Detailed Description
Referring to fig. 1 to 3, the embodiment of the test tube for loading biological samples according to the present invention is suitable for pre-loading a solvent 91, loading a biological sample 92 during sampling, and then grinding and pulverizing the biological sample 92 by using a grinding rod 93 to extract nucleic acid, wherein the biological sample 92 is illustrated as a bulk biological soft tissue, but the biological sample 92 can be other shapes or biological hard tissue, but not limited thereto. When in use, the grinding rod 93 can be held by hand to grind manually or automatically by a machine, and the use mode is not a limitation of the invention. The test tube for containing a biological sample comprises a tube body 1 and an upper cover 2.
The tube body 1 is formed by integrally molding a transparent plastic material, and the tube body 1 has a top end 101 and a bottom end 102 which are oppositely arranged on an axis L. The tube body 1 includes a tube wall 11 and an extension wall 12. The pipe wall 11 has an inner surface 111 surrounding the axis L, an outer surface 112 opposite to the inner surface 111, and a bottom surface 110 connected to the inner surface 111 and the outer surface 112. The inner tube surface 111 defines a tube channel 100. The tube channel 100 extends in the direction of the axis L, the tube channel 100 having a nozzle 103 at the top end 101 and communicating with the environment, and a bottom opening 104 at the bottom end 102 opposite the nozzle 103. In some variations, the bottom end 102 of the tube passageway 100 may be closed without the bottom opening 104. The outer tube surface 112 is formed with a threaded portion 113 located at the top end 101, and at least one mark 114 located between the top end 101 and the bottom end 102, as shown in fig. 2, the number of the marks 114 is four and arranged at equal intervals, each mark 114 can be used as a volume guide by forming a circle of semi-transparent fog surface by fine biting, and in some variations, each mark 114 can also be a raised line, a groove or a raised point, as long as the mark can be clearly recognized by an operator. Because the pipe body 1 is made of transparent plastic materials, operators can see the contents conveniently. In some variations, the threaded portion 113 and the mark 114 can also be formed on the inner pipe surface 111, and even be omitted. The bottom surface 110 is located at the bottom end 102, and the tube body 1 can be stably placed on a surface (not shown) such as, but not limited to, a table top, through the arrangement of the bottom surface 110, so as to be convenient for use.
The extended wall 12 is located within the tube lane 100, the extended wall 12 separating the tube lane 100 into a sample chamber 105 and a bottom chamber 106, the sample chamber 105 communicating with the nozzle 103, the bottom chamber 106 communicating with the bottom opening 104. In some embodiments, the extension wall 12 extends obliquely from the inner tube surface 111 towards the axis L and surrounds a grinding chamber 120 which is closed at the bottom side, the top side of the grinding chamber 120 communicating with the sample chamber 105 of the tube channel 100. In some variations, the bottom chamber 106 can be omitted, that is, the bottom surface 110 is connected to the extension wall 12, and the extension wall 12 is exposed, so that the tube body 1 can be positioned without falling down by simply placing it on a test tube rack (not shown).
Referring to fig. 2 to 4, the extending wall 12 completely surrounds the axis L and is provided for the axis L to pass through, and the extending wall 12 has an inner wall surface 121 surrounding the grinding chamber 120 and an outer wall surface 122 opposite to the inner wall surface 121. The inner wall surface 121 has a connecting surface portion 123 extending obliquely from the inner tube surface 111 toward the axis L, and a polishing surface portion 124 extending obliquely from the connecting surface portion 123 toward the bottom opening 104. In some variations, the inner wall surface 121 may omit the connecting surface portion 123. In an embodiment, an included angle α 1 between the connecting surface portion 123 and the axis L is greater than an included angle α 2 between the polishing surface portion 124 and the axis L, but in other variations, the included angle α 1 between the connecting surface portion 123 and the axis L may also be smaller than the included angle α 2 between the polishing surface portion 124 and the axis L, as long as the included angle α 1 is different from the included angle α 2 to form a turning surface. In one embodiment, the grinding chamber 120 is disposed symmetrically around the axis L and has a conical shape, and the grinding chamber 120 has a low point 125 located on the grinding surface 124, and the low point 125 is for the axis L to pass through. In some variations, the polishing surface portion 124 may be formed only on the ring side of the inner wall surface 121. In other variations, the grinding chamber 120 may have a cylindrical shape, and the grinding surface 124 may be formed on the bottom side or the ring side of the inner wall surface 121. In this embodiment, the connecting surface 123 can guide the grinding rod 93 to slide into the grinding chamber 120, and obtain a better force application angle. The connecting surface 123 is, for example, but not limited to, a smooth surface, which enables the biological sample 92 overflowing from the polishing chamber 120 to easily slide back into the polishing chamber 120 during the processing process, so that the biological sample 92 can be collected in the polishing chamber 120, and the polishing effect is better.
