The server compares the location information of the mobile medical device this time with the location information of the mobile medical device obtained last time. If the location information of the mobile medical device this time is different from the location information of the mobile medical device obtained last time, the location information of the mobile medical device this time will overwrite the location information of the mobile medical device obtained last time, and the location information of the mobile medical device this time will be fed back to the client; if the location information of the mobile medical device this time is the same as the location information of the mobile medical device obtained last time, the location information of the mobile medical device this time / or last time will be fed back to the client.

When the battery power is lower than the low power threshold, the control module controls the Bluetooth positioning module to perform a single positioning, and the communication module uploads the location information of the mobile medical device to the server, and then enters a low power consumption state. After the server obtains the location information of the mobile medical device, it displays the current location of the mobile medical device on the display device and issues a low power alarm message.

[0009] Preferably, after the communication module of the mobile medical device receives the positioning instruction, the control module controls the Bluetooth positioning module to perform single positioning, and the communication module uploads the location information of the mobile medical device to the server. The positioning instruction is sent to the mobile medical device according to the usage requirements of the mobile medical device after the server obtains the usage requirement information of the mobile medical device sent by the client; the server compares the location information of the mobile medical device this time with the location information of the mobile medical device obtained last time. If the location information of the mobile medical device this time is different from the location information of the mobile medical device obtained last time, the location information of the mobile medical device this time will overwrite the location information of the mobile medical device obtained last time, and the location information of the mobile medical device this time will be fed back to the client; if the location information of the mobile medical device this time is the same as the location information of the mobile medical device obtained last time, the location information of the mobile medical device this time / or last time will be fed back to the client.

DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0016] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0017] like Figure 1~2As shown, the present invention provides a method for positioning a mobile medical device, wherein the mobile medical device is provided with a backup battery, a power management module, a gyroscope, a Bluetooth positioning module, a control module, and a communication module, wherein the control module is signal-connected with the power management module, the gyroscope, the Bluetooth positioning module, and the communication module respectively, and the backup battery is electrically connected with the power management module, the gyroscope, the Bluetooth positioning module, the control module, and the communication module respectively, and the method comprises: The power management module detects whether there is current in the power line of the mobile medical equipment; If there is current in the power line of the mobile medical device, the power management module uses the mains electricity to power itself and the gyroscope, Bluetooth positioning module, control module, and communication module. The control module controls the Bluetooth positioning module to perform positioning, and the communication module uploads the location information of the mobile medical device to the server. If there is no current in the power line of the mobile medical device, the power management module uses a backup battery to power itself and the gyroscope, Bluetooth positioning module, control module, and communication module. The control module periodically obtains motion information collected by the gyroscope and determines whether the mobile medical device is moving based on the motion information. If the mobile medical device does not move, the control module controls the Bluetooth positioning module to perform a single positioning, and the communication module uploads the location information of the mobile medical device to the server, and then enters a low power consumption state; If the mobile medical device moves, the control module controls the Bluetooth positioning module to perform real-time positioning, and the communication module uploads the location information of the mobile medical device to the server.

[0018] Specifically, the backup battery can be a 3.3V DC power supply battery, and a 220~3.3V AC to DC power supply module can also be set in the mobile medical care device. After the power cord of the mobile medical care device is connected to the mains, the mains passes through the 220~3.3VAC to DC power supply module to supply power to the power management module, gyroscope, Bluetooth positioning module, control module, and communication module. When a power outage occurs or the power cord of the mobile medical care device is disconnected from the mains, the 3.3V DC power supply battery supplies power to the power management module, gyroscope, Bluetooth positioning module, control module, and communication module.

[0019] Specifically, the communication module can adopt a Sub-G long-distance wireless communication module, access the wireless public communication network with the loraWAn protocol, and communicate with the background server.

