[0004] Nasal continuous positive airway pressure (CPAP) therapy in the treatment of obstructive sleep apnea (OSA) The premise is that, for example, the soft palate and tongue are pushed forward toward the posterior oropharyngeal wall. By lowering or retracting the airway pressure, the continuous positive airway pressure therapy acts as a pneumatic splint, Such positive airway pressure prevents upper airway closure from occurring. Different sleep disordered breathing events are detected. Similarly, the airway pressure can be adjusted automatically to different levels to help the patient breathe more easily. Increase in pressure(s) during inhalation and pressure(s) during exhalation By lowering the pressure can also be changed in coordination with the patient's breathing.

The flow generator may include a servo-controlled motor, a volute, and an inlet forming a blower. In some cases, the inertia of the motor and impeller may be overcome. Thus, a brake for the motor may be implemented that reduces the blower speed more rapidly. This braking allows the blower to synchronize the lower pressure state with the exhalation, regardless of inertia. In some cases, the respiratory treatment device may be able to achieve a higher rate of is generated as an alternative to motor speed control to vary the pressure delivered to the patient. These sensors may also include a valve that allows the trapped air to be released to the atmosphere. , motor speed, mass flow rate and outlet pressure may be measured (e.g., pressure transducer The device incorporates a humidifier and / or heater element in the path of the air delivery circuit. The controller may optionally include integrated data retrieval and display capabilities. may include data storage capacity not including

Generally, power plugs (e.g., alternating current (AC) outlets commonly found in homes, businesses, and hospitals) However, there are cases where the power plug is not available. For example, For example, during a power outage or when the user of the breathing device is not near an AC outlet, the power Lagu may not be available.

[0027] 6 Detailed Description 6.1 Overview Before describing the present technology in more detail, it is important to understand that the present technology is It should be understood that the present invention is not limited to the specific embodiments that may be used. The terminology used herein is for the purpose of describing the specific embodiments described herein. It should also be understood that this is not limiting.

[0028] As respiratory treatment devices (e.g., PAP devices) become smaller, the need for power plug sources or other Autonomous with respect to its own device at a location away from an external power source (e.g., DC power) In this regard, there are users who wish to obtain the benefits of PAP devices. It is designed with portability to allow mobility within a place such as a home, a place of business, or a hospital. For example, a user may use the Other areas where electrical outlets are unavailable or inconveniently located or where power plugs are not available Patients may wish to utilize their own breathing device in the

[0029] Alternative and / or backup to respiratory therapy devices (e.g., PAP devices) A battery pack may be used to provide power. The device may be configured to operate at voltages above or below about 24 V, for example. Mass-produced high-capacity battery cells are needed to power such devices. Although it provides sufficient energy, most of it is available at a given voltage (e.g., 4V). Any deviation from these prescribed voltages will result in increased costs and / or This may lead to a reduction in power capacity.

[0030] Respiratory therapy devices (including the internally mounted blower and any other associated components) To achieve the voltage required to operate the UPS (including the UPS) at, for example, approximately 24V or higher or lower In order to achieve this, multiple battery cells may be arranged in series within a battery pack. If multiple battery cells are arranged in series, this leads to an increase in the bulk and size of the battery pack. Additionally, with each additional battery cell, the amount of heat output from the battery pack may be increased. This may increase the surface area of ​​the battery pack, which requires proper heat dissipation. Moreover, the voltage of a battery cell changes as the stored charge is lost or depleted. The respiratory treatment device is designed to operate at a particular / desired voltage. Therefore, it is desirable to have a power supply to ensure / regulate the desired voltage.

[0031] To achieve output voltage regulation, a DC / DC converter with high conversion efficiency and For example, a battery with a lower nominal voltage (e.g., about 12V) can be mounted together. The terry pack may be connected to a DC / DC converter. The DC / DC converter may optionally It may be integrated into the battery pack or into the respiratory treatment device (e.g., in the housing). The power signal from the battery can be transferred to the respiratory therapy device from a lower voltage (e.g., about 12V). The higher operating voltage of the device (e.g., PAP device) (e.g., approximately 24V or higher or lower However, the energy consumption of the DC / DC converter is Unless otherwise noted, the battery pack will lose its useful life (e.g., between therapy sessions) if left unattended. This can cause a significant decrease in the useful life of the power supply or the useful life at the point of sale. If the / DC converter is switched off, when the user activates its "on" button , the PAP device cannot be switched on because power to the PAP device is not available Therefore, the user must always switch the DC / DC converter to the "on" or "off" state. " state, which reduces user convenience.

