Description

[Technical field]

[0001] The present disclosure relates generally to mechanical ventilators, and more particularly to a modular mechanical ventilator system adapted to provide continuous or intermittent ventilatory support for the care of individuals requiring mechanical ventilation. [Background technology]

[0002] A wide range of conditions may require some form of ventilation. These conditions may include hypoxemia, various forms of respiratory failure, and airway compromise. There are also non-respiratory and non-airway conditions that require ventilation, such as congestive heart failure and neuromuscular diseases.

[0003] Various types of ventilatory systems have been developed in the prior art to improve the quality of life for many patients who require long-term ventilation therapy. Some of these prior art systems are compact, lightweight, and portable, while others are rugged but not portable, or can be worn by the patient. However, the known prior art suffers from shortcomings in that they provide ventilatory systems that are uniquely adapted for use in any of a number of different configurations and provide any of a number of different types of ventilatory support corresponding to those configurations. These shortcomings are addressed by the modular ventilatory system of the present disclosure, as described in more detail below. Summary of the Invention [Problem to be solved by the invention]

[0004] To solve these and other problems, new modular ventilator systems that are convertible between stationary, extended range, and standalone configurations and methods of using these ventilator systems for continuous or intermittent ventilatory support for the care of individuals requiring mechanical ventilation have been devised. More specifically, the modular ventilator system is primarily comprised of a ventilator, a compressor unit, and a patient interface, and can be used in at least three different configurations, including stationary, extended range, and standalone. In the stationary configuration, the ventilator is docked with the compressor unit, and the patient interface is connected to the compressor unit for ventilation of a stationary patient. In the extended range configuration, which may allow the patient to engage in local activities of daily living, the ventilator is not docked with the compressor unit, but instead is located near the patient where it receives compressed air from the compressor via a compressed gas supply hose, and the patient interface is connected to the ventilator. In a stand-alone configuration that may allow the patient to engage in non-local activities, the ventilator is not docked or otherwise connected to the compressor unit, but instead is connected to and receives compressed gas from an external source of compressed gas, such as an oxygen or air bottle, or a compressed gas source in the wall of the hospital, and a patient interface is connected to the ventilator. [Means for solving the problem]

[0005] In accordance with one contemplated embodiment of the modular ventilation support device disclosed herein, the modular ventilation support device may include a compressor unit, a ventilator, and a patient interface. The compressor unit may include a compressor, a ventilator dock having a ventilator dock compressed gas exhaust port and a ventilator dock ventilation gas intake port, and a compressed gas exhaust port of the compressor unit. The ventilator is configured to removably dock with the ventilator dock and includes a ventilator ventilation gas exhaust port and a ventilator compressed gas intake port. The patient interface is for receiving ventilation gas and delivering ventilation gas to a patient, and has a patient interface gas intake port that is movable between an arrangement in fluid communication with the ventilation gas exhaust port of the compressor unit and an arrangement in fluid communication with the ventilation gas exhaust port of the ventilator. When transitioning to the stationary configuration, the ventilator is docked in the ventilator dock, the compressed gas intake port of the ventilator is in fluid communication with the compressed gas exhaust port of the ventilator dock, the ventilation gas exhaust port of the ventilator is in fluid communication with the ventilation gas intake port of the ventilator dock, and the patient interface gas intake port is in fluid communication with the ventilation gas exhaust port of the compressor unit, such that compressed gas is provided to the ventilator by the compressor unit and ventilation gas is returned to the compressor unit and then output from the compressor unit to the patient interface. When transitioning to the extended range configuration, the ventilator is not docked in the ventilator dock, the compressed gas intake port of the ventilator is in fluid communication with the compressed gas exhaust port of the compressor unit, and the patient interface gas intake port is in fluid communication with the ventilation gas exhaust port of the ventilator, such that compressed gas is provided to the ventilator by the compressor unit and ventilation gas is provided to the patient interface by the ventilator without being returned to the compressor unit. When transitioning to the standalone configuration, the ventilator is not secured in the ventilation dock, the ventilator compressed gas intake port is in fluid communication with an external compressed gas source, and the patient interface gas intake port is in fluid communication with the ventilator ventilation gas exhaust port, so that compressed gas is provided to the ventilator by the external compressed gas source, and the compressed gas is provided to the ventilator without passing through the compressor unit.

[0006] Additionally, methods of using these embodiments of the modular ventilatory support device disclosed herein have been devised, for transitioning the modular ventilatory support device from one of the stationary, extended range and standalone configurations to another, comprising a first step of providing a modular ventilatory support device having the aforementioned components of a compressor unit, a ventilator and a patient interface, and a second step of transitioning the modular ventilatory support device from one of the stationary, extended range and standalone configurations to another, the modular ventilatory support device transitioning to a stationary configuration when the ventilator is docked with a ventilator dock, the compressed gas intake port of the ventilator is in fluid communication with the compressed gas exhaust port of the ventilator dock, the ventilation gas exhaust port of the ventilator is in fluid communication with the ventilation gas intake port of the ventilator dock, and the patient interface gas intake port is in fluid communication with the ventilation gas exhaust port of the compressor unit. As a result, compressed gas is provided to the ventilator by the compressor unit, and ventilation gas is returned to the compressor unit and then output from the compressor unit to the patient interface. When transitioning to the extended range configuration, the modular ventilation support device is not docked with the ventilator dock, the compressed gas intake port of the ventilator is in fluid communication with the compressed gas exhaust port of the compressor unit, and the patient interface gas intake port is in fluid communication with the ventilation gas exhaust port of the ventilator. As a result, compressed gas is provided to the ventilator by the compressor unit, and ventilation gas is provided to the patient interface by the ventilator without being returned to the compressor unit. When transitioning to the standalone configuration, the modular ventilation support device is not secured with the ventilation dock, the compressed gas intake port of the ventilator is in fluid communication with the external compressed gas source, and the patient interface gas intake port is in fluid communication with the ventilation gas exhaust port of the ventilator. As a result, compressed gas is provided to the ventilator by the external compressed gas source, and compressed gas is provided to the patient interface by the ventilator without passing through the compressor unit.