[0020] Specifically, the Bluetooth positioning module and control module can use an MCU chip with integrated Bluetooth function. The Bluetooth protocol version used by the Bluetooth positioning module can be 5.0 or above. The Bluetooth positioning method can use any of RSSI, AoA / AoD or CS positioning methods. Of course, the use of Bluetooth positioning also requires the deployment of several Bluetooth beacons in the hospital. The Bluetooth positioning module receives the broadcast signal issued by the Bluetooth beacon and uses the built-in Bluetooth algorithm to calculate its own location based on the broadcast signal.

[0021] Specifically, the communication module sends the location information calculated by the Bluetooth positioning module to the background server, and the background server can pre-install an electronic map and connect a display device. The background server parses the location information into the electronic map and uses the display device to show the user the location of the mobile medical equipment on the map.

[0022] In the above embodiment, by detecting whether there is current in the power line of the mobile medical device, it can be determined whether the mobile medical device is connected to the mains or idle. When connected to the mains, since the mains is used for power supply, the power supply is sufficient, so the Bluetooth positioning module can perform real-time positioning for the mobile medical device, or can perform single positioning, and then enter sleep. The location information obtained by positioning can be displayed to the user through a display device. When the mobile medical device is not connected to the mains, or is in a power outage, the mobile medical device is not working at this time and is in an idle state. The gyroscope is used to determine whether the mobile medical device is moved to determine whether the positioning of the mobile medical device is real-time positioning or single positioning. When the device moves, in order to avoid the position of the device being difficult to find after it moves, the moving track of the mobile medical device can be left through real-time positioning, which is convenient for users to find. If the device does not move, the user can find it after a single positioning. Therefore, there is no need for real-time positioning. Entering sleep after positioning can reduce power consumption and extend the use time.

[0023] The above-mentioned embodiments are aimed at the problems that mobile medical equipment in hospitals is often used in different wards or departments, and it is still difficult to locate the position of mobile medical equipment by conventional manual recording of usage information, and the position of the equipment is forgotten after long-term non-use or power failure, or it is stolen after power failure. The mobile medical equipment positioning method can help users locate mobile medical equipment quickly and effectively, avoid the problem that the position of the equipment is difficult to find after it is forgotten, and provide the movement trajectory of the equipment to provide a tracing basis for finding it after it is powered off and moved.

[0024] In another embodiment, if there is no current in the power cord of the mobile medical device, the power management module also periodically detects the power in the backup battery. When the battery power is lower than the low power threshold, the control module controls the Bluetooth positioning module to perform a single positioning, and the communication module uploads the location information of the mobile medical device to the server, and then enters a low power consumption state. After the server obtains the location information of the mobile medical device, it displays the current location of the mobile medical device on the display device and issues a low power warning message.

[0025] Since the location of the mobile medical equipment has been forgotten and no one has used it for a long time, the backup battery may be exhausted. Therefore, in the above embodiment, by detecting the power of the backup battery, when it is lower than the low power threshold, it is automatically positioned once, and the positioning location information is sent to the server, so that when the user needs to use the mobile medical equipment, the server can also quickly find the location of the mobile medical equipment to avoid idle waste of the equipment. In addition, the display device connected to the server sends a low power alarm message of the mobile medical equipment, which can also prompt the user to go to the location as soon as possible to retrieve the mobile medical equipment and charge the backup battery.

[0026] In another embodiment, the mobile medical equipment positioning method further includes: When the battery power is lower than the low power threshold, an image of the mobile medical device is also obtained, the mobile medical device and multiple feature objects in the image are identified, and the positional relationship between the mobile medical device and the multiple feature objects is determined based on the pixel distances between the multiple feature objects and the mobile medical device, and the mobile medical device and the positional relationship are stored as an associated record.

[0027] Specifically, the characteristic objects may be patterns, logos and other fixed facilities in the hospital.

[0028] This embodiment further provides positioning when the battery is low. Images can be obtained through cameras installed in the hospital. If there is no camera at the relevant location, the image of the location that last appeared in the camera is obtained. After processing the image, the position relationship is obtained and stored. When the user searches for mobile medical equipment, prompts can be given according to the stored records.

