The locking pin 42 of the locking mechanism is first pulled back and retained by the retaining pin 44. When the negative pressure bottle 6 is lifted up, the suction cup 40 is taken up by the negative pressure bottle 6, the screw rod 41 is pulled by the suction cup 40 to move upwards, the turntable 31 rotates to wind each connecting pipe on the pipe winding assembly 30, meanwhile, the lower end of the screw rod 41 drives the pull rod 35 to move upwards, the pull rod 35 is pushed by the connecting rod 33 to deflect and extrude each connecting pipe in the direction away from the pull rod 35, and therefore the connecting pipes are wound on the pipe winding assembly 30 in a neat and tight mode. After the negative pressure bottle 6 is lifted to a certain height, the suction cup 40 is separated from the negative pressure bottle 6, and the second connection pipe is kept fixed around the pipe assembly 30 under the action of the contraction spring 36.
Example 3
This embodiment is further improved on the basis of embodiment 1, and the difference between this embodiment and embodiment 1 is that in this embodiment, the clamping force of the pipe winding assembly 30 can be adjusted as required.
The inventor finds that when the sputum suction operation is performed, part of the second connecting pipe 5 is wound on the winding pipe assembly 30, the push rod 32 presses the second connecting pipe 5 under the action of the contraction spring 36, and the second connecting pipe 5 wound on the winding pipe assembly 30 is flattened, so that the overall drift diameter of the section of the second connecting pipe 5 is reduced. When sputum suction is performed, the overall drift diameter of the second connecting pipe 5 can be adaptively adjusted according to the physical signs of patients, and if the concentration of sputum is high, the clamping force can be increased to suck sputum at a slow speed; and the concentration of sputum then can reduce the clamp force when less, and the latus rectum of second connecting pipe 5 increases relatively, inhales phlegm with faster speed.
Specifically, in the pipe winding assembly 30 of the present embodiment, the pull rod 35 includes a first connecting portion 351, a second connecting portion 352 and an adjusting screw 353, the upper end of the first connecting portion 351 is connected to the retraction spring 36, and the lower end is slidably connected to the second connecting portion 352; the adjustment screw 353 passes through the second connection portion 352 and is screw-connected with the first connection portion 351. Each link 33 is pin-connected to the second connection portion 353. When the clamping force needs to be increased, the adjustment screw 353 may be rotated to decrease the distance between the first connection part 351 and the second connection part 352; when it is required to reduce the clamping force, the adjustment screw 353 may be rotated reversely to increase the distance between the first and second connection parts 351 and 352. Under the action of the contracting spring 36, the clamping force is adjusted not rigidly but elastically, so as to avoid the second connecting pipe 5 from being blocked due to the rapid extrusion.
The technical scheme of this embodiment reduces for the local cross-section to second connecting pipe 351, can avoid sputum or scab body to block up the pipeline. In the solution of this embodiment, if a portion of the scab body with a larger volume is encountered, the retraction spring 36 can be deformed adaptively to allow it to pass through the second connection pipe 5.
The apparatus of the present application has been described in detail with reference to the preferred embodiments thereof, however, it should be noted that those skilled in the art can make modifications, alterations and adaptations based on the above disclosure without departing from the spirit of the present application. The present application includes the specific embodiments described above and any equivalents thereof.
