The term "module" used in the present application may be an integrated chip having a certain function, or may be a general circuit composed of circuit components, or in other forms. In order to make the technical solutions provided by the embodiments of the present invention clearer, the above solutions are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 and fig. 2 together, fig. 1 is a schematic structural diagram of a medical apparatus according to a first embodiment of the present invention; fig. 2 is a schematic diagram illustrating a connection relationship between a battery management module and a battery in a battery pack in the medical device provided in fig. 1. The medical device 1 includes a detection module 100, an rescue module 200, a battery pack 300, and a battery management module 400. The battery pack 300 includes a plurality of batteries 310, the detection module 100 is used to detect a target object, and the rescue module 200 is used to rescue the target object. The battery management module 400 is used for identifying information of each battery 310 in the battery pack 300, and supplying power to the detection module 100 by adopting a first power supply strategy according to the information of each battery 310, and supplying power to the treatment module 200 by adopting a second power supply strategy according to the information of each battery 310.

The medical apparatus 1 is an important medical device for rescuing patients, and plays an important role in rescuing patients if each component in the medical apparatus 1 can work normally. The medical device 1 of the present application includes the battery pack 300, the battery pack 300 includes a plurality of batteries 310, and when one of the batteries 310 is dead, the other batteries 310 in the battery pack 300 can continue to function to supply power to the detection module 100 and the treatment module 200, thereby ensuring the electric energy required for normal operation in the medical device 1.

Specifically, the battery management module 400 is electrically connected to each of the batteries 310 through the communication line 510, respectively, and reads information of the batteries 310 through the communication line 510, wherein the information of the batteries 310 includes the voltage and the capacity of the batteries 310.

Further, the battery management module 400 is electrically connected to each battery 310 through a wire 530 and a switch 540. When the battery management module 400 controls the corresponding switch 540 to be closed, the battery 310 provides power to the detection module 100 or the rescue module 200; when the battery management module 400 controls the corresponding switch 540 to be turned off, the battery 310 does not provide power to the detection module 100 and the rescue module 200.

In one embodiment, the battery management module 400 is configured to select the battery 310 with the largest capacity to supply power to the detection module 100.

In one embodiment, the battery management module 400 is configured to select all of the batteries 310 in the battery pack 300 to power the rescue module 200.

Generally speaking, the power consumed by the detection module 100 when detecting the target patient is less than the power consumed by the treatment module 200 when treating the target patient, the battery management module 400 selects the battery 310 with the largest capacitance to supply power to the detection module 100, so as to ensure the power required by the detection module 100, and the battery management module 400 selects all the batteries 310 to supply power to the treatment module 200, so as to ensure that the treatment module 200 has sufficient power in the process of treating the target patient, so as to avoid the working failure of the treatment module 200 in the process of treating due to the insufficient capacitance of the batteries 310.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a medical apparatus according to a second embodiment of the present invention. The connection relationship between the battery management module 400 in the medical device 1 of the present embodiment and the battery 310 in the battery pack 300 is the same as the connection relationship between the battery management module 400 in the medical device 1 and the battery 310 in the battery pack 300 provided in the first embodiment of the present invention. The medical apparatus 1 in the present embodiment is basically the same as the medical apparatus 1 provided in the first embodiment, except that in the present embodiment, the medical apparatus 1 further includes a processor 600. When the detection module 100 does not operate within the past preset time period, the processor 600 controls the battery management module 400 to select the preset battery 310 in the battery pack 300 to supply power to the detection module 100 by using the first power supply strategy.

Further, when the detection module 100 operates within the past preset time period, the processor 600 selects at least one battery 310 as a target power supply battery according to the average power consumption of the detection module 100 within the past preset time period, where the target power supply battery is used for supplying power to the detection module 100, and a total capacity of the target power supply battery is greater than or equal to the average power consumption.

For example, the past preset time period may be, but is not limited to, a past month. When the detection module 100 is not operated within the past preset time period, the processor 600 controls the battery management module 400 to select the preset battery 310 in the battery pack 300 to supply power to the detection module 100. The predetermined battery 310 may be the battery 310 with the largest capacitance in the battery pack 300, or may be the battery 310 with a capacitance larger than a predetermined capacitance in the battery pack 300. When the detection module 100 operates within the past preset time period, the processor 600 records the power consumed by the detection module 100 during each operation within the past preset time period, and calculates the average power consumption of the detection module 100 during the past preset time period according to the power consumed by the detection module 100 during each operation within the past preset time period and the number of times the detection module 100 operates within the past preset time period.

