Description

Technical Field

[0001] This invention relates to the field of cell culture technology, and more specifically to a user-friendly human cell culture device. Background Technology

[0002] Human cell culture refers to the implantation of normal cells cultured in vitro, cells with introduced exogenous genes, or specific cells derived from stem cells through induced differentiation into the diseased area of ​​a patient to compensate for the function lost by the diseased cells. Human cell culture can also be used to assist in drug research and development, and this technology is widely used in biology and medicine. However, a culture apparatus is required to assist in human cell culture.

[0003] For example, Chinese patent number 201822091222.5 provides a human stem cell culture device that has a revitalizing effect on damaged cells. In use, the placement plate is pulled out using the cooperation of a placement plate and a first slider, allowing for the placement and removal of culture dishes on the plate. Analysis of the aforementioned patent and existing technology reveals that traditional cell culture devices are easily limited by their own structure when placing and removing culture dishes, making it inconvenient to place and remove multiple dishes. This necessitates repeatedly pulling out each placement plate, and the culture dishes are prone to collisions with the culture device during placement and removal, leading to damage. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention proposes a convenient human cell culture device to solve the technical problems mentioned in the background art, that is, when placing and taking out culture dishes, the traditional cell culture device is easily limited by the structure of the cell culture device itself, which makes it inconvenient to place and take out multiple culture dishes, requiring repeated pulling out of each placement plate, and the culture dishes are prone to collision with the culture device during the placement and taking out process, resulting in damage to the culture dishes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a user-friendly human cell culture device, comprising a shell and a hinged shielding door.

A support plate is provided inside the outer shell, and two sets of second positioning frames are provided on the support plate. The two sets of second positioning frames are arranged opposite to each other, and the two sets of second positioning blocks are slidably engaged within the two sets of second positioning frames respectively.

[0009] In a preferred embodiment, the propulsion mechanism includes a scissor lift, a first mounting rod is provided at the bottom of the housing, a second mounting rod is provided at the bottom of the support frame, a first sliding cylinder is provided at one end of the scissor lift via a first hinge seat, and a second sliding cylinder is provided at the other end of the scissor lift via a second hinge seat. The two sets of first sliding cylinders are slidably sleeved on the two ends of the first mounting rod, and the two sets of second sliding cylinders are slidably sleeved on the two ends of the second mounting rod.

[0010] In a preferred embodiment, the propulsion mechanism further includes two sets of transmission rods. Support shafts and support rods are provided on both sides of the inner wall of the outer casing. The middle section of each transmission rod is rotatably connected to the support shaft. Sliding frames are provided at both ends of each transmission rod. First control posts are provided at the bottom of the two sets of first hinge seats. Third sliding cylinders are slidably fitted onto both sets of support rods. Second control posts are provided on the third sliding cylinders. The first and second control posts are slidably engaged within the sliding frames. A third hinge seat is provided on one side of the third sliding cylinder, and a fourth hinge seat is provided on the inner side of the shielding door. The third and fourth hinge seats are connected by a connecting rod.

[0011] In a preferred embodiment, the shielding door is provided with a cavity for the movement of the support frame.

[0012] In a preferred embodiment, the support frame is provided with two sets of support frames, the culture dish is placed inside the support frames, and the bottom of the support frames has a through hole.

[0013] In a preferred embodiment, each set of the support brackets is provided with a clamping mechanism for stably fixing the culture dish. The clamping mechanism includes two sets of L-shaped rods. A connecting frame is provided at the bottom of the support bracket. Mounting shafts are provided on both sides of the connecting frame and on both sides of the inner wall of the support bracket. The corner of the L-shaped rod is rotatably sleeved on the mounting shaft. One end of the L-shaped rod is movably disposed in a through groove opened on the support bracket. A sector gear is provided at the other end of the L-shaped rod. The two sets of sector gears mesh with each other. The center of the sector gear coincides with the axis of the mounting shaft. A clamping arc plate is provided on the L-shaped rod. One set of clamping arc plates is provided with an opening block. A return spring is provided on one side of each set of L-shaped rods. One end of each set of return springs contacts the connecting frame and the support bracket, respectively.

