[0071] The preferred embodiments of the present application will be described below with the help of the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to explain and illustrate the present application, and do not constitute a limitation on the present application.

[0072] The embodiment of the present application provides a gas circuit system of external counterpulsation, which comprises:

[0073] The gas circuit supervision unit is used for monitoring the running condition of the gas circuit system in real time, and performing corresponding control and adjustment on the running of the gas circuit system.

[0074] A gas pump with an air inlet hole and an air outlet hole, for sucking in gas through the air inlet hole, processing the gas, and discharging the processed gas to a gas tank through the air outlet hole;

[0075] A radiator between the gas pump and the gas tank, for cooling the gas discharged by the gas pump;

[0076] A gas tank connected to the air outlet hole of the gas pump, for storing the gas cooled by the radiator;

[0077] An electromagnetic valve arranged between the gas tank and the air bag, for controlling the flow of gas from the gas tank to the air bag, wherein the opening and closing of the electromagnetic valve are adjusted by the gas circuit supervision unit according to the needs of external counterpulsation;

[0078] An air bag for applying external pressure to the patient during external counterpulsation, the inflation and deflation of the air bag being controlled by the connected electromagnetic valve to match the treatment needs of the patient.

[0079] The working principle of the above technical solution is that the gas circuit supervision unit is a real-time monitoring system for monitoring the running state of the gas circuit system, which collects data of various components of the gas circuit system, such as the working state and gas flow of the gas pump, radiator, gas tank, etc. According to these data, the supervision unit can perform corresponding control and adjustment to ensure the normal operation of the gas circuit system; the gas pump is one of the key components of the gas circuit system, which sucks in gas through the air inlet hole, processes it, and then discharges it through the air outlet hole. The gas pump compresses or processes the sucked-in gas, and then sends the processed gas to the gas tank for storage.

[0080] The radiator is located between the gas pump and the gas tank, and its main function is to cool the gas discharged from the gas pump. This is because during the operation of the gas pump, a certain amount of heat is generated. In order to prevent the gas from overheating and affecting the normal operation of the gas circuit system, the radiator is needed to cool the gas. The gas tank is connected to the air outlet hole of the gas pump, and is used to store the gas cooled by the radiator. The gas tank acts like a buffer, which can smoothly supply the gas required by the air bag to ensure the continuity and stability of the external counterpulsation treatment. The electromagnetic valve is arranged between the gas tank and the air bag, and is mainly used to control the flow of gas from the gas tank to the air bag. During the external counterpulsation treatment, the electromagnetic valve will open or close according to the needs of the patient to adjust the flow of gas, so as to apply external pressure. The air bag is a component used to apply external pressure during external counterpulsation treatment, and its inflation and deflation are controlled by the connected electromagnetic valve. By controlling the inflation and deflation of the air bag, effective auxiliary treatment of the patient's cardiovascular system can be achieved, and the patient's blood circulation and heart function can be improved.

[0081] The beneficial effects of the above technical solution are: the gas path supervision unit can monitor the running state of the gas path system in real time, timely discover and handle abnormal situations, ensure the stable operation of the system, and improve the safety and effectiveness of treatment; the gas pump, radiator and gas tank form a complete gas treatment and storage system, which can effectively store the inhaled gas after treatment, and provide continuous gas supply for external counterpulsation treatment; the electromagnetic valve precisely controls the gas flow, which can adjust the inflation and deflation of the air bag in real time according to the treatment needs of the patient, provide appropriate external pressure, and achieve effective auxiliary treatment of the cardiovascular system; through the synergistic effect of the above components, the external counterpulsation system can more accurately treat the patient, improve the treatment effect, relieve the symptoms of cardiovascular system related diseases, and improve the quality of life of the patient.

[0082] In another embodiment, the gas path supervision unit comprises: a monitoring module, a gas pump control module and an electromagnetic valve control module;

[0083] The monitoring module is used to monitor the working state of the whole gas path system in real time, including the running state of the gas pump, the gas pressure in the gas tank, the cooling efficiency of the radiator, and the inflation and deflation state of the air bag;

[0084] The gas pump control module is used to control and adjust the working mode of the gas pump, including controlling the start, stop, air intake and exhaust volume adjustment of the gas pump;

[0085] The electromagnetic valve control module is used to control the opening and closing of the electromagnetic valve to control the gas flow between the gas tank and the air bag, and to ensure that the operation of the electromagnetic valve is synchronized with the gas demand in the external counterpulsation treatment process by receiving data and corresponding instructions from the monitoring module.

