Description

Technical Field

[0001] The present application relates to the field of biological sample storage, and in particular to a test tube sleeve for storing biological samples. Background Art

[0002] According to Chinese law, if the breath alcohol test result exceeds 80mg / 100ml, it is suspected of drunk driving and blood test is required. The result of the blood test is used as the basis for punishment. In the process of handling drunk driving cases, standardized and legal blood sample identification opinions are a powerful weapon to effectively combat drunk driving. Standardizing the law enforcement process of drunk driving investigation and punishment, preventing law enforcement risks, and establishing a sound blood sample extraction, storage, and inspection management system are important tasks in the current legal system construction of law enforcement departments.

[0003] Biological organisms are in a sterile and constant temperature state in the human body. Once they leave the human body, they will come into contact with bacteria and other microorganisms in the outside world and become corrupt. After biological corruption, ethanol will be produced, which will affect the identification results. Therefore, it is necessary to ensure that the blood sample, which is an important piece of evidence, does not become corrupt before identification, otherwise it will lose its role as evidence. From a biomedical point of view, storing blood samples in a low-temperature environment can reduce the reproduction of bacteria and other microorganisms in the test tube, reduce the occurrence of biological corruption, and thus ensure the accuracy and reliability of blood sample identification results. To this end, according to the "Technical Specifications for Human Biological Collection for Road Traffic Law Enforcement" (GA / T1556-2019) of the Ministry of Public Security: The extracted blood samples should be stored in the refrigerator, and the refrigeration temperature should be kept at a low temperature of 2℃ to 8℃; after the test is completed, the re-examination sample should be placed in a low-temperature refrigerator for freezing, and the freezing temperature should be kept between -10℃ and -18℃, with a shelf life of not less than 3 months; the biological sample should be kept at a low temperature during the inspection process.

[0004] In the prior art, sealed bags are usually used to seal blood samples, such as the sealed bags in the Chinese patent document with application number 202022176831.8. The sealed blood samples are placed in a refrigerator, that is, the test tubes containing blood samples are placed in sealed bags, and a seal is affixed to the sealed bags to prevent the blood samples from being opened or replaced without permission, thereby ensuring the validity of the evidence. However, the sealed bags are large in size and irregular in shape, which not only takes up a large space and is difficult to automatically access, but also requires manual management, with disadvantages such as low space utilization and low management efficiency. At the same time, existing sealed bags are generally made of paper or soft plastic, which can easily be used by people to replace blood samples by entering the blood sample tubes through fine needle puncture, resulting in the destruction of the authenticity of the evidence, which is not conducive to the management of drunk driving, and it is necessary to make improvements.

[0056] Embodiment 1:

[0057] See also Figures 1 to 5As shown, the embodiment of the present application provides a test tube sleeve 80a for storing biological samples, and the test tube sleeve 80a has an axial direction D1, and the axial direction D1 of the test tube sleeve 80a is referred to as the axial direction D1 of the test tube sleeve 80a. It should be noted that the axial direction D1 of the test tube sleeve 80a can also be understood as the height direction D1 of the test tube sleeve 80a, or as the vertical direction D1 of the test tube sleeve 80a. It should be understood that when the test tube sleeve 80a is equipped with a test tube 91a, the axial direction D1 of the test tube sleeve 80a can also be understood as the axial direction of the test tube 91a.

[0058] The test tube sleeve 80a also has a circumferential direction D2. Exemplarily, the axial direction D1 of the test tube sleeve 80a and the plane where the circumferential direction D2 of the test tube sleeve 80a lies are substantially perpendicular.

[0059] The test tube sleeve 80a also has a radial direction D3. When the test tube sleeve 80a is equipped with the test tube 91a, the radial direction D3 of the test tube sleeve 80a can also be understood as the radial direction of the test tube 91a.