[0007] It is further contemplated that the above and other contemplated embodiments and methods may include certain other aspects. For example, the compressor unit may further comprise a low flow gas inlet port, which may be a low flow oxygen inlet port. The compressor may also additionally or alternatively be configured to compress ambient air, and the compressor unit may further comprise one or more ambient air ports for introducing ambient air into the compressor. The one or more ambient air ports may further comprise a filter. The compressed gas exhaust port of the compressor unit may comprise a Diameter Index Safety System (DISS) coupling. It is further contemplated that the ventilator may be powered and may comprise a rechargeable battery. As such, the ventilator dock may be configured to provide power to the ventilator for powering the ventilator and for recharging the rechargeable battery when the ventilator is docked at the ventilator dock. The ventilator may further comprise a user interface and a wireless transmitter, and the compressor unit may further comprise a wireless receiver. As a result, it can be seen that the compressor may be controllable by signal transmission from the wireless transmitter to the wireless receiver, initiated by user input at the user interface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Common reference numbers are used throughout the drawings and detailed description to refer to like elements. According to various aspects of the present disclosure, a modular ventilatory support system is devised that can transition between a stationary configuration, an extended range configuration, and a standalone configuration, and a method for implementing such transitions. The modular components of the modular ventilatory support system are devised to include at least a compressor unit, a ventilator that can dock with the compressor unit, and a patient interface that can be connected to either the compressor unit or the ventilator section. Due to their modularity, these components can be rearranged into at least three different configurations, which have different attributes related to mobility and expected duration of use. Thus, by using the modular ventilatory support system and methods discussed herein, a user can select the optimal configuration for the modular ventilatory support system to fit their current needs at any given time, and then transition the modular ventilatory support system to that configuration to achieve flexibility benefits without using multiple different ventilatory support systems. For example, transitioning to a stationary configuration limits mobility but maximizes duration of use. Transitioning to an extended range configuration increases mobility but duration of use is limited by the battery power of the ventilator. Moving to a standalone configuration maximizes mobility but limits duration of use by ventilator battery power and external gas supply, so it can be seen that the modular ventilation system of the present disclosure can greatly improve the quality of life of patients.

[0011] 1, there is shown a front perspective view of a ventilatory support device 10 according to one embodiment of the disclosed modular ventilation system. The ventilatory support device 10 may be, for example, in an exemplary embodiment, a Breathe Technologies Life2000 (trademark) ventilator, as described in Appendix A herein. ) may be one or more components of a ventilation system, the disclosure of which is incorporated herein by reference. However, it may be understood that the ventilation support device 10 may be any ventilation system having the components described herein and / or operating according to the methods disclosed herein. In an exemplary embodiment, the ventilation support device 10 is transitionable between a stationary configuration, an extended range configuration, and a standalone configuration. The ventilation support device 10 includes at least a ventilator 12, a compressor unit 14, and a patient interface 80. In the configuration shown in FIG. 1, i.e., the stationary configuration, the ventilator 12, the compressor unit 14, and the patient interface 80 are used together. However, as described below, in other contemplated configurations to which the ventilation system may transition, the ventilator 12 and the ventilation support device 10 of the patient interface 80 may be used independently of the compressor unit 14.

[0012] The ventilator 12 is operative to provide ventilation gas and, in an exemplary embodiment, may be a Breathe Technologies Life2000 ventilator, described in Appendix A. The unit is intended for use with the Breathe Technologies Life2000 Compressor, also described in Appendix A. In some embodiments, the ventilation gas may be used in conjunction with an external compressed gas source, which may be a 50 PSI pressure source. The ventilation gas may be any gas that the patient is able to breathe using the ventilation support device 10, such as, for example, oxygen or air.

[0013] Ventilator 12 may operate according to known methods for receiving compressed gas, generating ventilation gas, and providing ventilation gas to a patient in need of medical ventilation. However, in exemplary embodiments, it is contemplated that ventilator 12 may be configured and / or operate according to certain known configurations of ventilators and / or methods of controlling and delivering ventilation gas to provide therapeutic respiratory support, such as those described in Applicant's U.S. Pat.

[0014] Compressor unit 14, in an exemplary embodiment, may be a Breathe Technologies Life2000 compressor, as described in the attached Appendix A. This compressor includes a continuous source of compressed gas. The ventilator 12 is an electro-pneumatic power unit that provides a ventilator 12 with a power supply that can be electrically connected to the compressor unit 14 and can also be a charging station for the ventilator 12. It is contemplated that the ventilator 12 and compressor unit 14 may be configured such that the ventilator 12 may be docked with the compressor unit 14, for example, by inserting the ventilator 12 into the compressor unit 14, as shown in FIG. 1. However, it will be understood that the ventilator 12 may be docked with the compressor unit 14 in other ways than by insertion, and the exact docking method is not important so long as the docking establishes the necessary fluid connections between the ventilator 12 and the compressor unit 14. Such fluid connections are described in more detail below. However, those skilled in the art will recognize that assuming a docking scheme is used that involves inserting the ventilator 12 into the compressor unit 14, the shape or form factor of the receptacle or other opening in the compressor unit 14 that receives the ventilator 12 will be complementary to the shape or form factor of the ventilator 12 itself, as shown in FIG. 1, thereby providing both a functional and visual effect of a smooth and somewhat seamless integration between the two structural features.

