Description

Technical Field

[0001] The invention relates to the technical field of carbon dioxide monitoring, and in particular to a carbon dioxide concentration monitoring system for a cell culture box. Background Art

[0002] A cell culture incubator is a device that simulates the growth environment of cells or tissues in a living body, and requires stable temperature, carbon dioxide level, pH, and relative saturated humidity. Among them, the stability of carbon dioxide concentration is crucial to cell growth. It is not only a product of cell metabolism, but also a key factor in maintaining the stability of the pH value of the culture solution. Therefore, real-time monitoring and adjustment of the carbon dioxide concentration in the incubator to ensure that cells grow in the best environment is an important part of the cell culture process. As disclosed in Announcement No. (CN205506791U), a carbon dioxide concentration monitoring system for a cell culture incubator is disclosed, including a temperature sensor, a carbon dioxide concentration sensor, a wireless transceiver, a main controller, a data monitoring terminal, a buzzer, and a lamp bead. The temperature sensor and the carbon dioxide concentration sensor are arranged in a carbon dioxide incubator, and the signal output end of the temperature sensor and the carbon dioxide concentration sensor is connected to the signal input end of the main controller, the signal output end of the main controller is connected to the signal input end of the wireless transceiver, the wireless transceiver is wirelessly connected to the data monitoring terminal, and the signal output end of the data monitoring terminal is also electrically connected to the buzzer and the lamp bead. The system can monitor the lack of gas in the carbon dioxide incubator in real time to prevent cell culture failure caused by lack of gas.

[0003] However, the above technical solution uses a carbon dioxide concentration sensor to monitor the carbon dioxide concentration inside the incubator. When in use, the carbon dioxide concentration sensor can only be fixed in the incubator and cannot be flexibly changed in position. It is impossible to monitor at different positions in the incubator. The accuracy of concentration monitoring is not high. In addition, when in use, only a single concentration sensor can be used for monitoring. The monitoring data is relatively single, the error is large, the accuracy of the monitoring results is not high, and there are certain disadvantages in the use process.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings:

When in use, under the action of the self-resetting sealing component 6 , so as to close the incubator shell 1, place the cell culture on the placement plate 5 in the incubator shell 1, so that the inside of the incubator shell 1 is protected from environmental factors, and at the same time, the transparent packaging plate 2 is used to observe the inside of the incubator shell 1, a hollow mounting block 7 is fixedly installed on the connecting substrate 3, a vertical mounting groove is provided on the inner wall of the hollow mounting block 7, a lifting and adjusting component 8 is installed in the vertical mounting groove, a transverse extension bar 9 is installed on the lifting and adjusting component 8, a limited position slide groove is provided on the transverse extension bar 9, and a packaged propulsion drive component 10 is installed in the limited position slide groove. When in use, the package is lifted and lowered by the lifting and adjusting component 8. The height of the encapsulated propulsion drive assembly 10 is adjusted so that the encapsulated propulsion drive assembly 10 corresponds to the square connection frame 4 at different positions, and when the encapsulated propulsion drive assembly 10 is controlled to be inserted into the square connection frame 4, the encapsulated propulsion drive assembly 10 and the self-resetting sealing assembly 6 are alternately used to seal the incubator shell 1, and a reciprocating height adjustment assembly 11 is installed on the encapsulated propulsion drive assembly 10, and a lifting base plate 12 is installed on the reciprocating height adjustment assembly 11, and an L-shaped push plate 13 and a concentration meter 14 are installed on the lifting base plate 12, and the concentration meter 14 is connected to the lifting base plate through a positioning pin assembly 15. 12 is fixedly connected. As the encapsulated propulsion drive assembly 10 is gradually pushed, the concentration meter 14 can be monitored at different lateral positions in the incubator shell 1. At the same time, the reciprocating height adjustment assembly 11 is controlled to enable the concentration meter 14 to be monitored at different height positions in the incubator shell 1, thereby realizing all-round monitoring of the carbon dioxide concentration during the cell culture process. At the same time, the positioning pin assembly 15 is used to facilitate the disassembly and assembly of the concentration meter 14, so that different types of concentration meters 14 can be used to monitor the carbon dioxide concentration, which is more flexible to use and reduces the error caused by a single type of concentration meter 14.

