Description

Technical Field

[0001] This utility model relates to the field of cell culture, and in particular to an in vitro culture device for lung cancer tissue. Background Technology

[0002] Lung cancer tissue is a malignant tumor originating from the epithelium of the bronchi, bronchioles, or alveoli. In vitro culture equipment provides a controllable experimental platform for lung cancer research by simulating the human microenvironment. By using patient tumor cells to construct "surrogates," the genetic heterogeneity and microenvironment interaction of tumors can be replicated. In vitro models reduce the need for animal experiments, shorten the research and development cycle, and reduce the cost of new drug development.

[0003] In the prior art, patent application document "CN218115463U" discloses an "in vitro culture device for lung cancer tissue"; including a culture dish, a base at the lower end of the culture dish, a support and clamping structure at the lower end of the base, and a positioning structure at the upper end of the base; a cap, which is placed on the outer side of the upper end of the culture dish and positioned by the positioning structure, and a sealing structure at the upper end of the cap, with a handle fixedly connected to the middle of the upper end of the cap. The beneficial effects are: this utility model can increase the sealing effect of the cap by setting the sealing structure and the fastening structure, and can fasten the cap after it is put on, so as to avoid the cap shaking and gaps affecting the sealing effect. It also has a detachable support and clamping structure, which can clamp and fasten the cell culture membrane to the bottom of the culture dish, preventing the cell culture membrane from wrinkling during the experimental operation and affecting the culture effect. Moreover, it can facilitate the disassembly and replacement of the cell culture membrane, increasing the convenience of use.

[0004] The aforementioned “in vitro culture device for lung cancer tissue” still has some drawbacks. For example, existing in vitro cell culture devices need to be placed horizontally during use. If the device is tilted during placement, liquid will accumulate on one side, causing cells to be exposed to air or have excessive or insufficient nutrients, affecting proliferation and activity. Furthermore, after completing the in vitro culture experiment on lung cancer tissue, the chamber needs to be manually disinfected, which may introduce the risk of bacteria.

[0005] To address these issues, an in vitro culture device for lung cancer tissue is proposed here. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model include:

[0015] 1. Utilizing the threaded connection between the threaded column and the threaded hole, the rotation of the threaded column will drive the support block to move vertically up and down along the inner side of the side lifting frame.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] According to one embodiment of the present invention, in conjunction with Figures 1 to 6The diagram shows an in vitro culture device for lung cancer tissue, including an incubator 1. An observation window 2 is fixedly connected to one side of the incubator 1. A bottom support frame 301 is fixedly connected to the bottom of the incubator 1.

Support blocks 306 are provided on both sides of the bottom support frame 301. Threaded holes 307 are provided on the surface of the support blocks 306.

[0030] It should be noted that by utilizing the threaded connection between the threaded post 305 and the threaded hole 307, the rotation of the threaded post 305 will drive the support block 306 to move vertically up and down along the inner side of the side lifting frame 302.

[0031] In this embodiment, side slide rails 309 are provided on both sides of the side lifting frame 302, and a sliding block 308 is fixedly connected to one side of the support block 306. The surface of the sliding block 308 is slidably connected to one side of the side slide rail 309.

[0032] It should be noted that when the support block 306 moves vertically, it will cause the sliding block 308 to slide along the inner side of the side slide rail 309, which improves the stability of the support block 306 when it moves vertically.

[0033] In this embodiment, an inner connecting frame 401 is provided on the inner side of the bottom support frame 301, and a side connecting groove 403 is provided on the other side of the bottom support frame 301.

A top connecting hole 4011 is provided on the top of the incubator 1. A heat sink 408 is fixedly connected to one side of the top water tank 407.

[0034] It should be noted that the disinfectant in the top water tank 407 is drawn out along the side spray pipe 4010 by the top water pump 409. By opening the top connecting hole 4011, one end of the side spray pipe 4010 is fixed inside the incubator 1. At this time, the disinfectant flowing out of the side spray pipe 4010 is sprayed out in an atomized form by the atomizing nozzle 4012. The heat dissipation fin 408 on one side of the top water tank 407 increases the heat dissipation area, reduces the temperature of the disinfectant in the top water tank 407, and improves the stability of the disinfectant.

[0035] In this embodiment, an inner fixing plate 501 is fixedly connected to the inner side of the top water tank 407, a top bearing plate 502 is movably connected to one side of the inner fixing plate 501, a transmission plate 503 is movably connected to one side of the top bearing plate 502, a transmission rod 504 is fixedly connected to one side of the transmission plate 503, and an agitator 505 is fixedly connected to one end of the transmission rod 504.

[0036] It should be noted that the rotating transmission plate 503 will drive the transmission rod 504 to rotate, and the rotating transmission rod 504 will drive the agitator 505 to agitate, thereby agitating the disinfectant in the top water tank 407 and improving the activity of the disinfectant.

[0037] In this embodiment, the top of the incubator 1 is provided with a top protective cylinder 601, the inner side of the top protective cylinder 601 is fixedly connected with a top mounting hole 602, the top of the top mounting hole 602 is fixedly connected with a top fixing bracket 603, one side of the top fixing bracket 603 is fixedly connected with a motor body 604, the output shaft of the motor body 604 is fixedly connected with a connecting rod 605, and one end of the connecting rod 605 is fixedly connected with a transmission fan 606.

[0038] It should be noted that the rotating connecting rod 605 will drive the transmission fan 606 to rotate along the inner side of the top mounting hole 602, and extract the gas in the incubator 1, accelerate the evaporation of the disinfectant in the incubator 1, reduce residue, and improve the disinfection effect in the incubator 1.