[0086] The working principle of the above technical solution is: the monitoring module is the intelligent brain of the gas path system, which monitors the working state of each key component in real time through sensors; it can monitor the running state of the gas pump, the gas pressure in the gas tank, the cooling efficiency of the radiator, and the inflation and deflation state of the air bag; when the monitoring module detects any abnormal situation, it will send corresponding instructions to the gas pump control module and the electromagnetic valve control module to trigger necessary adjustment and control operation.

[0087] The gas pump control module is responsible for managing the working mode of the gas pump, which controls the start, stop, air intake and exhaust volume adjustment of the gas pump according to the data transmitted by the monitoring module; when the monitoring module detects that the gas pressure in the gas tank is insufficient, the gas pump control module will instruct the gas pump to increase the exhaust volume to keep the gas pressure in the gas tank within a safe range.

[0088] The solenoid valve control module is the key control part of the gas circuit system, responsible for regulating the flow of gas between the gas tank and the airbag. By receiving data and instructions from the monitoring module, the solenoid valve control module can accurately open or close the solenoid valve. For example, during an external counterpulsation therapy, if the monitoring module detects that the patient needs more external pressure, the solenoid valve control module will open the solenoid valve, allowing gas to flow to the airbag, exerting more pressure.

[0089] The beneficial effects of the above technical solutions are: the real-time monitoring capability of the monitoring module enables the gas circuit system to quickly respond to any abnormal situation, ensuring stable operation of the system and minimizing the risk during patient treatment; the gas pump control module intelligently adjusts the working mode of the gas pump based on monitoring data, ensuring that the gas supply always meets the patient's treatment needs, improving the effectiveness and safety of treatment; the precise control capability of the solenoid valve control module ensures that the flow of gas between the gas tank and the airbag always matches the patient's physiological state, maximizing the effectiveness of external counterpulsation therapy; the automated gas circuit system can reduce the operational burden of medical personnel, allowing them to focus more on overall patient care and improve the efficiency of medical services; the synergistic effect of the modules ensures the continuity and stability of external counterpulsation therapy, providing more durable and reliable treatment for patients.

[0090] In another embodiment, the gas pump includes: a filter screen, an air pipe, a gas compression module, and a noise elimination module;

[0091] The filter screen is located at the air inlet hole to remove impurities before the gas enters the gas pump, ensuring the quality of the gas entering the gas pump, thereby protecting the internal mechanical components and maintaining the cleanliness of the gas;

[0092] The air pipe is used for the gas to pass through the filter screen and enter the interior of the gas pump;

[0093] The gas compression module is used for the gas inside the gas pump to be compressed by electronic compression technology, wherein the compression ratio is adjusted according to the instructions of the gas pump control module to meet the demand for gas flow and pressure in different treatment stages;

[0094] The noise elimination module is used for eliminating the noise generated during the compression of the gas, creating a quiet and comfortable treatment environment for the patient.

[0095] The working principle of the above technical solution is that the filter screen is located at the air inlet hole of the gas circuit system, which removes impurities in the gas to ensure the purity of the gas entering the gas pump; the filter screen can block particulate matter and pollutants in the air, protecting the internal mechanical components of the gas pump from damage and maintaining the cleanliness of the gas.

[0096] The trachea is a pipeline connecting the filter screen and the air pump, responsible for introducing clean gas treated by the filter screen into the air pump. It provides a channel for the smooth entry of gas into the air pump, providing a basis for subsequent gas compression and treatment.

[0097] The gas compression module uses electronic compression technology to compress the gas. According to the instructions of the air pump control module, the compression ratio can be adjusted to meet the needs of different treatment stages for gas flow and pressure. When external pressure needs to be increased, the air pump control module can adjust the working parameters of the gas compression module to increase the pressure of the output gas.

[0098] The noise elimination module is located inside the air pump. Its main task is to eliminate the noise generated during the gas compression process. This can be achieved by using soundproof materials, vibration reduction techniques or other noise reduction methods. The presence of the noise elimination module helps to create a quiet and comfortable treatment environment for patients, improving the overall treatment experience.

