Humidification oxygen inhalation connector for tracheotomy

Abstract

The invention provides a warm-humidification oxygen inhalation connector for tracheotomy, and relates to the technical field of medical auxiliary equipment. One end of the oxygen inhalation catheter extends into a trachea after a patient is cut open, and the other end of the oxygen inhalation catheter is connected with an oxygen supply end; the oxygen temperature humidifying mechanism is located in the oxygen inhalation catheter, oxygen entering from the oxygen inhalation catheter can pass through the oxygen temperature humidifying mechanism and is discharged from the other end of the oxygen inhalation catheter, and the oxygen discharged from the oxygen inhalation catheter is humidified; the two ends of the oxygen inhalation catheter can be directly connected with an oxygen source and an incised trachea respectively, the dry and cold state of oxygen can be improved through the oxygen inhalation connector, and the oxygen can be warmed and humidified, so that the oxygen is more suitable for breathing of a patient, the problems of airway inflammation and the like are avoided, and the oxygen supply safety after the trachea is incised is improved; the oxygen inhalation connector is simple in structure and flexible to use, the manufacturing cost is greatly reduced, therefore, the treatment cost of the patient is greatly changed, the burden of the patient is relieved, and the oxygen inhalation connector is more beneficial to being popularized and used.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a temperature-humidified oxygen-absorbing joint for tracheotomy. Background technique [0002] In the treatment of anaerobic infection, CO poisoning, air embolism, decompression sickness, hypoxic ischemic encephalopathy, brain trauma, cerebral hemorrhage and cerebral infarction, if the condition is severe and the coma time is longer, the It is easy to cause pulmonary infection, and some patients may experience sputum obstruction in the lower respiratory tract, difficulty breathing, and impaired respiratory mechanism. In order to manage the respiratory tract and treat patients, tracheotomy or tracheal intubation should be performed in time; A special breathing tube is connected to the oxygen supply source so that the patient can adjust to a normal breathing state; and due to the change of the breathing passage, the breathing cannula is inserted into the larynx ...

AI Technical Summary

Problems solved by technology

[0004] 1. The straight-line catheter supplies oxygen to the metal casing. Although the operation of oxygen inhalation is convenient, the straight-line method leads to potential safety hazards

[0005] 2. Some medical staff use disposable gloves to make their own connectors, open the ends of the gloves and tie them to the oxygen supply pipe and sleeve respectively to achieve leak-free oxygen inhalation, but this method is inconvenient for oxygen inhalation and sputum suction. It complies with medical materials and hygienic standards, and cannot be carried out on a large scale. It also has the problem of oro-nasal shunt, and cannot fully increase the concentration of oxygen inhalation.

[0006] 3. At present, the most used in China is to directly cover the head and neck of the patient through the plastic hood, and directly send oxygen into the hood through the oxygen supply pipeline for the patient to breathe. This device is easy to operate for oxygen inhalation, but the gas exhaled by the patient Arranged in the hood, resulting in low oxygen concentration, which cannot meet the national standard; the exhaled gas cannot be discharged outside the cabin, causing the oxygen concentration in the oxygen chamber to exceed the national control standard, and the sputum suction operation is inconvenient, posing a safety hazard; The air in the mask is not circulated, the patient's head and face are stuffy and sweaty, the catheter is noisy when delivering oxygen, and the comfort is poor; the mask is reused by many people, and the dirt left on the mask by the patient's cough or breathing is not easy to clean, and there is cross-infection risks of

[0007] 4. At present, the ideal oxygen inhalation method is to supply oxygen through a pneumatic ventilator in the oxygen chamber, which can effectively increase the oxygen concentration and reduce the oxygen concentration in the oxygen chamber. It is only suitable for critically ill patients who have no spontaneous breathing or weak breathing. The cost of equipment is high, and the charges are expensive, and most hospitals in China have not yet equipped with this device

[0008] In summary, patients with tracheotomy undergoing hyperbaric oxygen therapy can be roughly divided into two categories: one with a plastic tracheostomy tube; the other with a metal tracheal cannula; However, the supplied oxygen does not pass through the mouth and nose, making it too dry and cold, which may cause airway inflammation and other problems in patients; the current solution is usually to connect the oxygen source to a ventilator or a specialized oxygen therapy device, and then It outputs oxygen for the patient to breathe, and this type of equipment is expensive, which greatly increases the cost of treatment and cannot be accepted by ordinary patients
