The breathing circuit 200 may include a tube 202 that may be coupled to the medical device apparatus 102 at a first end 204 and to the patient interface 300 at a second end 206.

[0020]

[0029] In some embodiments, the medical device apparatus 102 may be a ventilator used to provide assistance to a patient having difficulty breathing. The medical device apparatus 102 may be configured to provide different modes of ventilation to the patient. For example, the medical device apparatus 102 may be The medical device apparatus 102 may be configured to provide assist-controlled ventilation, volume-controlled mandatory ventilation, pressure support, pressure-controlled mandatory ventilation, pressure-controlled volume-controlled, positive end-expiratory pressure, synchronized intermittent mandatory ventilation, and / or manual ventilation. The medical device apparatus 102 may be used in place of a bag-valve device, an ambulance ventilator, or any other mode or device for providing ventilation to a patient.

[0021]

[0030] 1-4, the medical device apparatus 102 may include a housing 132, a blower 104, a control system 106, and a power source 108. The housing 132 of the medical device apparatus 102 may house and protect the components disposed within the medical device apparatus 102. The housing 132 may be lightweight to allow for easy portability of the medical device apparatus 102. For example, the housing 132 of the medical device apparatus 102 may be made of a lightweight polymer to allow for easy transportation. In some embodiments, the housing 132 is made of one or more of acrylonitrile butadiene styrene (ABS), polyoxymethylene (POM), aliphatic polyamide (PPA), polycarbonate (PC), polyphenylsulfone (PPSU), polyetherimide (PEI), and polypropylene (PP). The housing 132 may be made of a lightweight yet durable material to allow repeated use in harsh environments while still providing portability. For example, the housing 132 may be made of ABS to provide portability and to ensure that components disposed within the housing 132 remain secured, protected, and undamaged. In some embodiments, the housing 132 of the medical device apparatus 102 is generally rectangular in shape to allow for easy storage. However, the housing 132 may be square, circular, triangular, octagonal, or any other shape desired. In some embodiments, the housing 132 includes side walls 130. In a preferred embodiment, the housing 132 includes four side walls 130 to define the generally rectangular shape of the medical device apparatus 102. In some embodiments, the housing 132 has rounded corners and beveled edges to allow for a more ergonomic shape.

[0022]

[0031] 2-3, the housing 132 may include a top surface 122 and a bottom surface 139. In some embodiments, the top surface 122 is parallel to the bottom surface 139. The top surface 122 may be coupled to the bottom surface 139 via a sidewall 130. The housing 132 may include a cutout 120 disposed on the top surface 122 of the housing 132. The cutout 120 may be sized and shaped to receive a user interface 124. The user interface 124 may be a display device that may be disposed within the cutout 120 and may be configured to receive input from a user. In some embodiments, the user interface 124 is a graphical user interface. For example, the user interface 124 may be a touch screen configured to receive input from a user and transmit the input to the control system 106. Additionally, the user interface 124 may be used to display information about a patient using the medical device apparatus 102. For example, the user interface 124 may display a representation of a patient's respiratory status that is coupled to the patient interface 300. In some embodiments, the user interface 124 may display various settings, parameters, and / or functionality of components disposed within the medical device apparatus 102. For example, the user interface 124 may display a maximum inspiratory pressure (PIP), a tidal volume (TV), a respiratory rate (RR), a positive end-expiratory pressure (PEEP), an inhalation-to-exhalation ratio (I:E ratio), a ventilation mode, a maximum flow rate, and a sensitivity. The user interface 124 may be coupled to the control system 106 and configured to control various components of the system 100. For example, a user may interact with the user interface 124 to change parameters of the blower 104. In some embodiments, the user interface 124 is configured to display instructions to the user. For example, the user interface 124 may display instructions to the medical device apparatus 102. The user interface 124 may provide instructions to the user for correcting errors on the medical device apparatus 102. In some embodiments, the user interface 124 is configured to display animations or graphics to the user to instruct the user on how to correct or resolve errors on the medical device apparatus 102.

