[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0023] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually relative to the directions shown in the drawings, or relative to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually relative to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0024] like Figure 1-5 As shown, the present application provides an observation device for stem cell culture, including a sealed chamber 1 and an observation component 2, the observation component 2 includes a support plate 201 arranged in the sealed chamber 1, a support column 207 is fixed on the support plate 201, a placement plate 205 is sleeved and rotatably arranged on the support column 207, a culture dish 206 is arranged on the placement plate 205, a sealed door 101 is hinged on one side of the sealed chamber 1, a movable groove 104 is provided on the inner bottom of the sealed chamber 1 and the surface of the sealed door 101, a movable bar 202 is fixedly connected to the bottom of the support plate 201, and the movable bar 202 is slidably arranged in the movable groove 104.

[0025] When the device is in use, the extracted stem cells are placed in the culture dish 206, and the sealing door 101 is passed through the first fixing block 103, so that the entire sealed chamber 1 is sealed, so that the stem cells can be cultured in a warm state, and the sealed chamber 1 is a transparent structure, so that the staff can observe the inside of the device in a sealed state;

[0026] After the sealed door 101 is opened, it will be aligned with the position of the sealed chamber 1, so that the sealed door 101 and the inner bottom of the sealed chamber 1 will be in a flat state. At this time, the entire observation component 2 can be pulled outward, so that the observation component 2 can be taken out from the inside of the sealed chamber 1, so that the staff can conveniently observe the stem cells inside the observation component 2 from the outside, thereby improving the use effect of the equipment and the observation diversity;

[0027] When the observation component 2 is moved, the second fixing block 209 can be loosened to separate the top of the support column 207 from the top of the sealed chamber 1, and then the observation component 2 can be pulled as a whole inside the sealed chamber 1, so that the observation component 2 can be taken out. During the pulling process, the third fixing block 211 will be close to the fixing hole 102, and will enter the sealing door 101 after the observation component 2 moves. When it moves to the extreme position, the third fixing block 211 and the fixing hole 102 will be combined, so that the observation component 2 will be fixed after it is taken out, thereby avoiding shaking when the observation component 2 is observed. Furthermore, when the observation component 2 moves, the two sets of moving bars 202 move at the moving groove 104, so that the smoothness of the observation component 2 can be improved when it moves.

[0028] An annular groove 203 is provided on the top of the support plate 201, and the axis of the annular groove 203 is colinear with the rotation axis of the placement plate 205. A plurality of support bars 204 are distributed along the axis of the bottom of the placement plate 205, and the support bars 204 are inserted into the annular groove 203. The placement plate 205 includes a plate body 2051, and a fixing box 2052 is fixedly connected to the top of the plate body 2051.

[0029] When the placement tray 205 is in use, the tray body 2051 contacts the top of the support base 208, so that the entire placement tray 205 can be placed. At the same time, the support column 207 allows the placement tray 205 itself to rotate, so that the four groups of culture dishes 206 can be rotated and observed at the same position of the device, thereby improving the observation efficiency. Furthermore, the culture dishes 206 allow stem cells to be stored and cultured. At the same time, when an external device observes one group of culture dishes 206, the tray body 2051 can be rotated, and one group of culture dishes 206 will be aligned with the external observation device, thereby achieving observation outside the device.

[0030] A second fixed block 209 is installed on one side of the top of the support column 207, and a plurality of moving wheels 210 are movably connected to the top of the support column 207. A third fixed block 211 is installed on the top of the support plate 201. The sealed chamber 1 is made of transparent material, the first fixed block 103 and the end of the sealed door 101 are matched with each other, the interior of the moving groove 104 and the moving bar 202 are matched with each other, and a plurality of transmission wheels are installed at the bottom of the moving bar 202.

[0031] The elastic tube 2054 is internally installed with an elastic member, and the clamping block 2053 is an arc-shaped structure. The number of the clamping blocks 2053 is four groups. By installing the clamping blocks 2053 and the elastic tube 2054, the culture dish 206 can be squeezed when it is installed inside the fixing box 2052. On the one hand, the culture dish 206 can be clamped after being placed inside the fixing box 2052, thereby ensuring the stability of the culture dish 206; on the other hand, the fixing box 2052 can be suitable for culture dishes 206 of different diameters, so as to improve the use effect of the device.

[0032] The second fixing block 209 can be in contact with the inner top of the sealed chamber 1, so that the observation component 2 can be fixed when installed inside the sealed chamber 1, wherein the second fixing block 209 and the first fixing block 103 are simultaneously installed with fixing pins, and the inner top of the sealed chamber 1 is installed through the fixing pins inside the second fixing block 209, so that the stability of the observation component 2 during installation can be improved, and at the same time, the moving wheel 210 can contact with the inner top of the sealed chamber 1, so that the smoothness of the observation component 2 when taking it out can be further improved, and when the placement plate 205 rotates on the top of the support base 208, the four groups of support bars 204 contact the position of the annular groove 203, so that the stability can be improved when the placement plate 205 is rotated and adjusted.

[0033] A plurality of transmission wheels are installed at the bottom of the movable bar 202. The sealed chamber 1 is made of transparent material, so that the internal of the device can be observed in a sealed state. At the same time, the first fixed block 103 is adapted to the end of the sealed door 101, so that the sealed door 101 can be fixedly combined with the sealed chamber 1.

The bottom of the placement tray 205 is in contact with the bottom of the support base 208 , so that the placement tray 205 can be installed on the outside of the support column 207 .

[0035] An elastic part is installed inside the elastic tube 2054, and the clamping block 2053 is an arc-shaped structure. The number of the clamping blocks 2053 is four. The elastic part is installed inside the elastic tube 2054, so that the elastic tube 2054 has elasticity, so that the clamping block 2053 can clamp the culture dish 206 through the elastic tube 2054. The clamping block 2053 is an arc-shaped structure, so that the clamping block 2053 and the culture dish 206 are more adaptable.
