Referring to fig. 1 and 5, a ventilation therapy device according to a preferred embodiment of the present invention, which may be a transnasal high flow humidification oxygen therapy apparatus or a ventilator, includes a main body 1, a humidification tank 2 detachably connected to the main body 1, and a first adapter 3 or a second adapter 4 selectively connected to the humidification tank 2. As shown in fig. 8, the main unit 1 has a main unit air outlet 11, and when the humidification tank 2 and any one of the first adapter 3 and the second adapter 4 are mounted on the main unit 1, the main unit air outlet 11 is communicated to the inner cavity of the humidification tank 2 through the first adapter 3 or the second adapter 4, so as to introduce the respiratory gas to be humidified into the inner cavity.

As shown in fig. 2 to 4, the first adapter 3 for the ventilation therapy device has a first air inlet tube 31, and the filter element 5 is connected to the first air inlet tube 31. Under the state that the first adapter 3 is connected to the humidification tank 2, the main machine air outlet 11 is communicated with the inner cavity of the humidification tank 2 through the filter element 5 and the first air inlet pipe 31. In contrast, as shown in fig. 6 and 7, the second adapter 4 includes a second air inlet pipe 41, and in a state where the second adapter is connected to the humidification tank 2, the main unit air outlet 11 is connected to the second air inlet pipe 41 and communicates with the inner cavity of the humidification tank 2 through the second air inlet pipe 41. It can be seen that the second adapter 4 may be similar to the existing adapter, and the second air inlet pipe 41 extends from the humidification tank 2 to the host air outlet 11 of the host 1 and is directly connected to the host air outlet 11, so as to directly introduce the air output from the host air outlet 11 into the inner cavity of the humidification tank 2 for humidification, and the air is not filtered.

Compare with this second adapter 4, can reserve the space that holds filter core 5 between the first intake pipe 31 of this first adapter 3 and the host computer gas outlet 11 of host computer 1 when humidification jar 2 is connected first adapter 3, perhaps set up filter core 5 on the extension route of this first intake pipe 31, can filter the gas of 11 outputs in the host computer gas outlet from this, and then the humidification in the inner chamber that lets in humidification jar 2 through first intake pipe 31, satisfy special disease demand. Therefore, the ventilation treatment equipment of the utility model can be connected with the first adapter 3 or the second adapter 4 on the selective humidification tank 2, is flexibly suitable for different patients and can be normally used under different conditions. Under the condition, the first adapter 3 ensures that the ventilation treatment equipment can meet different use requirements under the state of not replacing the main machine 1, reduces equipment purchasing cost of hospitals, saves social resources and better meets different requirements of patients. Meanwhile, the first adapter 3 which is disposable is arranged, so that the clinical use efficiency of the equipment can be improved.

By comparison, it can be seen that in order to facilitate the connection of the filter element 5, the first adapter 3 and the second adapter 4 are different in structure and their respective relative connection relationship with the humidification tank 2. In a preferred embodiment, the distance between the connection position of the first air inlet pipe 31 and the humidification tank 2 and the air outlet 11 of the main machine (in the state that the first adapter 3 is connected to the humidification tank 2) when the first adapter 3 is adopted is larger than the distance between the connection position of the second air inlet pipe 41 and the humidification tank 2 and the air outlet 11 of the main machine (in the state that the second adapter 4 is connected to the humidification tank 2) when the second adapter 4 is adopted. From this, can make humidifying jar 2 rotatory certain angle relative host computer 1 when using different adapters to adapt to the change of first adapter 3 relative second adapter 4, reserve the space that holds filter core 5. In other embodiments, the first air inlet pipe 31 of the first adapter 3 may be shortened by a certain length relative to the second air inlet pipe 41 of the second adapter 4, and the filter element 5 may also be connected to the first air inlet pipe 31, so that the distance between the connection position of the first air inlet pipe 31 and the humidification tank 2 and the main unit air outlet 11 does not need to be increased by rotating the humidification tank 2 relative to the main unit 1. Or, the humidification tank 2 may be provided with air inlets corresponding to the first adapter 3 and the second adapter 4, respectively, and when one of the first adapter 3 and the second adapter 4 is adapted, the air inlet corresponding to the other is plugged, and the distance between the connection position of the first air inlet pipe 31 and the humidification tank 2 and the air outlet 11 of the host machine may be increased.

Generally, to facilitate assembly, the adapter is integrally provided with an inlet pipe and an outlet pipe. In a preferred embodiment of the present invention, as shown in fig. 2 to 4, the first adapter 3 may include a first air outlet pipe 32 integrally connected to a first air inlet pipe 31. In the state that the first adapter 3 is connected to the humidification tank 2, the first air outlet pipe 32 is also communicated with the inner cavity of the humidification tank 2, so that the first air outlet pipe can be used for connecting an air vent pipeline to deliver humidified air to a patient. As shown in fig. 6 and 7, the second adapter 4 may include a second outlet pipe 42 integrally connected to a second inlet pipe 41, and in a state where the second adapter 4 is connected to the humidification tank 2, the second outlet pipe 42 is also communicated with the inner cavity of the humidification tank 2, so as to be used for connecting a ventilation pipeline to deliver humidified gas to a patient.

