A sputum discharge device for critically ill patients in neurosurgery

Abstract

The invention discloses an expectoration device for critically ill patients in neurosurgery, and relates to the technical field of medical instruments. It includes a tracheal intubation mechanism, a vibration mechanism and a sputum suction mechanism; the tracheal intubation mechanism includes an oxygen supply tube; the head and the middle of the oxygen supply tube are fixedly sleeved with positioning airbags; the vibration detection mechanism includes a vibration detection System, positioning plate and two vibrating capsules; magnetic needles are fixedly installed inside the vibrating capsule; the output end of the drive motor is fixedly connected to the driving gear; the upper and lower sides of the front end of the positioning plate are rotated and installed with pinion gears, and the position of the pinion gear and the vibrating capsule One-to-one correspondence; permanent magnets are installed on the end faces of the auxiliary gears; the permanent magnets are arranged parallel to the magnetic needles; the sputum suction mechanism includes a tool table, a negative pressure pump, a sputum suction box and a sputum suction tube. The beneficial effects of the present invention are: for patients who need gas supply by endotracheal intubation, combined with the oxygen supply tube, the vibration source goes deep into the airway, more effectively realizes the impact of gas vibration on the lungs and trachea, and is beneficial to rehabilitation exercise.

Description

technical field [0001] The invention relates to the technical field of medical instruments. Background technique [0002] An important defense mechanism common 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 intubation use o...

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