[0023]

[0032] In some embodiments, a user interacts with the user interface 124 to change various modes and / or parameters of the medical device apparatus 102. For example, the user interface 124 may provide options for adjusting PEEP, PIP, tidal volume, I:E ratio, or other parameters. In some embodiments, the medical device apparatus 102 includes a beacon or indicator 134 to provide a status of the system 100. The indicator 134 may provide a status of the system 100 and / or the medical device apparatus 102. For example, the indicator 134 may indicate whether the medical device apparatus 102 is damaged, inoperable, and / or functionally adequate. The indicator 134 may be an LED, and the control system 106 may transmit a status to the indicator 134, causing the indicator 134 to illuminate a particular color and flash at a particular frequency. However, the indicator 134 may also be a transmitter configured to transmit an outgoing signal. In some embodiments, the indicator 134 is configured to continuously transmit an outgoing signal regarding the status of the medical device apparatus 102. For example, the indicator 134 may be configured to continuously transmit a signal without being prompted to do so. The indicator 134 may transmit a signal indicating that all components of the medical device apparatus 102 are functioning properly. In some embodiments, the indicator 134 transmits a signal continuously until an error occurs that disrupts the signal transmission and results in the indicator 134 no longer transmitting a signal. A user may check the receiver to determine whether the indicator 134 is transmitting a signal and whether an error has occurred based on the ceased transmission. In other embodiments, the indicator 134 is configured to transmit a first signal when the medical device apparatus 102 is functioning properly without significant errors and a second signal when an error occurs. The first signal may be different from the second signal.The indicator 134 may transmit signals wirelessly via radio frequency, WiFi, cellular signals, Bluetooth, near field communication, or any other type of wireless modality.

[0024]

[0033] In some embodiments, the indicator 134 provides the status of the medical device apparatus 102 without the user having to interact with or power it on. For example, the indicator 134 may be coupled to a power source separate from the power source 108 and configured to illuminate to provide an indication of the status to a user without the user having to interact with the medical device apparatus 102. The indicator 134 may transmit a signal to an external receiving device. In some embodiments, the indicator 134 transmits a signal regardless of whether the external receiving device is in proximity to the medical device apparatus 102 or whether the external receiving device has requested data from the indicator 134. For example, the indicator 134 may be configured to transmit a signal regardless of whether the device is listening or has requested a signal from the indicator 134. In some embodiments, the indicator 134 is configured to always transmit a signal when the medical device apparatus 102 is functioning or operating properly.

[0025]

[0034] In practice, the control system 106 may perform a self-diagnosis or status check without user intervention and cause the indicator 134 to illuminate based on the results of the self-diagnosis or status check. The user may view the medical device apparatus 102 and the indicator 134 after the self-diagnosis or status check has been performed. When viewing the indicators 134, the user may be able to determine the status of the medical device device 102 and whether there are any errors associated with the medical device device 102 without having to interact with the medical device device 102. Interacting with the medical device device 102 may include activating one or more buttons on the medical device device 102, powering on the medical device device 102, or engaging with the user interface 124. In practice, the user may view the indicators 134 immediately after a self-diagnosis or status check is performed, or may view the indicators 134 after a period of time has passed since the self-diagnosis or status check was performed. In some embodiments, the control system 106 is configured to send a signal to the indicators 134 regardless of the power status of the medical device device 102. In other words, the indicators 134 may be configured to always receive a signal from the control system 106 regardless of the power status of the medical device device 102. This may be due to the control system 106 and the indicator 134 each having their own power source separate from the power source 108, or the control system 106 and the indicator 134 sharing a power source separate from the power source 108. In some embodiments, the indicator 134 has a low power sensor configured to receive a signal from the control system 106 to illuminate based on the status of a self-diagnostic or status check performed.

[0026]

[0035] In some embodiments, the indicator 134 is configured to flash different colors of light. For example, the indicator 134 may flash green when the medical device apparatus 102 is operating normally, may flash red when the medical device apparatus 102 is not operating normally, or may flash yellow when the medical device apparatus 102 has an error but can still function. However, the indicator 134 may flash or have a constant illumination. The indicator 134 may be any color desired and may alternate between different colors depending on the status of the medical device apparatus 102. In some embodiments, the indicator 134 is coupled to a power source to ensure that the indicator 134 can continuously provide an indication for the status of the medical device apparatus 102.

[0027]

[0036] In some embodiments, the housing 132 also includes an indicator 133. The indicator 133 may be similar to the indicator 134. The indicator 133 may also indicate the status of the medical device apparatus 102 and may be used to provide an alert to the user regarding an alarm condition. For example, the indicator 133 being green may indicate normal operation of the medical device apparatus 102. However, the indicator 133 flashing amber, red, yellow, or orange may indicate a malfunction or error in the medical device apparatus 102. In some embodiments, the degree of flashing of the indicator 133 indicates the severity of the error. The indicator 134 may also indicate a battery status associated with the power source 108. For example, the indicator 134 being green may indicate that the battery of the medical device apparatus 102 is fully charged. The indicator 134 being other colors, such as red, orange, yellow, amber, and / or flashing may indicate a battery malfunction or power level.