[0032] Therefore, in some versions of the technology, the device may be used without being plugged in. A power supply for portable operation of the respiratory treatment device may be implemented. John has a voltage that is different from the voltage of the flow generator of a respiratory treatment device (e.g., a PAP device). The power subsystem may include a power subsystem capable of operating at low voltage. The power subsystem may include, for example, a standby mode For use with respiratory therapy devices configured to enter a "standby" mode by incorporating a The standby mode circuitry may include a battery pack for storing the respiratory therapy device control Switch the DC / DC converter in the battery pack on until an "on" signal is received from the controller. The standby mode circuitry allows the power supply to be switched "off" in "standby" mode. At this time, the energy consumption from the battery pack (i.e., the battery cell) is almost When a DC / DC converter is switched on, e.g. For example, a lower voltage (e.g., battery output voltage) can be used to power the therapy operation of a respiratory therapy device. Conversion to the higher operating voltage required can be performed.

[0033] The battery pack may be used, for example, to generate therapeutic pressure or generate airflow. For example, the power supply 100 shown in FIG. 1A and FIG. 1B may be configured to power a respiratory treatment device. As shown, the housing 170 of the battery pack 102 includes a locking mechanism 111 and a PAP and a guide slot 160 for connecting / inserting the device into the battery pack. To release the PAP device from the battery pack 102, a release button 110 is In addition, the housing 170 can be connected to an external power source (e.g., a power plug source). A power connector 130 (e.g., an AC or DC connector) for a battery pack that may be connected Other components of the battery pack 102 include a battery life Battery life indicator actuator 1 which initiates operation of battery life indicator 120 40. The battery life indicator 120 remains in the battery pack 102. The battery pack is intended to provide ) into a patient interface (e.g., full face mask, nasal pillows, nasal cannula, nasal mask, etc.) An internal flow generator (e.g., a motor and (including the impeller and the servo controller blower) The battery pack 102 may include an air outlet 150 for delivering Air is drawn through the housing of the block 102 into the flow generator of the PAP device 202. A mesh flow generator inlet 155 (e.g., a filter) configured to filter the air. may contain

For example, as shown in Figures 2A and 2B, The PAP device 202 is supported by a guide rail 210 or The guide rails 210 or rails may be on each side. The guide slots 160 are arranged so that the guide slots 160 can be inserted into the guide slots 160. The guide slots 160 are arranged on each side. The guide rails 2 are complementary to the rails of the battery pack 102. 10 together with the guide slot 160 to allow electrical connection of the battery pack 102 The connection / alignment between the connector and the PAP device 202 can be simplified and highly accurate. In this regard, the guide rail 210 may be inserted into the guide slot 160. Then, the guide rail 210 is slid downward over the guide slot 160. When the battery is charged, the PAP device 202 is inserted into the battery pack 206 as shown in FIGS. 3A and 3B. The PAP devices 2 can be arranged in a predetermined configuration within the housing 170 of the device 102. 02 may also include a connector 212. The connector 212 is latched into the locking mechanism 111. 3A and 3B, or may be otherwise attached within the locking mechanism 111. As shown in FIG. 3B, the components are locked or otherwise attached together. When attached, the PAP device 202 can fit compactly within the housing 170. The connection between the battery pack 102 and the PAP device 202 is released when the locking mechanism 111 is released. It may be maintained until released by action of release button 110 .

[0035] The PAP device 202 includes a blower, an inlet filter, various sensors and a microprocessor. a processor-based controller, connectable to a patient interface via an air circuit Power to the PAP device 202 can be provided by a power to switch 230. In this regard, the power button of the PAP device can be controlled by a switch 230. Activating and deactivating the PAP device turns the user "on" and As described in more detail herein, the power A button or switch 230 turns the DC / DC converter of the battery pack 102 "on." and an "off" state.

[0036] The PAP device may communicate with other computing devices. In this regard, the PAP device may PAP devices via Bluetooth or other such wireless communication protocols To connect to other computing devices (e.g. tablets, smartphones, computers) Optionally, such communication may include a wireless pairing button 240. (e.g., using a wire in the power connector) or no pairing button may be required. For example, wired connections may be implemented with other data wire connections between system components. communication between devices (e.g., battery / PAP device and / or PAP device / The PAP device may be implemented as a single or multiple other computing devices. Status updates may include the power status of the battery pack 102, There may be force level reports, usage statistics for the PAP device 202 (e.g., therapy data (e.g., , flow rate or pressure), compliance data (e.g., PA (P) Device usage time, and other such usage data. This is achieved by configuring the PAP device or the battery pack in a physical user interface. The operating / control parameters of the PAP device (e.g., pressure and / or flow settings) without The PAP device may be able to set the meter. ED display) and a wider range of input control buttons (e.g. keyboard) This can facilitate further miniaturization of the portable size.