The grinding surface 124 has a rough structure 126, the biological sample 92 can be directly ground in the grinding chamber 120 through the rough structure 126 (see fig. 2), the rough structure 126 of this embodiment is a transcription from a mold surface, and the common mold surface processing methods include polishing, electrical discharge texturing, chemical liquid texturing and laser texturing, which is explained in this embodiment as electrical discharge texturing, so that the grinding surface 124 has a semitransparent matte effect. In other variations, the roughness structure 126 may be formed by sand blasting, laser engraving, electrical discharge machining, or chemical etching, so long as a regular or irregular and fine concave-convex surface is generated to have a polishing effect. It should be noted that, in order to prevent the biological sample 92 from being completely taken out due to the coarse structure 126 after being ground, the coarse structure 126 should have a fine concave-convex surface so as not to catch the refined biological sample 92 after being ground, but the invention is not limited to the geometric shape and/or distribution area of the coarse structure 126. In practical use, if the grinding rod 93 can be matched with the grinding chamber 120 in a shape and size matching manner, or a texture structure is formed at the front end of the grinding rod 93, the grinding effect can be further improved, and the advantage of saving labor is achieved.
Referring to fig. 3, 5 and 6, the upper cap 2 is detachably disposed on (in this embodiment, screwed to) the tube body 1 and is used to close the nozzle 103. The upper cover 2 is formed by integrally molding a plastic material and has an inner annular wall 21 and an outer annular wall 22 surrounding the axis L and arranged at intervals, an annular groove 23 surrounding the inner annular wall 21 and the outer annular wall 22 is formed by matching the inner annular wall 21 and the outer annular wall 22, and the annular groove 23 is used for the pipe wall 11 to penetrate and joint. In one embodiment, the inner surface of the outer annular wall 22 has a spiral part 221 facing the annular groove 23, and the spiral part 221 is screwed to the screw part 113 of the pipe body 1. In one embodiment, the outer surface of the outer annular wall 22 has an anti-slip structure formed by a combination of a plurality of ribs 222 parallel to the axis L. When the upper cover 2 is screwed to the tube body 1, the protrusion 222 can prevent the hand from slipping during the tightening process. By the engagement of the pipe wall 11 penetrating the annular groove 23 and the spiral part 221 engaging the threaded part 113, the solvent 91 in the pipe body 1 can be prevented from leaking out and the leakage can be prevented. In some variations, the elastic deformation property of the plastic can be adopted, and the width of the annular groove 23 is slightly smaller than the thickness of the tube wall 11, so that the tube body 1 and the upper cover 2 are engaged in a tight fit manner, and the upper cover 2 can be detachably arranged on the tube body 1 and has a function of convenient storage, therefore, the engagement manner or/and the position of the tube body 1 and the upper cover 2 are not limited by the invention.
Referring to fig. 5 and 7, the spiral portion 221 of the upper cover 2 has a double-threaded structure, the inner annular wall 21 has at least one protrusion 211 facing the spiral portion 221, and the at least one protrusion 211 is matched with the spiral portion 221 and respectively pressed against the tube wall 11 of the tube body 1 from both sides to increase the watertight effect, so as to prevent the solvent 91 (see fig. 6) from leaking during the storage or transportation process. The at least one protrusion 211 may be a bump, a protruding strip or a protruding block.
Therefore, when the sample is sampled and detected, the upper cover 2 of the invention is firstly opened, the sampled and detected biological sample 92 is put into the sample chamber 105 of the tube body 1, the biological sample 92 is immersed into the solvent 91 and protected, and then the upper cover 2 is screwed on the tube body 1 to achieve the watertight effect, so as to ensure that the solvent 91 and the biological sample 92 cannot leak. Then, the present invention is carried or transported to a testing room (not shown), the upper lid 2 is opened, and the grinding rod 93 is extended into the grinding chamber 120 for tissue grinding and refining. In the process of sampling, storing, transporting and grinding and refining the tissues in the examination room, the biological samples are always in the tube body 1 without changing the tube, so the invention can simplify the treatment process of the biological samples 92 and save the treatment time. In addition, the pipe body 1 is made of plastic materials, so that the pipe has the advantages of light weight and no breakage, is convenient to take and can improve the use safety.
In summary, in the test tube for loading a biological sample according to the present invention, the uneven surface of the roughness structure 126 of the polishing surface 124 can generate a friction force to fix the position of the biological sample 92, so that the biological sample is not easily slipped off, and a shearing force and a stirring force are generated to the biological sample 92 by the uneven surface of the roughness structure 126, so that the biological sample 92 can be refined and homogenized. Therefore, after the biological sample 92 is put into the tube body 1, the upper cover 2 can be tightly covered to obtain good preservation and convenient carrying or transportation. When the examination and analysis are to be performed, the biological sample 92 can be directly processed in the grinding chamber 120 by only opening the upper cover 2 without tube replacement, so that the processing flow of the biological sample 92 can be simplified, and the biological sample 92 can be prevented from being contaminated. In addition, the pipe body 1 is made of plastic materials, so that the pipe has the advantages of light weight and no breakage, is convenient to take and can improve the use safety. In this embodiment, the extending wall 12 of the tube body 1 is inclined to enhance the concentration effect of the biological sample 92 in the grinding chamber 120, so as to achieve a better grinding effect, thereby achieving the objective of the present invention.
The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
