Aspirator

Abstract

The invention discloses a spitting device which comprises a hollow communicating portion (1) and a phlegm accumulation portion (2). A tracheotomy pipe joint (3) and a phlegm accumulation cup joint (4) are arranged on the communicating portion (1), the phlegm accumulation portion (2) comprises a phlegm accumulation cup (8) which is connected to the phlegm accumulation cup joint (4), and a negative pressure joint and an air hole (11) are arranged on the phlegm accumulation cup (8). By the spitting device, automatic phlegm suction can be realized without manual operation, and environmental pollution caused by splashing of phlegm of a patient can be effectively avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a sputum suction device. Background technique [0002] Tracheotomy and indwelling ventilation tube is the most commonly used first aid measure in clinical practice to rescue acute respiratory failure and save patients' lives, but the open airway after operation will cause other problems: patients with respiratory diseases usually secrete more sputum, and often need Medical staff use sputum aspirators to suck sputum for patients at regular intervals. Most of the existing sputum aspirators cannot achieve sputum suction without unmanned operation. Therefore, the workload of medical staff is increased; The open tracheotomy and indwelling ventilation tube are directly connected to the outside world. When the patient coughs, the sputum will directly splash into the surrounding environment, pollute the ward, and easily cause cross-infection between patients and patients and between patien...

Problems solved by technology

[0002] Tracheotomy and indwelling ventilation tube is the most commonly used first aid measure in clinical practice to rescue acute respiratory failure and save patients' lives, but the open airway after operation will cause other problems: patients with respiratory diseases usually secrete more sputum, and often need Medical staff use sputum aspirators to suck sputum for patients at regular intervals. Most of the existing sputum aspirators cannot achieve sputum suction without unmanned operation. Therefore, the workload of medical staff is increased; The open tracheotomy and indwelling ventilation tube are directly connected to the outside world. When the patient coughs, the sputum will directly splash into the surrounding environment, pollute the ward, and easily cause cross-infection between patients and patients and between patients and medical staff; cold air Directly entering the patient's trachea, it is easy to form phlegm plugs and phlegm scabs, causing lung expansion or airway blockage, causing or aggravating lung infection; tiny dust in the air can enter the trachea and lungs with the patient's inspiratory airflow, Mild cases cause coughing and severe cases even cause lung damage to patients. Therefore, the current method is to cover a layer of gauze at the mouth of the tracheotomy and indwelling ventilation catheter to prevent dust from entering the air. However, patients often cough or change their positions. Make the gauze fall off, and the gauze is easy to form secondary pollution after the sputum sticks; in addition, placing the oxygen suction tube and the drip tube at the mouth of the ventilation catheter after the tracheotomy is easy to cause lung infection
