    An alternative approach to clearing mucus plugs and / or other debris from the trachea includes the use of a suction catheter. As will be appreciated, the suction catheter is a flexible long tube connected at one end to the breathing tube. The other end of the suction catheter is connected to a collection container (suction canisters) and a breathing device that generates suction. Critically ill or injured patients using a breathing tube (endotracheal) tube or a tracheal tube typically need occasional suction to remove secretions from the airways. The respiratory therapist, nurse, or ICU telemic can suck the patient by inserting the suction catheter into the breathing tube to keep the breathing tube free of secretions and prevent obstruction of the airways. Furthermore, the frequency of suction is determined by the amount of secretion that the patient produces. The trachea is sucked as fluid builds up in the lungs. Unfortunately, the use of such a suction catheter is a painful procedure known to create trauma in the patient.
    Furthermore, some other techniques involve manual detection of airway obstructions followed by manual determination of changing settings on the ventilator to facilitate clearance of airway obstructions. However, this procedure is laborious and time consuming, causing increased discomfort to the patient.
    It may therefore be desirable to develop an embodiment of a method which can be configured to advantageously assist in automatically releasing any obstructions from the trachea associated with the patient, thereby increasing the clinical workload and reducing the patient's discomfort. More specifically, it may be desirable to reduce the frequency of clinical intervention to clear obstructions in the trachea, thereby minimizing patient discomfort.
    In accordance with aspects of the present art, there is provided a ventilation system comprising a ventilator, a breathing tube connectable to the ventilator, the breathing tube having a patient branch, a blockage releasing module configured to automatically release a blockage from the patient branch by controlling an inhalation fate. exhalation fate or a combination thereof.
    DRAWINGS These and other features, aspects and features of the present invention will be better understood when the following detailed description is read with reference to the accompanying drawings in which like characters throughout represent like parts throughout the drawings, in which: FIG. 1 is a block diagram of a ventilation system configured to automatically release obstructions from a breathing tube in accordance with aspects of the present art; FIG. 2 is a block diagram of an embodiment of a ventilation system according to FIG. 1 in accordance with aspects of the present art; FIG. 3 is a flow chart illustrating an example of a method of releasing obstructions from a breathing tube using the example of a ventilation system according to FIG. 1; FIG. 4 is a flow chart illustrating an example of a method of initiating the release of obstructions from a breathing tube using the example of a ventilation system in FIG. 1.
    FIG. 5 is a flow chart illustrating an example of a clot-releasing maneuver for releasing obstructions from a trachea; and FIG. 6 is a fate diagram illustrating an example of a method for controlling inhalation fate and / or exhalation fate for releasing obstructions from a respiratory tract.
    DETAILED DESCRIPTION FIG. 1 is a block diagram of an example of a ventilation system 10 which may be configured to assist in filling one or more obstructions from a breathing tube, wherein the breathing tube may be disposed of in a patient 12 in accordance with aspects of the present art. In other words, the exemplary ventilation system 10 can be configured to assist a traditional ICU ventilator in releasing obstructions from a patient 12, thereby improving clinical workflow by bypassing the use of suction and / or suction catheters to release airway obstruction and minimize patient discomfort 12. .
    In general, the ventilation system 10 may be operatively connected to a patient 12 via a breathing tube.
    Unfortunately, a commonly encountered problem while using the trachea includes clogging of the trachea. More specifically, the trachea may become clogged by a mucus plug and / or debris thereby causing discomfort to the patient 12 and reducing the efficiency of the ventilation system 10. According to exemplified aspects of the present technique, a module is configured to advantageously assist a traditional ventilation system with automatic release of any blockages in the respiratory tract. Further shown in FIG. 1 the ventilation system 10 as operatively coupled to the patient 12. In one embodiment, the ventilation system includes a fan 14, such as an ICU fan. As will be appreciated, the ICU ventilator is a machine that may be configured to assist the patient 12 with breathing through a tube, such as a breathing tube 18, which is typically inserted into the tract of the patient 12 via the mouth or nose of the patient 12, the breathing tube 18 being operatively connected to the ICU ventilator 14. It can be noted that the terms breathing tube and breathing circuit can be used interchangeably. Furthermore, the ICU fan 14 may also include a first connection 20 and a second connection 22. The first connection 20 and the second connection 22 may be configured to assist in operatively connecting the ICU fan 14 to the patient 12 via the breathing tube 18.
