Description

Technical Field

[0001] This invention belongs to the field of medical auxiliary device technology, and in particular relates to a sputum suction device and method for postoperative care in thoracic surgery. Background Technology

[0002] A suction device typically consists of a negative pressure pump, a collection bottle, and a suction tube. The negative pressure pump creates a negative pressure environment inside the device. Under this negative pressure, outside air enters the suction device through the suction tube, while sputum is drawn in along with the air and then into the collection bottle. During use, healthcare professionals insert the suction tube into the patient's airway through the mouth or nose. They intermittently control the opening and closing of the negative pressure pump. When the pump is on, the suction tube is slowly withdrawn; once withdrawn a short distance, the pump is turned off, and this process is repeated. This ensures that each time negative pressure is applied, the suction focuses on removing sputum within a certain area around the suction tube. Continuous negative pressure is avoided, as it may cause the suction tube to become clogged with sputum, affecting the effectiveness of subsequent suctioning.

[0003] However, during each suctioning procedure, medical staff cannot repeatedly turn the suction device on and off for ease of operation. In addition, when too much sputum is removed from the suction tube, the low internal pressure of the suction tube may attract tissue in the throat, causing discomfort such as throat pain and increased coughing in the patient.
