Description

Technical Field

[0001] This application relates to the field of container handling technology, and in particular to a sample clip and related equipment. Background Technology

[0002] Sample holders are used to hold samples, facilitating their handling and placement, and for imaging observation in microscopic systems. In some scenarios, different types or categories of samples, such as biological cell samples, will be placed on different sample holders. These samples need to be identified and classified for subsequent operations.

[0003] Currently, the sample holder has a relatively simple function, only used to hold samples. Users need to identify and classify the samples on the sample holder themselves, which makes the identification and classification process less automated. Utility Model Content

[0004] This application provides a sample holder and related equipment to address the problem that existing sample holders have limited functionality.

[0005] In a first aspect, this application provides a sample holder, including a carrier body and a gripping part. One side of the carrier body has a carrier surface. The gripping part is disposed on the carrier surface, one end of which is connected to the carrier body, and the gripping part extends in a direction away from the carrier surface. The end face of the gripping part away from the carrier surface has a mounting groove. The opening of the mounting groove faces the side away from the carrier surface, and the mounting groove is used to set an identification label.

[0006] The sample holder provided in this application has a bearing surface on its main body that can be used to place samples. Since one end of the handle is connected to the main body and extends away from the bearing surface, the user can easily grasp the handle, thus facilitating the handling of the main body. Because the end face of the handle away from the bearing surface has a mounting groove, and the groove opening faces away from the bearing surface, when using the sample holder to hold samples, the corresponding identification label can be placed in the mounting groove. Subsequent testing instruments can directly identify the sample type through the identification label, eliminating the need for manual identification and input, thus improving automation. Furthermore, the orientation of the mounting groove opening facilitates identification, making identification more convenient.

[0007] In some embodiments, the sample holder further includes a holding cover. The holding cover is disposed on the end of the holding portion away from the bearing surface, and the holding cover covers the opening of the mounting groove.

[0008] In some embodiments, the groove wall of the mounting slot has a first limiting portion. The peripheral wall of the holding cover has a second limiting portion. The first limiting portion and the second limiting portion engage with each other.

[0009] In some embodiments, the gripping portion includes a first gripping portion and a second gripping portion. One end of the first gripping portion is connected to the support body. One end of the second gripping portion is connected to the other end of the first gripping portion, and the other end of the second gripping portion has a mounting groove. The vertical projection of the first gripping portion onto the support surface is located inside the vertical projection of the second gripping portion onto the support surface.

[0010] In some embodiments, the gripping part is detachably connected to the supporting body.

[0011] In some embodiments, the sample holder further includes a first fastener and a second fastener. One end of the first fastener is located on the side of the support body away from the handle, and the other end of the first fastener passes through the support body and extends into the mounting groove. The second fastener is located in the mounting groove, sleeved on the first fastener, and threadedly connected to the first fastener.

[0012] In some embodiments, the supporting body is a metal supporting body, and the holding part is a non-metallic holding part.

[0013] In some embodiments, the support surface has a placement groove. The sample holder also includes a clamping assembly. One end of the clamping assembly is movably connected to the support surface and located around the periphery of the placement groove. The other end of the clamping assembly is movable to a position opposite to the placement groove. The other end of the clamping assembly is also movable to a position offset from the placement groove.

[0014] In some embodiments, the clamping assembly includes a rotating shaft, a spring, and a limiting member. The rotating shaft is connected to a bearing surface. The spring is sleeved on the rotating shaft. One end of the limiting member is sleeved on the rotating shaft and located on the side of the spring away from the bearing surface. One side of the limiting member abuts against the spring, and the other side abuts against the rotating shaft. The limiting member is a sheet-like structure. The limiting member is inclined, and the distance between the limiting member and the bottom of the placement groove gradually decreases along the direction from the end of the limiting member near the spring to the end of the limiting member away from the spring. Alternatively, the limiting member is a block-like structure. The limiting member has an abutting protrusion, with the abutting protrusion located at the end of the limiting member away from the spring and on the side near the placement groove.

[0015] Secondly, this application provides an apparatus, including a testing device and any of the sample holders in the first aspect.

