Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a sputum suction device with pressure sensing. Background Art

[0002] Tracheotomy generally refers to tracheotomy, which is a common surgery to relieve dyspnea caused by laryngeal dyspnea, respiratory dysfunction, and lower respiratory tract secretion retention. Its purpose is to relieve airway obstruction and allow patients to ventilate smoothly. As an important measure to rescue critically ill patients, tracheotomy is widely used in various surgeries and is often used to improve dyspnea caused by various reasons. Since the tracheotomy site of patients after tracheotomy is open, if the sputum in the patient's airway is not cleaned in time, the patient will cough the sputum into the air during coughing, thereby contaminating the nursing staff and the items around the patient, increasing the workload of the nursing staff. The existing sputum suction device lacks drainage components, resulting in slow sputum recovery, which is easy to cause airway obstruction in patients. The utility model patent with the publication number CN219743603U discloses a tracheostomy sputum collecting device. When the device is in use, the neck-worn device can assist the patient to fix the entire device on the neck, the tracheostomy tube is inserted into the patient's throat, and matches the surgical opening of the patient's throat. The sputum suction mechanism is opened, so that the sputum is transported along the transport suction tube connected to the tracheostomy tube, and the sputum is transported to the sputum collecting component. The sputum collecting component is detachably connected to the transport suction tube. When the sputum in the sputum collecting component accumulates to a certain amount, the sputum collecting component can be disassembled to clean the sputum collected therein. This method improves the efficiency of collecting and processing sputum and facilitates medical staff to clean up sputum. However, the device requires nursing staff to hold it to perform sputum suction on the patient. For patients with more sputum, their airways often cannot be cleaned in the first time, so nursing staff are required to watch the patient all night to prevent the patient's trachea from being blocked by sputum. This nursing method increases the workload of nursing staff.

[0003] How to solve the above problems has become a technical problem that needs to be solved urgently. Utility Model Content
