Background Art

[0003] (2) Description of Related Technology The respiratory system of the body facilitates gas exchange. The nose and mouth form the entrance to the patient's airway.

[0004] ] These airways include a series of branching tubes that become narrower, shorter, and more numerous as they progress deeper into the lungs. The main function of the lungs is gas exchange, taking oxygen from the air into the venous blood and expelling carbon dioxide. The trachea divides into the right and left main bronchi, which further divide and ultimately become the terminal bronchioles. The bronchi form the airways for conduction and are not involved in gas exchange. As the airways further divide, they become respiratory bronchioles and ultimately alveoli. The alveolar regions of the lungs where gas exchange occurs are the respiratory regions. It is called. See West's *Respiratory Physiology - Essential Elements*.

[0008] treatment method Numerous therapies (e.g., continuous positive airway pressure (CPAP), non-invasive ventilation (NIV), high-flow) High-frequency therapy (HFT) may be used to treat one or more respiratory diseases.

[0009] Patient Interface To supply air at positive pressure to the entrance of the patient's airway, use a nasal mask or a full-face mask. Alternatively, it is done using a patient interface such as a nasal pillow. A series of patient interfaces While such devices are known, many of them are particularly problematic when worn for extended periods or when the patient is using the system. If you are unfamiliar with it, it may be pushy, aesthetically undesirable, or have a poor fit. Experiencing one or more problems such as difficulty using or discomfort. Personal protective equipment Designed as part of a flight mask or anesthetic mask for pilots, it can withstand the original use, but even so, it can be uncomfortably unpleasant when worn for a long time, for example during sleep. There is.

[0010] RPT device Respiratory therapy devices such as positive airway pressure (PAP) devices or devices using a motor-driven blower Typically supply positive-pressure air or high-flow air to the patient's airway by a respiratory therapy device (RPT). As described above, the outlet of the blower is connected to the patient interface via a flexible delivery conduit. Connected.

[0011] Such devices can have a significant power requirement during the treatment operation using the device. For example, to power the motor of the treatment blower, usually a significant amount of power ( For example, power exceeding 20, 30 or 40 watts) may be required. In addition, for such devices, there may be accessory components that form a system for adjusting the comfort of the flow or pressurized air supplied from the flow generator. For example, the supplied Air may be attached to a humidifier that humidifies and heats the therapeutic gas before delivery of the therapeutic gas to the patient. The humidifier typically includes a heating element. Similarly, for the support of maintaining the supply gas at a specific temperature from the supply unit or humidifier while being conducted to the patient, Various heating elements can be connected to the delivery conduit. Even in such heating elements, for example, compared to the power requirements of a microcontroller or digital processor and the memory used in such devices, a significant amount of power is required. Overall, for the provision of treatment There may be accessory components that form a system for adjusting the comfort of the flow or pressurized air supplied from the flow generator. For example, the supplied Air may be added to a humidifier that humidifies and heats the therapeutic gas before delivery of the therapeutic gas to the patient. The humidifier typically includes a heating element. Similarly, for the support of maintaining the supply gas at a specific temperature from the supply unit or humidifier while being conducted to the patient, Various heating elements can be connected to the delivery conduit. Even in such heating elements, for example, compared to the power requirements of a microcontroller or digital processor and the memory used in such devices, a significant amount of power is required. Overall, for the provision of treatment From the supply unit or humidifier to maintain the supply gas at a specific temperature while being conducted to the patient, Various heating elements can be connected to the delivery conduit. In such heating elements as well, for example, compared to the power requirements of a microcontroller or digital processor and the memory used in such devices, a significant amount of power is required. Overall, for the provision of treatment A microcontroller or digital processor and the power requirements of the memory that can be used in such devices, a significant amount of power is required. Overall, for the provision of treatment A significant amount of power is required. Overall, for the provision of treatment For a treatment system, power in excess of 90 watts (e.g., power in excess of 110 watts or even in excess of 120 watts) may be required.

[0012] In some situations, a person other than the user of the treatment system may set the treatment system. For example, a clinician or a home medical equipment (HME) provider may prepare the treatment system using an initial setting for the user (e.g., the patient). In some situations, an HME may perform the initial setting multiple times (e.g., when making individual settings for multiple patients).

[0013] Therefore, if the setting simplification can be improved even slightly, it can be useful not only for the system patient but also for those who perform the setting multiple times, and the benefits are equally great.

[Figure 10] This flowchart illustrates an exemplary mode selection method, for example, for a controller, in several versions of this technology. [Modes for carrying out the invention]

[0037] Detailed description of the embodiments of this technology Before describing this technology in more detail, it should be noted that this technology differs from the differences described herein. It should be understood that this is not limited to any specific embodiment obtained. The terms used herein are for the purpose of describing specific embodiments described herein. It should also be understood that this is not limited to a specific area.

[0038] As mentioned above, the treatment system is set up so that (such a process is repeated multiple times a day, weekly work) (This can be done multiple times over time) by a third party (e.g., an HME provider or clinician) It is possible. Therefore, if the person performing the setup can improve efficiency even slightly, the provider Therefore, it is extremely valuable.

