A culture device for stem cell proliferation

Abstract

This utility model belongs to the field of stem cell proliferation technology, specifically relating to a culture device for stem cell proliferation. It includes a shell, with a heater installed inside. Connecting frames are connected to both sides of the heater, and a connecting plate is connected to one end of each connecting frame. A support block is connected to the top of the connecting plate, and a honeycomb plate is connected to the top of the support block. Multiple crossbars are fixedly connected to the inner wall of the shell, and culture dishes are mounted on the tops of the crossbars. This utility model uses a lever to move a movable block, causing a limiting pin to retract. At this time, a dustproof plate covers the surface of the heat dissipation vent. Two fixing blocks are then positioned at both ends of the mounting base. Releasing the lever causes the limiting pin to pop out under the action of a spring, and the popped-out end of the limiting pin inserts into a limiting groove on the outer wall of the fixing block. This allows for convenient installation and fixing of the dustproof plate to the surface of the heat dissipation vent, improving the tightness of the contact surface between the two.

Description

Technical Field

[0001] This invention belongs to the field of stem cell proliferation and culture technology, specifically relating to a culture device for stem cell proliferation. Background Technology

[0002] Stem cells are a type of pluripotent cell with the ability to self-replicate. Under certain conditions, they can differentiate into various functional cells. Based on their developmental stage, stem cells are divided into embryonic stem cells and adult stem cells. Based on their developmental potential, stem cells are divided into three categories: totipotent stem cells, pluripotent stem cells, and unipotent stem cells. Stem cells are undifferentiated and immature cells with the potential to regenerate various tissues, organs, and the human body. They are known in the medical field as universal cells. However, stem cell proliferation requires a culture device.

[0003] Currently, existing stem cell proliferation culture devices typically use heaters and honeycomb plates to uniformly heat the stem cells in the culture dish inside the device. However, the heaters inside the stem cell proliferation culture device generate a lot of heat during operation, so heat dissipation vents need to be opened on both sides of the device shell to dissipate heat. However, because the opening of heat dissipation vents will connect the inside of the device to the outside, impurities in the outside air will enter the device after long-term use, thus affecting the normal use and lifespan of the device. Utility Model Content

[0004] The purpose of this invention is to provide a culture device for stem cell proliferation, aiming to solve the problem that existing culture devices for stem cell proliferation typically use heaters and honeycomb plates to uniformly heat the stem cells in the culture dish. However, the heaters in the stem cell proliferation culture device generate a large amount of heat during operation, so heat dissipation vents need to be opened on both sides of the device shell to dissipate heat. However, because the opening of heat dissipation vents connects the inside of the device to the outside, impurities in the outside air will enter the device after long-term use, thereby affecting the normal use and service life of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a culture device for stem cell proliferation, comprising a shell, a heater installed inside the shell, connecting frames connected to both sides of the heater, a connecting plate connected to one end of the connecting frame, a support block connected to the top of the connecting plate, and a honeycomb plate connected to the top of the support block;

[0006] Multiple crossbars are fixedly connected to the inner wall of the outer shell, and a petri dish is provided on the top of the multiple crossbars. Heat dissipation vents are provided on both sides of the outer shell, and dustproof plates are installed on the surface of the heat dissipation vents. Two fixing blocks are fixedly connected to each side of the dustproof plates, and limit slots are provided on the outer walls of the two fixing blocks. Mounting seats are fixedly connected to the outer walls of both sides of the outer shell, and springs are provided inside the mounting seats. A movable block is connected to the end of the spring, and a limit pin is connected to one end of the movable block.

[0007] As a preferred embodiment of the culture device for stem cell proliferation according to this utility model, two dustproof plates are provided, and the two dustproof plates are symmetrically distributed on both sides of the outer shell.

[0008] As a preferred embodiment of the culture device for stem cell proliferation according to this utility model, the end of the limiting pin away from the movable block is adapted to the size of the limiting slot.

[0009] As a preferred embodiment of the culture device for stem cell proliferation according to this utility model, the two fixing blocks are symmetrically distributed at both ends of the mounting base.

[0010] As a preferred embodiment of the culture device for stem cell proliferation according to this utility model, the dustproof plate can form an elastic locking structure with the outer shell through a fixed block, a limiting slot, a mounting base, a spring, a movable block, and a limiting pin.

[0011] As a preferred embodiment of the culture device for stem cell proliferation according to this utility model, the outer walls on both sides of the outer shell are provided with sealing grooves, and the surface of the dustproof plate is fixedly connected with sealing protrusions.

[0012] As a preferred embodiment of the culture device for stem cell proliferation according to this utility model, the dimensions of the sealing protrusion and the sealing groove are adapted to each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By moving the movable block with the lever, the limiting pin retracts, covering the surface of the heat dissipation vent with the dust cover. At this time, the two fixed blocks will be located at both ends of the mounting base. Then, by releasing the lever, the limiting pin will pop out under the action of the spring, and the popped end of the limiting pin will insert into the limiting slot on the outer wall of the fixed block. This allows the dust cover to be easily installed and fixed on the surface of the heat dissipation vent, improving the tightness of the contact surface between the two.

