The bulk tissue, upon contacting settling funnel 707, will concentrate on the surface of settling funnel 707 and fall under gravity to the area below settling funnel 707; when the liquid level of the tissue liquid in the sedimentation tube 701 does not pass through a connecting port between the first drainage tube 701 and the sedimentation tube 701, the outer drainage tube drains the tissue clear liquid into the reservoir tube 702 and drains the tissue clear liquid into the negative pressure bag 3 through the drainage tube 2; if rising bubbles appear in the drainage process, the mother magnetic ring 802 is moved to the position where the rising bubbles are located, and magnetic particles can move along with the mother magnetic ring 802, so that the rising bubbles are broken. When a patient inhales, the pressure of a tissue liquid column or an air column flowing backwards is larger than the pressure of a thoracic cavity, the blades 1001 are forced to rotate reversely by the tissue liquid column or the air column, but the reverse stopping block can stop the reverse rotation of the gear disc 1003 through stopping the reverse rotation of the rotating rod 1004, the gear disc 1003 stops the reverse rotation of the rotating shaft 1002 again, and finally the blades 1001 are prevented from rotating reversely, so that most of the way for the tissue liquid column or the air column to flow backwards is blocked.
The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts of the present invention. The foregoing is only a preferred embodiment of the present invention, and it should be noted that there are objectively infinite specific structures due to the limited character expressions, and it will be apparent to those skilled in the art that a plurality of modifications, decorations or changes may be made without departing from the principle of the present invention, and the technical features described above may be combined in a suitable manner; such modifications, variations, combinations, or adaptations of the invention using its spirit and scope, as defined by the claims, may be directed to other uses and embodiments.
