However, for such emergency hospitalization patients, due to critical conditions, the condition of subglottic edema, tumor or tracheal stenosis cannot be timely and comprehensively evaluated, even if a difficult airway treatment tool such as a visual laryngoscope, a visual nylon laryngoscope and the like is applied, the condition of the supraglottic respiratory tract can only be observed, but the degree of the lower respiratory tract, especially the tracheal stenosis cannot be judged, so how to select the tracheal catheter, further successfully implement tracheal intubation and establish an artificial airway is very important for prognosis and outcome of the patient. The conventional adult strengthening tracheal catheter is designed for matching with a normal trachea of an adult, and the length and the pipe diameter of the tracheal catheter have corresponding standards. Obviously, such endotracheal tubes are not suitable for patients with subglottic edema, tumors, or stenotic airways. If the artificial airway is established by adopting the conventional adult reinforced tracheal catheter, the success rate is low, and the tracheal edema can be aggravated, even the tumor is damaged, cracked and bleeding is caused, so that the dyspnea is further aggravated, and the condition of a patient is worsened.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an adult thin type replaceable tube reinforced tracheal catheter for establishing artificial airway of patients with subglottic edema, tumor or trachea pressed narrow emergency dyspnea. The use of the catheter not only can timely and effectively establish the artificial airway, but also can reduce the further damage to the airway, thereby improving the oxygenation of the patient, saving the life of the patient, ensuring the insertion of the conventional tracheal cannula after the airway is blocked and contacted, and providing guarantee for the further treatment of the patient.
The technical scheme of the utility model as follows:
the thin replaceable reinforced tracheal catheter for adults comprises a single-cavity air duct, a leakage-proof cuff, a catheter joint and a spiral tube exchanger, wherein the length of the single-cavity air duct is 35-38 cm, the inner diameter of the single-cavity air duct is 4.0-5.0 mm, the leakage-proof cuff is hermetically sleeved on a tube body of the single-cavity air duct and communicated with a one-way valve through an inflation tube, the leakage-proof cuff is inflated by the one-way valve and is in threaded connection with the catheter joint, the catheter joint is connected with a threaded pipeline of a respirator, the spiral tube exchanger is a solid catheter, and one end of the spiral tube exchanger is matched with the spiral joint of the single-cavity air duct.
The single-cavity airway tube and the spiral tube exchanger are smooth-walled catheters made of plastic, which are tough in texture, non-toxic, non-irritating to pharynx, larynx and tracheal tissues and free of causing anaphylactic reaction.
The utility model has the advantages that: 1. the tracheal catheter has the length of a conventional adult tracheal catheter, but the inner diameter of the tracheal catheter is the diameter of a reinforced tracheal catheter for children. The design not only can satisfy the tracheal tube diameter of patients with subglottic edema, tumor or tracheal compressed stenosis and reduce the secondary damage to the airway of the patients, but also has enough length to pass through the tracheal stenosis, thereby effectively establishing an artificial airway, maintaining the respiratory function of the patients, rescuing the lives of the patients and improving the prognosis of the patients; 2. after the subglottic mass is removed by effective medical treatment, the spiral joint of the tracheal catheter can be replaced by a section of catheter matched with the spiral joint, and the tracheal catheter has the function of a tube replacing device and can be guided to be inserted into a conventional tracheal catheter, so that the tracheal catheter can be successfully replaced, and the damage to a patient caused by conventional tracheal intubation can be avoided; 3. the utility model has the advantages of simple operation, safety and reliability, not only can rapidly and effectively improve the oxygenation of patients, but also can save medical resources, and has wide application and popularization value in clinical emergency rescue work; 4. the single-cavity airway tube and the spiral tube changer are smooth-walled catheters made of plastic, which are tough in texture, non-toxic, non-irritating to tissues such as pharynx, larynx, trachea and the like and do not cause anaphylactic reaction. The disposable sterile plastic catheter is used, so that the use is convenient, and the risk of cross infection is avoided.

Detailed Description
An adult thin-type replaceable tube reinforced tracheal catheter consists of a single-cavity tracheal tube 7, a leakage-proof cuff 1, a catheter joint 3 and a spiral tube exchanger 4. The length of the single-cavity air duct 7 is the same as that of an adult tracheal catheter, namely the length of the single-cavity air duct 7 is 35-38 cm, the distance from a central incisor to the middle section of the air duct of the single-cavity air duct 7 is 20-21 cm, the length of the adult respiratory tract can be matched during intubation, the diameter of the single-cavity air duct is the same as that of an infant tracheal catheter, namely the inner diameter of the single-cavity air duct 7 is 4.0-5.0 mm, the single-cavity air duct 7 is placed into a trachea through a glottis by means of a laryngoscope, and the duct joint 3 can be matched with. For emergency treatment dyspnea patients with subglottic edema, tumor or tracheal stenosis, the thinner catheter tube diameter can not only meet the ventilation of the patients, but also cannot cause secondary damage to the narrow trachea. The leakproof cuff 1 is inflated by the one-way valve 2, is a leakproof device of the single-cavity air duct 7, can prevent vomit, blood or oropharynx secretion from flowing into the trachea, can also prevent air leakage during mechanical ventilation, and can fix the single-cavity air duct 7 in the trachea after the cuff is inflated, so as to ensure smooth respiration. The catheter connector 3 can be connected with a breathing machine, oxygen supply and carbon dioxide discharge of a patient are maintained through mechanical ventilation, life safety of the patient is guaranteed, after obstruction of an airway is relieved, the spiral tube changer 4 can be used for guiding the patient to be placed into a conventional tracheal catheter, and breathing support of the patient is guaranteed.