[0028]

[0037] The medical device apparatus 102 may include one or more buttons to control the system 100. For example, the medical device apparatus 102 may include buttons 126 and 128 to control the power status and functions of the medical device apparatus 102. In some embodiments, the button 126 is a power on / off button for controlling the power status of the medical device apparatus 102. For example, a user may press the button 126 to power on the medical device apparatus 102. The button 128 may be a manual breath button that delivers a single breath at a predefined tidal volume to the patient. In some embodiments, the button 128 presses the button 126 to deliver a single breath to the patient for a predefined amount of time before the medical device apparatus 102 delivers the single breath to the patient. It may need to be pushed.

[0029]

[0038] 1-4, the medical device apparatus 102 may include a pneumatic system or blower 104 that may include a motor 110 and a fan 112. The pneumatic system 104 may be an electromechanical pneumatic system. The motor 110 may be coupled to the fan 112, and the motor 110 may be configured to rotate the fan 112 to generate an airflow. In some embodiments, the motor 110 is configured to rotate the fan 112 at up to 37,500 revolutions per minute (RPM). The fan 112 may rotate to generate an airflow exiting the blower 104. The motor 110 may be coupled to a control system 106 that may control the motor 110. In some embodiments, the fan 112 is configured to provide up to 1,000 liters per minute (LPM). In some embodiments, the fan 112 is configured to rotate at greater than 37,500 RPM and greater than 1,000 LPM.

[0030]

[0039] In some embodiments, the blower 104 may be disposed within the housing 114. The housing 114 may be sized and shaped to receive the blower 104 and may be a single piece. For example, the housing 114 may be made of two halves and configured to receive the blower 104 such that the blower 104 is disposed within the housing 114. Having the housing 114 be made of two halves that enclose the blower 104 allows for a reduction in components and materials required for the manufacturing system 100. The blower 104 may include an inflow body that may be disposed within the housing 114. In some embodiments, the inflow body of the blower 104 may be the only portion of the blower 104 that is disposed within the housing 114.

[0031]

[0040] With reference to FIG. 1, the medical device apparatus 102 may include a control system 106. The control system 106 may be a microcontroller, a peripheral interface controller (PIC), a system on a chip (SoC), or a processor. In some embodiments, the control system 106 is a low-power controller. For example, the control system 106 may be a low-power controller coupled to a power source such that the control system 106 is configured to run for an extended period of time (e.g., years). The control system 106 may be coupled to one or more components of the system 100. In some embodiments, the control system 106 is coupled to the blower 104 to control a motor 110 that controls a fan 112. In some embodiments, the control system 106 controls the volume of gas delivered to the patient by reducing the speed of the fan 112. For example, the control system 106 may reduce the power delivered to the motor 110, thereby reducing the speed of the fan 112 to reach a target amount of gas delivered to the patient through the breathing circuit 200. The control system 106 may include a writing device 113, such as a radio frequency identification (RFID) chip / tag, that may be configured to write information to a transmitting device 117. In some embodiments, the control system 106 is coupled to a power source 108. However, the control system 106 may be coupled to its own power source.

[0033]

[0042] In some embodiments, the transmitting device 117 is stored within the medical device apparatus 102 and communicatively coupled to the control system 106. However, the transmitting device 117 may be disposed on or near the housing 132 of the medical device apparatus 102 and configured to communicate wirelessly with the control system 106. For example, the transmitting device 117 may be coupled to an exterior surface of the housing 132 and may wirelessly receive information from the control system 106. The transmitting device 117 may be a storage device configured to wirelessly transmit information, such as a wireless transmitting device. For example, the transmitting device 117 may include one or more of an RFID chip / tag, a near field communication chip, a Bluetooth transmitter, a digital barcode, or a WiFi module. In some embodiments, the transmitting device 117 transmits information only upon request. However, the transmitting device 117 may be configured to transmit information automatically and / or autonomously without intervention by a user or an external device. The transmitting device 117 may be configured for low power consumption. In some embodiments, the transmitting device 117 is configured to receive power only from an external power source. However, the transmitting device 117 may be powered by the power supply 108 or by its own power source.

[0034]

[0043] The control system 106 may, for example, receive information associated with the status of the system 100 and store the information in the memory 115 or directly in the transmitting device 117. The writing device 113 may access the memory 115 and write the information stored in the memory 115 to the transmitting device 117. In some embodiments, the memory 115 includes the transmitting device 117. The memory 115 may include, for example, random access memory (RAM), a hard disk drive, and / or a removable storage drive, such as a floppy disk drive, a magnetic tape drive, an optical disk drive, or a wireless device such as an RFID tag.

