Problems solved by technology

When the muscles of the pharyngeal wall completely lose their tension, the pharyngeal polyps collapse, and the tongue completely falls back, forming a complete obstruction of the upper airway, that is, the collapse causes apnea syndrome, leading to apnea and suffocation. Intubation; but when the patient is under general anesthesia, the accumulation of pharyngeal polyps will make it impossible to complete the intubation work. In this case, the trachea can only be cut to ensure smooth breathing. trauma and financial burden

Abstract

The invention discloses an anti-suffocation pharyngeal catheter device and a manufacturing mold of the catheter device. The catheter device is a flexible catheter (1), the flexible catheter (1) comprises a flexible straight tube portion (11) and an arc-shaped tube portion (12), the arc-shaped tube portion (12) is located at the front end of the straight tube portion (11), and the radian of the arc-shaped tube portion (12) is consistent with the radian of human soft palate; when the flexible catheter (1) extends from human lower nasal passage into the pharynx, the arc-shaped tube portion (12) is placed in the pharynx supports the collapsed part of the pharyngeal polyp; and at the same time, the manufacturing mold of the flexible catheter device is also disclosed. The device can be insertedinto the pharynx from the nostril before a general anesthesia operation of a patient, and even if the patient has pharyngeal polyp collapse during the operation, the breathing can also be kept unobstructed because of the enhanced support of the arc-shaped tube portion, thus avoiding the surgical risk and trauma of tube cutting.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-suffocation pharyngeal catheter device and a manufacturing mold thereof. Background technique [0002] The upper airway of adults is the pharyngeal cavity, and its front and side walls are not supported by bony tissue. It is kept open by muscle tension on the pharyngeal cavity wall. When the patient is under anesthesia, the pharyngeal cavity can be narrowed to varying degrees due to muscle relaxation and the tongue falling backward. If the pharyngeal cavity is significantly narrowed, a hypopneic state is produced during inspiration due to rapid airflow through the uvula, tongue base, and epiglottis. When the muscles of the pharyngeal wall lose their tension completely, the pharyngeal polyps collapse, and the tongue completely falls back, forming a complete obstruction of the upper airway, that is, the collapse causes apnea syndrome, leading to apnea and suffocati...