Generally, the detection module 100 requires at least a first preset time for completing the whole detection process each time. When the time of each work of the detection module 100 is less than the first preset time, the detection module 100 is considered not to complete the whole detection process; when the time of each operation of the detection module 100 is greater than or equal to the first preset time, the detection module 100 is considered to complete the whole detection process. The first preset time may be, but is not limited to, 15 seconds. Since the detection module 100 does not complete the entire detection process when the working time of the detection module 100 is less than the first preset time within the past preset time period, the work of the detection module 100 is regarded as an invalid work each time the working time is less than the first preset time. When the operation time of the detection module 100 is greater than or equal to the first preset time within the past preset time period, the detection module 100 completes the entire detection process, and thus, the operation of the detection module 100 is regarded as one effective operation each time the operation takes time to be greater than or equal to the first preset time. Further, the processor 600 calculates the average power consumption of the detection module 100 in the past preset time period according to the power consumed by each effective operation of the detection module 100 in the past preset time period and the number of times that the detection module 100 is effectively operated in the past preset time period. Specifically, the average power consumption of the detection module 100 in the past preset time period is equal to the sum of the power consumed by the effective operation of the detection module 100 in the past preset time period divided by the total number of effective operations of the detection module 100 in the past preset time period.

In the embodiment, each time the detection module 100 works, the effective work and the ineffective work are distinguished, so that the accuracy of calculating the average power consumption of the detection module 100 in the past preset time period is improved.

Further, the processor 600 is also used for monitoring the operation progress of the detection module 100 and obtaining the current capacity remaining in the target power supply battery through the battery management module 400. The processor 600 is further configured to control the battery management module 400 to add a new battery 310 to the target power supply battery when the remaining capacity of the current target power supply battery is not enough to support the whole operation process of the detection module 100.

Specifically, although the total capacity of the target battery 310 is selected to be greater than or equal to the average power consumption, since the situation may be different each time the medical device 1 is used to perform emergency treatment on the target patient, there may be a case where the total capacity of the target battery 310 is insufficient to support the entire operation process of the detection module 100. When the remaining capacity of the current target power supply battery is not enough to support the whole operation process of the detection module 100, the processor 600 controls the battery management module 400 to add a new battery 310 to the target power supply battery, so that the detection module 100 has enough power to complete the whole detection operation.

Further, when the remaining capacity of the current target power supply battery is greater than or equal to the threshold capacity, the processor 600 monitors the operation progress of the detection module 100 at a first detection frequency; when the current capacity of the target power supply battery is smaller than the threshold capacity, the processor 600 monitors the operation progress of the detection module 100 at a second detection frequency, wherein the second detection frequency is greater than the first detection frequency. When the remaining capacity of the target power supply battery is greater than or equal to the threshold capacity, it indicates that the capacity of the target power supply battery is sufficient, and at this time, the processor 600 monitors the operation progress of the detection module 100 at a slower frequency. When the remaining capacity of the current target power supply battery is smaller than the threshold capacity, it indicates that the target power supply battery is insufficient, and at this time, the processor 600 monitors the operation schedule of the detection module 100 at a relatively frequent monitoring frequency, so as to add a new battery 310 to the target power supply battery in time when the operation schedule of the detection module 100 is not completed and the target power supply battery is insufficient.

Further, the medical device 1 further includes a processor 600, and when the rescue module 200 does not operate within the past preset time, the processor 600 controls the battery management module 400 to select the preset battery 310 in the battery pack 300 to supply power to the rescue module 200 using the second power supply strategy.

For example, the preset segment in the past may be, but is not limited to, a month in the past. When the rescue module 200 does not work within a preset time period, the processor 600 controls the battery management module 400 to select all the batteries 310 in the battery pack 300 to supply power to the rescue module 200, or the processor 600 controls several batteries 310 in the battery management module 400 to supply power to the rescue module 200.

Further, when the rescue module 200 operates within the past preset time period, the processor 600 selects at least one battery 310 as a target power supply battery for supplying power to the rescue module 200 according to the maximum power consumption of the rescue module 200 within the past preset time period and the capacitance of each battery 310, wherein the total capacitance of the target power supply batteries is greater than or equal to the maximum power consumption of the rescue module 200.

The treatment module 200 generally requires sufficient power to treat the target patient, and if the power is insufficient, the treatment of the target patient cannot be completed. Therefore, the processor 600 selects the battery 310 as the target power supply battery according to the maximum power consumption of the rescue module 200 and the capacity of each battery 310 in the past preset time period.

Further, when the capacities of the plurality of batteries 310 all satisfy the condition of being selected as the target power supply battery, the processor 600 selects the target power supply battery according to the voltage value of each battery 310, wherein when the difference of the capacities of the batteries 310 is within the preset difference range, the voltage of the battery 310 selected as the target power supply battery is greater than the voltage of the battery 310 not selected as the target battery 310.