[0015] Referring now to FIG. 2, a front view of a ventilator 12 is shown in accordance with an exemplary embodiment. As shown in the example of FIG. 2, the ventilator 12 may include a user interface 18 including, for example, a display 16, a ventilator power button 20, a ventilator power indicator light 22, an alarm speaker 24, a backup alarm speaker 26, and a breathing indicator light 28. The user interface 18 may include prescription setting buttons such as a high activity button 18a, a medium activity button 18b, and a low activity button 18c, and may further include other buttons, dials, sliders, switches, and the like. The display 16 may be a touch screen, in which case the user interface 18 may further include the touch screen functionality of the display 16. It may thus be understood that the user interface 18 of the ventilator may be configured to receive user input.

[0016] Referring now to Figure 3, a side view of an exemplary embodiment of the ventilator 12 is shown. As shown in the embodiment depicted in Figure 3, the ventilator 12 may further include other features, such as a belt clip socket 30 for attachment to a belt clip or other attachment to aid in attachment of the ventilator 12 to a person or object when not docked with the compressor unit 14. The belt clip socket 30 may be provided on both sides of the ventilator 12 (only one side is shown in Figure 3). The ventilator may also include a rechargeable battery 29 and a wireless transmitter 31.

[0017] Referring now to FIG. 4, a top view of an exemplary embodiment of the ventilator 12 is shown. As shown in the example of FIG. 4, the ventilator 12 may further include a ventilator battery charger connection port 32, a ventilator alarm silence button 34, and an additional port 36. The ventilator alarm silence button 34 may be used to silence an alarm (e.g., as described on pages 39 and 49 of Appendix A). The additional port 36 may be used by the manufacturer to interface with the ventilator 12, such as to send or receive data such as firmware updates, default operating modes, or error logs. In an exemplary embodiment, the additional port 36 is a USB port. However, it may be understood that in other embodiments, the additional port may be any port known or developed in the art for interfacing between devices, or may be omitted entirely.

[0018] 5, a bottom view of an exemplary embodiment of the ventilator 12 is shown. As shown in the example of FIG. 5, the ventilator 12 may further include a ventilator ventilation gas exhaust port 38 and a ventilator compressed gas intake port 40. The ventilator ventilation gas exhaust port 38 may be connected to a ventilator compressed gas intake port 40, for example, via a "JET PUMP ADAPTOR FOR VENTILATION SYSTEM" in an exemplary embodiment. The patient interface may be configured to receive the multi-lumen patient interface gas intake port 81 of the patient interface 80 described in Applicant's co-pending U.S. Patent Application Serial No. 14 / 020,032 (corresponding to U.S. Patent Application Publication No. 2015 / 0068519), the contents of which are incorporated herein by reference. Additionally, the patient interface may be an interface described in Applicant's U.S. Patent Nos. 8,839,791, 8,844,533, 9,038,634, 9,038,635, 9,132,250, 9,180,270, 9,227,034, and 9,327,092, the contents of which are incorporated herein by reference. However, in other embodiments, the ventilation gas exhaust port 38 of the ventilator may be configured to receive or otherwise fluidly connect to a patient interface gas intake port 81 of a patient interface 80 for delivering respiratory gas to the patient, where the patient interface 80 may be understood to include, but is not limited to, a nasal interface, nasal mask, respiratory mask, or nasal mask, or an intubation device.

[0019] 6, a front perspective view of the compressor unit 14 of an exemplary embodiment of the ventilation support device 10 is shown. As shown in the example of FIG. 6, the compressor unit 14 may include a ventilator dock 42, a compressor power indicator light 44, a compressor power button 46, a lock knob 48, a lock icon 50, an unlock icon 52, a battery charge status button 54, a battery charge indicator 56, a compressor unit compressed gas exhaust port 58, and a compressor unit ventilation gas exhaust port 60. The ventilator dock 42 may have a ventilator dock compressed gas exhaust port 43 and a ventilator dock ventilation gas intake port 45, and may be configured to provide power to the ventilator 12 for powering the ventilator 12 and for recharging the rechargeable battery 29 of the ventilator 12 when the ventilator 12 is docked to the ventilator dock 42. The ventilator dock compressed gas exhaust port 43 may be configured to interface with the ventilator compressed gas intake port 40 when the ventilator 12 is docked to the docking port 42 to form a generally sealed fluid connection between the two ports. Similarly, the ventilator dock ventilation gas intake port 45 may be configured to interface with the ventilator ventilation gas exhaust port 38 when the ventilator 12 is docked to the docking port 42 to form a generally sealed fluid connection between the two ports. Additionally, it may be appreciated that the docking port 42 may further comprise a power conduit for interfacing with the ventilator battery charger connection port 32 of the ventilator 12 to provide power to the ventilator 12 when docked to the docking port 42 for powering the ventilator 12 and for charging the rechargeable battery 29. This power conduit may be configured in certain embodiments to permit retraction and subsequent insertion or other form of connection into the ventilator battery charger connection port 32, such as when the locking knob 48 is actuated. It can be appreciated that this facilitates insertion of the ventilator 12 into the docking port 42.Those skilled in the art will recognize that the complementary, generally square (i.e., rectangular) configuration of ventilator 12 and corresponding docking port 42 in compressor unit 14 as shown in Figures 2-5 are exemplary only, and alternative complementary shapes may be substituted without departing from the spirit and scope of the present invention.