[0016] Since the equipment and instruments provided in this application include any of the sample clips in the first aspect, they can solve the same technical problems as the sample clips and achieve the same technical effects, they will not be described in detail here. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or system. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or system that includes that element.

[0022] In the following description, the terms "first," "second," etc., are used for descriptive convenience only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0023] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed mechanical connection, a detachable mechanical connection, or an integral part; or, "connection" may be a direct connection or an indirect connection through an intermediate medium.

[0024] Furthermore, unless otherwise explicitly specified and limited, the term "electrical connection" should be interpreted broadly. For example, "electrical connection" can be a direct electrical connection, such as physical contact and electrical conduction between two components; it can also be understood as the electrical connection between different components in a circuit structure through physical lines that can transmit electrical signals, such as copper foil or wires on a printed circuit board (PCB), to transmit electrical signals; or, "electrical connection" can be an indirect electrical connection between two components through an intermediate medium; or, "electrical connection" can be an electrical connection between two components in a way that is airtight or non-contact, such as an electrical connection between two components using capacitive coupling to transmit electrical signals.

[0025] In this application, two components are "parallel" to each other, which can mean completely parallel or approximately parallel within a certain acceptable deviation range. Furthermore, two components are "perpendicular" to each other, which can mean completely perpendicular or approximately perpendicular within a certain acceptable deviation range. The aforementioned acceptable deviation range can be determined by the limitations of the measurement system used by those skilled in the art.

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] A cell imaging analysis system is a biomedical instrument that integrates microscopic imaging technology and automated image analysis. It enables visual observation of cells and analysis based on cellular information. During observation and analysis, cell samples are typically placed on sample holders, which are then used to position the samples inside the cell imaging analysis system.

[0028] During observation and analysis, the cell imaging analysis system needs to analyze the types of samples in the sample holder so that the cell imaging analysis system can perform subsequent imaging, scanning, and mosaic operations.

[0029] However, the sample clips in the relevant technologies can only serve as carriers, and different types of sample clips have different cell sample areas, requiring operators to manually identify and input data, which makes it impossible to further automate the entire process of imaging and scanning.

[0030] Based on this, embodiments of this application provide a device or instrument, such as... Figure 1 and Figure 2 As shown, Figure 1 This is a front view of a device 1000 provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shows the structure of the device 1000 in the open state. The device 1000 may include a sample holder 100 and a detection instrument 200.

[0031] In this application, the specific type and structure of the detection instrument 200 are not further limited. For example... Figure 1 and Figure 2 As shown, the detection instrument 200 may include a detection housing 210 and a door 220. For example, the detection instrument 200 may specifically be a cell imaging analysis system.

[0032] The interior of the detection chamber 210 can form a detection chamber, which can be used to place samples for testing. The door 220 can be movably connected to the detection chamber 210 to open or close the detection chamber to ensure the sealing of the detection chamber during testing.

[0033] The sample holder 100 can be used to hold and place samples. For example, Figure 2 As shown, the sample holder 100 can be set in the detection chamber, and the sample can be placed on the sample holder 100 to hold the sample.

[0034] like Figure 3 As shown, Figure 3This is a schematic diagram of a sample holder 100 provided in an embodiment of this application. The sample holder 100 may include a support body 10 and a handle 20. The support body 10 has a support surface 101 on one side, which can hold samples. The handle 20 may be disposed on and connected to the support surface 101. Users can use the handle 20 to pick up and put down the support body 10.

[0035] The number of handles 20 can be designed according to actual needs. For example, such as... Figure 2 As shown, the number of handles 20 can be multiple, making it convenient for users to operate with both hands.

[0036] like Figure 4 As shown, Figure 4 for Figure 3 The exploded view of the sample holder 100 shown shows that in some embodiments, the handle 20 may include a gripping portion 21. The gripping portion 21 is disposed on the bearing surface 101, one end of the gripping portion 21 is connected to the bearing body 10, and the gripping portion 21 extends in a direction away from the bearing surface 101.

