[0002] In the field of medical monitoring, telemetry equipment is widely used for long-term, continuous, dynamic monitoring of patients' physiological parameters such as electrocardiogram, blood pressure, respiration, blood oxygen saturation, body temperature, and pulse rate. These devices are typically portable, allowing patients to move freely within their wards while ensuring healthcare professionals can access their physiological data in real time. However, the continuous operation of telemetry equipment is highly dependent on battery power, and battery capacity is limited. When the battery level drops below a preset value, it needs to be replaced to ensure normal operation. Currently, most telemetry devices experience power interruptions when replacing batteries, causing the equipment to temporarily stop working. This prevents healthcare professionals from obtaining crucial patient physiological information in a timely manner, potentially delaying diagnosis or treatment. Utility Model Content

[0016] The beneficial effects of the embodiments in this application compared with the prior art are:

[0017] The battery swapping and stabilization circuit provided in this application includes a current limiting unit, a first unidirectional conduction unit, a second unidirectional conduction unit, and an energy storage unit. When the battery charge is greater than a first preset charge, indicating that the battery is fully charged or has sufficient charge, the battery outputs a first voltage to the current limiting unit. The current limiting unit limits the current and adjusts the voltage of the first voltage, outputting a second voltage to the first unidirectional conduction unit. Based on its unidirectional conduction characteristic, the first unidirectional conduction unit directs current to the energy storage unit and outputs a third voltage to enable the energy storage unit to complete charging. This process effectively prevents current reverse flow, ensuring the safety and reliability of the energy storage unit's charging. When the battery charge is less than or equal to the second preset charge, indicating that the battery is insufficient and needs to be replaced, the energy storage unit begins to discharge, outputting a fourth voltage to the second unidirectional conduction unit. The second unidirectional conduction unit, also based on its unidirectional conduction characteristic, outputs a stable supply voltage to the device, supplying power to the device. Therefore, the battery swapping and stabilization circuit provided in this application embodiment can continuously supply power to the electrical equipment through the energy storage unit when the battery power is insufficient and the battery needs to be replaced, ensuring that the electrical equipment can still work stably in the absence of a battery. This effectively solves the problem that existing electrical equipment will temporarily stop working due to power interruption during the battery replacement process, and realizes the continuity and stability of power supply to the electrical equipment.

[0018] It is understood that the beneficial effects of the second and third aspects mentioned above can be found in the relevant descriptions in the first aspect above, and will not be repeated here. Attached Figure Description

[0029] In the field of medical monitoring, telemetry equipment is widely used for long-term, continuous, dynamic monitoring of patients' physiological parameters such as electrocardiogram, blood pressure, respiration, blood oxygen saturation, body temperature, and pulse rate. These devices are typically portable, allowing patients to move freely within their wards while ensuring healthcare professionals can access their physiological data in real time. However, the continuous operation of telemetry equipment is highly dependent on battery power, and battery capacity is limited. When the battery level drops below a preset value, it needs to be replaced to ensure normal operation. Currently, most telemetry devices experience power interruptions when replacing batteries, causing the equipment to temporarily stop working. This prevents healthcare professionals from obtaining crucial patient physiological information in a timely manner, potentially delaying diagnosis or treatment.

[0030] To address the aforementioned issues, the battery swapping and stabilization circuit provided in this application includes a current-limiting unit, a first unidirectional conduction unit, a second unidirectional conduction unit, and an energy storage unit. When the battery charge exceeds a first preset charge level, indicating sufficient or full charge, the battery outputs a first voltage to the current-limiting unit. The current-limiting unit limits the current and adjusts the voltage of the first voltage, outputting a second voltage to the first unidirectional conduction unit. Based on its unidirectional conduction characteristic, the first unidirectional conduction unit directs current to the energy storage unit and outputs a third voltage to complete charging of the energy storage unit. This process effectively prevents reverse current flow, ensuring the safety and reliability of charging the energy storage unit. When the battery charge is less than or equal to the second preset charge level, indicating insufficient battery charge and requiring replacement, the energy storage unit begins discharging, outputting a fourth voltage to the second unidirectional conduction unit. The second unidirectional conduction unit, also based on its unidirectional conduction characteristic, outputs a stable supply voltage to the device, providing power to the device. Therefore, the battery swapping and stabilization circuit provided in this application embodiment can continuously supply power to the electrical equipment through the energy storage unit when the battery power is insufficient and the battery needs to be replaced, ensuring that the electrical equipment can still work stably in the absence of a battery. This effectively solves the problem that existing electrical equipment will temporarily stop working due to power interruption during the battery replacement process, and realizes the continuity and stability of power supply to the electrical equipment.

