Detailed Description

The cleaner for the respiratory department comprises a cannula 1, a main suction tube 2 penetrating through the cannula 1 and a cleaner main body arranged at the inner end of the main suction tube 2, wherein the cannula 1 penetrates into a patient's trachea to perform operation, the main suction tube 2 is used for sucking and discharging sputum from the cleaner main body, that is, the outer end of the main suction tube 2 is communicated with an aspirator. The cleaner main body enters the affected part through the cannula 1, and eliminates phlegm and cleans the affected part. The materials of the components are all medical grade materials, so that sterility and safety are ensured.

Referring to fig. 1 and 2, the cleaner body includes a distal suction tube 3 and a mounting frame 4, the mounting frame 4 is square, the upper end of the distal suction tube 3 passes through a central hole on the bottom plate of the mounting frame 4 and stretches into the mounting frame 4 to form a rotation fit relationship, and the upper end of the distal suction tube 3 is communicated with the main suction tube 2 through a rotary joint 5, thereby preventing the distal suction tube 3 from driving the main suction tube 2 to rotate in the process of rotation.

The peripheral surface overcoat that terminal suction tube 3 is located the terminal one section of intubate 1 is equipped with the stable subassembly that is used for setting up terminal suction tube 3 stable at the intubate 1 center, because terminal suction tube 3 has certain length, and its rigidity is usually unsuitable too big, stable subassembly's main role lies in carrying out certain support to terminal suction tube 3, prevents that it from appearing too big lateral oscillation at pivoted in-process. The stabilizing assembly has more specific structures, for example, the stabilizing assembly can be an air bag arranged on the inner wall of the cannula 1, and after the cleaner main body is worn in place, the air bag is inflated to support the cleaner main body, but the stabilizing assembly can also be a supporting air bag 15 fixedly sleeved outside the tail end suction tube 3, the supporting air bag 15 is communicated with the air inflation tube 8, so that the supporting air bag 15 and the inflation of the air bag cleaning head air bag body can be realized through one air inflation tube 8, the overall structure of the cleaning head air bag cleaning device is more compact, and under the condition, the supporting air bag 15 and the cannula 1 also form running fit substantially, and the cleaning head air bag cleaning device can also play a role in preventing the tail end suction tube 3 from rotating too fast due to a certain friction force between the outer side wall of the supporting air bag 15 and the inner wall of the cannula 1.

The rotary driving assembly for driving the tail end suction tube 3 to rotate is arranged on the peripheral surface of the tail end suction tube 3 positioned below the rotary joint 5 in the mounting frame 4. The main function of the driving component is to drive the tail end suction tube 3 to rotate, and the specific structure of the driving component is more, for example: can be a micro motor which is meshed with a driving gear on the side wall of the tail end suction tube 3 to realize torsion transmission. However, this method requires a single-chip microcomputer, a motor, a driving gear, a power supply, etc. for controlling the motor to be implanted in the present invention, and the structure is relatively complex.

Therefore, the invention also provides a driving assembly with simple structure, which has the characteristics of simple operation, low cost and the like, and specifically: as shown in fig. 2, the rotary drive assembly includes a drive wheel 11, a pull wire 12 and a reset element 13.

And a storage area is formed between the two disc bodies, the pull wire 12 is wound in the storage area, the inner end of the pull wire 12 is fixedly connected with the driving wheel 11, and the outer end sequentially passes through the guide part and the wire hole at the top of the mounting frame 4 and then extends to the outside along the insertion tube 1 to be connected with the pull ring. The reset part 13 is a clockwork spring, and the tail end suction tube 3 is connected with the mounting frame 4 through the clockwork spring. When the pull ring is pulled by an operator, the pull ring drives the pull wire 12, the pull wire 12 can drive the driving wheel 11 to rotate, and then the tail end suction tube 3 is driven to rotate, the storage area between the two disc bodies is used for storing the winding part of the pull wire 12, the width of the storage area is preferably matched with the size of the pull wire 12, so that winding is more regular, winding and unwinding smoothness is better, and on the basis, a horn-shaped guide opening is preferably arranged between the edges of the two disc bodies forming the driving wheel 11, so that the pull wire 12 can enter the storage area more accurately. The guiding component may be a guiding ring set, or as shown in fig. 2, is a guiding block 14 arranged on the inner side wall of the mounting frame 4, a guiding hole is arranged in the guiding block 14, and the pull wire 12 is arranged in the guiding hole in a penetrating way.

As shown in fig. 1, the lower end of the distal suction tube 3 is provided with an air bag type cleaning head for cleaning sputum on the inner surface of the trachea, which scrapes the sputum off the inner wall of the trachea by rotating, and simultaneously has the function of sucking the sputum. The air bag type cleaning head comprises an air bag body 6 which is matched with the inner diameter of an air pipe, the air bag body 6 is fixedly arranged at the lower end of the tail end suction pipe 3 through a connector 7, the air bag body 6 is communicated with the inner end of an air inflation pipe 8, the air inflation pipe 8 sequentially penetrates through the tail end suction pipe 3, the rotary connector 5 and the main suction pipe 2 to extend to the outside, and the air inflation pipe 8 is used for inflating.
