Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical ventilators, and in particular to a fixer for a front nasal catheter cap of a non-invasive ventilator. Background Art
[0002] A non-invasive ventilator is a device that replaces the traditional intubation tube with a breathing nasal mask or nasal plug. The nasal mask is buckled on the patient's mouth and nose or the nasal plug is inserted into the nose for air supply, thereby solving the disadvantage that the traditional intubation tube needs to be inserted into the patient's trachea. Non-invasive ventilators are often used as auxiliary breathing devices for newborns. Although this type of ventilator will not cause trauma to the patient's body, when wearing a nasal mask or nasal plug, considering that the newborn patient cannot accurately cooperate with the wearing, it is easy for the nasal mask or nasal plug to fall off due to the shaking of the patient's head, resulting in air leakage at the connection between the non-invasive ventilator and the patient, making it impossible to accurately maintain the pressure of the non-invasive ventilator, thereby reducing the ventilation effect. It is necessary to set a corresponding strap structure on the breathing nasal mask or nasal plug. Because the breathing nasal mask or nasal plug structure is connected to the airway of the equipment, the airway is usually heavy and will pull the nasal mask or nasal plug during use, thereby causing the nasal mask or nasal plug to fall off, or shaking and scratching the patient's nose or head during use. Therefore, for such usage, it is necessary to design a device structure suitable for newborn patients to fix the front nasal catheter of the ventilator. Summary of the invention