    As noted above, the patient 12 may be operatively connected to the ICU ventilator 14 via the breathing tube 18. The breathing tube 18 may include an inhalation branch 24 and an exhalation branch 26 in an embodiment illustrated in FIG. 1, the breathing tube 18 is shown as being operatively connected to the first connection 20 of the ICU ventilator 14 via the inhalation branch 24. The ICU ventilator 14 may be configured to pump gas into the lungs of the patient 12 through the inhalation branch 24. Similarly, the breathing tube 18 is also shown as being operatively connected to the second connection 22 of the ICU ventilator 14 via the exhalation branch 26. The ICU ventilator 14 may be configured to assist in inhalation of gas from the lungs of the patient 12 through the exhalation branch 26.
    In general, the trachea 18 may be inserted through the mouth of the patient 12 and advanced into the patient's lu fi pathways until a distal end (not shown in FIG. 1) of the trachea 18 passes through the patient's larynx (not shown in FIG. 1). As will be appreciated by those in the art, the breathing tube 18 may be clogged or blocked by a blockage (not shown in FIG. 1). The blockage may, for example, include a mucus plug and / or other debris. Furthermore, clogging can pose a serious health risk to patient 12 and / or cause discomfort to patient 12. Furthermore, clogging can also reduce the efficiency of the ventilation system 10.
    According to exemplary aspects of the present art, the ICU ventilator may include a clog release module 16 configured to assist the ICU ventilator to automatically release any obstructions from the breathing tube 18. In a presently considered configuration, the ICU ventilator 14 is shown as including a clogging module 16. However, In some other embodiments, the plug release module 16 may include a stand-alone module configured for use with a ventilation system, such as the fan system 10 (see FIG. 1). The operation of the plug release module 16 will be described in greater detail with reference to FIG. 3-5. Furthermore, the ventilation system 10 may also include a pressure grinding subsystem 28 which may be configured to assist in measuring pressure on lu lu pumped into the patient 12. Turning now to FIG. 2 which illustrates a diagram of an embodiment 30 of the ventilation system 10 according to FIG. 1. As previously noted with reference to FIG. 1, a ventilator, such as the ICU ventilator 14 (see FIG. 1), may be operatively connected to the patient 12 via, for example, the breathing tube 18.
    Furthermore, the ICU fan 14 may include a first connection 20 (see FIG. 1) and a second connection 22 (see FIG. 1), the first connection 20 being configured to receive the inhalation tube 24 of the breathing tube 18 while the second connection 22 may be configured to receive the exhalation tube 26 of the breathing tube 18 as previously noted. Furthermore, the breathing tube 18 may also include a Y coupling 32, a patient branch 34 and a user interface 36. It may be noted that the user interface 36 is part of the breathing tube 18 which is directly connected to the patient 12. In some embodiments, the user interface 36 may include a tracheal tube or an endotracheal tube. In the embodiments shown in FIG. 2, the user interface 36 is shown as including an endotracheal tube. However, it should be understood that other known devices may also be implemented for the user interface 36.
    As noted above with reference to FIG. 1, the endotracheal tube 36 may be inserted through the patient's mouth and inserted into the patient's airways until a distal end 38 of the endotracheal tube 36 passes through the patient's larynx (not shown in FIG. 2). Furthermore, the endotracheal tube 36 may be closed or blocked by a blockage 40, blockages 40 may include, for example, a mucus plug and / or other debris. According to exemplary aspects of the prior art, the ICU ventilator 14 may include the occlusion release module 16 configured to assist the ICU ventilator in automatically releasing any occlusions, such as the occlusion 40, from the breathing tube 18 as previously noted with reference to FIG. 1.
    Currently available technology typically involves manual operation to clear the trachea 18 of any obstructions, the manual operation may include a suction maneuver and / or use of a suction catheter. However, the use of currently available technology results in elevated levels of patient discomfort. Therefore, it may be desirable to develop a method configured to automatically occlude obstructions from the respiratory tract 18, thereby reducing patient discomfort and improving clinical work fate.
