Problems solved by technology

At present, most of the medical aspirators adopt the negative pressure suction method, which is fast and convenient, but in the process of suction, the suction head is easy to be blocked. Remove the negative pressure tube and then connect the positive pressure tube, use positive pressure to perform reverse flushing, and some complicated suction heads need to be disassembled and cleaned
During surgery or other medical procedures, if continuous suction is required, the positive pressure tube and the negative pressure tube must be repeatedly exchanged and connected when the suction head is blocked, resulting in troublesome operation and technical problems that affect the treatment effect

Abstract

The invention in particular relates to an aspirator used in medical treatment, aims at solving the technical problems of a medical aspirator in the prior art and provides a medical aspirator. The medical aspirator comprises a suction head, a hard outer pipe body, an inner pipe body and a driving device connected with the bottom end of the inner pipe body, wherein a positive pressure joint and a negative pressure joint are respectively arranged on the pipe wall close to the top of the outer pipe body; the inner pipe body which can slide up and down is arranged in the pipe cavity of the outer pipe body, the bottom end of the inner pipe body is closed, the top end of the inner pipe body is in through connection with the suction head, an open slot is formed in the pipe wall of the inner pipe body, when the inner pipe body slides up and down in the outer pipe body, the open slot can run through the positive pressure joint and the negative pressure joint in a time division manner; and the driving device can drive the inner pipe body to move up and down in the outer pipe body. The medical aspirator is reasonable in structure and easy to operate and can be widely applied to aspiration operation in the medical treatment.

Description

technical field [0001] In particular, the invention relates to a suction device for medical use. Background technique [0002] Aspirators are widely used in medical treatment, such as suctioning sputum and removing tissue fluid during surgery. At present, most of the medical aspirators adopt the negative pressure suction method, which is fast and convenient, but in the process of suction, the suction head is easy to be blocked. The negative pressure tube is removed and then connected to the positive pressure tube, and the positive pressure is used for reverse flushing, and some complicated suction heads need to be disassembled and cleaned. During surgery or other medical procedures, if continuous suction is required, the positive pressure tube and the negative pressure tube need to be repeatedly exchanged and inserted after the suction head is blocked, which causes troublesome operation and technical problems affecting the therapeutic effect.
