Description

Technical Field

[0001] The present invention relates to the technical field of sample preservation devices, and particularly to a tissue sample preservation container. Background Art

[0002] In modern medical diagnosis, pathological research, and personalized medicine, the quality of tissue sample preservation and transportation directly affects the accuracy of test results. With the rapid development of technologies such as molecular biology, genomics, and liquid biopsy, higher requirements have been put forward for the preservation conditions of tissue samples (such as tumor tissues, biopsy samples, surgically resected specimens, etc.). Traditional tissue preservation methods mainly rely on formalin-fixed paraffin embedding (FFPE) or cryopreservation at low temperatures (-80°C or liquid nitrogen).

[0003] Although FFPE is convenient for long-term storage, it may cause nucleic acid and protein degradation, affecting the sensitivity of molecular detection and resulting in inaccurate test results; while cryopreservation at ultra-low temperatures can better preserve biomolecules, but it has high costs and harsh transportation conditions. Moreover, in clinical work, due to the condition of the disease, doctors need to collect samples from multiple locations of the patient for separate tests, and finally diagnose the condition. Doctors will put the samples into different boxes and then send the boxes for inspection. In this process, the boxes of different patients may be mixed up, resulting in the inability to complete all the tests of the same patient and posing a risk of incomplete disease diagnosis.

[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Invention

[0033] In order to enable those skilled in the art to better understand the solutions of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0036] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or sections, these components, elements, regions, layers, or sections are not limited by these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or section from another. Thus, a first component, element, region, layer, or section as referred to in the examples described herein may also be termed a second component, element, region, layer, or section without departing from the teachings of the examples.

[0037] For ease of description, spatial relationship terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another as shown in the figures. Such spatial relationship terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.

Thus, the term "above" includes both the orientation of "above" and "below" depending on the spatial orientation of the device. The device may be positioned in other ways as well, and the spatial relationship terms used herein will be interpreted accordingly.

[0038] The terms used herein are for the purpose of describing various examples only and are not intended to limit the disclosure. Unless the context clearly dictates otherwise, the singular forms are also intended to include the plural forms. The terms "comprises", "comprising", and "having" list the stated features, quantities, operations, components, elements, and / or combinations thereof that exist, but do not preclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0039] Currently in clinical work, tissue samples taken from patients by biopsy are generally stored in sample boxes. Medical staff will attach labels to the boxes and then send them for inspection. In some cases, to improve the accuracy of diagnosis, it is necessary to collect samples from multiple locations on the patient and detect them separately. In this process, multiple sample boxes are required. In addition, to improve the detection efficiency, general sample detections are transported centrally and batch-detected. In this process, sample boxes of multiple patients will be transported together. So the current problems are that the number of sample boxes sent for inspection is large, the transportation is troublesome and inefficient, and the classification is unclear. When detecting, the samples are prone to confusion, resulting in inaccurate detection results.

[0040] Refer to Figure 1 and Figure 2, in an embodiment of the present invention application, a tissue sample preservation container is disclosed, which includes a first vessel 10, a second vessel 20 and a lid 30. A first storage groove with an open upper end is provided on the first vessel 10; the second vessel 20 is connected to the first vessel 10 and covers the first storage groove; and, a second storage groove with an open upper end is provided on the second vessel 20; the lid 30 is connected to the second vessel 20 and covers the second storage groove; both the first storage groove and the second storage groove are used to accommodate formalin solution, transport medium or carbon powder medium to preserve tissue samples.

[0041] The tissue sample preservation container disclosed in this embodiment is sequentially connected by the first vessel 10, the second vessel 20 and the lid 30, and the whole container is integrated. During use, tissue samples from different positions can be placed in the first storage groove and the second storage groove respectively, so as to centrally store multiple samples of one patient, which is convenient for centralized submission for inspection and improves the inspection efficiency.

[0042] Specifically, when batch-inspecting multiple tissue samples of multiple patients, multiple samples of the same patient are put together and transported in one tissue sample preservation container, while samples of different patients are stored in different tissue sample preservation containers. Therefore, the classification is clear and not easy to be confused, further improving the inspection efficiency and the effectiveness of the inspection.

