[0024] In this solution, when a person on a mobile medical device is detected to be at risk of falling from the edge of the bed, a fall detection module is set up to issue a fall alarm, thereby preventing the person from falling and improving safety during the transfer process.
[0025] Optionally, the warning system further includes a personnel identification module electrically connected to the control module. The personnel identification module is used to communicate with the wearable device of the person on the mobile medical device to obtain personnel information and transmit the personnel information to the control module.
[0026] In this solution, by setting up a personnel identification module and pairing it with wearable devices for the transferred personnel, the information of the transferred personnel can be quickly identified to achieve automatic identification of transfer needs.

[0056] Self-propelled medical device 2 Detailed Implementation
[0057] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the warning system for self-propelled medical devices and the self-propelled medical device itself, based on the present invention. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, intended only to facilitate and clearly illustrate the embodiments of the present invention. Please refer to the drawings to make the objectives, features, and advantages of the present invention more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of the present invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by the present invention, should still fall within the scope of the technical content disclosed in the present invention.
[0058] This invention provides a warning system for self-moving medical devices. The self-moving medical device 2 includes, but is not limited to, automatically movable hospital beds, ultrasound equipment, CT equipment (X-ray Computerized Tomography Scanner), small head CT scanners, small C-arms, X-ray machines, etc. The warning system 1 is installed on the self-moving medical device 2 to prevent collisions with surrounding personnel when the self-moving medical device 2 moves within the hospital area or elsewhere, or to prevent pedestrians from bumping into the self-moving medical device 2 when it is stationary.
[0059] Specifically, such as Figure 1As shown, the warning system 1 includes an ambient environment perception module 20, a projection module 40, an interaction module 10, and a control module 30. The ambient environment perception module 20 is used to perceive the environment surrounding the mobile medical device 2 and generate perception signals. The ambient environment perception module 20 includes a radar component and / or a visual perception component. The radar component includes millimeter-wave radar, which detects nearby people by emitting high-frequency electromagnetic waves (wavelength 1–10 mm) and receiving the echo signals reflected from human bodies. Alternatively, the radar component may include ultra-wideband (UWB) radar, Doppler radar, infrared radar, or microwave radar, as long as it can detect human bodies; no limitation is made here. The visual perception component includes a camera, which collects surrounding video data and, combined with a visual recognition algorithm, uses computer vision and deep learning models to identify nearby pedestrian traffic.
[0060] The interactive module 10 is used to generate interactive signals with the surrounding environment. The interactive module 10 includes a first light interactive component 110. For example... Figure 2 As shown in this embodiment, a self-moving hospital bed is used as an example of a self-moving medical device 2. The first lighting interaction component 110 is used to generate driving status indicator lights and warning lights according to the driving status. Specifically, the first lighting interaction component 110 is a driving status indicator light installed at both ends of the hospital bed. When the self-moving hospital bed is moving, the driving status indicator light flashes to remind the surrounding crowd that the device is moving and to remind the surrounding crowd to avoid colliding with the device during movement. The warning light is used to issue warning information to the surrounding crowd.
[0061] The projection module 40 includes a first projection component 410, which is mounted on the bottom side of the mobile medical device 2 and is used to project the movement direction of the mobile medical device 2 onto the ground. Figure 4 As shown, the arrow projected by the first projection component 410 on the ground is used to indicate the direction of movement of the mobile medical device 2. The first projection component 410 and the second light interaction component 120 work together to indicate the direction of movement of the mobile medical device 2 to the surrounding crowd more clearly, reminding the surrounding crowd to plan their movement route in advance and avoid collisions.
[0062] The control module 30 is electrically connected to the surrounding environment sensing module 20, the interaction module 10, and the projection module 40. The control module 30 receives moving target signals and sensing signals. The control module 30 controls the movement of the self-propelled medical device 2, controlling the interaction module 10 to generate corresponding interaction signals based on the sensing signals and controlling the projection module 40 to project the movement direction of the self-propelled medical device 2 onto the ground. For example, when the self-propelled medical device 2 is in motion, the control module 30 can control the driving direction based on the movement path.
[0063] In one embodiment, the control module 30 can generate a movement path and perform path planning based on the moving target signal.
[0064] In another embodiment, the interactive module 10 further includes a second light interactive component 120, such as... Figure 2 and Figure 3 As shown, the second lighting interaction component 120 includes a movement direction indicator light, which is used to generate the movement direction indicator light according to the movement path. The second lighting interaction component 120 can be, for example, a turn signal. In this embodiment, a self-moving hospital bed is used as an example of a self-moving medical device 2. The turn signal can be a turn signal installed on both sides of the length direction of the hospital bed, or it can be a long strip turn signal directly installed on both sides of the width direction of the hospital bed. When the self-moving hospital bed turns to the left or right, the turn signal on the corresponding side will light up and flash to remind the surrounding people of the movement direction of the self-moving medical device 2 and to pay attention to avoid collisions.
