Description

Technical Field

[0001] The present invention relates to the technical field of medical device management, and specifically to an artificial intelligence-based medical device management system. Background Art

[0002] With the continuous development of Internet technology, the management of medical devices has gradually become informatized. However, as the division of medical devices becomes more and more detailed, the variety and quantity of medical devices are also increasing, resulting in the limited medical engineering staff in hospitals being exhausted in managing and adjusting a large number of medical devices. Moreover, some devices in some departments have been idle, wasting a large amount of medical resources. However, due to factors such as road conditions and poor supervision effects of devices after adjustment in cross-hospital area transfers, the prior art can only perform device transfers within the current hospital area. Therefore, there will still be idle phenomena of medical devices, and the distribution of medical resources is very unreasonable. And during the process of adjusting devices, due to the incompatibility between the devices and the management system or encryption system of the new hospital area, there will be a short-term weakness in data protection, resulting in the leakage of patients' privacy information. Moreover, the prior art maintains the devices by suspending services and cannot select the maintenance time period by predicting the time required for device maintenance, resulting in uncertainty in the waiting time for patients to undergo examinations. Therefore, it is very necessary to design an artificial intelligence-based medical device management system that can improve resource utilization and reasonably select the maintenance time.

The apex of the convex slope road surface part and the lowest point of the concave road surface part are anchored, and a coordinate system is established with the convex point or the apex of the lowest concave point as the origin. The inflection point A (X, Y) between the slope road surface or the concave road surface and the horizontal road surface is marked in the coordinate system, and the road surface slope is calculated by the formula In the formula, P represents the slope of the road, α represents the slope coefficient, and the system sets a threshold. If P is less than the minimum threshold, the pending route is deleted, otherwise the road depression degree is calculated;

[0019] Step S23: Further select the route according to the number of road depressions, retrieve the coordinate system model of the road depression part, mark the intersection point D(x, y) of the depression edge and the horizontal road surface, and calculate the road depression degree value by the formula Where U represents the road depression value, β represents the road depression coefficient, and compared with the system set threshold, if U is less than the system set threshold, the current pending route is deleted, otherwise a road is selected in the pending route according to the road traffic conditions.

[0028] Step S421: Further retrieve the scheduled time periods of the patients who need to use the current device, calculate the interval duration between two adjacent time periods, compare it with the maintenance duration required for the current device. If there is an interval duration equal to the maintenance duration required for the current device, mark the device as maintainable and issue a reminder. Otherwise, wait until the maintenance date for maintenance. After maintenance, the system detects each component on the device. If a component code appears for the first time, record the component code and component location and save them;

[0029] Step S422: During the use of the device, retrieve the air composition data, temperature, and humidity around the device, and compare them with the system thresholds. If the ambient temperature or humidity around the device is greater than the threshold, trigger the alarm module to remind the management personnel that the device temperature is too high or the humidity is too large.

[0039] The data protection module includes an authorization instruction sub-module, a relay chain sub-module, and a transmission node sub-module. The authorization instruction sub-module is used to lock the transmission interface of the device and open the restrictions of the transmission interface through instructions. The relay chain sub-module is used to establish a relay chain to provide a line for data transmission and protect data security. The transmission node sub-module is used to establish transmission nodes and adjust the adaptability of the system;

[0040] The maintenance module includes a maintenance time calculation sub-module and a device environment monitoring sub-module. The maintenance period selection sub-module is used to select the maintenance period of the device. The device environment monitoring sub-module is used to detect whether the device operating environment meets the device operation requirements.

[0041] The operation method of the medical device management system mainly includes the following steps:

[0042] Step S1: Through the device information entry module, enter the device model, transportation conditions, lifecycle, and maintenance records of the device into the system. Through the sensor module, collect the air composition, temperature, and humidity of the device operating environment in real time. The system retrieves the transportation conditions, lifecycle, and maintenance records of the device based on the device model, and retrieves the three-dimensional remote sensing image and road traffic conditions of the transportation route through satellite.

[0043] Step S2: When selecting a transportation plan, the system triggers an electrical signal to start the transportation management module, begins to analyze the transportation conditions of the device, and then analyzes the three-dimensional remote sensing image of the road surface according to the transportation conditions of the device.

[0044] Step S3: When the device is installed, the authorization instruction sub-module activates the locking device data transmission interface, uses the relay chain as the transmission channel to transmit data, and adjusts the adaptability of the system using the transmission node.

[0045] Step S4: When performing maintenance and servicing on the device within the cycle, the system activates the maintenance module, and begins to analyze the impact of the number of device uses, usage duration, and time since the last maintenance on the required duration of device maintenance, and analyzes the impact of the device operating environment on the device failure rate and lifespan.

