Continuous controlled-release drug delivery tracheal catheter

Abstract

The invention discloses a continuous controlled-release drug delivery tracheal catheter which comprises a tracheal catheter body, an inflatable tube, a drug injection tube and an inflatable cuff. A seam is arranged at one end of the tracheal catheter body, the inflatable cuff is arranged at the other end of the tracheal catheter body and comprises an inner bag and an outer bag externally wrappingthe inner bag, the outer bag is made of medical controlled-release membrane, both the inflatable tube and the drug injection tube are connected with the wall of the tracheal catheter body and buried in a wall layer, the inflatable tube axially extends along the tracheal catheter body in the wall layer of the tracheal catheter body and is communicated with a cavity formed by the inner bag, and thedrug injection tube axially extends along the tracheal catheter body in the wall layer of the tracheal catheter body and is communicated with a cavity formed by the outer bag. The functions of the tracheal catheter are more diverse, more requirements can be met, medical accidents are decreased, and the pain of patients is relieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a continuous controlled-release medication type tracheal tube. Background technique [0002] The endotracheal tube is an indispensable product for anesthesia, first aid, and intensive care. The existing endotracheal tube is very irritating to the patient, especially when the endotracheal tube is inserted and pulled out, it often causes severe stress in the patient. It is commonly used clinically in the trachea. The method of applying local anesthetics on the surface of the catheter balloon reduces the stimulation to the patient. However, after the endotracheal tube is inserted into the trachea, local anesthetics cannot be applied again, and the endotracheal tube needs to be left in the patient’s trachea for a long time. The effect of anesthetic drugs gradually disappears, and when the extubation is performed, the strong stimulation will cause the patient's severe stress response, e...

AI Technical Summary

Problems solved by technology

[0002]The endotracheal tube is an indispensable product for anesthesia, first aid, and intensive care. When the endotracheal tube is placed in the trachea, local anesthetics are often applied on the surface of the endotracheal tube balloon to reduce the stimulation to the patient. It needs to be left in the patient's trachea for a long time, and the effect of the pre-applied local anesthetic will gradually disappear. When the tube is extubated, the strong stimulation will cause the patient's severe stress response and endanger the safety of the patient.

In addition, for some patients, after indwelling the endotracheal tube, some specific drugs, such as vasoactive drugs, hormones, antibiotics, etc., can be given through the endotracheal tube, and sometimes need to be administered slowly to make the blood drug concentration of the patient stable, while the existing endotracheal tubes cannot meet this requirement