[0029] In another embodiment, the mobile medical equipment positioning method further includes: The server obtains the mobile medical device usage demand information sent by the client, and sends a positioning instruction to the mobile medical device according to the usage demand of the mobile medical device. After the communication module of the mobile medical device receives the positioning instruction, the control module controls the Bluetooth positioning module to perform a single positioning, and the communication module uploads the location information of the mobile medical device to the server. The server compares the location information of the mobile medical device this time with the location information of the mobile medical device obtained last time. If the location information of the mobile medical device this time is different from the location information of the mobile medical device obtained last time, the location information of the mobile medical device this time will overwrite the location information of the mobile medical device obtained last time, and the location information of the mobile medical device this time will be fed back to the client; if the location information of the mobile medical device this time is the same as the location information of the mobile medical device obtained last time, the location information of the mobile medical device this time / or last time will be fed back to the client.

[0030] Specifically, a client that matches the server can also be set on the existing mobile terminal to obtain the user's usage requirement information for the mobile medical equipment. The client is connected to the server for communication. When the user enters the usage requirement information for the mobile medical equipment on the client, the server sends the location information of the mobile medical equipment it has saved to the client. An electronic map can also be pre-installed in the client, and the user can know the location of the mobile medical equipment by parsing the location information into the electronic map.

[0031] Specifically, the mobile terminal may be a smart phone, a laptop computer, or a smart wearable device, such as a smart watch or smart glasses, and the like.

[0032] In the above embodiment, the mobile medical device is positioned based on the user's usage needs. When the mobile medical device is not connected to the mains and there is no need to use it, as long as it is not in a mobile state or the backup battery is low on power, no positioning is performed. This can effectively reduce the power consumption of the backup battery and extend the use time of the backup battery. In addition, when the position of the mobile medical device changes, by comparing the location information of the current positioning with the location information of the previous positioning saved in the server, the location information of the previous positioning is covered and corrected, so that the location of the mobile medical device can be displayed to the user more accurately.

[0033] Based on the same inventive concept, the present invention also provides a mobile medical equipment positioning device, which is a device for implementing the above-mentioned mobile medical equipment positioning method.

[0034] See also Figure 2 As shown, the mobile medical equipment positioning device provided in the embodiment of the present application includes: A backup battery, a power management module, a gyroscope, a Bluetooth positioning module, a control module, and a communication module. The control module is signal-connected to the power management module, the gyroscope, the Bluetooth positioning module, and the communication module respectively. The backup battery is electrically connected to the power management module, the gyroscope, the Bluetooth positioning module, the control module, and the communication module respectively. The power management module is used to detect whether there is current in the power line of the mobile medical care device. If there is current in the power line of the mobile medical care device, the power management module uses the mains to power itself and the gyroscope, Bluetooth positioning module, and control module. If there is no current in the power line of the mobile medical care device, the power management module uses a backup battery to power itself and the gyroscope, Bluetooth positioning module, control module, and communication module. The control module is used to control the Bluetooth positioning module to perform positioning when there is current in the power line of the mobile medical device, and to periodically obtain the detection signal collected by the gyroscope when there is no current in the power line of the mobile medical device, and to determine whether the mobile medical device moves according to the detection signal. If the mobile medical device does not move, the control module controls the Bluetooth positioning module to perform single positioning, and if the mobile medical device moves, the control module controls the Bluetooth positioning module to perform real-time positioning; The backup battery is used to supply power to the power management module, the gyroscope, the Bluetooth positioning module, the control module, and the communication module when there is no current in the power line of the mobile medical device; The Bluetooth positioning module is used to locate the mobile medical device under the control of the control module; The gyroscope is used to collect motion information of the mobile medical equipment; The communication module is used to upload the location information of the mobile medical equipment to the server.

