Therefore, one connecting device is used, the tracheal cannula can be selectively connected with two inputs, namely, the first branch pipe 2 or the second branch pipe 3 can be used for communicating with the feeding equipment, and the other branch pipe is used for communicating with the equipment for humidification or anesthesia, and the aim of one pipe with multiple purposes is fulfilled.

Even if first branch pipe 2 and second branch pipe 3 have communicated different supply apparatus, through the removal of inner tube 4 in connecting pipe 1, that is at the in-process that inner tube 4 rotated, inner tube 4 moved along the axis of connecting pipe 1 to in-process that inner tube 4 removed can be with the intercommunication mouth of first branch pipe 2 and connecting pipe 1 and/or the intercommunication mouth shutoff of second branch pipe 3 and connecting pipe 1 promptly. Meanwhile, in the process of moving the inner pipe 4, the communication port between the first branch pipe 2 and the connecting pipe 1 and the communication port between the second branch pipe 3 and the connecting pipe 1 can be selectively opened or simultaneously opened.

Even if the operation of replacing the adsorbate is very convenient, when the adsorbate such as medical cotton needs to be replaced, the adsorbate filled in the inner tube 4 can be removed and replaced by only taking out the rotating head 5 and pulling the tongue plate 6 from between the inner tube 4 and the inner wall of the connecting tube 1.

The scheme is further explained;

referring to fig. 5, 6 and 7, the first end of the connection tube 1 is used for connecting a trachea cannula, the gas transmission end of the trachea cannula is directly inserted into the first end of the connection tube 1, the inner diameter of the first end is the same as the outer diameter of the trachea cannula, so that the inner wall of the first end is used for pressing the outer wall of the trachea cannula,

meanwhile, the rotating head 5 is also arranged at the second end of the connecting pipe 1, the axis of the first branch pipe 2 is perpendicular to the axis of the connecting pipe 1, the axis of the second branch pipe 3 is inclined to the axis of the connecting pipe 1, the inclined second branch pipe 3 is arranged to be convenient for medical staff to mark, and the inclined second branch pipe 3 and the first branch pipe 2 perpendicular to the axis of the connecting pipe 1 can be easily distinguished.

Referring to fig. 8, 9, 10 and 11, a blocking block 7 is installed on the inner wall of the inner tube 4 for placing absorbent such as medical cotton and sponge, and a plurality of vent channels 8 penetrating along the axis of the inner tube 4 are formed in the blocking block 7, so as to prevent the blocking block 7 from completely blocking the inner tube 4.

Meanwhile, the wall thickness of the smooth surface of the inner tube 4 is smaller than that of the outer thread surface of the inner tube 4, and an embedding cavity 9 for embedding the tongue plate 6 is arranged between the smooth surface of the inner tube 4 and the inner wall of the connecting tube 1.

It is explained here that the wall thickness of the smooth surface is uniform, the wall thickness of the inner tube 4 provided with the externally threaded surface is uniform, and the inner wall of the smooth surface and the inner wall provided with the external thread surface form a complete arc surface, namely, a step structure with poor pipe wall is formed at the junction of the pipe wall provided with the external thread cotton and the pipe wall of the smooth surface, the step structure and the outer wall of the smooth surface form an assembling groove, meanwhile, after the inner tube 4 is arranged in the connecting tube 1, the inlaid cavity 9 can be formed between the whole of the arranging groove and the inner wall of the connecting tube 1, wherein the inlaid cavity 9 is used for arranging the tongue plate 6, and the two ends of the tongue plate 6 are respectively contacted with the step structures at the two ends in the rotating process of the tongue plate 6, thus, in the process of rotating the tongue plate 6, the two ends of the tongue plate 6 are utilized to push the step structure, so that the tongue plate 6 drives the inner tube 4.

Then, referring to fig. 12, 13 and 14, the rotating head 5 includes a positioning plate 51, an embedding groove 52 is formed in a bottom surface of the positioning plate 51, an inner diameter of the embedding groove 52 is the same as an outer diameter of the connecting pipe 1, so that the rotating head 5 can be fastened to the connecting pipe 1, specifically, the connecting pipe 1 is directly installed in the embedding groove 52, the tongue plate 6 is installed in the embedding groove 52, and a holding block 53 is installed on a top surface of the positioning plate 51, that is, the positioning plate 51 can be driven to rotate by twisting the holding block 53.

