[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Figure 1 A schematic diagram showing a portable medical device provided by an embodiment of the present invention, as Figure 1 shown, the present application provides a portable medical device, including a housing 10 (not shown in the figure), a mounting plate 20, an image processing module 21, a power management module 22, a data acquisition module 23, a screen module connection module 24, and a display module 26 (not shown in the figure).

[0031] Among them, the outer shell 10 has a receiving cavity 101 (not shown in the figure); the mounting plate 20 is arranged in the receiving cavity 101, and an image processing module 21, a power management module 22, a data acquisition module 23, and a screen module connection module 24 are arranged on the mounting plate 20. The image processing module 21 is electrically connected to the power management module 22, the data acquisition module 23, and the screen module connection module 24 respectively. Among them, the data acquisition module 23 is at least used to connect to an endoscope and acquire the image information of the endoscope, and the image processing module 21 is at least used to process the image information acquired by the data acquisition module 23 and transmit the signal to the screen module connection module 24. The power management module 22 is connected to a pluggable power adapter, a battery pack unit, and the main control unit of the portable medical device. The power adapter is used to connect to an AC power supply and supply power to the load of the portable medical device and / or charge the battery pack unit under the control of the power management module 22. The battery pack unit is used to supply power to the portable medical device under the control of the power management module 22. The main control unit and the power management module 22 are respectively used for thermal management of the portable medical device.

[0032] The display module 26 is arranged on the outer shell 10 to seal the receiving cavity 101. The display module 26 is electrically connected to the screen module connection module 24 to display the signal transmitted by the screen module connection module 24.

[0033] In this embodiment, the display module 26 can be a display screen. When actually processing the endoscope system, the image processing module 21, the power management module 22, the data acquisition module 23, and the screen module connection module 24 can all be arranged on the mounting plate 20, and then the mounting plate 20 is arranged in the receiving cavity 101, and then the display module 26 is installed on the outer shell 10 to seal the receiving cavity 101.

Such a setting can not only reduce the occupied volume of each module in the receiving cavity 101, thereby reducing the overall weight of the endoscope system and facilitating the miniaturization design of the endoscope system, but also simplifies the traditional endoscope image processing device, combines the image processing function and the image display function into one, is convenient for carrying and transferring, so that it does not need to rely on traditional monitoring instrument equipment, greatly expanding the use range and scenarios of the endoscope system in this embodiment, and even extending the inspection scenario of the endoscope system from within the hospital to out-of-hospital first aid and other scenarios.

[0034] In some embodiments, a key light-emitting module 25 may also be provided on the mounting plate 20. The key light-emitting module 25 is at least used to control the start and stop of the endoscope system through the image processing module 21 and indicate the working state of the endoscope system.

[0035] Figure 2 Another schematic diagram of the portable medical device provided by the embodiment of the present invention is shown, as Figure 2 shown, the power management module 22 is connected to the pluggable power adapter 12, the battery pack unit 13, and the main control unit 14 of the portable medical device.

[0036] Among them, the power adapter 13 is used to connect to an AC power supply, and under the control of the power management module 22, it supplies power to the electrical load 2 of the portable medical device and / or charges the battery pack unit 13. The battery pack unit 13 is used to supply power to the portable medical device under the control of the power management module 22. The main control unit 14 and the power management module 22 are respectively used for thermal management of the portable medical device. The electrical load 2 of the portable medical device may include an image processing module 21, a data acquisition module 23, a screen module connection module 24, and a display module 26.

[0037] In some possible implementation manners, the power management module 22 may control to directly supply power to the portable medical device using an AC power supply, or may control to charge the battery pack unit 13 using an AC power supply, or may also control to charge the battery pack unit 13 while directly supplying power to the portable medical device using an AC power supply.

[0038] In the case where it is inconvenient to connect to an AC power supply through the power adapter, the power management module 22 may control the battery pack unit 13 to supply power to the portable medical device, so that the portable medical device can be used without an AC power supply, expanding the application scenarios of the portable medical device.

[0039] In some embodiments, the power management module 22 has sensors. The main control unit 14 may be disposed on one side in the length or width direction of the battery pack unit, and the power management module 22 may be disposed on one side in the thickness direction of the battery pack unit. The main control unit 14 may be communicatively connected to the power management module 22.

[0040] In some embodiments, the sensors may be one or more temperature sensors disposed at the electrical load 2. The main control unit 14 may turn on / off the preset functions / algorithms of the portable medical device according to the detection data of the sensors (such as the load temperature), thereby reducing the heat generation of the electrical load.

[0041] The power management module 22 can control the turning on / off of the fan in the portable medical device according to the detection data of the sensor (such as the load temperature), and / or adjust the brightness of the display screen, so as to control heat dissipation in a timely manner and / or reduce the heat generation of the display screen. In some embodiments, the power management module 22 can also control the rotation speed of the fan in the portable medical device according to the detection data of the sensor (such as the load temperature).

