Tracheal catheter cuff pressure controller

Abstract

The invention discloses a tracheal catheter cuff pressure controller which comprises a pressure adjustment valve and an air storage bag, wherein the pressure adjustment valve comprises a scaleplate with values, an adjustment knob and a spring; a designation card is arranged on a middle column of the adjustment knob, and continuous threads are formed on the middle column; the adjustment knob is rotated to make the designation card move left and right along with the rotating middle column to reach a required set pressure value; the end part of the adjustment knob is connected with an air release valve 14; a connector connected with a tracheal catheter cuff for inflation is arranged on one side of the air storage bag; an automatic inflating connector is arranged at the lower part of the air storage bag. The tracheal catheter cuff pressure controller is easy and convenient to operate, can be quickly and automatically inflated and deflated, and can dynamically monitor pressure on the tracheal catheter cuff in the whole process to reduce damage to the tracheal mucous.

Description

technical field [0001] The invention relates to a medical device, in particular to a tracheal tube cuff pressure controller for reducing tracheal mucosal damage caused by tracheal intubation and general anesthesia. Background technique [0002] The role of catheter cuff inflation after general anesthesia tracheal intubation is to prevent air leakage, reflux and aspiration during ventilation, improve the quality of ventilation, ensure the effect of mechanical ventilation and reduce the leakage of inhaled anesthetics. Because the pressure of the catheter cuff is too small, the airway cannot be effectively closed, affecting the effect of effective positive pressure mechanical ventilation, and at the same time it will increase the occurrence of aspiration, resulting in a significant increase in the incidence of postoperative pulmonary complications, and the pressure of the catheter cuff is too high , The catheter cuff compresses the tracheal wall, causing ischemia, necrosis, and...

AI Technical Summary

Problems solved by technology

Because the pressure of the catheter cuff is too small, the airway cannot be effectively closed, affecting the effect of effective positive pressure mechanical ventilation, and at the same time it will increase the occurrence of aspiration, resulting in a significant increase in the incidence of postoperative pulmonary complications, while the pressure of the catheter cuff is too high , the catheter cuff compresses the tracheal wall, causing ischemia, necrosis, and shedding of the compressed local tracheal mucosa. In severe cases, local ulcers may occur, and ring scars may form after healing, resulting in tracheal stenosis