[0039] As background, the operation of the respiratory device (e.g., RPT device) of this technology requires power. Yes. Typically, to provide the power required for the RPT device, various outputs (i.e., A power supply with a maximum power output (for example, approximately 20-120W) is used. As an example, ResMe In the case of d company's AirSense (registered trademark) 10 device, (even from an AC outlet) It operates on a 90-watt power supply (or even from batteries). In some cases, a smaller size is required. Alternatively, for powering more portable RPT devices, a 20-watt power supply is sufficient. It is possible. In some cases, a 65-watt power supply is used to power RPT devices. It is possible.

[0040] Therefore, in the case of such a power supply, for example, in order to convert from main power to 90WDC power Because an AC / DC converter may be required, it can typically be bulky and cumbersome. Therefore, the provider will not leave the power supply unit with the user solely for the purpose of performing the setup procedure. In some cases, the equipment must be removed from its packaging, and then repackaged. It becomes necessary to configure power settings independently of the patient's device, for example, multiple devices. Multiple power supplies may be required in the manufacturing process, and each of these multiple manufacturing processes may require multiple This may be undesirable because product variations may exist.

[0041] Advantageously, the breathing apparatus of this technology utilizes different types of power sources that can provide different power levels. It can be configured to suit the use of the respiratory device. This respiratory device has different operating modes depending on the power connection. A mode can be selected and provided. Such operating mode selection is possible for the input power circuit (e.g., this This can be embodied with a detection circuit (as described in more detail in the specification). The selection process allows, for example, users / healthcare device providers to quickly tailor respiratory devices to patients. Furthermore, it can be implemented to support easy setup. Such a configuration can be set up In practice, only low power levels are needed (compared to the power required to provide effective respiratory therapy). It is achieved by its absence.

[0042] For example, if the connected power supply provides sufficient power to power the RPT device's therapeutic operation. Because it is not configured to do so, the RPT device is designed to have insufficient power to initiate treatment. It can be configured to be powered in a "low power mode" that enables constant power supply. The system detects power connected from such an external power source, and determines the operating mode and power supply. It can be configured to determine which subsystem should be powered on. In the example, the power supply is insufficient to power all components of the RPT, and the universal serial number All components or computing units of the RPT via a USB cable (for example, Sufficient to power a tablet computer, laptop, or smartphone. Dedicated modules (for example, ResMed AirSense® 10 devices) This could be a ResMed 90W power supply.

[0043] For example, designed to provide sufficient power for full operation (e.g., 90W supply). If power is detected, the RPT device may choose to operate in "treatment mode," and all Power supplies not designed to be sufficient for operation (e.g., low-power 5 or 10W available) If a sexually transmitted infection (SEX) is detected, the RPT may operate in "low power mode".

[0044] In such low-power modes, the RPT device comprises a first set of subsystems (for example). , its controller(s) and memory and in some cases It can only power the display and / or input / output devices. Then the user For example, by accessing the device's memory, one or more settings of the RPT device can be configured. Alternatively, you may be able to set or change the operating parameters. Such parameter changes This can be achieved by using the RPT display / input device itself, or by using an external device (e.g.) For example, by making changes to the user interface of a tablet computer, It may become possible. In the latter case, the external device will respond to parameter changes (one or multiple). Regarding RPT communication devices and external devices (e.g., wired data connection or wireless data connection) It communicates with the RPT via a data connection. Therefore, in low-power mode, the controller controls the therapeutic generation component (single). It does not initiate the action (singular or plural) of (or plural).

[0045] For example, if a power supply designed to be sufficient for such power operation is detected, it will be selected. When operating in a selected treatment mode, the RPT device is available for use in treatment or Required subsystems (e.g., pressure system, humidifier and heater(s)()) For example, the heating tube can be further powered on. Typically, a high-power power supply is connected. And, if power can be supplied, the operation / function of non-treatment (or low-power) mode will also be available in treatment mode. Available in (for example, access to the device's memory and said Transfer of data to or from a device, data from a device (for example, RPT (Recycled Processing) downloads include data on dosage, operation (e.g., errors, diagnostics), or other information. Setting or changing one or more device settings or operating parameters. Therefore, low power The mode can be either data transfer mode or data access mode.

[0046] When operating in the selected non-treatment (or low-power) mode, the RPT device is powered Simply connect it to a power transfer medium (for example, a USB cable, a Lightning cable, Non-therapeutic operations using RPT devices are enabled via wireless protocols (e.g., Qi). It is possible.

[0047] Such low-power operation is particularly advantageous for clinicians who are home healthcare equipment (HME) providers. This is possible. These actions simplify the configuration of RPT devices without requiring a specific power supply. Alternatively, it may enable faster operation. This type of operation, for example, allows for RPT (Remote Processing Tracking) for maintenance. Data downloads from devices can also be made easier and faster without the need for a specific power supply. It is possible. For example, in the case of a hardware failure, the repair component will start up with a low power supply. Therefore, technicians can diagnose RPT devices without the risk of further damage to the device. This is possible. For example, software can be transmitted via a low-power data cable that does not require a high-power power supply. Uploading may also allow for software upgrades to the RPT.

[0048] As described in more detail herein, in some versions, the connected electricity Source detection can be achieved through the detection of the voltage of the connected power supply.

[0072] RPT Device Electrical Components 4200 RPT device One or more power supplies 4210 Referring to Figures 4C and 6-10, the power from power supply 4210 (PS1) is typical. Other components of the RPT device 4000 (for example, input device 4220, Central controller 4230, treatment device 4245, and output device 4290, It is supplied to (singular or plural).

