Description

Technical Field

[0001] The invention belongs to the technical field of cell detection equipment, and in particular relates to a cell detection instrument. Background Art

[0002] Cell culture technology involves multiple fields, such as vaccine production, cell therapy and drug screening in the medical field, animal disease prevention and control and animal breeding in the agricultural field, etc. Among them, in the process of animal breeding research, the cultivation of germ cells such as oocytes is a basic requirement.

[0003] Taking common animal cell culture as an example, the steps of animal cell culture mainly include: 1. Sampling and tissue processing: Take out relevant tissue blocks from the animal body, cut them into pieces or digest them with trypsin into single cells to make cell suspensions. For example, oocytes are collected from ovaries, and most of the collected oocytes form cumulus oocyte complexes with cumulus cells. 2. Primary culture: Transfer the cell suspension into the culture medium and place it in a carbon dioxide incubator for culture. At this time, the cells will grow on the wall of the culture bottle. 3. Subculture: When the cells are attached to the wall of the bottle, use enzymes to disperse them into single cells and culture them again. This process can be repeated many times to form subculture. 4. Cell freezing and recovery: In order to preserve cells for a long time or conduct a large number of experiments, cells can be frozen. During freezing, add the cell suspension to the freezing solution, divide it into cryopreservation tubes, and quickly freeze it for storage. During recovery, take out the cells from the cryopreservation tubes, thaw them, and then re-culture them. In the above-mentioned animal cell culture process, detection is an important step in observing and recording the culture status of animal cells.

[0004] Among many cell detection methods, morphological detection is a relatively common detection item. By observing the cell morphological characteristics, cytoplasmic structure, etc., the cell activity and quality can be judged. Microscopes are commonly used cell morphology observation equipment. Animal cell culture is mostly adherent culture and batch operation, and batch operation is also required for observation and recording. For example, when observing cell morphology using a microscope, it is necessary to observe multiple sample pieces produced. The existing microscope includes a stage, an eyepiece and an objective lens, or includes a closed cavity with a magnifying glass and a stage. Since a stage usually holds a sample piece, the microscopic observation operation is a single observation operation, and the sample needs to be constantly replaced. Repeated operations are required to complete the observation of large quantities of samples, which is time-consuming and labor-intensive. Summary of the invention

[0025] In order to enable those skilled in the art to better understand and implement the technical solution of the present invention, the present invention is further described below in conjunction with specific embodiments and drawings.

[0026] The inventive concept of the present invention is as follows:

[0027] Since the existing microscope observation operation is a single observation operation, it is necessary to constantly change samples and repeat the operation multiple times to complete the observation of large quantities of samples, which is time-consuming and laborious.

[0028] The present invention provides a cell detector, see Figure 1 to Figure 6 , including a microscope inspection component body 1 and a sample rack 2. The microscope inspection component body 1 has the functions of recording, photographing or magnifying, which respectively correspond to recording, photographing and magnifying the cell morphology. The structure of the sample rack 2 is shown in Figure 2 , including a base 21, a chamber 22, a rotating support 23 and a guide rail 24. The base 21 is provided with a chamber 22, the top of the chamber 22 is open, and a rotating support 23 is placed in the chamber 22. The number of the rotating support 23 is an odd number greater than or equal to 5. The guide rail 24 is arranged in a serpentine shape around the rotating support 23, and the head end and the tail end of the serpentine shape are connected together to form a closed loop of the transmission track. The guide rail 24 includes a first track 241 and a second track 242. The first track 241 and the second track 242 are arranged side by side. The first track 241 and the second track 242 are connected by a plurality of support bodies 25 to form a ladder-shaped track. The support bodies 25 or between adjacent support bodies 25 are used to place cell samples. The side walls of the first track 241 and the second track 242 facing each other are both provided with a plurality of adjustment protrusions 243, and the angle between adjacent adjustment protrusions 243 is adjustable. Specifically, when there is an adjustment protrusion 243 between the first track 241 and the rotating pillar 23, the angle between the adjustment protrusions 243 on the side wall of the first track 241 at the rotating pillar 23 becomes smaller, and at this time, the angle between the adjustment protrusions 243 on the side wall of the second track 242 opposite thereto becomes larger. Conversely, when there is an adjustment protrusion 243 between the second track 242 and the rotating pillar 23, the angle between the adjustment protrusions 243 on the side wall of the second track 242 at the rotating pillar 23 becomes smaller, and the angle between the adjustment protrusions 243 on the side wall of the first track 241 opposite thereto becomes larger. At least one rotating pillar 23 is provided with a driving component for controlling its rotation. When the driving component is in a working state, it can drive the closed-loop motion of the transmission track, and as the closed-loop motion of the transmission track is performed, the angle between the adjustment protrusions 243 changes.