[0042] In some embodiments, the power management module 22 can also obtain the temperature parameter of the battery pack in the battery pack unit by communicating with the battery pack unit 13. The main control unit 14 can obtain the temperature parameter of the battery pack unit 13 through the power management module 22. The main control unit 14 and the power management module 22 can obtain the system temperature by performing weighted processing on the temperature parameter of the battery pack and the detection data of the sensor (such as the load temperature). The power management module 22 and the main control unit 14 can adopt the following technical solutions to perform thermal management on the electrical load 2:

[0043] The power management module 22 can turn on the fan to strengthen heat convection and system heat dissipation when the system temperature is greater than or equal to the first temperature threshold;

[0044] The power management module 22 can reduce the brightness of the display screen of the portable medical endoscope to reduce heat generation when the system temperature is greater than or equal to the second temperature threshold and the duration reaches the first time threshold;

[0045] The main control unit 14 can disable the optional video recording function of the portable medical endoscope to reduce heat generation when the system temperature is greater than or equal to the second temperature threshold and the duration reaches the first time threshold;

[0046] The main control unit 14 can disable the optional intelligent algorithm of the portable medical endoscope to reduce heat generation when the system temperature is greater than or equal to the second temperature threshold and the duration reaches the first time threshold.

[0047] In some possible implementation manners, the main control unit 14 can be a microcontroller. For example, it can be the microcontroller GD32F303RET6. The above thermal management functions can be implemented by software programming the microcontroller in combination with related technologies.

[0048] By adopting the above technical solutions, the portable medical device can be used without an AC power supply by using the battery pack unit for power supply, and the portable medical device can still meet the needs of emergency diagnosis and treatment even in a harsh high-temperature environment, avoiding the occurrence of medical accidents and improving the experience of medical staff and patients.

[0049] In some embodiments, the battery pack unit 13 includes a battery pack that is replaceably disposed in a portable medical device. The battery cells of the battery pack are ordinary lithium-ion polymer battery cells or special polymer battery cells. Exemplarily, the special polymer battery cell can be a lithium titanate special polymer battery cell.

[0050] When the battery cells of the battery pack are special polymer battery cells, the battery pack in the portable medical device can be adapted to a natural environment with a lower temperature. For example, when the battery cells of the battery pack are ordinary lithium-ion polymer battery cells, the temperature threshold for battery overcooling prompt can be 5°C, while when the battery cells of the battery pack are special polymer battery cells, the temperature threshold for battery overcooling prompt can be -20°C.

[0051] By adopting the above technical solution, through the battery pack that is replaceably disposed in the portable medical device, the battery pack in the portable medical device can be replaced with a battery pack using special polymer battery cells in an alpine environment, so that the portable medical device can still meet the needs of emergency diagnosis and treatment even in a harsh alpine environment, avoid the occurrence of medical accidents, and improve the experience of medical staff and patients.

[0052] In some embodiments, heat insulation pads are provided between the battery pack and the power management module 22, the main control unit 14, the data acquisition module 23, and the screen module connection module 24. Heat insulation pads are also provided between multiple battery packs or between multiple battery cells in a single battery pack. The battery pack is also connected to the housing 10 of the portable medical device through a heat conduction pad.

[0053] Specifically, the battery pack unit 14 can include three groups of series-connected battery packs with a standard voltage of 10.9V. Each battery pack can be composed of three lithium batteries connected in parallel. Heat insulation pads can be provided between the battery pack and the power management module 22, the main control unit 14, the data acquisition module 23, and the screen module connection module 24. Heat insulation pads can also be provided between multiple battery packs and between multiple batteries in the battery pack. Heat insulation pads can also be provided between the battery pack and other components in the battery pack unit 13 to facilitate heat transfer isolation. The battery pack can also be connected to the housing 10 of the portable medical device through a heat conduction pad to conduct heat to the housing 10 in a timely manner. In some embodiments, the housing 10 can be a metal housing that facilitates heat dissipation.

[0054] The above heat insulation pads can be made of general heat insulation materials in related technologies, and the above heat conduction pads can be made of general heat conduction materials in related technologies.

[0055] By adopting the above technical solution, the heat dissipation capacity and heat insulation capacity of the battery pack unit 13 can be improved, thereby further enhancing the adaptability of the portable medical device to a harsh high-temperature environment.

