Description

Technical Field

[0001] This application relates to the field of air supply pipeline technology for respiratory equipment, and more particularly to a multi-position airway structure and respiratory therapy device. Background Technology

[0002] Currently, ventilators are mainly used in treatment facilities or home bedrooms. Traditional ventilators have a fixed air outlet orientation; for example, the humidifier canister or breathing circuit tubing (which connects directly to the ventilator unit and the user) is on the left, and the ventilator unit is on the right. If the user's location on the ventilator is changed, requiring the humidifier canister or breathing circuit tubing to be moved from the left to the right, the entire ventilator's orientation needs to be adjusted. In treatment environments, treatment cabinets or stands typically hold multiple devices; adjusting the ventilator's orientation necessitates adjusting the oxygen inlet tubing, making it inconvenient to use.

[0003] Therefore, existing technologies have defects and shortcomings, and need further improvement and development. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide a multi-installation airway structure and respiratory therapy device, which aims to solve the problem that the outlet direction of the ventilator in the prior art is fixed, resulting in the ventilator adjustment and the relative position of the patient remaining unchanged.

[0005] The technical solution adopted by this application to solve the technical problem is as follows: a multi-position airway structure for installing humidifiers in different positions on a ventilator, comprising: Gas source connection section, the gas source connection section is used to connect to a gas supply source; A plurality of gas supply branches, each of the plurality of gas supply branches having a gas supply inlet end and a gas supply outlet end, each of the plurality of gas supply inlet ends being connected to the gas source connection section, each of the plurality of gas supply outlet ends being located in different directions, and each of the plurality of gas supply outlet ends being used to connect to a humidification tank or a breathing circuit pipe. A number of solenoid valves are provided one-to-one on a number of the gas supply branches, and each of the solenoid valves is used to control the on / off state of the corresponding gas supply branch.

[0006] Optionally, the number of the gas supply branches is set to two groups, and the gas supply outlets of the two groups of gas supply branches are set at a 180° angle.

[0007] Optionally, the number of the gas supply branches is set to three groups, and the gas supply outlets of the three groups of gas supply branches are set at a 90° angle.

[0008] Optionally, the airway structure further includes a transfer pipe for connecting the air source connection section and the plurality of air supply inlets, wherein the height of the inner wall of the transfer pipe increases from the direction of the air source connection section and the plurality of air source connection sections, and smoothly transitions with the plurality of air source connection sections.

[0009] Optionally, the inner diameter of the adapter pipe increases from the direction of the gas source connection section and the plurality of gas source connection sections.

[0010] Optionally, some of the gas supply outlets are further provided with auxiliary fixing components, which are used to assist in fixing the humidification tank or the breathing circuit tube.

[0011] Optionally, the auxiliary fastener includes: An auxiliary fixing plate is provided, which is detachably connected to a respiratory therapy device. The auxiliary fixing plate has an interface fixing hole for fixing the air supply outlet end and for fixing the breathing circuit tube.

[0012] Optionally, the auxiliary fastener further includes: a plurality of quick-connect slots, the plurality of quick-connect slots being evenly arranged on the auxiliary fixing plate, and the plurality of quick-connect slots being used for quick connection to the humidification tank; Some of the quick-connect slots are configured as snap-fit, bolt, or magnetic fasteners.

[0013] Optionally, heating wires and ultraviolet disinfection components are installed in several gas supply branches.

[0014] The technical solution adopted by this application to solve the technical problem is as follows: a respiratory therapy device, which includes the airway structure as described above.

[0015] Compared with existing technologies, this application provides a multi-installation airway structure and respiratory therapy device. The airway structure sets up several air supply branches in parallel at different locations after the air source connection section, and equips each air supply branch with a solenoid valve for independent on / off control. This allows the humidifier or breathing circuit tubing to be quickly switched and installed in different locations as needed, without rotating the main unit or modifying the original pipelines. This significantly improves the flexibility and adaptability of the device in treatment cabinets and home settings. At the same time, by closing idle air supply branches, the risk of air leakage and unnecessary energy consumption are reduced, while the gas flow and pressure stability of the open air supply branches are ensured. This shortens the installation and adjustment time, reduces the complexity of nursing operations, improves the ease of use of the device, thereby increasing user compliance and ensuring treatment continuity.

