Sputum suction and medicine injection type trachea cannula

Abstract

The invention belongs to the technical field of surgical medical equipment, and particularly relates to a sputum suction and medicine injection type trachea cannula which comprises a main tube body, a sputum suction tube, a probe device, a medicine injection tube and a main inflation tube. The top of the main tube body is connected with a respirator connector, a tube foot is arranged at the bottom of the main tube body, and a protective layer is arranged on the outer wall of the tube foot. The protective layer is a mixture of gelatin and starch, a main air bag is arranged below the outer wall of the main tube body and the main inflation tube is arranged on the right side of the main tube body. A first silica gel backflow prevention gasket is installed on the inner wall of a medicine injection opening, medicine is injected into the medicine injection tube, pressure is applied to the medicine injection tube, and the pressure in the medicine injection tube is larger than the pressure outside the medicine injection opening, When the first silica gel backflow prevention gasket is opened, medicine enters the trachea from the medicine injection opening, and pressurization in the medicine injection tube is stopped after medicine injection is finished; when the first silica gel backflow prevention gasket is closed, the medicine cannot enter the medicine injection tube from the medicine injection opening, so that the effective anti-backflow effect is achieved, and the medicine injection tube is prevented from being polluted by the backflow medicine.

Description

technical field [0001] The invention relates to the technical field of surgical medical equipment, in particular to a tracheal intubation tube for suctioning and injecting medicine. Background technique [0002] Endotracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis, which is called endotracheal intubation. This technique can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory tract suction and prevention of aspiration. , in the process of use, it is necessary to inject medicine through the endotracheal tube. With the development of science and technology, people have researched and invented endotracheal intubation that can inject medicine. It does not have the anti-reflux function. When injecting medicine, the medicine will flow back into the injection tube through the injection port. When sucking sputum, the sputum will flow back from the suction tube into the trac...