[0037] Although a PAP device is illustrated, other respiratory treatment devices as described herein may also be used. , may be similarly implementable (e.g., portable ventilatory support devices).

[0038] 6.2 Power composition The respiratory treatment device may be powered by any of several different types of power sources. For example, as shown in FIG. 4, an AC power source 410 (e.g., a power plug) may be , through an electrical connector 130 or an integral power cable of the battery pack / plug or via its housing a component of the PAP device 202 (e.g. , flow generator 404). In this regard, an AC power source 410 ( mains) is a power connector 1 using, for example, an AC-DC power converter plug pack power supply 30 to the flow generator 404 and / or to the battery pack 102 Thus, the AC power source 410 may be configured to convert the AC power signal to a DC power signal. The power supply may be connected through a C / DC adapter (not shown). The 120 volt (V) or 240 volt (V) alternating current (AC) power signal to be A 24V direct current (DC) signal can be received by the DC adapter and then by the AC / DC adapter. or to a higher or lower 12VDC signal. The converted DC signal can be, for example, The AC / DC adapter outputs a direct current to the generator 404 for charging the battery pack. and / or to the battery pack 102.

[0039] The respiratory treatment device may also be powered by a DC power supply 510, as shown in FIG. Similar to the connection to power supply 410, as described above, DC power supply 510 may be connected to It may be connected to the power connector 130 of the battery pack 102 or directly to the PAP However, the correct voltage (e.g., 24V or more) may be connected to the device 202. An input DC / DC converter 520 is connected in series to deliver the stratum corneum (bottom) to the respiratory treatment device. or a DC power supply 510 and the components of the PAP device 202 (e.g., flow generating The input DC / DC converter may be provided between the power supply 404 and the battery pack 102. 520 converts the voltage of the power signal received from the DC power supply 510 into the operation of the respiratory treatment device. and / or configured to convert the voltage to a voltage that may be suitable for charging a battery pack. In some versions, the DC power supply 510 can be 6V to 24V or The input may be a source that provides more or less than 100 volts (e.g., 12V or 24V). The DC / DC converter 520 converts this voltage into the operating voltage for the PAP device or battery pack. The voltage may be increased to a voltage (eg, 24V, or more or less).

[0040] If the power plug fails or is unavailable, the respiratory treatment device will not operate For example, the battery pack 102 may be powered by an AC power source 410 or a DC power source. When the flow generator of the PAP device 202 is disconnected from the battery pack 102, 404 may draw power from the battery pack 102. Thus, the conversion from power plug to battery power can be realized automatically. The battery pack 102 and / or the PAP device 202 automatically detects power plug loss. When a power plug loss is detected, the PAP The device 202 may automatically begin drawing power from the battery pack 102. In other versions, a user of the respiratory treatment device may need to recharge the battery (e.g., The device can be manually switched to draw power from a power pack 102.

[0041] The battery pack is used to power the respiratory therapy device from an external power source (e.g., AC or DC power). ) may be charged. In this regard, When connected to a PAP device 202 as shown in FIG. For example, the power required to operate the PAP device 202 may be prioritized. The power required to operate the flow generator 404 is prioritized over charging the battery pack 102. Therefore, the PAP device 202 draws high power from an external power source. When this happens, battery charging may pause or the charging rate may decrease. In an embodiment, the battery pack 102 may be directly connectable to an external power source to be charged. For example, the battery pack 102 is connected to a flow generator 404 of a PAP device. If not, it may be configured to connect to an external power source for charging.

The controller 670 may receive information about the components of the battery. Commands to control functions may be provided via SMB on connection 675. For example, The cross-controller passes information (e.g., the charge level of the battery pack) to the battery management module. The data may be received from the controller 630 over SMB on connection 675. The controller notifies the user interface 680 of the battery status.

In this regard, the user interface may display the battery charge status (e.g., percentage charge). to the user (time to full charge or charge limit) and / or to indicate operating status to the user. to users (e.g., time to battery depletion and / or The user interface 680 may be configured to The device may also accept input from a user. Such input may be in the form of one or more button actuation signals (e.g. When battery activity (e.g., button activation on or off) is detected, This may affect the internal power supply of the battery (starting or stopping). The user interface informs the user about the status of the battery charge when the user activates the button. A visual output of the input may be provided to the user.

