Multifunctional trachea cannula catheter

Abstract

The invention discloses a multifunctional trachea cannula catheter which comprises a catheter body, a cuff set, a catheter inner tube and an oval piece. An oral pad is arranged at one end of the catheter body and comprises a flange portion and a tooth pad portion, a gas channel is arranged at the center of the catheter and is connected with a first oxygen tube connector, and a dosing tube, a first inflation tube, a second inflation tube, a first sputum suction tube and a second sputum suction tube are arranged on the side wall of the catheter body; a dosing opening is formed in the side wall of the catheter body and is connected with the dosing tube, the cuff set comprises a cuff I and a cuff II, the cuff I is connected with the first inflation tube, and the cuff II is connected with the second inflation tube; the oval piece is arranged at the front end of the catheter body or the catheter inner tube, one or two vent holes are formed in the oval piece, and a first sputum suction hole and a second sputum suction hole are formed in the outer side wall of the catheter body. The multi-functional trachea cannula catheter avoids the long-time compression on a local part of a tracheal mucosa wall, has a sputum suction function, prolongs the time of carrying the tube, and improves the comfort degree of tracheal intubation of a patient.

Description

technical field [0001] The invention relates to the field of medical and health technologies, in particular to a multifunctional endotracheal intubation catheter. Background technique [0002] Endotracheal intubation refers to the technique of inserting a special catheter into the trachea through the glottis. This technique can provide the best conditions for airway patency, ventilation and oxygen supply, airway suction and prevention of aspiration. At present, most of the catheters used in clinical practice are single-bag catheter body, or inner and outer double-layer cuff sleeves, which are not suitable for long-term intubation patients, and long-term intubation patients generally need to do tracheotomy to ensure the patient's ventilation, which will increase the pain of the patient , and even cause the risk of tracheal stenosis. [0003] In the course of clinical use, there are often many problems in tracheal intubation: 1) Inappropriate tube selection, causing discomfor...

Problems solved by technology

At present, most of the catheters used in clinical practice are single-bag catheter body, or inner and outer double-layer cuff sleeves, which are not suitable for long-term intubation patients, and long-term intubation patients generally need to do tracheotomy to ensure the patient's ventilation, which will increase the pain of the patient , and even the risk of tracheal stenosis

[0003] In the course of clinical use, there are often many problems in tracheal intubation: 1) Inappropriate tube selection, causing discomfort or injury to patients, and waste of tube replacement; Infection; 3) The size of the catheter lumen is fixed, and the wall of the catheter rubs against the oral cavity and tracheal mucosa as the patient moves or turns over, causing discomfort to the patient; 4) Some patients will pull out the catheter unconsciously or accidentally; 5 ) The patient has a lot of sputum, and it is difficult to discharge the sputum after catheterization; 6) Sometimes the lungs of patients need different treatment methods, such as when the left lung is relatively healthy, and when the collapse of the right lung is more serious, a small amount of oxygen can be injected into the left lung. The right lung needs more oxygen, and the existing technology rarely distinguishes the left and right lungs to achieve endotracheal intubation with different ventilation methods