[0037] Because the gripping part 21 extends in a direction away from the bearing surface 101, the user can easily grasp the gripping part 21, thereby facilitating the handling of the bearing body 10. For example, as... Figure 4 As shown, the gripping part 21 is located above the support body 10 and extends upward toward the support body 10.

[0038] like Figure 4 As shown, the end face of the holding part 21 away from the bearing surface 101 has a mounting groove 2121. The mounting groove 2121 can be used to set an identification label 300. Thus, when using the sample holder 100 to hold a sample, the identification label 300 corresponding to the sample can be placed in the mounting groove 2121. Subsequently, the testing instrument 200 can directly identify the type of sample through the identification label 300, eliminating the need for manual identification and input, thereby improving the level of automation.

[0039] like Figure 4 As shown, the opening of the mounting groove 2121 faces away from the bearing surface 101. Generally, when the sample holder 100 is in use, the bearing surface 101 is usually facing upwards. Since the opening of the mounting groove 2121 faces away from the bearing surface 101, the testing instrument 200 can easily test the identification label 300 and identify the label.

[0040] For example, such as Figure 2As shown, the detection chamber contains a label detection unit (not shown in the figure), which can be located above and behind the entrance of the detection chamber. Thus, when the sample holder 100 is placed inside the detection chamber, the bearing surface 101 ( Figure 4 ) can be set relative to the label detection unit, mounting slot 2121 ( Figure 4 The slot of the label detection unit is also positioned opposite to the label detection unit, which can more effectively identify the identification label 300 in the mounting slot 2121.

[0041] It is understood that the specific type of the identification tag 300 is not limited in the embodiments of this application, as long as it can achieve the identification function. In some embodiments, the identification tag 300 can be a radio frequency identification (RFID) tag. In this case, the identification tag 300 can use radio signals for identification.

[0042] In some embodiments, the frequency band of the identification tag 300 can be 125kHz-135kHz. For example, the frequency band of the identification tag 300 can be 125kHz, 130kHz, or 134kHz. In this case, the lower frequency band of the identification tag 300 has better biocompatibility and can be better applied in medical scenarios. For example, when the detection instrument 200 is a cell imaging analysis system, the low-frequency characteristics of the identification tag 300 have good compatibility with cells.

[0043] Specifically, in some embodiments, the frequency of the identification tag 300 can also be 134.2 kHz. In this case, the frequency band of the identification tag 300 has better biocompatibility and can be better applied to medical scenarios.

[0044] When the detection instrument 200 is a cell imaging analysis system, if the frequency band of the identification tag 300 is too high, it may affect the electromagnetic compatibility of the detection instrument 200. Therefore, when the detection instrument 200 is a cell imaging analysis system, the identification tag 300 in the above-mentioned frequency band is selected.

[0045] It is understandable that the frequency band of the identification tag 300 can also be other values, and the frequency band of the identification tag 300 can be selected according to different application scenarios. For example, the frequency band of the identification tag 300 can also be 13.56MHz, which is a high-frequency band. Alternatively, the frequency band of the identification tag 300 can also be 860MHz-915MHz, which is an ultra-high-frequency band. For example, the frequency band of the identification tag 300 can be 860MHz, 890MHz, or 915MHz.

[0046] Of course, the identification label 300 can also be other types of identification labels 300. In some embodiments, the identification label 300 can also have a barcode or a QR code. In this case, the label detection unit 230 can directly obtain the corresponding information by scanning the identification label 300.

[0047] The specific form of the identification label 300 can also be selected according to the actual situation. For example, the identification label 300 can be a plastic-sealed label or a sticker label. At the same time, the shape of the identification label 300 can also be selected according to the actual situation. For example, the identification label 300 can be circular or square.

[0048] In some embodiments, the support body 10 can be a metal support body, that is, the support body 10 can be made of a metal material. The support body 10 can be directly made using existing materials. For example, the support body 10 can be made of a single metal material. In this case, the support body 10 has high precision and high flatness, thereby ensuring the flatness of the sample placement and facilitating subsequent detection and observation.

