Description

A multifunctional nasopharyngeal ventilation catheter

technical field

The utility model relates to the technical field of medical devices, in particular to a multifunctional nasopharyngeal ventilation catheter.

Background technique

As a commonly used rescue method in first aid, tracheal intubation is one of the most widely used, most effective and quickest methods in airway management, and is a basic skill that medical staff must master. The reported incidence of difficult endotracheal intubation ranges from 1.5% to 13%, and difficult intubation is more likely to occur in suboptimal settings outside the operating room, such as emergency rooms, intensive care units (ICUs), patient wards, and even outside the hospital. Awake nasal intubation is the most effective way to deal with difficult airways.

In the process of tracheal intubation, due to the structural characteristics and design shortcomings of the tracheal intubation catheter, complications such as laryngeal edema, glottis injury, intraoral injury, respiratory tract injury, and local bleeding may occur. The probability of occurrence, the use of visual tracheal intubation is a good choice.

After tracheal intubation is used to anesthetize patients before surgery, in clinical use, there may be various reasons such as insufficient humidification in the cannula, inappropriate sputum suction methods, inability of patients to expectorate sputum, and lack of body fluids resulting in viscous sputum. The sputum adheres to the wall of the tracheostomy airway for a long time and accumulates too much to form a sputum scab. The current clinical treatment for this situation is as follows: after instilling 0.5ml of normal saline into the opening of the tracheal intubation, use a sputum suction tube to suck out the secretions in the airway and intubation from near and far along the tracheal intubation. Because the inner diameter of the tracheal intubation tube is circular, and its length is 250mm and a certain arc, the dripped physiological saline flows from a high position to a low position; at the same time, it is impossible to arbitrarily absorb the secretions sticking to the tracheal wall, and it cannot be effectively cleaned. .

At present, the clinical nasotracheal intubation is often guided by a video laryngoscope or a fiberoptic bronchoscope. The operation is relatively complicated and the cost is relatively high, which is difficult to popularize in many primary hospitals. Furthermore, the function of the existing tracheal tube is not perfect, and medical staff may need to use different instruments to perform operations in steps to perform sputum suction and gas monitoring when performing intubation-related operations. produce infection or increase the incidence of other complications.

Example 1

Take a patient who needs long-term indwelling tracheal intubation for nasotracheal intubation as an example. First, connect the wireless micro-camera to a slender steel cable and place it in the tracheal intubation tube. After the patient is subjected to surface anesthesia of the nasopharyngeal mucosa, the transnasal visual ventilation tube 1 is intubated. Insert, by pulling the bellows cable 7, adjust the bending degree of the bellows 31 at the front end of the ventilation tube 1 to adapt to the patient's nasal cavity and airway anatomical structure characteristics. The micro camera is taken out, then the balloon 22 is inflated, and the cannula is fixed.

After the intubation is successful, connect the air bag gas injection port 8 to the external sensor air bag pressure detection device, adjust the pressure of the air bag 22 to a suitable pressure, inject air, and fix the catheter. The ventilator is connected to the ventilator through the upper port 9 of the ventilation tube, the gas monitoring tube 6 is connected to the gas monitor, and other functions are adopted according to the specific conditions of the patient. If it is observed on the gas monitor that the patient's breathing is abnormal or there is foreign body obstruction in the airway, connect the suction tube negative pressure connector 5 at the end of the suction tube 24 to suction sputum.

In this embodiment, the airbag 22 is protruded outward to form a ring-shaped sputum collecting groove. The bottom of the sputum collecting groove has a first suction hole 23. The sputum collecting groove can accommodate the secretions sliding off the outer wall of the tube.
