[0002] Respiratory humidification therapy devices are used to deliver high-flow mixed gases that have been heated and humidified to patients to improve blood oxygen saturation and respiratory symptoms. Existing respiratory humidification therapy devices include a host, an automatic humidification water box, a heated breathing circuit, a patient interface, an oxygen connection tube, and other components. Air and oxygen are drawn into the pipeline, measured by an oxygen concentration sensor and a flow sensor, and then sent to the automatic humidification water box through a one-way valve. After the gas is heated and humidified in the water box, it enters the heated breathing circuit to maintain the temperature.

[0003] However, the existing respiratory humidification therapy device can only realize the function of humidifying gas, but cannot realize the atomization function, that is, the drug is atomized and delivered into the patient's airway together with the humidified gas. Users can only perform drug treatment through a separate nebulizer. For example, the patent announcement number is CN212940912U, and the patent name is an electrical adapter and a humidification therapy device using the electrical adapter. It discloses a humidification therapy device including the above-mentioned electrical adapter, a host connected to the air inlet adapter tube of the electrical adapter, a humidification box connected to the air inlet adapter tube and the air outlet adapter tube at the same time, and a heating pipeline connected to the air outlet adapter tube, and the air inlet electrical terminal is connected to the host; however, the electrical adapter does not have a port for connecting the nebulizer, and the atomization function cannot be realized during use;

The first positioning portion 17 and the second positioning portion 18 have positioning portions for limiting the wire 43 .

[0082] Regarding the connection between the second positioning portion 18 and the wire 43, specifically, a connecting terminal 431 is provided at one end of the wire 43, and the connecting terminal 431 has a fixed section and a connecting section 4311. The second positioning portion 18 has an opening, and the width of the fixed section is greater than the width of the opening so that the fixed section is located on one side of the opening, and the connecting section 4311 extends from the opening to the outside of the shell 42.

[0083] In this embodiment, as a preferred embodiment, the second positioning portion 18 of the second interface 6 includes a second round rod, and a second opening groove is formed on one side of the second round rod along the axial direction;

[0084] It is worth noting here that the second opening groove has an opening on the side facing the first opening groove, and the width of the opening is greater than the width of the fixed section of the connecting terminal 431. The purpose is to prevent the fixed section from passing too far out of the second opening groove as the fixed section passes upward from the bottom of the second opening groove, and to further limit the fixed section so that the connecting section 4311 can be extended to be fixedly connected with other devices, thereby avoiding instability of the fixed section when connected to other devices. Therefore, the width of the opening is greater than the width of the fixed section.

[0085] It is worth noting here that the second round rod is a hollow cylindrical structure with a cross-section. The second round rod can be a straight rod or a rod-shaped structure with a certain degree of curvature. When the second round rod has a certain degree of curvature, it is to be suitable for the case where there is a certain angle between the first interface 5 and the second interface 6 so that the second round rod is connected between the first interface 5 and the second interface 6, which is more in line with the transition direction between the first interface 5 and the second interface 6.

[0086] When in use, the connecting section 4311 of the connecting terminal 431 of the wire 43 is directly inserted into the second opening groove along the radial direction of the second opening groove of the second round rod, and the fixed section is located outside the second opening groove. Since the fixed section is restricted outside the bottom of the second opening groove due to its width being greater than the width of the opening of the second opening groove, the connecting section 4311 is positioned outside the top of the second opening groove. The connecting section 4311 is fixed to facilitate stable connection with other devices, preventing the connecting section 4311 from deviation or tilting or misalignment during use, which may cause looseness during connection with other devices.

[0087] In this embodiment, as another preferred embodiment, the second positioning portion 18 has a positioning ring, which is sleeve-connected in the circumferential direction of the second interface 6, and a raised limiting piece is provided on one side of the mounting ring, and the limiting piece has an opening inside, and the width of the opening is greater than the width of the fixed section of the connecting terminal 431, so that the fixed section is limited by the opening and cannot extend out of the top of the opening, and can only be located outside the bottom of the opening, so that the connecting section 4311 is extended out of the top of the opening to be electrically connected to other devices.

[0088] As a preferred embodiment, in order to enable the fixing section of the connecting terminal 431 to be smoothly connected to the second positioning portion 18 , one of the second positioning portion 18 and the fixing section has a guide rib 19 , and the other has a guide groove matching the guide rib 19 .

The cross-section of the guide rib 19 can be a rectangular structure or an arc structure, protruding from the outer circumferential surface of the first terminal or the second terminal; a guide groove is provided on one side of the fixed section that cooperates with the guide rib 19, and the guide groove is cooperatively connected with the guide rib 19.

[0090] When in use, the guide groove of the fixed section is clamped on the guide rib 19 and moved upward along the extension direction of the guide rib 19 to connect the fixed section to the second positioning portion 18. When the fixed section moves to the opening position, the top surface of the fixed section is abutted against the bottom surface of the opening, so that the top surface of the fixed section is limited outside the bottom surface of the opening, and the connecting section 4311 extends through the opening to outside the top surface of the opening.

[0091] Regarding the connection between the first positioning portion 17 and the wire 43, as a preferred embodiment, the wire 43 also has a fixed terminal 432, the first positioning portion 17 is connected to the first interface 5, the first positioning portion 17 is provided with a mounting groove 8 connected to the fixed terminal 432, and the fixed terminal 432 is plugged and fixed to the mounting groove 8.

[0092] Further, a buckle 9 is provided on the outer side of the fixed terminal 432; the buckle 9 is elastic, and / or a matching groove for matching with the buckle 9 is provided on the inner wall of the mounting groove 8. The first positioning portion 17 has a mounting seat connected to the first interface 5 and protruding from the first interface 5, and the mounting seat is provided with a mounting groove 8 in the upward direction.

[0093] When an elastic buckle 9 is provided on the outer side of the fixed terminal 432, during use, the buckles 9 on both sides of the fixed terminal 432 are pressed by the thumb and index finger respectively to fit it to the side of the fixed terminal 432, and then the fixed terminal 432 is inserted into the mounting groove 8 from the top of the mounting groove 8 along the extension direction of the mounting groove 8. When the insertion end of the buckle 9 is inserted into the mounting groove 8, the thumb and index finger are released and no longer press the buckle 9, and the buckle 9 is reset in the mounting groove 8. Then, under the elastic force of the buckle 9, the fixed terminal 432 is plugged and connected with the mounting groove 8.

[0094] As another preferred embodiment, the first positioning portion 17 of the first interface 5 includes a first round rod, a first opening groove is formed on one side of the first round rod along the axial direction, the first round rod is a hollow cylindrical structure, and the first round rod is a straight rod structure. When in use, the fixed terminal 432 of the wire 43 can be directly inserted from the first opening groove into the first buckle groove.