For example, when the first battery and the second battery in the battery pack 300 have the same capacitance, the voltage value of the first battery is greater than the voltage value of the second battery. Since the voltage value of the first battery is greater than that of the second battery, the time taken for the first battery to charge the functional module (e.g., the rescue module 200) in the medical device 1 to the preset electric quantity is short. The above description is made by taking the example that the two batteries in the battery pack 300 have the same capacitance but different voltage values. It is understood that when the difference between the capacities of the two batteries in the battery pack 300 is small (smaller than the preset capacity difference), but the difference between the voltages is large (greater than or equal to the preset voltage difference), the battery 310 with the larger voltage is selected as the target power supply battery, so that the time taken to charge the functional module in the medical device 1 to the preset capacity is short.

The medical device 1 may be, but is not limited to being, a defibrillator, and the medical device 1 will be described in detail below in connection with the medical device 1 described in the foregoing embodiments. Referring to fig. 4, fig. 4 is a schematic structural diagram of a defibrillator according to a first embodiment of the present application. The defibrillator includes a pair of electrode pads 700, and the detection module 100 includes an impedance detection module 110 and an electrocardiogram sensing module 120. The impedance detection module 110 and the electrocardiogram sensing module 120 are connected to the electrode sheet 700, when the electrode sheet 700 is adhered to the target object, the impedance detection module 110 receives the electric energy provided by the target battery to detect the impedance value between the pair of electrode sheets 700, and the electrocardiogram sensing module 120 receives the electric energy provided by the target battery to sense the electrocardiogram signal of the target object.

When the defibrillator is in operation, the pair of electrode pads 700 are adhered to the subject, for example, but not limited to, the chest of the subject, to which the pair of electrode pads 700 are adhered. The impedance detection module 110 receives the power supplied by the target power supply battery and operates under the driving of the power supplied by the target power supply battery. The impedance detection module 110 detects an impedance value between the pair of electrode sheets 700, and determines whether the pair of electrode sheets 700 are normally bonded when being bonded to the target object according to the detected impedance value. When the impedance detection module 110 detects that the impedance value between the pair of electrode plates 700 is within the preset impedance value range, it is determined that the pair of electrode plates 700 are normally bonded to the target object. Generally, the predetermined impedance value range is greater than or equal to 100 ohms and less than or equal to 500 ohms. When the impedance value between the pair of electrode sheets 700 is greater than the maximum value in the preset impedance value range, it indicates that the electrode sheets 700 are poorly bonded with the target object; when the impedance value between the pair of electrode sheets 700 is smaller than the minimum value in the preset impedance value range, it indicates that the bonding position between the pair of electrode sheets 700 is too close. The ecg sensing module 120 receives the power supplied from the target battery and operates under the power supplied from the target battery. When the pair of electrode pads 700 is attached to the target subject, the ECG sensing module 120 senses the heart activity of the target subject through the pair of electrode pads 700 to obtain a corresponding ECG (electrocardiogram) signal. The defibrillator also includes a processor 600, and the processor 600 analyzes the electrocardiogram signals to determine whether the target subject meets the shock condition. For example, when it is determined from the ECG signal that the heart rhythm of the target subject includes at least one of ventricular fibrillation, ventricular tachycardia and ventricular flutter, it may be determined that the target subject satisfies the shock condition. When the heart rhythm of the target subject is judged to be any one of bradycardia, electromechanical separation, ventricular spontaneous rhythm and normal rhythm according to the ECG signal, it can be judged that the target subject does not satisfy the electric shock condition.

Referring to fig. 5 and 6 together, fig. 5 is a schematic structural diagram of an impedance detection module in the defibrillator shown in fig. 4; fig. 6 is a schematic diagram of an equivalent circuit for operation of the defibrillator shown in fig. 5. The impedance detection module 110 includes a signal generation module 111, a signal detection module 112, and a sampling module 113. The signal generating module 111 is used for generating a detection signal, and the detection signal is loaded on the target object through a pair of electrode plates 700. For convenience of description, the pair of electrode sheets 700 are named a first electrode sheet and a second electrode sheet, respectively. The equivalent impedance of the first electrode plate is Z1, the equivalent impedance of the second electrode plate is Z2, and the equivalent impedance between the first electrode plate and the second electrode plate is Z3. A complete loop is formed among the signal generating module 111, the first electrode sheet, the target object, and the second electrode sheet. The signal detection modules 112 are respectively connected to a pair of electrode plates 700, that is, one end of the signal detection module 112 is connected to the first electrode plate, and the other end is connected to the second electrode plate. When the detection signal is loaded onto the target object through the pair of electrode pads 700, the signal detection module 112 detects the detection signal loaded onto the target object to obtain a first signal, and the sampling module 113 is configured to sample the first signal to convert the first signal into a second signal, where the first signal is an analog signal and the second signal is a digital signal. The processor 600 is configured to obtain an impedance value between the pair of electrode sheets 700 according to the second signal, so as to determine whether the pair of electrode sheets 700 is correctly adhered to the target object. In this embodiment, the sampling module 113 samples a first signal, which is an analog signal, to obtain a second signal, which is a digital signal, so as to facilitate processing and operation by the processor 600.