[0015] By using sealing grooves and sealing protrusions, when the dustproof plate is installed on the surface of the heat dissipation vent, the contact area between the dustproof plate and the outer shell is increased by embedding the sealing protrusions into the sealing grooves opened on the outer wall of the outer shell. This further improves the sealing effect of the contact surface between the dustproof plate and the outer shell, preventing impurities from entering the gap between them. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: a culture device for stem cell proliferation, comprising a shell 1, a heater 2 installed inside the shell 1, connecting frames 3 connected to both sides of the heater 2, a connecting plate 4 connected to one end of the connecting frame 3, a support block 5 connected to the top of the connecting plate 4, and a honeycomb plate 6 connected to the top of the support block 5.

[0025] Multiple crossbars 7 are fixedly connected to the inner wall of the outer shell 1. A petri dish 8 is set on the top of the multiple crossbars 7. Heat dissipation vents 9 are opened on both sides of the outer shell 1. A dustproof plate 10 is installed on the surface of the heat dissipation vent 9. Two fixing blocks 11 are fixedly connected to both sides of the dustproof plate 10. Limiting slots 12 are opened on the outer walls of the two fixing blocks 11. Mounting bases 13 are fixedly connected to the outer walls of both sides of the outer shell 1. A spring 14 is set inside the mounting base 13. A movable block 15 is connected to the end of the spring 14. A limiting pin 16 is connected to one end of the movable block 15.

[0026] It should be noted that a control panel is installed on the surface of the outer casing 1 for precise control of the operation of the heater 2.

[0027] Preferably, there are two dustproof plates 10, and the two dustproof plates 10 are symmetrically distributed on both sides of the outer shell 1. The end of the limiting pin 16 away from the movable block 15 is adapted to the size of the limiting slot 12. The two fixing blocks 11 are symmetrically distributed at both ends of the mounting base 13.

[0028] In practical use, the movable block 15 is moved by the lever to retract the limiting pin 16, which covers the surface of the heat dissipation vent 9 with the dust cover 10. At this time, the two fixing blocks 11 will be located at both ends of the mounting base 13. Then, by releasing the lever, the limiting pin 16 will pop out under the action of the spring 14, and the popped end of the limiting pin 16 will be inserted into the limiting slot 12 on the outer wall of the fixing block 11. This allows the dust cover 10 to be easily installed and fixed on the surface of the heat dissipation vent 9, improving the tightness of the contact surface between the two.

[0029] Preferably, the dustproof plate 10 can form an elastic engagement structure with the outer shell 1 through the fixing block 11, the limiting slot 12, the mounting base 13, the spring 14, the movable block 15, and the limiting pin 16.

[0030] In practical use, the movable block 15 is moved by the lever to cause the limit pin 16 to retract. At this time, one end of the limit pin 16 will disengage from the limit groove 12 on the outer wall of the fixed block 11. Then, the dustproof plate 10 is pulled outward to disengage the sealing protrusion 18 from the sealing groove 17, so that it can be easily disassembled.

[0031] Preferably, sealing grooves 17 are provided on both outer walls of the outer casing 1, and sealing protrusions 18 are fixedly connected to the surface of the dustproof plate 10, with the dimensions of the sealing protrusions 18 and the sealing grooves 17 being compatible.

[0032] In practical use, with the setting of sealing groove 17 and sealing protrusion 18, when the dustproof plate 10 is installed on the surface of heat dissipation port 9, by embedding the sealing protrusion 18 into the sealing groove 17 opened on the outer wall of the outer shell 1, the contact area between the dustproof plate 10 and the outer shell 1 will increase, thereby further improving the sealing effect of the contact surface between the dustproof plate 10 and the outer shell 1 and preventing impurities from entering the gap between them.

[0033] Working principle: First, by moving the movable block 15 with the lever, the limiting pin 16 retracts, covering the surface of the heat dissipation vent 9 with the dust cover 10. At this time, the two fixing blocks 11 are located at both ends of the mounting base 13. Then, by releasing the lever, the limiting pin 16 will pop out under the action of the spring 14, and the popped end of the limiting pin 16 will insert into the limiting groove 12 on the outer wall of the fixing block 11. This allows the dust cover 10 to be easily installed and fixed on the surface of the heat dissipation vent 9, improving the tightness of the contact surface between the two. Furthermore, through the sealing groove 17, the sealing... With the protrusion 18 installed, when the dustproof plate 10 is installed on the surface of the heat dissipation vent 9, the contact area between the dustproof plate 10 and the outer shell 1 will increase by embedding the sealing protrusion 18 into the sealing groove 17 opened on the outer wall of the outer shell 1. This will further improve the sealing effect of the contact surface between the dustproof plate 10 and the outer shell 1, and prevent impurities from entering the gap between them. At this time, the stem cells are placed in the culture dish 8, the culture dish 8 is placed on multiple crossbars 7 and the top cover is closed. Then, the heat dissipation vent 9 is controlled by the control panel on the outer shell 1 to uniformly heat the inside of the device for stem cell reproduction.
