Abstract: An intelligent exhaled sputum-suction and inhaled oxygen-supply device is provided, including a sputum-suction and oxygen-supply tube unit, a gas-regulating unit and a control unit. The sputum-suction and oxygen-supply tube unit includes a major oxygen-supply tube and a major sputum-suction tube, and the gas-regulating unit includes an oxygen-supply module supplying oxygen to the major oxygen-supply tube, a sputum-suction module, and a respiration sensor configured to sense a breathing state of a patient. The control unit is electrically connected with the sputum-suction module and the respiration sensor, and the control unit controls 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 so as to simplified the operation processes.

Abstract: The invention is an endotracheal intubation for preventing injury to throat, vocal cords and trachea. The endotracheal intubation comprises a hollow intubation body with a variable outer diameter. The hollow intubation body comprises a front end and a tail end, an inner intubation wall and an outer intubation wall, and having a retracted state with a smaller outer diameter and an expanded state with a larger outer diameter. When the endotracheal intubation inserted into a patient’s trachea needs to be replaced, as long as the hollow intubation body of the new endotracheal intubation is in the retracted state, it can be inserted into the hollow intubation body to be replaced, and when reaching the position, the hollow intubation body to be replaced is withdrawn, and finally the new hollow intubation body is changed into the expanded state, i.e. the replacement operation of the endotracheal intubation is completed.

Abstract: A percussion apparatus for sputum clearance includes a percussion unit, a drive unit, and a control unit, the percussion unit includes a percussion member and an angle detector, the angle detector is configured to detect an included angle between the reference plane and a horizontal plane, the control unit is electrically connected with the drive unit, and when the included angle conforms to a preset angle, the control unit controls the drive unit to drive the percussion unit to periodically percuss, which greatly saves the manpower and increase the efficiency of sputum clearance.

Abstract: A sitting type spinal traction and disc massage apparatus includes a seat member, a seat pad disposed atop the seat member, a fixing member straddling the seat member and the seat pad and connected to the seat member to fix hips of a user to the seat member, and a moving backrest board disposed atop a rear end of the seat member. The moving backrest board is movable relative to the seat member. A restricting member straddles and is connected to the moving backrest board to fix the user's upper body to the moving backrest board. A lifting unit is disposed below the moving backrest board to move the moving backrest board upwardly from the seat member to stretch the user's spine. A vibrating unit is disposed within and vibrates the seat pad.