[0029] The present invention can place and transport multiple cell samples through the above structure, which is conducive to batch testing. The sample rack 2 of the present invention has a simple structure and can be adapted to existing testing equipment, such as a microscope, by placing it on the microscope stage. In addition, in the present invention, the guide rail 24 is arranged in a serpentine shape around the rotating support 23, and the head end and the tail end of the serpentine are connected together to form a closed loop of the transmission track, which improves the space utilization of the sample rack 2 compared with traditional linear or annular transmission components.

[0030] The more detailed structure and working principle of the present invention are described below in conjunction with specific embodiments.

[0031] Example 1

[0032] A cell detector, see Figure 1 , including a microscopic inspection component body 1 and a sample rack 2.

[0033] The main body 1 of the microscopic examination component has the functions of recording, taking pictures or magnifying, which respectively correspond to recording, taking pictures and magnifying the cell morphology.

[0034] In some exemplary schemes, the main body 1 of the microscopic inspection component is a microscope, including a stage, an eyepiece and an objective lens, and the microscope is an ordinary microscope or a fluorescence microscope. These microscopes also have a lens seat, an objective lens converter, and an illumination part. The lens seat is used to support the entire lens body so that the microscope can be placed stably; the objective lens converter can rotate freely, and there are 3 to 4 round holes on the objective lens converter, which is the part where the objective lens is installed. The converter can be rotated to replace the objective lens of different magnifications; the illumination part is used to adjust the light.

[0035] In some exemplary embodiments, the microscopic inspection assembly body 1 includes a closed cavity, which is equipped with a magnifying glass, a stage, a camera, and a lighting lamp, and the stage is located below the magnifying glass, the camera, and the lighting lamp. The outer wall of the cavity is provided with a display for displaying the real-time status of the cells, and the display, the magnifying glass, the stage, the camera, and the lighting lamp are all connected to the controller.

[0036] The structure of the sample rack 2 is shown in Figure 2 , including a base 21, a chamber 22, a rotating support 23, a guide rail 24 and a support body 25.

[0037] See also Figure 3, a chamber 22 is provided inside the base 21, and the top of the chamber 22 is open. The base 21 is load-bearing, ensuring that the entire sample rack 2 remains stable during use, and will not be displaced or unbalanced due to slight shaking or external impact, thereby providing a solid guarantee for precise cells. Considering the convenience in actual operation, the base 21 also takes into account the hand-held function. Preferably, its shape and contour are set to conform to the principle of ergonomics, so that the user's hand can naturally and comfortably hold the base 21, and the sample rack 2 can be easily transferred and adjusted. The chamber 22 is used for placing objects. Preferably, the volume of the chamber 22 accounts for more than 80% of the volume of the base 21. In addition, in the preferred scheme, the base 21 and the chamber 22 are made of transparent materials. On the one hand, because transparent materials are cheap and easy to obtain, the cost is controllable when purchasing the sample rack 2 of the present invention on a large scale, making the present invention more competitive in price. On the other hand, in daily cell testing, especially in some experimental scenarios that require extremely high operational precision, users often need to pay attention to subtle dynamics inside cells. Transparent materials facilitate observation of internal conditions and reduce visual blind spots. Without the need for additional auxiliary tools or complex cell sample disassembly and inspection, cell microdynamics can be grasped in real time, greatly improving work efficiency.

[0038] See also Figure 2 A rotating support 23 is placed in the chamber 22. The rotating support 23 is vertically arranged, and its rotating axis is also vertically arranged. Figure 4 , the number of rotating pillars 23 is an odd number greater than or equal to 5, such as 5, 7, 9 or 11. The guide rails 24 are arranged in a serpentine shape around the rotating pillars 23, and the head end and the tail end of the serpentine are connected together. The odd number of rotating pillars 23 makes the connection line between the head end and the tail end of the serpentine located on the same side of the serpentine, and finally forms a closed loop of the transmission track. At least one rotating pillar 23 is provided with a driving component for controlling its rotation. Such a layout of the positions of the rotating pillars 23 and the guide rails 24 can make full use of the space, and successfully achieve the purpose of placing more cell samples in batches within the limited accommodation space of the chamber 22. The user can prepare more cell samples to be observed at one time, which greatly shortens the time interval for replacing cell samples, and the experimental process can be efficiently promoted.