[0050] Thus, in an embodiment of the present technology, the user interface 680 may include one or more inputs. These input devices may include force devices in the form of buttons (e.g., as shown in FIG. 2A and A power button (e.g., switch 230) in FIG. 2B allows human interaction with the device.

Such a user interface may allow a person to select values ​​and / or menus. menu options for example on a mobile processing device (e.g. running a control application) The smartphone processor (which is a part of the smartphone) is used to enable the selection of , can be constructed and deployed.

[0052] The battery power system 610 receives a power signal from a power supply unit (PSU) In some embodiments, the PSU connection 620 may be The power signal may be provided by a power connector 130 such as that shown in FIG. 1A. The conditioned power signal can then be routed to the flow generator via a flow generator connection 690. The power system 610 may be configured to detect if the current is in the wrong direction (e.g., , from the output to the input). The system 610 may include an internal rail or an internal power node (eg, a wired connection). These internal rails or internal power nodes are powered by the internal power circuitry 645. Provides internal DC power to the various components and modules.

[0053] A power signal is provided from the PSU connection 620 to the charger and input management module 625. The charger and input management module 625 may include one or more integrated circuits (e.g., For example, IC model number BQ24725 provided by Texas Instruments. These circuits are configured to monitor and control the charging of the cells in the battery pack 102. In this regard, the charger and input management module 625 may be configured to receive the power signal It can monitor the input voltage and current, as well as the power signal output for charging the battery cell. Thus, the battery charger circuit is connected to connection 675 for controlling the charging of the battery. In this regard, the battery management module 630 may have an integrated circuit that communicates with the battery management module 630 via SMB. The battery charger circuit provides overvoltage / undervoltage lockout and The current may be monitored and limited. The monitored power status and battery charge status may be The data may be sent to the microcontroller 670 over SMB on connection 675. The controller 670 may provide charging instructions to the charger and input management module 625. (For example, commands to control the voltage and current output to a battery cell).

[0054] The charger and input management module 625 includes circuits and circuit components that also provide power conditioning. For example, the charger and input management module 625 may include a It may control and / or minimize noise transmission and may provide electrostatic discharge and transient protection. The electrical and input module 625 may include overvoltage / undervoltage protection (e.g., lockout), input blocking under output fault conditions, and / or battery In some embodiments, the microcontroller may also provide battery charging capabilities. 670 may provide instructions to the charger and input management module 625 (e.g., connection 6 (Order in 75 to control the type and amount of power throttling through the SMB).

[0055] The battery may also include a battery management module 630. The battery management module 630 includes: The charging and discharging of the battery cell(s) of the module may be controlled. For example, The battery management module 630 may include one or more integrated circuits. Controlling the energy conservation of the battery(s), power state ( i.e., providing battery(s) power balance and charge capacity, charging current and and voltage requirements, and other such requirements via SMB in connection 675. The battery status information may be provided to the microcontroller 670. 0 provides instructions for charge rate etc. These are sent from the microcontroller 670. The battery management module 630 also transmits the battery charger via the SMB. Pack serial number traceability, lifetime usage data and finished product performance testing The data may be stored for testing after the battery is manufactured.

[0056] The battery management module 630 ensures that primary and secondary batteries remain within safe operating parameters. Thus, it may also provide protection for charging and discharging these battery(ies). One or more integrated circuits in the battery management module 630 provide charge and discharge protection. (e.g., battery parameter monitoring (e.g., overvoltage / undervoltage protection, overcurrent protection, overtemperature (protection against temperature / under-temperature, battery / voltage imbalance). In addition, one or more of the battery management modules The integrated circuitry of the device is designed to stop charging or discharging the battery cells if certain limits are exceeded. A battery protection cutoff may be provided to stop the discharge. If an unrecoverable fault condition is determined, the battery management module 630 may In some versions, the battery management module management IC (e.g., Texas Instruments BQ40Z50) and / or Or a battery overvoltage protection IC (e.g., Texas Instruments BQ2947 02).

[0057] The internal power circuit 645 may provide power to the internal circuitry within the battery pack 102. In this respect, this is done by distributing power to the pilot detection circuit 650 and the microcontroller 6 70. Power is delivered to the internal circuitry from the internal power circuitry via the internal DC rail. In some embodiments, the internal power circuitry 645 provides low voltage and low power signal supplies. The internal power circuitry 645 may provide a pilot supply, as described in more detail herein. A low current draw may be implemented for a "standby" mode associated with the detection circuit, thereby This limits the amount of power drawn from the battery.