Detailed Implementation

[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0019] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] The main application scenarios for ventilators are treatment facilities or home bedrooms. When in use, the air outlet needs to be placed on the side closest to the user to facilitate the indirect and safe arrangement of medical equipment. However, in actual use scenarios, especially in treatment environments, sometimes it is necessary to directly connect the user and the ventilator unit with a breathing circuit tube, and sometimes it is necessary to place a humidifier between the ventilator unit and the user. In addition, there are usually more than one instrument on the treatment cabinet or treatment frame. Adjusting the direction of the ventilator also requires adjusting the oxygen inlet tube, which makes the use of the ventilator inconvenient. To facilitate the adjustment of ventilator tubing, this application provides a multi-position airway structure and respiratory therapy device. The airway structure features several air supply branches connected in parallel at different locations after the air source connection section, with each branch equipped with a solenoid valve for independent on / off control. This allows the humidifier or breathing circuit tubing to be quickly switched and installed in different locations as needed, without rotating the main unit or altering existing pipelines. This significantly improves the flexibility and adaptability of the device in treatment cabinets and home settings. Simultaneously, by closing idle air supply branches, the risk of air leakage and unnecessary energy consumption is reduced, while ensuring the flow and pressure stability of the open air supply branches. This shortens installation and adjustment time, reduces the complexity of nursing operations, and improves the ease of use and continuity of treatment. See the following embodiments for details.

[0022] Please refer to the following: Figures 1 to 4 The first embodiment of this application provides a multi-installation airway structure 10 for use on a ventilator, so that a humidifier canister 20 can be installed in multiple positions on the ventilator. The airway structure 10 includes an air source connection section 11, a plurality of air supply branches 12, and a plurality of solenoid valves 13. The air source connection section 11 is used to connect to an air supply source. Each of the plurality of air supply branches 12 has an air supply inlet end 121 and an air supply outlet end 122. Each of the plurality of air supply inlet ends 121 is connected to the air source connection section 11, and the plurality of air supply outlet ends 122 are located in different positions. The plurality of air supply outlet ends 122 are used to connect to the humidifier canister 20 or the breathing circuit tube. The plurality of solenoid valves 13 are correspondingly arranged on the plurality of air supply branches 12, and each of the plurality of solenoid valves 13 is used to control the on / off state of the corresponding air supply branch 12.

[0023] It is understandable that the airway structure 10, by setting several air supply branches 12 in parallel at different locations after the air source connection section 11, and equipping each air supply branch 12 with a solenoid valve 13 to independently control its on / off state, allows the humidifier 20 or breathing circuit tubing to be quickly switched and installed in different locations as needed, without rotating the main unit of the equipment or modifying the original pipelines, significantly improving the flexibility and adaptability of the layout in treatment cabinets and home settings; at the same time, by closing the idle air supply branches 12, the risk of air leakage and unnecessary energy consumption are reduced, and the flow and pressure stability of the opened air supply branches 12 are ensured, thereby shortening the installation and adjustment time, reducing the complexity of nursing operations, and improving the ease of use of the equipment and the continuity of treatment.

[0024] In some specific embodiments, the number of the gas supply branches 12 is set to two groups, and the gas supply outlet ends 122 of the two groups of gas supply branches 12 are set at a 180° angle. That is, the two groups of gas supply branches 12 are 180° opposite each other, and with the selective on / off of the solenoid valve 13, the on / off of the gas supply branches 12 in the left and right relative positions can be achieved with one key, without rotating the main unit of the equipment or modifying the pipeline, reducing interference with the side-mounted instruments, keeping the pipeline with small bends and stable pressure drop, shortening the installation and maintenance time, and adapting to the placement requirements of treatment cabinets and bedrooms.

[0025] In some other specific embodiments, the number of the gas supply branches 12 is set to three groups, and the gas supply outlet ends 122 of the three groups of gas supply branches 12 are set at a 90° angle. It can be seen that the three groups of gas supply branches 12 are distributed at 90°, and combined with the selective on / off of the solenoid valve 13, they can cover the installation positions on the left side, front side, and right side of the ventilator, without moving the main unit of the equipment or changing the pipeline, reducing bends and interference, and maintaining stable flow.

