technical field

Background technique

Endotracheal intubation and tracheotomy are one of the commonly used first aid methods for rescuing critically ill patients. They can improve dyspnea caused by various reasons, correct the patient's hypoxic state, improve ventilation function and effectively remove airway secretions. Both intubated and tracheostomized patients usually require continuous oxygenation and airway humidification. At present, the disposable artificial nose commonly used clinically only has oxygen inhalation pipes and sputum suction apertures and does not have a special airway humidification device. Specialized humidification only relies on the restrictive function of the original artificial nose. In this way, for patients with viscous sputum and lung infection, during offline training, phlegm may form on the trachea wall due to insufficient airway humidification. Scabs and phlegm plugs ultimately affect the patient's condition treatment. Therefore clinically, the connector skin needle of the disposable infusion set is usually fixed on the sputum suction aperture of the artificial nose with adhesive plaster, and routine humidification and sputum suction are carried out. In this method, when sucking phlegm, the humidification tube needs to be taken out from the suction aperture of the artificial nose after the humidification liquid is inserted, and it needs to be put back and fixed again after the sputum suction is over. increase the chance of infection. Usually, the adhesive tape used to fix the humidification tube is easily soaked by sputum, the viscosity decreases, and the fixation is easy to loosen. In addition, factors such as the impact force on the tube when the patient coughs or the gravity effect when the disease requires a special position, etc. It is more likely that the humidification tube will loosen, leading to the interruption of humidification and the formation of phlegm scab, which will cause serious consequences to the patient.

Further, a humidification fluid flow regulating valve is installed on the humidification pipeline, which can adjust the flow of the humidification fluid according to the consistency of the patient's sputum and the water content of the filter layer.

Further, the humidification pipeline is installed on the side wall of the cover body, and the mouth of the humidification pipeline enters the cover body through the side wall.

Further, the humidification liquid is physiological saline.

Further, the distance between the nozzle of the oxygen inhalation pipeline and the inner wall of the housing is greater than 4 cm, so that the air flow forms a vortex in the inner cavity of the housing.

Further, the diameter of the oxygen inhalation pipeline is 1.8mm, which can meet the requirement of high flow oxygen supply.

Further, the sputum suction pipe is connected with negative pressure to suck out the sputum.

Further, the cover body is cylindrical.

Further, the filter layer is filter paper.

The artificial nose provided by the utility model is connected with the tracheal cannula, and the setting of the humidification pipeline can continuously drip the humidification liquid, maintain the water content of the filter layer, ensure that the air inhaled by the patient has a certain humidity, and make the patient feel comfortable. When the patient's sputum is viscous, the dripping rate of the humidification solution can be increased, and when the patient's sputum is thin, the rate of dripping of the humidification solution can be correspondingly reduced or stopped. The humidification pipeline, oxygen suction pipeline and sputum suction pipeline are all dedicated pipelines, which do not interfere with each other, neither affect the use of the ventilator nor affect sputum suction, and can also maintain and adjust the air humidity. The humidification pipe is firmly installed on the cover body, and even if the patient coughs on the pipe to produce impact or gravity when the disease requires a special position, it will not cause the humidification pipe to loosen.

Detailed ways

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

The artificial nose shown in FIGS. 1 and 2 includes a cylindrical cover body 1 , a moisture-absorbing and air-permeable filter layer 2 , an oxygen inhalation pipeline 3 and a humidification pipeline 4 . When the artificial nose is put on the tracheal tube, it is in an upright state. The bottom end of the cover body 1 is the connection part 6 connected with the tracheal tube. The connection part 6 communicates, and the other end of the sputum suction pipe 5 is connected to the negative pressure. When sucking sputum, the sputum is sucked out through the tracheal tube, the connection part 6 and the sputum suction pipe 5 . The cover body 1 is filled with a filter layer 2, and the oxygen inhalation pipeline 3 and the humidification pipeline 4 are installed on the cover body 1 above the filter layer 2 for dripping the humidification liquid into the filter layer 2 for wet After the chemical liquid enters the filter layer 2, it is absorbed by the filter layer 2 and spreads throughout the filter layer 2. Oxygen enters the cover body 1 from the oxygen inhalation pipeline 3, and is inhaled into the patient's respiratory tract after being filtered by the filter layer 2. Since the filter layer 2 has been wetted by the wetting liquid and has a certain water content, oxygen will be humidified when passing through the filter layer 2 .
