[0002] The ventilator pipeline components are divided into adapters, heating pipelines, patient interfaces and water tanks; the adapters of the ventilator are used to connect the main unit, water tank and heating pipeline. The water tank humidifies the gas output by the main unit and outputs the gas with a certain humidity to the patient interface through the heating pipeline to achieve efficient respiratory treatment. However, the existing adapters and heating pipelines are configured separately and cannot be assembled as a whole accessory and equipment. When used, the adapters and breathing pipelines need to be installed separately, which is less convenient to operate. Furthermore, the existing adapters contain electrical parts, which makes it inconvenient to disinfect the product after repeated use. Liquid leakage into the adapters can easily cause electrical risks, and the safety of the equipment is relatively low.

[0045] The present application relates to a ventilator adapter tube, comprising an air inlet adapter tube and an air outlet adapter tube, the air inlet adapter tube having a first interface portion that can be connected to an air outlet of a host and a second interface portion that can be connected to an air inlet of a humidifier tank; the air outlet adapter tube having a third interface portion that can be connected to an air outlet of a humidifier tank and a fourth interface portion that can be connected to a heating pipeline, and also comprising an electrical terminal mounting position on which a heating pipeline terminal can be detachably mounted, the electrical terminal mounting position being arranged at the first interface portion and being configured so that the heating pipeline terminal can be docked and cooperated with the host 1 synchronously with the first interface portion.

[0046] The ventilator adapter tube serves as a connector for connecting the main unit 1, the humidifier tank, and the heating pipeline. The gas output by the main unit is humidified by the humidifier tank, and then output to the patient interface through the heating pipeline after having a certain humidity for the patient to inhale. Traditionally, a wire is required to be arranged inside the adapter tube for heating the gas output by the main unit 1. However, the adapter tube contains electrical components, which may make it difficult or impossible to clean the adapter tube, and may easily damage the wires and have the risk of electrical connection, thereby reducing the user experience and installation performance. In this application, the wiring terminal and the electrical terminal mounting position arranged at the first interface portion are detachable. The detachable connection avoids the problem that the traditional adapter tube is respectively provided with electrical terminals at the first interface part and the fourth interface part, and the wiring is run inside the adapter body, which leads to complex structure, high cost, and cannot be reused; the heating pipeline of the present application is detachably connected or fixedly connected to the heating pipeline through a wiring harness, and is no longer connected to the inside of the adapter tube, so that the gas is directly heated inside the heating pipeline, and the gas can be heated while flowing along the moving path of the heating pipeline, which not only realizes more uniform gas heating, but also can realize the cleaning of the adapter tube, so that the service life of the adapter tube is extended and the safety performance is enhanced.

[0047] Specifically, the air inlet switching tube and the air outlet switching tube of the ventilator switching tube are respectively located on both sides. The air inlet switching tube is used to humidify the gas output from the air outlet of the main unit 1 and circulate it into the heating pipeline. Therefore, the air inlet switching tube has a first interface portion connected to the air outlet of the main unit 1, and the gas output from the air outlet of the main unit 1 flows into the air inlet switching tube through the first interface portion; the air inlet switching tube also has a second interface portion connected to the air inlet of the humidification tank, and the air outlet switching tube also has a third interface portion connected to the air outlet of the humidification tank. The second interface and the third interface portion can mix the steam of the humidification tank with the gas output from the air outlet of the main unit 1 to increase the humidity of the gas output from the air outlet of the main unit 1, so that the gas output from the air outlet of the main unit 1 has a certain humidity. The gas with a certain humidity enters the heating pipeline through the fourth interface portion of the air outlet switching tube 2 connected to the heating pipeline and is output to the patient interface for use by the patient.

[0048] When in use, the wiring terminal is detachably connected to the electrical terminal mounting position of the first interface part, so that the wiring terminal and the host 1 can be quickly disassembled and assembled, and the wiring terminal is connected in the electrical terminal mounting position, so that when the first interface part is connected to the host 1, the electrical connection between the wiring terminal and the host 1 can be achieved at the same time, which can effectively protect the wiring terminal so that the wiring terminal is hidden in the mounting position to prevent pollution such as dust, and can also improve the convenience of installation, and realize quick installation and disassembly through simple plugging and unplugging, further simplifying the operating steps of medical staff, improving the use efficiency, realizing rapid treatment, and can also effectively fix the wiring terminal to ensure the installation position of the wiring terminal, and prevent the instability of the connection between the wiring terminal and the host 1, which makes the device unusable.