[0099] The beneficial effects of the above technical solutions are: the use of the filter screen can effectively remove impurities in the gas, protect the internal mechanical components of the air pump from contamination, ensure the cleanliness of the gas, and improve the stability and reliability of the gas path system; the gas compression module can adjust the compression ratio according to the needs of the treatment stage through electronic compression technology, achieving precise control of gas flow and pressure, ensuring personalized treatment for patients; the application of the noise elimination module helps to reduce the noise level during treatment, creating a quiet and comfortable environment for patients, improving the comfort of treatment; by ensuring the cleanliness of the gas, precisely controlling the gas treatment and reducing the noise level, the design of the entire gas path system helps to improve the treatment experience of patients, making them more pleasant and at ease; the role of the filter screen and the precise adjustment of the gas compression module, as well as the application of the noise elimination module, collectively enhance the stability of the gas path system, ensuring the reliability and consistency of the system during long-term treatment.

[0100] In another embodiment, the heat sink includes: a multi-layer heat exchange structure, a temperature monitoring module and an automatic cleaning device;

[0101] The heat sink uses heat exchange materials to quickly absorb and dissipate heat from the gas, ensuring that the gas reaches the corresponding temperature level before entering the gas tank;

[0102] Through the multi-layer heat exchange structure, the contact area between the gas and the heat sink is increased, improving the cooling efficiency;

[0103] The temperature monitoring module monitors the temperature changes of the gas in real time, and cooperates with the gas path control unit to ensure that the gas temperature is controlled within the preset range to adapt to different treatment needs and environmental conditions;

[0104] The automatic cleaning device is used to clean the radiator, so that the performance stability and reliability in long-term use are ensured.

[0105] The working principle of the technical solution is that the radiator uses heat exchange material. The principle is that the heat exchange material quickly absorbs and releases the heat in the gas. When the gas passes through the radiator, the heat exchange material absorbs the heat in the gas, so that the temperature of the gas decreases. In this way, the gas can reach the corresponding temperature level before entering the gas tank, providing suitable gas conditions for subsequent treatment.

[0106] To improve the cooling efficiency, the radiator adopts a multi-layer heat exchange structure, which means that the gas can pass through multiple layers of heat exchange surfaces when it comes into contact with the radiator, increasing the contact area between the gas and the radiator. By increasing the contact area, the radiator can more effectively absorb and release heat, improving the efficiency of the entire cooling process.

[0107] The temperature monitoring module monitors the temperature change of the gas in real time. The monitored temperature data is used in cooperation with the gas path control unit to ensure that the temperature of the gas is controlled within the preset range. When the temperature of the gas deviates from the preset range, the gas path control unit can adjust the working mode of the heat exchange material to keep the gas at the appropriate temperature level.

[0108] To ensure the performance stability and reliability in long-term use, the radiator is equipped with an automatic cleaning device, which can be an automatic cleaning brush, gas flushing or other mechanical cleaning means. The automatic cleaning device periodically cleans the radiator to prevent accumulated dirt from affecting the cooling effect, thereby ensuring the performance of the system in long-term operation.

[0109] The beneficial effects of the above technical solution are: the cooperation of the temperature monitoring module and the gas path control unit ensures the precise control of the temperature of the gas, adapts to different treatment needs and environmental conditions, and improves the safety and comfort of the treatment; the use of heat exchange material and multi-layer heat exchange structure increases the surface area of the gas in contact with the radiator, improves the cooling efficiency, and ensures that the gas can be effectively cooled before entering the gas tank; the use of the automatic cleaning device prolongs the service life of the radiator, maintains the performance stability and reliability in long-term use, reduces the need for maintenance and cleaning, and improves the reliability of the system; by ensuring the appropriate temperature of the gas, efficient cooling and stable system performance, the entire radiator system helps to improve the experience of patients during treatment, creating a more comfortable treatment environment for them; the radiator can reduce energy consumption while cooling, improving the energy saving of the system and meeting the environmental protection concept.

[0110] In another embodiment, the opening and closing of the electromagnetic valve are adjusted by the gas path supervision unit according to the needs of external counterpulsation, including:

[0111] The operation of the electromagnetic valve is controlled by an electromagnetic valve control module, which automatically adjusts the opening and closing state of the electromagnetic valve through programmed instructions according to the needs of extracorporeal counterpulsation therapy, realizing the management of gas flow;

[0112] The electromagnetic valve has real-time data exchange capability with the electromagnetic valve control module, and automatically adjusts the opening and closing state according to the real-time pressure changes of the gas tank and the air bag, to maintain the continuity and stability of gas flow during treatment.

