Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Please refer to fig. 1 and fig. 2, which are a sectional view of the sputum sampling tube 1 and a sectional view of the sputum sampling tube with its parts separated. The sputum sampling tube 1 comprises a sampling tube 2, a sampling tube cover 21, a liquid storage tube 3, a liquid storage tube cover 31 and a puncture needle 4.

The sampling pipe 2 and the liquid storage pipe 3 are square pipes with the lower ends closed and the upper ends opened, the lengths of the sampling pipe and the liquid storage pipe are the same, and the side walls and the bottom ends are flat walls. Sampling pipe 2 and liquid storage pipe 3 set up side by side, and the opening and the bottom at the two top all are the parallel and level each other. The sampling pipe 2 and the liquid storage pipe 3 are arranged between the side walls which are close to each other, and a channel 5 is arranged at the position close to the bottom end.

A partition plate 32 parallel to the bottom end of the liquid storage tube 3 is provided in the liquid storage tube 3 at a position above the passage 5, and partitions the interior of the liquid storage tube 3 into an upper part and a lower part, which are respectively designated as a first chamber 33 and a second chamber 34. The middle of the clapboard 32 is provided with a round liquid taking hole 35. The first chamber 33 communicates with the opening of the reservoir 3 and the second chamber 34 communicates with the channel 5.

Sampling tube 2 is used for holding the sputum sample, and first chamber 33 is used for storing sodium hydroxide solution. Before detection, the sodium hydroxide solution in the first chamber 33 is discharged into the second chamber 34 and the channel 5 through the liquid taking hole 35, and is mixed with the sputum sample in the sampling tube 2.

The sampling tube 2 is wider than the reservoir tube 3 to form a larger opening at its top end to facilitate the insertion of the sputum sample during sampling. The bottom end of the sampling pipe 2, the bottom end of the channel 5 and the bottom end of the liquid storage pipe 3 jointly form a flat wall which is mutually communicated. The sputum sample and the sodium hydroxide solution can smoothly flow between the flat walls without obstruction, so that mixing can be smoothly realized.

The opening joint on 2 tops of sampling pipe is fixed with sampling pipe lid 21, seals the space in sampling pipe 2, prevents that the sputum sample from leaking. A liquid storage tube cover 31 is fixed at the opening at the top end of the liquid storage tube 3 in an adhesive mode, so that the space in the liquid storage tube 3 is sealed, and the leakage of the sodium hydroxide solution is prevented. A circular mounting hole 36 is provided in the center of the reservoir cover 31. The mounting hole 36 is coaxial with the liquid taking hole 35, the inner wall of the mounting hole 36 is provided with threads, and the inner wall of the liquid taking hole 35 is a smooth wall.

The mounting hole 36 is used for mounting the puncture needle 4, and the puncture needle 4 is further inserted into the liquid taking hole 35 to seal the liquid taking hole 35. The opening and closing of the liquid taking hole 35 are realized by lifting the puncture needle 4.

The lancet 4 comprises a handle 41, a mounting section 42, an attachment section 43, and a sealing section 44 connected in series. The handle 41 is a circular handle with a larger diameter but not exceeding the width of the liquid storage tube 3, and has a plurality of grooves on the edge to increase friction force for convenient hand-held rotation.

The mounting section 42 is a cylinder having a diameter equal to that of the mounting hole 36 and is coaxially fixed to the bottom surface of the handle 41. The outer wall of the mounting section 42 is threaded to engage the mounting hole 36. The connecting section 43 is a cylinder with a diameter smaller than that of the mounting section 42 and larger than that of the liquid taking hole 35, and is longer. Coaxially secured to the bottom end of the mounting section 42. The sealing section 44 is a circular truncated cone having one end with a diameter equal to that of the connecting section 43 and the other end with a diameter smaller than that of the connecting section 43. One end having a diameter equal to that of the connecting section 43 is coaxially fixed to the bottom end of the connecting section 43.

The sealing section 44 of the lancet 4 is inserted into and partially through the access hole 35 into the second chamber 34 by inserting one end of the sealing section 44 through the mounting hole 36 until the mounting section 42 threadably engages the mounting hole 36 and is rotated downward. At this time, the sealing section 44 abuts against the inner wall of the liquid taking hole 35, so that the liquid taking hole 35 is sealed. The sealing section 44 rises during reverse rotation to expose the access port 35, allowing the sodium hydroxide solution to drain down to the second chamber 34.

During production, a sealing gasket is preset in the liquid taking hole 35, and the first chamber 33 is filled with sodium hydroxide solution. The cartridge cap 31 is then placed over the spike 4 and the gasket is pushed out down into the second chamber 34. The gasket may be removed in subsequent processing.

During sampling, the sampling tube cover 21 is uncovered, the sputum sample is collected in the sampling tube 2, and the sampling tube cover 21 is closed.

Before detection, an operator roughly estimates the required volume of the sodium hydroxide solution according to the volume of the sputum sample. Handle 41 is then held, lancet 4 is rotated to raise sealing section 44, exposing access hole 35, and sodium hydroxide solution drains down into second chamber 34.

After the appropriate volume of sodium hydroxide solution is obtained, the needle 4 is rotated to lower the sealing section 44 and close the access hole 35.

The above-mentioned only be the embodiment of the present invention, not consequently the restriction of the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transform made of the content of the specification of the present invention, or directly or indirectly use in other relevant technical fields, all including in the same way the patent protection scope of the present invention.