[0014] In a preferred embodiment, a push block is provided at one end of the sector gear. The push block is made of rubber and contacts the bottom of the culture dish. A fastening block is provided at the bottom of the clamping arc plate. The fastening block is made of rubber and contacts the top of the culture dish.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In use, this human cell culture apparatus places culture dishes on the support racks to culture human cells. When it is necessary to remove or place the culture dishes, two sets of shielding doors can be opened. During the opening process, the bottom set of support racks is moved out of the outer shell by a pushing mechanism. The movement trajectory and range of the support racks are monitored by a positioning component. During the movement of the bottom set of support racks, the upper set slides simultaneously through the cooperation of guide columns and the first guide rail, thus exposing a large area of ​​the upper surface of the lower set of support racks and preventing the upper set from being exposed. The support brackets obstruct the culture dishes, and similarly, the movement of the other three types of support brackets is controlled so that the five sets of support brackets are arranged in a trapezoidal shape. This effectively avoids collisions between the culture dishes and the culture vessel during the process of picking up and placing the culture dishes. At the same time, there is no need to control the repeated movement of multiple placement plates in the existing culture vessel, which makes it convenient to pick up and place the culture dishes on each support bracket. Furthermore, the clamping mechanism stably fixes the culture dishes after placement, preventing damage to the culture dishes when they are moved or when the culture vessel as a whole is impacted. In addition, this culture vessel is easy to use and improves the efficiency of human cell culture.

[0017] 2. During the opening of the two sets of shielding doors, the third sliding cylinder is controlled to slide on the support rod via a connecting rod. This, in turn, allows the transmission rod to rotate along the support shaft via the cooperation of two sets of second control columns and two sets of sliding frames. During rotation, the transmission rod, through the cooperation of the other two sets of sliding frames and the first control column, controls the two sets of first sliding cylinders to slide and close on the first mounting rod, thereby controlling the movement of the scissor lift to advance the lowest set of support frames. This structural design allows the support frames to be stably arranged in a trapezoidal shape, facilitating the placement and removal of culture dishes.

[0018] 3. This human cell culture apparatus uses a return spring and clamping arc plates to stably fix the culture dish, preventing damage from collisions between the culture dish and the support frame when the apparatus is impacted. When placing or removing a culture dish from the support, a single finger can be used to turn the opening block, causing one set of L-shaped rods in the clamping mechanism to rotate along the mounting axis. This, in turn, is controlled by two sets of sector gears to simultaneously rotate the other set of L-shaped rods along the mounting axis, opening both sets of clamping arc plates. During this movement, the sector gears control the upward movement of the push block above them, pushing the culture dish upwards a certain distance, making removal of the culture dish easier and quickly and stably fixing the placed culture dish, thus improving the convenience of using this human cell culture apparatus.

Detailed Implementation

[0029] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0030] Example:

[0031] like Figures 1 to 5 As shown, this invention provides a user-friendly human cell culture device, comprising a shell 101 and two sets of hinged shielding doors 109. Five sets of support frames 401 are disposed inside the shell 101, arranged in a stacked manner. A pushing mechanism is provided at the bottom inner side of the shell 101, connecting to the two sets of shielding doors 109 and one set of support frames 401. The support frames 401 in this culture device support a culture dish 601 for culturing human cells. The internal temperature of the culture device is controlled by temperature control devices 103 located on both sides of the inner wall of the shell 101, ensuring the cultured cells are in a constant-temperature environment. During the opening of the two sets of shielding doors 109, the bottom support frame 401 can be moved out of the shell 101 by the pushing mechanism.

[0032] The propulsion mechanism includes a scissor lift 201, a first mounting rod 104 at the bottom of the housing 101, a second mounting rod 405 at the bottom of the support frame 401, a first slide cylinder 203 mounted via a first hinge seat 202 at one end of the scissor lift 201, and a second slide cylinder 204 mounted via a second hinge seat 205 at the other end of the scissor lift 201. The two sets of first slide cylinders 203 are slidably sleeved on both ends of the first mounting rod 104, and the two sets of second slide cylinders 204 are slidably sleeved on both ends of the second mounting rod 405.

[0033] The propulsion mechanism also includes two sets of transmission rods 301. Support shafts 105 and support rods 106 are provided on both sides of the inner wall of the outer casing 101. The middle section of the transmission rod 301 is rotatably connected to the support shaft 105. Slide frames 302 are provided at both ends of the transmission rod 301. First control posts 206 are provided at the bottom of the two sets of first hinge seats 202. Third slide cylinders 304 are slidably sleeved on the two sets of support rods 106. Second control posts 303 are provided on the third slide cylinders 304. The first control posts 206 and the second control posts 303 are slidably locked in the slide frames 302. A third hinge seat 305 is provided on one side of the third slide cylinder 304. A fourth hinge seat 110 is provided on the inner side of the shielding door 109. The third hinge seat 305 and the fourth hinge seat 110 are connected by a connecting rod 306.

