Background
At present, acute obstruction of respiratory tracts at the throats or the upper parts of the throats or coma due to trauma, foreign matters, inflammation and the like, or coma due to brain trauma, resuscitated patients, patients after chest trauma or major operations, and patients with severe lung infection and dyspnea can recover the respiratory tracts and improve the ventilation function of the lungs in order to relieve the laryngeal obstruction, facilitate the suction of lower respiratory secretions and rescue the lives of the patients, often perform tracheotomy, place tracheal tubes at incisions and supply oxygen to the patients through connecting oxygen suction tubes to the tracheal tubes when necessary.
In clinical medicine, a breathing machine is generally adopted to assist in ventilation and oxygen supply for patients. Before the ventilator is removed and the tracheal cannula is removed, a Spontaneous Breathing Test (SBT) is clinically performed to determine the Spontaneous respiratory function of the patient. Among them, directly cutting off the breathing machine and inhaling oxygen through the T-tube (i.e. oxygen tube) is an important method for SBT experiments. However, many departments or wards are not equipped with breathing machines, and the cost of breathing machines is higher for patients who only need to inhale oxygen.
At present, the oxygen tube special for the trachea cannula body is not used, a patient of the trachea cannula body is cut off by the nose end of the common oxygen tube, one side of the common oxygen tube is tied tightly, and the other side of the common oxygen tube extends into the trachea cannula body. The defects of material waste and time consumption in manufacturing are existed; the presence of a ventilated dead space; difficult to fix and easy to fall out when the patient coughs; the adhesive plaster is easy to leave adhesive plaster marks after being fixed by the adhesive plaster, so that the infection risk is increased, and the medical adhesive plaster is frequently stuck repeatedly or polluted by sputum and humidifying fluid to cause viscosity loss so as to cause the slippage of the oxygen uptake catheter. In addition, in the fixing process, the catheter is easy to pop out when being inserted too shallow, and is easy to break when being inserted too deep, so that great hidden danger is brought to oxygen safety. And the rubberized fabric fixing method is not favorable for nursing operation.
Therefore, how to solve the above problems is a matter of research for those skilled in the art.