[0039] In some existing microscope usage scenarios, although the robot arm grabbing samples has brought certain automation conveniences, it also has many hidden disadvantages. For example, in the frequent actions of grabbing cell samples by the robot arm, the slightest carelessness can easily cause sample splashing, resulting in the loss of precious samples. If it is a sample such as cancer cells, it may also pollute the environment. Moreover, the frequent contact between the robot arm and different cell samples can easily introduce pollutants, causing cross-infection of different cell samples, causing the originally pure cell samples to be contaminated, affecting the accuracy of the observation results, and subsequent experimental data may also be deviated as a result. The position of the rotating support 23 and the guide rail 24 of the layout of the present invention can save the robot arm grabbing operation, avoid the risk of sample splashing, contamination and waste caused by the robot arm grabbing action, and provide a practical guarantee for ensuring the safety and cleanliness of cell samples.

[0040] In some exemplary solutions, the opening of the chamber 22 matches the outer shape of the closed loop of the conveying track, and the distance between the inner edge of the opening of the chamber and the outer edge of the closed loop of the conveying track is 1mm to 3mm. The opening of the chamber 22 is used to support and guide the conveying track.

[0041] In some exemplary embodiments, the drive component is a rotating electric machine.

[0042] Reference Figure 4 and Figure 5 The guide rail 24 includes a first rail 241 and a second rail 242, and the first rail 241 and the second rail 242 are both ropes, or both are vertically arranged flat belts. The first rail 241 and the second rail 242 are arranged side by side, and the first rail 241 and the second rail 242 are connected by a plurality of support bodies 25 to form a ladder-shaped rail, and the ladder-shaped rail is arranged vertically to the rotating support 23. Preferably, the distance between adjacent support bodies 25 is 2 cm to 6 cm, such as 2 cm, 3 cm, 4 cm, 5 cm, 6 cm. Preferably, the rope is made of non-elastic material to maintain the stability of the ladder-shaped rail and maintain the vertical relationship between the ladder-shaped rail and the rotating support 23.

[0043] In some exemplary embodiments, Figure 4The 7 rotating pillars 23 include pillar No. 1 231, pillar No. 2 232, pillar No. 3 233, pillar No. 4 234, pillar No. 5 235, pillar No. 6 236 and pillar No. 7 237. Pillar No. 1 231 corresponds to the rotating pillar 23 at the head end of the snake, pillar No. 7 237 corresponds to the rotating pillar 23 at the tail end of the snake, and the rest are rotating pillars 23 at the middle end of the snake. The first track 241 and the second track 242 are arranged in a serpentine shape between pillar No. 2 232, pillar No. 3 233, pillar No. 4 234, pillar No. 5 235, and pillar No. 6 236. During the layout process, the first track 241 and the second track 242 alternately contact with pillar No. 2 232, pillar No. 3 233, pillar No. 4 234, pillar No. 5 235, and pillar No. 6 236, and the first track 241 bypasses pillar No. 1 231 and pillar No. 7 237 to finally form a transmission track closed loop. When the driving component is in working state, it can drive the corresponding rotating support 23 to rotate, thereby driving the closed-loop motion of the conveying track.

[0044] The support 25 or between adjacent supports 25 is used to place a cell sample. Preferably, the cell sample is a prepared glass slide containing cells, a stained slide containing cells, a culture plate containing cells, or a culture dish containing cells.

[0045] In some exemplary embodiments, referring to Figure 5 The support body 25 includes a connecting rod 251 and a placing platform 252. The placing platform 252 is located above the connecting rod 251, and the connecting rod 251 and the placing platform 252 are fixedly connected. One end of the connecting rod 251 is connected to the first track 241, and the other end of the connecting rod 251 is connected to the second track 242. The placing platform 252 is used to place the cell sample.