[0034] During the opening of the two sets of shielding doors 109, the fourth hinge seat 110 is moved. During the movement of the fourth hinge seat 110, the third hinge seat 305 can be moved through the connecting rod 306, so that the two sets of third slide cylinders 304 slide on the two sets of support rods 106 respectively. During the sliding process, the two sets of third slide cylinders 304 control the two sets of transmission rods 301 to rotate along the support shaft 105 through the cooperation of the two sets of second control columns 303 and the two sets of slide frames 302 respectively. During the rotation of the transmission rods 301, the first slide cylinder 203 is controlled to slide on the first mounting rod 104 through the cooperation of the slide frame 302 at its other end and the first control column 206. The two sets of first slide cylinders 203 on the first mounting rod 104 close together to control the movement of the scissor lift 201.

[0035] During the movement, the scissor lift 201 extends, causing the two sets of second slide cylinders 204 to move in opposite directions on the second mounting rod 405 to close, thereby controlling the lowermost set of support brackets 401 to move out.

[0036] like Figure 6 , 7 As shown, in this embodiment, each support frame 401 is provided with two sets of culture dishes 601 installed by a clamping mechanism. The clamping mechanism is used to stably fix the culture dishes 601. The support frame 401 is provided with two sets of support frames 409. The culture dishes 601 are placed in the support frames 409. The bottom of the support frames 409 has a through hole.

[0037] The clamping mechanism includes two sets of L-shaped rods 503. A connecting frame 501 is provided at the bottom of the support frame 401. Mounting shafts 502 are provided on both sides of the connecting frame 501 and both sides of the inner wall of the support frame 401. The corner of the L-shaped rod 503 is rotatably sleeved on the mounting shaft 502. One end of the L-shaped rod 503 is movably set in a through groove 510 opened on the support frame 401. The other end of the L-shaped rod 503 is provided with a sector gear 504. Two sets of sector gears 504 mesh with each other. The center of the sector gear 504 coincides with the axis of the mounting shaft 502. A clamping arc plate 507 is provided on the L-shaped rod 503. One set of clamping arc plates 507 is provided with an opening block 509. A return spring 506 is provided on one side of both sets of L-shaped rods 503. One end of the two sets of return springs 506 contacts the connecting frame 501 and the support frame 401 respectively.

[0038] The clamping mechanism stably fixes the culture dish 601 by cooperating with the return spring 506 and the clamping arc plate 507, preventing the culture dish 601 from colliding with the support frame 409 and being damaged when the culture vessel is impacted. When picking up or placing the culture dish 601 on the support frame 401, the opening block 509 is turned by a single finger, which drives one set of L-shaped rods 503 in the clamping mechanism to rotate along the mounting shaft 502. Then, through the cooperation of two sets of sector gears 504, the other set of L-shaped rods 503 are controlled to rotate simultaneously along the mounting shaft 502, thereby controlling the two sets of clamping arc plates 507 to open, so that the culture dish 601 can be picked up or placed.

[0039] A push block 505, made of rubber, is provided at one end of the sector gear 504. The push block 505 contacts the bottom of the culture dish 601. A fastening block 508, also made of rubber, is provided at the bottom of the clamping arc plate 507. The fastening block 508 contacts the top of the culture dish 601. During its movement, the sector gear 504 controls the push block 505 above it to move obliquely upwards, pushing the culture dish 601 upwards a certain distance, making it easier to remove the culture dish 601 and improving the convenience of using this human cell culture apparatus.

[0040] like Figure 1 , 5 As shown in Figure 6, in this embodiment, guide posts 403 are provided on both sides of the support frame 401, and first guide rails 402 are provided on both sides of the four sets of support frames 401. Two sets of second guide rails 108 are provided on the top inner side of the outer shell 101. Eight sets of guide posts 403 are slidably locked in the eight sets of first guide rails 402, and the other two sets of guide posts 403 are slidably locked in the two sets of second guide rails 108.