[0073] In one embodiment of this technology, the power supply 4210 powers the RPT device 4000 without a humidifier. To supply power. In another form of this technology, power is supplied from power supply 4210 to RPT device 4 It is provided for both the 000 and the humidifier 5000. In yet another form, the power supply 4210 Power from this source is supplied to the RPT device 4000, humidifier 5000, and air circuit 4170. The air circuit 4170 includes a heating element.

[0074] In one embodiment of this technology, the power supply 4210 is an external housing of the RPT device 4000. It is located inside 4010. In another form of this technology, power supply 4210 is RPT device External housing 4010 of chair 4000 (sometimes referred to as RPT in this specification) It is located outside.

[0075] However, as shown in Figures 6 to 9, the RPT is configured to operate with different power supplies. It is possible. For example, RPT can have two different power sources (e.g., fluctuating or different power outputs). It can be configured to operate with two power supplies (with different power levels). Furthermore, the RPT is It can be configured to provide different operation depending on the different power supply connected to the RPT. In some versions, as described in more detail herein, the operating mode of the device The RPT controls the RPT according to the type (or power level) of power supply attached to it. This can be determined by the roller or the processor.

[0076] For example, power supply 4210 (PS1) has a main power switching motor that can block negative regenerative current. It may include a power supply. In some versions, the 4210 power supply exceeds 20 watts. Configured to provide a certain amount of power (for example, a maximum power in the range of approximately 20 to 120 watts). It may be a high-power power supply (e.g., internal or external power supply) (e.g., a 90-watt power supply) (100-watt power supply, 65-watt power supply or 20-watt power supply). Therefore, several bars In John, such power sources are, for example, used to provide treatment using such power sources. For smaller, more portable RPT devices (which are capable of doing so), 20 watts is sufficient. It is possible. In some versions, this is the treatment mode for the RPT device. The power supply can be a 65-watt power supply. An external power supply is, for example, a power supply that connects to the RPT. The cable allows the RPT interface 6711 (for example, for data and power) to be used. Wireless for power or integrated data / power interface 6711B only. It can be plugged into a power interface 6711A) which has a (singular or plural) ya. Optionally, interface 6711 is a single interface for, for example, power supply. Because it may be a case of RP, other external power interfaces (connectors or ports) are RP It is not provided on the RPT device for T device operation. Uni, interface 6711 (for example, USB interface (for example, USB type The C interface can function as a power and / or data interface. For example, low power (for example, power lower than about 20 watts (for example, 5 watts)) or high It can accept power (for example, power in the range of approximately 20 watts to 100 watts or more). Next, external The internal power supply (or sub-power supply) can also be plugged into the main power outlet. Connect the AC input of the internal power supply to the main outlet using the cable. It can be plugged in and integrates more directly with the RPT's power bus. Internal or external The power supply unit converts the AC main input to a DC output for power supply to the RPT (Reverse Processing Unit) via an AC / DC converter. It could be a converter.

[0077] Such external or internal power supplies take power input and output DC signals (e.g., 12 volts, It can be configured to convert to 24 volts or 30 volts, but preferably to approximately 24 volts. It can be a bolt. In some versions, the external power supply is a DC / DC converter. To obtain (for example, by accepting a 12-volt and / or 24-volt DC input and converting it to RPT) A converter that can convert to a 12-volt or 24-volt DC power signal for use. Therefore, the DC power signal output from the external power supply can be a 24-volt signal.

[0078] Regarding such power supplies, the blower motor (for example, the treatment device controller 424) Power supply to the therapeutic device 4245) including 0 and any necessary sensors (one or more). This is especially true when, for example, a device is providing a flow of pressurized, breathable gas. In terms of being able to provide sufficient power for the operation of the RPT in one or more treatment modes, Therefore, such power supplies can be considered as power supplies that generate high power. (Therapeutic device 424) 5 is humidification (e.g., humidity controller 5250 and heater 5240) and / or Other heater devices (e.g., tube heaters) may optionally be included. Typically, Such a high-power power supply is sufficient for the entire RPT operation system.

[0079] However, in some versions, as described in more detail herein, other The power supply may be optionally used with the RPT of this technology. For example, the RPT is an inter It can be configured to connect to an alternative power supply 4210-ALT(PS2) via a faceplate. Such alternative power sources generate insufficient power to supply power to the entire operation of the RPT and the RPT's operation Because it is particularly insufficient in supplying power to therapeutic functions, it can be considered a low-power or energy-saving power supply. Such external low-power power supplies have a power range of (for example, about 5 watts to 15 watts) (for example) It can be configured to provide approximately 10 watts or a maximum power of 5 watts. Typical example In this case, the DC power signal output from such a low-power external power supply may be a 5-volt signal. Typically, such low-power external power supplies are used for the controller and memory (e.g., medium power supplies). It is sufficient to supply power to the central controller 4230, and the RPT communication circuit (for example, data communication) It can also supply power to the signal interface 4280). In some cases, such low External power supply provides power to one or more output devices 4290 (e.g., displays) and RP. It may also be sufficient to power one or more input devices 4220 of T (e.g., keypads). ru.

