Description

An endotracheal tube connector

technical field

The utility model belongs to the technical field of medical instruments, in particular to a joint for a trachea catheter or a trachea catheter.

Background technique

The existing methods and ways of oxygen supply clinically are: 1. Nasal congestion or nasal cannula oxygen inhalation method: easy to operate, and the nose hair has a filtering and cleaning effect on oxygen. However, oxygen can irritate the nasal mucosa, which can cause hoarseness, dry nasal mucosa, crusting, and epistaxis. Because oxygen cannot enter the airway during exhalation, it will be lost in the nasal cavity, which will affect the effect of oxygen therapy. 2. Oxygen inhalation by face mask: For children and uncooperative persons, place the mask 1-3cm away from the patient's mouth and nose to give oxygen. Those with severe hypoxia can tightly cover the patient's mouth and nose and fix it with an elastic band. The oxygen inhalation method of the mask It does not stimulate the airway mucosa of the patient, has a large oxygen flow rate, and the concentration can be high, and the inhaled oxygen concentration (FiO2) can reach 40% to 50%, but the oxygen consumption is large, and it hinders the patient's language communication, eating and expectoration. 3. Intravenous oxygen supply method: Internal oxygen supply for injection (carbonic acid amide hydrogen peroxide for injection) is a safe and effective method for the treatment of hypoxemia. First aid, nasal cavity disease is not suitable for nasal congestion oxygen inhalation and those who cannot tolerate nasal congestion oxygen inhalation. 4. Intratracheal oxygen supply: In recent years, for patients with difficult-to-correct hypoxemia at home and abroad, the oxygen supply catheter is introduced into the trachea at a distance of 3 to 5 cm from the carina with a fiberoptic bronchoscope or a cricothyroid puncture cannula, and the trachea is administered. Internal low-flow oxygen supply can reduce oxygen consumption by more than 50%, and has good oxygen therapy effect, and is suitable for long-term application, which has attracted the attention of clinicians.

Patent No. CN200920034448.X discloses a porous oxygen suction head and side V-shaped tracheal cannula, including an oxygen supply nasal cannula, which is characterized in that the oxygen supply nasal cannula that can be used alone is a porous oxygen suction head (1), and its There are three small holes on the side of the closed end of the hose. The small holes are circular or/and oval. The distance from the end to the first small hole is 4-6 mm, and the distance between the hole side and the hole side is 4-8 mm. The ventilation area of each small hole is 3.1-7.1 square millimeters. The technical solution of this patent achieves the purpose of easy acceptance and proper fixation of the patient's nasal catheter oxygen inhalation, and promotes the effect of quick recovery of the patient's condition, but it does not overcome the defects of nasal congestion or nasal catheter oxygen inhalation.

Mechanical ventilation after tracheal intubation and tracheotomy has become more and more widely used in clinical practice. After the patient's condition is stable, during the process of taking the tube offline, humidified airway and oxygen supply are often used to assist the patient to breathe. Humidification with the trachea. If the humidification is not in place, it can cause poor phlegm discharge, phlegm scab formation, and then lung infection.

When a patient is given oxygen through a tracheal tube or a tracheal tube, clinically, the oxygen tube and humidification tube are usually inserted into the tracheal tube or the tracheal tube after adjusting the aerobic concentration, and fixed with adhesive tape. As a result, the oxygen tube will come out, and the adhesive tape will often cause unstable fixation. Improper fixing position will affect the patient's breathing, and the adhesive tape will remain on the tape after repeated pasting. When connecting the ventilator pipeline, you must first pull out the oxygen tube and humidification tube, and then connect the ventilator. back into the endotracheal tube or tracheostomy tube. In addition, the usual practice when suctioning sputum is to first pull out the oxygen tube and humidification tube from the endotracheal tube or tracheotomy tube, and then perform the sputum suction operation, and then insert the oxygen tube and humidification tube back after the operation is completed. However, if you do not take out the oxygen tube and humidification tube when suctioning, the oxygen tube and humidification tube will occupy part of the lumen of the tracheal tube or tracheostomy tube, making it difficult to insert the thick suction tube. It is necessary to pull out the oxygen tube and the humidification tube. Even if the thin suction tube can be inserted, it is easy to take out the oxygen tube and the humidification tube together when pulling it out, which brings great inconvenience to the clinical work. At the same time, the oxygen tube and humidification tube occupy the endotracheal tube, resulting in increased airway resistance. During the above-mentioned operations, due to the pulling out of the oxygen tube and the humidification tube, the patient is in a state of interrupting oxygen supply for a period of time, especially for patients who cannot tolerate hypoxia, it is easy to aggravate hypoxia, resulting in tissue damage and dysfunction , and the humidification is not in place, it can cause poor expectoration, phlegm scab formation, and then lung infection. In addition, when the end of the oxygen tube or humidification tube is pressed into the endotracheal tube or tracheal catheter, it will inevitably cause the bending of the oxygen tube or humidification tube, so that the air flow in the tube is not smooth; The endotracheal tube or tracheotomy tube is taken out, and it needs to be fixed again after suctioning, which increases the chance of infection; and the two tubes are more likely to slip off, which cannot guarantee the effect of oxygen supply and humidification.
