DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0037] Detailed Description of the Preferred Embodiments of the Invention 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.

[0038] As mentioned above, the setting up of the treatment system requires multiple steps (such as repeating the process multiple times a day, or working a week) by a third party (e.g., HME provider or clinician) Therefore, for the person who sets it up, even a small improvement in efficiency is a It is extremely valuable.

[0039] By way of background, the breathing apparatus of the present technology (e.g., RPT devices) requires electrical power to operate. Typically, RPT devices require a variety of outputs (i.e. A power supply with a maximum power (e.g., about 20 to 120 W) is used. For AirSense® 10 devices from d Corporation, It operates on a 90 watt power supply (either from a power source or a battery). In some cases, smaller For powering a portable RPT device, a 20 watt power supply is sufficient. In some cases, a 65 watt power supply is used to power the RPT device. It is possible.

[0040] So for such a power supply, for example, a 100W DC converter is needed to convert the mains power to 90W DC power. May require AC / DC converters, which can typically be bulky and cumbersome Therefore, the provider may not use the power supply unit with the user's power supply unit solely for the purpose of performing the setup procedure. It may be necessary to remove the device from its packaging and then repackage it. It may be necessary to set power settings independently of the patient's device, e.g. A production run may require multiple sets of power supplies, and each of these multiple runs may require multiple This may not be desirable as product variations may exist.

[0041] Advantageously, the breathing apparatus of the present technology can be powered by different types of power sources that can provide different power levels. The breathing apparatus may be configured for use with different power connections. Such operating mode selection may be performed by input power circuits (e.g., Such an operating mode may be implemented with a detection circuit as described in more detail herein. Mode selection allows, for example, a user / healthcare equipment provider to quickly match a breathing device to a patient. Such an arrangement may be implemented to facilitate easy and convenient configuration. Low power levels are required for implementation (compared to the power required to deliver effective respiratory therapy) This is achieved by not having

[0042] For example, the connected power source must provide sufficient power to power the therapeutic operation of the RPT device. The RPT device is not configured to start therapy because the power is not sufficient to initiate therapy. The RPT device can be configured to be powered in a "low power mode" that allows for The device is responsible for detecting connected power from such an external source and for determining the operating mode and power and determining which subsystems should be powered on. In the example, the power supply is a universal serial bus that is insufficient to power all the components of the RPT. All components of the RPT or computing device (e.g., Enough to power a tablet computer, laptop or smartphone Dedicated modules (e.g., ResMed AirSense® 10 device) ResMed 90W power supply.

[0043] For example, a power supply designed to provide sufficient power for full operation (e.g., 90W supply) If power is detected, the RPT device may choose to operate in "therapy mode" and A power source that is not designed to be sufficient for operation (e.g., low-power 5 or 10 W available) If a fault condition is detected, the RPT may operate in a "low power mode."

[0044] In such a low power mode, the RPT device operates a first set of subsystems (e.g. , its controller(s) and memory, and in some cases, its The user can then power only the display and / or input / output devices. , one or more settings of the RPT device, for example by accessing the device's memory Or, operating parameters may be set or changed. can be achieved by using the RPT display / input device itself or by using an external device (e.g. For example, by implementing changes in the user interface of a tablet computer, In the latter case, the external device may be able to respond to the parameter change(s). The RPT's communication device and external devices (e.g. wired data connection or wireless device) The communication is made to the RPT via a data connection. Therefore, in low power mode, the controller will not (b) not initiate the operation(s) on the

[0045] For example, if a power source designed to be sufficient for such power operation is detected, it is selected. When operating in a selected therapy mode, the RPT device uses Required subsystems (e.g., pressure system, humidifier and heater(s)) For example, the heating tube) may be further powered on. Typically, a high power supply is connected If the device can provide power, it may operate / function in non-therapeutic (or low power) mode as well as in therapeutic mode. available in the device (e.g., access to the device's memory and Transfer of data to or from your device, data from your device (e.g. RPT by downloading doses, operations (e.g., errors, diagnostics) or other data Setting or changing one or more configuration or operating parameters of the device). The mode may be a data transfer mode or a data access mode.

[0046] Powers the RPT device when operating in a selected non-therapeutic (or low-power) mode. Simply connect it to a power transfer medium (e.g. USB cable, Lightning cable, Enables non-therapeutic operation with RPT devices through wireless protocols (e.g., Qi) It is possible.