[0080] Low-power external power supplies are connected to the RPT via a cable, for example, an interface. It can be plugged into the Face 6711 (for example, the wires for RPT data and power). Wires dedicated to the power or integrated data / power interface 6711B (single) Power interface 6711A) has multiple (or more). In some such cases Low-power external power supplies can be configured similarly to high-power external power supplies (for example, using the same cable) (or coupler interface) Therefore, plug the former and the latter into the same interface. It can be connected (for example, to a single interface 6711 at different times) (Can be plugged in at any time). Interface 6711 or integrated data / electrical The 6711B interface is, for example, a Universal Serial Bus (USB) connector. It could be a port (for example, a Type A, Type B, or Type C connector port, or a micro USB connector) (Cata 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. An example of a low-power external power supply is... For example, a Universal Serial Bus (USB) hub, a USB port power adapter, and Computer devices (e.g., desktop computers, laptop computers, tablets) The computer has a USB port. Therefore, a USB cable or Lightning cable is needed. The cable can be used to connect the RPT device and the 4210-ALT alternative power supply.

[0081] In some versions, the RPT accepts wireless power via an interface. Alternative via -6711 (for example, the wireless power interface 6711C shown in Figure 8) It can be configured to connect to power supply 4210-ALT. In such a case, alternative power supply 421 0-ALT could be a wireless power source. For example, such an interface could be electromagnetic induction. It can receive power via 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 signal coil and receiving circuit receive the magnetic field from the transmission coil of the alternative power supply 4210-ALT. This generates DC power within the RPT. The transmission coil is an alternative power source interface. If it is located near S4211, the alternative power supply is low for RPT device 4000 as described above. Operated by an alternative power source, so that it can function as a power source or a power saving power source. It is possible. In some such versions, the alternative power supply 4210-ALT supports Qi It may be a power supply configured according to standards. In some versions, the coil is planar It may be in this form. Therefore, the RPT may be, for example, a set of planes on the lower housing of the RPT. It may have a receiving coil, which allows for wireless alternative power supply via a planar coil for power transfer. It can be configured. As mentioned above, such a wireless external power supply can be, for example, a controller (for example) If so, it may be sufficient to supply power to the memory (for example, the central controller 4230), and the RPT It can also supply power to the communication circuit (for example, the data communication interface 4280). However, A wireless external power supply like this is used to power the RPT's display and input devices. It can also be configured optionally.

[0082] In some configurations, the RPT device has multiple power supplies 42, for example, as shown in Figure 7. It can be configured to connect to 10 simultaneously (for example, power supplies 4210 (PS1) and 42 10-ALT(PS2)). In this configuration, the RPT device is one power It can be configured to prioritize one power source over another (for example, a power source capable of higher power) (If preferable).

[0083] Furthermore, the RPT device receives power from the first power source while also receiving power through the second power source. It can be configured to communicate with connected external devices. For example, an RPT device may be configured to communicate with high Power supply (e.g., main power switching mode) and low power supply (e.g., tablet power supply) It can be connected simultaneously (from a computer). In this configuration, the RPT device is It can be configured to receive power from a high-power source and communicate with a tablet computer. For example, while the RPT device is powered from a high-power source, the user can use a tablet computer. The setup procedure can be performed using a data entry tool. The RPT device, for example, when the high-power supply is disconnected. It can be further configured to initiate the reception of power from a low-power source.

To accommodate the reception of power from different power sources as described above, the RPT can include an input power circuit 6710. The input power circuit 6710 typically includes an interface 6711 for the power source (PS1 and / or PS2) (e.g., the power interface 6711A, the data / power interface 6711B, and / or the wireless power interface 6711C).

The input power circuit 6710 receives the power of one or more power sources according to the power source. Circuitry to allow some or all of the RPT components to receive and route It may include components. For example, circuit 6710 may configure power routing, for example, power rails. This can be done from the power supply 4210 via the wire, which allows for, for example, a high-power power supply (PS1 When the RPT is connected, the RPT components (for example, the treatment generation component) ) This will enable power supply to everything.

[0123] Circuit 6710 is used solely for supplying power to a subset of the RPT components. Power from the replacement power supply 4210-ALT(PS2) is supplied to the RPT via, for example, the power rail. Routes can also be configured to a subset of the Ponder. Such subsets are RPTs. These could be low-power components. For example, a subset of components would be: Controller (for example, the central controller 4230 or other processor components of the RPT) There are such subsets, for example, wired data transmission to and from RPT. Includes a communication circuit for communication or wireless communication (e.g., a communication interface 4280). Obtain. From such a subset, typically a treatment or therapeutic device and / or The higher power consumption of the RPT used in other operations involving heating components Components (e.g., medical devices) are excluded (e.g., motor inverter bridges) (G, motor and / or therapeutic device controller) and heating components (e.g.) (For example, a humidifier heater, or a tube heater.)