[0049] Preferably, the electrical terminal installation position is a slot provided on the wall portion of the first interface portion, and the slot is oriented toward an extension direction of the first interface portion.

[0050] The heating pipeline is connected to the wiring terminal, and the inside of the adapter tube is no longer connected to the wiring terminal. The wiring terminal is led out from the heating pipeline and connected to the host 1 through the adapter tube. Since the path passed by the wiring terminal is long, the wiring terminal part between the heating pipeline and the host 1 needs to be fixed. Therefore, an electrical terminal mounting position is provided at the first interface part of the adapter tube. The electrical terminal mounting position can make the structure of the card slot or other structures. When the electrical terminal mounting position is in the form of a card slot, the wiring terminal is connected to the card slot by card connection. When the wiring terminal needs to be uninstalled for cleaning the adapter tube, the wiring terminal can be directly pulled out of the card slot. The detachable connection between the electrical terminal and the adapter tube is achieved through simple plugging and unplugging operations, further realizing quick assembly and disassembly, reducing the operating difficulty of medical staff, and improving the convenience of use. When the user is in urgent need of treatment, the assembly and disassembly time can be shortened, thereby improving the efficiency of use.

[0051] As a preferred embodiment, the heating pipeline terminal of the first interface part is electrically connected to the heating pipeline through a wiring harness; the adapter tube also includes a adapter body connected between the air inlet adapter tube and the air outlet adapter tube, and the adapter body is provided with a wiring harness clamping position.

[0052] The air inlet transfer tube and the air outlet transfer tube are respectively located on both sides of the transfer tube, and a transfer body is connected between the air inlet transfer tube and the air outlet transfer tube. A wire harness clamping position for connecting the wiring terminal is provided on the transfer body. The wiring terminal is connected to the heating pipeline through the wire harness. The wire harness extends from the inside of the heating pipeline to the outside of the heating pipeline, so that the wiring terminal is detachably connected to the installation position of the electrical terminal, and is synchronously connected to the host 1 with the first interface part. Therefore, the part of the wire harness extending outside the heating pipeline needs to pass through the transfer body to be connected to the host 1. In order to fix the wire harness and further position the wiring terminal, a wire harness clamping position for connecting the wire harness is provided on the transfer body;

[0053] When in use, one end of the wiring harness is connected to the inside of the heating pipeline, and the other end of the wiring harness with the wiring terminal extends to the outside of the heating pipeline. The wiring harness extending to the outside is inserted into the wiring harness clamping position and is detachably connected to the wiring harness clamping position of the adapter body. The wiring terminal is installed in the electrical terminal installation position of the first interface part and is synchronously connected to the main unit 1 with the first interface part. When not in use, first unplug the first interface part from the main unit 1, and then remove the wiring harness from the wiring harness clamping position. If the wiring harness needs to be replaced or the heating pipeline needs to be replaced, the wiring harness connected to the heating pipeline can be detached from the heating pipeline. The present application can realize rapid disassembly and assembly of the wiring terminal, facilitates installation and disassembly, and has high portability.

[0054] The present application also relates to a high-flow ventilator pipeline assembly, comprising an output pipeline 3 and a transfer tube 2; the transfer tube 2 is used to connect the output pipeline 3 to the host 1, and the output pipeline 3 is used to output the gas output by the host 1; the output pipeline 3 has a heating component 4 for heating the gas inside; the protruding end of the heating component 4 extends outward from the inside of the output pipeline 3 and is connected to the host 1 through the transfer tube 2; the transfer tube 2 is provided with a mounting position for connecting the heating component 4.