[0047] Such low-power operation is particularly beneficial for clinicians from home medical equipment (HME) providers. These operations simplify the configuration of RPT devices without the need for a specific power supply. This operation allows for faster RPT for maintenance, for example. Downloading data from devices is also easier and faster, without the need for a specific power source For example, in the case of a hardware failure, the therapy component may not be activated at low power. This allows technicians to diagnose RPT devices without risking further damage to the device. For example, software can be transmitted over a low-power data cable without the need for a high-power power supply. Uploading may also allow for software upgrades of the RPT.

[0048] As described in more detail herein, in some versions, the connected The source detection may be realized through detection of the voltage of the connected power source.

[0072] RPT Device Electrical Parts 4200 RPT Devices One or more power supplies 4210 4C and 6 to 10, power from power supply 4210 (PS1) is typically Other components of the RPT device 4000 (e.g., input device 4220, A central controller 4230, a treatment device 4245, and an output device 4290, a heater The inputs are supplied to the data processor (singular or plural).

[0073] In one form of the present technology, the power supply 4210 powers the RPT device 4000 without a humidifier. In another embodiment of the present technology, power is supplied to the RPT device 4210 from a power source 4210. In yet another embodiment, the power supply 4210 is provided to both the power supply 4210 and the humidifier 5000. Power from the RPT device 4000, the humidifier 5000 and the air circuit 4170 is provided. The air circuit 4170 includes a heating element.

In another form of the present technology, the power supply 4210 is internal to the RPT device. The outer housing 4010 of the chair 4000 (sometimes referred to herein as the RPT) It's outside.

[0075] However, as shown in Figures 6-9, the RPT can be configured to operate with different power sources. For example, the RPT may be connected to two different power sources (e.g., fluctuating or different power outputs). The RPT may be configured to operate with two power sources with different power levels. The RPT may be configured to provide different operation in response to different power sources connected to it. In some versions, the operating mode of the device, as described in more detail herein, The controller controls the RPT according to the type (or power level) of power source attached to the RPT. The time may be determined by the controller or a processor.

[0076] For example, power supply 4210 (PS1) has a main power switching module that can block negative regenerative current. In some versions, the power supply 4210 may be rated to produce more than 20 watts. configured to provide a maximum power of approximately 20 to 120 watts The power source may be a high power source (e.g., an internal or external power source) that is connected to the , 100 watt power supply, 65 watt power supply or 20 watt power supply). In the present invention, such a power source may be used, for example, to provide a treatment using such a power source. For smaller, more portable RPT devices (which can be In some versions, such a device may be used for the treatment mode of the RPT device. A suitable power supply may be a 65 watt power supply. An external power supply may be, for example, a cable that connects the power supply to the RPT. The cable allows the RPT's interface 6711 (e.g. wireless for data and power) Wire-powered with wires or integrated data / power interface 6711B only The power supply 6711 may be plugged into a power interface 6711A having a power supply (single or multiple Optionally, the interface 6711 is a single interface, e.g. for power supply. other external power interfaces (connectors or ports) may be The RPT device is not provided with a T device operation. For example, the interface 6711 (e.g., USB interface (e.g., USB type C interface)) can function as a power and / or data interface. , for example, low power (e.g., less than about 20 watts (e.g., 5 watts)) or high It can receive power (e.g., power in the range of about 20 watts to 100 watts or more). An external power supply (or internal power supply) may also be plugged into the mains power outlet. , connect the cable to the mains outlet so that the AC input of the internal power supply is connected to the mains outlet. It can be plugged in and is more directly integrated with the RPT's power bus. Internal or external The external power supply is an AC / DC converter that converts the AC mains input to a DC output for powering the RPT. It may be a converter.

[0077] Such external or internal power supplies convert the power supply's input into an output DC signal (e.g., 12 volts, 24 volts or 30 volts), but preferably is approximately 24 volts. In some versions, the external power source is a DC / DC converter. (e.g., accepts 12 volt and / or 24 volt DC input and supplies this to the RPT (A converter capable of converting a 12 or 24 volt DC power signal for use in a 12V or 24V DC power supply.) Thus, the output DC power signal from the external power supply may be a 24 volt signal.

[0078] Such a power source may be connected to a blower motor (e.g., the treatment device controller 424 4245) including the power supply 4240 and any necessary sensor(s). For example, when providing a flow of pressurized breathable gas from a device, Providing sufficient power to operate the RPT in treatment mode(s); Thus, such a power source may be considered as a power source that produces high power. 5 includes humidification (e.g., humidity controller 5250 and heater 5240) and / or Other heater devices (e.g., tube heaters) may be optionally included. Typically, Such a high power supply is sufficient for powering all operations of the RPT as a system.

