[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0033] like Figures 1-7As shown in this embodiment, an automated medical testing sample culture device and culture method are provided.
[0034] An automated medical testing sample culture device includes a culture device body 1, a sealing door 2 rotatably mounted on the front of the culture device body 1, a culture dish placement structure 3 on the culture device body 1, a culture chamber 4 formed inside the culture device body 1, a motor 5 fixedly mounted on the bottom of the culture device body 1, a rotating shaft 6 rotatably mounted inside the culture chamber 4, a reduction gearbox 7 fixedly mounted on the culture device body 1 between the motor 5 and the rotating shaft 6, and a rigid coupling connecting the reduction gearbox 7 to the motor 5 and the rotating shaft 6. Several placement trays 8 are uniformly fixedly installed on the surface. Two main clamping plates 9 are symmetrically slidably installed inside the placement trays 8. Several springs 10 are fixedly installed between the main clamping plates 9 and the placement trays 8. A vacuum pump 11 is fixedly installed at the bottom of the placement trays 8. A suction cup 12, which is fixedly connected to the output end of the vacuum pump 11, is fixedly installed at the bottom of the inner wall of the placement trays 8. A temperature control mechanism 13 is provided on one side of the culture device body 1. A humidity control mechanism 14 is provided on the back of the culture device body 1. A gas control mechanism 15 is provided at the bottom of the culture device body 1. A data acquisition mechanism 16 is provided on the culture chamber 4.
[0035] By setting up the culture structure 3 for placing culture dishes, the compatibility of placing different culture dishes can be improved. Several culture dishes are placed on the placement tray 8, and the culture dishes are initially clamped by the symmetrically arranged main clamping plate 9 and spring 10. Then, the vacuum pump 11 is started to draw a vacuum between the culture dish and the suction cup 12 to achieve vacuum adsorption of the culture dish. In this way, culture dishes of different sizes can be easily fixed by clamping and adsorption. The vacuum pump 11 is equipped with a lithium battery to provide power, eliminating the need for external power supply with wires. At the same time, the temperature control mechanism 13, humidity control mechanism 14 and gas control mechanism 15 set on the culture device body 1 can regulate the environment in the culture chamber 4. The drive motor 5 drives the rotating shaft 6 to rotate by the reduction gear in the reduction gearbox 7, so that the culture dishes on the several placement trays 8 can be evenly contacted with the culture environment. When the vacuum pump 11 is not connected by wires, it meets the use requirements and avoids the situation where the rotating shaft 6 drives the placement tray 8 to rotate, which would cause the wires to become tangled.
[0036] In this embodiment, as Figures 1-7As shown, a secondary clamping plate 17 is slidably mounted on the top of the main clamping plate 9. A limiting plate 18 is fixedly mounted on one side of the secondary clamping plate 17. The limiting plate 18 is provided with threaded bolts 19. Two threaded grooves 20 are symmetrically opened on the outer side of the main clamping plate 9. The temperature control mechanism 13 includes several heaters 21 and cooling elements 22, as well as a control and power supply unit 23. Several heaters 21 and cooling elements 22 are evenly distributed on one side of the inner wall of the culture chamber 4. The control and power supply unit 23 is fixedly installed on the outer side of the culture device body 1, and if... The heater 21 and the cooling element 22 are both connected to the control and power supply unit 23. The humidity control mechanism 14 includes an ultrasonic humidifier 24 and a dehumidifier 26. The ultrasonic humidifier 24 and the dehumidifier 26 are both fixedly installed on the back of the culture device body 1. Two first nozzles 25, which are fixedly connected to the output end of the ultrasonic humidifier 24, are symmetrically fixedly installed inside the culture chamber 4. An exhaust port 27 and an air outlet 28 are symmetrically fixedly installed inside the culture chamber 4, and both the exhaust port 27 and the air outlet 28 are fixedly connected to the dehumidifier 26.
