Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disposable laryngeal mask airway tube. Background Art

[0002] In the clinical rescue of patients with cardiac and respiratory arrest, especially those who need cardiopulmonary resuscitation, it is of great significance to establish an effective artificial airway at the first time to improve the success rate of rescue. When patients need surgery and receive general anesthesia, in order to maintain their breathing and ventilation, patients need to receive airway treatment devices, such as endotracheal intubation, etc., but the aforementioned devices are easy to cause cardiopulmonary reactions in patients during use, and even cause respiratory damage; and in the process of emergency treatment, precious time is often wasted due to the high operating technology. At present, the laryngeal mask airway tube device has been successfully applied to surgical anesthesia and rescue of critically ill patients, especially for a large number of patients with difficult airways. However, in the prior art, because one end of the disposable laryngeal mask airway tube is to be connected to the ventilator, the connection fixation is not high, the connection is unstable, and it directly affects the patient's life safety.

[0003] The utility model with application number 202022940440.X discloses a disposable laryngeal mask airway catheter, including a mask bag, which is connected to a ventilator, a reinforcement ring is provided at one end of the ventilator away from the mask bag, a thread A is provided at the connection between the surface of the ventilator and the reinforcement ring, a thread B is provided on the inner wall of the reinforcement ring, the inner diameter of one end of the reinforcement ring is larger than the inner diameter of the other end, and both ends of the reinforcement ring are in an open state. The utility model is implemented by putting the ventilator on the outlet pipe of the ventilator, and then threading the thread B in the fixing ring with the thread A on the periphery of the ventilator. Since both ends of the fixing ring are in an open state and the inner diameter of one end is larger than the inner diameter of the other end, a clamping force is achieved for the fit between the ventilator and the outlet pipe of the ventilator during the process of threading from the large diameter end to the small diameter end, which greatly improves the stability of the connection between the ventilator and the ventilator.

[0004] However, the technical solution in the above utility model still has room for improvement: although the threaded connection is achieved by threading the thread B in the fixing ring with the thread A on the outer periphery of the ventilation tube, and although the threaded connection has good self-locking performance, it will wear and loosen over time, causing air leakage in the connection between the ventilation tube and the ventilator, thus endangering the patient's life safety. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a disposable laryngeal mask airway tube, which solves the problems raised by the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A disposable laryngeal mask airway catheter comprises a mask bag, a ventilation tube and an air supply tube.
