Description

Technical Field

[0001] This application relates to the field of medical device testing, and more particularly to a reliability testing apparatus and an electrically mobile medical device. Background Technology

[0002] For electrically powered mobile medical devices, the steering wheel is a key moving component responsible for steering and movement control.

Detailed Implementation

[0016] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0017] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0018] It should be understood that although the terms first, second, third, etc., may be used in this application to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0019] For electrically powered mobile medical devices, the steering wheel, as a critical moving component, is responsible for the device's steering and movement control. Its reliability determines whether the device can move accurately and stably along a predetermined path under various environments. If the steering wheel experiences performance degradation, accuracy deviation, or mechanical failure during long-term use, it will directly lead to the entire device losing its controllable movement capability. Therefore, verifying its stable operation throughout its entire design lifecycle during the development phase is a crucial requirement for ensuring the overall reliability of the medical device.

[0020] The primary problem with traditional testing methods is the conflict between the testing cycle and the design life. Medical devices are often designed for a lifespan of more than ten years, making routine testing for the same duration impractical in terms of both time and cost. Therefore, accelerated life testing is necessary. This involves subjecting the steering wheel to more frequent start-stop cycles, more complex steering sequences, and longer continuous operation times than normal use during the testing period, thus simulating and compressing the wear and aging process that occurs over many years of use.

[0021] However, if an unattended method is used during testing, the equipment may deviate from its movement path due to control errors, potentially leading to dangerous situations such as collisions with the surrounding environment. This risk not only affects the safety of the test but also makes long-term, continuous reliability verification difficult to implement.

[0022] Therefore, there is an urgent need for a testing method that can operate safely, continuously, and automatically without relying on manual monitoring, in order to solve the difficulties faced in the reliability verification of steering wheels.

[0023] The embodiments described in this specification will now be described in detail.

[0024] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating the structure of a reliability testing apparatus according to an exemplary embodiment of this specification. The apparatus is used to perform reliability testing on the steering wheel of an electrically powered mobile medical device.

[0025] The device includes a UPS power supply, a magnetic path, a magnetic induction component, a control component, and a drive component.

[0026] The high-capacity UPS power supply carried by the electric mobile medical device is connected to the main power system of the medical device via a cable. It is used to provide continuous power to components such as magnetic induction components, control components, and drive components during testing, ensuring that reliability testing can be carried out uninterrupted for a long time without human intervention.

[0027] The magnetic path is used to generate a magnetic field. The magnetic path is a path composed of magnetic material pre-laid on the ground of the test site, which can form a stable and continuous spatial magnetic field. Figure 2 This is a schematic diagram of an application example in this manual. The magnetic path can be a closed loop, and the medical device under test can continuously circulate along this closed path. Figure 2 The arrow in the diagram exemplarily indicates the direction of travel for the medical device. For example, the UPS power supply, magnetic induction component, control component, and drive component may be integrated into the medical device.

[0028] The magnetic induction component, located at the bottom of the medical device, detects the magnetic field signal and converts it into an electrical signal, which is then sent to the control component. The magnetic induction component may be a sensor array comprising multiple Hall effect sensors, rigidly connected and fixed beneath the chassis of the medical device under test. It can detect the magnetic field generated by the magnetic path on the ground, convert it into an electrical signal, and after filtering, amplification, and other processing, send it to the control component.

[0029] The control component generates control commands based on the electrical signals and sends them to the drive component. The control component may include a microprocessor, memory, and related input / output interface circuits. The control component establishes an electrical connection with the magnetic induction component and the drive component via physical lines or a wireless communication module, forming a complete information transmission path. The control component can be installed in the medical device under test or can be set up independently of the medical device under test; this embodiment does not impose any limitations on this.

[0030] The driving component is used to drive the medical device to move under the control of the control command. The driving component is the part that moves the steering wheel of the medical device under test, and includes a motor, a transmission mechanism, and a corresponding drive circuit. In this embodiment, the driving component is configured to receive control commands from the control component and control the steering wheel according to the control commands.

[0031] The device described in this specification operates on the principle of a closed-loop automatic control process. This process begins with the continuous detection of the ground magnetic field signal by the magnetic induction component. As the medical device moves along the test path, the magnetic induction component at its bottom senses its position relative to the ground magnetic path in real time. If the actual movement trajectory of the device deviates from the preset magnetic path, the intensity of the magnetic field signal detected by each Hall sensor in the magnetic induction array will differ accordingly. Based on this, the magnetic induction component converts these magnetic field signals representing position changes into corresponding electrical signals and sends them to the control component.

[0032] Upon receiving the electrical signal, the control unit analyzes and calculates it in real time according to its pre-set processing method, thereby identifying the current offset direction and amount of the device relative to the magnetic path. Based on this identification result, the control unit generates a corresponding control command, which is an electrical signal used to adjust the steering wheel's movement. This control command is sent to the drive unit in real time.