[0037] With the arrangement of the secondary clamping plate 17, limiting plate 18, bolt 19, and threaded groove 20, a slidingly connected secondary clamping plate 17 is provided on the top of the main clamping plate 9. Pulling the secondary clamping plate 17 upward can increase the clamping range of the main clamping plate 9, so as to clamp and fix culture dishes of different heights. After adjusting the height, the secondary clamping plate 17 can be tightened by connecting the bolt 19 and the threaded groove 20. With the arrangement of heater 21, cooling element 22, and control and power supply unit 23, several heaters 21 and cooling elements 22 are evenly arrayed on one side of the inner wall of the culture chamber 4. The heaters 21 and cooling elements 22 are all connected to the control and power supply unit 23 using existing electrical connection methods. The control and power supply unit 23 includes a shared power supply module and a shared... The system comprises three core components: a control module, an independent execution branch, and an interlocking logic set by a PLC program. The heating element and the cooling element do not operate simultaneously. For example, if the temperature is below the set value, only the heating element starts; if it is above the set value, only the cooling element starts. When the temperature is stable, both elements go into sleep mode to avoid energy cancellation and improve temperature control efficiency. The system utilizes an ultrasonic humidifier 24, a first nozzle 25, a dehumidifier 26, an exhaust port 27, and an air outlet 28. After the ultrasonic humidifier 24 starts, it introduces gas into the culture chamber 4 through the first nozzle 25. When the humidity in the culture chamber 4 is high, the ultrasonic humidifier 24 is turned off, and the dehumidifier 26 is activated. The exhaust port 27 and air outlet 28 are used to exchange and dehumidify the interior of the culture chamber 4, maintaining a constant humidity level.
[0038] In this embodiment, as Figures 1-7As shown, the gas control mechanism 15 includes a gas mixer 29, a carbon dioxide storage tank 30, a filter pipe 31, a delivery pump 32, a three-way pipe 33, and a second nozzle 34. The gas mixer 29 is fixedly installed at the bottom of the culture device body 1 and located below the motor 5. The carbon dioxide storage tank 30 and the filter pipe 31 are both fixedly installed on the culture device body 1 and distributed on both sides of the gas mixer 29. The two delivery pumps 32 are both fixedly installed on the gas mixer 29 and connected to the carbon dioxide storage tank 30 and the filter pipe 31 respectively. The three-way pipe 33 is fixedly installed on the top of the gas mixer 29. The two ends of the top of the three-way pipe 33 penetrate the culture device body 1 and are located inside the culture chamber 4. The two second nozzles 34 of the part are fixedly connected. On the other side of the inner wall of the culture chamber 4, several humidity sensors 35, temperature sensors 36 and gas sensors 37 are fixedly installed from the inside to the outside. The humidity sensors 35, temperature sensors 36 and gas sensors 37 are arranged in an array. The data acquisition mechanism 16 includes two first guide rails 38 and a second guide rail 39, an electric telescopic rod 40 and an industrial camera 41. The two first guide rails 38 are symmetrically fixedly installed on the top of the inner wall of the culture chamber 4. The top of the second guide rail 39 is fixedly connected to the two first guide rails 38. The electric telescopic rod 40 is fixedly connected to the bottom of the second guide rail 39. The output end of the electric telescopic rod 40 is fixedly connected to the industrial camera 41.
[0039] With the gas control mechanism 15 in place, after the two delivery pumps 32 are started, they respectively deliver oxygen from the carbon dioxide storage tank 30 and gas filtered by the external filter tube 31 to the gas mixer 29 for mixing. After mixing, the gas is then delivered to the culture chamber 4 through the three-way pipe 33 and the second nozzle 34, so as to regulate the carbon dioxide and oxygen concentrations in the culture chamber 4 and achieve the gas ratio regulation. With the setting of humidity sensor 35, temperature sensor 36 and gas sensor 37, several humidity sensors 35, temperature sensors 36 and gas sensors 37 are evenly arrayed on the other side of the inner wall of the culture chamber 4 and symmetrically arranged in the upper and lower layers of the culture chamber 4, which can comprehensively detect the temperature, humidity and gas concentration in the culture chamber 4 to meet the requirements of temperature, humidity and gas regulation. The system utilizes a first guide rail 38, a second guide rail 39, an electric telescopic rod 40, and an industrial camera 41 to facilitate image data acquisition of the culture status of each group of culture dishes. Position sensors are installed on both first guide rails 38 of the same model. The two first guide rails 38 are then activated synchronously, and their movement is synchronized by the position sensors. This movement drives the second guide rail 39, which in turn moves the electric telescopic rod 40, adjusting the lateral and longitudinal position of the industrial camera 41 to align it with the culture dishes. The industrial camera 41 then acquires images of the culture dishes to collect culture data. For the lower culture dishes, the industrial camera 41 is activated to descend and acquire image data.