[0020] The lock icon 46 may also function as a ventilator charging indicator light. The compressed gas exhaust port 58 of the compressor unit may be a Diameter Index Safety System (DISS) coupling, for example a DISS1240 output connection port, in an exemplary embodiment, although it may be understood that in other embodiments the compressed gas exhaust port 58 may be any port suitable for delivering compressed gas.

[0021] 7, a rear perspective view of an exemplary embodiment of the compressor unit 14 is shown. In the exemplary embodiment, the compressor unit 14 further comprises a handle 62, a low flow gas (e.g., oxygen) inlet port 64, an internal battery 66, an outside air filter cover 68, one or more outside air vents 70, a water tray 72, a power connection port 74, an alarm speaker 76 (internal), a compressor-side alarm silence button 78, and a wireless receiver 79 (internal), in addition to a compressor 83 (internal) for providing compressed gas. The handle 62 may be positioned to ensure that the compressor unit 14 remains in an upright position when carried. The one or more outside air vents 70 may comprise an outside air filter 71 to prevent particulate matter from entering the compressor unit. The power connection port 74 may comprise a removable or displaceable cover. The compressor-side alarm silence button 78 may be used to silence an alarm (e.g., as described on page 24 of Appendix A). AC power is provided to the compressor unit 14 by connecting an external power source to the power connection port 74 using an AC power cord (e.g., as described on page 17 of Appendix A). The compressor 83 may be configured to compress ambient air and / or low pressure gas and to generate compressed gas for subsequent delivery to the ventilator 12. In an exemplary embodiment, one or more ambient air ports 70 allow ambient air to be introduced into the compressor 83 through an ambient air filter 71 and pressurized by the compressor 83 (e.g., as described on page 142 of Appendix A). It may also be appreciated that, for example, low pressure gas may be introduced into the compressor 83 via the low flow gas inlet port 64, and such low pressure gas may replace or supplement ambient air.

[0022] 8, there is shown a schematic diagram of the ventilation support apparatus 10 in a stationary configuration. When the ventilation support apparatus 10 is in a stationary configuration, the ventilator 12 is docked with the compressor unit 14, with the compressor unit 14 positioned preferably upright on a flat horizontal surface.

[0023] 9A-9D, there are shown front (FIGS. 9A and 9D) and enlarged cutaway front perspective (FIGS. 9B and 9C) views of the ventilation support apparatus 10 moving to a stationary configuration in an exemplary embodiment in a process having four steps. However, it can be appreciated that in other embodiments, the process of docking the ventilator 12 to the docking port 42 may differ. According to an exemplary embodiment of the docking process, the ventilator 12 is first ensured to be powered off (the ventilator 12 may be powered off using the ventilator power button 20) and then the locking knob 48 on the compressor unit 14 is ensured to be in the unlocked position shown in FIG. 9A, e.g., with the appropriate indicator marking on the locking knob 48 facing the unlocked icon 52. Next, as shown in Figure 9B, the ventilator 12 is positioned in the ventilator dock 42 of the compressor unit 14 with one end (e.g., bottom end) first inserted as shown, and pushed toward that end (e.g., in the direction of the arrow in Figure 9B) until it clicks into place, indicating that the compressed gas intake port 40 of the ventilator is interfaced to form a generally sealed fluid connection with the compressed gas exhaust port 43 of the ventilator dock, and the ventilation gas exhaust port 38 of the ventilator is interfaced to form a generally sealed fluid connection with the ventilation gas intake port 45 of the ventilator dock. Then, as shown in Figure 9C, the center of the ventilator 12 is pushed toward the compressor unit 14 (e.g., pushed at "push here" in Figure 9C) until the front of the ventilator 12 is flush with the front of the compressor unit 14 and the ventilator 12 clicks into place. Finally, as shown in FIGURE 9D, the lock knob 48 on the compressor unit 14 is turned to a locked position, e.g., a position where a suitable indicator mark on the lock knob 48 faces the lock icon 50. In this manner, the ventilator 12 may be docked with the compressor unit 14. As noted above, the lock icon 50 may function as a ventilator charging indicator light. Thus, when the compressor unit 14 is powered on and the ventilator 12 is properly docked, the lock icon 50 may be illuminated to indicate that the ventilator 12 is being charged by the compressor unit 14.

[0024] 10, there is shown a front perspective view of the ventilation support device 10 in a stationary configuration, including a patient interface 80. The patient interface 80 is for receiving and delivering ventilation gas to the patient and may be any dedicated or universal interface used to connect a non-invasive mask (e.g., full face mask, nasal mask, pillow mask) or tracheostomy tube to the ventilation support device 10 or ventilator 12. The patient interface 80 may be, for example, a Breath Technologies Universal Circuit™ interface in an exemplary embodiment. The patient interface 80 may be a compression The patient interface 80 has a patient interface gas intake port 81 that is movable between being in fluid communication with the compressed gas exhaust port 58 of the compressor unit of the compressor unit 14 and being in fluid communication with the ventilator ventilation gas exhaust port 38 of the ventilator 12. As shown in Figure 10, when the ventilation support apparatus 10 is in a stationary configuration, a patient interface 80 may be plugged into the compressed gas exhaust port 58 of the compressor unit.