[0060] Exemplarily, at least two structural members can be connected along the axial direction D1 of the test tube sleeve 80a to form the test tube sleeve 80a. It should be noted that at least two structural members can also be connected along the radial direction D3 of the test tube sleeve 80a to form the test tube sleeve 80a. The number of structural members of the test tube sleeve 80a in the embodiment of the present application is illustrated by taking two as an example. It should be understood that the number of structural members of the test tube sleeve 80a in the embodiment of the present application is not limited to two, and three or other numbers are also within the protection scope of the embodiment of the present application. The following exemplary descriptions are respectively given in conjunction with the schematic diagrams of different test tube sleeves.

[0061] Please continue reading Figures 1 to 5 In the embodiment of the present application, the test tube sleeve 80a includes a shell 81a and a cover 82a. The shell 81a and the cover 82a are connected along the axial direction D1 of the test tube sleeve 80a, or the shell 81a and the cover 82a are connected along the vertical direction D1 of the test tube sleeve 80a, or the shell 81a and the cover 82a are connected along the height direction D1 of the test tube sleeve 80a.

[0062] The housing 81a has a first accommodating chamber 813a and a first opening 814a that are interconnected, and the first accommodating chamber 813a is used to accommodate at least a portion of a test tube 91a containing a blood sample. The embodiment of the present application is exemplified by taking the first accommodating chamber 813a as an example of accommodating a portion of a test tube 91a containing a blood sample. It should be understood that the first accommodating chamber 813a can also be used to accommodate the entire test tube 91a containing a blood sample. It is understandable that the test tube 91a containing a blood sample can be loaded into the first accommodating chamber 813a from the first opening 814a.

[0063] The shell 81a and the cover 82a are detachably connected, that is, the shell 81a and the cover 82a can be connected together, and the shell 81a and the cover 82a can be separated. When the shell 81a and the cover 82a are connected, the cover 82a covers the first opening 814a, and the shell 81a and the cover 82a together enclose a receiving space 89a for receiving the test tube 91a containing the blood sample, and the receiving space 89a includes a first receiving cavity 813a.

[0064] Exemplarily, the cover 82a has a second accommodating chamber 823a and a second opening 824a that are interconnected, and the second accommodating chamber 823a is used to accommodate a portion of the test tube 91a containing the blood sample. It is understandable that a portion of the test tube 91a containing the blood sample can be loaded into the second accommodating chamber 823a from the second opening 824a. When the shell 81a and the cover 82a are connected, the shell 81a covers the second opening 824a, and the first accommodating chamber 813a and the second accommodating chamber 823a are connected to form a accommodating space 89a. Specifically, the first accommodating chamber 813a and the second accommodating chamber 823a are connected through the first opening 814a and the second opening 824a to form a accommodating space 89a.

[0065] Exemplarily, the shell 81a and the cover 82a are both made of hard materials. Compared with paper bags or plastic bags, the shell 81a and the cover 82a made of hard materials are not easily deformed, are easy to be clamped, and can be clamped by mechanical equipment such as a manipulator, so that automated management can be achieved, and the efficiency of managing blood samples can be improved. At the same time, the shell 81a and the cover 82a made of hard materials are not easy for people to enter the blood sample tube through fine needle puncture to replace the blood sample, which can more effectively ensure the authenticity of the evidence.

[0066] It should be noted that the accommodation space 89a formed by the hard material shell 81a and the cover 82a only needs to be able to accommodate the test tube 91a containing the blood sample. The test tube sleeve 80a of the embodiment of the present application can accommodate the test tube 91a as long as it is slightly larger than the test tube 91a. Moreover, the test tube sleeve 80a is not easy to deform. The space occupied by it after being stored in the predetermined position is constant, and the space occupied will not increase due to deformation. Therefore, the test tube sleeve 80a occupies a small space and can more effectively utilize the storage space. Among them, the test tube sleeve 80a is stored in a predetermined position, such as a sample storage unit of an automatic storage and retrieval device for blood samples. Therefore, the test tube sleeve 80a of the embodiment of the present application occupies a small space and can more effectively utilize the storage space.

