Problems solved by technology

For critically ill patients who need tracheal intubation, the general sputum removal device is less effective. For example, some gas resonance sputum removal devices used in the oral cavity cannot be used normally due to oral or nasal intubation. At the same time, the external gas resonance device , the vibration source is far away from the lungs and the lower trachea, and the impact of gas vibration is weak, while increasing the vibration intensity is easy to cause injury and is not easy to control. It causes injury, which is not conducive to rehabilitation exercises; at the same time, patients with tracheal intubation use oxygen supply tubes to breathe, and when using airbags for positioning, due to long-term blockage and extrusion, it is easy to cause necrosis of some cells in the trachea, affecting the trachea's autonomous sputum movement. Not conducive to rehabilitation exercise

Abstract

The invention discloses a sputum expulsion device for severe patients in neurosurgery, which relates to the technical field of medical devices. The device comprises an endotracheal intubation mechanism, a vibration mechanism and a sputum suction mechanism. The tracheal intubation mechanism comprises an oxygen supply tube; The head and the middle of the oxygen supply pipe are fixedly sleeved with apositioning air bag. The vibration mechanism comprises a vibration detection system, a positioning plate and two vibration bladders; A magnetic needle is fixedly installed inside that vibration capsule. A drive motor is slidably installed in the chute; The output end of the driving motor is fixedly connected with a permanent magnet. The permanent magnet is arranged in parallel with the magnetic needle. The sputum suction mechanism comprises a tool table, a negative pressure pump, a sputum suction box and a sputum suction tube. The invention has the beneficial effects that the vibration sourcepenetrates into the airway in combination with the oxygen supply tube for the patient who needs the tracheal intubation to supply air, the influence of the gas vibration on the lung and the trachea is more effectively realized, and the rehabilitation exercise is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical instruments. Background technique [0002] An important defense mechanism commonly seen during coughing and expectoration. Some critically ill patients cannot complete sputum discharge independently, and need to use vibration sputum discharge or sputum suction to discharge sputum. For critically ill patients who need tracheal intubation, the general sputum removal device is less effective. For example, some gas resonance sputum removal devices used in the oral cavity cannot be used normally due to oral or nasal intubation. At the same time, the external gas resonance device , the vibration source is far away from the lungs and the lower trachea, and the impact of gas vibration is weak, while increasing the vibration intensity is easy to cause injury and is not easy to control. It causes injury, which is not conducive to rehabilitation exercises; at the same time, patients with tracheal intubatio...
