Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tracheotomy tubes. Background Art
[0002] Tracheotomy to establish an artificial airway is an important measure to solve airway obstruction and improve ventilation function in critically ill patients. However, after tracheotomy, the upper airway loses its warming, humidifying, and purifying effects on the inhaled gas, causing the respiratory mucosa to dry easily, sputum to thicken easily, and sputum plugs to form, which reduces the defense function of the respiratory system and creates conditions for pathogen invasion. Therefore, reducing the loss of water in the respiratory tract and strengthening airway humidification in patients after tracheotomy are important measures to keep the airway moist, dilute sputum, and keep the airway unobstructed, and are also the key to reducing the occurrence of lung infections.
[0003] At present, the generally accepted nasal oxygen tube is composed of an air supply tube, an endotracheal tube interface and a splash cap. The gas enters the patient's lungs through the air supply tube and then exhales through the outlet. Due to individual differences among patients, the required flow rate cannot be met by the air supply port. When the patient inhales, he needs to inhale part of the gas from the outlet, resulting in a decrease in the molecular weight of water in the gas and a decrease in the saturated humidity of water molecules in the gas. As a result, the patient's airway humidification effect cannot be effectively guaranteed. Sputum crusts and tube blockage often appear in the endotracheal tube, endangering the patient's life. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a nasal oxygen tube for tracheotomy patients in view of the above-mentioned technical deficiencies. While ensuring smooth air intake on the original gas supply side, a retention tube is added on the exhalation side to increase the humidity of the inhaled air, thereby diluting the patient's sputum and making it easier to discharge.
[0005] The technical solution adopted by the utility model is to provide a nasal oxygen tube for tracheotomy patients, comprising
[0006] An endotracheal tube interface, configured to be connected in a sealed manner to a endotracheal tube worn on a patient's tracheostomy portion;
[0007] The central tube has one end sealed and connected with the endotracheal tube interface, and the other end is a sputum suction port, and a cap is connected to the sputum suction port; a first interface is arranged on the side wall of the end of the central tube close to the endotracheal tube interface; a second interface is arranged on the side wall of the end of the central tube close to the sputum suction port; the second interface and the first interface are staggered in the axial direction of the central tube, and the angles of the first interface and the second interface with the central tube in the direction of the sputum suction port are both less than 90 degrees;
[0008] An air delivery pipe, one end of which is sealed and connected to the first interface, and the other end of which is connected to an external air intake device;
[0009] The retention tube has one end sealedly connected to the second interface and the other end communicated with the external atmosphere.
[0010] To further optimize the technical solution, a retention tube of a nasal oxygen tube used for tracheotomy patients is a shapeable telescopic hose.
[0011] To further optimize the technical solution, a central tube of a nasal oxygen tube used for tracheotomy patients is axially rotatably sealed and plugged into the interface of the endotracheal tube.
[0012] To further optimize the technical solution, a central tube of a nasal oxygen tube used for tracheotomy patients comprises a first tube segment and a second tube segment; the first interface is connected to the side wall of the first tube segment; the second interface is connected to the side wall of the second tube segment; the first tube segment and the second tube segment are axially rotatable and sealed in a plug-in fit.
[0013] To further optimize the technical solution, the inner wall of a retention tube of a nasal oxygen tube used for tracheotomy patients is coated with a hydrophilic coating.
[0014] To further optimize the technical solution, a retention tube of a nasal oxygen tube used for tracheotomy patients is made of PET, and the inner wall of the retention tube is a rough surface treated with corona.
[0015] In this technical solution, the retention tube can form a relatively closed section of airway, collect and retain the heat and moisture in the patient's exhaled gas, reduce water evaporation, have no irritation to the respiratory tract, and make the gas inhalation closer to the physiological state. The retention tube and the air supply tube are staggered, and the angle between them and the central tube in the same direction of the suction port is less than 90 degrees. The pressure of the airflow entering and discharging is relatively small. At the same time, it ensures that the suction port and the endotracheal tube interface are coaxial and do not interfere with the patient's sputum suction. The distance between the air supply tube and the endotracheal tube interface is closer than that of the retention tube. When inhaling, the oxygen in the air supply tube is inhaled first, and then the retained gas exhaled from the retention tube is supplemented, which can ensure the utilization rate of oxygen.
[0016] The structure of the retention tube is set as a shapeable telescopic hose, so that the length of the retention tube can be adjusted through the expansion and contraction of the structure, and the respiratory dead space volume suitable for the patient can be adjusted according to the vital capacity, gas flow rate, humidity and blood gas analysis indicators of different patients.
[0017] The connection between the central tube and the endotracheal tube interface is achieved by a rotatable sealing plug-in method, and the central tube adopts a two-stage rotatable sealing plug-in structure, which can realize the relative rotation freedom of the air supply tube and the central tube as well as the retention tube and the central tube. In this way, the patient can rotate the two tubes to the appropriate positions according to changes in the condition and adjustment of body position, making it more convenient to wear.
[0018] Coating the inner wall of the retention tube with a hydrophilic coating, or roughening the inner wall with a corona treatment process, can increase the adsorption rate of exhaled water vapor. The condensed water vapor will appear as a water film with a large surface area on the inner wall of the retention tube, rather than in the form of water droplets. This makes it easier to recycle the water vapor when gas is exhaled from the retention tube. BRIEF DESCRIPTION OF THE DRAWINGS
