[0026] Embodiment 1

[0027] In combination Figure 1 And Figure 2 As shown in the drawings, the embodiment provides a splash-proof gas pipe intubation conversion joint, which comprises an upper joint 1, a lower joint 2 and a rotary limiting piece 4, the upper joint 1 and the lower joint 2 can be connected in an integral molding manner, the upper joint 1 is internally provided with a first through hole, the lower joint 2 is internally provided with a second through hole, and the first through hole and the second through hole are communicated; specifically, the lower joint 2 is connected with a pipeline leading into the lung, and the upper joint 1 is connected with a device for injection or a pipeline for injection. Wherein, the upper joint 1 and the lower joint 2 are both soft materials.

[0028] In the embodiment, the upper joint 1 is internally provided with a shielding plate 3, and the outer diameter of the upper joint 1 gradually increases from top to bottom. The shielding plate 3 is installed at a distance upwards from the position where the upper joint 1 and the lower joint 2 are connected, for example, the distance is set to 1-3 cm. Specifically, the shielding plate 3 can be triangular, and two sharp ends of the triangular are respectively connected with the inside of the upper joint 1, and the other sharp end is externally provided with a scale mark at the corresponding position. Further, the shielding plate 3 is provided with two plates, which are symmetrically arranged on both sides of the central axis of the upper joint 1. At the same time, the outer movable sleeve of the upper joint 1 is provided with a rotation limiting piece 4, and further, the rotation limiting piece 4 can move up and down on the upper joint 1.

[0029] In the embodiment, the rotation limiting piece 4 is internally provided with a through hole structure, which can be sleeved on the outside of the upper joint 1. Specifically, the rotation limiting piece 4 includes an upper limiting rod 5 and a lower limiting rod 6, and the upper limiting rod 5 and the lower limiting rod 6 are both internally provided with a through hole, and the through holes of the two are consistent in size, and the upper joint 1 is stably sleeved through the two through holes. One side surface between the upper limiting rod 5 and the lower limiting rod 6 is provided with a convex part 7, which is convenient for the operator to hold and operate. In order to further improve the stability of the connection between the upper limiting rod 5 and the lower limiting rod 6, the other side surface between the upper limiting rod 5 and the lower limiting rod 6 is provided with a connecting rod 8, which can connect the upper limiting rod 5 and the lower limiting rod 6, and the connection mode can be fixed connection or detachable connection. It should be noted that one end of the connecting rod 8 is fixed to the upper limiting rod 5 or the lower limiting rod 6, and the other end of the connecting rod 8 is detachably connected to the lower limiting rod 6 or the upper limiting rod 5. For the detachable connection mode, a conventional mode such as buckle fastening can be selected to realize it, which will not be described in detail here.

[0030] In the embodiment, when injecting the medicine, the rotation limiting piece 4 is located at the initial position (i.e. the upper end part of the upper joint 1), at this time, the through hole at the connection between the upper joint 1 and the lower joint 2 is the largest, when stopping injecting the medicine, the rotation limiting piece 4 is rotated downwards to the scale mark position. At this time, due to the inward extrusion force of the rotation limiting piece 4, the two shielding plates 3 move towards the direction of the central axis of the upper joint 1, and thus the through hole at the connection between the upper joint 1 and the lower joint 2 becomes smaller, and the infant exhales outwardly, and due to the smaller through hole between the two shielding plates 3, part of the exhaled medicine is shielded by the shielding plate 3, reducing the occurrence of splashing. That is, the size of H in Figure 1 and Figure 2 changes.

[0031] It should be noted that when the injection of the medicine is continued, the rotation limiting member 4 can be rotated reversely to move away from the position of the scale mark, or the rotation limiting member 4 can not be rotated. This is because, since the two shielding plates 3 have the non-closed through hole, only the through hole is smaller, and the injection of the medicine is not hindered from flowing from the upper joint 1 to the lower joint 2, only the flow is reduced, so the medicine can be directly injected without rotating the rotation limiting member 4.

[0032] The above is only the embodiment of the present application, which is described in detail, but it should not be understood as a limitation on the scope of the present application. It should be noted that for those skilled in the art, without departing from the concept of the present application, some modifications and improvements can be made, which are all within the scope of the present application.
