Description

Technical Field

[0001] The present application relates to the technical field of oxygen supply, and in particular to a medical oxygen supply method and system for automatically switching an oxygen source and an oxygen supply pipeline. Background Art

[0002] Most medical oxygen supply devices used in hospitals are equipped with two sets of oxygen sources to ensure the reliability of oxygen supply; when the oxygen supply in the first set of oxygen source is insufficient, the second set of oxygen source will be switched to replace the first set of oxygen source for oxygen supply.

[0003] The structures of the medical oxygen supply devices currently in use are generally the same, and the way to switch the oxygen source is mostly manual, or electromagnetic control using electronic technology. In actual application, people have found that after manually switching the oxygen source, there will be a situation where the switch is not in place. Since the switching process depends on external factors (such as the operator's reaction speed or the working status of the electronic equipment), it is impossible to guarantee that each switch can be completed smoothly. Especially in an emergency, any delay or error will directly affect the patient's health and even life safety.

[0004] In the existing system, even if the oxygen source switching fails, the alarm will not be triggered immediately. This is because there is a long pipeline from the oxygen source switching point to the end user. The remaining oxygen in these pipelines will maintain supply for a period of time until it is exhausted, which will trigger the hypoxia alarm. This time difference makes it difficult for medical staff to detect and deal with the problem in time, increasing the risk.

[0005] Regarding the above-mentioned related technologies, hospitals currently generally believe that the existing medical oxygen supply devices are unreliable in switching oxygen sources, especially in the face of emergencies, and cannot provide sufficient safety guarantees. Therefore, it is necessary to develop a more intelligent and reliable automatic switching medical oxygen supply method. Summary of the invention

[0006] In order to provide a more reliable and intelligent automatic switching medical oxygen supply method, the present application provides an oxygen source and oxygen supply pipeline automatic switching medical oxygen supply method and system.

[0007] In the first aspect, the invention objective of the present application is achieved by adopting the following technical solutions:

[0008] An oxygen source and oxygen supply pipeline automatic switching medical oxygen supply method, comprising:

[0009] When the oxygen source is supplied, oxygen source supply feedback information is generated, and the corresponding oxygen source supply time is obtained; based on the oxygen source supply time and a preset oxygen remaining threshold, when the oxygen remaining of the current oxygen source is lower than the preset oxygen remaining threshold, the oxygen source supply is switched, and an oxygen source switching state confirmation instruction is triggered to a preset monitoring management terminal;

[0010] Acquire abnormal feedback information of the oxygen supply system, and acquire working parameters of each component of the oxygen supply system and working information representing detection and identification content of each component of the oxygen supply system according to the abnormal feedback information;

[0011] Determine whether the oxygen supply system components corresponding to the working parameters and the working information are in normal operating state, obtain the judgment result and send it to the preset monitoring management terminal.

[0012] By adopting the above technical scheme, the present application adopts the method of automatic switching of oxygen source and manual secondary switching status confirmation after the oxygen source is switched; in order to provide a more reliable automatic switching medical oxygen supply method, and at the same time to improve the intelligence level of the medical oxygen supply system during automatic switching, the present application not only monitors and generates oxygen source supply feedback information when the oxygen source (including the main oxygen source and the backup oxygen source) is supplied, but also obtains the oxygen source supply time consumption. Based on the oxygen source supply time consumption, when the oxygen remaining amount of the current oxygen source is lower than the oxygen remaining amount threshold, the oxygen supply system can start the switching process in advance, effectively avoiding oxygen supply interruption caused by oxygen exhaustion. At the same time, after switching the oxygen supply source, the oxygen source switching status confirmation of the switching state will also be sent. The system sends a recognition command to the monitoring and management end connected to the medical staff to confirm the switching status, which is helpful to avoid the failure of oxygen source switching and to respond quickly in time when the machine fails. At the same time, it detects the abnormal conditions of each component in the oxygen supply system, obtains abnormal feedback information, and the working parameters of each component in the oxygen supply system and the working information representing the detection and identification content of each component in the oxygen supply system. According to the working parameters and working information, it determines the corresponding oxygen supply system components (including liquid oxygen storage tanks, oxygen source oxygen supply pipelines, pipeline valves and controllers, etc.) that have failed, so as to provide remote monitoring capabilities, so that hospital managers can understand the working status of each oxygen supply system component in real time and respond to any problems in a timely manner.

[0013] In a preferred example of the present application, when the oxygen source is supplied, generating oxygen source supply feedback information and obtaining the corresponding oxygen source supply time consumption include:

[0014] Each time the main oxygen source is supplied, main oxygen source supply feedback information is generated, and the main oxygen source supply time consumption is obtained;

[0015] Each time the backup oxygen source is supplied, backup oxygen source supply feedback information is generated, and the backup oxygen source supply time consumption is obtained;

[0016] Determine whether the main oxygen source supply time is within a preset supply time threshold and whether the backup oxygen source supply time is within a preset supply time threshold, and count the number of times the main oxygen source supply time is not within the preset supply time threshold and the backup oxygen source supply time is not within the preset supply time threshold, to obtain the number of oxygen supply abnormal operations;

[0017] When the oxygen supply abnormal operation frequency is greater than the preset abnormal frequency threshold, key monitoring instruction information is sent to the preset monitoring management terminal.