On the basis, the tongue plate 6 is an arc-shaped plate, the tongue plate 6 and the connecting pipe 1 are coaxially arranged, and the radian of the tongue plate 6 is the same as that of the pipe wall of the connecting pipe 1.

Then, the distance between the extrados of the tongue plate 6 and the inner wall of the embedding groove 52 is the same as the thickness of the tube wall of the connecting tube 1, that is, part of the tube wall of the connecting tube 1 can be directly clamped between the tongue plate 6 and the inner wall of the embedding groove 52, so that the connecting tube 1 and the rotating head 5 can be more stably installed, the rotating head 5 and the connecting tube 1 are more difficult to separate along the axial direction, and although the problem of relatively tight rotation is brought, the installation stability is more important compared with the convenience of rotation.

The thickness of the tongue plate 6 is the same as the distance from the smooth surface of the inner tube 4 to the inner wall of the connecting tube 1.

Of course, on the basis of the technical scheme, a more optimized scheme is provided,

specifically, referring to fig. 15, 16 and 17 again, a clamping device is installed at an end of the connecting tube 1 opposite to the rotating head 5, the clamping device is specially used for clamping the air inlet end of the endotracheal tube, so that the endotracheal tube and the connecting tube 1 are fixed more stably,

specifically, the clamping device comprises an elastic clamping piece 10 which surrounds the axis of the connecting pipe 1 and is arranged at the end part of the pipe wall of the connecting pipe 1, the elastic clamping piece 10 surrounds to form a clamping part, the outer wall of the clamping part is provided with an external thread, the head end of the external thread arranged on the clamping part extends upwards and extends to the outer wall of the connecting pipe 1, the inner diameter of the clamping part is smaller than the outer diameter of the tracheal cannula to be clamped, so that the elastic clamping piece 10 can be extruded and deformed after the air inlet end of the tracheal cannula is inserted, namely the elastic clamping piece 10 has resilience, a fastening ring 11 is arranged on the external thread of the clamping part, the inner wall of the fastening ring 11 is provided with an internal thread, and in a normal state, the fastening ring 11 is arranged on the external thread extending to the outer wall of the connecting pipe 1, so that the air inlet end of the tracheal cannula can be smoothly arranged in the connecting pipe 1 when the tracheal cannula is arranged with the connecting pipe 1, then, after the installation is completed, the fastening ring 11 is rotated to move the fastening ring 11 downward, so that the elastic clamping pieces 10 are pressed by the fastening ring 11, and the air inlet end of the endotracheal tube is clamped by the elastic clamping pieces 10.

Furthermore, the bottom of elasticity clamping piece 10 orientation clamp splice 12 is installed to the one side in the clamping part, clamp splice 12 orientation the one side in the clamping part sets up to the arcwall face.

That is, the air inlet end of the tracheal cannula can enter the clamping part more easily by utilizing the arc-shaped surface.

A further optimization scheme is optimized for the tongue plate 6, and the purpose of the optimization scheme is to avoid the situation that the tongue plate 6 blocks a communication port of the first branch pipe 2 or the second branch pipe 3 when the first branch pipe 2 or the second branch pipe 3 needs to be communicated.

Specifically, as shown in fig. 18, fig. 19, and fig. 20, that is, in a normal state, a through communication channel 13 is provided on the tongue plate 6, the communication channel 13 extends upward and penetrates through the rotation head 5, a baffle 14 having the same radian as the tongue plate 6 is installed in the communication channel 13, the baffle 14 completely fills the communication channel 13, the thickness of the baffle 14 is the same as the thickness of the communication channel 13 penetrating through the rotation head 5, the thickness of the baffle 14 is smaller than the thickness of the tongue plate 6, and the top end of the baffle 14 extends upward and extends out of the top surface of the rotation head 5.

Thus, in the using process, if the tongue plate 6 blocks the communication port between the first branch pipe 2 or the second branch pipe 3 and the connecting pipe 1, the baffle plate 14 is only required to be lifted upwards, and the baffle plate 14 is moved into the rotating head 5 or above the communication port, so that the communication channel 13 is opened, and the communication port is communicated.

The opened state of the shutter 14 described above can be referred to specifically as the state shown in fig. 21.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