[0030] The self-resetting sealing assembly 6 includes a limiting slide bar 601, which is fixed in the transverse mounting groove. A pressing slider 602 is slidably sleeved on the limiting slide bar 601, and the pressing slider 602 is slidably clamped in the transverse mounting groove, and the pressing slider 602 is elastically connected to the inner wall of one end of the transverse mounting groove through a pressing spring 603. An L-shaped pressing rod 604 is fixedly installed on the pressing slider 602, and a strip sealing block 605 is fixedly installed at one end of the L-shaped pressing rod 604. The strip sealing block 605 is inserted in the square connecting frame 4. When installing or adjusting, first ensure that the limiting slide bar 601 is firmly fixed in the transverse mounting groove. Then, slide the pressing slider 602 along the limiting slide bar 601 to an appropriate position, and keep it elastically connected to the inner wall of one end of the transverse mounting groove through the pressing spring 603. In this way, the pressing slider 602 can move under the action of external force and automatically reset under the action of the spring. When the square communication frame 4 needs to be sealed, the L-shaped pressing rod 604 and the strip sealing block 605 are pushed into the insertion slot of the square communication frame 4 under the action of the pressing spring 603. At this time, the strip sealing block 605 fits tightly against the inner wall of the square communication frame 4 to form an effective seal. When controlling the encapsulated propulsion drive assembly 10 to push the concentration meter 14 into the incubator housing 1, it is only necessary to overcome the elastic force of the pressing spring 603 and pull the L-shaped pressing rod 604 and the strip sealing block 605 out of the square communication frame 4 to achieve replacement sealing of the encapsulated propulsion drive assembly 10.

[0031] The lifting and adjusting assembly 8 includes a driving motor 801 and a vertical threaded rod 802. The driving motor 801 is fixed on the inner wall of one end of the vertical mounting groove. The vertical threaded rod 802 is rotatably mounted on the inner wall of the other end of the vertical mounting groove through a first rotating joint 803. One end of the vertical threaded rod 802 is fixedly connected to the output shaft of the driving motor 801. A lifting threaded slider 804 is installed on the vertical threaded rod 802. The lifting threaded slider 804 is slidably engaged in the vertical mounting groove. The horizontal extension bar 9 is fixed on the lifting threaded slider 804. The driving motor 801 is fixed on the inner wall of one end of the vertical mounting groove, and it is ensured that the vertical threaded rod 802 is firmly rotatably mounted on the inner wall of the other end of the vertical mounting groove through the first rotating joint 803. The output shaft of the driving motor 801 is fixedly connected to one end of the vertical threaded rod 802, thereby driving the rotation of the vertical threaded rod 802. On the vertical threaded rod 802, a lifting threaded slider 804 is installed. The slider can slide up and down along the rotation direction of the threaded rod and slide into the vertical mounting groove. When the height needs to be adjusted, the drive motor 801 is started to rotate the vertical threaded rod 802. Due to the effect of the thread, the lifting threaded slider 804 will rise or fall along the vertical threaded rod 802. Finally, the transverse extension block 9 is fixed on the lifting threaded slider 804. As the slider rises and falls, the transverse extension block 9 will also move up and down accordingly, thereby achieving the purpose of adjusting the height. The entire operation process is simple and efficient, and can meet various height adjustment requirements.

[0032] The encapsulated propulsion drive assembly 10 includes a servo motor 1001 and a transverse lead screw 1002. The servo motor 1001 is fixed on the inner wall of one end of the limiting slide. The transverse lead screw 1002 is rotatably mounted on the inner wall of the other end of the limiting slide through a second rotating joint 1003. One end of the transverse lead screw 1002 is fixedly connected to the output shaft of the servo motor 1001. A transverse propulsion thread block 1004 is installed on the transverse lead screw 1002. The transverse propulsion thread block 1004 is slidably engaged in the limiting slide. An L-shaped propulsion rod 1005 is fixedly installed on the transverse propulsion thread block 1004. , a vertical propulsion block 1006 is fixedly installed at one end of the L-shaped propulsion rod 1005, a convex sealing block 1007 is slidably sleeved on the L-shaped propulsion rod 1005, the vertical propulsion block 1006 and the convex sealing block 1007 are both horizontally corresponding to the square connecting frame 4, and the convex sealing block 1007 is elastically connected to the vertical propulsion block 1006 through a pulling spring 1008. When in use, the servo motor 1001 is fixed to the inner wall of one end of the limiting slide groove to ensure that the transverse lead screw 1002 rotates steadily at the other end through the second rotating joint 1003 and is connected to the output shaft of the servo motor 1001. After starting the servo motor 1001, the transverse lead screw 1002 starts to rotate, driving the transverse propulsion threaded block 1004 to slide in the limiting slide groove.

