Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a cough auxiliary protection device. Background Art

[0002] Coughing is a protective respiratory reflex of the human lung system to clear lung mucus from the respiratory tract. However, many patients with respiratory diseases, such as chronic obstructive pulmonary disease, produce excessive secretions in the respiratory tract and cannot effectively cough out secretions from the respiratory tract due to weakened cough airflow. However, mucus accumulates on the surface of the trachea, which affects the lung's function of outputting carbon dioxide and inhaling oxygen, and further leads to lung infection, inflammation and airway obstruction caused by atelectasis, ventilation and oxygen inhalation. It is very necessary to assist patients in coughing out lung mucus from their respiratory tract. Utility Model Content

[0003] The utility model aims to provide a cough assisting protection device, which mainly loosens viscous secretions and makes them fall off from the trachea surface by the vibration of airflow during inhalation through an inhalation oscillation mechanism, expands the airway through the positive pressure generated by an exhalation pressure regulating mechanism during exhalation, pushes the loosened secretions from bottom to top to the upper part of the airway and discharges them out of the body through coughing, thereby helping patients to clear excessive secretions in the airway.

[0026] Example 2

[0027] Instructions for use: When using the device, the user rotates the adjusting screw sleeve 32 counterclockwise to minimize the compression of the spring 32, and at the same time, turns on the power to check whether the electromagnet 44 can work normally. After the inspection, the mask 2 is worn on the face and is airtight, and the switch of the magnetic control unit 61 is turned on to make the electromagnet 44 work. When current is applied to the electromagnet 44, the second air-sealing rod 41 moves downward to interrupt the air intake. When there is no current in the electromagnet 44 and the patient does not inhale, the second air-sealing rod 41 remains in a closed state under the action of gravity. When the patient inhales, the second air-sealing rod 41 moves upward to allow air to enter the connector 1 and then enter the mask 2 to complete the inhalation, that is, during the patient's inhalation process, the magnetic control unit 61 provides a pulse current to the electromagnet 44 to make the second air-sealing rod 41 move up and down, so that the inhaled air vibrates to loosen the viscous secretions on the airway surface; when needed When the inhaled air is to be heated, the switch of the temperature control unit 62 is turned on to make the heating network 52 generate heat to heat the inhaled air. At the same time, the atomization interface 54 needs to be blocked to prevent the loss of hot air, so as to avoid the stimulation of cold air in cold weather conditions; when the patient exhales, the first air sealing rod 31 is pushed away by the exhaled gas, thereby exhausting the gas. At this time, the patient can rotate the adjustment screw sleeve 33 according to his own conditions to compress the spring 32, thereby increasing the pressure between the first air sealing rod 31 and the connector 1, so that a certain pressure needs to be reached in the device to exhaust the gas during exhalation, ensuring that the device is in a positive pressure state during exhalation, thereby expanding the patient's airway, and then causing the loose viscous substances on the surface of the airway to move upward along the inner wall of the trachea during the exhalation process; after using the device for multiple exhalations and inhalations, remove the mask 2 and blow hard to induce coughing to expel sputum.