[0058] The output direct current / direct current (DC / DC) converter 640 converts the It can be used to convert a nominal voltage, for example, to a regulated higher output voltage. For example, the 102 cell(s) in the battery pack may output more or less than 12V. The output power signal may then be output to the output DC / DC converter 640. 40, this 12V output power signal is connected to the operating voltage of the PAP device (e.g. a higher output The output power signal may be converted to a voltage (e.g., about 24 V or higher or lower). To maintain the power supply voltage within the operating parameters of the respiratory treatment device (e.g., 24V ± 1V), It may also be regulated by the output DC / DC converter 640 .

[0059] In some cases, the output DC / DC converter 640 may send regulation state updates to the microcontroller. to a controller (e.g., hardware and / or analog-to-digital conversion (ADC) and / or through a user interface via the CAN bus. For example, the output DC / DC converter 640 may track the voltage of the output power signal over time, and in this manner The microcontroller 670 may provide the information to the user. The signal may be optionally output via user interface 680.

[0060] In a particular embodiment, the output DC / DC converter is powered by a battery cell or cells. ) and other components of the battery pack 102. For example, If the battery cell fails or the battery is put into "standby" mode In this case, the output DC / DC converter is configured to This can ensure that the drug is not delivered to the affected area.

[0061] The battery may also include a pilot detection module 650. The pilot voltage source 650 serves as a pilot voltage source and supplies a pilot voltage (e.g., The power supply may provide a power supply voltage (power supply battery voltage) to the output block 655. This voltage may be unregulated. This high impedance voltage source may depend on the intended voltage of the battery pack. This pilot voltage is used to detect the pilot voltage. 50 indicates the specific range of current drawn from the battery cell from the PAP device 202. is also enabled if

[0062] The pilot detection module 650 detects the current draw on the pilot voltage supply. and if the current draw exceeds a predetermined threshold or if the current draw exceeds a predetermined threshold for a period of time. and starting or allowing internal power if the current is within a desired range. Thus, the pilot detection module 650 may include a To switch the power subsystem from "standby" to "on" mode so that It can be used for this purpose.

[0063] The output block 655 provides a connection between the battery pack 102 and the flow generator 404. In this regard, the output block 655 may be used to control the flow generator connection. The output block may provide an output power signal to the power supply 690 and may provide access to the CAN bus. The 655 also provides output voltage and current monitoring, output fault latch-off control, noise transfer control, and electrostatic discharge and transient protection to the battery pack 102 and the PAP device 202. For example, the output block 655 may provide a voltage and / or current output power signal. monitors the voltage and / or current of the output power signal and detects if a predetermined threshold is exceeded; In another example, the output block 655 may: Internal and external modules of the power system 610 and / or the battery pack 102 Optionally, the output block may handle transient signals and / or noise transmissions generated by the output block. The lock may provide ESD (electrostatic discharge) and / or EMI (electromagnetic interference) protection.

[0064] 6.4 Standby Mode Several internal circuit components of the battery system are required for the respiratory therapy device to operate. may draw power from the battery(ies) even if the device is not An internal battery that provides a regulated output voltage that is higher or lower than the external battery(ies) voltage. If the battery system includes additional circuitry (e.g., an output DC / DC converter 640), These battery systems typically allow the battery(ies) to wear out over time. Therefore, the converter can operate the battery even if other systems for the battery are not in operation. It can draw power continuously from one or more batteries. In one embodiment, a respiratory treatment device is configured for respiratory use (e.g., for providing treatment to a patient). It keeps many of the battery system's internal circuit components operational when not in operation. By not using / powering the device, the charge life of the battery cell(s) may be shortened. It can be improved.

[0065] Additionally, for ease of use, a power button (e.g., FIG. 2A and and is powered by actuation of a power button or switch 230 as shown in FIG. 2B. It may be more convenient for a user to operate a respiratory treatment device configured in this way. As a result, the PAP device will start to operate after activating the internal circuitry of the connected battery power source. Having to power 202 can be an inconvenience for users. Any (non-rechargeable) power from the battery cell(s) when the device is not activated An unpowered device is not being powered when no (or very little) power is being drawn from it. The device (e.g., PAP device 202) may also activate the battery along with itself. It may be desired.

[0066] Thus, in some versions, a respiratory treatment device (e.g., a PAP device) 202) may include power components to implement a "standby" mode. For example, the "standby" mode may be implemented by pilot detection module 6 of battery pack 102. 50, the microcontroller 670 and / or other components (e.g., In this regard, the present invention may be implemented with a PAP device 202 (a component that may be part of the PAP device 202). In this regard, the pilot detection module 650 detects the battery pack 102 and / or It may form part of the standby circuitry within the AP device 202. Thus, the circuitry for the standby mode may be integrated with the internal power circuitry 645.