[0018] By adopting the above technical solution, when using the oxygen supply system, the supply time of the main oxygen source and the supply time of the backup oxygen source are judged and compared with the corresponding time thresholds to detect the abnormal shortening of the oxygen supply time of the oxygen supply system or the delay in oxygen supply switching. By accurately monitoring the actual operation of each oxygen source, any abnormal behavior is discovered and recorded in time, thereby avoiding the risk of oxygen interruption due to long-term unawareness, which is conducive to reducing the problem of abnormal oxygen supply time caused by equipment failure and improving the overall reliability of the oxygen supply system. By focusing on monitoring the number of abnormal operations, the probability of potential failure of the oxygen supply system is reduced.

[0019] In a preferred example of the present application: the working parameters of the components of the oxygen supply system include liquid oxygen tank pressure parameters, pneumatic valve state parameters and sensor working parameters, and the working information of the components of the oxygen supply system includes liquid oxygen tank level detection information, pneumatic valve switch state detection information and sensor detection information;

[0020] The determining whether the oxygen supply system components corresponding to the working parameters and the working information are in a normal operating state and obtaining a determination result specifically includes:

[0021] Determine whether the liquid oxygen tank pressure parameter, the pneumatic valve state parameter and the sensor operating parameter are within a preset normal operating parameter range, and obtain a parameter determination result;

[0022] Determine whether the liquid oxygen tank liquid level detection information is lower than a set threshold, determine whether the pneumatic valve switch state detection information conforms to the expected operation logic, and determine whether the sensor detection information includes normal ambient temperature and humidity information, and obtain the detection information judgment result;

[0023] The working parameters, the working information, the parameter judgment result and the detection information judgment result are associated to obtain a final judgment result.

[0024] By adopting the above technical scheme, the operating status of each component of the oxygen supply system is monitored. Specifically, the operating parameters of each component of the oxygen supply system (such as liquid oxygen tank pressure, pneumatic valve status and sensor operating parameters) are combined with working information (such as liquid oxygen tank level, pneumatic valve switch status and ambient temperature and humidity, etc.), and multi-dimensional data analysis is used to comprehensively judge whether the system components are in normal operating state; the present application can not only evaluate the health status of each component of the oxygen supply system separately, but also correlate and analyze it with actual working information to improve the accuracy of the status assessment of the oxygen supply system, and effectively reduce the misjudgment caused by insufficient monitoring of a single parameter in the prior art.

[0025] In a preferred example of the present application: the method further includes:

[0026] Acquire installation information and design parameters of the oxygen supply system, and determine a first predicted switching time when the main oxygen source is insufficiently supplied and a second predicted switching time when the backup oxygen source is enabled according to the installation information and the design parameters of the oxygen supply system;

[0027] generating an oxygen supply switching strategy for adjusting the oxygen supply switching process according to the design parameters, the first predicted switching time and the second predicted switching time;

[0028] Acquiring a switching speed change reference range representing an oxygen supply switching speed change threshold, and generating an oxygen supply control switching model based on the switching speed change reference range and the oxygen supply switching strategy;

[0029] A first actual oxygen surplus is obtained, and the first actual oxygen surplus is input into the oxygen supply switching control model to adjust the speed of the oxygen supply switching.

[0030] By adopting the above technical scheme, in order to further ensure the stability and high efficiency of the oxygen supply system in the process of switching oxygen supply; taking into account the differences in different application scenarios, such as pipeline length, valve position, pipe diameter and other factors, the ability to dynamically adjust the switching strategy is realized, and the adaptability and flexibility of the system are improved; specifically, since the oxygen source oxygen supply pipeline of the oxygen supply system will be laid for a long time in actual application (the total length will be two or three kilometers long), and the longer or thinner pipeline will increase the resistance of gas flow, resulting in a slower switching speed, on the contrary, the short and thick pipeline will help to speed up the switching speed; and when the oxygen source is switched, if there is a significant pressure difference between the main oxygen source and the backup oxygen source, it will also affect the oxygen delivery speed, and the different oxygen delivery speeds before and after will reduce the patient experience, so in order to use a reasonable oxygen source switching speed, prevent flow fluctuations or pressure changes caused by too fast or too slow switching, maintain a stable oxygen supply, and at the same time, the appropriate switching speed can maximize the use of the remaining oxygen in the main oxygen source to avoid waste; therefore, the present invention controls the oxygen supply switching speed of the entire oxygen supply system through an intelligent oxygen supply control switching model, and the optimized switching strategy reduces unnecessary energy consumption and equipment wear, and reduces operating costs.

