber 11 is provided on the bottom plug 10, and at the same time, at least a part of the cavity wall of the lower quantitative chamber 11 is formed into a matching wall 12 suitable for puncture by a puncture needle, so that quantitative liquid discharge can be achieved with the help of a puncture needle. Compared with the existing quantitative tube that can only achieve quantitative liquid discharge with the help of a pipetting device, the puncturable quantitative tube of the present invention is convenient for quantitative liquid discharge and can reduce the cost of quantitative liquid discharge.

[0025] The bottom plug 10 includes a bottom surrounding wall 13 and a partition wall; the partition wall is arranged in the bottom surrounding wall 13, and the bottom surrounding wall 13 and the partition wall surround the lower quantitative bin 11; the partition wall is formed as the matching wall 12. By adopting the above arrangement, the formation of the lower quantitative bin 11 can be facilitated and the cost can be reduced.

[0026] The bottom plug 10 is also provided with a bottom cavity 15, and the bottom quantitative bin 11 is separated from the bottom cavity 15 by a partition wall. The bottom quantitative bin 11 is located above the partition wall, and the bottom cavity 15 is located below the partition wall. By adopting the above arrangement, the material used for the bottom plug 10 can be reduced, thereby reducing the cost.

[0027] The lower end of the bottom surrounding wall 13 is also provided with an outwardly protruding body 16, and the outwardly protruding body 16 is supported below the main pipe body 20. By adopting the above arrangement, the stability of the cooperation between the bottom plug 10 and the main pipe body 20 can be improved.

[0028] At least a portion of the bottom surrounding wall 13 is embedded in the main tube 20. By adopting the above arrangement, the stability of the cooperation between the bottom plug 10 and the main tube 20 can be further improved.

[0029] The top surface of the built-in wall 30 is lower than the top surface of the main body 20. When in use, after the liquid fills the upper quantitative chamber 32 and the lower quantitative chamber 11, the excess liquid can flow over the top surface of the built-in wall 30 into the leakage chamber 21.

[0030] The inner wall 30 includes a transverse wall body 31 and an inner tube wall 35; the transverse wall body 31 is arranged on the main tube body 20, and the inner tube wall 35 is arranged on the transverse wall body 31 and extends upward; the upper quantitative bin 32 extends from the inside of the inner tube wall 35 to the transverse wall body 31. The top surface of the inner tube wall 35 is lower than the top surface of the main tube body 20. By adopting the above arrangement, the manufacture and formation of the upper quantitative bin 32 can be facilitated, and the manufacturing cost of the inner wall 30 can be reduced.

[0031] Preferably, the upper quantitative chamber 32 includes a main chamber section 33 and a guide section 34; the guide section 34 is located below the main chamber section 33 and communicates with the main chamber section 33. From the upper end of the guide section 34 to the lower end of the guide section 34, the diameter of the guide section 34 gradually decreases, and by adopting the above structure, the liquid in the upper quantitative chamber 32 can be conveniently guided to the lower quantitative chamber 11 through the guide section 34.

[0032] Specifically, the main compartment section 33 is formed in the built-in tube wall 35, and the guide section 34 is formed on the transverse wall 31. By adopting the above arrangement, processing can be facilitated.

[0033] The present invention also discloses a quantitative tube puncture assembly, comprising a puncture needle and the above-mentioned puncturable quantitative tube. When liquid needs to be discharged, the puncture needle can be used to puncture the matching wall 12, so that the liquid in the upper quantitative chamber 32 and the lower quantitative chamber 11 can flow out through the perforation formed by the puncture of the matching wall 12, thereby achieving liquid discharge.

[0034] When the puncture needle pierces the matching wall 12, the liquid in the upper quantitative chamber 32 and the lower quantitative chamber 11 can be discharged outward through the hole formed by the puncture needle piercing the matching wall 12. However, as a preferred embodiment of the present invention, the puncture needle can be provided with a through channel, and when the puncture needle pierces the matching wall 12, the liquid in the upper quantitative chamber 32 and the lower quantitative chamber 11 can flow outward through the through channel of the puncture needle, so as to facilitate the operation, and the through channel can guide the flow of the liquid.

[0035] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