The first air inlet conduit 31 may have a horizontally extending section extending towards the main unit air outlet 11, thereby facilitating connection to the main unit air outlet 11 (via the filter cartridge 5). As mentioned above, by rotating the humidification tank 2 relative to the main unit 1, the distance between the connection position of the first air inlet pipe 31 and the humidification tank 2 and the air outlet 11 of the main unit can be relatively increased to have a space for accommodating the filter element 5. In this case, the extending direction of the first inlet pipe 31 and the first outlet pipe 32 relative to the humidification tank 2 is also different from that of the second adapter 4. For ease of understanding, referring first to fig. 5 and 6, the horizontal extension of the second inlet pipe 41 and the second outlet pipe 42 of the second adapter 4 extends in a direction substantially perpendicular to a line between the respective connection locations of the second inlet pipe 41 and the second outlet pipe 42 to the humidification tank 2, thereby having a relatively short air flow path from the main body 1 to the humidification tank 2. In contrast, as shown in fig. 1 and 2, in a state where the first adapter 3 is connected to the humidification tank 2, an angle between a line connecting the first inlet pipe 31 and the first outlet pipe 32 to the humidification tank 2 and a horizontally extending section thereof is acute, whereby a space for accommodating the filter cartridge 5 is provided between the first inlet pipe 31 and the main unit air outlet 11.

As mentioned above, the filter element 5 can be arranged on the extension of the first inlet duct 31 or connected to the free end of the first inlet duct 31. When connected to the free end of the first air inlet pipe 31, the main air outlet 11 can be directly connected to the filter element 5 and is communicated with the inner cavity of the humidification tank 2 through the filter element 5 and the first air inlet pipe 31 in sequence. In order to secure the connection sealability, one of the first air inlet pipe 31 and the filter cartridge 5 may be formed as an inner conical joint at one end connected to each other, and the other may be formed as an outer conical joint capable of being fitted with the inner conical joint. For example, the first gas inlet pipe 31 may have an inner conical surface with a diameter of 22 at the end facing the filter element 5, and the filter element 5 may have an outer conical surface matching the inner conical surface, so that the outer conical surface can be inserted into the inner conical surface of the first gas inlet pipe 31 to achieve a sealed connection, thereby ensuring reliable connection and gas tightness.

Generally, the first adapter 3 or the second adapter 4 can be connected to the humidification tank 2 in advance, and then mounted to the main body 1 together with the humidification tank 2. In order to well position the installation position of the humidification tank 2 on the host 1 and ensure reliable connection of the gas circuit, the preferred embodiment of the utility model also provides a positioning and matching structure of the first adapter 3 or the second adapter 4 and the host 1.

Referring to fig. 8, the main body 1 may be provided with a positioning groove 12 for positioning the first outlet duct 32 and the second outlet duct 42, and a positioning groove 13 may be formed in the positioning groove 12. Accordingly, as shown in fig. 4, an end of the first outlet pipe 32 of the first adapter 3 far from the humidification tank 2 may be provided with a first positioning hook 32a, and/or, as shown in fig. 6 and 7, an end of the second outlet pipe 42 of the second adapter 4 far from the humidification tank 2 may be provided with a second positioning hook 42 a. Thus, as shown in fig. 9, when the first adapter 3 is applied, the first positioning hook 32a can cooperate with the limiting groove 13 in the positioning groove 12 to limit the first adapter 3 and the humidification canister 2 connected thereto to be detached from the main body 1; similarly, when the second adapter 4 is applied, the second positioning hook 42a can cooperate with the limiting groove 13 in the positioning groove 12 to limit the second adapter 4 and the humidification tank 2 connected thereto from being detached from the host 1.

In the illustrated preferred embodiment, the first and second positioning hooks 32a and 42a are bent upward to be hooked to the stopper groove 13 of the main body 1. For this purpose, the first adapter 3 or the second adapter 4 connected to the humidification tank 2 mounted on the main unit 1 can be automatically hooked into the limiting groove 13 by providing an elastic mechanism. For this purpose, an elastic element (e.g. a spring) may be arranged in the supporting seat 14 of the main machine 1 for supporting the humidification tank 2 (the supporting seat 14 may be, for example, a heating plate for heating water in the humidification tank 2), so as to push the humidification tank 2 supported thereon to move upwards by the elastic force of the elastic element until the first positioning hook 32 of the corresponding first adapter 3 or the second positioning hook 42 of the second adapter 4 is hooked into the limiting groove 13. Here, the hooking amount of the first positioning hook 32 or the second positioning hook 42 and the limiting groove 13 may be 0.5mm to 5mm, such as 1mm, so as to facilitate the disassembly and assembly operation of the humidification tank 2.

In the illustrated preferred embodiment, the first positioning hook 32a or the second positioning hook 42a is engaged with the limiting groove 13 to limit the wetting tank 2 from being separated from the main body 1 in the horizontal direction. Correspondingly, the humidification tank 2 can be installed to the main machine 1 along the horizontal direction, and for this purpose, a horizontally extending humidification tank guide rail 15 can be arranged on the main machine 1, so that the humidification tank 2 can be installed to the main machine (1) along the humidification tank guide rail 15. In other embodiments, the limiting groove 13 may be arranged to limit the movement of the first adaptor 3 and the second adaptor 4 in other directions, depending on different or different positioning requirements of the installation of the humidification tank 2.

The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto. The technical idea of the utility model within the scope, can be right the utility model discloses a technical scheme carries out multiple simple variant, makes up with any suitable mode including each concrete technical feature. In order to avoid unnecessary repetition, the present invention does not separately describe various possible combinations.