[0025] 11, there is shown an enlarged cutaway rear perspective view of the low-flow gas tube 82 and the ventilation support device 10 in a stationary configuration. When using a prescription setting that uses oxygen as the source gas, a low-flow supplemental oxygen source (not shown), such as a stationary oxygen concentrator, may be connected to the compressor unit 14. As shown in FIG. 11, one end of the oxygen connection tube 82 may be attached to the low-flow gas inlet port 64, for example, by pushing it around until it is fully and securely attached. The other end of the oxygen connection tube 82 may be connected to the low-flow supplemental oxygen source and then powered on. When the ventilation support device 10 is in a stationary configuration, the compressor power button 46 may be pressed to power on the compressor unit 14. When powered on, the compressor power indicator light 44 may be illuminated to indicate power. For example, a solid green light on the compressor power indicator light 44 may indicate that the compressor is connected to an AC power source (e.g., by connecting to an external power source via the power connection port 74 and the AC power cord), while a solid amber light on the compressor power indicator light 44 may indicate that the compressor is using internal battery power, as described below. In accordance with the power-up sequence of the exemplary embodiment, when the ventilator 12 is turned on by pressing the ventilator power button 20, the ventilator power indicator light 22 may be illuminated. After powering up the compressor unit 14 and ventilator 12, various tests may be performed (e.g., testing the alarm speaker), a start-up screen may be displayed on the display 16, and eventually the display 16 may display a "home" screen (e.g., as described on page 21 of Appendix A).

[0026] The compressor unit 14 may include an internal battery 66 for mitigating temporary power interruptions. The internal battery 66 of the compressor unit 14 may be charged when the compressor unit 14 is connected to an AC power source (e.g., by connection to an external power source via the power connection port 74 and the AC power cord). The internal battery 66 of the compressor unit 14 may have a maximum charge of, for example, two hours. The battery charge indicator 56 may include a series of indicator lights arranged as a battery charge gauge, for example, surrounding the battery charge status button 54, which indicates the current battery charge level of the compressor unit 14 (e.g., as described on pages 22-23 of Appendix A). The battery charge status button 54 may be used, for example, to illuminate the battery charge indicator 56 when the compressor unit 14 is powered off.

[0027] When the ventilation support device 10 is moved to the stationary configuration, the ventilator 12 is docked in the ventilator dock 42 of the compressor unit 14, the compressed gas intake port 40 of the ventilator is fluidly connected to the compressed gas exhaust port 43 of the ventilator dock, the ventilation gas exhaust port 38 of the ventilator is fluidly connected to the ventilation gas intake port 45 of the ventilator dock, and the patient interface gas intake port 81 of the patient interface 80 is fluidly connected to the ventilation gas exhaust port 60 of the compressor unit, such that compressed gas is provided to the ventilator 12 by the compressor unit 14 and the ventilation gas is returned to the compressor unit 14 and then output from the compressor unit 14 to the patient interface 80, for example via the ventilation gas exhaust port 60 of the compressor unit.

[0028] Once the ventilation support apparatus 10 is in the stationary configuration, the compressor unit 14 may be powered off by pressing the compressor power button 46. In accordance with a preferred power-down sequence, the ventilator 12 may then be powered off using the ventilator power button 20, e.g., by pressing the ventilator power button 20 for three seconds and confirming power-off using the display 16 (as described, e.g., on page 25 of Appendix A).

[0029] 12, a schematic diagram of the ventilation support device 10 in an extended range configuration is shown. As mentioned above, the ventilation support device 10 can be used in different operating configurations as the patient's needs change. In the extended range configuration, the ventilator 12 is connected to the compressor unit 14 using a compressed gas hose 84 to enable activities of daily living. The compressed gas hose 84 can be any length of high pressure hose, such as 6 feet or 50 feet. In an exemplary embodiment, the compressed gas hose 84 connects to the compressor unit compressed gas exhaust port 58 of the compressor unit 14 and the ventilator compressed gas intake port 40 of the ventilator 12 via a DISS fitting. However, in other embodiments of the ventilation support device 10 in an extended range configuration, the compressed gas hose 84 may connect the compressor unit compressed gas exhaust port 58 to the ventilator compressed gas intake port 40 according to known or future developed methods.

[0030] 13A and 13B, a front view and a close-up cutaway front perspective view of the ventilator 10 moving from a stationary configuration are shown in two steps, according to an exemplary embodiment. First, after the ventilator 12 is surely powered off (the ventilator 12 can be powered off using the ventilator power button 20), the locking knob 48 on the compressor unit 14 is turned to an unlocked position as shown in FIG. 13A, e.g., a position where a suitable indicator mark on the locking knob 48 faces the unlocked icon 52, at which point the compressor unit 14 pushes the ventilator 12 out. Finally, as shown in FIG. 13B, the ventilator 12 is pulled in a direction to remove the remaining insertion end (e.g., the lower end) of the ventilator 12 from the dock 42 of the compressor unit 14 (e.g., pulled in the direction of the arrow in FIG. 13B) until it is clear of the ventilator dock 42 of the compressor unit 14. In this manner, the ventilator 12 can be undocked from the compressor unit 14.