[0033] As the threaded block moves, the L-shaped propulsion rod 1005 and the vertical propulsion block 1006 thereon are propulsed synchronously. At the same time, the convex sealing block 1007 slides on the L-shaped propulsion rod 1005, and is elastically connected to the vertical propulsion block 1006 by the pulling spring 1008. When it is necessary to seal or propel the square communication frame 4, the servo motor 1001 is adjusted so that the vertical propulsion block 1006 and the convex sealing block 1007 are aligned with the corresponding positions of the square communication frame 4. Under the action of the pulling spring 1008, the convex sealing block 1007 is pressed against the square communication frame 4 to form a seal. Through the forward and reverse rotation of the servo motor 1001, the propulsion and withdrawal can be flexibly controlled to achieve precise driving and sealing.

[0034] The reciprocating height adjustment assembly 11 includes an upper drive sprocket 1101 and a lower drive sprocket 1102, both of which are rotatably mounted in a clearance groove provided on the vertical propulsion block 1006, one end of the upper drive sprocket 1101 is fixedly connected to the output shaft of the built-in motor of the vertical propulsion block 1006, and the upper drive sprocket 1101 and the lower drive sprocket 1102 are connected by a connecting chain 1103, a height adjustment block 1104 is fixedly mounted on the connecting chain 1103, and the lifting base plate 12 is fixed on the height adjustment block 1104, ensuring that the upper drive sprocket 1101 and the lower drive sprocket 1102 are firmly mounted in the clearance groove of the vertical propulsion block 1006, and the upper drive sprocket 1101 is driven by the built-in motor. When in use, the built-in motor is started to make the upper drive sprocket 1101 start to rotate, and the lower drive sprocket 1102 is driven to rotate synchronously through the connecting chain 1103. The height adjustment block 1104 fixed on the connecting chain 1103 moves up and down accordingly. Due to the continuity of the connecting chain 1103 and the rotation of the upper driving sprocket 1101 and the lower driving sprocket 1102, the height adjustment block 1104 presents a reciprocating lifting motion trajectory. The lifting substrate 12 is fixed on the height adjustment block 1104. As the height adjustment block 1104 rises and falls, the lifting substrate 12 will also move up and down accordingly. By controlling the forward and reverse rotation of the built-in motor, the height of the lifting substrate 12 can be accurately adjusted to achieve reciprocating height adjustment. The structure is compact, the operation is simple, the height can be adjusted frequently, and it is suitable for concentration detection at different heights.

When in use, first align and insert the square plug 1502 into the square socket 1501 to ensure that the concentration measuring instrument 14 is stably fixed on the lifting base plate 12. Then, slide the connecting pin rod 1504 on the U-shaped mounting seat 1503 so that one end of it is aligned with the connecting pin hole opened on the square socket 1501 and the square plug 1502. Under the action of the positioning spring 1507, the annular positioning block 1506 pushes the connecting pin rod 1504 to insert into the connecting pin hole, so as to achieve a firm connection between the square plug 1502 and the square socket 1501. When disassembly or adjustment is required, the square plug 1502 and the square socket 1501 can be easily separated by simply holding the lifting handle 1505, overcoming the elastic force of the positioning spring 1507, and pulling the connecting pin 1504 out of the connecting pin hole. The entire assembly structure is simple and practical, easy to operate, and can ensure a stable connection and quick disassembly between the concentration measuring instrument 14 and the lifting base plate 12.
