Description

An adult thin replaceable tube reinforced tracheal tube

technical field

The utility model belongs to the technical field of medical equipment, and relates to an adult thin replaceable tube reinforced trachea catheter.

Background technique

Emergency patients with subglottic edema, tumor or tracheal stenosis due to airway obstruction and insufficient effective ventilation lead to hypoxia and carbon dioxide accumulation in the body, resulting in clinical manifestations such as cyanosis, increased heart rate, and elevated blood pressure. Coma and even respiratory and cardiac arrest may occur. Rapid and effective implementation of endotracheal intubation and establishment of artificial airways are one of the important measures to save patients' lives. However, for such patients admitted to the emergency department, due to their critical condition, it is often impossible to comprehensively assess the subglottic edema, mass or tracheal stenosis in a timely manner. , can only observe the situation of the upper glottis respiratory tract, but the lower respiratory tract, especially the degree of tracheal stenosis can not be judged, so how to choose a tracheal tube, and then successfully implement tracheal intubation, establish an artificial airway, the prognosis of patients and Outcomes are critical. The conventional model adult reinforced endotracheal tube is designed to match the normal adult trachea, and the length and diameter of the endotracheal tube have corresponding standards. Obviously, this type of endotracheal tube is not suitable for patients with subglottic edema, mass or tracheal stenosis. If the conventional adult strengthening tracheal tube is used to establish an artificial airway, not only the success rate is low, but also it may aggravate tracheal edema, and even lead to the rupture and bleeding of the tumor, thereby further aggravating dyspnea and worsening the patient's condition.

Utility model content

The utility model discloses an adult thin replaceable tube reinforced tracheal catheter, which is used for the establishment of artificial airway in emergency patients with subglottic edema, tumor or tracheal compression and stenosis with difficulty in breathing. The use of the catheter can not only establish an artificial airway in a timely and effective manner, but also reduce further damage to the respiratory tract, thereby improving the oxygenation of the patient and saving the patient's life. Provide protection for further treatment of patients.

The technical scheme of the present utility model is as follows:

An adult thin replaceable tube reinforced tracheal catheter, the catheter is composed of a single-lumen airway, a leak-proof cuff, a catheter joint, and a spiral tube changer, the length of the single-lumen airway is 35-38 cm, and the inner diameter of the single-lumen airway It is 4.0-5.0 mm, and the leak-proof cuff is sealed and sleeved on the tube body of the single-lumen airway. The leak-proof cuff is communicated with the one-way valve through the inflation tube. The air conduit is threadedly connected with the conduit joint, the conduit joint is connected to the ventilator threaded pipe, the spiral tube changer is a solid conduit, and one end of the spiral tube changer is matched with the single-lumen air conduit screw joint.

The single-lumen airway and spiral tube changer are tough, non-toxic, non-irritating to the pharynx, larynx, and trachea tissue, and do not cause allergic reactions. Plastic catheters with smooth walls.

The advantages of the utility model are: 1. The tracheal catheter has the length of a conventional adult tracheal catheter, but the inner diameter of the catheter is the diameter of a pediatric reinforced tracheal catheter. This design can not only meet the tracheal diameter of patients with subglottic edema, tumor or tracheal stenosis, reduce secondary damage to the patient's airway, but also have sufficient length to pass through the tracheal stenosis, thereby effectively establishing an artificial airway. Maintain the patient's respiratory function, save the patient's life, and improve the patient's prognosis; 2. After effective medical treatment, the subglottic edema has been eliminated, and the subglottic tumor has been removed, the screw joint of the tracheal tube can be replaced by a matching section. At this time, the tracheal tube has the function of a tube changer, which can guide the insertion of a conventional tracheal tube, so that the tracheal tube can be successfully replaced, and the damage caused by the conventional tracheal intubation to the patient can be avoided; 3. The utility model has the ability to operate Simple, safe and reliable, it can not only quickly and effectively improve the oxygenation of patients, but also save medical resources, and has wide application and promotion value in clinical emergency rescue work; 4. The single-lumen airway and spiral tube changer are both tough in texture , Non-toxic, non-irritating to the pharynx, larynx, trachea and other tissues, and does not cause allergic reactions to plastic catheters with smooth walls. The use of disposable sterile plastic catheters is not only convenient to use, but also eliminates the risk of cross-infection.

Detailed ways

An adult thin replaceable tube reinforced tracheal catheter is composed of a single-lumen airway tube 7 , a leak-proof cuff 1 , a catheter joint 3 , and a spiral tube changer 4 . The length of the single-lumen airway tube 7 is the same as that of the adult tracheal tube, that is, the length of the single-lumen airway tube 7 is 35-38 cm, and the distance from the central incisor to the middle section of the airway tube 7 is 20-21 cm, which can be matched during intubation The length of the adult airway, while the diameter of the single-lumen airway tube is the same as that of the pediatric tracheal tube, that is, the inner diameter of the single-lumen airway tube 7 is 4.0-5.0 mm. Can be matched with single lumen airway 7. For emergency dyspnea patients with subglottic edema, mass or tracheal compression stenosis, a thinner catheter diameter can not only satisfy the patient's ventilation, but also will not cause secondary damage to the stenotic trachea. The leak-proof cuff 1 is inflated by the one-way valve 2 and is a leak-proof device for the single-lumen airway 7, which can not only prevent vomit, blood or oropharyngeal secretions from flowing into the trachea, but also prevent air leakage during mechanical ventilation. After inflation, the single-lumen airway 7 can be fixed in the trachea to ensure smooth breathing. The catheter connector 3 can be connected to a ventilator to maintain the oxygen supply and carbon dioxide discharge of the patient through mechanical ventilation to ensure the safety of the patient's life. respiratory support.

When the patient has subglottic edema and subglottic mass and other emergency breathing difficulties that cannot be clearly observed by laryngoscope, the adult thin replaceable tube can be used to strengthen the tracheal tube to relieve the obstruction, and a single-lumen airway can be inserted. Insertion length requirements (male 22-24 cm, female 21-23 cm); use one-way valve 2 to inflate the leak-proof cuff 1 to ensure airtight airways, while preventing blood and oral secretions from entering the lungs; catheter Connector 3 can be connected to the ventilator to ensure that the ventilator can supply oxygen to the patient. At this time, the patient can proceed to the next step under the condition of ensuring ventilation. When the airway obstruction is relieved, remove the catheter connector 3 and replace it with the spiral tube changer 4. The diameter of the spiral tube changer is the same as the inner diameter of the single-lumen airway. 4.0-5.0 mm, not only can be matched and connected, but also smaller than the inner diameter of the conventional tracheal tube 7.0, the gas in the leak-proof cuff 1 is evacuated, and the guide can be placed into the conventional tracheal tube, which can not only ensure the success of tracheal intubation, but also Avoid the damage to the patient caused by repeated routine tracheal intubation.