[0031] 14, a schematic diagram of the connection of the ventilator 12 to the compressor unit 14 via a compressed gas hose 84 in an extended range configuration is shown according to an exemplary embodiment. Connecting the ventilator 12 to the compressor unit 14 via the compressed gas hose 84 allows the ventilator 12 to be used without docking with the compressor unit 14. According to a preferred connection sequence, first ensure that the ventilator 12 is powered off. The compressor unit 14 may be powered off or on. The ventilator 12 is then undocked from the compressor unit 14, for example, by the exemplary method described in connection with FIG. 13. The compressed gas hose 84 is then attached to the compressed gas exhaust port 58 of the compressor unit. For example, in an exemplary embodiment where the compressed gas exhaust port 58 of the compressor unit is a DISS1240 output connection port, the compressed gas hose may be connected to the compressed gas exhaust port 58 of the compressor unit via the DISS connection of the compressed gas hose 84. Finally, the other end of the compressed gas hose 84 is connected to the ventilator compressed gas intake port 40 of the ventilator 12, such as by pushing the small quick connect end into the ventilator compressed gas intake port 40 until it snaps into place.

[0032] 15, a front perspective view of the ventilator 12 is shown illustrating the patient interface 80 and the bottom of the ventilator 12. As shown in FIG 15, in an extended range configuration, the patient interface 80 may be plugged into the ventilation gas exhaust port 38 of the ventilator.

[0033] In an exemplary embodiment, when the ventilation support apparatus 10 is in the extended range configuration, the compressor unit 14 may be powered on by pressing the compressor power button 46, and once powered on, the compressor power indicator light 44 may be illuminated to indicate power in the same manner as when the ventilation support apparatus 10 is in the stationary configuration. For example, a green light on the compressor power indicator light 44 may indicate that the compressor is connected to an AC power source (e.g., by connecting to an external power source via the power connection port 74 and an AC power cord), whereas an amber light on the compressor power indicator light 44 may indicate that the compressor is using internal battery power, as described below. Continuing with the exemplary power-on sequence, the ventilator 12 may be powered on by pressing the ventilator power button 20 in the same manner as when the ventilation support apparatus 10 is in the stationary configuration. Once powered on, the ventilator power indicator light 22 may be illuminated. After powering up the compressor unit 14 and ventilator 12, various tests may be performed (e.g., testing the alarm speaker), a start-up screen may be displayed on the display 16, and the display 16 may eventually display a "home" screen (e.g., as shown on page 33 of Appendix A). As noted above, the compressor unit 14 may include an internal battery 66 to protect against temporary power interruptions. The operation of the internal battery 66, battery charge indicator 56, and battery charge status button 54 of the compressor unit 14 may be the same in the extended range configuration as in the stationary configuration. However, it may be understood that the compressor unit 14 may be powered on or off in alternative manners, such as by user input at the user interface 18 of the ventilator 12, and that the wireless transmitter 31 of the ventilator 12 may communicate with the wireless receiver 79 of the compressor unit 14.

[0034] The ventilator 12 may also include a rechargeable battery 29 for use when the ventilator 12 is undocked from the compressor unit 14, such as when the ventilation support apparatus 10 is within an extended range configuration. The rechargeable battery 29 of the ventilator 12 may be charged when the ventilator 12 is docked with the compressor unit 14. The compressor unit 14 may function as a charging station for the ventilator 12, as described above. The rechargeable battery 29 of the ventilator 12 may be charged in other ways, such as via a ventilator battery charger 86 that connects the ventilator battery charger connection port 32 to a power source, such as a wall outlet or a generator. The rechargeable battery 29 of the ventilator 12 may have a maximum charge of, for example, four hours, and may take approximately three to four hours to fully charge, regardless of whether the ventilator 12 is off or on. When the ventilator 12 is powered on (e.g., via the ventilator power button 20 with the ventilator power indicator light 22 illuminated), a ventilator battery charge icon on the display 16 may indicate the current battery charge level of the rechargeable battery 29 of the ventilator 12 (e.g., as described on page 36 of Appendix A). Referring now to FIG. 16, a schematic diagram of the connection of the ventilator 12 to a ventilator battery charger 86 via a ventilator battery charger cord 88 is shown. The ventilator battery charger cord 88 may be integrally or detachably connected to the ventilator battery charger 86. By connecting the ventilator 12 to the ventilator battery charger 86, the internal battery of the ventilator 12 may be charged without the need to dock the ventilator 12 with the compressor unit 14. According to a preferred connection sequence, the ventilator AC power cord 90 is first connected to the ventilator battery charger 86 and then plugged into an AC power source. Ventilator battery charger cord 88 (connected to ventilator battery charger 86) is then connected to ventilator battery charger connection port 32 on ventilator 12 (e.g., as shown on page 37 of Appendix A).

[0035] 17A and 17B, perspective views are shown illustrating an exemplary process for attaching the ventilator 12 to the belt clip 92 in a two-step process. The belt clip 92 may be used to secure the ventilator 12 so that it can be worn on a belt or waistband, and may include, for example, protrusions that correspond to the belt clip socket 30 on the ventilator 12. First, as shown in FIG. 17A, the belt clip 92 is secured to the belt or waistband by positioning the belt clip 92 on the belt or waistband and pushing down (e.g., in the direction of the arrow shown in FIG. 17A) until the belt clip 92 does not move. Finally, as shown in FIG. 17B, the belt clip 92 may be aligned with the belt clip socket 30 on the ventilator 12, and the ventilator 12 is pushed toward the belt clip 92 until it connects, e.g., the protrusions of the belt clip 92 enter the belt clip socket 30 on the ventilator 12, producing an audible click sound. In this manner, the ventilator 12 may be wearable when the ventilation support apparatus 10 is in the extended range configuration. Alternatively, the ventilator 12 may be mounted to the pole mount 94 in the extended range configuration as described below for a stand-alone configuration. However, it may be understood that there may be numerous schemes for mounting or otherwise using the ventilator 12 in a configuration undocked with a compressor unit 14, and the specific method illustrated should not be construed as limiting the scope of the present disclosure.