[0026] In some embodiments, the air duct structure 10 further includes a connecting pipe 14, which connects the air source connection section 11 and the plurality of air supply inlet ends 121. The inner wall height of the connecting pipe 14 increases from the direction of the air source connection section 11 and the plurality of air source connection sections 11, and the connecting pipe 14 smoothly transitions with the plurality of air source connection sections 11. By setting the connecting pipe 14 to connect the air source connection section 11 and the plurality of air supply inlet ends 121, and making the inner wall height of the connecting pipe 14 increase along the airflow direction and smoothly transition with the plurality of air source connection sections 11, the gas resistance of the air supply branch 12 can be effectively reduced, turbulence can be weakened, and noise can be reduced. Furthermore, the connecting pipe 14 is integrally formed with the plurality of air source connection sections 11.

[0027] In some embodiments, the inner diameter of the transfer pipe 14 increases from the gas source connection section 11 and the plurality of gas source connection sections 11. This can effectively avoid turbulence, ensure a more balanced flow when switching between different directions, thereby reducing noise and condensation, ensuring stable gas supply to the humidification tank 20, and reducing energy consumption.

[0028] In some embodiments, several of the gas supply outlet ends 122 are further provided with auxiliary fixing members 15, which are used to assist in fixing the humidification tank 20 or the breathing circuit tube. It can be seen that by adding auxiliary fixing members 15 to the gas supply outlet ends 122 on the basis of multi-directional gas supply, the humidification tank 20 or the breathing circuit tube can be quickly and securely installed, improving the stability of the installation of the humidification tank 20 or the breathing circuit tube and reducing the risk of vibration and pull-off detachment of the humidification tank 20 or the breathing circuit tube.

[0029] In some embodiments, the auxiliary fixing component includes an auxiliary fixing plate 151 and a plurality of quick-connect slots 153. The auxiliary fixing plate 151 is used for detachable connection to the respiratory therapy device. The auxiliary fixing plate 151 has an interface fixing hole 152 for fixing the air supply outlet end 122 and the breathing circuit tube. It can be seen that by providing the detachable auxiliary fixing plate 151 and the interface fixing hole 152, the air supply outlet end 122 and the breathing circuit tube can be easily connected.

[0030] In some embodiments, the auxiliary fixing component further includes a plurality of quick-connect slots 153, which are evenly arranged on the auxiliary fixing plate 151. Each of the quick-connect slots 153 is used for quick connection of the humidification tank 20, facilitating connection between the air outlet end 122 and the breathing tubing. By providing the quick-connect slots 153, tool-free quick assembly, disassembly, and position switching of the humidification tank 20 are achieved, while simultaneously improving the connection stability of the humidification tank 20. Furthermore, the quick-connect slots 153 may be configured as snap-fit, bolt, or magnetic fixing components.

[0031] In other embodiments, each of the gas supply branches 12 is equipped with a heating wire and an ultraviolet disinfection component. The heating wire and ultraviolet disinfection component in each gas supply branch 12 can be individually controlled to be turned on or off, thereby enabling the gas in the gas supply branch 12 to be heated and disinfected.

[0032] A second embodiment of this application provides a respiratory therapy device, including the airway structure 10 as provided in the first embodiment of this application. It is understood that the respiratory therapy device provided in this embodiment has multiple air supply outlets 122 with different functional orientations, thereby allowing for quick and safe adjustment of the relative position of the humidifier 20 according to the relative position of the user and the respiratory therapy device, and ensuring the safe operation of the respiratory therapy device.

[0033] In summary, this application provides a multi-position airway structure and a respiratory therapy device. The multi-position airway structure includes an air source connection section for connecting to an air supply source; a plurality of air supply branches, each having an air supply inlet and an air supply outlet, each air supply inlet being connected to the air source connection section, and each air supply outlet being located in a different position for connecting to a humidifier or a breathing circuit tube; and a plurality of solenoid valves, each corresponding to one of the air supply branches, each used to control the on / off state of the corresponding air supply branch. The airway structure features several air supply branches connected in parallel at different locations after the air source connection section, with each branch equipped with a solenoid valve for independent on / off control. This allows the humidifier or breathing circuit tubing to be quickly switched and installed in different locations as needed, without rotating the main unit or altering existing pipelines. This significantly improves the flexibility and adaptability of the layout in treatment cabinets and home settings. At the same time, by closing idle air supply branches, the risk of air leakage and unnecessary energy consumption is reduced, while ensuring the flow and pressure stability of the open air supply branches. This shortens installation and adjustment time, reduces the complexity of nursing operations, and improves the ease of use of the equipment and the continuity of treatment.

[0034] It should be understood that the application of this application is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