Further, the impedance detection module 110 further includes an amplification module 114, and the amplification module 114 is configured to amplify the second signal. At this time, the processor 600 is configured to obtain an impedance value between the pair of electrode pads 700 according to the amplified second signal. In this embodiment, the second signal is amplified to improve the accuracy of the obtained impedance value between the pair of electrode sheets 700.

Referring to fig. 7, fig. 7 is a schematic diagram illustrating a structure of a treatment module in the defibrillator shown in fig. 4. The medical device 1 is a defibrillator, which includes a pair of electrode pads 700, and the treatment module 200 includes a charging circuit 210, an energy storage circuit 220, and a discharging circuit 230. The battery 310 selected as the target power supply battery charges the energy storage circuit 220 through the charging circuit 210, and when the target object meets the condition of being treated by electric shock, the energy storage circuit 220 performs electric shock treatment on the target object through the pair of electrode plates 700 by the discharging circuit 230.

The defibrillator also includes a processor 600, and the processor 600 analyzes the electrocardiogram signal obtained by the detection module 100 to determine whether the target subject satisfies a shock condition. For example, when it is determined from the ECG signal that the heart rhythm of the target subject includes at least one of ventricular fibrillation, ventricular tachycardia and ventricular flutter, it may be determined that the target subject satisfies the shock condition. When the heart rhythm of the target subject is judged to be any one of bradycardia, electromechanical separation, ventricular spontaneous rhythm and normal rhythm according to the ECG signal, it can be judged that the target subject does not satisfy the electric shock condition. When the target object is judged to meet the condition of being shock-treated, the battery 310 selected as the target power supply battery charges the energy storage circuit 220 through the charging circuit 210, and the energy storage circuit 220 applies defibrillation voltage to the target object through the pair of electrode plates 700 by the discharging circuit 230 so as to perform shock treatment on the target object.

In one embodiment, a shock instruction is automatically triggered when the target subject meets a shock condition. In another embodiment, the defibrillator includes a discharge button that, when pressed, triggers a shock instruction. Specifically, when the target object meets the shock condition, the alarm unit of the defibrillator sends out prompt information for prompting that the target object can be shocked, and the operator can press the discharge button according to the prompt information to trigger the shock instruction. When a shock command is triggered, the tank circuit 220 performs shock therapy on the target subject through the discharge circuit 230 via the pair of electrode pads 700.

In one embodiment, the processor 600 is further configured to control the battery management module 400 to supply power to the rescue module 200 no later than the detection module 100. In other words, the power supply to the rescue module 200 is performed at a timing earlier than the power supply to the detection module 100, or the power supply to the rescue module 200 and the power supply to the detection module 100 are performed simultaneously. Generally, when the detection module 100 detects that the target object needs to be treated, the treatment module 200 may be able to treat the target object after a preset time for charging. Compared with the case that the detection module 100 supplies power to the treatment module 200 when detecting that the target object meets the treatment condition, in the present embodiment, the power supply time for the treatment module 200 is no later than the power supply time for the detection module 100, and the detection module 100 detects the target object and simultaneously charges the treatment module 200, when the detection module 100 detects that the target object needs to be treated, the treatment module 200 can treat the target object, so that the time required for treating the target object when determining that the target object needs to be treated is shortened, the treatment module is beneficial to treating the target object as soon as possible in an emergency, and the probability of recovering the life of the target object is improved.

Specifically, in the defibrillator, the processor 600 controls the battery management module 400 to charge the charging circuit 210 no later than when at least one of the impedance detection module 110 and the electrocardiogram sensing module 120 is powered.

The medical device 1 according to the third embodiment of the present application is basically the same as the medical device 1 according to the first and second embodiments, and the differences are described below.

Further, the control module 410 is electrically connected to each battery 310 through a wire 530 and a switch 540, respectively, and the control module 410 is further configured to control on/off of each switch 540, when the battery 310 is turned on under the control of the control module 410, the battery 310 provides power for the detection module 100 or the rescue module 200, and when the control module 410 controls the corresponding switch 540 to be turned off, the battery 310 does not provide power for the detection module 100 or the rescue module 200.

Further, when the detection module 100 operates, the control module 410 controls the switch 540 corresponding to the battery 310 with the largest capacitance to be closed, so that the battery 310 with the largest capacitance supplies power to the detection module 100.

Further, when the rescue module 200 is in operation, the control module 410 controls the switches 540 corresponding to all the batteries 310 to be closed, so that all the batteries 310 are powered by the rescue module 200.
