Description

Trachea cannula oxygen atomization humidification air exchange auxiliary device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an oxygen-driven atomization humidification and ventilation auxiliary device for trachea intubation.

Background

The breathing machine is an important device for manually replacing the autonomous ventilation function in clinic, is widely used for respiratory failure caused by various reasons, anesthesia respiratory management during major operations, respiratory support treatment and emergency resuscitation, and occupies an important position in the modern medical field, and the breathing machine can play important roles in preventing and treating respiratory failure, reducing complications, saving and prolonging the life of a patient. An intubation tube is required to be inserted into an trachea of a patient with an invasive respirator, when the body of the patient using the invasive respirator is improved and the patient can breathe independently, the respirator can be removed, but the intubation tube in the trachea can not be removed immediately at a time for various reasons, so that subsequent oxygen therapy and atomization therapy can only be carried out together with the intubation tube, the conventional oxygen therapy mode with the intubation tube is generally oxygen supply in an open airway, namely the air outlet end of the oxygen therapy tube is directly plugged into the intubation tube for oxygen therapy, but the normal respiratory function of a human body is damaged by the intubation tube, the water in the trachea is seriously shunted, the sputum discharging capability of the patient is weakened, if humidification and thin sputum are not carried out in time, the secretion in the trachea is thickened, the sputum suction operation is influenced, the drying in the trachea is easily caused, and sputum scab is finally formed, the intubation is blocked to influence the effective ventilation of a patient, in order to avoid the situation, the existing method is to drip 2-3 ml of humidification liquid into the tracheal intubation every 1-2 hours, and drip 2-3 ml before sputum suction, but the humidification mode not only consumes the energy of medical staff, but also has higher requirements on the operation level of the medical staff, and once the control is not good, the probability of pneumonia of the patient is greatly improved.