For example, the RPT may be It may be configured to connect to an alternative power source 4210-ALT (PS2) via an interface. Such alternative power sources may generate insufficient power to power all of the RPT's operations and may cause It may be considered a low or reduced power source because it is particularly inefficient at powering medical operations. Such external low power sources may range in power (e.g., from about 5 watts to 15 watts) (e.g., For example, the maximum power may be about 10 watts or 5 watts. In the embodiment, the output DC power signal from such a low power external power supply may be a 5 volt signal. Typically, such a low-power external power source provides power to the controller and memory (e.g., The power supply is sufficient to power the RPT's communication circuits (e.g., data communication In some cases, such low The external power source supplies power to one or more output devices 4290 (e.g., a display) and a RP It may also be sufficient to power one or more input devices 4220 (e.g., a keypad) of T. do.

[0080] A low-power external power supply may be used, for example, with a cable connecting the power supply to the RPT. 6711 (e.g., by connecting wires for data and power to the RPT) Wires (single or multiple) dedicated to power or integrated data / power interface 6711B In some such cases, In this case, the low power external power source may be configured similarly to the high power external power source (e.g., using the same cable). or coupler interface), so plug the former and latter into the same interface (e.g., either one at a time into a single interface 6711) (Can be plugged in at any time). Interface 6711 or integrated data / electricity The power interface 6711B is, for example, a Universal Serial Bus (USB) connector. It can be a port (e.g., Type A, Type B or Type C connector port, Micro USB connector connector port, Lightning connector port, or other suitable connector port). In some cases, such cable connections serve as power transfer conduits for RPTs. It can also function as a data transfer conduit / bus as well as a power supply. For example, Universal Serial Bus (USB) hubs, USB port power adapters, Management devices (e.g., desktop computers, laptop computers, tablets, computer) has a USB port. Therefore, connect it to a USB cable or a Lightning cable. The cable can be used to connect an RPT device and an alternative power source 4210-ALT.

Alternatively, the power supply 6711 may be connected to the power source 6711 via the wireless power interface 6711C shown in FIG. In such a case, the alternate power source 421 The 0-ALT may be a wireless power source. For example, such an interface may be electromagnetic induction. Power can be received by resonant inductive coupling, magnetic resonance, or inductive power transfer (IPT). In such cases, the interface may include a receiving coil and a receiving circuit. The transmit coil and receive circuit receive the magnetic field from the transmit coil of the alternative power source 4210-ALT. The transmitter coil generates DC power within the RPT by connecting the As described above, if an alternative power source is located near the RPT device 4211, Operated by an alternative power source so that it can function as a power source or a power saving source In some such versions, the Alternative Power Supply 4210-ALT may be In some versions, the coil is a planar Thus, the RPT may be configured with, for example, a pair of flat surfaces on the lower housing of the RPT. A receiving coil may be included, which may transmit power via a wireless alternative power source via a planar coil for power transfer. As mentioned above, such a wireless external power source can be configured, for example, by a controller (e.g. For example, it may be sufficient to power a memory (e.g., central controller 4230) and the RPT It may also power communication circuits (e.g., data communication interface 4280). A wireless external power source such as a It may also be optionally configured.

[0122] Input power circuit 6710 To accommodate the above mentioned different power sources, the RPT is The input power circuit 6710 typically includes a power supply (PS1 and / or 6711 for the PS2) (e.g., power interface 6711A, Data / Power Interface 6711B and / or Wireless Power Interface 67 11C). The input power circuit 6710 supplies power to one or more power sources in response to the power source. A circuit connector for receiving and routing some or all of the components of the RPT. For example, the circuitry 6710 may include a power routing component, such as a power level This can be done from a power supply 4210 via a power supply 4220, for example a high power supply (PS1 ) is connected to the RPT, the RPT's components (e.g., treatment generation components) ) It will be possible to power everything.

[0123] Circuit 6710 allows the use of an alternative power supply to power only a subset of the RPT's components. Power from the 4210-ALT (PS2) power supply can be connected to the RPT via the power rail. It is also possible to route to a subset of the components of a network. Such a subset is called an RPT. For example, a subset of components may include: Controller (e.g., Central Controller 4230 or other processor component of the RPT) Such a subset may be, for example, a wired connection for sending and receiving data to and from an RPT. A communication circuit (e.g., a communication interface 4280) for communication or wireless communication.

Components (e.g., therapeutic devices) are excluded (e.g., motor inverter bridges, etc. motors and / or therapy device controllers) and heating components (e.g. (e.g. humidifier heater, tube heater).