[0124] As shown in Figure 9, in some cases the input power circuit 6710 has one or more detectors It may include an output circuit. The detection circuit 9002 is typically a controller in the RPT (e.g., It is connected to the central controller 4230. The detection circuit 9002 is connected to the input power circuit. It can be configured to detect the type of power supply being used. For example, in some cases, the input The power circuit may include a voltage detector or voltage sensor circuit. The system is configured to detect voltages related to or specific to the power supply connected to the RPT. This can be achieved. Therefore, the voltage detector can identify the voltage generated by this connected power supply. The supply voltage can be detected. For example, in the case of connecting an exemplary 24-volt power supply (PS1), The voltage detector detects a proportional voltage indicating a 24-volt power supply and generates a signal indicating such a voltage. It is possible. The RPT controller (for example, the central controller 4230) has input ports. (For example, a digital or analog input port) receives this signal and high-power electricity The power source connection can be determined. If a 5-volt power supply (PS2) is connected, the voltage detector will be 5 volts. It is possible to detect a proportional voltage indicating the power supply and generate a signal indicating such a voltage. RPT control The roller (for example, the central controller 4230) receives this signal from the same or a different input port. (For example, a digital or analog input port) is received, and this signal is converted to a low power supply. The connection can be determined.

[0125] In one embodiment, the detector / sensor may be implemented together with an operational amplifier. , configured as a comparator, and compares the voltage associated with the power supply or input voltage with a different power supply (e.g.) For example, an appropriate one selected to distinguish between a 6-volt threshold, a 7-volt threshold, or other values. The output signal from the comparator is then compared to the threshold voltage level. Next, the output signal from the comparator is connected to the controller or central Power can be indicated by inputting it to the input port of controller 4230. For example, If a high (true) output signal is obtained from the comparator, this indicates that the voltage exceeds the threshold (for example, high This indicates that a voltage higher than the low voltage of a low power supply, such as the power supply voltage, has been detected. This (high true) output signal can then be taken and used, for example, as a digital input for a controller. The port can indicate that a high-power supply has been connected to the controller. A low output signal from the comparator is a voltage lower than the threshold (for example, a high voltage from a high-power supply). This can indicate a low voltage. Next, such a low (false) signal can be used, for example, in the digital of a controller. The input port can be used to indicate to the controller that a low-power power supply has been connected. Yes, it is possible. To generate a signal for the controller for such a decision, a comparator is used. Other appropriate comparisons used are also implementable.

[0126] In some versions, the voltage detector / sensor is connected to a power supply (e.g., P A voltage proportional to the voltage supplied from S1 or PS2 can be generated. The controller's analog signal is generated by the controller's sampler or sampling circuit. The input port (for example, the central controller 4230) may be sampled. The controller takes the sampled value and one or more programmed values ​​of the controller. By digitally comparing it with a threshold value, it is possible to determine which power supply is connected.

[0127] In some versions, the input power circuit 6710 detects the power supply type or One or more switching circuits 9 that actively route power based on the detected power level. 004 may also be included. Such a switch has one or more power / voltage rails of the RPT and It can be connected to the RPT controller. For example, if a specific power supply is connected to the detection circuit. Based on the controller's detection, the controller activates one or more switches. Then, it selectively allows power from the connected power supply through the voltage rail, and the current is specific It can be supplied to a component or a subset of components of an RPT. Regarding this point, the output signal from the controller's output port (for example, a digital output signal) This activates one or more transistors (e.g., semiconductor transistors), RP Power can be supplied from a power source or initiated on one or more rails of a T. For example, one or more of these switches can provide an alternative power supply to the RPT4000 interface. When connected to face 6711, the power supply from the alternative power supply 4210-ALT(PS2) This can prevent the connection to the RPT treatment and / or heating device. Similarly, one or more of these switches can power the RPT400 When connected to interface 6711, power supply from 4210 (PS1) It is possible that the input may be connected to the heating device for treatment and / or RPT. ru.

[0128] In some cases, the input power circuit 6710 is the controller of the RPT (for example, One or more voltage regulator modules (single or) that can supply power to the central controller 4230. (Multiple) 9006 or VRM (PPM (Processor Power Module) (e.g., step-down type) This may include voltage regulator modules (also called converters). The number of components receives power from either or both of the power sources (PS1 and PS2). It can be connected so that the traces of the input power circuit and / or input power circuit can be accepted. The voltage regulator module (one or more) controls the controller and other low-voltage components of the RPT. It may be connected to a power component. Therefore, the voltage regulator is powered by power supply 4210 or alternative Regardless of whether power supply 4210-ALT is connected to or linked to RPT4000, A controller (e.g., central controller 4230) and optionally a communication circuit (e.g., It can supply power to the data communication interface 4280). Optionally, several In that version, such voltage regulator modules (one or more) are, Display / display driver (e.g., output device 4290) and input device It can also supply power to the 4220. For illustrative purposes of this technology, a simplified version is shown in Figure 9. Although not shown, power is supplied to one or more of the voltage regulators by either or both power sources. It is understood that additional circuit components may be provided to make this possible.

[0129] RPT Device Algorithm As mentioned above, the central controller is the professional responsible for performing the functions of the respiratory therapy device. In Seth, it can be implemented together with the algorithm. The following example process module Any one or more of these may be included.

[0130] Operating mode detection module 4309 As shown with reference to Figure 10, the RPT controller (e.g., central controller 42) 30) The power supply connected to the RPT is a different power supply (for example, PS1 or PS2). It can be configured so that different operating modes can be selected depending on which one it is. Mode selection is performed by the input power circuit 6710 (for example, the detection circuit 9002 as described above). ) can be embodied by the controller in relation to this. The execution of such operation mode selection is Users / healthcare device providers (in "low power mode" which excludes therapeutic operations) To quickly and easily configure patient respiratory devices using readily available power connections, It helps with things like downloading data and uploading software. Yes, it can be done.