[0067] Standby mode is the "standby" state (i.e., "off" state) and the "on" state. In this regard, the standby mode may be implemented. When the circuit components it supports are in a "standby" or "off" state, the battery The battery (e.g., battery pack 202) provides the power necessary for the operation of the therapy or PAP device. Secondly, the batteries in the battery pack 102, for example, are relatively high-intensity. A standby voltage of the impedance can be generated at the output block 655. The power supply may be at a lower voltage than the full output power signal that is normally enabled. A low voltage may be provided to the PAP device 202 via the flow generator connection 690. In some embodiments, some or all of the other internal components (e.g. For example, the output DC / DC converter 640) may be turned "off" and the standby mode may be "standby In this regard, some of the internal DC rails are not powered when the or all of the power to the The "on" mode may allow for reduced power and lower battery drain.

[0068] Conversely, when the standby circuit is in the "on" state, the flow generator 404 or respiratory therapy device a full / required operating output power signal (e.g., The battery pack is enabled to provide a 24V or higher (or lower). Regarding this point, when the standby circuit is in the "on" state, the internal components (e.g. The output DC / DC converter 640 circuitry can receive the power required to operate the internal DC rails. In this regard, power may be available primarily to the DC / DC converter, but not to the starter. This is not executed when the device is in standby mode.

[0069] In some versions of the standby circuit, the pilot detection module 650 The PAP device 202 draws power from a source (e.g., battery cell(s)). Monitor a particular current range (e.g., current measurements within a set of thresholds that represent a desired range) When such a current range is detected, the standby circuit state is The state switch can be automatically triggered from "off" to "on". When the standby circuit is in the "off" state, the pilot detection module 650 Due to the high impedance of the standby voltage supply, the output terminal of the pilot The detection module 650 consumes a relatively small amount of power while drawing a relatively small amount of power from a standby voltage source. It is possible to determine when to draw the amount of current drawn from the standby voltage source. The current flowing through the device exceeds a predetermined threshold and / or falls within a specified range for a specified period of time. If it is detected that the current draw is maintained, the pilot detection module 650 , the system may be switched from "standby" mode to "on" mode. In "on" mode, the battery pack provides a full output power signal to the PAP device. In this manner, the operation of the DC / DC converter 640 and the resulting balance The increase in voltage generated from the battery cell(s) is what causes the flow generator or PAP It can be triggered by device demand (e.g., activation). The device is configured to draw the range of current required to switch the standby circuitry. For example, the respiratory treatment device may include a button (e.g., a power button). The button is connected to a load (and switched on) to draw current within the required current range upon start-up. Optionally, the respiratory treatment device is turned "on" when the standby circuit is in its "on" state. This button switches the power supply to the AC / DC adapter and the power supply system. It may also perform the function of switching respiratory treatment devices when not in use.

[0070] The operating voltage of the component or components falls below the voltage for which it was designed. , which may cause adverse effects or even damage to the component(s) in question. The respiratory therapy device uses the battery pack when in "standby" mode ("off"). 102, the components in such therapeutic or PAP devices can receive low voltages. Certain components may receive low voltages, which may cause damage to them. To block these low voltages from reaching the components of the respiratory treatment device, The respiratory treatment device may include an under-voltage lockout circuit as shown in FIG. The voltage lockout circuit 702 can protect the respiratory treatment device from improper low voltage. Additionally, the under-voltage lockout circuitry may be provided with power from a battery pack and / or other power source. If the available voltage is limited (e.g., below a certain threshold), it draws very little power. You can avoid letting it out.

[0071] The under-voltage lockout circuit 702, in some versions, includes a transistor ( For example, a series P-channel MOSFET 710 and a first Zener diode may be included. The voltage delivered from the battery pack 102 to the under-voltage lockout circuit 702 may be When the input voltage 704 of the power signal is below the threshold voltage of the first Zener diode, an undervoltage The circuit connected to the lockout circuit 702 (e.g., the flow generator 404 or the PAP No power is provided to the device 202. The input voltage 704 is applied to the first Zener diode If the threshold voltage of the transistor 710 exceeds the threshold voltage of the transistor 711, the battery pack 1 The power provided by 02 is sent to a circuit connected to the undervoltage lockout circuit 702. obtain.