[0124] As shown in FIG. 9, in some cases, the input power circuit 6710 may include one or more detectors. The detection circuit 9002 may typically include a controller in the RPT (e.g., The detection circuit 9002 is connected to the input power circuit. For example, in some cases, the input The power circuit may include a voltage detector or voltage sensor circuit. The sensor is configured to detect a voltage associated with or specific to the power source connected to the RPT. Thus, the voltage detector detects the identification voltage generated by the connected power supply. For example, in the case of an exemplary 24 volt power supply (PS1) connection, The voltage detector detects a proportional voltage indicative of the 24 volt supply and produces a signal indicative of such voltage. The controller of the RPT (e.g., the central controller 4230) may (e.g., digital or analog input port) and extracts high power from this signal. In the case of a 5 volt power supply (PS2) connection, the voltage detector detects the 5 volt A proportional voltage indicative of the power supply may be sensed and a signal indicative of such voltage may be generated. A controller (e.g., central controller 4230) may then route this signal to the same or another input port. (e.g., a digital or analog input port) and The connection may be determined.

[0125] In one embodiment, the detector / sensor may be implemented with an operational amplifier. , configured as a comparator, and comparing the voltage associated with a power supply or input voltage with a different power supply (e.g. For example, a 6 volt threshold or a 7 volt threshold or other value) The output signal from the comparator is then compared to a suitable threshold voltage level. A power source may be indicated by an input to an input port of the controller 4230. For example, When a high (true) output signal is obtained from the comparator, this indicates that a voltage above the threshold (e.g., This indicates that a low voltage (higher than the low voltage of a power source, such as a power supply voltage) has been detected. Then, take such a (high true) output signal and use it as a digital input for a controller, for example. It is possible to indicate to the controller that a high-power power supply is connected at the port. The low output signal from the comparator represents a voltage lower than the threshold (e.g., lower than the high voltage of a high power supply voltage). Such a low (false) signal can then be used to, for example, This can be taken out at the input port to indicate to the controller that a low power supply is connected. A comparator can be used to generate a signal to the controller for such a decision. Any other suitable comparison may be implemented.

[0126] In some versions, the voltage detector / sensor detects the voltage of the connected power source (e.g., P Such a voltage can be generated proportional to the voltage supplied from the is sampled by the controller's sampler or sampling circuitry to obtain the controller's analog It may then be sampled at an input port (e.g., central controller 4230). The controller then compares the sampled values ​​with one or more programmed The power supply may be digitally compared to a threshold value to determine which power supply is connected.

[0127] In some versions, the input power circuit 6710 determines the detected power source type or One or more switching circuits 9 that actively route power based on the detected power level. Such a switch may also include a power / voltage rail for one or more of the RPTs and The RPT controller can be connected to, for example, a particular power supply to detect when it is connected to the Based on what the controller detects, the controller activates one or more switches. By selectively allowing power from a connected source through the voltage rails, the current can be controlled to a specific It can be supplied to a component or a subset of components in an RPT. Regarding the point, the output signal from the output port of the controller (e.g., digital output signal) activating one or more transistors (e.g., semiconductor type transistors) to generate a Power on the T rail(s) can be sent or initiated from a power source For example, one or more of these switches may allow an alternative power source to be connected to the RPT4000 interface. When connected to the 6711 interface, the supply line from the Alternate Power Supply 4210-ALT (PS2) This will prevent the power supply from being connected to the RPT treatment and / or heating device. Similarly, such one or more of such switches may cause the power supply to When connected to the interface 6711 at 0, the supply line from the power supply 4210 (PS1) Allows the ins to be connected to treatment and / or RPT heating devices do.

[0128] In some cases, the input power circuit 6710 may be a controller for an RPT (e.g., One or more voltage regulator modules (single or multiple) that may power the central controller 4230 Multiple) 9006 or VRM (PPM (Processor Power Module) (e.g., step-down Such a voltage regulator module (or modules) may include a The number of power supplies (PS1 and PS2) determines whether the component is powered by one or both of the power supplies. The input and / or input power circuit traces may be receptively connected.

In some versions, such a voltage regulator module or modules may be A display / splay driver (e.g., output device 4290) and an input device For purposes of illustrating the present technology, a simplified version of FIG. Although not shown, one or more of the voltage regulators may be powered by either or both sources. It will be appreciated that additional circuit components may be provided to enable this.

