Description

Technical Field

[0001] This invention relates to the field of ventilator technology, and more specifically, to a ventilator tubing with a spiral flow guiding structure and a suction-sensing mechanism, and its application method. Background Technology

[0002] A ventilator typically consists of a main unit and tubing. It achieves ventilation by establishing a pressure difference between the atmosphere and the alveoli. During inhalation, gas is directly applied with positive pressure (usually exceeding alveolar pressure) through the tubing, forcing gas into the lungs. During exhalation, the pressure is reduced to expel gas from the alveoli.

[0003] Existing ventilator tubing is usually a single straight tube. If it encounters sputum, it is very easy to cause blockage or the inner diameter of the tube to become smaller due to the stickiness of the sputum, which affects normal ventilation. The method of directly adjusting the inspiratory pressure through the main unit has a limited threshold for adjusting the inspiratory pressure in order to avoid harming the human body. Therefore, this method can only solve a small part of the problem. There is a need for a ventilator tubing with a spiral flow guiding structure and a sensor-assisted sputum suction method. Summary of the Invention

When the end of the first pipe and the end of the second pipe are in contact, the electrode plate connects the two contacts; the first sub-spiral contacts the sputum and stops rotating due to the obstruction of the sputum. At this time, the first pipe continues to rotate. Relying on the threaded engagement between the extension tube and the inner wall of the second pipe, the first pipe and the second pipe approach and fit together.

[0011] The ventilator tubing with a spiral flow guiding structure and suction sensing described in this invention includes a torque detection sensor on the drive unit. When the torque exceeds a set threshold, it is determined that the device is in suction mode; otherwise, it is determined that the device is in non-suction mode. When the processor unit receives the non-suction mode signal from the torque detection sensor, it controls the inner tube to exit the temporary air supply and suction mode.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0028] The third mode is the sputum suction mode; in the second mode, when the first sub-spiral 30 comes into contact with sputum, it stops rotating due to the obstruction of sputum. At this time, the first pipe 20 continues to rotate. Relying on the threaded engagement between the extension pipe 22 and the inner wall of the second pipe 21, the first pipe 20 and the second pipe 21 approach and fit together.

The structure is simple, the reset reliability is good, and the torsion spring itself does not need to move. The elastic torque for reset can be provided by the movable cooperation between the end and the movable hole.

At this time, the first pipe continues to rotate. Relying on the threaded engagement between the extension tube and the inner wall of the second pipe, the first pipe and the second pipe come close together and fit together.