[0031] To illustrate the technical solution described in this application, specific embodiments are provided below.

[0032] Figure 1 A schematic block diagram of a battery swapping and stabilization circuit 10 according to an embodiment of this application is shown. See also... Figure 1As shown, the battery swapping and stabilization circuit 10 is applied to a telemetry device. The battery swapping and stabilization circuit 10 includes a current limiting unit 101, a first unidirectional conduction unit 102, a second unidirectional conduction unit 103, and an energy storage unit 104. The first unidirectional conduction unit 102 is electrically connected to the current limiting unit 101, the second unidirectional conduction unit 103, and the energy storage unit 104, respectively. The second unidirectional conduction unit 103 is electrically connected to the energy storage unit 104. The current limiting unit 101 is used to electrically connect to the battery 20 and the electrical device 30, respectively. The second unidirectional conduction unit 103 is used to electrically connect to the battery 20 and the electrical device 30, respectively.

[0033] Specifically, when the battery 20's charge is greater than the first preset charge, indicating that the battery 20 is fully charged or has sufficient charge, the battery 20 outputs a first voltage to the current limiting unit 101. The current limiting unit 101 limits the current and adjusts the voltage of the first voltage, outputting a second voltage to the first unidirectional conduction unit 102. Based on its unidirectional conduction characteristic, the first unidirectional conduction unit 102 directs the current to the energy storage unit 104 and outputs a third voltage to complete the charging of the energy storage unit 104. This process effectively prevents current reverse flow, ensuring the safety and reliability of charging the energy storage unit 104. When the battery 20's charge is less than or equal to the second preset charge, indicating that the battery 20 is low on charge and needs to be replaced, the energy storage unit 104 begins to discharge, outputting a fourth voltage to the second unidirectional conduction unit 103. The second unidirectional conduction unit 103, also based on its unidirectional conduction characteristic, outputs a stable supply voltage to the electrical device 30, supplying power to the electrical device 30. Therefore, the battery swapping and stabilization circuit 10 provided in this application embodiment can continuously supply power to the electrical device 30 through the energy storage unit 104 when the battery 20 is low in power and needs to be replaced. This ensures that the electrical device 30 can still work stably when there is no battery 20, effectively solving the problem that the existing electrical device 30 will temporarily stop working due to power interruption during the battery 20 replacement process, and realizing the continuity and stability of power supply to the electrical device 30.

[0034] It should be noted that when the battery level of 20 is greater than the first preset level, it indicates that the battery level of 20 is sufficient or fully charged. When the battery level of 20 is less than or equal to the second preset level, it indicates that the battery level of 20 is insufficient and needs to be replaced. Therefore, the first preset level can be used as a threshold when the battery level of 20 is high, and the second preset level can be used as a threshold when the battery level of 20 is low and needs to be replaced.

[0035] For example, the first preset charge level can be a battery 20 that is close to full charge or fully charged, the second preset charge level can be 10%, or the voltage corresponding to the battery being at the second preset charge level can be 3.3V.

[0036] It should be noted that battery 20 is electrically connected to device 30. When the battery 20 has a charge greater than the second preset charge and does not need to be replaced, battery 20 supplies power to device 30, which includes a telemetry host and external devices electrically connected to the telemetry host.

[0037] In one embodiment of this application, such as Figure 2 As shown, the current limiting unit 101 includes a first resistor R1 and a second resistor R2. The first end of the first resistor R1 and the first end of the second resistor R2 are both used to be electrically connected to the battery 20, and the second end of the first resistor R1 and the second end of the second resistor R2 are both electrically connected to the first unidirectional conduction unit 102.

[0038] Specifically, the first resistor R1 and the second resistor R2 are connected in parallel, both for current limiting protection, limiting the current flowing into subsequent circuits (such as the first unidirectional conduction unit 102 and the energy storage unit 104) to avoid excessive current from damaging subsequent electronic components.