[0043] In this embodiment, the second vessel 20 is connected to the first vessel 10 and covers the first storage groove, so the second vessel 20 serves to seal the first storage groove; a second storage groove is provided on the second vessel 20 and is sealed by the lid 30. Therefore, during use, formalin solution, transport medium or carbon powder medium can be injected into the first storage groove and the second storage groove according to the needs of sample preservation.

[0044] Specifically, formalin solution is an aqueous solution containing 37%-40% formaldehyde, which can well preserve biological specimens to meet the needs of long-distance sample transportation. However, formalin solution has antiseptic and bactericidal effects and inactivates germs. In the detection of some tissue samples, it is necessary to detect the germs on the tissue, so it cannot be placed in formalin solution. At this time, the transport medium can be filled in the first storage groove and the second storage groove to maintain the healthy state of microorganisms and cells and adapt to the working scenario of long-distance sample transportation. In some other cases, in order to avoid the adverse effects of harmful substances or pollutants, carbon powder medium can be filled in the first storage groove and the second storage groove, and activated carbon is used to adsorb harmful substances, thereby reducing the situation where microorganisms or cells are adversely affected.

[0045] In summary, the tissue sample storage container disclosed in this embodiment can store multiple tissue samples simultaneously by centrally arranging multiple enclosed spaces, and can extend the storage time of the tissue samples by injecting formalin solution or culture medium, so as to centrally store and centrally transport multiple sampling samples of the same patient, shorten the transport time, reduce the probability of tissue sample spoilage, and improve the detection efficiency and the validity of the detection results.

[0046] Specifically, as another embodiment of the present application, it is disclosed that the caliber of the first storage groove is 5-10 cm; or, the caliber of the second storage groove is 5-10 cm; or, the caliber of the first storage groove and the caliber of the second storage groove are both 5-10 cm.

[0047] The caliber of the first storage groove and the caliber of the second storage groove disclosed in this embodiment can be any value between 5-10 cm or the range between any two values, such as 5 cm, 5.5 cm, 6.5 cm, 7 cm, 9 cm, 10 cm, etc. During the clinical sampling process, the tissue sample may be a liquid sample or a solid sample. The shape of the liquid sample can be variable and has low requirements for space. The length and width of the solid sample are generally about 3-5 cm. Therefore, in this embodiment, by setting the caliber of the first storage groove and the second storage groove to be 5-10 cm, the space is large enough to accommodate tissue samples of various sizes and meet the clinical needs.

[0048] As Figure 2 shown, as another embodiment of the present application, it is disclosed that a first connecting portion 11 is provided on the outer wall of the first vessel 10, a second connecting portion 21 is provided at the bottom of the second vessel 20, and the second connecting portion 21 is detachably connected to the first connecting portion 11. A third connecting portion 22 is provided on the outer wall of the second vessel 20, a fourth connecting portion 31 is provided on the cover body 30, and the third connecting portion 22 is detachably connected to the fourth connecting portion 31.

[0049] In this embodiment, the detachable connection between the first vessel 10 and the second vessel 20 is realized through the first connecting portion 11 and the second connecting portion 21, and the detachable connection between the second vessel 20 and the cover body 30 is realized through the third connecting portion 22 and the fourth connecting portion 31, making the use of the container more flexible. The first vessel 10 and the second vessel 20 can be combined and used alone, the second vessel 20 and the cover body 30 can be combined and used alone, or the first vessel 10, the second vessel 20 and the cover body 30 can be combined and used together. Therefore, it can adapt to a variety of working scenarios.

[0050] For example, in this embodiment, the first container 10 and the second container 20 are both provided in a cylindrical shape. The first connecting portion 11 and the second connecting portion 21 can be provided with a threaded connection or a snap connection. The structures of the third connecting portion 22 and the fourth connecting portion 31 are the same as those of the first connecting portion 11 and the second connecting portion 21, so that the overall effect of quick disassembly and assembly can be achieved for convenient use.