    FIG. 3 is a flow chart 60 depicting an exemplary method of releasing a blockage from a breathing tube such as the breathing tube 18 (see FIG. 1). In a presently contemplated configuration, the occlusion release module 16 (see FIG. 1) may be configured to assist the ICU ventilator (see FIG. 1) in performing the exemplary method of releasing an obstruction from the trachea. The method starts with step 62 where one or more blockages in a breathing tube can be detected. As previously noted, airway obstruction may include mucus plugs and / or other debris. Once a blockage in the trachea is detected, a trigger signal may be generated, as indicated by step 64, where the trigger signal may be indicative of detected blockages. In some embodiments, the trigger signal may include an alarm signal, where the alarm signal may be configured to alert hospital personnel, such as a clinician or a nurse, in the presence of a blockage in the respiratory tract.
    Then, at step 66, an operation for automatically releasing the occlusion from the respiratory tract can be initiated. It can be noted that although FIG. 3 depicts the method of automatically releasing the obstruction from the trachea as including optional steps 62-64, the method of automatically releasing the obstruction from the respiratory tract can also start at step 66. In other words, the maneuver for automatic releasing of the obstruction from the respiratory tract can be automatically initiated even at lack of the triggering signal. More specifically, in some embodiments, the actuation of clearance from the trachea may be executed periodically, while the actuate release of obstruction from the respiratory tract in certain other embodiments may be continuously executed.
    Step 66 can be better understood with reference to FIG. Referring now to FIG. 4, depicting a flow chart of the process of step 66 (see FIG. 3). As noted above, the obstruction of the airway obstruction can be manually initiated by the clinician or automatically initiated. Thus, the method can start at step 72 where a state of execution of releasing maneuver can be detected. Furthermore, in accordance with aspects of the present art, the clogging release can be initiated either manually or automatically. Thus, at step 74, a check may be performed to verify whether the state for executing the clogging release operation includes a manual state. At step 74, if it is verified that the state for executing the clogging release operation includes a manual state, the clogging release operation can be initiated manually, as depicted in step 76.
    However, if it is verified at step 74 that the state for executing the clogging operation does not include a manual state, another check may be performed at step 78 to verify whether the state for executing the clogging operation includes an automatic state. . At step 78, if it is verified that the condition for executing the clogging release operation includes an automatic condition, the clogging release operation may be initiated automatically as indicated in step 80. In one embodiment, the clogging release module 16 (see FIG. 1) configured to automatically trigger execution of the clogging release. Furthermore, in accordance with exemplified aspects of the present art, in the state of automatic use, the clogging release maneuver may be executed continuously as indicated in step 82. Alternatively, the clogging release actuator may also be executed periodically as is shown in step 84. In the periodic state for executing the clog release maneuver, the maneuver can be executed periodically at predetermined time intervals. Referring again to FIG. 3, once the condition for executing the clog-releasing maneuver is detected in steps 72-74 (see FIG. 4), the clog-releasing maneuver can be executed as indicated in step 68. As noted above, the clog-releasing maneuver may be configured to assist in the release of any obstruction in the trachea associated with the patient 12 (see FIG. 1.). 5.
    Turning now to FIG. 5 illustrating a fate diagram 90 depicting the exemplary method of releasing one or more obstructions from a breathing tube connected to a patient. The method starts at step 92 where an inhalation fate, an exhalation fate, or a combination thereof can be controlled in order to facilitate automatic release of one or more obstructions from the trachea. As previously noted, the breathing tube, such as the breathing tube 18 (see FIG. 1), can be configured to operatively connect a patient such as the patient 12 (see FIG. 1) to a ventilator system such as an ICU ventilator 14 (see FIG. 1).
    More specifically, in step 92 in accordance with exemplified aspects of the present technique, the inhalation fate, exhalation flow, or a combination thereof, may be controlled so that a maximum exhalation fate is greater than a maximum inhalation fate to facilitate automatic release of obstructions from the trachea. Step 92 can be better understood with reference to FIG. 6.
    FIG. 6 is a flow chart depicting the exemplary method of controlling inhalation fate, exhalation fate, or a combination thereof, to automatically release the occlusion from the respiratory tract. More specifically, the inhalation fate and / or exhalation flow can be controlled so that a maximum exhalation fate during an exhalation phase of a patient's exhalation cycle (see FIG. 1) is greater than a maximum inhalation fate during an inhalation phase of the patient's respiratory cycle.