[0039] It should be noted that the resistance values ​​and connection relationship of the first resistor R1 and the second resistor R2 are not limited here. For example, the resistance values ​​of the first resistor R1 and the second resistor R2 can both be fixed or variable, and the first resistor R1 and the second resistor R2 can be connected in parallel or in series. Furthermore, besides using one first resistor R1 and one second resistor R2, designers can also use other numbers of first resistors R1 and second resistors R2. For example, two or three first resistors R1 can be connected in series or parallel, and two or three second resistors R2 can be connected in series or parallel. This application... Figure 2 Only the circuit structure of the current limiting unit 101, which includes a first resistor R1 with a fixed resistance value and a second resistor R2 with a fixed resistance value connected in parallel, is shown. The first resistor R1 and the second resistor R2 can be replaced with resistors of different numbers, types or connection relationships. The basic working principle is similar, and will not be described in detail here.

[0040] For example, designers can select the resistance values ​​of the first resistor R1 and the second resistor R2 according to the actual situation. For instance, using... Figure 2 For example, select a first resistor R1 and a second resistor R2 connected in parallel. The resistance values ​​of both the first resistor R1 and the second resistor R2 can be selected as 100 ohms.

[0041] It should be noted that the embodiments provided in this application only show one circuit structure as the current limiting unit 101, and do not mean that only this one circuit structure can realize the function of the current limiting unit 101. Other circuit structures that can realize this function can also be substituted, and are not limited to this.

[0042] In one embodiment of this application, such as Figure 2 As shown, the first unidirectional conduction unit 102 includes a first diode D1. The anode of the first diode D1 is electrically connected to the current limiting unit 101, and the cathode of the first diode D1 is electrically connected to the second unidirectional conduction unit 103 and the energy storage unit 104, respectively.

[0043] Specifically, the first diode D1 provides unidirectional conduction protection, with its anode receiving the second voltage. Due to its unidirectional conduction characteristic, when the anode voltage is higher than the cathode voltage, the first diode D1 is in a forward-conducting state, allowing current to flow smoothly from the anode to the cathode. That is, the second voltage is converted into a third voltage through the conducting first diode D1 and output to the energy storage unit 104 to charge it. This unidirectional conduction characteristic ensures that the current flows only in a predetermined direction, allowing the charging process to proceed in an orderly manner. During this process, due to a certain voltage drop in the first diode D1, the second voltage is greater than the third voltage. Simultaneously, during the charging of the energy storage unit 104, the first diode D1 also prevents the current in the energy storage unit 104 from flowing back into the current-limiting unit 101 and the battery 20. This avoids damage to the battery 20 and other circuit components, effectively protecting the safety and stability of the battery swapping and stabilization circuit 10. In addition, the first diode D1 can isolate the circuit areas where the current limiting unit 101 and the energy storage unit 104 are located, avoiding interference between different voltage areas and protecting the devices in the energy storage unit 104.

[0044] It should be noted that the first diode D1 is selected with a low forward conduction voltage. A low forward conduction voltage means a small voltage drop. Under the same charging current, the power consumed by the first diode D1 is reduced, thereby reducing energy loss during the entire charging process. More electrical energy can be effectively transferred to the energy storage unit 104 for storage, improving the conversion efficiency of electrical energy from the battery 20 to the energy storage unit 104. At the same time, the smaller forward conduction voltage drop makes the voltage loss relatively stable when current flows through the first diode D1. This helps to provide a more stable charging voltage for the energy storage unit 104, ensuring the charging effect and performance stability of the energy storage unit 104.

[0045] For example, the designer can select the model of the first diode D1 according to the actual situation. For example, the first diode D1 can be a 1N5819 diode.

[0046] It should be noted that the embodiments provided in this application only show one circuit structure as the first unidirectional conduction unit 102, and do not mean that only this one circuit structure can realize the function of the first unidirectional conduction unit 102. Other circuit structures that can realize this function can also be substituted, and are not limited to this.

[0047] In one embodiment of this application, such as Figure 2 As shown, the second unidirectional conduction unit 103 includes a second diode D2. The anode of the second diode D2 is electrically connected to the first unidirectional conduction unit 102 and the energy storage unit 104, respectively, and the cathode of the second diode D2 is used to electrically connect to the battery 20 and the electrical device 30, respectively.