[0051] Again, Figure 2 As shown, as another embodiment of the present application, a first assembly groove 23 is formed on one side of the second container 20 facing the first container 10. The first assembly groove 23 is used for inserting the first container 10; the second connecting portion 21 is provided on the side wall of the first assembly groove 23; the first connecting portion 11 is provided at a position on the first container 10 opposite to the second connecting portion 21; a second assembly groove 32 is formed on one side of the cover body 30 facing the second container 20. The second assembly groove 32 is used for inserting the second container 20; the fourth connecting portion 31 is provided on the side wall of the second assembly groove 32; the third connecting portion 22 is provided at a position on the second container 20 opposite to the fourth connecting portion 31.

[0052] In this embodiment, the first container 10 disclosed is inserted into the first assembly groove 23. The opening of the first storage groove is wrapped by the first assembly groove 23, thereby improving the airtightness. When formalin solution or culture medium is loaded into the first storage groove, the problem of liquid leakage can be avoided, and the internal anaerobic environment can be better maintained, slowing down tissue oxidation. Similarly, the second assembly groove 32 is used for inserting the second container 20 to improve the airtightness of the second storage groove.

[0053] Specifically, the first container 10, the second container 20, and the cover body 30 disclosed in this embodiment are sequentially stacked. The insertion connection is realized by setting the first assembly groove 23 and the second assembly groove 32, making the connection between the first container 10 and the second container 20 more firm, and the connection between the second container 20 and the cover body 30 more firm. The entire container is integrated into one body, with high stability during transportation and not easily disassembled.

[0054] In addition, in this embodiment, the second connecting portion 21 can be provided on the side wall of the first assembly groove 23, facing the outer wall of the first container 10, and the fourth connecting portion 31 is provided on the side wall of the second assembly groove 32, facing the outer wall of the second container 20. Therefore, the connection part fits more closely, further improving the airtightness of the first storage groove and the second storage groove.

[0055] Such as Figure 1As shown, as another embodiment of the present application, it is disclosed that the tissue sample preservation container includes an air extraction device 40; the second container 20 fits the opening of the first storage groove to form a first sealed cavity; a first negative pressure pipeline 24 and a first suction pipeline 25 are provided on the second container 20; one end of the first negative pressure pipeline 24 extends into the first sealed cavity, and the other end is connected to the air extraction device 40; one end of the first suction pipeline 25 extends into the first sealed cavity, and a first sealing rubber cap 26 is provided at the other end; the cover body 30 fits the opening of the second storage groove to form a second sealed cavity; a second negative pressure pipeline 33 and a second suction pipeline 34 are provided on the cover body 30; one end of the second negative pressure pipeline 33 extends into the second sealed cavity, and the other end is connected to the air extraction device 40; one end of the second suction pipeline 34 extends into the second sealed cavity, and a second sealing rubber cap 35 is provided at the other end.

[0056] The air extraction device 40 disclosed in this embodiment includes, but is not limited to, a vacuum pump. Connecting the air extraction device 40 to the first negative pressure pipeline 24 and the second negative pressure pipeline 33 can perform air extraction simultaneously, improving work efficiency and simplifying the structure. In another implementation manner of this embodiment, valves can also be provided on the first negative pressure pipeline 24 and the second negative pressure pipeline 33 to facilitate independent control of the negative pressure in the two sealed cavities.

[0057] Specifically, the first negative pressure pipeline 24 and the second negative pressure pipeline 33 are arranged to connect to the air extraction device 40 to extract the air in the first storage groove and the second storage groove, so as to form an anaerobic environment in the first storage groove and the second storage groove, further slowing down the oxidation and corruption of the tissue sample.

[0058] Specifically, the first suction pipeline 25 and the second suction pipeline 34 are arranged to facilitate the feeding of tissue samples. Similar to the current blood sample collection method, first, a negative pressure is formed in the first sealed cavity and the second sealed cavity through air extraction, and then medical staff clamp the tissue sample and pierce the first sealing rubber cap 26 or the second sealing rubber cap 35 to feed the tissue sample; both the first sealing rubber cap 26 and the second sealing rubber cap 35 can be made of rubber material, which can tightly wrap the clamp, thereby maintaining the negative pressure state in the first sealed cavity and the second sealed cavity. After the tissue sample enters the first sealed cavity or the second sealed cavity, air extraction can be performed again to form an anaerobic environment and preserve the tissue sample for a longer time.

