Special negative pressure drainage device for thyroid surgery

Abstract

The invention belongs to the technical field of thyroid treatment, and particularly relates to a special negative pressure drainage device for thyroid surgery, which comprises a first drainage tube, a second drainage tube and negative pressure equipment, the outer wall of the first drainage tube is connected with the outer wall of the second drainage tube, the bottom of the first drainage tube and the bottom of the second drainage tube are provided with openings, and a first silica gel backflow prevention sheet is arranged in each opening. The top of the first drainage tube and the top of the second drainage tube are communicated with an inner cavity of the first transverse tube. During use, seepage in the body of a patient can be rapidly extracted through the first drainage tube and the second drainage tube, and due to the fact that the left side and the right side of the first transverse tube are connected with negative pressure equipment through liquid outlet tubes, when one drainage tube is blocked, the negative pressure equipment can be rapidly extracted; when the drainage tube is blocked, the pressure intensity in the blocked drainage tube changes, at the moment, the second silica gel backflow prevention piece is opened, suction force in the two liquid outlet tubes is concentrated in the unblocked drainage tube, the drainage speed is increased in a self-adaption mode, and the situation that the drainage speed is low, and seepage in the body of the patient cannot be extracted in time is avoided.

Description

technical field [0001] The invention relates to the technical field of thyroid therapy, in particular to a special negative pressure drainage device for thyroid surgery. Background technique [0002] The thyroid gland is located in a closed space in the deep fascia of the neck, and the tissue blood supply is very rich; thyroid diseases are mainly open surgery, and thyroid surgery is used to treat thyroid nodules, thyroid adenomas, primary or secondary hyperthyroidism , thyroid tumor, etc.; due to the large wound surface separated during thyroid surgery, there will be a certain amount of exudate after surgery. Therefore, a drainage device should be placed after thyroid surgery. When the existing drainage device is in use, drainage is often performed through a drainage tube and a negative pressure device, and a plurality of drainage holes are opened on the drainage tube to improve drainage efficiency. The speed becomes slow, and the exudate from the patient's body cannot be ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a special negative pressure drainage device for thyroid surgery, so as to solve the problem that the drainage speed is slowed down and the exudate in the patient's body cannot be extracted in a timely manner.