[0035] In another embodiment, if there is no current in the power cord of the mobile medical device, the power management module also periodically detects the power in the backup battery. When the battery power is lower than the low power threshold, the control module controls the Bluetooth positioning module to perform a single positioning, and the communication module uploads the location information of the mobile medical device to the server, and then enters a low power consumption state. After the server obtains the location information of the mobile medical device, it displays the current location of the mobile medical device on the display device and issues a low power warning message.

[0036] In another embodiment, after the communication module of the mobile medical device receives the positioning instruction, the control module controls the Bluetooth positioning module to perform a single positioning, and the communication module uploads the location information of the mobile medical device to the server. The positioning instruction is sent to the mobile medical device according to the usage requirements of the mobile medical device after the server obtains the usage requirement information of the mobile medical device sent by the client; the server compares the location information of the mobile medical device this time with the location information of the mobile medical device obtained last time. If the location information of the mobile medical device this time is different from the location information of the mobile medical device obtained last time, the location information of the mobile medical device this time will overwrite the location information of the mobile medical device obtained last time, and the location information of the mobile medical device this time will be fed back to the client; if the location information of the mobile medical device this time is the same as the location information of the mobile medical device obtained last time, the location information of the mobile medical device this time / or last time will be fed back to the client.

[0037] All relevant contents of each step involved in the embodiment of the mobile medical equipment positioning method described above can be referred to the functional description of the functional module corresponding to the mobile medical equipment positioning device in the embodiment of the present application, and will not be repeated here.

[0038] Although the aforementioned mobile medical equipment positioning device can locate the position of the mobile medical equipment under normal circumstances, there are still some extreme situations, such as when the backup battery is exhausted and the mobile medical equipment is moved again by someone, and it is also in a monitoring blind spot or power outage. At this time, it is difficult to track the position of the mobile medical equipment. In order to overcome this dilemma as much as possible, the following embodiment provides a possible solution.

[0039] like Figure 3 As shown, in another embodiment, the positioning device of the mobile medical care equipment 1 further comprises a tank car 2, and a vertical partition 3 is arranged in the tank car 2 to separate the tank car 2 into two areas, the mobile medical care equipment 1 is arranged in one of the areas, and a physical trace mechanism is arranged in the other area, and the physical trace mechanism comprises: A cylinder body 4 is vertically arranged with its opening facing downwards, a piston 5 is sealingly and slidably connected inside the cylinder body 4, and a connecting rod 6 is hingedly connected to the lower surface of the piston 5; A first gear 7 is vertically arranged below the cylinder body 4, an eccentric shaft is arranged on one side of the first gear 7, the lower end of the connecting rod 6 is hinged on the eccentric shaft, a horizontal wheel axle is arranged on the other side of the first gear 7, and a wheel axle height control component is arranged on the partition plate 3, the wheel axle of the first gear 7 is rotatably connected to the wheel axle height control component, so that the wheel axle height control component can control the wheel axle of the first gear 7 to move up and down; The second gear 8 is arranged on the wheel shaft of the tank car 2. A through hole is opened on the bottom plate of the tank car 2. When the axle of the first gear 7 is located at the lowest end of its stroke, the first gear 7 passes through the through hole and meshes with the second gear 8. The first gear 7, the connecting rod 6, the piston 5 and the cylinder body 4 constitute a crank connecting rod mechanism. When the axle of the first gear 7 is located at the highest end of its stroke, the first gear 7 is out of contact with the second gear 8. A solution tank 9 is provided above the cylinder body 4, a first liquid outlet is provided at the bottom of the solution tank 9, a liquid inlet is provided at the bottom of the cylinder body 4, the first liquid outlet is connected to the liquid inlet through a first pipe body, a first one-way valve 10 is provided at the liquid inlet which opens from the outside of the cylinder body 4 to the inside of the cylinder body 4, a second liquid outlet is also provided at the bottom of the cylinder body 4, a second one-way valve 11 is provided at the second liquid outlet which opens from the inside of the cylinder body 4 to the outside of the cylinder body 4, a liquid spray pipe 12 which is connected to the second liquid outlet is provided outside the cylinder body 4, the liquid spray pipe 12 passes through the side wall of the tank car 2 and extends to the outside of the tank car 2, and a nozzle 13 is provided at the free end of the liquid spray pipe 12; The wheel axle height control component is electrically connected to the backup battery. When the backup battery is powered, the wheel axle height control component lifts the wheel axle of the first gear 7 to the highest end of the travel. When the backup battery is powered off, the first gear 7 and its wheel axle fall to the lowest end of the travel under the action of gravity. The space between the cylinder 4 and the piston 5 is filled with fluorescent tracer liquid, and the solution tank 9 is also provided with the fluorescent tracer liquid.