[0065] In one embodiment, the projection module 40 further includes a second projection component 420 for mounting on the self-propelled medical device 2. Figure 3 As shown, the second projection component 420 projects the trajectory line of the mobile medical device 2 onto the ground. After the control module 30 plans and forms the movement path, it controls the second projection component 420 to project the expected movement trajectory line onto the ground, which is the preset movement path of the mobile medical device 2. If people are standing in the area between the movement trajectory lines, the sound prompt device built into the mobile medical device 2 will emit a warning sound to remind people to avoid it, and the first light interaction component 110 will light up the movement status indicator light to remind people to avoid it. In addition, people in the vicinity can also judge the movement direction of the mobile medical device 2 based on the movement trajectory line projected on the ground by the second projection component 420 and actively avoid it to prevent collisions. The width between the movement trajectory lines can be adjusted according to actual conditions, such as the movement speed of the mobile device, the density of people in the vicinity, or other parameters. Of course, other adjustment methods are also possible and are not limited here.
[0066] In addition, the control module 30 can also change the width of the driving trajectory line according to other surrounding information, such as the change in distance between people and equipment, the light sensitivity of the indoor environment where the equipment is located, and the change in ambient light during the day and night, to match different levels of sound and light warning intensity.
[0067] The warning system 1 also includes a human-machine interface module 50, which includes a display component 510 and a support component 520. One end of the support component 520 is connected to the display component 510, and the other end is used to connect to the self-propelled medical device 2. The support component 520 is used to connect the display component 510 and the self-propelled medical device 2. The support component 520 can be a universal bracket, so that the relative position between the display component 510 and the self-propelled medical device 2 can be adjusted as needed. The display component 510 is electrically connected to the control module 30 to obtain relevant information from the control module 30. The display component 510 is used to display the usage information, destination, and status information of the self-propelled medical device 2. In addition, such as Figure 3 As shown, the display component 510 can be made into a soft, anthropomorphic shape to enhance passive pedestrian protection and, combined with screen content, provide a more user-friendly human-computer interaction experience.
[0068] The warning system 1 also includes a wireless transmission module 60, which is electrically connected to the control module 30. The wireless transmission module 60 is used to achieve wireless connection between the control module 30 and an external console. Through the wireless transmission module 60, communication with the nurse call system can be achieved, enabling two-way synchronization of alarm information. Furthermore, when the self-propelled medical device 2 encounters an obstacle, it can send fault information to seek assistance.
[0069] The warning system 1 also includes a fall detection module 70 electrically connected to the wireless transmission module 60. When the mobile medical device 2 is a hospital bed or other equipment capable of supporting people, the fall detection module 70 is installed on the mobile medical device 2 to detect the risk of falls from the person on the mobile medical device 2. When a fall risk is detected, a fall alarm signal is generated and transmitted to an external control console via the wireless transmission module 60. For example, the fall detection module 70 includes an expandable force sensor installed on the guardrail or bed frame. When a patient moves to the edge of the bed where there is a risk of fall, the patient will press on the force sensor, thereby detecting whether the patient is at risk of falling and providing a warning.
[0070] exist Figure 5 In the embodiment shown, the self-moving medical device 2 is a self-moving miniature C-arm; Figure 6 In the illustrated embodiment, the self-propelled medical device 2 is an X-ray machine. This indicates that the warning system 1 of this application can be installed on various self-propelled medical devices 2, and does not limit the specific type of self-propelled medical device 2.
[0071] The alert system 1 also includes a personnel identification module 80 electrically connected to the control module 30. The personnel identification module 80 communicates with the wearable devices of personnel on the mobile medical device 2 to obtain personnel information and transmits this information to the control module 30. The personnel identification module 80 identifies the information of the patients being transported, enabling automatic identification of transport needs. Furthermore, it can provide tiered alerts based on the patient's risk level, such as setting stronger alerts for critically ill patients to facilitate rapid transport.
[0072] This application provides an alert system 1 for a self-propelled medical device 2, which is applicable to the self-propelled medical device 2, improves the safety of the self-propelled medical device 2 during movement, reduces the number of personnel required for the self-propelled medical device 2, and is suitable for future labor shortage scenarios, such as the transfer of personnel from infected areas, thereby reducing the risk of infection for medical staff.
[0073] This application also provides a self-moving medical device, which includes a self-moving medical device body and an alarm system for the self-moving medical device. The alarm system is installed on the medical device body. The alarm system 1 provided in this application can be attached to the self-moving medical device body, for example, by means of magnetic attraction, snap-fit, or quick-release mechanism, thereby realizing the functional expansion of the existing medical device. Alternatively, it can be integrated into the self-moving medical device body. No limitation is made on the installation method adopted.