[0131] For example, the controller of RPT device 4000 (for example, the central controller 4230) ) can embody the mode selection method shown in the flowchart of Figure 10. Regarding this point, Initial power supply to the controller is, for example, via power supply (PS1) or alternative power supply ( This can be done by connecting either PS2 or another device. Optionally, start the RPT after connecting the power. A button may be provided on the RPT to (turn it on). As mentioned above, this is The power circuit 6710 can be powered by the voltage regulator module 9006.

[0132] Next, in 10004, the controller may detect the power supply connected to the RPT. For example, as mentioned above, the controller detects the type of power level, for example, to control the power supply. It may detect 4210 or 4210-ALT). Such detection is performed by detection circuit 9002 This can be done by voltage detection using (for example, a voltage detector / sensor). Such detection is This can be based on a comparison between a predetermined reference voltage and the sensed voltage. Such a comparison is high power Power is connected (for example, sufficient power for the treatment operation) or low-power power is connected. For example, it could function to identify if the power supply is insufficient for the therapeutic action.

[0133] Therefore, in 10006, the controller triggers based on the detection of a specific operating mode. It can be activated. For example, if a high-power supply is detected, the controller will perform a therapeutic action (e.g., , pre-processing module 4310 and treatment engine module 4320 and control module The operation described in relation to 4330 may be permitted or performed. Similarly, high-power power supplies may be detected. If issued, the controller will control the therapeutic component (e.g., therapeutic device 4245). (For example, motor controllers and blower motors) and / or heating controllers and heating components (e.g., those for humidifier 5000 and heating tubes (single or Multiple activations may occur. Such activations may trigger input power cycles for such components. This may include activating one or more switches in the switching circuit 9004 of path 6710. The RPT controller detects available power from an external power source and its subsystem It can be configured to determine which of the stems to turn on. The decision of which of the systems (single or multiple) to turn on is determined by the subsystem priority. This can be determined based on the hierarchy and the power output of the connected power supply.

[0134] If a low power supply is detected, the controller will perform non-therapeutic actions (e.g., certain high-power therapeutic actions). Operation without the use of medical components may be permitted or allowed. In each mode (one or more), the RPT device comprises a first set of subsystems (e.g., , controller(s) and memory and in some cases its data It is possible to supply power only to the display. In such modes (single or multiple), A controller (singular or plural) can only operate for data access (for example, Download and upload operations (e.g., parameter setting, software update) Grade, diagnostic access). Examples of such startups include low-power components. Switching circuit for input power circuit 6710 for input (e.g., display or input device) There is activation of one or more switches on the 9004. Therefore, the operating mode of the respiratory therapy device The system uses a universal serial bus cable and a universal serial bus power supply. Power can be supplied, and the operating mode is to access data or memory of the respiratory therapy device. This may include. Alternatively, the operating mode of a respiratory therapy device may use a wireless power transmission device. Power can be supplied, and the operating mode is to access data or memory of the respiratory therapy device. It can encompass.

[0135] In such low-power operating modes, the user then uses, for example, the built-in display. For data communication (wired or wireless) with the RPT device 4000, the RPT device RPT data can be accessed through an external device connected to the chair (e.g., a tablet computer). This allows you to change one or more settings on the device or access data on the RPT device. It is possible.

[0136] Preprocessing module 4310 Refer to Figure 4D, for example, the treatment mode is activated based on the operating mode detection module. After this, the pre-processing module 4310 using this technology processes the converter (for example, the pressure converter 42 Receive raw data from 72 or flow converter 4274 as input, preferably one or more Perform one or more process steps to calculate the above output values. These output values ​​are separate It is used as an input to the module (for example, the treatment engine module 4320).

[0137] In one embodiment of this technology, the output values ​​are the interface or mask pressure Pm and the breathing flow. Includes volume Qr and leakage flow rate Ql.

[0138] In various forms of this technology, the preprocessing module 4310 uses the following algorithms: Includes one or more of the following: pressure compensation algorithm 4312, airflow algorithm 4314, Leakage flow algorithm 4316, breathing flow algorithm 4318, and jamming detection Algorithm 4319.

[0139] Pressure compensation In one embodiment of this technology, the pressure compensation algorithm 4312 (shown in Figure 4D) is used for air pressure The system receives a signal as input indicating the pressure in the pneumatic path near the block outlet.

[0141] Leakage flow In one embodiment of this technology, the leakage flow rate algorithm 4316 (shown in Figure 4D) is the total flow rate It receives Qt and airflow rate Qv as input and is long enough to include a large number of respiratory cycles.

[0142] In one embodiment, the leakage flow rate algorithm 4316 provides the leakage flow rate Ql as an output. , calculate the leakage conductance and the leakage flow rate Ql using the leakage conductance and i By determining that it is a function of the interface pressure Pm, the patient interface The total flow rate Qt, airflow rate Qv, and estimated pressure Pm of 3000 are received as input. In the concrete example, the leakage conductance is the low-pass filtered non-permeable flow rate Qv-Qt The quotient is calculated as the low-pass filtered square root of the mask pressure Pm, and the low-pass filter The Ruta time constant has a sufficient value to include several respiratory cycles (e.g., about 10 seconds). do.