[0129] RPT Device Algorithm As described above, the central controller executes programs for carrying out the functions of the respiratory treatment device. The following exemplary process modules may be implemented with the algorithm: Any one or more of these may be included.

[0130] Operation Mode Detection Module 4309 As shown with reference to FIG. 10, a controller of the RPT (e.g., a central controller 42 30) is when the power supplies connected to the RPT are different (e.g. PS1 or PS2). The device may be configured to select different operation modes depending on whether the device is a Such mode selection is performed by the input power circuit 6710 (e.g., its detection circuit 9002 as described above). ) The execution of such an operation mode selection may be embodied by a controller in conjunction with: The user / healthcare equipment provider may choose to Quickly and easily set up a patient breathing device with a readily available power connection; Support downloading data, uploading software, etc. This can be done as follows.

[0131] For example, a controller of the RPT device 4000 (e.g., a central controller 4230 ) may embody a mode selection method as shown in the flow chart of FIG. The initial power supply to the controller is provided by, for example, the power supply (PS1) or the alternative power supply ( Optionally, RPT is started after power connection. A button may be provided on the RPT to turn it on. As mentioned above, this The input power supply 6710 may be powered by the voltage regulator module 9006 of the input power circuit 6710.

[0132] Next, at 10004, the controller may detect a power source connected to the RPT. For example, as described above, the controller may determine whether the power supply ( Such detection may be performed by a detection circuit 9002. Such detection may be performed by voltage detection (e.g., by a voltage detector / sensor). The comparison may be based on a comparison between a predetermined reference voltage and the sensed voltage. A power source is connected (e.g., sufficient power for therapeutic action) or a low-power power source is connected ( For example, it may function to determine whether there is insufficient power for therapy operation.

[0133] Thus, at 10006, the controller initiates a particular mode of operation based on the detection. For example, if a high power source is detected, the controller may initiate a therapy action (e.g., , a pre-processing module 4310 and a treatment engine module 4320 and a control module Similarly, the high power supply may be capable of detecting or performing the operations described above in connection with the control circuit 4330. If issued, the controller may (e.g. motor controllers and blower motors) and / or heating controllers and heating components (e.g., for humidifiers 5000 and heating tubes (singular or Such activation may result in the input power circuit for such components being turned on. This may include activating one or more switches in the switching circuit 9004 of the path 6710. The RPT controller detects available power from the external power source and and determining which of the subsystems to turn on. The decision as to which system or systems to turn on is based on a given set of subsystem priorities. The hierarchy may be based on the determined power output of the connected power sources.

[0134] If a low power source is detected, the controller may choose to disable non-therapy operations (e.g., certain high power therapy operations). Such low power devices may permit or perform certain operations (operations without the use of medical components). In the mode(s), the RPT device configures a first set of subsystems (e.g. , the controller(s) and memory and in some cases the data In such mode or modes, the The controller(s) may operate solely for data access (e.g., Download and upload operations (e.g. parameter settings, software updates) (Upgrade, diagnostic access). Such startups include low-power components such as Switching circuitry for the input power circuit 6710 for an input device (e.g., a display or input device) There is activation of one or more switches of 9004. Thus, the operating mode of the respiratory treatment device The board is powered by a Universal Serial Bus cable and Universal Serial Bus power supply.

[0217] IPAP: The desired mask pressure that the ventilator attempts to achieve during the inspiratory portion of the breath.

[0218] Pressure Support: A number indicating the increase in pressure during ventilator inhalation compared to the ventilator exhalation and mainly refers to the pressure difference between the maximum value during inspiration and the minimum value during expiration (e.g., P S=IPAP-EPAP). In some contexts, pressure support means This refers to the difference that the ventilator attempts to achieve (rather than the difference it actually achieves).

[0219] Servo ventilator: A ventilator that has both patient ventilation and target ventilation, and Adjust the level of pressure support to approach target ventilation.

[0220] Spontaneous / Timed (S / T): Attempts to detect the onset of breathing in spontaneously breathing patients , a mode of a ventilator or other device, but the device does not detect a breath for a period of time. If not, the device will automatically begin breath delivery.

[0221] Swing: A term equivalent to pressure assistance.

[0222] Trigger: When a ventilator delivers a breath of air to a spontaneously breathing patient, the patient begins to breathe. When the breath portion of the cycle begins, the ventilator is triggered to deliver a breath. He says.

[0223] Ventilator: A mechanical device that provides pressure support to a patient while performing some or all of the work of breathing. Vice.

[0224] Ventilator inhalation and ventilator exhalation: The ventilation that is appropriate for the patient's inhalation and exhalation, respectively.
