Embodiment Construction
[0011] exist figure 1 Among them, the motor 13 drives the screw rod 12 to rotate forward, and the screw rod sleeve 11 drives the connecting rod 10 and the 4 valves to move forward together. figure 1 state, inhalation state. The blower fan 20 operates to generate negative pressure at the air inlet 21, and the fresh air passes through the opened valve 4 8, space 4 4, air intake pipe 16, air inlet 21, fan 20, air exhaust port 22, air outlet pipe 15, space 1, and opened Valve two 6, space two 2, new trachea 17, nasal mask 19 enter the human body. Though nasal mask 19 has been communicated with new trachea 17 and waste gas pipe 18, because valve 3 7 has been closed this moment, fresh air can only enter nasal mask 19 and enter human body backward. The aperture 23 on the dividing plate 9 just allows the connecting rod 10 to pass through, the gap is very small, and the leakage of air is negligible. The small hole 23 on the partition 9 and the fulcrum 24 with holes play the role of ...

The invention discloses a double-tube breathing machine which is high in ventilating efficiency. The breathing machine is mainly composed of a fan, an airflow change-over valve, a motor, a screw rod and a screw rod sleeve. The screw rod is driven to do forward rotation or reverse rotation along with the forward rotation or reverse rotation of the motor; and along with the forward rotation or reverse rotation of the screw rod, the screw rod sleeve, a connecting rod and four valve units the airflow change-over valve are pushed to move forwards or backwards, so that the valve units in the airflow change-over valve are opened or closed. As the valve units in the airflow change-over valve are opened or closed, a relation that a fan air inlet and a fan air outlet are connected to a fresh air tube and a waste gas tube is converted. When the airflow change-over valve is switched to an inhaling state along with the rotation of the motor, fresh air, which is inhaled by virtue of the fan from outside, is blown into a human body by virtue of the fresh air tube which is connected to a nasal mask; and when the airflow change-over valve is switched to an exhaling state along with the rotation of the motor, waste gas from the human body is pumped by the fan by virtue of the wast gas tube which is connected to the nasal mask and the waste gas is discharged outside. By carrying out the two processes in an alternative mode, an effect of assisting the human body in breathing is achieved. An airflow in the fresh air tube is independent from that in the waste gas tube without communication, so that fresh air is inhaled and waste gas is discharged.
Description
[0001] Technical field [0002] The invention relates to a ventilator, in particular to a double-tube ventilator capable of high-efficiency ventilation. Background technique [0003] At present, known ventilators are all single-tube ventilators, mainly composed of a breathing host, a single-tube ventilator, and a nasal mask. The ventilation tube communicates with the breathing host and the nasal mask. The breathing host provides power to supply the user with fresh air and remove exhaust gas. For the convenience of description, fresh air is hereinafter referred to as fresh air. Because the ventilation tube is a single-tube structure, fresh air and exhaust gas are all entered or discharged from one tube, and the volume of the tube is greater than 500 milliliters, while the amount produced by each exhalation cycle or inhalation cycle of a person is less than 500 milliliters. There will be such a phenomenon, the exhaust gas has just been exhaled and all the nasal mask has enter...