[0031] In a preferred example of the present application, the step of obtaining installation information and design parameters of the oxygen supply system, and determining a first predicted switching time when the main oxygen source is insufficiently supplied and a second predicted switching time when the backup oxygen source is enabled according to the installation information and the design parameters of the oxygen supply system, specifically includes:

[0032] Acquire installation information and design parameters of the oxygen supply system, wherein the installation information of the oxygen supply system includes the type of the oxygen supply system, the length of the pipeline, the distance between the main oxygen source and the backup oxygen source, and the position and state of each valve, and the design parameters include the design margin of the main oxygen source, the first design switching time, and the second design switching time;

[0033] Determining a first predicted switching time when the main oxygen source is insufficiently supplied according to the first designed switching time, the length of the pipeline, and the distance between the main oxygen source and the backup oxygen source;

[0034] The second predicted switching time when the backup oxygen source is activated is determined according to the type of the oxygen supply system, the second designed switching time, the length of the pipeline, and the position and status of each valve.

[0035] By adopting the above technical solution, key factors such as pipeline length, distance between the main oxygen source and the backup oxygen source, and the position and status of each valve are comprehensively considered to accurately predict the specific time points when the main oxygen source is insufficient and the backup oxygen source is activated; reasonable switching time and speed control can ensure a smooth transition of oxygen supply during the switching process, prevent flow fluctuations or pressure changes caused by improper switching, and maintain a stable oxygen supply.

[0036] In a preferred example of the present application, the oxygen supply switching strategy for adjusting the oxygen supply switching process based on the design parameters, the first predicted switching time and the second predicted switching time is generated, specifically including:

[0037] Acquire a predicted switching completion time according to the pipeline length, the first predicted switching time and the second predicted switching time, and acquire a designed switching completion time according to the first designed switching time and the second designed switching time;

[0038] Obtaining a predicted oxygen supply switching speed according to the designed margin of the main oxygen source, the predicted switching completion time, and the designed switching completion time;

[0039] Calculating a ratio of the first predicted switching time to the second predicted switching time to obtain a predicted switching time ratio for predicting a second actual switching speed;

[0040] Calculate the switching time difference between the predicted switching completion time and the designed switching completion time, and calculate the switching speed difference between the oxygen supply switching predicted speed and the second actual switching speed of the main oxygen source design margin;

[0041] According to the switching time difference and the switching speed difference, a predicted switching speed-time correspondence for determining an actual speed of oxygen supply switching is obtained;

[0042] According to the predicted switching time ratio and the predicted switching speed time correspondence, an oxygen supply switching strategy for controlling and adjusting the oxygen supply switching process is generated.

[0043] By adopting the above technical solution, the speed and timing of oxygen supply switching are accurately calculated and optimized, which effectively solves the problems of uncontrollable switching speed and lack of intelligent adjustment mechanism in the prior art; based on detailed switching time ratios and switching speed differences, the system can dynamically adjust the speed of oxygen supply switching to ensure a smooth and efficient switching process. By generating an oxygen supply switching strategy, the system can flexibly adjust various parameters in the switching process according to actual conditions, thereby improving the adaptability and reliability of the system and ensuring stable oxygen supply in different application scenarios.

[0106] S206: Generate an oxygen supply switching strategy for adjusting the oxygen supply switching process according to the predicted switching time ratio and the predicted switching speed time correspondence.

[0107] An example application scenario is used to illustrate the technical application of this embodiment:

[0108] Assume that in a hospital ICU environment, the length of the pipeline between the primary oxygen source and the backup oxygen source may be long. For example, assume that the pipeline length is 2.5 kilometers long and the various parameters in the current oxygen supply system are:

[0109] First predicted switching time: The system predicts that the main oxygen source will be exhausted within 10 minutes.

[0110] Second predicted switching time: After the backup oxygen source is activated, it is estimated to take 5 minutes to completely take over the oxygen supply task.

[0111] Predicted switching completion time: Taking into account the pipeline length and other factors, the actual switching completion time is calculated to be 15 minutes.

[0112] First, design switching time: According to the design specifications, theoretically, the switch from the main oxygen source to the backup oxygen source should be completed within 8 minutes.

[0119] Oxygen supply switching predicted speed: Through calculation, the system obtains the oxygen supply switching predicted speed of about 6.67 liters per minute (100 liters / 15 minutes).

[0120] In step S203:

[0121] The first predicted switching time is 10 minutes.

[0122] The second predicted switching time is 5 minutes.

[0123] Predicted switching time ratio: The calculated ratio is 2 (10 minutes / 5 minutes).

[0124] Predict the second actual switching speed: If the switching speed of the main oxygen source is 6.67 L / min, the switching speed of the backup oxygen source should be 3.33 L / min (6.67 L / min ÷ 2).

[0125] In step S204:

[0126] Estimated switching completion time: 15 minutes.

[0127] Design switch completion time: 12 minutes.

[0128] Switching time difference: The calculated difference is 3 minutes (15 minutes - 12 minutes).

[0129] Oxygen supply switching predicted speed: 6.67 L / min.

[0130] Main oxygen source design margin: 100 liters.

[0132] Switching speed difference: The calculated switching speed difference is 3.34 l / min (6.67 l / min - 3.33 l / min).

[0133] In step S205: if the switching time difference is 3 minutes and the switching speed difference is 3.34 liters / minute, the system determines that the actual switching speed is 6.67 liters / minute.
