Description

Technical Field

[0001] The present invention relates to the technical field of experimental observation chambers, and particularly to an observation chamber for treating inflammatory bowel disease mouse models with mesenchymal stem cells. Background Art

[0002] Mice are commonly used animals in biomedical experiments. Due to their extremely similar characteristics to the human genome, high reproductive rate, high survival rate, and easy breeding, they are widely used in scientific experiments. When experimental mice are in the observation chamber, they may become restless, resulting in contamination of the inner wall of the observation chamber. Since the experimental mice inside the observation chamber generally cannot contact the external environment, manual cleaning of the inner wall of the observation chamber cannot be carried out in a timely manner. If not cleaned for a long time, it may affect the experimental observation, leading to misjudgment in the experimental observation. If the experimental mice scratch the observation chamber due to stress, it is easy to reduce the service efficiency of the observation chamber. At the same time, dirt is likely to remain on the scratches, which will also affect the experimental observation and judgment.

[0003] Therefore, an observation chamber for treating inflammatory bowel disease mouse models with mesenchymal stem cells is proposed. Summary of the Invention

[0040] During operation, after opening the cover plate 2, the experimental mouse is placed on the detection and control component 7. After closing the cover plate 2, the experimental mouse is observed. If the experimental mouse shows restlessness, at this time, due to the weight of the experimental mouse, the detection and control component 7 deflects, and then the control circuit is powered on. At this time, after the lifting protection component 4 is powered on, it moves upward to block the experimental mouse to prevent the experimental mouse from scratching the inner wall of the observation chamber 1. The lifting protection component 4 drives the cleaning and scraping component 5 to move upward. The cleaning and scraping component 5 flips under the action of the rotating and switching component 6. The continuous upward movement of the lifting protection component 4 can drive the cleaning and scraping component 5 to clean the inner wall of the observation chamber 1.

After the lifting protection component 4 is powered off, it retracts downward. The lifting protection component 4 drives the cleaning and scraping component 5 to move downward. The cleaning and scraping component 5 flips again under the action of the rotating and switching component 6.

[0046] Embodiment 3

[0047] Please refer to Figure 2 , Figure 3 and Figure 4 As shown, the detection control component 7 includes a fixed frame 701, a support rod 702, a second recovery groove 703, a second spring 704, a support plate 705, an electric contact rod 706 and a detection groove 707.

Fixed connection, the electric contact rod 706 is fixedly connected to the bottom of the support plate 705, the electric contact rod 706 is electrically connected to the electric hydraulic rod 403, the electric contact rod 706 can control the extension of the electric hydraulic rod 403, the bottom of the electric contact rod 706 is arranged as a telescopic structure, so that the electric contact rod 706 and the detection groove 707 are always in contact, the detection groove 707 is opened on the fixed platform 3, the bottom of the electric contact rod 706 is in contact with the detection groove 707, the detection groove 707 is electrically connected to the power supply used by the equipment, and plays a role in controlling the equipment circuit.

[0048] Overall working principle: In the initial state, the electro-hydraulic rod 403 is powered off. At this time, the electro-hydraulic rod 403 is in a contracted state. The electro-hydraulic rod 403 drives the lifting frame 404 to be in the lowest position. The lifting frame 404 drives the protective plate 406 to be inside the first recovery groove 405. The bottom ends of both sides of the lifting frame 404 are in the lowest position of the first lifting groove 401. The lifting frame 404 enables the rotating rod 502 to drive the fixed shaft 503 to be in the lowest position through the lifting block 501. At the same time, the lifting frame 404 enables the lifting block 501 to drive the lifting block 604 to be in the lowest position through the limiting block 601. The bottom of the lifting block 604 is in the lowest position of the second lifting groove 602. At this time, the rotating rod 502 drives the control rod 608 to be in the lowest position of the control groove 606 through the rotating plate 607. Through the control groove 606, the control rod 608 drives the rotating plate 607 to be in a vertically upward state. The rotating plate 607 enables the fixed shaft 503 to drive the scraping plate 504 to contact the inner wall of the observation chamber 1 through the rotating rod 502. The fixed shaft 503 enables the cleaning strip 505 to face inward. The first spring 610 is in a relaxed and contracted state. The first spring 610 enables the magnetic block 611 to be in the highest position of the second lifting groove 602. The second spring 704 is in a relaxed and extended state. The second spring 704 enables the support plate 705 to be in a horizontal state. The support plate 705 enables the electric contact rod 706 to be in a vertically downward state.

[0049] During operation, open the cover plate 2. At this time, place the experimental mouse for observing the treatment of inflammatory bowel disease with mesenchymal stem cells on the support plate 705, and then close the cover plate 2 to observe the experimental mouse. When the experimental mouse crawls normally on the support plate 705, the amplitude of its movement is small at this time, so that the shaking amplitude and speed of the support plate 705 are in a small state. If the experimental mouse shows abnormal restlessness, the swinging amplitude and speed of the support plate 705 will both increase. For example, after the support plate 705 tilts to the right, the support plate 705 compresses the second spring 704 on the right side and stretches the second spring 704 on the left side under the support of the support rod 702. At this time, after the support plate 705 tilts, it drives the lower end of the electric contact rod 706 to tilt to the left. The bottom of the electric contact rod 706 slides rapidly inside the detection groove 707. The rapid sliding on the detection groove 707 can make the electric contact rod 706 energized, thus realizing the rapid detection of the state of the experimental mouse, and being able to judge its restlessness situation in time according to the movement amplitude of the experimental mouse. The sensitivity of the device is improved through universal connection, preventing the problem of jamming during device detection.