[0036] When the ventilation support device 10 transitions to the extended range configuration, the ventilator 12 is not docked to the ventilator dock 42, the compressed gas intake port 40 of the ventilator is fluidly connected to the compressed gas exhaust port 58 of the compressor unit, and the patient interface gas intake port 81 of the patient interface 80 is fluidly connected to the ventilation gas exhaust port 38 of the ventilator, so that compressed gas is provided to the ventilator 12 by the compressor unit 14 and ventilation gas is provided to the patient interface 80 by the ventilator 12 without being returned to the compressor unit 14.

[0037] When the ventilation support system 10 is in the extended range configuration, the ventilator 12 of the exemplary embodiment may be powered off by, in an exemplary embodiment, pressing the ventilator power button 20. In an exemplary embodiment, this may be accomplished by pressing the ventilator power button 20 for three seconds and confirming power off using the display 16 (e.g., as described in Appendix A, page 40). According to an exemplary power off sequence, the compressor unit 14 may then be powered off using the compressor power button 46. Once the ventilator 12 is powered off, the extended range configuration may be terminated by disconnecting the compressed gas hose 84 from the ventilator 12 and the compressor unit 14 (e.g., as described in Appendix A, page 41).

[0038] Referring now to FIG. 18, a schematic diagram of the ventilation support device 10 in a stand-alone configuration is shown. As mentioned above, the ventilation support device 10 can be used in different operational configurations as the patient's needs change. In an exemplary embodiment of the stand-alone configuration, the ventilator 12 is connected to an external compressed gas source 100, such as an air or oxygen gas cylinder (50 PSI and / or less than 40 LPM at 41 PSI) or a wall connection, via a compressed gas hose 84. However, it can be understood that in other embodiments, the external compressed gas source 100 can include any compressed gas source suitable for use with the ventilator 12. In an exemplary embodiment, the ventilator 12 can be interchangeable with medical compressed air or oxygen. However, it can be understood that in certain embodiments, the ventilator 12 can be suitable for use only with one or the other, or with other compressed gases or mixtures of compressed gases.

[0039] When the ventilation support apparatus 10 transitions from the stationary configuration to the standalone configuration, the ventilator 12 may be undocked from the compressor unit 14 in the manner described above in connection with Figures 13A and 13B for transitioning to the extended range configuration. In an exemplary embodiment of the standalone configuration, after the ventilator 12 has been undocked in this manner, the compressor unit 14 may be turned off using the compressor power button 46.

[0040] When the ventilation support apparatus 10 is in a stand-alone configuration, in an exemplary embodiment, the ventilator 12 may be powered on by pressing the ventilator power button 20 in the same manner as when the exemplary ventilation support apparatus 10 is in a stationary or extended range configuration. Upon powering on, the ventilator power indicator light 22 may be illuminated. After powering on the compressor unit 14 and the ventilator 12, various tests may be performed (e.g., testing the alarm speaker), a start-up screen may be displayed on the display 16, and the display 16 may eventually display a "home" screen (e.g., as shown on page 44 of Appendix A). As noted above, the ventilator 12 may include an internal battery 66 for use when the ventilation support apparatus 10 is undocked from the compressor unit 14, such as when the ventilation support apparatus 10 is in an extended range or stand-alone configuration. The operation of the internal battery 66 of the ventilator 12 and the ventilator battery charging icon on the display 16, as well as the use of the ventilator battery charger connection port 32, ventilator battery charger 86, ventilator battery charger cord 88, and ventilator AC power cord 90, may be the same in the standalone configuration as in the extended range configuration (e.g., as described on pages 45-46 of Appendix A). Additionally, in the standalone configuration, the patient interface 80 may be plugged into the ventilator ventilation gas exhaust port 38 in the manner shown in FIG. 15 and described with respect to the extended range configuration.

[0041] When the ventilation support apparatus 10 is in a stand-alone configuration, the ventilator 12 may be attachable to a belt or waistband via a belt clip 92 in the manner described above in connection with Figures 17A and 17B. Alternatively, in either the stand-alone or extended range configuration, the belt clip 92 may be used to secure the ventilator 12 to a pole via a pole mount 94, as described below, although it will be appreciated that other methods of securing the ventilator 12 and other locations at which it may be secured may be implemented without departing from the scope of this disclosure.

[0042] 19A-19C, perspective views are shown illustrating an exemplary embodiment of how the ventilator 12 is secured to a pole via a belt clip 92 and a pole mount 94 in a process having three steps. First, as shown in FIG. 19A, the pole mount 94 is positioned around the pole in a desired orientation and secured to the pole. In the example shown in FIG. 19A-19C, the pole mount 94 includes a vice clamp 96 that can be tightened around the pole by turning a knob 98, thereby securing the pole mount 94 to the pole. Next, as shown in FIG. 19B, the belt clip 92 is slid into a hole at the top of the pole mount 94 until it is secured and pressed down (e.g., in the direction of the arrow shown in FIG. 19B). Finally, the belt clip 92 is aligned with the belt clip socket 30 on the ventilator 12 and the ventilator 12 is pressed toward the belt clip 92 until it is connected, e.g., until the prongs of the belt clip 92 enter the belt clip socket 30 on the ventilator 12, producing an audible click.

