Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

Examples

Referring to fig. 1, an endotracheal tube includes: the disk 10 is mounted. One side of the mounting disc 10 is connected with a guide pipe 20, the other side of the mounting disc is provided with a mounting surface 11, the middle part of the mounting disc 10 is provided with a vent hole 12, the guide pipe 20 is arranged around the vent hole 12, so that the vent hole 12 is communicated with the guide pipe 20, and two ends of the mounting disc 10 are respectively provided with a hanging hole 17. The mounting surface 11 is provided with a baffle 13, a first stopper 15 and a second stopper 16. The bottom surface of the baffle 13 is in contact with the mounting surface 11 and is connected to the mounting plate 10 via the rotary shaft 14, and the ventilation holes 12 can be half-blocked or full-blocked by rotating the baffle 13. In this embodiment, a rubber sleeve is provided at the joint between the rotating shaft 14 and the baffle 13, so that the rotation of the baffle 13 is damped.

Referring to fig. 2 to 4, the baffle 13 is in a fan shape and includes a straight side 131 and an arc side 132. The baffle 13 is close to the vent hole 12, and the straight side 131 faces the vent hole 12. The rotating shaft 14 is close to the middle of the straight side face, and when the baffle 13 rotates around the rotating shaft 14, the baffle 13 rotates eccentrically, so that the vent hole 12 can be gradually shielded, and half blocking or full blocking is realized. The stopper 133 is provided on the top surface of one end of the shutter 13, i.e., the top surface of one end of the straight side 131. The top of the baffle 13 is provided with a toggle block 134 for toggling the baffle 13.

The first limiting member 15 and the rotating shaft 14 are respectively located at two corresponding sides of the ventilation hole 12, that is, the first limiting member 15 and the rotating shaft 14 are oppositely disposed with respect to the ventilation hole 12. The second limiting members 16 and the stoppers 133 are respectively located at two corresponding sides of the vent holes 12, and the second limiting members 16 are close to the end of the baffle 13, that is, the stoppers 133 are located at one end of the baffle 13, and the second limiting members 16 are close to the other end of the baffle 13.

The first limiting member 15 and the second limiting member 16 have the same structure and both include a connecting block 151 and a limiting block 152. The bottom end of the connection block 151 is connected to the mounting surface 11. One end of the limiting block 152 is connected with the top end of the connecting block 151, and the other end of the limiting block 152 faces the vent hole 12, so that a gap is formed between the limiting block 152 and the mounting surface 11. The distance between the stopper 152 and the mounting surface is larger than the thickness of the shutter 13, and when the shutter 13 rotates, the stopper 152 does not contact the shutter 13 but only contacts the stopper 133. The stopper 133 can rotate from two directions to be in contact with the stoppers 152 on the first stopper 15 and the second stopper 16, respectively, so as to perform half-blocking or full-blocking.

Referring to fig. 5 and 6, the trial occlusion (half occlusion) process of the endotracheal tube: the hand-held toggle block 134 rotates the baffle 13 to make the stopper 133 contact with the stopper 152 on the first stopper 15, and at this time, the baffle 13 blocks half of the space of the vent hole 12, thereby completing the trial blocking operation.

The full-blocking process of the tracheal catheter comprises the following steps: the hand-held toggle block 134 rotates the baffle 13 in the opposite direction, and the baffle 13 passes through the space between the limiting block 152 on the second limiting member 16 and the mounting surface 11 until the stop block 133 contacts the limiting block 152 on the second limiting member 15, at this time, the baffle 13 blocks all the space of the vent hole 12, and the full-blocking operation is completed.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
