[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a multifunctional respiratory intervention endotracheal tube adapter, including a tube body 1, the top of the tube body 1 is fixedly connected to a connecting tube 2, the bottom of the tube body 1 is fixedly connected to a connecting tube 2 3, the middle of the tube body 1 is provided with a through groove connected to the connecting tube 1 2 and the connecting tube 2 3, and the shape of the through groove is approximately a step-shaped. Through the shape setting inside the tube body 1, it is ensured that there is no obstruction in the transmission between the two connected pipes, so as to achieve the effect of preventing part of the liquid from being blocked by the protrusion at the connection. The tube body 1, the connecting tube 1 2 and the connecting tube 2 3 are jointly provided with a fixing mechanism 4.

[0032] Reference Figure 1 - Figure 3 The fixing mechanism 4 includes a pneumatic chamber 41, the inner wall piston of the pneumatic chamber 41 is connected to a control block 42, one end of the control block 42 close to the center of the tube body 1 is elastically connected to the inner wall of the pneumatic chamber 41 through a spring 43, one end of the spring 43 is fixedly connected to the end of the control block 42 close to the center of the tube body 1, and the other end of the spring 43 is fixedly connected to the inner wall of the pneumatic chamber 41, the outer wall of the connecting tube 2 is fixedly connected to an airbag 44, the shape of the airbag 44 is annular, and the interior of the airbag 44 is connected to the interior of the pneumatic chamber 41, and the outer wall of the connecting tube 23 is fixedly connected to an airbag 2 45, the shape of the airbag 2 45 is annular, and the interior of the airbag 2 45 is connected to the inner wall of the pneumatic chamber 41.

[0033] Reference Figure 1 - Figure 3 The outer wall of the tube body 1 is slidably connected with a push plate 46, and the shape of the push plate 46 is approximately a combination of a lower circular ring at the top and a higher circular ring at the bottom but with an inner diameter smaller than the inner diameter of the top circular ring. The bottom end of the push plate 46 close to the inside is elastically connected to the outer wall of the tube body 1 through a spring 47. The shape setting of the push plate 46 ensures that there is space inside the push plate 46 to install the spring 47.

[0034] Reference Figure 2 - Figure 4 A clamping assembly 5 is provided inside the tube body 1, and the clamping assembly 5 includes a slide groove 51 and a clamping groove 52. The inner wall of the clamping groove 52 is slightly larger than the thickness of the connecting pipe. The slide groove 51 is opened on the inner wall of the tube body 1, and the clamping groove 52 is opened on the inner wall of the tube body 1 inside the slide groove 51. The inner wall of the slide groove 51 is slidably connected with a slide plate 53, and the shape of the slide plate 53 is a circular ring.

[0035] Reference Figure 2 - Figure 4 The inner wall of the slide plate 53 is provided with a mounting groove 54, and the inner wall of the mounting groove 54 is slidably connected with a clamping block 55. The cross-sectional shape of the clamping block 55 is a rectangle with a triangle cut out, and the cutting angle of the clamping block 55 is set at the end close to the spring 2 47. By setting the bevel angle, it is ensured that when the slide plate 53 moves, the clamping block 55 can enter the mounting groove 54 after the bevel angle is pushed by an external force. The end of the clamping block 55 away from the center position of the tube body 1 is elastically connected to the inner wall of the mounting groove 54 through the spring 3 56, one end of the spring 3 56 is fixedly connected to the end of the clamping block 55 away from the center position of the tube body 1, and the other end of the spring 3 56 is fixedly connected to the inner wall of the mounting groove 54. The outer wall of the tube body 1 is provided with a moving groove 57, and the outer wall of the slide plate 53 is fixedly connected with an adjusting rod 58.

[0036] Working principle: When in use, the staff first pushes the push plate 46, so that the push plate 46 moves downward and leaves the area where the control block 42 is located. At this time, the control block 42 is not affected by external force, so the control block 42 moves outward under the elastic force of the spring 43.

[0037] When the control block 42 moves outward, the space inside the air pressure chamber 41 increases, so the pressure inside the air pressure chamber 41 decreases. Therefore, at this time, the airbag 1 44 and the airbag 2 45 can shrink under the action of air pressure.

[0038] At this time, the staff keeps pushing the push plate 46 and moves the adjustment rod 58 so that the adjustment rod 58 drives the slide plate 53 to slide, so that the inclined surface of the clamping block 55 returns to the inside of the installation groove 54 under the pressure of the inner wall of the slide groove 51.

[0039] At this time, the staff will put the end of the pipe to be installed into the outside of the matching connecting pipe. Since the inner diameter of the pipe is larger than the outer diameter of the connecting pipe, the two do not fit together during the connection process, so it can be installed more easily.

[0040] After the installation is completed, the front end of the connected pipe just enters the interior of the clamping groove 52. At this time, the staff pushes the adjustment rod 58 in the opposite direction to move the clamping block 55 to an area that is in the same plane as the front end of the connected pipe. At this time, the clamping block 55 moves toward the direction close to the pipe driven by the spring three 56.

[0041] Since the clamp block 55 has the elastic force of a spring, although it cannot completely fix the pipeline, it can ensure that the pipeline is not easy to fall off during subsequent operations.

[0042] Afterwards, the staff repeats the above operation to install another pipeline. When the two pipelines are installed, the staff releases the push plate 46, so that the push plate 46 is reset under the push of the spring 2 47, so that the inner wall of the push plate 46 pushes the outer wall of the control block 42, thereby increasing the pressure inside the air pressure chamber 41, so that the airbag 1 44 and the airbag 2 45 are expanded, thereby better completing the connection of the pipelines.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