[0049] Of course, the supporting body 10 can also be made of non-metallic materials, and the specific choice can be made according to the actual situation.

[0050] As can be seen from the above, the identification tag 300 can be a radio frequency identification tag. When the radio frequency identification tag is placed on a metal surface, the signal will be shielded. The strong reflection of radio waves by the metal and the eddy current loss will cause the signal to attenuate or even fail to communicate.

[0051] Therefore, in some embodiments, the gripping part 21 can be a non-metallic gripping part, that is, the gripping part 21 is made of a non-metallic material. The gripping part 21 can be directly made using existing materials. For example, the gripping part 21 can be made of a single non-metallic material.

[0052] When the gripping part 21 is a non-metallic gripping part, the signal of the identification tag 300 can be avoided from being blocked due to the influence of metallic materials. The material of the gripping part 21 can be selected according to the actual situation; for example, the gripping part 21 can be made of plastic. Similarly, the gripping part 21 can also be made of metallic materials, depending on the specific circumstances.

[0053] In some embodiments, the distance between the bottom of the mounting groove 2121 and the bearing surface 101 along a direction perpendicular to the bearing surface 101 can be greater than or equal to 10 mm. For example, the distance between the bottom of the mounting groove 2121 and the bearing surface 101 can be 10 mm, 15 mm, or 20 mm, etc. Thus, when the bearing body 10 is made of metal and the gripping part 21 is made of non-metallic material, the gap between the bottom of the mounting groove 2121 and the bearing surface 101 prevents the metal material from affecting the signal of the identification tag 300 when the identification tag 300 is an RFID tag, ensuring normal identification.

[0054] In some embodiments, such as Figure 4 As shown, the handle 20 may also include a grip cover 22. The grip cover 22 may be disposed on the end of the grip portion 21 away from the bearing surface 101 and cover the opening of the mounting groove 2121. In this way, the grip cover 22 can play a protective role, preventing the identification tag 300 located in the mounting groove 2121 from falling out of the mounting groove 2121, and at the same time, it can also hide the identification tag 300.

[0055] In some other embodiments, the handle 20 may not include the grip cover 22. In this case, in order to better fix the identification tag 300 in the mounting groove 2121, a limiting structure may be provided in the mounting groove 2121 to prevent the identification tag 300 from falling out of the mounting groove 2121, thus ensuring that the identification tag 300 is fixed in the mounting groove 2121.

[0056] Alternatively, the identification label 300 can be a sticker-type label. In this way, the identification label 300 can be directly affixed into the mounting slot 2121 for fixation, without the need for other fixing structures to secure the identification label 300.

[0057] Understandably, when the handle 20 includes the holding cover 22, the tag detection unit 230 should not be affected by the holding cover 22 when detecting the identification tag 300 in the mounting slot 2121. Therefore, when the identification tag 300 is an RFID tag, the holding cover 22 can be made of a non-metallic material. This way, the holding cover 22 will not interfere with the RFID tag's signal, ensuring the RFID tag's radio transmission.

[0058] In order to secure the cover plate 22 to the end of the gripping part 21, in some embodiments, the groove wall of the mounting groove 2121 may have a first limiting portion (not shown in the figure). The peripheral wall of the cover plate 22 may have a second limiting portion (not shown in the figure). The first limiting portion and the second limiting portion may engage with each other. In this way, the cover plate 22 can be secured to the end of the gripping part 21 by engaging the first limiting portion and the second limiting portion.

[0059] It is understandable that the specific forms of the first and second limiting portions can be selected according to the actual situation. In some embodiments, the first limiting portion can be a limiting groove, and the second limiting portion can be a limiting protrusion. The limiting protrusion can be located within the limiting groove. In this way, the cover plate 22 can be fixed by the cooperation of the limiting protrusion and the limiting groove.

[0060] Of course, in some embodiments, the first limiting part can also be a limiting protrusion, and the second limiting part can be a limiting groove. Alternatively, both the first limiting part and the second limiting part can be limiting protrusions. In this case, the second limiting part can be located on the side of the first limiting part near the bottom of the mounting groove 2121. In this way, the second limiting part can remain engaged under the obstruction of the first limiting part.