[0043] 20A-20C, perspective (FIGS. 20A and 20B) and top (FIG. 20C) views of an exemplary embodiment of how the ventilation support apparatus 10 transitions to a stand-alone configuration by connecting the ventilator 12 to an external compressed gas source 100 in an exemplary process having three steps are shown. First, with the ventilator 12 turned off (the ventilator power button 20 may be used to turn off the ventilator 12), the oxygen regulator 102 is connected to the external compressed gas source 100 as shown in FIG. 20A, for example, by sliding the oxygen regulator 102 over the neck of an oxygen cylinder (external compressed gas source 100), aligning the pins on the oxygen regulator 102 with the holes in the neck, and tightening the T-screw on the oxygen regulator 102 by turning a handle. Next, as shown in FIG. 20B, the compressed gas hose 84 is connected to the oxygen regulator 102, for example, to the DISS connector end of the oxygen regulator 102. Finally, as shown in Figure 20C, after turning on the gas supply in accordance with the preferred method of using the external compressed gas source 100 and oxygen regulator 102, the other end of the compressed gas hose 84 is connected to the ventilator 12, such as by pushing the small quick connect end onto the compressed gas intake port 40 of the ventilator until it snaps into place. The external compressed gas source 100 may then be replaced, for example, as described in Appendix A, page 53.

[0044] In the exemplary embodiment depicted in Figures 20A-20C, the external compressed gas source 100 is an oxygen cylinder and a compressed gas hose 84 and an oxygen regulator 102 are used. However, it will be appreciated that in other embodiments, the external compressed gas source 100 may be different, such as another gas or gas mixture other than oxygen, a portable gas compressor, or another oxygen source such as an oxygen concentrator. If the external compressed gas source 100 is an air cylinder, another hose, such as an air hose, may be used in place of the compressed gas hose 84 and another suitable regulator may be used in place of the oxygen regulator 102.

[0045] When the ventilation support apparatus 10 transitions to a standalone configuration, the ventilator 12 is not docked to the ventilator dock 42, the ventilator's compressed gas intake port 40 is fluidly connected to the external compressed gas source 100, and the patient interface gas intake port 81 is fluidly connected to the ventilator's ventilation gas exhaust port 38, such that compressed gas is provided to the ventilator 12 by the external compressed gas source 100, and ventilation gas is provided by the ventilator 12 to the patient interface 80 without passing through the compressor unit 14.

[0046] When the exemplary embodiment ventilation support apparatus 10 is in a standalone configuration, the ventilator 12 may be powered off by pressing the ventilator power button 20 in the same manner as in the extended range configuration, e.g., pressing the ventilator power button 20 for three seconds and confirming power off using the display 16 (e.g., as described on page 40 of Appendix A). Once the ventilator 12 is powered off, the standalone range configuration may be exited by disconnecting the compressed gas hose 84 from the ventilator 12 and the external compressed gas source 100.

[0047] As described above, the ventilator 12 may include a wireless transmitter 31 and the compressor unit 14 may include a wireless receiver 79. In any of the above configurations (e.g., stationary, extended range, or stand-alone), the compressor 83 of the compressor unit 14 may be controllable by signal transmission from the wireless transmitter 31 to the wireless receiver 83 initiated by user input at the user interface 18. In this manner, a patient or other user of the ventilator 12 may wirelessly control the ventilation support device 10 regardless of whether the ventilator 12 is docked with the compressor unit 14 or not. Signal transmission between the wireless transmitter 31 and the wireless receiver 83 may follow any wireless communication standard known in the art. Alternatively, the ventilator 12 may communicate with the compressor unit 14 by a wired connection, in which case the wireless transmitter 31 and the wireless receiver 79 may be omitted. However, it will be appreciated that wireless communication can be advantageous in that the ventilator 12 can be configured to control all electronically controllable aspects of the ventilation support apparatus 10 in all configurations, without requiring a separate control group on the compressor unit or the presence of a wired signal link.

[0048] The ability of device 10 to be used in any of the above configurations is due in part to the structural and functional features of its electromechanical pneumatic system, which is under the control of a microprocessor. A pneumatic schematic of this system is provided in Appendix A, page 142. Also provided in Appendix A, page 142, are the general performance specifications of device 10 for use in each of the above configurations.

[0049] The above description is provided by way of example and not by way of limitation. In light of the above disclosure, those skilled in the art may devise variations that do not depart from the scope and spirit of the invention disclosed herein. Furthermore, the various features of the embodiments disclosed herein may be used alone or in different combinations with each other, and are not intended to be limited to the specific combinations described herein. Thus, the claims are not limited by the exemplary embodiments.

[0050] As an example, it is contemplated that alternative versions of the ventilation support apparatus 10 may be provided that are adapted for use only in stationary and extended range configurations, and not necessarily in a stand-alone configuration. In such variations, the structure and on-board control algorithms / software corresponding to such stand-alone configuration functionality may be eliminated in the ventilation support apparatus 10. It is also contemplated that alternative versions of the ventilation support apparatus 10 may be provided that eliminate features such as the low flow gas inlet port 64 in the compressor unit 14, along with its ancillary structural and functional / control features. In this case, by eliminating the low flow gas inlet port 64, and thus eliminating the ability to directly introduce oxygen, etc., into the compressor unit 14 via the low flow gas inlet port 64, it is further contemplated that such variations of the ventilation support apparatus 10 may be used in conjunction with a patient interface configured to allow for the introduction of oxygen, etc., from a suitable source directly into such patient interface.
