Tracheal catheter capable of rebuilding cough peak flow velocity

Abstract

The invention discloses a tracheal catheter capable of rebuilding a cough peak flow velocity, relates to the technical field of medical apparatus and instruments, and aims to solve the problem in theprior art that subglottic secretion cannot be effectively cleared away during retention of the tracheal catheter. The tracheal catheter capable of rebuilding the cough peak flow velocity comprises a tracheal catheter body, an external balloon, a balloon catheter, an internal balloon, an inflation inlet, an inflation catheter, an air outlet port, a sealing cavity and air outlet holes; the trachealcatheter body comprises three independent cavities; the inflation inlet is communicated with the air outlet port through the inflation catheter; and the sealing cavity comprises the air outlet port inthe inner wall and the three air outlet holes in the outer wall, and annularly winds the outer wall of the tracheal catheter body. The tracheal catheter capable of rebuilding the cough peak flow velocity has the advantages that airflow with a certain velocity can be generated in the three air outlet holes by giving airflow with a certain velocity in the inflation inlet, the cough airflow velocityunder a normal person's physiological status is achieved through regulation, and the strong airflow impact force impacts the subglottic secretion out of the aditus glottidis to achieve the purpose ofrebuilding effective cough reflex of the human body.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an endotracheal tube capable of reconstructing cough peak flow rate. Background technique [0002] Endotracheal intubation refers to the insertion of a special endotracheal tube through the mouth or nose into the patient's trachea. It is a technique for intratracheal anesthesia and rescue of patients, and it is also the most effective means to keep the upper airway open. Endotracheal or endobronchial intubation is a safety measure for non-spontaneously breathing patients to maintain lung ventilation through a ventilator through a tracheal tube. [0003] However, clinically common endotracheal intubation cannot remove the retention on the air bag, and indwelling an endotracheal tube with subglottic suction function to remove the retention on the air bag requires not only pre-preparation and successful indwelling of a special endotracheal tube, but also many clinical complications ...