[0113] The working principle of the above technical solution is that the operation of the electromagnetic valve is automatically adjusted by the electromagnetic valve control module through programmed instructions; when the extracorporeal counterpulsation therapy needs to increase external pressure, the electromagnetic valve control module will send corresponding instructions to open the electromagnetic valve and allow gas to flow to the air bag, thereby exerting stronger pressure.

[0114] The electromagnetic valve has real-time data exchange capability with the electromagnetic valve control module, and can automatically adjust the opening and closing state according to the real-time pressure changes of the gas tank and the air bag; when the pressure in the gas tank decreases, the electromagnetic valve control module will receive relevant data and adjust the state of the electromagnetic valve accordingly, ensuring that gas can continue to flow to the air bag and maintaining the continuity and stability of gas flow during treatment.

[0115] The beneficial effects of the above technical solution are: the electromagnetic valve control module automatically adjusts the opening and closing state of the electromagnetic valve through programmed instructions, realizing intelligent management of gas flow and improving efficiency and accuracy during treatment; the electromagnetic valve has real-time data exchange capability, automatically adjusts the opening and closing state according to the real-time pressure changes of the gas tank and the air bag, ensuring the continuity and stability of gas flow and providing more durable and reliable treatment effect for patients; through real-time data exchange and intelligent control, the electromagnetic valve can quickly and accurately respond to changes in the needs of extracorporeal counterpulsation therapy, providing personalized gas flow management and enhancing the effectiveness and safety of treatment; automated gas flow management reduces the operational burden of medical staff, allowing them to focus more on the overall care of patients and improving the efficiency of medical services; intelligent control and real-time adjustment of the electromagnetic valve control module help to enhance the stability of the entire gas path system, ensuring the reliability and consistency of the system during long-term treatment.

[0116] In another embodiment, the working state of the entire gas path system is monitored in real time, including:

[0117] Real-time data is collected from the gas path system, including the running state of the gas pump, the gas pressure in the gas tank, the cooling efficiency of the radiator, and the inflation and deflation state of the air bag;

[0118] The real-time data is set on a preset monitoring time axis;

[0119] Based on the monitoring cluster condition, the monitoring cluster is divided on the time axis;

[0120] State characterization of the monitoring cluster based on the preset state characterization template, obtaining a cluster state feature set;

[0121] Match the cluster state feature set with the standard state feature set in the preset standard state feature set library;

[0122] When the match is consistent, obtain the preset abnormal state confirmation strategy corresponding to the matching standard state feature set;

[0123] Based on the abnormal state confirmation strategy, determine the abnormal state data in the real-time data in the monitoring cluster;

[0124] Eliminate the local state corresponding to the abnormal state data from the gas path system, so as to take corresponding maintenance or adjustment measures;

[0125] Among them, the monitoring cluster condition includes:

[0126] The shortest distance between the real-time data corresponding to each other in the monitoring cluster on the time axis is less than or equal to the preset distance threshold;

[0127] The number of state types corresponding to the real-time data in the monitoring cluster is greater than 1;

[0128] The states corresponding to the first and last real-time data in the monitoring cluster are different.

[0129] The working principle of the above technical solution is as follows: First, we will collect real-time data from each component of the gas path system. For example, we can obtain the running state of the gas pump (such as opening, closing, running frequency), measure the gas pressure from the gas tank, know the cooling efficiency from the radiator, and monitor the inflation and deflation state of the air bag; Then, we place these real-time data on a preset monitoring time axis, which can be a chart showing the change of each component state over time; Next, we define the monitoring cluster on the time axis according to the monitoring cluster condition. The monitoring cluster refers to a group of data points close to each other on the time axis. If the running state of the gas pump changes frequently within a short period of time, these change points can form a monitoring cluster.

[0130] We use a preset state characterization template to process the monitoring cluster and obtain a cluster state feature set. This template can help us identify specific patterns or trends of data points, such as frequent start-stop of the gas pump may be a feature; Match the cluster state feature set with the standard state feature set in the standard state feature set library, which contains the data pattern of normal system operation.