[0143] Breathing flow In one embodiment of this technology, the respiratory flow algorithm 4318 uses the total flow rate Qt and the airflow rate Q. It receives v and leakage flow rate Ql as input, and converts the aeration flow rate Qv and leakage flow rate Ql to the total flow rate Q By subtracting from t, the respiratory flow rate Qr to the patient is estimated.

[0144] Jamming detection The leak has recently been modified, and the leak flow algorithm 4316 is now fully compensated for this change. If this is not the case, a state called "jamming" exists. This "jamming" state is U.S. Patent No. 6,532,957, U.S. Patent No. 6,810,876 or U.S. Patent Publication No. This can be determined based on the method described in Application Publication No. 2010 / 0101574A1. In this book, the same document is referenced. In a jamming state, the respiratory flow baseline is It is common for there to be some degree of inaccuracy, in which case the distortion of the flow shape and the limitations of flow detection become apparent. This can cause an impact. Jamming is used to indicate the extent of uncompensated leakage. This can be done and calculated by the jamming detection algorithm 4319 (shown in Figure 4D).

[0145] Treatment engine module 4320 In one embodiment of this technology, the treatment engine module 4320 (shown in Figure 4D) is used by patients The pressure Pm in interface 3000, the air breathing flow rate to the patient Qr, the leakage flow rate Ql, and the jerk. It receives one or more of the jamming variables as input and outputs one or more treatment parameters. We will provide it.

[0146] In some versions of this technology, the treatment parameter is CPAP treatment pressure Pt. This is a two-level pressure therapy.

[0147] In one form of this technology, the treatment parameters are the level of pressure support and the target ventilation bladder. There is one or more.

[0148] Phase determination In one embodiment of this technology, the RPT device 4000 does not determine the phase.

[0149] In one form of this technology, the phase determination algorithm 4321 (shown in Figure 4D) is called The system receives a signal indicating the inspiratory flow rate (Qr) as input and calculates the phase of the respiratory cycle for 1000 patients. Provides a constant (Φ). The rate of phase change is indicated by the respiratory rate.

[0150] Waveform determination In one embodiment of this technology, the treatment control module 4330 controls the treatment device 4245. This provides a nearly constant positive airway pressure throughout the patient's respiratory cycle.

[0151] In one embodiment of this technology, the treatment control module 4330 controls a predetermined pressure waveform for each phase. The treatment device 4245 is controlled to obtain positive airway pressure accordingly. The waveform is maintained at a nearly constant level across the entire phase. In one form, the waveform is rectangular. It is a wave, with the value being higher at some values ​​in the phase and lower at other values ​​in the phase. In some cases, the treatment device is controlled to deliver high-flow therapy. It is possible.

[0152] In one form of this technology, the waveform determination algorithm 4322 (shown in Figure 4D) is currently It receives a value indicating patient ventilation (Vent) as input and provides a pressure-to-phase waveform as output. do.

[0153] In one form, the waveform is a square wave, and the value is 1 in the early value of the phase corresponding to intake. Furthermore, the value is 0 in the later phase of the phase corresponding to exhalation. In other forms, the waveform is more The waveform is "smooth and pleasant," gradually rising to 1 in the early phase and increasing to 1 in the later phase. It gradually decreases to 0.

[0154] Ventilation decision In one embodiment of this technology, the ventilation decision algorithm 4323 (shown in Figure 4D) determines the respiratory flow The system receives a volume Qr as input and determines the measurement that indicates patient ventilation (Vent).

[0155] In one form, the ventilation decision algorithm 4323 loads the current value of patient ventilation, Vent. It is determined as half of the pass-filtered absolute respiratory flow value Qr.

[0161] EPAP decision In one form of this technology, where multiple different characteristics of upper airway obstruction ("UAO") exist... In total, if EPAP exceeds the preset minimum value, minimum EPAP, then the upper It rises to a degree that is largely proportional to the severity of airway obstruction. If there are no features indicating UAO, E PAP gradually decreases to a pre-set minimum EPAP. This decrease is It tends to minimize the delivered EPAP. At any given time, EPAP is It is a balance between the force that increases EPAP and the force that decreases EPAP. When near equilibrium is reached, EPAP will be affected by the occasional indicators of moderate UAO. It moves upward, and this upward movement is due to the decline that occurs when there is no UAO indicator. Equilibrium is achieved.

[0162] When the EPAP adjustment algorithm 4327 (shown in Figure 4D) specifies an increase in EPAP This increase cannot occur instantaneously. Such an increase in EPAP is due to the central controller 4 The period during which the RPT device 4000 is thought to be in an intake state may be controlled by 230. The timing is set so that it occurs precisely. An example of such technology is published in a U.S. patent application. Disclosure is made in 2011 / 0203588A1. This specification references to that document for informational purposes. do.

[0163] Determination of target ventilation of 4328 In some cases, target ventilation is a percentage of typical recent ventilation. For example, it can be set to 90%). Typical modern ventilation has a time constant of 3 minutes (ventilation fee). The formula (Luta) is applied to instantaneous ventilation and calculated as the output of a one-dimensional low-pass filter.

[0164] Determination of treatment parameters The central controller 4230 uses one or more algorithms for determining treatment parameters. Execute step 4329 (shown in Figure 4D).

[0165] Control module 4330 A therapeutic control module 4330, in one form of this technology, receives the target therapeutic pressure Pt as input. The device receives the signal and controls the treatment device 4245 to deliver the pressure.