[0040] In the above embodiment, when the backup battery has power, the axle height control component lifts the axle of the first gear 7 to the highest end of the stroke. At this time, the first gear 7 is separated from the second gear 8. When someone pushes the tank truck 2 carrying the mobile medical equipment 1 to move, it can be located through the Bluetooth positioning module. When the backup battery is out of power, the first gear 7 and its axle fall to the lowest end of the stroke under the action of gravity, and the first gear 7 is meshed with the second gear 8. When someone pushes the tank truck 2 carrying the mobile medical equipment 1 to move, the wheel of the tank truck 2 drives the axle to rotate, and the second gear 8 rotates together with the wheel axle, and the second gear 8 can drive the first gear 7 to rotate. The first gear 7, the connecting rod 6, the piston 5 and the cylinder body 4 constitute a crank connecting rod 6 mechanism. When the first gear 7 rotates, it drives the piston 5 to move upward, the volume of the cylinder body 4 decreases, the pressure increases, the first one-way valve 10 is closed, and the second one-way valve 11 is opened. The fluorescent tracer liquid in the cylinder body 4 is sprayed from the second liquid outlet along the spray pipe 12 and the nozzle 13 to the way. In this way, the user can search along the fluorescent tracer liquid from the position where the Bluetooth positioning module was last positioned, which can help the user find the mobile medical equipment 1 that is moved again by someone as soon as possible after the backup battery is exhausted. Then, as the first gear 7 continues to rotate, the piston 5 moves downward, the volume of the cylinder 4 increases, the pressure decreases, the first one-way valve 10 opens, the second one-way valve 11 closes, and the fluorescent tracer liquid in the solution tank 9 is replenished into the cylinder 4 from the first liquid outlet along the first tube.

[0041] It is not difficult to see from the usage process of the above embodiment that when the mobile medical device 1 is moved again after the backup battery is exhausted, the physical trace mechanism can continue to spray the fluorescent tracer liquid along the moving route of the mobile medical device 1 for tracking, thereby helping the user to find the mobile medical device 1 that has been moved again as soon as possible.

[0042] Specifically, the axle height control assembly includes: A slider 14, wherein the partition plate 3 is provided with a slide groove matching the slider 14; The electromagnet 15 is arranged on the partition 3 and above the slider 14. The top of the slider 14 is provided with an armature for driving the slider 14 to move upward under the adsorption of the electromagnet 15. The axle of the first gear 7 is rotatably connected to the side wall of the slider 14, and the electromagnet 15 is electrically connected to the backup battery so as to adsorb the armature when the backup battery has power.

[0043] In the above embodiment, when the backup battery is powered, the electromagnet 15 attracts the armature on the top of the slider 14, causing the slider 14 to move upward, thereby causing the first gear 7 to disengage from the second gear 8. When the backup battery is out of power, the electromagnet 15 cannot attract the slider 14, and the slider 14 falls to the lowest end of the stroke due to the gravity of itself, the first gear 7 and its axle. At this time, the first gear 7 is meshed with the second gear 8, and the second gear 8 can transmit power to the first gear 7.

[0044] It is not difficult to see from the use process of the above embodiment that based on the power of the backup battery, the physical tracer mechanism can be effectively controlled to start working when there is no electricity, thereby avoiding the fluorescent tracer liquid from being consumed and wasted when there is electricity.

[0045] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
