Description

Technical Field

[0001] The invention relates to the technical field of respiratory sputum suction devices, and in particular to an intelligent respiratory sputum suction device. Background Art

[0002] Sputum suction is commonly used in clinical practice for patients who have difficulty breathing due to thick sputum, inability to cough and expectorate, etc. It mainly uses the principle of negative pressure suction to suck out the sputum retained in the respiratory tract, which can promote airway patency, improve ventilation and infection. It needs to be performed by professional medical staff, and patients are not recommended to operate it themselves. Usually, before suctioning, it is necessary to check the doctor's instructions and explain the purpose of suction to the patient. The specific steps of suctioning include preparing suction equipment, checking equipment, adjusting patient posture, intubation and suction, postoperative cleaning, etc. When suctioning patients, the patient's respiratory tract is sometimes blocked by sputum accumulation, causing the body to be unconscious. Therefore, medical staff need to use a tongue depressor to open the patient's mouth and tongue to ensure the stable insertion of the suction tube. However, a medical staff member is still needed to assist in suctioning, which is very inconvenient. We propose an intelligent suction device for respiratory medicine. Summary of the invention

[0003] The purpose of the present invention is to provide an intelligent sputum suction device for respiratory medicine to solve the problems raised in the above background technology.