[0061] In some embodiments, such as Figure 4 As shown, the gripping part 21 may include a first gripping part 211 and a second gripping part 212. One end of the first gripping part 211 is connected to the support body 10, and one end of the second gripping part 212 is connected to the other end of the first gripping part 211. The other end of the second gripping part 212 has a mounting groove 2121. The vertical projection of the first gripping part 211 onto the support surface 101 is located inside the vertical projection of the second gripping part 212 onto the support surface 101.

[0062] Thus, as Figure 4 As shown, a recessed structure can be formed between the second gripping part 212 and the supporting body 10 through the first gripping part 211. Users can use the recessed structure formed by the first gripping part 211 and the second gripping part 212 to pick up and put down the object, making it more convenient.

[0063] It is understandable that the specific shapes of the first gripping part 211 and the second gripping part 212 can be designed according to the circumstances. For example, as shown in 4, both the first gripping part 211 and the second gripping part 212 can be cylindrical structures. Of course, both the first gripping part 211 and the second gripping part 212 can also be cuboid structures.

[0064] In other embodiments, the gripping portion 21 may also be a single columnar structure, such as the gripping portion 21 may only include a second gripping portion 212 having a mounting groove 2121. The specific shape of the second gripping portion 212 can also be selected according to the actual situation. For example, the second gripping portion 212 may be a cylindrical structure.

[0065] In some embodiments, the gripping part 21 can be detachably connected to the support body 10. This facilitates the replacement of the gripping part 21. Of course, the gripping part 21 can also be integrally connected to the support body 10.

[0066] To achieve a detachable connection between the gripping part 21 and the supporting body 10, in some embodiments, such as Figure 4 As shown, the sample holder 100 may also include a first fastener 31 and a second fastener 32. One end of the first fastener 31 may be located on the side of the support body 10 away from the handle 21, and the other end may pass through the support body 10 and extend into the mounting groove 2121.

[0067] The second fastener 32 can be located within the mounting groove 2121, fitted onto the first fastener 31, and threadedly connected to the first fastener 31. In this way, the first fastener 31 and the second fastener 32 can be disassembled and installed through a threaded connection.

[0068] When the first fastener 31 and the second fastener 32 are separated from each other, the holding part 21 can be separated from the bearing body 10. For example, the first fastener 31 can be a bolt and the second fastener 32 can be a nut.

[0069] In some embodiments, such as Figure 4 As shown, the bottom of the mounting groove 2121 may have a positioning groove 2122. The second fastener 32 may be located within the positioning groove 2122. In this way, the positioning groove 2122 can provide positioning for the second fastener 32, facilitating the fixing of the second fastener 32 within the mounting groove 2121.

[0070] In some embodiments, the first fastener 31 and the second fastener 32 may also be made of non-metallic materials. In this case, the first fastener 31 and the second fastener 32 will not affect the identification tag 300.

[0071] Of course, the gripping part 21 can also be detachably connected to the support body 10 in other ways. In some embodiments, the gripping part 21 and the support body 10 can be provided with snap-fit ​​parts respectively. The gripping part 21 and the support body 10 can also be detachably connected by snap-fit ​​between the snap-fit ​​parts on the gripping part 21 and the support body 10.

[0072] Alternatively, in some embodiments, magnetic elements may be provided on both the gripping part 21 and the supporting body 10. In this case, the gripping part 21 and the supporting body 10 can be connected by mutual attraction of the magnetic elements.

[0073] like Figure 3 As shown, to facilitate the clamping assembly 40's clamping of the sample, in some embodiments, the bearing surface 101 may have a placement groove 102. Meanwhile, as... Figure 3 As shown, the sample holder 100 may also include a clamping assembly 40. One end of the clamping assembly 40 is movably connected to the bearing surface 101 and is located around the placement groove 102.

[0074] The other end of the clamping assembly 40 can be moved to a position opposite to the placement groove 102. At this time, the other end of the clamping assembly 40 can be positioned above the placement groove 102 and above the sample. Thus, the other end of the clamping assembly 40 can abut against the sample, fixing the sample within the placement groove 102.