[0067] In this embodiment, the test tube sleeve 80a is mainly used to accommodate one test tube 91a. In the process of blood drawing, 1-3 test tubes of blood samples are usually drawn from the subject. In order to facilitate the management of blood samples, several test tubes of the same subject can be placed in the same test tube sleeve 81a for storage. Exemplarily, when the number of test tubes 91a to be stored in a test tube sleeve 80a is one, the shape of the accommodating space 89a of the test tube sleeve 81a matches the external shape of the one test tube 91a; when the number of test tubes 91a to be stored in a test tube sleeve 80a is two, the shape of the accommodating space 89a of the test tube sleeve 81a matches the external shape of the two test tubes 91a when they are parallel to each other and arranged side by side; when the number of test tubes 91a to be stored in a test tube sleeve 80a is three, the shape of the accommodating space 89a of the test tube sleeve 81a may match the external shape of the three test tubes 91a when they are parallel to each other and arranged side by side, or may match the external shape of the three test tubes 91a when they are parallel to each other and arranged adjacent to each other.

[0068] Exemplarily, the test tube sleeve 80a has a top end 87a and a bottom end 88a. Specifically, the shell 81a and the cover 82a are both cylindrical with one end open and the other end closed. The closed end of the shell 81a is the bottom 88a of the test tube sleeve 80a, and the closed end of the cover 82a is the top 87a of the test tube sleeve 80a. The connection between the shell 81a and the cover 82a is the middle part of the test tube sleeve 80a. The opening direction of the shell 81a and the cover 82a is consistent with the axial direction of the test tube 91a. When the test tube 91a is loaded, the shell 81a and the cover 82a are sleeved on the test tube 91a by the upper and lower ends of the test tube 91a, so that the test tube 91a is accommodated in the accommodation space 89a enclosed by the shell 81a and the cover 82a.

[0069] In order to prevent the test tube sleeve 80a from being unauthorizedly disassembled, causing the sample to be damaged, lost or replaced, it is also necessary to paste a seal 92a at the connection between the shell 81a and the cover 82a. In order to facilitate the pasting of the seal 92a, in this embodiment, the outer surface of the side wall of the shell 81a is provided with a first seal pasting area 811a adjacent to the cover 82a, and the outer surface of the side wall of the cover 82a is provided with a second seal pasting area 821a adjacent to the shell 81a. The first seal pasting area 811a and the second seal pasting area 821a are smoothly connected, that is, the second seal pasting area 821a together forms a seal pasting area 85a, and the seal pasting area 85a is a smooth and continuous plane or curved surface, so as to facilitate the pasting of the seal 92a. That is, the seal 92a is pasted on the first seal pasting area 811a and the second seal pasting area 821a at the same time, and the seal 92a covers the intersection 86a between the shell 81a and the cover 82a. The seal 92a can be a common seal or an anti-counterfeiting seal. For example, after the anti-counterfeiting seal is pasted on the first seal pasting area 811a and the second seal pasting area 821a, it cannot be completely torn off. If the test tube cover 80a is forcibly opened, the sealing seal will also be damaged. Therefore, by checking whether the seal 92a is intact, it can be determined whether the test tube cover 80a has been opened to ensure the authenticity of the blood sample used as evidence. It should be understood that the seal 92a covers the junction 86a between the shell 81a and the cover 82a. If the seal 92a is not damaged, it is determined that the test tube cover 80a has not been opened. If the seal 92a is damaged, it is determined that the test tube cover 80a has been opened.

[0070] Exemplarily, the first seal sticking area 811a surrounds the shell 81a along the circumferential direction D2 of the test tube sleeve 80a, and the second seal sticking area 821a surrounds the cover 82a along the circumferential direction D2 of the test tube sleeve 80a.

[0071] Exemplarily, the outer surface of the junction 86a between the shell 81a and the cover 82a has a smooth transition and is coplanar.