In some embodiments, the tube 202 is a cylindrical lumen configured to allow air flow from the medical device apparatus 102 to the patient interface 300. The tube 202 may be configured to include an exhaust valve 208, a flow sensor 210, and a patient filter 212. The exhaust valve 208 may be disposed on or within the tube 202 and configured to open upon exhalation of a patient using the system 100 to allow air to flow out of the patient. The exhaust valve 208 may be closed during inspiration to prevent air from exiting the system 100, thereby increasing efficiency. For example, the exhaust valve 208 may be closed during inspiration to ensure that an adequate amount and flow of air reaches the patient interface 300.

[0039]

[0048] In some embodiments, the exhaust valve 208 is controlled by the control system 106 to control the patient's exhalation. In another embodiment, the exhaust valve 208 is controlled based on the patient's exhalation. In yet another embodiment, the exhaust valve is controlled by both the control system 106 and the patient's exhalation. The exhaust valve 208 may be configured to allow for a particular breathing rate, but may also be opened by the patient's exhalation. For example, for a breathing rate of 12 (one breath every 5 seconds), the exhaust valve 208 may open every 5 seconds, or may open more than every 5 seconds if the patient is breathing at a different rate.

[0040]

[0049] In some embodiments, the breathing circuit 200 includes a flow sensor 210, which may be disposed on or in the tubing 202. The flow sensor 210 may be configured to sense the flow of air within the breathing circuit 200. For example, the flow sensor 210 may detect the rate and amount of air flowing through the tubing 202. In some embodiments, the flow sensor 210 is coupled to the control system 106 to provide feedback to the system 100. For example, the flow sensor 210 may provide information to the control system 106, which may alter parameters of the blower 104 based on the information.

[0041]

[0050] The breathing circuit 200 may further include a patient filter 212 that may be disposed proximal to the second end 206 of the tube 202.

The patient filter 212 may be configured to filter out particles in the air. For example, the patient filter 212 may filter out particles and airborne viruses to protect a patient using the system 100.

[0042]

[0051] 1, the system 100 may include a patient interface 300. The patient interface 300 may be a device that is secured to the patient's face. For example, the patient interface 300 may be a bag valve mask, a respirator, or an endotracheal (ET) tube used for intubation.

[0043]

[0052] 4, the medical device apparatus 102 may further include various inputs for coupling the medical device apparatus 102 to other components of the system 100. In addition to the inlet 118 and the outlet 116, the medical device apparatus 102 may include a control line port 136, a pressure line port 138, a differential pressure tubing port 140, a flow sensor port 142, a data communication port 144, and a power port 146. The control line port 136 may be used to couple an exhaust valve 208 and the medical device apparatus 102. For example, the exhaust valve 208 may be coupled to the medical device apparatus 102 at the control line port 136 such that the medical device apparatus 102 can control the opening and closing of the exhaust valve 208. The pressure line port 138 and the differential pressure tubing port 140 may be used to couple one or more pressure sensors to the medical device apparatus 102. The flow sensor port 142 may be used to couple a flow sensor 210 to the medical device apparatus 102. For example, the flow sensor 210 may be coupled to the medical device apparatus 102 at the flow sensor port 142 such that the medical device apparatus 102 can receive information from the flow sensor 210. The data communication port 144 may be used to couple the medical device apparatus 102 to an electronic device, such as a computer system, a mobile device, a server, etc. The power port 146 may be used to couple the medical device apparatus 102 to a power source. For example, the power port 146 may be configured to couple the power source 108 to the power source to provide power to the medical device apparatus 102 through the power source 108.

[0044]

[0053] The medical device apparatus 102 may include a port plate 119.

For example, the inlet 118 may include a specialized cover configured to allow only a reservoir of a specific gas or fluid to flow into the inlet 118. In some embodiments, the cover 121 may prevent inadvertent connection of the breathing circuit 200 to an incorrect connector. In some embodiments, a user must actively remove the cover 121 from the inlet 118 to allow connection of an air / gas source to the inlet 118. In some embodiments, the cover 121 may be configured to allow connection of an air / gas source to the inlet 118. 1 may be coupled to the port plate 119. For example, the cover 121 may be hingedly coupled to the port plate 119 to allow for covering of the inlet 118. In some embodiments, the cover 121 may allow ambient air to flow into the inlet 118 without removing the cover 121 from the inlet 118. In some embodiments, the cover 121 may have special markings to indicate which air / gas source may be coupled to the inlet 118. In some embodiments, a special tool is required to remove the cover 121 from the inlet 118 to prevent inadvertent connection to the inlet 118. In some embodiments, the cover 121 includes a sensor only to allow removal from the inlet 118 when a particular gas is detected. The cover 121 may also be configured to prevent debris from entering the inlet 118.