[0055] The ventilator pipeline assembly includes an output pipeline 3 and an adapter tube 2 connected to the output pipeline 3. The adapter tube 2 and the output pipeline 3 can be assembled with other equipment as a whole, avoiding the traditional output pipeline 3 and the adapter tube 2 being two separate parts, which need to be assembled separately during installation. The ventilator pipeline assembly of the present application can shorten the assembly time and improve the convenience of use; wherein the output pipeline 3 is internally connected to a heating component 4, and the heating component 4 is no longer located inside the adapter tube 2. The heating component 4 is located inside the output pipeline 3 so that the gas can be evenly heated when flowing along the output pipeline 3, and the adapter tube 2 is clearer and more convenient because it does not contain electrical parts inside; when the output pipeline 3 is internally connected to the heating component 4, one end of the heating component 4 is connected to the output pipeline 3, and the other end needs to extend out The output pipeline 3 is connected to the main unit 1 to further position the heating component 4, avoid incorrect installation, and avoid the path of the heating component 4 being too long, resulting in chaotic wiring and the heating component 4 being unable to be fixed. Direct docking with the main unit 1 will cause the part where the heating component 4 and the main unit 1 are docked to shake and tilt under the action of external forces, resulting in a decrease in the connection stability between the heating component 4 and the main unit 1. Therefore, the heating component 4 extends out of the output pipeline 3 and passes through the adapter tube 2 to be detachably connected to the adapter tube 2, so that the heating component 4 between the output pipeline 3 and the main unit 1 is fixed. By providing an installation position on the adapter tube 2 for detachably connecting the heating component 4, quick assembly and disassembly between the output pipeline 3 and the adapter tube 2, the main unit 1 and the heating component 4 is further realized, thereby reducing the difficulty of operation for medical staff and improving the efficiency of clinical treatment.

[0056] Preferably, the heating assembly 4 comprises a connecting wire body 41 and a wire connector 42 connected to the protruding end of the connecting wire body 41; the wire connector 42 is provided with a connecting buckle 10 connected to the mounting position.

[0057] The connecting wire body 41 of the heating component 4 has a connecting end and an extending end, the connecting end is used to connect with the inside of the output pipeline 3, the connecting wire body 41 is connected to the inner wall of the output pipeline 3 along the axial direction of the output pipeline 3, and the extending end of the connecting wire body 41 extends out of the output pipeline 3, the extending end of the connecting wire body 41 is connected with a wire connector 42, the end of the wire connector 42 has an electrical terminal for electrically connecting with the host 1, and one side of the wire connector 42 along the width direction has a connecting buckle 10 connected to the mounting position;

[0058] When in use, the connecting end of the connecting wire body 41 is connected to the inside of the output pipeline 3, and the protruding end of the connecting wire body 41 protrudes out of the output pipeline 3 along the axial direction of the output pipeline 3 and is connected to the wire connector 42. The wire connector 42 is inserted into the installation position, and the connecting buckle 10 on one side of the width direction of the wire connector 42 is snap-connected with the installation position. The end of the wire connector 42 is flush with the end of the adapter tube 2 facing the main unit 1, and the end of the wire connector 42 is synchronously connected to the main unit 1 with the adapter tube 2.

[0059] Preferably, the transfer tube 2 includes a through-connected pipe joint 21 and a main unit joint 22; one end of the pipe joint 21 has a first interface 5 connected to the output pipeline 3, and the other end of the pipe joint 21 has a second interface 6 connected to the air outlet of the humidification tank; the main unit joint 22 has a main unit interface 19 connected to the air outlet of the main unit 1, and a third interface 7 connected to the humidification tank 20.

[0060] Specifically, the pipe connector 21 is used to connect to the output pipeline 3, and the host connector 22 is used to connect to the host 1; the gas output from the air outlet of the host 1 enters the host connector 22 through the host interface 19, and the moisture in the humidification tank 20 enters the pipe connector 21 through the second interface 6, and enters the host connector 22 through the third interface 7 to mix with the gas output from the air outlet of the host 1, thereby increasing the humidity of the gas, so that the humidified gas enters the output pipeline, is heated, and then is output to the patient interface.

[0061] The present application does not make any specific limitation on the setting of the installation position, and any one of the following implementations may be adopted:

[0062] Embodiment 1: The host connector 22 has a first tube wall 8 and a second tube wall 9, an air flow channel is formed inside the first tube wall 8, and the gas output from the host outlet flows along the first tube wall 8.