[0072] like Figure 3 As shown, the seal 92a needs to be printed or handwritten with the contents related to the blood sample. Therefore, in order to increase the area of ​​the seal 92a so as to record the contents related to the blood sample, in this embodiment, the seal 92a is arranged around the circumferential direction D2 of the test tube sleeve 80a and is connected end to end, that is, the length of the seal 92a is equal to the outer circumference of the seal pasting area 85a. In other embodiments, the length of the seal 92a can also be greater than or equal to the outer circumference of the seal pasting area 85a. Exemplarily, a plurality of recording areas 921a are arranged on the seal 92a, and each recording area 921a can record the corresponding information of the blood sample.

[0073] In order to facilitate the assembly of the housing 81a and the cover 82a, in this embodiment, the housing 81a and the cover 82a are connected by threads. In other embodiments, the housing 81a and the cover 82a can also be connected by other detachable connection methods such as bonding, interference fit, etc.

[0074] In order to make full use of space, when storing blood samples, multiple test tube sleeves 80a containing blood samples need to be densely stored together. If the outer shape of the test tube sleeve 80a is a cylindrical shape with equal diameters at all locations, it will be difficult for the manipulator of the blood sample automatic storage and retrieval device to clamp the test tube sleeve 80a. If the spacing between the test tube sleeves 80a is increased, it will be convenient for the manipulator to clamp the test tube sleeve 80a, but the space utilization rate will be reduced. In order to solve the above technical problems, in this embodiment, a clamping area 822a is provided on the outer surface of the side wall of the top end 87a of the test tube sleeve 80a. The diameter of the clamping area 822a is smaller than the diameter of other positions on the test tube sleeve 80a, and is used for the manipulator to clamp.

[0075] Specifically, a clamping area 822a is provided on the outer surface of the side wall of the cover 82a of the test tube sleeve 80a at one end away from the housing 81a, and the diameter of the clamping area 822a is smaller than the diameter of other positions on the cover 82a, thereby forming a structure of the cover 82a being larger at the bottom and smaller at the top. A clamping portion 84a is formed on the clamping area 822a for cooperating with a manipulator, thereby providing the manipulator with sufficient operating space when the test tube sleeves 80a are densely stored.

[0076] In other embodiments, the outer shape of the test tube sleeve 80a may also be set to a cylindrical shape with equal diameters at all locations to save production costs.

[0077] Embodiment 2:

[0078] See also Figures 6 to 10 As shown, compared with Example 1, the difference between the test tube sleeve 80b and the test tube sleeve 80a in the embodiment of the present application at least includes: the shell 81b and the cover 82b of the test tube sleeve 80b are connected along the radial direction D6 of the test tube sleeve 80b. It should be understood that the test tube sleeve 80b has an axial direction D4, a circumferential direction D5 and a radial direction D6, wherein the axial direction D4 can refer to the axial direction D1, the circumferential direction D5 can refer to the circumferential direction D2, and the radial direction D6 can refer to the radial direction D3, which will not be repeated here.

[0079] For example, the shell 81b and the cover 82b are buckled in the left-right direction, that is, the opening direction of the shell 81b and the cover 82b is consistent with the radial direction of the test tube 91b. Therefore, when the test tube 91b is loaded, the shell 81b and the cover 82b are buckled on the opposite sides of the test tube 91b, so that the test tube 91b is accommodated in the accommodation space enclosed by the shell 81b and the cover 82b.

[0080] The shell 81b has a first accommodating cavity 813b and a first opening 814b that are interconnected, and the cover 82b has a second accommodating cavity 823b and a second opening 824b that are interconnected. When the shell 81b and the cover 82b are connected, the directions of the first opening 814b and the second opening 824b are consistent with the radial direction D6 of the test tube 91b, and the shell 81b and the cover 82b are enclosed together to form an accommodating space, or the first accommodating cavity 813b and the second accommodating cavity 823b are interconnected to form an accommodating space.

