Description

Technical Field

[0001] The present application relates to the technical field of incubator equipment, and in particular to an incubator gas consumption measurement system. Background Art

[0002] Incubators control gas concentrations to provide optimal environmental conditions, maintaining healthy and normal cell growth. This is crucial for successful cell culture and accurate experimental results. To maintain controlled gas concentrations, incubators continuously consume externally supplied gas. Monitoring incubator gas consumption levels facilitates timely refilling and identifies operational anomalies, crucial for proper operation.

[0003] Common methods for measuring incubator gas consumption are: 1. Formula method: Calculate based on parameters such as gas supply pressure, air pipe aperture, ventilation time, etc. to obtain the gas consumption over a period of time. This method is only suitable for estimation and has large errors. 2. Airflow meter monitoring: A special airflow meter is installed on the incubator gas supply line. The airflow meter is an instrument that can measure the volume flow of gas. By connecting the airflow meter to the equipment, the gas consumption of the equipment can be measured more accurately. The steps for measuring using an airflow meter are as follows: connect the airflow meter to the gas supply pipe; turn on the equipment to allow gas to flow out of the equipment; start the airflow meter and record the speed and time of the gas passing through the airflow meter over a period of time; use the data and time displayed by the airflow meter to calculate the gas consumption of the equipment. 3. Weighing method: Measure the weight difference of the gas cylinder before and after the incubator is used for a period of time, and convert it into the corresponding gas consumption.

[0004] However, the final calculated result of the formula method has a large deviation. When the airflow conduction time is extremely short and the conduction frequency is extremely high, the airflow meter cannot accurately measure the speed and time of the airflow, and therefore cannot accurately measure the gas consumption. The weighing method is inconvenient to operate, and because the gas weight is light and changes slowly, a longer ventilation time is required to obtain an accurate measurement value. Utility Model Content

[0030] See Figure 1 The incubator gas consumption measurement system of the embodiment of the present application includes: a gas supply cylinder 100, a gas supply pipe 200, a flow measuring device 400, a gas circuit switch controller 600, a time detection device 500 and a gas supply to the culture device. The gas cylinder is connected to the culture device through the gas supply pipe 200. The gas circuit switch controller 600 is on the gas supply pipe 200 and controls the start and stop of the gas supply cylinder 100. The flow measuring device 400 is set on the gas supply pipe 200 and measures the gas flow rate through the gas supply pipe 200. The time detection device 500 is set on the gas circuit switch controller 600 and records the start and stop signals of the gas circuit switch controller 600.

[0031] In this embodiment, the gas consumption measurement system comprises a flow measurement device 400 and a time detection device 500. The flow measurement device 400 is connected to the gas supply pipe 200 and is capable of monitoring and displaying the gas flow rate in the passage. The processor 520 of the on-time detection device 500 is connected to the controller of the gas supply pipe 200 and is capable of monitoring the controller's on-time and displaying the cumulative on-time. The gas consumption of the incubator 320 during this period is calculated based on the gas flow rate measured by the flow measurement device 400 and the cumulative on-time measured by the on-time detection device 500.

[0032] Specifically, the flow measurement device 400 uses a gas flow sensor to collect the gas flow rate in the gas supply pipe 200. When the controller of the incubator 320 is turned on, the gas flows from the gas supply cylinder 100 along the gas supply pipe 200 through the flow measurement device 400 and flows into the incubator 320 body of the incubator. The gas flow sensor can measure the gas flow rate in the gas supply pipe 200 in real time and output it for display. The gas flow sensor is directly installed on the gas supply pipe 200, which does not affect the circulation of the gas and does not cause gas leakage. The opening time measurement device uses a detection device to be connected to the gas circuit switch controller 600 of the incubator 320 for detecting the signal value of the gas circuit switch controller 600. When the gas circuit switch controller 600 is turned on, its signal value changes and is detected by the detection device, thereby judging that the gas circuit switch controller 600 is in the open state and can It can record the opening time until the gas circuit switch controller 600 is closed, and its signal value changes again. The detection device detects that the gas circuit switch controller 600 is in the closed state, stops timing, and obtains the opening time of the gas circuit switch controller 600 this time. The display of the opening time measuring device can display the measured opening time of the gas circuit switch controller 600 in real time. After the gas circuit switch controller 600 is turned on next time, the detection device detects the opening time again and adds it to the previous opening time. A period of measurement is set and performed. The display of the opening time measuring device displays the total time the controller is turned on during this period. After the measurement is completed, the processor 520 will issue a prompt sound to indicate the end of the measurement. According to the total opening time of the gas circuit switch controller 600 and the gas flow rate in the gas supply pipe 200, the gas consumption during this period is calculated.

[0033] In this embodiment, the opening time measuring device and the detection device are connected to the gas circuit switch controller 600 of the incubator 320 to measure its signal value, have a millisecond-level reaction speed, and can convert its signal value into a suitable input signal to transmit to the processor 520. The processor 520 calculates the time of each opening of the gas circuit switch controller 600, and according to the set time, accumulates the total time of the opening of the gas circuit switch controller 600 during this period and displays it. The connection and use of the flow measuring device 400, that is, the flow sensor is connected to the gas supply pipe 200, does not affect the circulation of the gas, will not cause gas leakage, and can display the gas flow rate in real time.

[0034] In a specific embodiment, the flow measurement device 400 is installed between the gas supply cylinder 100 and the gas circuit switch controller 600, which can prevent the gas flow rate from being affected by the gas circuit switch controller 600 and more accurately measure the passing gas flow rate.

[0035] In a specific embodiment, the time detection device 500 includes: a processor 520, which is in communication with the gas circuit switch controller 600 and records the start and stop signals of the gas circuit switch controller 600. When the gas circuit switch controller 600 is turned on, its signal value changes and is detected by the detection device, thereby judging that the gas circuit switch controller 600 is in the on state, and can continue to record the on time until the gas circuit switch controller 600 is turned off, and its signal value changes again. The detection device detects that the gas circuit switch controller 600 is in the off state, stops timing, and obtains the time when the gas circuit switch controller 600 is turned on this time.

[0036] In a specific embodiment, the time detection device 500 further includes: a display screen 510, which is in communication with the processor 520 and displays the start and stop signals of the gas circuit switch controller 600 in real time, so as to facilitate real-time observation of the start and stop of the gas circuit switch controller 600.

[0037] In a specific embodiment, the culture device includes: a shell 310 and an incubator 320 body. The shell 310 is a sealed hollow structure, and the side wall of the shell 310 is provided with air holes. The incubator 320 body is arranged inside the shell 310, and the air holes are matched with the air supply pipe 200. The air supply pipe 200 passes through the air holes and is connected to the incubator 320 body.

[0038] In this embodiment, the gas circuit switch controller 600 is located inside the housing 310 and can be protected.

[0039] The embodiments of the present application have been described above. The above description is illustrative and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