[0046]

[0055] In some embodiments, the port plate 119 may include a test cap configured to enable testing of the airflow and blower 104 of the medical device apparatus 102. The test cap may be configured to be disposed over the port plate 119 and may enable air coming in from the outlet 116 of the fan 112 to pass through the test cap and into a pressure sensor disposed on the port plate 119 or the test cap. For example, the test cap may include a recess that allows air to flow from the outlet 116 to a pressure sensor to determine the pressure of the air provided by the blower 104. The recess in the test cap may allow air to be directed from the outlet 116 to a pressure sensor that may be disposed on the port plate 119. For example, the test cap may enable testing of the blower 104 when the medical device apparatus 102 is in storage. The test cap may be configured to ensure the integrity of the pressure sensor of the medical device apparatus 102 in addition to providing additional protection to the port plate 119 and the outlet 116. In some embodiments, a recess in the test cap may allow air to flow from the outlet 116 onto the port plate 119 and / or to other sensors disposed within the test cap. The test cap may be hingedly coupled to the port plate 119 or the housing 132 and may be configured to be completely removable from the medical device apparatus 102.

[0047]

[0056] 5, both ambient air and oxygen may enter the gas reservoir 150 and mix together. Gas from the gas reservoir 150 may enter the medical device apparatus 102 through the inlet 118 to prevent outside debris from entering the medical device apparatus 102. The gas is then directed through an air passage contained within the medical device apparatus 102 and through the outlet 116 into the breathing circuit 200.

[0048]

[0057] In some embodiments, the system 100 may be configured to manage status checks or self-diagnostics to ensure that all components are operating correctly and that there are no malfunctions. In some embodiments, the control system 106, in addition to reporting the operational status of the system 100, is configured to test various components of the system 100 to determine the functional status of, for example, the blower 104, the power supply 108, the writing device 113, the memory 115, the transmitting device 117, and the control system 106. For example, the control system 106 may be configured to receive information from the memory 115 regarding any broken cores, from the blower 104 regarding blockages in the fan 112, from the outlets 116 or 118 regarding blockages, from the power supply 108 regarding improper voltage, or any other information necessary to ensure that the medical device apparatus 102 is functioning properly. In some embodiments, the control system 106 automatically receives information from various components of the system 100 on a periodic or aperiodic basis. For example, the control system 106 may receive information about some or all of the components of the medical device apparatus 102 without receiving a request from a user or other device.

[0049]

[0058] In some embodiments, the medical device apparatus 102 of the system 100 is configured to manage a status check, store the result of the status check, and then power off. In some embodiments, the medical device apparatus 102 is configured to perform a self-diagnosis when the medical device apparatus 102 is in storage or not in active use (e.g., in a powered off state). The result of the status check may be stored in the memory 115, which may be configured to transmit the result without receiving power from the medical device apparatus 102. For example, the medical device apparatus 102 may power on, manage a status check, store the result of the status check in the transmitting device 117 and / or in the memory 115, and then power off. The transmitting device 117 may be configured to transmit the result only when interrogated by an external power source. The external power source may be a receiving or reading device that provides power to the transmitting device 117, enabling the transmitting device 117 to transmit the result. This allows the medical device apparatus 102 to conserve power since it does not need to be powered on to transmit the results of the status check, and allows the medical device apparatus 102 to provide the results at any time upon interrogation by a user. However, the transmitting device 117 may be configured to automatically transmit the results periodically or aperiodically. For example, the transmitting device 117 may automatically transmit the results without user intervention.

[0050]