[0048] Specifically, the second diode D2 provides unidirectional conduction protection, and the energy storage unit 104 outputs a fourth voltage to the anode of the second diode D2. Due to the unidirectional conduction characteristic of the second diode D2, when the anode voltage is higher than the cathode voltage, the second diode D2 is in a forward conducting state, allowing current to flow smoothly from the anode to the cathode. That is, the fourth voltage is converted into a supply voltage through the conducting second diode D2 and output to the electrical device 30 to charge it. This unidirectional conduction characteristic ensures that the current flows only in a predetermined direction, allowing the charging process to proceed in an orderly manner. During this process, due to a certain voltage drop in the second diode D2, the fourth voltage is greater than the supply voltage. Furthermore, the second diode D2 can isolate the circuit areas where the energy storage unit 104 and the electrical device 30 are located, avoiding interference between different voltage regions and protecting the electrical device 30.

[0049] It should be noted that the second diode D2 is selected with a low forward conduction voltage. A low forward conduction voltage means a small voltage drop. Under the same charging current, the power consumed by the second diode D2 is reduced, thereby reducing energy loss during the entire charging process. More electrical energy can be effectively transferred to power device 30, improving the conversion efficiency of electrical energy from energy storage unit 104 to power device 30. At the same time, the smaller forward conduction voltage drop makes the voltage drop relatively stable when current flows through the second diode D2. This helps to provide a more stable supply voltage to device 30, ensuring the stability of the power supply to device 30.

[0050] For example, the designer can select the model of the second diode D2 according to the actual situation. For example, the model of the second diode D2 can be a 1N5819 diode.

[0051] It should be noted that the embodiments provided in this application only show one circuit structure as the second unidirectional conduction unit 103, and do not mean that only this one circuit structure can realize the function of the second unidirectional conduction unit 103. Other circuit structures that can realize this function can also be substituted, and are not limited to this.

[0052] In one embodiment of this application, such as Figure 2As shown, the energy storage unit 104 includes a first capacitor C1. The first end of the first capacitor C1 is electrically connected to the first unidirectional conduction unit 102 and the second unidirectional conduction unit 103, respectively, and the second end of the first capacitor C1 is grounded.

[0053] Specifically, the first capacitor C1 is used for energy storage and release. When the battery 20 is fully charged, after the telemetry device is powered on, the battery 20 can charge the first capacitor C1 through the first resistor R1, the second resistor R2, and the first diode D1, at which time the first capacitor C1 is used for energy storage. When the battery 20 is low on power, the first capacitor C1 releases energy, and the electrical energy is transferred to the device 30 through the second diode D2 to power the device 30. This allows for temporary and necessary power support to the device 30 when the battery 20 needs to be replaced due to low power, ensuring the normal operation of the device 30 and preventing the device 30 from shutting down or malfunctioning due to power interruption from the battery 20, thus achieving a smooth transition during the battery replacement process.

[0054] For example, designers can select the model, type, and capacitance of the first capacitor C1. For instance, the model of the first capacitor C1 could be CAP2_22R0X16R0_11R8-V, the type could be a farad capacitor, and the capacitance could be 1.5F. Compared to a regular capacitor, selecting a 1.5F farad capacitor as the first capacitor C1 allows for the storage of relatively more energy, providing sufficient power support for the electrical device 30 and ensuring its continuous and stable operation during battery 20 replacement. For example, using a 1.5F farad capacitor allows the electrical device 30 to remain in standby mode for at least 10 seconds without battery 20. That is, when the operator is replacing battery 20, the first capacitor C1 can continuously discharge to keep the electrical device in standby mode for at least 10 seconds, ensuring continuous and stable operation during battery 20 replacement. Simultaneously, the farad capacitor has an extremely short charging time constant, enabling the charging process to be completed in a short time, improving the charging and discharging efficiency and stability of the first capacitor C1.

[0055] It should be noted that, in addition to the first capacitor C1, the energy storage unit 104 can also use other energy storage devices that can be charged and discharged, such as backup batteries, supercapacitors, capacitor arrays, battery packs, etc., depending on the actual situation.

[0056] In one embodiment of this application, such as Figure 2 As shown, the common terminal of the first unidirectional conduction unit 102 and the second unidirectional conduction unit 103 serves as a test node, which is used to connect to the test equipment.

[0057] Specifically, the common terminal of the cathode of the first diode D1, the anode of the second diode D2, and the first terminal of the first capacitor C1 serves as a test node, connected to a test device. The test device can be a voltmeter, allowing real-time monitoring of the voltage value at the test node to determine the charging and discharging voltage of the first capacitor C1 and whether any abnormalities have occurred during the charging and discharging process. Alternatively, the test device can be an ammeter, allowing real-time monitoring of the current value at the test node to determine the current flowing through it and whether any abnormalities have occurred during the charging and discharging process. Furthermore, by testing at this test node, it can be determined whether the first diode D1, the second diode D2, and the first capacitor C1 are functioning correctly. If a fault occurs, the fault location can be quickly identified, facilitating timely repair and replacement, and ensuring the normal operation of the battery swapping and stabilization circuit 10.