[0046] In some exemplary embodiments, referring to Figure 6 The support body 25 includes two connecting rods 251 and a placement platform 252. The two connecting rods 251 are respectively located on both sides of the placement platform 252, and the connecting rods 251 are arranged through the placement platform 252, and the connecting rods 251 are movable at the penetration point. The portion of the connecting rod 251 located in the placement platform 252 is larger than the size of the penetration point to prevent the connecting rod 251 from falling. The two side walls of the placement platform 252 where the connecting rods 251 are not arranged are provided with grooves 253. The grooves 253 of two adjacent placement platforms 252 are opposite to each other, and can clamp cell samples. The movable connection at the penetration point helps to adjust the angle formed between the two connecting rods 251 and the placement platform 252 to match cell sample culture dishes of different shapes.

[0047] Since the first track 241 and the second track 242 contact with the No. 2 column 232, the No. 3 column 233, the No. 4 column 234, the No. 5 column 235, and the No. 6 column 236 alternately, the alternating process causes a slight change in the contact angle between the first track 241 and the rotating support 23, and a slight change in the contact angle between the second track 242 and the rotating support 23. In order to better adapt to such changes, ensure the smoothness of the cell sample transmission process, and reduce the bumping of the cell sample caused by the slight change in angle, one end of the connecting rod 251 is rotationally connected to the first track 241, and the other end is rotationally connected to the second track 242. For example, the rotation connection is achieved by a rotating shaft, a hinge, or a hinge.

[0048] In order to further ensure the smoothness of the cell sample transmission process and reduce the bumps of the cell sample caused by slight changes in angle, the side walls opposite to each other of the first track 241 and the second track 242 are provided with a plurality of adjustment protrusions 243, and the angles between adjacent adjustment protrusions 243 are adjustable. Figure 5 When there is an adjusting protrusion 243 between the second track 242 and the rotating pillar 23, the angle α between the several adjusting protrusions 243 there becomes smaller, while the angle β between the adjusting protrusions 243 on the first track 241 opposite thereto becomes larger, then the adjusting protrusion 243 on the second track 242 is tightly abutted against its corresponding rotating pillar 23, and the adjusting protrusion 243 on the first track 241 is tightly abutted against the inner edge of its corresponding chamber 22.

[0049] In some exemplary embodiments, the adjusting protrusion 243 is a triangle or a trapezoid, and the base of the triangle or the trapezoid is used to be set on the first track or the second track. The side of the rotating pillar 23 is provided with a convex tooth engaged with the adjusting protrusion 243, which is used to stably connect and transmit the first track 241 and the second track 242. The open inner edge of the chamber 22 is a smooth edge, which is conducive to increasing the angle of the adjusting protrusion 243.

[0050] In some exemplary embodiments, each support body 25 is provided with 3 to 5 adjustment protrusions 243 .

[0051] In some exemplary embodiments, the adjustment protrusion 243 is made of a rubber block that has both plasticity and elasticity to meet the needs of angle adjustment.

[0052] The present invention can place and transport multiple cell samples through the above structure, which is conducive to batch testing. The sample rack 2 of the present invention has a simple structure and can be adapted to existing testing equipment, such as a microscope, by placing it on the microscope stage. In addition, in the present invention, the guide rail 24 is arranged in a serpentine shape around the rotating support 23, and the head end and the tail end of the serpentine are connected together to form a closed loop of the transmission track, which improves the space utilization of the sample rack 2 compared with traditional linear or annular transmission components.

The side walls of the first track 241 and the second track 242 are both provided with a plurality of adjustment protrusions 243, and the angles between adjacent adjustment protrusions 243 are adjustable. The connection relationship and working principle of the above components are basically the same as those in Example 1.

[0055] Different from Example 1, in this embodiment, the rope includes a straight section and a raised section, and the raised section is formed by a plurality of adjustment protrusions 243 being movably connected in sequence. The straight section can be a plastic rope, a steel wire rope or a cotton rope. The adjustment protrusions 243 of this embodiment are rigid blocks, such as metal blocks or hard plastic blocks, and adjacent adjustment protrusions 243 are connected by flexible joints to achieve the purpose of angle change. Preferably, the flexible joint is a rubber strip bonded to the bottom edge of the adjustment protrusion 243. The bottom edge of the adjustment protrusion 243 refers to a side used to connect the first track 241 or the second track 242. If the adjustment protrusion 243 is a trapezoid, the long bottom edge of the trapezoid is used to connect the first track 241 or the second track 242.