[0046] Step S2 further includes the following steps:

[0047] Step S21: Retrieve the transportation conditions of the device, scan and identify the size and specifications of the device, select the size of the transportation vehicle according to the size and specifications of the device, scan the length, width, and height data of the transport vehicle after loading, further retrieve the width limit and height limit data of the transportation route, and screen out the eligible routes according to the length, width, and height data of the transport vehicle, and mark them as pending routes. Screening the transportation route through the length, width, and height data of the transport vehicle can prevent the transport vehicle from being unable to pass through narrow roads or height-limited roads during the transportation of the device, and improve the transportation efficiency of the device.

[0048] Step S22: After initially screening out the pending routes, retrieve the three-dimensional remote sensing image of the road surface, scan and mark the convex slope road surface and sunken road surface in the image, anchor the vertex of the convex slope road surface part and the lowest point of the sunken road surface part of the sunken road surface, establish a coordinate system with the lowest point or vertex of the convex part of the sunken road surface as the origin, mark the inflection point A(X, Y) of the slope road surface or sunken road surface and the horizontal road surface in the coordinate system, and calculate the road surface slope through the formula In the formula, P represents the slope of the road surface, and α represents the slope coefficient. Compare with the system-set threshold. If P is less than the minimum threshold, it means that the road slope is too large, and delete the pending route. Otherwise, calculate the degree of road surface depression. By calculating the slope of the convex surface of the road, it is possible to avoid selecting a route with a bumpy road surface that is likely to damage the device and prevent the device from being damaged.

[0049] Step S23: Further select the route according to the number of road depressions, retrieve the coordinate system model of the road depression part, mark the intersection point D(x, y) of the depression edge and the horizontal road surface, and calculate the road depression degree value by the formula Where U represents the depression degree of the road surface, β represents the depression coefficient of the road surface, and compared with the threshold value set by the system, if U is less than the threshold value set by the system, it means that the road surface is deeply depressed and bumpy, and the current pending route is deleted.

[0050] Step S3 further comprises the following steps:

[0051] Step S31: After the device is transported to the destination, the system authorization instruction is retrieved and injected into the current device. The authorization instruction anchors the device data interface and releases the data port restriction. The system establishes a virtual transmission channel with the data port through the virtual transmission network.

[0052] Step S32: After establishing a connection with the data port, the system establishes a relay chain through the relay chain module, and uses the relay chain to wrap the virtual transmission channel. The relay chain can form a protection layer outside the virtual transmission channel, and can block all access requests outside the system. If there is a terminal device that wants to access or attack the virtual transmission channel at this time, the relay chain will collect the access request and put it into an isolation box that can isolate the terminal device from the access request for destruction. By establishing a relay chain to protect the virtual transmission channel, the patient's privacy data can be protected from being stolen during the debugging of the device, thereby avoiding the leakage of patient privacy;

[0056] Step S42: When the current device is (y - 1) days from the most recent maintenance, retrieve the cumulative usage times S, total usage duration t, maintenance cycle Y, and the time y since the most recent maintenance cycle of the current device from the time of purchase to the present, and calculate the maintenance time required for the current device through a formula In the formula, i = 0, 1, 2, 3......n, T represents the maintenance time required for the current device, y represents the number of days since the most recent maintenance cycle, λ S represents the influence coefficient of the usage times on the maintenance duration required for the current device, μ t represents the influence coefficient of the total usage duration of the device on the maintenance duration required for the current device, T 定 represents the fixed maintenance duration required for the current device, Y represents the maintenance cycle of the current device, J i represents the fixed duration required to repair the faulty parts of the current device. By calculating the maintenance duration required for the current device, it enables the management staff to arrange the maintenance time period according to the maintenance duration required for the current device.

[0057] Step S42 further includes the following steps:

[0058] Step S421: Further retrieve the appointment time periods of the patients who need to use the current device, calculate the interval duration between two adjacent time periods, compare it with the maintenance duration required for the current device. If there is an interval duration that is the same as the maintenance duration required for the current device, it means that the device can complete the device maintenance within the interval duration, mark the device as maintainable and send a reminder. Otherwise, wait until the maintenance date for maintenance. After the maintenance, the system detects each component on the device. If a component code appears for the first time, record the component code and component location and save them. By calculating the interval between the appointment time periods of two adjacent patients, it is possible to select a suitable time for maintenance within the time interval according to the device maintenance duration, without affecting patient treatment, and greatly improving the utilization rate of the device;

[0059] Step S422: During the use of the device, retrieve the air composition data, temperature, and humidity around the device, and compare with the system thresholds. If the ambient temperature or humidity around the device is greater than the threshold, trigger the alarm module to remind the management staff that the device temperature is too high or the humidity is too high.