[0041] During movement, the bottom set of support brackets 401 controls the sliding of the upper set of support brackets 401 simultaneously through the cooperation of the guide column 403 and the first guide rail 402. This exposes a large area of ​​the upper surface of the lower set of support brackets 401, preventing the upper support brackets 401 from obstructing the culture dish 601. Similarly, the movement of the other three sets of support brackets 401 is controlled, so that the five sets of support brackets 401 are arranged in a trapezoidal shape. This effectively avoids collisions between the culture dish 601 and the culture vessel during the process of picking up and placing the culture dish 601. At the same time, there is no need to control the repeated movement of multiple placement plates in the existing culture vessel. This culture vessel is more convenient to use and improves the efficiency of human cell culture.

[0042] like Figure 2 , 5As shown in Figure 6, in this embodiment, one set of support brackets 401 is connected to the outer shell 101 through a positioning assembly. The positioning assembly includes a first positioning frame 407, and positioning rods 404 are provided on both sides of the support bracket 401. A first positioning block 406 is provided at one end of the positioning rod 404. The two sets of first positioning blocks 406 are slidably engaged in the two sets of first positioning frames 407. A second positioning block 408 is provided at one end of each set of first positioning frames 407. A support plate 102 is provided inside the outer shell 101. Two sets of second positioning frames 107 are provided on the support plate 102. The two sets of second positioning frames 107 are arranged opposite to each other. The two sets of second positioning blocks 408 are slidably engaged in the two sets of second positioning frames 107 respectively.

[0043] During the movement of the lowest set of support frames 401, the first positioning blocks 406 at one end of the positioning rods 404 on both sides slide within the two sets of first positioning frames 407 respectively until the first positioning blocks 406 slide to the limit position at one end of the first positioning frame 407, driving the first positioning frame 407 to move. The second positioning block 408 at one end of the first positioning frame 407 slides within the second positioning frame 107. Through the cooperation of the positioning rods 404, the first positioning frame 407 and the second positioning frame 107, the movement of the lowest set of support frames 401 is stably positioned and limited, which improves the stability of the internal structure of the incubator. At the same time, it can provide stable support for the upper sets of support frames 401.

[0044] like Figure 1 As shown, in this embodiment, a cavity is provided inside the shielding door 109 for the movement of the support frame 401. The cavity provides sufficient space for the movement of the lowermost support frame 401, preventing it from contacting the two shielding doors 109 during movement due to its large travel distance, thus avoiding interference with the movement of the support frame 401. Similarly, closing the two shielding doors 109 allows multiple support frames 401 to be simultaneously retracted into the outer casing 101 without occupying a large space.

[0045] Specific usage and beneficial effects of the present invention:

[0046] The human cell culture device can culture human cells through culture dish 601. When it is necessary to take out or put in the culture dish 601 inside the culture device, two sets of shielding doors 109 can be opened at the same time. During the movement of the shielding doors 109, the connecting rod 306 controls the two sets of third sliding cylinders 304 to slide on the two sets of support rods 106 respectively. During its movement, the third slide cylinder 304 controls the two sets of second slide cylinders 204 to move from the outside to the inside at both ends of the second mounting rod 405 through the cooperation of the first control column 206, the second control column 303, and the four sets of transmission rods 301. During the movement, the two sets of second slide cylinders 204 can control the extension of the scissor lift 201, pushing the lowest set of support brackets 401 out. As the lowest set of support brackets 401 moves out of the outer shell 101, the guide column 403 can slide within the first guide rail 402 or the second guide rail 108, thereby pulling the other four sets of support brackets 401 out. This results in the multiple support brackets 401 being arranged in a trapezoidal shape, which facilitates the placement and removal of the culture dishes 601 on each support bracket 401. Furthermore, the culture dishes 601 are less likely to collide with the culture vessel during the placement and removal process, making human cell culture work more convenient.

[0047] The return spring 506 keeps the two sets of L-shaped rods 503 in a closed state, which, together with the clamping arc plate 507 and the fastening block 508, fixes the culture dish 601, effectively preventing the culture dish 601 from colliding with the support frame 409 and being damaged when the culture device is moved, thus improving the practical value of the culture device. When it is necessary to pick up or put down the culture dish 601, simply move the opening block 509 to drive one set of L-shaped rods 503 to rotate along the mounting shaft 502, and control the rotation of the other set of L-shaped rods 503 through the cooperation of the two sets of sector gears 504, so that the two sets of clamping arc plates 507 open at the same time, and push the culture dish 601 upward a certain distance through the push block 505 on the sector gear 504, making it easier to pick up and put down the culture dish 601, and enabling convenient and quick stable fixation of the placed culture dish 601.

[0048] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