[0058] This application also discloses a power supply device, including a battery 20 and the aforementioned battery swapping and stabilization circuit 10. The battery 20 is electrically connected to the current limiting unit 101 and the second unidirectional conduction unit 103 in the battery swapping and stabilization circuit 10. By using the aforementioned battery swapping and stabilization circuit 10, the power supply device can ensure the stability and reliability of the power supply to the electrical equipment 30.

[0059] This application also discloses a telemetry device, including a telemetry host and the aforementioned power supply unit, wherein the power supply unit is disposed within the telemetry host. By employing the aforementioned power supply unit, the telemetry device can ensure stable power support, guaranteeing its continuous operation over extended periods.

[0060] In one embodiment of this application, the telemetry device further includes a data acquisition module and a control module, with the data acquisition module and the control module electrically connected. The data acquisition module is used to acquire the physiological parameters of the user being measured and transmit the physiological parameters to the control module. The control module is used to output a control signal based on the physiological parameters, wherein the physiological parameters include at least one of electrocardiogram (ECG), blood pressure, blood oxygen saturation, and body temperature.

[0061] Specifically, the acquisition module is connected to the telemetry host via its peripheral interface and is located outside the telemetry host, while the control module is located inside the telemetry host. The acquisition module includes an ECG acquisition unit, a blood pressure acquisition unit, a blood oxygen saturation acquisition unit, and a body temperature acquisition unit. All of these units are electrically connected to the control module. The ECG acquisition unit acquires ECG signals and transmits them to the control module; the blood pressure acquisition unit acquires blood pressure signals and transmits them to the control module; the blood oxygen saturation acquisition unit acquires blood oxygen saturation signals and transmits them to the control module; and the body temperature acquisition unit acquires body temperature signals and transmits them to the control module. The control module outputs corresponding control signals based on the ECG, blood pressure, blood oxygen saturation, and body temperature signals.

[0062] In one embodiment of this application, the telemetry host also includes a voice broadcast module for playing relevant information generated by the control module based on the collected physiological parameters. When the control module receives the electrocardiogram (ECG) signal from the ECG acquisition unit, the blood pressure signal from the blood pressure acquisition unit, and the body temperature signal from the body temperature acquisition unit, it analyzes and processes these physiological parameters. If a parameter exceeds the normal range, the control module generates a corresponding abnormality alert and transmits it to the voice broadcast module. The voice broadcast module then clearly broadcasts alerts such as "ECG abnormal, please check immediately," "Blood pressure too high, please pay attention to your physical condition," and "Body temperature outside the normal range" to medical personnel or the user, ensuring that relevant personnel are aware of any abnormalities in the physiological parameters immediately so that timely countermeasures can be taken. Furthermore, during normal monitoring, the voice broadcast module can also periodically broadcast the current values ​​of various physiological parameters, such as "Current ECG is normal, systolic blood pressure is XXX mmHg, diastolic blood pressure is XXX mmHg, body temperature is XX.XX℃," allowing users to understand their basic physiological status at any time without looking at the screen. In addition to voice alarms from the voice broadcast module, other alarm methods such as light alarms and vibration alarms can also be included. When physiological parameters exceed set thresholds or the system malfunctions, multiple alarm methods can be used to promptly alert relevant personnel.

[0063] It should be noted that the telemetry host also includes a communication module, used to transmit the collected physiological parameters and data processed by the control module to a remote monitoring center or other terminal devices. Common communication methods include Bluetooth (BT), Wi-Fi, 4G / 5G, and other wireless communication technologies to achieve long-distance data transmission and interaction. The telemetry host also includes a storage module for storing the collected physiological parameters, data generated by the control module, and system configuration information. This storage can be a flash memory chip, hard drive, or other storage medium, allowing for data retrieval, analysis, and backtracking when needed.

[0064] It should be noted that the telemetry equipment provided in this application uses new lightweight materials, resulting in a significant reduction in weight and making it more portable. At the same time, the telemetry equipment has a compact and exquisite design, with a greatly reduced overall size, making it easier to carry and move more conveniently and quickly.