[0059] The control system 106 may receive status data regarding the functional status of the system 100 and store the status data by the memory 115. The status data may be any information describing the functionality and operation of any component of the system 100. The writing device 113 may access the status data stored in the memory 115 and write the status data to the transmitting device 117 stored in the medical device apparatus 102. A user may wirelessly access the status data from the transmitting device 117 without the need to power on the medical device apparatus 102. This allows the medical device apparatus 102 to transmit the status data wirelessly and without powering on, thereby reducing power consumption. For example, a user may interrogate the transmitting device 117 and receive the status data while the medical device apparatus 102 is powered off. A user may interrogate the transmitting device 117 using a receiving or reading device. In some embodiments, the receiving or reading device may be configured to provide power to the transmitting device 117, allowing the transmitting device 117 to transmit status data without the need to power on the medical device apparatus 102. In some embodiments, the medical device apparatus 102 does not provide power to the transmitting device 117. In some embodiments, the transmitting device 117 may transmit status data without the need for a user to physically contact the medical device apparatus 102. For example, the transmitting device 117 may transmit status data only upon request from an external power source, such as a reading or receiving device. However, the transmitting device 117 may be configured to autonomously and automatically transmit status data periodically or aperiodically. In some embodiments, the status data may include one or more of a serial number, a software version, accessory information, power source information, date of last status data request, date of last operation, date of manufacture, date of last repair, replaced components, results of previous status checks, a usage report, accessory information, battery information, and battery status.

[0051]

[0060] The control system 106 may automatically test the medical device apparatus 102 periodically, on a scheduled basis, or aperiodically. For example, the control system 106 may power on the medical device apparatus 102 and test all components of the medical device apparatus 102 periodically, such as every month, every three months, or every six months. In some embodiments, a user may schedule a specific date for the control system 106 to power on the medical device apparatus 102 and test all components of the medical device apparatus 102. In another embodiment, the control system 106 may aperiodically power on the medical device apparatus 102 and test all components of the medical device apparatus 102. For example, tests may need to be performed more frequently the longer the medical device apparatus 102 has been in storage. In some embodiments, the control system 106 tests the medical device apparatus 102 without user intervention.

[0052]

[0061] In some embodiments, the control system 106 is configured to autonomously power on the medical device device 102 to perform a self-diagnosis or status check. For example, the control system 106 may be configured to periodically or non-periodically wake up the medical device device to perform a self-diagnosis or status check. In some embodiments, the control system 106 performs the self-diagnosis or status check in a "silent mode" such that the user is not aware that a self-diagnosis or status check is being performed. For example, the control system 106 may perform the self-diagnosis or status check without turning on the user interface 124 or the indicators 133, 134 and without user intervention. In some embodiments, the user requests the control system 106 to perform a self-diagnosis or status check by interacting with the user interface 124 or engaging / actuating the button 126. For example, the user may actuate the button 126 for approximately five seconds to initiate a self-diagnosis or status check on the medical device device 102. However, a user may actuate button 126 for 3, 4, 6, or more than 6 seconds to initiate a self-diagnostic or status check.

[0053]

[0062] In some embodiments, the control system 106 causes activation of the indicators 133, 134, the user interface 124, or the speaker 141 to indicate that the medical device apparatus 102 is performing a self-diagnosis or status check. For example, the user interface 124 may light up with a message indicating that a self-diagnosis or status check is being performed, or the speaker 141 may produce an audio output to indicate to a user that a self-diagnosis or status check is being performed.

[0054]

[0063] In some embodiments, the medical device apparatus 102 is configured to provide instructions regarding correcting an error. For example, the control system 106 may request a self-diagnosis or status check for one or more components and may receive an error. In response to the received error, the control system 106 may cause the user interface 124 and / or the speaker 141 to provide instructions to the user. For example, if the control system 106 receives an error from one or more components, such as the blower 104, the user interface 124 may display graphics and / or animations instructing the user how to correct the error associated with the blower 104. In some embodiments, the medical device apparatus 102 provides step-by-step instructions to the user via the user interface 124 or microphone, such that the user progresses through the instructions at their own pace. For example, the user may interact with the user interface 124 to progress through the step-by-step instructions, or may use their voice to instruct the medical device apparatus 102 to skip the next instruction or to repeat the instructions for a particular step.

[0055]

[0064] In some embodiments, the control system 106 detects errors while the medical device device 102 is in use. For example, an error may occur that results in the medical device device 102 not functioning properly while in use with a patient. The control system 106 detects errors while the medical device device 102 is in use. The control system 106 may detect errors and provide real-time instructions to the user to correct the errors to enable the medical device apparatus 102 to return to a properly functioning state. In some embodiments, the control system 106 causes the speaker 141 to provide audio instructions to the user to correct the errors. The speaker 141 may be configured to correspond to graphics and / or animations presented by the user interface 124. In some embodiments, the user interface 124 is configured to receive input from the user to step through or repeat instructions associated with correcting the errors.