[0056] Figure 3Another schematic diagram showing the portable medical device provided by the embodiment of the present invention is as follows Figure 3 As shown, the battery pack unit 13 includes a battery pack 131, a collection and monitoring circuit 132, and a control switch 133. Among them, the collection and monitoring circuit 132, the control switch 133, and the battery pack 131 in the battery pack unit are connected pairwise. The collection and monitoring circuit 132 is connected to the power management module 22 through the first communication interface 135, and the control switch 133 is connected to the power management module 22 through the power interface 134. The collection and monitoring circuit 132 is used to collect the temperature parameters of the battery pack 131, and the control switch 133 controls the charging and discharging of the battery pack 131 based on the temperature parameters.

[0057] In some possible implementation manners, the control switch 133 may be a switching MOS (Metal Oxide Semiconductor Field Effect Transistor).

[0058] The collection and monitoring circuit 132 may be implemented based on an overcharge and over-discharge protection chip. Specifically, the following method may be adopted to control the charging and discharging of the battery pack through the control switch 133 based on the temperature parameters:

[0059] When the battery temperature is greater than the third temperature threshold, the control switch may be turned off, and the battery pack 131 is not allowed to discharge;

[0060] When the battery temperature is greater than the fourth temperature threshold, the control switch may be turned off, and the battery pack 131 is not allowed to charge;

[0061] When the battery temperature is less than the fifth temperature threshold, the control switch may be turned off, and the battery pack 131 is not allowed to charge;

[0062] When the battery temperature is less than the sixth temperature threshold, the control switch may be turned off, and the battery pack 131 is not allowed to discharge.

[0063] Among them, the third temperature threshold may be 65±5°C, the fourth temperature threshold may be 55±5°C. When the battery cell of the battery pack is a common lithium-ion polymer battery cell, the fifth temperature threshold may be 0±5°C, and the sixth temperature threshold may be -20±5°C. When the battery cell of the battery pack is a special polymer battery cell, the fifth temperature threshold may be -25±5°C, and the sixth temperature threshold may be -30±5°C.

[0064] By adopting the above technical solution, through the charging and discharging protection in high-temperature or high-cold environments, the portable medical device can still meet the needs of emergency diagnosis and treatment even in harsh high-temperature or high-cold environments, avoid the occurrence of medical accidents, and improve the experience of medical staff and patients.

[0065] In some embodiments, the acquisition and monitoring circuit 132 is further configured to acquire the current parameter of the battery pack 131, and the control switch disconnects the charging current input, disconnects the discharging current output, resumes the charging current input, or resumes the discharging current output based on the current parameter.

[0066] In some possible implementation manners, the acquisition and monitoring circuit 132 may use an overcharge and over-discharge chip to disconnect the charging current input or the discharging current output, or resume the charging current input or the discharging current output based on the current parameter through the control switch.

[0067] In some possible implementation manners, the acquisition and monitoring circuit 132 may acquire the current parameter of the battery pack 131 through a high-precision ADC (Analog-to-Digital Converter) and a current detection circuit in related technologies. When the battery pack 131 is charging and the detected current parameter is greater than the first current threshold, the acquisition and monitoring circuit 132 may automatically disconnect the charging current input. When the battery pack 131 is discharging and the detected current parameter is greater than the second current threshold, the acquisition and monitoring circuit 132 may automatically disconnect the discharging current output. When the charge and discharge state of the battery pack 131 is reversed (for example, changed from the charging input state to the discharging output state), the charging current input or the discharging current output is automatically resumed.

[0068] In another possible implementation manner, a secondary protection circuit in related technologies may be used for further overcurrent protection. When the battery pack 131 is charging and the detected current parameter is greater than the third current threshold, the acquisition and monitoring circuit 132 may automatically disconnect the charging current input. When the battery pack 131 is discharging and the detected current parameter is greater than the fourth current threshold, the acquisition and monitoring circuit 132 may automatically disconnect the discharging current output. When the charge and discharge state of the battery pack 131 is reversed (for example, changed from the charging input state to the discharging output state), the charging current input or the discharging current output is automatically resumed. Herein, the third current threshold is greater than the first current threshold, and the fourth current threshold is greater than the second current threshold.

[0069] By adopting the above technical solution, overcurrent protection can be provided for the charge and discharge of the battery pack, thereby improving the safety of the charge and discharge of the battery pack unit and protecting the safety of the portable medical device.

[0070] In some embodiments, the power management module 22 includes a power circuit for controlling charging of the battery pack unit or powering the portable medical device through the battery pack unit. The power circuit is connected to a pluggable power adapter through a main power interface, the power circuit is connected to a control switch 133 through a battery power interface, and the power circuit is connected to an image processing module 21, a data acquisition module 23, a screen module connection module 24, and a display module 26 through a load power supply interface for powering the image processing module 21, the data acquisition module 23, the screen module connection module 24, and the display module 26. A one-time fuse is provided in the power circuit.

[0071] The one-time fuse is used for overcurrent protection failure, and automatically disconnects the electrical connection between the battery and other components when the charging and discharging current is too large for a long time.