[0059] In summary, in this embodiment, the first suction pipeline 25 and the second suction pipeline 34 are arranged to facilitate the feeding of tissue samples on the basis of maintaining a sealed environment, and the first negative pressure pipeline 24 and the second negative pressure pipeline 33 are arranged to timely extract the air in the first sealed cavity and the second sealed cavity, thereby extending the preservation time of the tissue sample.

[0060] For example, when the first storage groove is filled with carbon powder culture medium, the tissue sample enters the first sealed chamber from the first suction pipe 25 and is surrounded by carbon powder. The carbon powder adsorbs some useless impurities such as blood clots of the tissue and maintains an anaerobic environment around the tissue to achieve oxygen removal storage.

[0061] As Figure 1 and Figure 2 shown, in another embodiment of the present application, it is disclosed that a first sealing rubber sleeve is provided on the first negative pressure pipe 24, and a second sealing rubber sleeve is provided on the second negative pressure pipe 33. After the air extraction is completed, the first negative pressure pipe 24 can be disconnected from the air extraction device 40, and the first sealing rubber sleeve is put on to isolate the outside air; at the same time, the second negative pressure pipe 33 is disconnected from the extraction device, and the second sealing rubber sleeve is put on to isolate the outside air. On the basis of maintaining the first sealed chamber and the second sealed chamber in a sealed state, separating the air extraction device 40 from the first vessel 10 and the second vessel 20 is beneficial to reducing the volume and facilitating transportation.

[0062] Specifically, the first sealing rubber cap 26, the second sealing rubber cap 35, the first sealing rubber sleeve, and the second sealing rubber sleeve disclosed in this embodiment can all be formed of the same rubber or silica gel material.

[0063] As Figure 2 shown, as another embodiment of the present application, it is disclosed that the tissue sample storage container includes a first sampling swab 50, and a first chuck 51 for clamping the tissue sample is provided at the front end of the first sampling swab 50; a first end cap 52 is provided at the rear end of the first sampling swab 50; wherein, the first chuck 51 can pierce the first sealing rubber cap 26 to insert into the first sealed chamber, and the first end cap 52 is nested on the first suction pipe 25.

[0064] In this embodiment, the tissue sample is clamped by the first sampling swab 50 to facilitate stably feeding the tissue sample into the first sealed chamber. Specifically, the front end of the first sampling swab 50 is two oppositely arranged clamping plates, and the two clamping plates can rotate towards each other to clamp the tissue sample, and a puncture needle or a pointed head can be provided at the front end of the clamping plate. When feeding the tissue sample, first pierce the first sealing rubber cap 26 through the puncture needle or the pointed head to form a through channel, and then the first chuck 51 passes through this channel and enters the first sealed chamber; and as the first chuck 51 enters the first sealed chamber, the first end cap 52 covers the first suction pipe 25, thereby stabilizing the first sampling swab 50 and keeping the tissue sample stable in the first sealed chamber for easy transportation. During detection, as long as the first sampling swab 50 is withdrawn in the reverse direction, the tissue sample can be taken out, improving the detection efficiency.

[0065] Again, as Figure 2As shown in the figure, as another embodiment of the present application, it is disclosed that the tissue sample preservation container includes a second sampling swab 60, and a second chuck 61 for clamping the tissue sample is provided at the front end of the second sampling swab 60; a second end cap 62 is provided at the rear end of the second sampling swab 60; wherein, the second chuck 61 can pierce the second sealing rubber cap 35 to insert into the second sealed cavity, and the second end cap 62 is nested on the second suction pipe 34.