[0033] The drive component, acting as an actuator, responds to control commands from the control component by adjusting the steering angle or travel speed of the steering wheel, thereby driving the medical device back to the center line of the magnetic path.

[0034] This embodiment of the specification uses a magnetic induction element located at the bottom of the device to detect the magnetic field generated by the magnetic path in real time, convert it into an electrical signal and transmit it to the control unit. The control unit generates control commands based on the electrical signals, enabling the drive components to move the medical device under the control of the control commands, forming a closed-loop navigation control circuit. This allows the medical device to operate stably on the magnetic path, avoiding the risk of collisions caused by path deviation during testing. At the same time, in conjunction with a high-capacity uninterruptible power supply, it enables long-term, safe and continuous reliability testing of the steering wheel under unattended conditions.

[0035] like Figure 3 As shown, Figure 3 This is a schematic diagram of another reliability testing apparatus illustrated in an exemplary embodiment of this specification. As one or more embodiments of this specification, the apparatus further includes an anomaly detection component for sending a detected anomaly signal to the control component; the control component is further configured to correct the control command based on the anomaly signal.

[0036] The anomaly detection component establishes a stable electrical connection with the control component in the device via physical wiring or a wireless communication module. In terms of hardware configuration, the anomaly detection component may include specific sensing elements and signal processing circuits, designed to monitor physical quantities or events that may deviate from preset normal operating conditions during testing. Upon receiving this anomaly signal, the control component integrates it with the electrical signal from the magnetic induction component. Thus, the control component's purpose extends beyond path tracking, adding a response strategy for abnormal states. Based on the received anomaly signal, the control component adjusts or overrides the control commands originally generated solely based on navigation signals in real time, thereby outputting a corrected control command to the drive component.

[0037] As one or more embodiments of this specification, the anomaly detection component includes a power detection module; the anomaly signal includes a power anomaly signal; the power detection module is used to generate the power anomaly signal when the power of the UPS power supply is abnormal.

[0038] The anomaly detection component integrates a power detection module for UPS power supply testing. For example, the power detection module can consist of a voltage sensor, a current sensor, a signal conditioning circuit, and a comparison circuit. It is directly connected via physical wires to the output terminal or battery pack of the UPS power supply carried by the medical device to collect its electrical parameters such as voltage and current in real time. If the UPS power supply's charge level falls below the minimum threshold required for safe testing, or if abnormal fluctuations occur in the power output, the comparison circuit inside the module will trigger, immediately generating a power anomaly signal and sending it to the control unit.

[0039] Upon receiving this abnormal power signal, the control unit will modify the control command originally generated solely based on the electrical signal from the magnetic induction component. This will then control the drive component to decelerate the medical device and bring it to a smooth stop at a safe position. This prevents equipment malfunction, data loss, or test interruption due to sudden power outages, ensuring the safety and integrity of the testing process.

[0040] As one or more embodiments of this specification, the anomaly detection component includes an obstacle avoidance module; the anomaly signal includes an obstacle avoidance signal; the obstacle avoidance module is used to generate the obstacle avoidance signal when an obstacle is detected on the magnetic path.

[0041] The obstacle avoidance module can consist of ranging sensors installed at the front or sides of the mobile medical device in locations prone to collisions. As the device automatically travels along the magnetic path, the obstacle avoidance module continuously emits detection signals forward and receives reflected echoes. When an unexpected obstacle appears on the magnetic path, the reflected echo is captured and analyzed by the module's processing circuitry, thus determining the obstacle's presence.

[0042] When an obstacle is detected entering a preset safe distance range, the obstacle avoidance module generates an obstacle avoidance signal and sends it to the control unit. Upon receiving this signal, the control unit corrects its control commands, causing the drive unit to decelerate or stop the equipment completely. This ensures that the equipment can automatically avoid sudden obstacles, providing a safety guarantee for long-term unattended testing.

[0043] As one or more embodiments of this specification, the magnetic path includes permanent magnet strips and magnetic markers. The permanent magnet strips are the main body of the magnetic path and can be elongated structures, laid on the ground according to a preset test route. Their function is to generate a continuous and stable guiding magnetic field in space. The magnetic markers are independent point-like or small block-like permanent magnets, discretely arranged at specific locations in the magnetic path, such as the beginning, end, or turning points of the path.

[0044] During equipment movement, a magnetic induction component at the bottom of the device detects the continuous magnetic field generated by the permanent magnet strips to obtain a continuous guiding signal necessary for maintaining straight-line travel. When the device reaches a specific location marked with a magnetic marker, the magnetic induction component detects a magnetic field signal that differs from the continuous magnetic field signal of the permanent magnet strips. This magnetic field signal, triggered by the magnetic marker, is transmitted to the control unit, which identifies it as a specific location marker. This allows the system to not only perform basic line-following functions but also execute more complex logic control, such as starting to record the test cycle at the beginning of the path, automatically stopping at the end, or adjusting the speed in advance at turning points, thereby improving the automation and accuracy of the testing process.
