Polyvinyl chloride material for tracheal intubation and preparation method thereof

Abstract

The invention relates to a polyvinyl chloride material for tracheal intubation. The polyvinyl chloride material is prepared from the following components in parts by weight: 90-110 parts of polyvinyl chloride resin, 0.2-10 parts of an antibacterial agent, 40-60 parts of a plasticizer and 1-20 parts of a stabilizer. The polyvinyl chloride material disclosed by the invention is excellent in antibacterial effect and small in irritating property, can achieve the effects of effectively preventing the risk of infection, sputum scab blockage and injuries in the tracheal intubation retention process and reducing complications, is conveniently used by medical personnel and has high safety performance.

Description

technical field [0001] The invention belongs to the technical field of medical material preparation, and in particular relates to a polyvinyl chloride material for tracheal intubation and a preparation method thereof. Background technique [0002] Endotracheal intubation is a medical device that needs to be used for effective mechanical ventilation during the rescue of patients under general anesthesia and many critically ill patients. Although endotracheal intubation solves the difficulty of ventilation and facilitates the suction of foreign bodies such as sputum and blood in the airway, the endotracheal intubation catheter currently used in clinical practice is mainly made of medical polyethylene plastic, and the catheter has adhesion to airway secretions. After intubation, the airway mucosa will be compressed, rubbed, irritated, etc., which will easily cause intubation complications, resulting in the failure of catheter indwelling and extubation; complications are inevita...

AI Technical Summary

Problems solved by technology

Although endotracheal intubation solves the difficulty of ventilation and facilitates the suction of foreign bodies such as sputum and blood in the airway, the endotracheal intubation catheter currently used in clinical practice is mainly made of medical polyethylene plastic, and the catheter has adhesion to airway secretions. After intubation, the airway mucosa will be compressed, rubbed, irritated, etc., which will easily cause intubation complications, resulting in the failure of catheter indwelling and extubation; complications are inevitable in patients with endotracheal intubation, and directly affect the endotracheal intubation. Once it happens, the medical staff have to take extubation, re-intubate the trachea or place a tracheotomy to place the tracheal tube, which increases the medical economic burden, treatment risk and physical and mental torture of the patient.