[0056]

[0065] In some embodiments, the control system 106 is configured to transmit text, audio, images, graphics, and / or video regarding correcting the error to an electronic device associated with the user. The control system 106 may be configured to provide instructions for correcting the error while the medical device device 102 is powered on. In practice, the control system 106, which may be coupled to a power source separate from the power source 108, may receive errors from one or more components while the medical device device 102 is powered off. When the medical device device 102 is powered on, the control system 106 may cause the user interface 124 and / or the speaker 141 to provide instructions to the user to correct the error. However, the control system 106 may provide instructions to the user while the medical device device 102 is in use. In some embodiments, the control system 106 receives errors while the medical device device 102 is in use and provides instructions in real time. The control system 106 may receive errors without performing a status check or self-diagnosis. For example, during use of the medical device apparatus 102, an error may occur within the breathing circuit 200 or the patient interface 300. The control system 106 may detect that an error has occurred and may provide instructions to the user via the user interface 124 and / or speaker 141 on how to resolve or correct the error in real time.

[0057]

[0066] In some embodiments, the control system 106 is configured to provide instructions to the user regarding the appropriate therapy or optimal treatment for the patient. For example, the user interface 124 may provide audio, video, graphical, and / or textual recommendations to the user on services and treatments to be provided to the patient. During use, various parameters of the medical device apparatus 102 (e.g., PIP, TV, RR, PEEP, I:E ratio, ventilation mode, flow rate) may need to be adjusted by the user when the medical device apparatus 102 is being used to treat a patient. The control system 106 may instruct the user interface 124 to provide instructions to the user for adjusting these parameters. In some embodiments, the control system 106 provides instructions to the user via the user interface 124 based on the current treatment that the medical device apparatus 102 is providing to the patient. For example, the medical device apparatus 102 may be a ventilator that provides oxygen to a patient at a particular tidal volume, and the user interface 124 may provide instructions to a user to vary the tidal volume based on information that the control system 106 receives from various sensors or components of the medical device apparatus 102.

[0058]

[0067] In practice, multiple medical device devices 102 may be stockpiled or placed in storage for an extended period of time before use, and thus may require multiple tests to ensure that the medical device devices 102 are functioning properly before use. In practice, previous medical devices require physical intervention (e.g., opening the device, turning the device on, etc.) to determine if the device is functioning properly. This is an inefficient use of resources and also drains the device power supply. In some embodiments, the medical device devices 102 automatically power on and perform tests of various components stored within the medical device devices 102 to generate status data. The control system 106 of the medical device devices 102 may store the status data in the memory 115. The writing device 113 may access the status data from the memory 115. In some embodiments, the control system 106 transmits the status data directly to the writing device 113. The writing device 113 may write the status data to a sending device 117, such as an RFID tag, which stores the status data. After the writing device 113 writes the status data to the sending device 117, the medical device apparatus 102 may shut down to conserve power. A user may obtain the status data by using a receiving or reading device, such as an RFID reader, to wirelessly receive the status data while the medical device apparatus 102 is powered off.

[0059]

[0068] In some embodiments, the medical device apparatus 102 may transmit status data only when requested by a user. For example, the control system 106 may receive the status data and the writing device 113 may receive the status data from the control system 106 and / or the memory 115. The writing device 113 may write the status data to the transmitting device 117, which may store the status data. The transmitting device 117 may transmit the status data only when requested by a user, such as by the user placing a receiving device adjacent to the medical device apparatus 102 or by the user interacting with the medical device apparatus 102 via the user interface 124 or buttons 126, 128. However, the transmitting device 117 may be configured to transmit the status data autonomously without user intervention. For example, the transmitting device 117 may detect that a receiving device is located proximate to the medical device apparatus 102 and may automatically and autonomously transmit the status data. In some embodiments, the transmitting device 117 is configured to autonomously and automatically transmit the status data periodically or aperiodically to a receiving device located proximate or remotely to the medical device apparatus 102.

[0060]

[0069] In some embodiments, the control system 106 receives information from accessories associated with the medical device apparatus 102. For example, each accessory may include one or more wireless transmitting devices configured to transmit information to the control system 106 when interrogated, the wireless transmitting devices disposed in or on the accessory. The medical device apparatus 102 may include one or more accessories, each of which may store information in a respective wireless transmitting device. The wireless transmitting device associated with each of the accessories may store information about the accessory, such as product type, expiration date, model number, serial number, modification, last test, last use, etc. In some embodiments, the control system 106 may interrogate the wireless transmitting device to receive accessory information about the accessory and store the accessory information in the memory 115. The control system 106 may be configured to interrogate all accessories proximate to the medical device apparatus 102. For example, the control system 106 may interrogate all accessories within a predefined radius to ensure that the medical device apparatus 102 has all accessories it needs to function. The writing device 113 of the medical device apparatus 102 may write accessory information about the accessory to the transmitting device 117, which may store the accessory information along with the status data. In some embodiments, the control system 106 is configured to interrogate any accessories or devices within a predefined proximity and / or radius and write any information received to the transmitting device 117 and / or memory 115.