[0063] The connecting wire body 41 extends from the inside of the output pipeline 3 to the outside of the output pipeline 3, and is synchronously connected to the host 1 through the pipeline joint 21 and the host joint 22. The first tube wall 8 and the second tube wall 9 of the host joint 22 are coaxially sleeved, wherein the first tube wall 8 is located on the inner side of the second tube wall 9, and the first tube wall 8 is connected to the gas outlet of the host 1, and is used to allow the gas flowing out of the gas outlet of the host 1 to enter the pipeline joint 21 through the first tube wall 8.

The protrusion is an elastic block, so that when the wire connector 42 is installed along the opening groove, when the protrusion moves to the position of the groove, the protrusion can be reset and connected to the groove under the action of elastic force, and the side of the protrusion is limited by the side wall of the groove, thereby enabling the fixing buckle 11 and the connecting buckle 10 to be snap-connected, so that the wire connector 42 is connected to the host connector 22.

[0065] When in use, the connecting wire body 41 is inserted into the open groove and extended to the outside of the open groove along the length direction of the open groove so that the end of the wire connector 42 is flush with the end of the open groove. The open groove serves as the wire channel 12 of the connecting wire body 41, which can guide and position the connecting wire body 41. A fixing buckle 11 is arranged in the open groove. When the connecting wire body 41 is inserted into the wire channel 12, the connecting buckle 10 moves to the position of the fixing buckle 11 and the connecting buckle 10 is connected with the fixing buckle 11 to fix the connecting wire body 41 to the host connector 22; when disassembling, the connecting buckle 10 is disconnected from the fixing buckle 11, and the connecting wire body 41 is pulled out along the wire channel 12, so that the connecting wire body 41 is separated from the host connector 22, further realizing the detachable connection of the heating component 4 in the transfer tube 2, improving the rapid disassembly and assembly between the heating component 4 and the ventilator pipeline, and further improving the convenience of the user.

[0066] Embodiment 2: a socket 13 is provided in the installation position, and the extended end of the heating component 4 passes through the socket 13 and enters the interior of the adapter tube 2 to be connected to the host 1 .

[0067] The side of the host connector 22 is provided with a socket 13 that passes through the interior. The wire connector 42 of the heating component 4 is inserted into the socket 13 and extends to the interior of the adapter tube 2, and then the wire connector 42 is electrically connected to the host 1. The socket 13 serves as a connection channel between the wire connector 42 and the host 1, which can fix the connecting wire body 41 to prevent confusion in the wiring. It can also partially hide the connecting wire body 41, so that part of the connecting wire body 41 is hidden in the interior of the adapter tube 2 through the socket 13. When disassembling, the wire connector 42 can be directly pulled out of the socket 13. There is no heating component 4 inside the adapter tube 2, which is convenient for cleaning. The direct plug-in and unplug method makes the connection between the heating component 4 and the host 1 and the ventilator pipeline easier, further improving the user experience.

[0068] Preferably, the output pipeline 3 includes a pipeline body 31 and a pipe head 32 connected to each other; the pipe head 32 is connected to the pipe joint 21 of the adapter tube 2; and the connecting end of the heating component 4 is connected to the pipeline body 31 .

[0069] The pipeline body 31 of the output pipeline 3 is used to connect with the patient interface, and the pipe head 32 of the output pipeline 3 is used to connect with the pipe joint 21. The airflow flows along the pipeline body 31 and is evenly heated during the flow, so the heating component 4 is connected to the pipeline body 31.

[0070] The specific connection method between the pipe head 32 and the pipe joint 21 is not limited by the present embodiment, and any of the following embodiments can be adopted:

[0071] Embodiment 1: The outside of the pipe head 32 is provided with a connecting buckle 14 ; the outside of the pipe joint 21 is connected with a connecting block 15 , and the connecting buckle 14 is connected in cooperation with the connecting block 15 .

[0072] The middle part of the connecting buckle 14 is hingedly connected to the outer side surface of the pipe head 32, and the side of the connecting buckle 14 facing the pipe head 32 has a V-shaped barb. A connecting block 15 is provided on the outer side of the pipe joint 21 at a position corresponding to the connecting buckle 14, and the inner side of the connecting block 15 has a limiting groove. When the pipe head 32 is connected to the top of the pipe joint 21 downward, the top of the connecting buckle 14 is pressed so that the barb at the bottom of the connecting buckle 14 can enter the limiting groove and be connected to the limiting groove for clamping connection, thereby realizing the clamping connection between the pipe head 32 and the pipe joint 21.

