Intelligent exhaled sputum-suction and inhaled oxygen-supply device

An intelligent exhaled sputum-suction and inhaled oxygen-supply device, configured to be applied to a respiratory tract of a patient, including:

• a sputum-suction and oxygen-supply tube unit, including a major oxygen-supply tube and a major sputum-suction tube configured to be disposed within the respiratory tract;
• a gas-regulating unit, including an oxygen-supply module, a sputum-suction module, a minor oxygen-supply tube communicating the oxygen-supply module with the major oxygen-supply tube, a minor sputum-suction tube communicating the sputum-suction module with the major sputum-suction tube, and a respiration sensor configured to sense a breathing state of the patient;
• and
• a control unit, electrically connected with the sputum-suction module and the respiration sensor, the control unit configured to controll the sputum-suction module to draw gas from the minor sputum-suction tube when the respiration sensor senses that the patient is in an exhalation state;
• wherein the respiration sensor is a pressure sensor or a flow sensor, and the control unit is configured to determines that the patient is in an inspiratory state when the respiration sensor senses a negative airway pressure or an inhaled flow;
• wherein the intelligent exhaled sputum-suction and inhaled oxygen-supply device further includes a base, a driving unit and a front adapter unit, the driving unit includes a first motor, a moving platform and a second motor, the first motor is disposed on the base and electrically connected with the control unit, the moving platform is drivable by the first motor to move back and forth in a front-rear direction, the second motor is electrically connected with the control unit, the second motor includes a motor body disposed on the moving platform and a hollow drive shaft, the hollow drive shaft is disposed through the motor body in the front-rear direction and is drivable by the motor body to rotate about an axis extending in the front-rear direction, the hollow drive shaft has a guiding hole extending therethrough, the front adapter unit includes a front mounting portion disposed in front of the second motor and a front rotating portion rotatably disposed on the front mounting portion and connected with a front end of the hollow drive shaft, the front mounting portion has a front outer connecting hole, an end of the front outer connecting hole is open forward, another end of the front outer connecting hole is connected with the minor oxygen-supply tube, the front rotating portion has a front inner connecting hole penetrating therethrough and communicated with the guiding hole, the major oxygen-supply tube is stretchably sleeved to a front side of the front mounting portion, the major sputum-suction tube is disposed within the major oxygen-supply tube and connected to a front side of the front rotating portion so as to be communicated with the front inner connecting hole and be drivable to rotate with the front rotating portion by the hollow drive shaft, and the control unit is configured to control the first motor and the second motor to drive the major sputum-suction tube to move and rotate.