[0081] like Figure 7 and Figure 8 As shown, the connection 86b of the shell 81b and the cover 82b is provided with a mutually interlocking structure to prevent others from inserting a fine needle through the connection 86b to extract and replace the blood sample in the test tube sleeve. Exemplarily, the inner side of the side wall of the shell 81b is provided with a recessed structure 815b, and the inner side of the side wall of the cover 82b is provided with a raised structure 825b, and the raised structure 825b can be placed in the recessed structure 815b to achieve the mutual interlocking of the connection 86b of the shell 81b and the cover 82b.

[0082] The differences between the test tube sleeve 80b of the embodiment of the present application and the test tube sleeve 80a in Example 1 include: the top end 87b of the test tube sleeve 80b is formed by the top end of the shell 81b and the top end of the cover 82b, and the bottom end 88b of the test tube sleeve 80b is formed by the bottom end of the shell 81b and the bottom end of the cover 82b.

[0083] The difference between the test tube sleeve 80b of the embodiment of the present application and the test tube sleeve 80a in Example 1 includes: the connection 86b between the shell 81b and the cover 82b extends from the top end 87b of the test tube sleeve 80b to the bottom end 88b of the test tube sleeve 80b, while the connection 86 between the shell 81a and the cover 82a is located in the middle position of the test tube sleeve 80a, or between the top end 87a and the bottom end 88a of the test tube sleeve 80a.

[0084] The difference between the test tube sleeve 80b of the embodiment of the present application and the test tube sleeve 80a in the embodiment 1 includes: the first seal sticking area 811b of the shell 81b and the second seal sticking area 821b of the cover 82b do not surround the test tube sleeve 80b, the first seal sticking area 811b and the second seal sticking area 821b are smoothly connected to form a seal sticking area 85b together, and the seal sticking area 85b surrounds the test tube sleeve 80b. Exemplarily, except for the recessed structure 815b of the shell 81b and the raised structure 825b of the cover 82b, the shape and size of the shell 81b and the cover 82b are basically the same. The seal 92b can be pasted on the first seal sticking area 811b and the second seal sticking area 821b to cover a part of the intersection 86b. Among them, the seal 92b can be specifically referred to the seal 92a, which will not be repeated here.

[0085] The difference between the test tube sleeve 80b of the embodiment of the present application and the test tube sleeve 80a in Example 1 includes: the clamping area 822b of the test tube sleeve 80b is formed by a part of the shell 81b and a part of the cover 82b, or the clamping portion 84b is formed by a part of the shell 81b and a part of the cover 82b.

[0086] It should be noted that other structures of the test tube sleeve 80b can refer to the test tube sleeve 80a, such as the smooth transition and coplanarity of the junction 86b between the shell 81b and the shell 82b, which will not be repeated in the embodiment of the present application.

[0087] Embodiment 3:

[0088] See also Fig.11 and Fig.12 As shown, compared with Example 2, the differences between the test tube sleeve 80c in the embodiment of the present application and the test tube sleeve 80c at least include: the test tube sleeve 80c also includes a movable connecting portion 83c connecting the shell 81c and the cover 82c. When the shell 81c and the cover 82c are injection molded, the two parts are connected through a small connecting area and can be opened and closed a certain number of times along the connecting area. The small connecting area is the movable connecting portion 83c.

[0089] Therefore, when the test tube sleeve 80c is opened, the shell 81c and the cover 82c are not separated, and are connected by the movable connection part 83c.

[0090] Exemplarily, the housing 81c and the cover 82c are movably connected to switch between an open state and a closed state. When the housing 81c and the cover 82c are in a closed state, the cover 82c covers the first opening 814c. The housing 81c and the cover 82c together enclose a storage space for accommodating a test tube 91c containing a blood sample, wherein the storage space includes a first storage chamber 813c. Exemplarily, when the housing 81c and the cover 82c are in a closed state, the housing 81c covers the second opening 824c, and the storage space includes a first storage chamber 813c and a second storage chamber 823c.