[0072] When a respiratory therapy device is powered on from “standby” mode, a certain known resistance is applied. Resistive or constant current draw from the respiratory treatment device to the output power terminals of the standby voltage supply Therefore, when the user tries to turn on the respiratory treatment device, the output voltage The range of current drawn at the force terminals may be known or predetermined. For example, The respiratory treatment device may be configured to supply a standby voltage source to a required range or over a predetermined threshold. A button (e.g., the power button in FIG. 2A and FIG. 2B ) that can provide a load that draws current from In some versions, the button may also include a When the standby circuit is in its "on" state or the respiratory therapy device is Turn on and off the respiratory therapy device when it is connected to a power adapter and not connected to a battery. Can be replaced.

[0073] The respiratory treatment device is in standby mode via a momentary press switch 715 and a current control circuit. The momentary press switch 715 may provide a controlled current drawn from a voltage source. In some versions, a current control circuit includes a resistor and a second Zener diode. 706. A momentary press switch 715 is activated (e.g., , the user presses the power button / switch 230), current draw at the battery output terminals Upon detection of a triggering event (e.g., when the power supply is drawn from the standby voltage source), If the current drawn is detected to exceed a predetermined threshold and / or the current draw is If the pilot is detected to be within a certain range for a certain period of time, The module can switch the system from "standby" mode to "on" mode. As mentioned above, when in "on" mode, the battery pack operates with a full output power signal. The device may provide a voltage and corresponding operating current to a respiratory treatment device. This may be considered as a dual stage start-up as described in more detail herein.

[0074] 8, the pilot detection module 650 detects the charge of the battery 820. This may be implemented with a high lateral current mirror circuit powered directly from the In this respect, the high lateral current mirror circuit 802 is implemented with a pair of PNP transistors. In some embodiments, other types of transistors or components include: A diode 808 and a resistor 809 may be used to implement a high lateral current mirror circuit. The reference leg formed by 10 provides a high impedance, low voltage supply to the PAP device. The high side current mirror can provide an output signal at the output terminal. The pilot current is fed to the battery cell (single 820 through the reference leg 806. will be done.

[0075] The pilot detection module 650 performs a dual stage start-up of the power system. This allows the power system to be switched from "standby" to "on" mode. At this point, the high side current mirror circuit 802 mirrors the current sent through the reference leg 806. Therefore, the same current flows from the PNP transistor of the high side current mirror circuit 802 to the The output is also sent to the monitoring IC of the power supply circuit. In the "leap state," the mirror current from the high side current mirror circuit 802 is 814, which serves as a voltage monitor. This voltage is input into the integrated circuit and the voltage is detected as a predetermined voltage in the first stage. The voltage window detector is configured to monitor the voltage to determine if it exceeds a predetermined voltage. If it determines that the threshold has been exceeded, the voltage window detector 814 requests a low voltage internal power signal. The power supply 830 may be routed to the internal power circuitry of the battery 102, as shown by Some components of the battery 102 (e.g., the microcontroller for the second stage) The NI PXIe-4100 is powered up (i.e., transitions to the “idle state”).

[0076] The microcontroller may, for example, decide the timing of the power system start-up in the "idle" state. In this regard, the microcontroller may instantiate a timer. and tracking the duration that the detected voltage is within a given voltage threshold or within a specific range. A detection may be initiated, for example, by comparing the elapsed time of a timing period to a timing threshold. That the voltage emitted exceeds a predetermined voltage threshold for a certain period or for a predetermined time period. If so, the microcontroller 670 determines whether the current drawn by the respiratory therapy device is When the device or PAP device is activated (e.g., from activation of momentary press switch 706 described above), The PAP device may determine that it is within range to indicate that it is attempting to start up. If it is determined that the battery pack is Enables the operation of a battery pack (e.g., upconverting voltage from a battery / cell) Enable the DC / DC converter for the battery pack to operate. The detected voltage can be activated at a predetermined timing, which causes the device to transition to a "supply state". If the threshold is not exceeded for a certain period or for a predetermined period associated with the The controller may instruct the pilot detection module 650 to brown out its internal power circuits, This prevents the PAP device from going into a "sleep" state and reduces the By using two-stage startup, the power system In some embodiments, this can be more secure because it can help to reliably avoid unexpected startups. In this case, the start-up of the power system is initiated by a false trigger of the pilot detection circuitry. The signal may be blocked for a period of time after the signal is determined by 670.

[0077] Therefore, in some versions, in "standby" mode, the DC / DC In this regard, the standby circuitry is Logic control connections to the microcontroller and DC / DC converter to control the output. A switch (e.g., a mosfet switch) may be included between the signal and the DC / DC The converter is disabled and the output voltage is the DC / DC converter (when in standby mode). This prevents the output voltage from reaching the output. There may be a fault condition and the microcontroller will be unable to detect the DC / DC converter output. may need to actively deassert this condition. Thus, a pilot voltage can be added to the output (to the flow generator) and the battery can be The power supply may be activated by a current generator that draws current from the pole voltage. The pilot source and pilot current sensing components also form part of the standby circuit. obtain.