[0073] Embodiment 2: The tube head 32 and the output pipeline 3 are welded and connected to form an integrated structure, which can be synchronously connected to the host 1 during use. When disassembling, there is no need to separate the output pipeline 3 and the tube head 32 separately. The transfer tube 2 can be directly pulled out from the host 1, thereby realizing rapid assembly and disassembly of the host 1 and the ventilator pipeline.

[0074] As a preferred implementation, the host 1 further has a power interface 16 separated from the air outlet of the host 1 , and the wire connector 42 is connected to the power interface 16 .

[0075] Traditionally, the air outlet of the host 1 and the power interface 16 are set to the same port, and the wire connector 42 is connected to the host connector 22 and synchronously docked with the air outlet of the host 1 at the end of the host connector 22; in order to achieve functional zoning so that the user can more clearly distinguish the air outlet and the power interface 16, the power interface 16 can be separated from the air outlet of the host 1, further protecting the power interface 16, avoiding water vapor contamination of the power interface 16 so that the power interface 16 becomes electrically connected, thereby enhancing the safety of the device.

[0076] The power interface 16 of the host 1 is used to insert the wire connector 42 of the heating component 4 into the power interface 16 to achieve electrical connection between the heating component 4 and the host 1, thereby heating the gas in the output pipeline 3.

[0077] As a preferred embodiment, a sensor placement position 17 for connecting a sensor is provided along the circumferential direction of the interface of the host 1 .

[0078] A sensor installation position is set in the circumferential direction of the host 1 interface used for connecting to the air outlet of the host 1. Specifically, the host connector 22 includes a first tube wall 8 and a second tube wall 9. A cavity is formed between the first tube wall 8 and the second tube wall 9. A mounting position for installing a wire connector 42 is provided in the cavity, and a sensor mounting position for installing a sensor is provided. The sensor is installed in the sensor mounting position to facilitate detection of the gas flow at the gas outlet of the host 1, changes in the humidity and temperature of the gas, to achieve stable control of the temperature and humidity of the gas, to provide the patient with optimal temperature and humidity treatment, and to further improve the user experience.

[0079] As a preferred embodiment, the output pipeline 3 is provided with a wire clamp 18 for clamping to the device.

[0080] Since the path of the output pipeline 3 is relatively long, during clinical use, the output pipeline 3 occupies a relatively large area. The pipeline is laid on the ground or bed surface, which may easily cause pipeline confusion. In addition, the gas outlet port of the output pipeline 3 is connected to the patient interface. Since the output pipeline 3 is relatively long and the installation is unstable, it may easily cause shaking at the interface with the patient interface, resulting in gas leakage. Therefore, in order to facilitate the fixation of the output pipeline 3, a wire clamp 18 is connected to the outer circumferential surface of the output pipeline 3. The wire clamp 18 can clamp the output pipeline 3 to other equipment, such as a bedside railing or a bedside railing, to facilitate use by medical staff and patients.

[0081] The present application also relates to a ventilator, comprising a host 1, and also comprising the above-mentioned high-flow ventilator pipeline assembly; the host 1 is provided with an air outlet, and the adapter tube 2 is detachably connected to the host 1, so that the host 1 has a first state in which the air outlet is connected to the third port, and a second state in which the air outlet is connected to the air outlet pipeline.

[0082] The detachable connection between the adapter tube 2 and the host 1 avoids the traditional integrated design of the adapter tube 2 and the host 1, which requires the pipe interface in the adapter tube 2 to be sealed by means of a cap when not in use. When not in use, the adapter tube 2 can be directly pulled out from the host 1, thereby achieving quick assembly and disassembly between the adapter tube 2 and the host 1, reducing the operating difficulty for medical staff, improving the efficiency of medical staff, and making the equipment more portable. When the host 1 or the adapter tube 2 is damaged, it can be replaced and repaired in time, thereby reducing the cost of use.

[0083] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0084] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0085] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