[0091] The shell 81c and the cover 82c are connected via a rotating shaft or a movable connecting portion 83c. The cover 82c can rotate relative to the shell 81c via the rotating shaft or the movable connecting portion 83c, so that the shell 81c and the cover 82c can be switched between an open state and a closed state.

[0092] Among them, other structures of the test tube sleeve 80c can refer to the test tube sleeve 80b, such as the first seal adhesive area 811b, the second seal adhesive area 821b, the clamping area 822b, the junction 86b, the top end 87b and the bottom end 88b of the test tube sleeve 80b, and the embodiments of the present application will not be repeated here.

[0093] Embodiment 4:

[0094] See also Figure 13-Figure 16 Compared with Example 1, the main difference between the test tube sleeve 80d of this embodiment and the test tube sleeve 80a is that the test tube sleeve 80d is provided with a movable connection portion 83d, and the shell 81d and the cover body 82d are connected through the movable connection portion 83d.

[0095] In order to prevent the test tube 91d in the test tube sleeve 80d from hindering the opening and closing of the test tube sleeve 80d, the length of the cover 82d is smaller than the length of the housing 81d. When the test tube 91d is loaded, the cover 82d is first opened, the test tube 91d is placed in the housing 81d, and then the cover 82d is closed.

[0096] Exemplarily, the length of the cover 82d is much smaller than the length of the shell 81d. It should be understood that the length of the shell 81d and the length of the cover 82d are both the lengths along the axial direction of the test tube sleeve 80d. The axial direction of the test tube sleeve 80d can refer to the axial direction D1 of the test tube sleeve 80a, which will not be repeated here.

[0097] Since the cover 82d is small, the surface area of ​​its side wall is small, and the seal 92d needs to occupy a larger part of its surface area. If the clamping area 822d is also set on the cover 82d, the manipulator of the blood sample automatic access device may clamp the seal 92d, causing the seal 92d to be contaminated and damaged. In order to prevent the contamination and damage of the seal 92d, in this embodiment, the top 87d is located at the end of the shell 81d away from the cover 82d, the bottom 88b is located at the end of the cover 82d away from the shell 81d, and the clamping area 822d is set at the top 87d. The clamping area 822d can be understood as the clamping portion 85d.

[0098] like Figures 14 to 16 As shown, the connection between the shell 81d and the cover 82d is provided with a mutually interlocking structure to prevent others from inserting a fine needle through the connection 86d to extract and replace the blood sample in the test tube sleeve. Exemplarily, the inner side of the side wall of the shell 81d is provided with a protruding structure 815d, and the inner side of the side wall of the cover 82d is provided with a concave structure 825d, and the protruding structure 815d can be placed in the concave structure 825d to achieve the mutual interlocking of the connection between the shell 81d and the cover 82d.

[0099] Among them, other structures of the test tube cover 80d can refer to the test tube cover 80a, such as the seal pasting area 85d of the test tube cover 80d, and the first seal pasting area 811d and the second seal pasting area 821d, can refer to the seal pasting area 85a, and the first seal pasting area 811a and the second seal pasting area 821a, which will not be repeated here. Among them, the seal 92d is pasted on the seal pasting area 85d, and the connection relationship between the seal 92d and the seal 92d pasted on the seal pasting area 85d can refer to the seal 92a, which will not be repeated here.

[0100] For another example, the accommodating space 89d, the first accommodating cavity 813d, the second accommodating cavity 823d, the first opening 814d and the second opening 824d of the test tube sleeve 80d can refer to the accommodating space 89a, the first accommodating cavity 813a, the second accommodating cavity 823a, the first opening 814a and the second opening 824a, which will not be described in detail. The test tube 91d can be accommodated in the accommodating space 89d.

[0101] The above embodiments only illustrate the storage of blood samples, but the test tube sleeve of the present invention can be used not only to store blood samples, but also to store other biological samples such as urine, saliva, hair, etc.

[0102] Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. At the same time, for technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