[0078] 6.5 Power States The battery pack of the respiratory treatment device can operate in multiple power states. As shown in Table 1, the power states are "Sleep", "Idle", "Supply", "Charge" and Multiple power states may include "UPS" and "Power Supply Unit (PSU) installed. and / or active, or a flow generator (e.g., flow generator 404) is operating. The user has an input that requires power from a battery and / or is installed. The timeout may be based on whether the user is powering up, the battery is off, etc.

[0079] Table 1 below shows the characteristics of each power state of the battery (e.g., the occurrence of a given power state). the conditions necessary for, and the resulting effects on,the operation of the battery at a given power state) Similarly, the phase diagram shown in Figure 9 outlines these properties. [Table 1]

[0080] As shown in Figure 9, the PSU is disconnected from the battery pack or When the battery is inactive, it may be in a “sleep” power state 902. In the "group" power state, the internal rails, the microcontroller 670, and the charger component The input, power system 610 and power output may all be disabled.

[0081] In some versions of this “sleep” power state 902, the battery A standby voltage may be provided to its output terminal to provide power to the pilot detection module 650. Therefore, the battery must be ready to respond when a request to change power state is received (e.g. For example, the user may press the power button / switch 230 as shown in FIG. 9 and described above. Similarly, it can activate the battery status indicator. The battery check button allows you to power up your PAP device to the required level. It can operate on standby power without needing to activate a DC / DC converter to When the battery check button is pressed, the device transitions to the idle state. The state is then displayed as idle on the user interface.

[0082] In the "sleep" state, typically all switchable internal power sources are turned off. However, in the "idle" state, the internal The external rail can be turned on (without turning on the DC / DC converter) and the microcontroller The controller displays the status on the user interface and transmits the external The SM bus is implemented to perform communication with other units and internal communication on the SM bus.

[0083] The "Sleep" and "Idle" states are enabled / disabled by the internal power supplies. Several latch circuits are used. These latch circuits are connected to various inputs (e.g. controller, pilot circuit, user interface buttons, and / or input power Detection).

[0084] Therefore, the battery is not connected to the PSU and the flow generator. Or, when inactive, it may operate in an "Idle" power state 904. In the "power" state, the internal DC rails may be enabled and the microcontroller 670 may accept power. The charger components and power output may be disabled. Similar to the sleep power state 902, when the battery is in an “idle” power state, the battery Terry can activate the standby circuitry as described above.

[0085] If the PSU is not connected to the battery or is inactive as shown in Figure 9 If a flow generator connected to the battery is active, the battery goes into the "supply" power state. In the “supply” power state, the internal DC rails are enabled and the master The microcontroller 670 is then operational. In addition, full power output may be enabled. However, the charging capability can be disabled.

[0086] PSU connected to battery and flow generator not connected to battery The battery may be placed in the "charging" power state 908 even when inactive or inactive. In the “Charge” power state, the internal DC rails can be enabled and the microcontroller may receive power and run one or more peripheral devices. When the power output is disabled, the battery can be charged without draining. This can be done.

[0087] When both the PSU and flow generator are connected and active, the battery is In the “UPS” power state, the internal DC rails and The charger can be enabled. In addition, the microcontroller can receive power and control the peripherals. However, the power required for operation must be provided to the flow generator from an active PSU. So you can see voltage, current, amps or other such power output indicators The power output or charging power as measured may be reduced.

[0088] As shown in FIG. 9, components are turned on and / or off or removed. The battery can be switched between power states, e.g. When the power supply unit attached to the battery is turned on, the battery will be in an "idle" state. 904 to a “charging” state 908. In another example, the flow generator is turned on. When this happens, the battery switches from the "idle" state 904 to the "supply" state 906. obtain.

[0089] In some embodiments, the battery may switch to an “error” state 920 This error condition occurs when the battery is experiencing abnormal operating parameters (e.g. This can occur if the device detects abnormal operating parameters (such as excessive power being drawn). If a battery detects a power outage, it can, for example, suspend power output, shut down the internal rails, This may cause the battery to stop charging until the error is corrected. In some embodiments, the microcontroller may shut down or enter an "idle" state. The controller enables the battery to output information to a user and / or The device may accept a small amount of power to enable the device to detect whether the error condition has been corrected.