[0040] In this embodiment, as Figures 1-7 As shown, a PLC controller 42 is fixedly installed on the main body 1 of the culture device. The surface of the PLC controller 42 is provided with a touch display panel 43. Below the touch display panel 43 is a storage unit 44. The PLC controller 42 is provided with a transmission interface 45. Below the transmission interface 45 is a sealing plug 46 that is fixedly connected to the main body 1 of the culture device via a belt. A window frame 47 is fixedly installed on the sealing door 2. A viewing window 48 is fixedly installed inside the window frame 47.
[0041] Through the configuration of PLC controller 42, touch display panel 43, and storage unit 44, PLC controller 42, touch display panel 43, storage unit 44, motor 5, vacuum pump 11, control and power supply unit 23, ultrasonic humidifier 24, dehumidifier 26, gas mixer 29, delivery pump 32, humidity sensor 35, temperature sensor 36, gas sensor 37, first guide rail 38, second guide rail 39, electric telescopic rod 40, and industrial camera 41 are connected using existing electrical connection methods. The PLC control program in PLC controller 42 can control motor 5, vacuum pump 11, control and power supply unit 23, ultrasonic humidifier 24, dehumidifier 26, gas mixer 29, delivery pump 32, humidity sensor 35, temperature sensor 36, gas sensor 37, first guide rail 38, second guide rail 39, electric telescopic rod 40, and industrial camera 41. The rail 39, electric telescopic rod 40, and industrial camera 41 are intelligently controlled to achieve automatic start and stop, meeting the needs of intelligent use. At the same time, the data collected by the industrial camera 41 can be transmitted to the touch display panel 43 for display and to the storage unit 44 for storage, so that the staff can view the temperature, humidity, gas concentration, culture time, and sample status information in the culture chamber 4 in real time. Through the setting of transmission interface 45, sealing plug 46, window frame 47, and viewing window 48, the setting of transmission interface 45 is convenient for using USB or Ethernet interface to transmit data to mobile terminals or for equipment debugging. The sealing plug 46 can be inserted into the transmission interface 45 for protection when not in use. At the same time, the setting of window frame 47 and viewing window 48 allows the staff to directly observe the status of the culture dish in the culture chamber 4 through the sealing door 2.
[0042] In this embodiment, as Figures 1-7 As shown in the figure, the working process of the automated medical test sample culture device and culture method provided in this embodiment is as follows:
[0043] Step 1: Place several culture dishes in the placement tray 8 and clamp and fix them to the suction cup 12 by the main clamping plate 9 and the spring 10. Then start the vacuum pump 11 to draw a vacuum between the culture dishes and the suction cup 12 to perform vacuum adsorption on the culture dishes, so as to achieve the conditions for placing culture dishes of different sizes.
[0044] Step 2: Start the motor 5 to drive the rotating shaft 6 to rotate through the reduction gearbox 7, so that the rotating shaft 6 drives several placement plates 8 to rotate in the culture chamber 4. Then start the temperature control mechanism 13, and rely on the control and power supply unit 23 in the temperature control mechanism 13 to control the power supply of several heaters 21 and cooling plates 22, so that the heaters 21 and cooling plates 22 can control the temperature inside the culture chamber 4. Start the humidity control mechanism 14 to humidify the inside of the culture chamber 4 by relying on the ultrasonic humidifier 24 and the first nozzle 25, and dehumidify the inside of the culture chamber 4 by relying on the dehumidifier 26, the exhaust port 27 and the air outlet 28, thus controlling the humidity inside the culture chamber 4. Start the gas control mechanism 15 to mix the carbon dioxide in the carbon dioxide storage tank 30 and the external gas drawn by the filter pipe 31 by the gas mixer 29, and input it into the inside of the culture chamber 4 through the three-way pipe 33 and the second nozzle 34, thus controlling the gas inside the culture chamber 4, so that the rotating culture dishes can be evenly contacted with the culture environment.
[0045] Step 3: Start the data acquisition mechanism 16 and use the first guide rail 38 and the second guide rail 39 to drive the industrial camera 41 to move and adjust horizontally and vertically, align the position of the industrial camera 41 with the culture dish, and use the industrial camera 41 to acquire images of the culture dish to collect culture data. When acquiring data for the culture dish on the lower placement plate 8, the electric telescopic rod 40 can be driven to drive the industrial camera 41 to descend and acquire image data.
[0046] Step 4: The collected data is transmitted to the PLC controller 42. After being processed by the PLC controller 42, it is transmitted to the touch display panel 43 for the staff to view. The data is also transmitted to the storage unit 44 for storage. The staff can also use USB or Ethernet interface to transmit the data to a mobile terminal or to debug the equipment.
