Suction self-adaptive device of suction apparatus

Abstract

The invention discloses a suction self-adaptive device of a suction apparatus. The suction force self-adaption device comprises a suction head connected with a suction apparatus body through a guide pipe, the bottom of the suction head is connected with a plurality of one-way valve plates in an opening and closing mode, the bottom of each one-way valve plate is provided with an arc-shaped protrusion, the cross section of each one-way valve plate is in a fan shape, and a suction hole bent to be in an L shape is formed in each one-way valve plate. An arc-shaped blocking cover for sealing the through hole is arranged at one end of the suction hole, an equipment plate is further arranged in the suction head, a plurality of micro sensors are arranged on the equipment plate, a contact is arranged at the top of the one-way valve plate, the micro sensors are electrically connected with a controller in the aspirator main body, and a vacuum pump of the aspirator main body is also electrically connected with the controller. The suction force self-adaption function of the suction apparatus is achieved, and medical negligence caused by lack of experience or misoperation of operators can be effectively avoided.

Description

technical field [0001] The invention relates to a self-adaptive suction device of a suction device. Background technique [0002] The suction device is used to suck out bleeding, exudate, pus or turbid tissue fluid on the surface of thoracic viscera during the operation, so as to make the operation clear and reduce the chance of contamination. The principle of the suction device is very simple. It is to create the negative pressure state of its suction head by a certain method, so that the atmospheric pressure will squeeze the material outside the suction head to the suction head, thereby completing the effect of "suction". Blood or effusion, sputum suction in clinical first aid, etc., are inseparable from the aspirator. [0003] And the suction device in the prior art is because of its strong suction, so special attention should be paid to the control of the suction during the operation, which requires the operator to have quite rich experience; On internal organs or bloo...
