Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, and in particular relates to a device for treating anesthesia waste gas in operating rooms. Background Technology

[0002] Anesthesia can prevent patients from feeling pain during surgery and can also reduce fear and anxiety. When anesthetic is inhaled by the patient, some of it will be expelled through the patient's breathing, forming anesthetic waste gas. In addition, anesthetic gases may leak from equipment such as anesthesia machines and ventilators, which will also produce anesthetic waste gas.

[0003] These anesthetic exhaust gases contain harmful volatile organic compounds, halogen gases, carbon dioxide, etc. If they are directly discharged into the operating room, they will harm the health of medical staff and patients. Therefore, it is necessary to filter the anesthetic exhaust gases in the operating room to protect the health of medical staff and patients and avoid long-term health risks caused by harmful anesthetic gases.

[0004] 1. Filters are prone to clogging: Existing anesthetic exhaust gas filtration systems are generally dedicated anesthetic exhaust gas filter canisters. However, these canisters are easily affected by dust, microorganisms, and other solid particles in the operating room, causing them to clog prematurely and requiring frequent replacements, which increases unnecessary maintenance and purchase costs.

[0005] 2. Lack of disinfection and sterilization function: Traditional anesthetic exhaust gas filtration systems usually only focus on removing particulate matter and anesthetic gases from the air, while ignoring microorganisms and bacteria in the air. This results in the air in the operating room containing a large number of pathogens, increasing the risk of surgical infection.

[0006] Therefore, there is a need for an operating room anesthesia waste gas treatment device with low maintenance frequency and disinfection function to solve the above problems. Summary of the Invention

[0007] In response to the above situation and to overcome the shortcomings of the prior art, this invention provides an operating room anesthesia waste gas treatment device. Through the principles of hydraulic filtration, automatic detection and discharge, intelligent control and modular design, it achieves functions such as high-efficiency filtration and automatic discharge, enhanced disinfection and sterilization, automated operation and energy saving. It overcomes the technical biases of the prior art, such as easy clogging of the filtration system, limited disinfection effect, slow response of the control system and complex equipment maintenance and high failure rate, and provides an efficient, reliable and environmentally friendly anesthesia waste gas treatment solution.

[0049] A vent pipe 32 is fixedly installed inside the upper support plate 2. A one-way valve 33 is installed inside the vent pipe 32.

[0050] An air supply pipe 19 is fixedly installed through the lower wall of the spray tank 7. The air supply pipe 19 is connected to the spray tank 7.

[0052] The central processing unit 9 is electrically connected to the sewage pump 24.

[0053] In practical use, firstly, disinfectant is injected into the water storage tank 6, filter tank 13, and outer cylinder 15 through the exhaust port. Then, the anesthetic waste gas filter tank 5 is installed into the exhaust port. At this time, the spray water pump 21 is started. The spray water pump 21 draws the disinfectant into the transmission water pipe 22 and sprays the disinfectant into the spray tank 7 through the water mist nozzle 17. Then, the air pump 18 is started. The air pump 18 draws in the air from the operating room and transmits it to the spray tank 7 through the air supply pipe 19 and one-way valve 20.

The return water pump 23 transports the disinfectant in the spray tank 7 to the water storage tank 6 through the return pipe 31 to complete the water circulation.

[0054] During this process, when the water in the guide bucket 8 enters the filter bucket 13, the impeller 12 rotates under the action of the water flow, thereby driving the suction pipe 11, cleaning brush 14 and stirring rod 10 to rotate. The stirring rod 10 can make the gas more evenly dispersed in the disinfectant, increase the contact area between the gas and the disinfectant, and promote the separation of airborne particles from the gas more quickly.

[0055] The cleaning brush 14, when rotating, can scrub the filter holes of the filter canister 13, thereby preventing the filter holes from being completely blocked. As the filtration time increases, more and more solid impurities will accumulate in the filter canister 13. At this time, the water flow rate passing through the water flow sensor 16 in the filter canister 13 will gradually decrease. The water flow sensor 16 monitors the water flow rate in real time, obtains water flow status data, and transmits the water flow status data to the central processing unit 9. The central processing unit 9 controls the suction pump 24 to start, sucking out the impurities in the filter canister 13. Specifically, the following steps are included:

[0057] Step S2: Data preprocessing: The central processing unit 9 performs filtering, noise reduction and smoothing on the digital signal of water flow state data to obtain preprocessed water flow state data;

[0058] Step S3: Error Calculation: Set the target value for water flow, calculate the error between the target value for water flow and the pre-processed water flow state data, and obtain the error data;

[0059] Step S4: PID control: Input the error data into the PID controller, and generate a control signal according to the gain parameters in the PID controller. The gain parameters of the PID controller include proportional parameters, integral parameters and derivative parameters.

[0060] Step S5: PSO Optimization of PID Parameters: The gain parameters of the PID controller are optimized using the particle swarm optimization algorithm to obtain the optimal PID controller gain parameters. The control signal is then optimized based on the optimal PID controller gain parameters to generate the final control signal.

[0061] Step S6: Control command generation: Generate control commands for the vacuum pump 24 based on the final control signal to control the start and stop of the vacuum pump 24.

[0062] Step S5 specifically includes the following steps:

[0063] Step S51: Initialize the particle swarm: Randomly generate the initial position and velocity of each particle in the particle swarm. The position of the particle represents the gain parameter of the PID controller.

[0064] Step S52: Evaluate the fitness value of each particle using the cost function;

[0065] Step S53: Based on the fitness value, determine the global optimal position, the individual optimal position, and the current velocity of the particles; using the global optimal position, the individual optimal position, and the current velocity of the particles, update the velocity of each particle using the velocity update formula; the particle velocity update formula is as follows:

[0066] ;

[0067] in, Indicates particle index, Indicates iterative index, Indicates the first The particle in the first Speed ​​in the next iteration Indicates the first The particle in the first Speed ​​in the next iteration Indicates inertia weight, and Represents the learning factor. and Represents a random number. Indicates the first The best historical position of each particle. This represents the global optimal position of the entire particle swarm. Indicates the first The particle in the first Current position in the next iteration Representative particles In the next time step speed

[0068] Step S54: Update the position of each particle: Update the position of each particle according to the updated velocity; the particle position update formula is as follows:

[0069] ;

[0070] in, Indicates the first The particle in the first Position in the next iteration;

[0071] Step S55: Iterative optimization: Set the maximum number of iterations, iterate through steps M2 to M4 until the maximum number of iterations is reached, terminate the iteration, output the global optimal position, and obtain the optimal PID controller gain parameters;

[0072] The sewage pump 24 sucks out the sewage containing solid impurities from the filter bucket 13 through the sewage suction pipe 11, and then discharges it into the sewage bucket 4 through the sewage discharge pipe 30, thereby realizing the automatic cleaning of impurities.