[0066] The second sampling swab 60 disclosed in this embodiment can adopt exactly the same structure as the above-mentioned first sampling swab 50, so as to maintain the closed state of the second sealed cavity, smoothly send in or take out the tissue sample at the same time, and improve the convenience of operation.

[0067] Another example Figure 2 As shown in the figure, as another embodiment of the present application, it is disclosed that a hollow first hanging basket 27 is provided on the second container 20, and the first hanging basket 27 is arranged in the first sealed cavity; a hollow second hanging basket 36 is provided on the cover body 30, and the second hanging basket 36 is arranged in the second sealed cavity; wherein, both the first hanging basket 27 and the second hanging basket 36 are used for storing carbon powder.

[0068] In this embodiment, the first sealed cavity and the second sealed cavity disclosed are used to put tissue samples that may carry blood clots or germs. By setting the first hanging basket 27 and the second hanging basket 36 and putting in carbon powder, impurities useless for detection can be adsorbed. Moreover, the first hanging basket 27 disclosed in this embodiment is arranged on the second container 20. When the first container 10 is separated from the second container 20, the first hanging basket 27 is also withdrawn from the first storage groove, taking away the impurities to avoid affecting the test results. Similarly, when the second container 20 is separated from the cover body 30, the second hanging basket 36 leaves the second storage groove, which can also reduce the influence on the test results.

[0069] Specifically, as another embodiment of the present application, it is disclosed that the height value of the first hanging basket 27 is equal to the depth value of the first storage groove; or, the height value of the second hanging basket 36 is equal to the depth value of the second storage groove. In this embodiment, the first hanging basket 27 extends into the first storage groove, and its height is equal to the depth of the first storage groove, and it can extend to the bottom of the first storage groove, so as to ensure that the carbon powder is immersed in the solution or the culture medium and play an adsorption role. Similarly, the second hanging basket 36 can extend to the bottom of the second storage groove to ensure the adsorption effect.

[0070] Such as Figure 1 and Figure 2As shown, as another embodiment of the present application, it is disclosed that the second container 20 includes a first sample placing unit 28 and a second sample placing unit 29 which are stacked. One side of the first sample placing unit 28 is connected to the first container 10, and a third storage groove is formed on the other side. One side of the second sample placing unit 29 covers the third storage groove, and a second storage groove is formed on the other side.

[0071] In this embodiment, the disclosed second container 20 can be set as a multi-layer structure, and a third storage groove is provided to further increase the storage space on the container, so as to adapt to more sample quantities and expand the usage scenarios of the container. Specifically, two or more second sample placing units 29 can be selectively assembled according to the quantity of the collected samples and stacked in sequence, that is, there are two or more third storage grooves, so that more samples can be placed on the entire container.

[0072] As Figure 1 shown, in this embodiment, a third negative pressure pipeline 281 and a third suction pipeline 282 can be provided on the first sample placing unit 28, and the third negative pressure pipeline 281 is connected to the air extraction device 40, so that the negative pressure state in the third storage groove can be maintained, forming the same storage environment as that in the first storage groove and the second storage groove.

[0073] In summary, the present application discloses a tissue sample preservation container, including a first container 10, a second container 20 and a cover body 30. An upper-end open first storage groove is provided on the first container 10. The second container 20 is connected to the first container 10 and covers the first storage groove. And an upper-end open second storage groove is provided on the second container 20. The cover body 30 is connected to the second container 20 and covers the second storage groove. Both the first storage groove and the second storage groove are used to accommodate formalin solution, transport medium or carbon powder medium to preserve tissue samples. The entire container disclosed in this embodiment is integrated. When in use, tissue samples at different positions can be placed in the first storage groove and the second storage groove respectively, so as to centrally store multiple samples of one patient for centralized submission for inspection, improve the inspection efficiency, and can store samples of different patients separately without being easily confused, so as to further improve the inspection efficiency and the effectiveness of the inspection.

[0074] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0075] It should be noted that the present invention introduces the specific structure and working principle of the present invention by taking the tissue sample preservation container as an example, but the application of the present invention is not limited to the tissue sample preservation container, and can also be applied to the inspection, production and use of other similar workpieces.