[0050] At this time, the circuit is powered on. Since the electric contact rod 706 is electrically connected to the electro-hydraulic rod 403, the electro-hydraulic rod 403 is powered on. After the electro-hydraulic rod 403 is powered on, it drives the lifting frame 404 fixed on its top output end to move upward. The lower end of the lifting frame 404 moves upward inside the first lifting groove 401. The lifting frame 404 moves upward stably under the action of the first stabilizing rod 402, preventing the lifting frame 404 from shaking when moving upward, which may cause the device to be unable to clean effectively. Thus, the effectiveness of the device in cleaning the inner wall of the observation chamber 1 is ensured, and at the same time, the stability of the device during operation is improved. At the same time, when the lifting frame 404 moves upward, the lifting frame 404 drives the rotating rod 502 to move upward through the lifting block 501. The rotating rod 502 drives the fixed shaft 503 to move upward. The rotating rod 502 also drives the control rod 608 to move upward inside the control groove 606 through the rotating plate 607. Under the action of the shape of the control groove 606, after the control rod 608 moves to one side, the rotating rod 502 continues to move upward, causing the positions of the rotating rod 502 and the control rod 608 to be swapped. At this time, the rotating rod 502 will rotate when swapping positions with the control rod 608. The rotating rod 502 drives the fixed shaft 503 to rotate. The fixed shaft 503 drives the scraper 504 to rotate to the inside, and the fixed shaft 503 drives the cleaning strip 505 to rotate to the outside and contact the inner wall of the observation chamber 1. During the continuous upward movement of the lifting frame 404, the lifting frame 404 drives the protective plate 406 to move upward from inside the first recovery groove 405. The rising protective plate 406 can block the experimental mice, preventing the experimental mice from scratching the inner wall of the observation chamber 1 when they are restless. Thus, the problem of scratches on the observation chamber 1 affecting subsequent use can be reduced, the observation efficiency of the device can be improved, and the observation of the experimental mice can be prevented from being affected by scratches.

[0051] The lifting frame 404 continues to move upward. The lifting frame 404 drives the lifting block 501 to move upward. When the lifting block 501 drives the limit block 601 to slide to the highest position inside the limit groove 605, at this time, the bottom of the lifting frame 404 abuts against the bottom of the lifting block 604. The lifting frame 404 pushes the lifting block 604 to move upward. The bottom of the lifting block 604 moves upward inside the second lifting groove 602. The whole lifting block 604 moves upward. At this time, the fixed shaft 503 moves upward synchronously. The fixed shaft 503 drives the cleaning strip 505 to clean the inner wall of the observation chamber 1, thereby cleaning the dust on the inner wall of the observation chamber 1, preventing the dust from affecting the use of the observation chamber 1 and the observation of the experimental mice, and thus ensuring the effectiveness of the observation of the experimental mice. When the lifting block 604 moves to the highest position, at this time, because the bottom of the lifting block 604 is made of a magnetically conductive material, the bottom of the magnetic block 611 is magnetically attracted to the bottom of the lifting block 604.

[0052] When the restlessness of the experimental mouse stops, the detection control component 7 resumes its initial state at this time. After the electro-hydraulic rod 403 is powered off, it contracts. The contraction of the electro-hydraulic rod 403 drives the lifting frame 404 to move downward. The lifting frame 404 drives the protection plate 406 to be retracted into the first recovery groove 405. The lifting frame 404 drives the rotating rod 502 to move downward through the lifting block 501. The rotating rod 502 drives the fixed shaft 503 to move downward. At this time, under the action of the first spring 610 pulling the magnetic block 611, the lifting block 604 is pulled. The rotating rod 502 causes the rotating plate 607 to drive the control rod 608 to move downward inside the control groove 606. The control rod 608 offsets outward under the action of the shape of the control groove 606. The rotating rod 502 continues to move downward. The rotating rod 502 rotates under the action of the offset of the control rod 608. At this time, after the rotating rod 502 rotates, it drives the fixed shaft 503 to rotate. The fixed shaft 503 drives the scraping plate 504 to rotate and contact the inner wall of the observation chamber 1. The fixed shaft 503 drives the cleaning strip 505 to rotate towards the inside. Under the action of the continuous downward movement of the rotating rod 502, the scraping plate 504 is driven by the fixed shaft 503 to clean the dust on the inner wall of the observation chamber 1, solving the problem that the upper end of the inner wall of the observation chamber 1 cannot be cleaned, preventing the influence of dust and making it impossible to clearly see the inner wall of the observation chamber 1. At the same time, after the dust is cleaned downward, it can be collected. At the same time, the water vapor on the inner wall of the observation chamber 1 can also be scraped off to prevent the problem that the water vapor makes the inner wall of the observation chamber 1 blurred. When the lifting block 604 moves to the lowest position, at this time, the lifting block 604 drives the magnetic block 611 to contact the abutting block 609. Under the abutting action of the abutting block 609, the magnetic attraction relationship between the lifting block 604 and the magnetic block 611 is released.
