Description
Technical Field
The utility model belongs to the technical field of medical instruments, and particularly relates to a novel double-balloon tracheal catheter capable of spraying medicine.
Background
Endotracheal tubes are medical devices that are inserted into the trachea and/or bronchi of a patient to create a temporary artificial respiratory pathway for the patient, particularly for patients who are unable to breathe spontaneously. The common intubation head has one or two cuffs which can play the roles of fixing the intubation and sealing the airway after being inflated, or does not have the cuffs. The cannula shaft is typically made of a polymeric material with a wire coil embedded therein to improve radial strength and axial flexibility. Part of the cannula body is made of anti-laser material or multiple layers to resist laser irradiation. Is an intubation tube inserted into the trachea of a patient nasally/orally or percutaneously. One end of the air inlet pipe is connected with an anesthesia respirator through a breathing pipeline so as to maintain the breath of the patient. Is provided aseptically and is disposable.
In clinical practice, when general anesthesia or respiratory failure ventilator treatment is performed, it is necessary to insert a tracheal tube into the trachea or bronchus through the nose, mouth, or trachea incision. The main aim is to maintain effective alveolar ventilation and oxygen supply; the secretion of the air passage is cleared in time, and the air passage is kept smooth; facilitating manual or mechanical ventilation. The problems existing at present are as follows: 1 during the intubation or retention period of the tracheal catheter, the intubation and retention period of the tracheal catheter, transient and strong cardiovascular reactions such as blood pressure rise, heart rate increase and the like and stress reaction are often caused, the risk of accidents such as cerebral apoplexy, myocardial ischemia and the like is often increased, and even the risk of sudden death is increased by inducing the prolongation of QT interval [1 ]. 2 adverse events such as tracheal injury, postoperative throat pain and the like can be caused when the cuff pressure of the tracheal catheter pressed by the tracheal mucosa is too high for a long time; 3 during the retention period of the tracheal catheter, the intratracheal administration can not reach the full contact with mucosa around the tracheal wall.
In order to reduce adverse reactions caused by stress during tracheal intubation to the maximum extent and overcome the defects of the double-balloon tracheal catheter in the prior art: although the two air bags can be replaced for inflation, the fixed position of the air bag can be changed, and the damage of the fixed position air pipe caused by long-time compression is avoided; however, since the positions of the two balloons are fixed, when the position of the endotracheal tube is not changed, the positions where the two balloons are in contact with each other are not changed, and the two fixed points are replaced at the two fixed points for a long time, and the two fixed points are also damaged by compression.