    The method starts at step 102 where an inhalation fate can be lowered to assist in reducing the release of occlusion into the patient 12 (see FIG. 1). More specifically, the inhalation fate during an inhalation phase of a breathing cycle of the patient 12 can be lowered. The inhalation fate can be reduced during the inhalation phase of the breathing cycle by temporarily switching off the airway distance compensation during the inhalation phase. Furthermore, a pressure increase time can also be increased to assist in lowering the inhalation fate during the inhalation phase. Furthermore, as indicated in step 104, an exhalation fate may also be increased to assist in releasing the obstruction from the trachea. In other words, the exhalation rate during an exhalation phase of the patient's breathing cycle can be increased. More specifically, the exhalation output during the exhalation phase can be increased while the inhalation output during the inhalation phase can be lowered so that the maximum exhalation output is greater than the maximum inhalation output as indicated by reference number 106.
    It can be noted that the presence of any blockages in the respiratory tract can unfavorably result in increased resistance in the respiratory tract. Thus, in one embodiment, the ICU ventilator 14 (see FIG. 1) may be configured to compensate for the increased resistance in the trachea by lowering an airway pressure target to a value below a positive final exhalation pressure (PEEP) thereby increasing the exhalation under during the exhalation phase of the patient 12. In accordance with aspects of the present art, the pressure mesh subsystem 28 (see FIG. 1) may be used to monitor the lung pressure associated with the patient 12. More specifically, the pressure measurement subsystem 28 may be used to monitor the lung pressure to ensure that the lung pressure does not fall below a predetermined level. PEEP value.
    Furthermore, in accordance with further aspects of the present art, the exhalation under during the exhalation phase can be increased by actively aspirating gas from the lungs of the patient 12, thereby facilitating active exhalation of gas from the lungs of the patient 12. In some embodiments, a High Frequency Oscillating Ventilator (HFOV) ) systems (not shown in FIG. 1) are used to assist the active exhalation of gas from the lungs of the patient 12, thereby facilitating increased exhalation fate during the exhalation phase.
    In accordance with further aspects of the present art, a suction subsystem (not shown in FIG. 1) may be used to assist in lowering the pressure in the trachea more rapidly than conventional means. It can be noted that the use of the suction subsystem can also assist in lowering the pressure in the breathing tube to negative pressure values. Again, the pressure measuring subsystem 28 can be used to ensure that the lung pressure does not fall below the predetermined PEEP value. Furthermore, in accordance with aspects of the present art, any obstructions in the trachea may be released from the trachea and into waterfalls in the trachea. Referring again to FIG. 5, as a consequence of step 92, the obstruction in the respiratory tract can be released out of the respiratory tract and, for example, into the water traps of the respiratory tract. In order to ensure that the detected blockage has actually moved out of the respiratory tract, it may be desirable to monitor the release of the blockage out of the respiratory tract. Thus, the release of the obstruction from the respiratory tract can be monitored, as indicated in step 94. In one embodiment, the release of obstructions from the respiratory tract can be monitored by monitoring the tubular resistance of the respiratory tract. Alternatively, waveform patterns for fate and pressure can also be monitored to monitor the release of obstructions from the trachea.
    In some other embodiments, a combination of respiratory resistance monitoring and waveguide pattern monitoring for fate and pressure may be used to assist in overseeing the release of the airway obstruction. Thus, a check can be performed at step 96 to determine if the occlusion has been released from the trachea, when the ventilator system 8se FIG. l), and more specifically the ICU fan 14 (see FIG. 1) may return to a previous operating state as indicated in step 98. In other words, once the clogging release operation has been successfully executed, the ICU fan 14 may return to the previous one. operational condition. In one embodiment, the prior operative condition of the ICU ventilator 14 may include providing artificial ventilation to the patient. Furthermore, the airway resistance compensation, which has been temporarily switched off, can be resumed. The pressure rise time can also, as previously noted, be increased to assist in lowering the inhalation fate during the inhalation phase while executing the clogging operation. Again, once the occlusion is released from the inhalation tube, the present pressure rise time can be reset to the value of the pressure rise time used prior to the execution of the occlusion release maneuver. It can be noted that step 96, if it is verified that the occlusion has not been removed from the trachea, then control can return to 92 where inhalation flow and / or exhalation fate can be regulated to release the occlusion out of the respiratory tract.
    While only certain features of the invention have been illustrated and described herein, many modifications and changes will occur to those skilled in the art. It is to be understood, therefore, that the appended claims are intended to cover all such modifications and changes as fall within the scope of the invention.