It receives target ventilation and instantaneous ventilation as input, and provides pressure assistance from target ventilation and instantaneous ventilation. The level is calculated, and the target therapeutic pressure Pt is measured using EPAP, waveform values, and pressure assistance. The system calculates and controls the treatment device 4245 to deliver this pressure.

[0168] Detection of fault conditions In one embodiment of this technology, the central controller 4230 is one for detecting a fault condition The above methods can be performed. The fault conditions detected by one or more methods are among the following, with the fewest being... It may include at least one: ● Power outage (no power or insufficient power) ● Detection of converter failure ● Component cannot be detected ● Operating parameters are outside the recommended range (e.g., pressure, flow rate, temperature, PaO2). 2) ● Failure to perform test warnings to generate detectable warning signals.

[0169] When a fault condition is detected, the corresponding algorithm signal will be one or more of the following: Signaling the presence of a malfunction: ● Initiation of audible, visual, and / or dynamic (e.g., vibrational) warnings ● Sending messages to external devices ● Incident logging

[0170] According to another aspect of this technology, the central controller 4230 has software that detects fault conditions. The wear module can be omitted. Rather, as mentioned above, the detection of the fault condition can be handled by a central control. Roller 4230 and other fault mitigation integrated circuits can handle this exclusively. In that case, the fault mitigation integrated circuit is similarly processed within the central controller. It functions as a redundant backup for fault detection / mitigation modules equipped with algorithms. obtain.

[0173] humidifier 5000 In one embodiment of this technology, a humidifier 5000 (Figure 5) includes a water reservoir and a heating plate. (To be shown) is provided.

[0174] Example usage of RPT devices (single or multiple) Next, the exemplary apparatus implementation described herein can be used, for example, for device configuration or diagnosis. Relatedly, improved RPT device operation can be obtained. For example, a user can use a tablet. Connecting to a computer or similar RPT device is done via, for example, a USB cable. Therefore, if power is obtained only from the tablet, the RPT device can (using the USB power supply of the tablet) A tablet cable that provides power to the RPT device It can operate via a cable. This cable uses, for example, a USB-C connector. This allows connection to a single power interface (port) of the RPT device. RPT devices offer low-power or high-power options in a single power interface (interface) - Can it be obtained via the power lines (one or more) / pins (one or more) of the face? It detects this power and operates according to this power detection in the selected mode. (For tablets) RPT devices typically detect low-power modes. In low-power mode, RP T devices have a single power interface (data line of the interface (single (via one or more) / PINs (one or more) to communicate data with the tablet, For example, upload RPT device, patient settings, and RPT device configuration data to a tablet. Either load or store tablet error logs, usage logs, or diagnostic data on the RPT device. It can be downloaded to [platform name]. Currently, USB-C cables are 5 watts (low power mode). It can provide up to 100 watts (high power mode). Therefore, the same type Even when connecting a cable to a single power port / interface, for example, if a tablet is connected When deactivated, it connects to a single interface from a suitable, higher-power power source. Power can be obtained. Therefore, the RPT device uses the same cable coupler and interface. - Along with the face configuration, it can operate in high-power modes that can exceed 20 watts. In the case of a CPAP-type RPT device, 100 watts may be sufficient to provide treatment, but R The PT device can also provide therapeutic operation at approximately 65 watts or approximately 90 watts. The power consumption of an RPT device is typically measured by the number of sleep disturbance respiratory events detected (e.g., The treatment pressure provided depends on the apnea / hypopnea index. Pressure RPT devices are used. You must avoid events like these and the humidity generated from humidifiers. Humidifier or The humidity generated depends on the ambient humidity and temperature (in the case of cold air, much higher humidification is required). (may depend on) the power supply for high-flow therapeutic RPT devices, up to 300 watts. This may become necessary.

[0175] As described above, the RPT device connects each different power supply to the RPT device at different times. When connected, it is configured to connect to multiple power sources via a single power interface. Therefore, different power supplies typically have a single power interface. Connected to one of these power supplies via a face or a single power interface To connect to other power sources via (i.e., the same port), (at different times) They can be used sequentially. Alternatively, more than one power supply can be used in a single power interface. You can connect them in parallel simultaneously, or you can use a dual interface to connect them in parallel simultaneously. They can be connected, and the logical controller is used to decide which one to use. It is possible. For example, a computing device (e.g., a tablet) can use a USB cable. It can be connected to the RPT device via a single interface with the . High power computing equipment To enable the RPT to receive data via the same USB cable through the device, the computing device (for example, The tablet may be connected to a high-power power supply (e.g., the main power supply). Then the controller This determines the possible operations given that a given power is available from a single interface. Similarly, the cable from the high-power power supply to the first input of the dual interface (e.g., For example, it can be connected to power and / or data, and at the same time, from a low-power power source. Connect another cable to the second input of the dual interface (e.g., power and / or data). It can be connected to a power source (e.g., a power supply). Therefore, as mentioned above, it can be connected to more than one power source (e.g., a power supply). For example, connecting both power sources to a power interface (one or more) simultaneously. To enable this, implement the power interface as multiple power interfaces. This is possible. Next, the controller of the RPT device provides based on the detection circuit described above. Possible operations can be determined. These available operations depend on at least one of the connected power supplies.