[0075] The other end of the clamping assembly 40 can also be moved to a position offset from the placement slot 102. At this time, the clamping assembly 40 and the placement slot 102 are offset from each other, and the user can directly remove the sample from the placement slot 102.

[0076] To achieve the movable connection of the clamping assembly 40, in some embodiments, one end of the clamping assembly 40 can be rotatably connected to the support body 10, and the axis of rotation is perpendicular to the support surface 101. In this way, the other end of the clamping assembly 40 can rotate around the end of the clamping assembly 40 that is rotatably connected to the support body 10 in a plane parallel to the support surface 101, and move to a position opposite to or offset from the placement groove 102.

[0077] In other embodiments, one end of the clamping assembly 40 may be rotatably connected to the support body 10, and the axis of rotation may be parallel to the support surface 101. In this way, the other end of the clamping assembly 40 may rotate about the end of the clamping assembly 40 that is rotatably connected to the support body 10 in a plane perpendicular to the support surface 101, and move to a position opposite to or offset from the placement groove 102.

[0078] It is understood that the specific structure of the clamping component 40 can vary, as long as it can effectively clamp the sample. In some embodiments, such as Figure 4 As shown, the clamping assembly 40 may include a rotating shaft 41, a spring 42, and a limiting member 43. The rotating shaft 41 may be connected to the bearing surface 101. For example, the rotating shaft 41 may be a bolt, connected to the bearing body 10 by a threaded connection.

[0079] Spring 42 can be sleeved on rotating shaft 41. One end of limiting member 43 is sleeved on rotating shaft 41, located on the side of spring 42 away from bearing surface 101. One side of limiting member 43 abuts against spring 42, and the other side abuts against rotating shaft 41. In this way, one end of limiting member 43 can be kept in a fixed position by the abutment of rotating shaft 41 and spring 42, and the other end of limiting member 43 can rotate around rotating shaft 41, so that the other end of limiting member 43 can move to a position opposite to placement groove 102, or move to a position offset from placement groove 102.

[0080] In some embodiments, such as Figure 4As shown, the limiting member 43 can be a sheet-like structure, and the limiting member 43 can be inclined. Along the direction from the end of the limiting member 43 near the spring 42 to the end of the limiting member 43 away from the spring 42, the distance between the limiting member 43 and the bottom of the placement groove 102 gradually decreases. In this way, the limiting member 43 can act as abutment against the sample, thereby restricting the movement of the sample.

[0081] In some embodiments, such as Figure 5 As shown, Figure 5 This is a schematic diagram of another sample holder 100 provided in an embodiment of this application. The limiting member 43 can also be a block structure, and the limiting member 43 has an abutment protrusion 431. The end of the limiting member 43 away from the spring 42 and the side closer to the placement groove 102 has the abutment protrusion 431. Thus, the abutment protrusion 431 can act as abutment against the sample to limit its movement.

[0082] For example, the abutment protrusion 431 can abut against the sample from the side of the sample, while other positions of the limiting member 43 can abut against the sample from above, making the sample more securely fixed.

[0083] Understandably, the number of clamping components 40 can be designed according to actual needs. For example... Figure 5 and Figure 6 As shown, Figure 6 This is a schematic diagram of another sample holder 100 provided in an embodiment of this application. In some embodiments, there are multiple clamping components 40. In this way, multiple clamping components 40 can achieve a better clamping effect on the sample and ensure the sample is fixed.

[0084] For example, such as Figure 5 As shown, the bearing surface 101 can have a placement groove 102. Simultaneously, the number of clamping components 40 can be two, with the two clamping components 40 spaced apart on the periphery of the placement groove 102. In this case, the two clamping components 40 can clamp the sample at different positions to ensure the sample is securely fixed. Alternatively, as... Figure 6 As shown, the bearing surface 101 may have two placement slots 102. Simultaneously, the number of clamping assemblies 40 can be four. The four clamping assemblies 40 are arranged in pairs, spaced apart, on the periphery of the two placement slots 102.