[0039] In this embodiment, a metal side plate 609 is fixedly connected to the top of the top mounting hole 602. A side mounting hole 6011 is provided on one side of the metal side plate 609. A rubber ring 6010 is fixedly connected to the top of the metal side plate 609. A sealing plate 6012 is provided on one side of the metal side plate 609. A friction block 6013 is fixedly connected to the top of the sealing plate 6012. A magnetic suction plate 6014 is fixedly connected to one side of the sealing plate 6012. An arc-shaped groove 6015 is provided on one side of the sealing plate 6012 and one side of the metal side plate 609.

[0040] It should be noted that after the metal side plate 609 and the sealing plate 6012 are installed, the two arc-shaped grooves 6015 will fit with the connecting rod 605, and the rubber ring 6010 on the top of the metal side plate 609 will seal the arc-shaped grooves 6015, which will improve the sealing degree of the top mounting hole 602 after the sealing plate 6012 and the metal side plate 609 are installed. Furthermore, the magnetic attraction between the side mounting hole 6011 and the magnetic plate 6014 will improve the stability of the connection between the sealing plate 6012 and the metal side plate 609.

[0041] In this embodiment, a side bearing disk 607 is movably connected to one side of the transmission fan 606, and a bottom fixing frame 608 is movably connected to one side of the side bearing disk 607. The two sides of the bottom fixing frame 608 are fixedly connected to the inner side of the top mounting hole 602.

[0042] It should be noted that when the drive fan 606 rotates, it is movably supported on one side of the bottom fixed frame 608 via the side bearing plate 607, which improves the stability of the rotation of the drive fan 606.

[0043] The specific usage and function of this embodiment: The operator rotates the four gripping discs 304 according to the level of the placement surface. The rotation of the four gripping discs 304 drives the threaded column 305 to rotate. The bottom bearing disc 303 is used to movably connect the gripping discs 304 to the bottom of the incubator 1, maintaining the stability of the gripping discs 304 and the threaded column 305 during rotation. The threaded connection between the threaded column 305 and the threaded hole 307 causes the support block 306 to move vertically up and down along the inner side of the side lifting frame 302 when the threaded column 305 rotates. When the support block 306 moves vertically, it causes the sliding block 308 to slide along the inner side of the side slide rail 309, improving the stability of the support block 306 during vertical movement. By adjusting the height of the four support blocks 306 respectively, the tilt of the incubator 1 can be adjusted to maintain the levelness of the incubator 1 on different tilted placement surfaces, reducing the impact of tilt on cell activity.

[0044] Meanwhile, by fixing the storage tank 402 inside the inner connecting frame 401 and adding disinfectant through the inlet pipe 404, the disinfectant will flow into the storage tank 402 along the inlet pipe 404. When disinfecting the incubator 1 after the culture experiment is completed, the bottom water pump 405 is started to pump the disinfectant in the storage tank 402 into the top water tank 407 along the outlet pipe 406. The top water pump 409 is started to pump the disinfectant in the top water tank 407 out along the side spray pipe 4010. By opening the top connecting hole 4011, one end of the side spray pipe 4010 is fixed inside the incubator 1. At this time, the disinfectant flowing out of the side spray pipe 4010 is sprayed out in an atomized form through the atomizing nozzle 4012 to disinfect the incubator 1. This reduces the workload of the operators and eliminates the need to open the incubator 1, reducing the possibility of introducing external pollutants during manual disinfection.

[0045] Simultaneously, when the disinfectant enters the top water tank 407 along the outlet pipe 406, it impacts the transmission plate 503. The fan-shaped transmission plate 503 with an inclined angle rotates along the top bearing plate 502 after being impacted by the liquid. The transmission plate 503 is connected to the inner fixed plate 501 to maintain the free and stable rotation of the transmission plate 503 in the top water tank 407. The rotating transmission plate 503 drives the transmission rod 504 to rotate, and the rotating transmission rod 504 drives the agitator 505 to agitate the disinfectant in the top water tank 407, thereby increasing the activity of the disinfectant, reducing sedimentation, and improving the disinfection effect when the disinfectant is sprayed out along the atomizing nozzle 4012.

[0046] After disinfection, pressing the friction block 6013 pushes the sealing plate 6012. The magnetic plate 6014 is magnetically connected to the side mounting hole 6011. Applying external force causes the magnetic plate 6014 to separate along the inner side of the side mounting hole 6011. After separation, the sealing plate 6012 separates along one side of the metal side plate 609. After removing the sealing plate 6012 along the top of the top mounting hole 602, the motor body 604 is started. The motor body 604 drives the connecting rod 605 to rotate. The rotating connecting rod 605 drives the transmission fan 606 to rotate along the inner side of the top mounting hole 602, extracting the gas in the incubator 1, accelerating the evaporation of the disinfectant in the incubator 1, and reducing residue. To improve the disinfection effect inside the incubator 1, after the operation is completed, stop the rotation of the drive fan 606 and install the sealing plate 6012 and the metal side plate 609. Both the sealing plate 6012 and the metal side plate 609 have arc-shaped grooves 6015 on one side. After the metal side plate 609 and the sealing plate 6012 are installed, the two arc-shaped grooves 6015 will fit with the connecting rod 605, and the rubber ring 6010 on the top of the metal side plate 609 will seal the arc-shaped grooves 6015, which improves the sealing degree of the top mounting hole 602 after the sealing plate 6012 and the metal side plate 609 are installed. In addition, the magnetic attraction between the side mounting hole 6011 and the magnetic plate 6014 improves the stability of the connection between the sealing plate 6012 and the metal side plate 609.

[0048] The technical scope of this utility model is not limited to the content described above.