[0061]

[0070] In some embodiments, the medical device apparatus 102 is configured to create a mesh network with surrounding medical device apparatuses, allowing the transmission and reception of status data associated with multiple medical device apparatuses. may be configured to interrogate one or more medical device devices within a proximity range or within a predefined radius. Each medical device device may be configured to interrogate neighboring medical device devices and store information regarding the status data of the medical device devices in proximity such that each medical device device includes the status data of all medical device devices in the surrounding area. For example, the medical device device 102 may interrogate and write to the transmitting device 117 and / or memory 115 the status data associated with all medical device devices in the surrounding area. This allows a user to only need to interrogate a single medical device device to obtain information from all medical device devices in the surrounding area. The surrounding area may be a radius of at least 1 foot, at least 2 feet, at least 3 feet, at least 4 feet, at least 5 feet, at least 10 feet, or at least 25 feet. In some embodiments, the medical device apparatus 102 may interrogate surrounding medical device apparatuses to determine the status of accessories associated with the surrounding medical device apparatuses. This allows a user to determine which medical device apparatuses and / or accessories require attention by interrogating only the medical device apparatus 102.

[0062]

[0071] In some embodiments, the mesh network created by the medical device apparatus 102 and the surrounding medical device apparatuses allows the control system 106 to map the locations of the surrounding medical device apparatuses along with status data associated with each medical device apparatus. This allows a user to interrogate the medical device apparatus 102 and obtain status data for all surrounding medical device apparatuses in addition to determining the locations of the surrounding medical device apparatuses. Determining the locations of the surrounding medical device apparatuses allows a user to easily determine which medical device apparatuses are not functioning properly based on the status data, and also allows a user to easily find and replace malfunctioning medical device apparatuses. In some embodiments, the medical device apparatus 102 is configured to transmit a map of the locations of the surrounding medical device apparatuses to the user when requested.

[0063]

[0072] In some embodiments, the medical device apparatus 102 may include a wireless network module, such as a WiFi chip / card, configured to communicate with the control system 106 and one or more external devices. The one or more external devices may include a writing device 113, a transmitting device 117, a server, a computer, a mobile device, or an external transmitter. The wireless network module may receive a signal from the external device that causes the medical device apparatus 102 to power on and manage a status check. Status data resulting from the status check may be stored in the memory 115 and / or wirelessly transmitted to the writing device 113, which may be disposed outside the medical device apparatus 102. The writing device 113 may then write the status data to the transmitting device 117, which may be stored in, on, or outside the housing 132 of the medical device apparatus 102. In some embodiments, the writing device 113 and the transmitting device 117 are each disposed proximate to the medical device apparatus 102. In an alternative embodiment, the writing device 113 and the transmitting device 117 are each disposed remotely to the medical device apparatus 102 .

[0064]

[0073] In some embodiments, the medical device device 102 may provide status data in additional ways. In some embodiments, an indicator 133 on the medical device device 102 may provide the status of the medical device device 102. For example, The indicator 133 may be an LED indicator or status light that may display a green light when no malfunction is present or a red light when a malfunction is present. When a red light is displayed indicating a malfunction of the medical device apparatus 102, the user may obtain status data from the transmitting device 117 to receive detailed results of the test to resolve the malfunction. In some embodiments, the receiving device and / or writing device 113 are disposed adjacent to the medical device apparatus 102 to consistently receive status data from or write data to the transmitting device 117 whenever the medical device apparatus 102 performs tests of various components stored in the medical device apparatus 102. For example, whenever a test of the medical device apparatus 102 is performed, the control system 106 and / or memory 115 may provide the status data to the transmitting device 117. The transmitting device 117 may transmit the status data to the receiving device upon receiving the status data. The receiving device may alert the user when any malfunction contained in the status data is present or transmit the status data to a central server or database for the user to access. This allows for monitoring of multiple medical device devices 102 in storage without having a user periodically check the status of each medical device device 102 in storage. Additionally, this allows for real-time delivery of status data from the medical device devices 102.

[0065]

[0074] In some embodiments, the medical device apparatus 102 may include a speaker 141, additional lights, and / or additional display screen. The medical device apparatus 102 may be configured to alert the user via one or more of the user interface 124, the indicators 133, 134, the user interface 124, the display screen, or other modes of alerting the user.
