Modular tracheal intubation catheter of breathing machine

Abstract

The invention relates to the technical field of medical tracheal intubation catheters, and discloses a modular tracheal intubation catheter of a breathing machine. The modular tracheal intubation catheter comprises a tracheal intubation catheter, a subglottic flushing tube, a catheter air pipe, a controller, a pressure sensor and a pressure monitor, wherein a catheter air bag is arranged at one end of the tracheal intubation catheter, and a breathing machine connector is arranged at the other end of the tracheal intubation catheter; one end of the catheter air pipe is connected with the catheter air bag, and the other end of the catheter air pipe is connected with the pressure monitor and a first electromagnetic valve; an air inflation device is connected with the first electromagnetic valve; the pressure sensor is arranged in the catheter air bag and is in communication connection with the pressure monitor; one end of the subglottic flushing tube is connected with the tracheal intubation catheter, and the other end of the subglottic flushing tube is connected with a negative-pressure suction device through a second electromagnetic valve; the controller is in communication connection with the first electromagnetic valve, the second electromagnetic valve and the pressure monitor separately. Through the setting of the controller, the modular tracheal intubation catheter has the functions of automatically managing the air bag and conducting flushing, effectiveness during mechanical ventilation of a patient after insertion of the tracheal intubation catheter can be guaranteed,and meanwhile, the occurrence rate of VAP is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical endotracheal intubation catheters, in particular to a ventilator modular endotracheal intubation catheter. Background technique [0002] The structure of the endotracheal intubation catheter currently used in the hospital is composed of an endotracheal catheter, a ventilator interface, an air bag, and an air bag inflation tube. Under the guidance of anesthesia laryngoscope, the endotracheal intubation tube is inserted into the patient's trachea. The air bag is inflated, the ventilator interface is connected to the ventilator to perform mechanical ventilation for the patient, and assist the patient to breathe. [0003] But there are following defects in existing tracheal tube: [0004] 1. During the use of the airbag, the airbag may be deflated due to staying in the throat for a long time, causing a gap in the fit between the airbag and the throat, resulting in air leakage from the ventilator to ...

AI Technical Summary

Problems solved by technology

The use of a subglottic suction endotracheal tube for timing or continuous suction of the secretion can reduce the incidence of VAP. The endotracheal tube that can attract secretions between the subglottis and the air bag is used in clinical practice. However, patients with endotracheal intubation tubes are extremely prone to A large amount of oral secretions, the above secretions can continuously move down to the subglottis or even the lower respiratory tract, which can easily lead to the occurrence of VAP