[0072] With the above technical solution, by providing the one-time fuse in the power circuit, the safety of the portable medical device can be further protected in case of abnormal overcurrent protection.

[0073] In some embodiments, the power circuit further includes an internal digital sampling monitor for collecting the first voltage parameter of a single battery or the battery pack in the battery pack, and automatically disconnecting the charging current input or the discharging current output based on the first voltage parameter. In some possible implementation manners, the internal digital sampling monitor can be implemented by an ADC in related technologies, for example, it can be implemented by SC8886.

[0074] The first voltage parameter may include the overall voltage of the battery pack and / or the voltage of a single battery. The internal digital sampling monitor can automatically disconnect the charging current input when detecting that the overall voltage of the battery pack is greater than the first voltage threshold, and automatically disconnect the discharging current output when detecting that the voltage of any single battery in the battery pack 131 is less than the second voltage threshold.

[0075] In some embodiments, Figure 3 the acquisition and monitoring circuit 132 in

[0076] The second voltage parameter may include the overall voltage of the battery pack and / or the voltage of a single battery cell. The acquisition and monitoring circuit 132 can detect the voltage of a single battery cell through an ADC. When the voltage of any single battery cell in the battery pack 131 is detected to be greater than the third voltage threshold, the charging current input is disconnected. When the voltage of any single battery cell in the battery pack 131 is detected to be less than the fourth voltage threshold, the discharge current output is disconnected. The acquisition and monitoring circuit 132 can also detect the overall voltage of the battery pack through a secondary protection circuit. When the overall voltage of the battery pack is detected to be greater than the fifth voltage threshold, the charging current input is disconnected. When the overall voltage of the battery pack is detected to be less than the sixth voltage threshold, the discharge current output is disconnected.

[0077] The above first voltage threshold to sixth voltage threshold can be set reasonably and flexibly based on the actual situation.

[0078] Adopting the above technical solution can provide overvoltage protection for the charging and discharging of the battery pack, thereby improving the safety of the charging and discharging of the battery pack unit and protecting the safety of the portable medical device.

[0079] In some embodiments, the power management module 22 includes a numerically controlled power management circuit. The numerically controlled power management circuit is connected to the acquisition and monitoring circuit through a battery communication interface, and the numerically controlled power management circuit is connected to the main control unit through a load communication interface. The numerically controlled power management circuit is used to communicate with the acquisition and monitoring circuit to obtain temperature parameters, and based on the temperature parameters, prompt information to the main control unit, so that the main control unit controls the portable medical device to shut down after displaying an overheat prompt, an overcool prompt or a shutdown prompt through the display module 26.

[0080] Figure 4 Another schematic diagram of the portable medical device provided by the embodiment of the present invention is shown, as Figure 4 shown, the power management module 22 includes a power circuit 221 and a numerically controlled power management circuit 222. Among them, the power circuit 221 is connected to the power adapter 12 through the main power interface 223, and uses the AC power connected by the power adapter 12 as the main power. The power circuit 221 is connected to the power interface 134 of the battery pack unit 13 through the battery power interface 224 to control the charging of the battery pack 131 or to supply power using the battery pack 131. The power circuit 221 is also connected to the image processing module 21, the data acquisition module 23, the screen module connection module 24 and the display module 26 through the load power supply interface 226 to supply power to the image processing module 21, the data acquisition module 23, the screen module connection module 24 and the display module 26.

[0081] The numerically controlled power management circuit 222 is used to communicate with the acquisition and monitoring circuit 132, obtain temperature parameters, and prompt the main control unit based on the temperature parameters, so that the main control unit controls the portable medical device to shut down after displaying an overheat prompt, an overcool prompt, or a shutdown prompt through the display module 26. Specifically, the numerically controlled power management circuit 222 can be connected to the first communication interface 135 of the battery pack unit through the battery communication interface 225, and the numerically controlled power management circuit 222 is also connected to the main control unit 14 through the load communication interface 227.

[0082] In some possible implementation manners, the numerically controlled power management circuit 222 can be implemented by programming a microcontroller (such as MP2760) in related technologies.

[0083] The numerically controlled power management circuit 222 sends prompt information to the main control unit based on the temperature parameters in the following manner, so that the main control unit controls the portable medical device to shut down after displaying an overheat prompt, an overcool prompt, or a shutdown prompt through the display module 26.

[0084] The numerically controlled power management circuit 222 can send a shutdown prompt and actively shut down after waiting for a preset time when the battery cells of the battery pack are ordinary lithium-ion polymer cells, the temperature parameter is less than the seventh temperature threshold, and the power management module 22 is not connected to an AC power supply, so as to enable medical staff to make preparations for ending the diagnosis and treatment in advance.
