Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a portable sputum aspirator.
Background
COPD and bronchiectasis are common respiratory diseases, the prevalence rate of COPD of people over 30 years old in China is reported to be 6.2%, and respiratory diseases mainly based on COPD become the first cause of death in rural areas and the 4 th cause of death in cities in China. Patients suffering from COPD acute exacerbation and bronchiectasis complicated infection have increased sputum amount and are sticky, if sputum cannot be effectively discharged, a large amount of purulent sputum is accumulated in respiratory tracts, which is a place for bacterial breeding, the sterilization effect of antibiotics can be reduced, and partial patients even have to suck sputum in airways through a fiberoptic bronchoscope. Therefore, the safe and effective sputum excretion method with less complications and pain is the key treatment content for patients with more sputum. Stimulating cough, effective back percussion and body position drainage are powerful measures for assisting patients in sputum excretion, and negative pressure suction can help patients with weak sputum excretion to relieve respiratory obstruction. Research shows that the deep suction of the airway with the indications is beneficial to thoroughly cleaning the endocrine in the respiratory tract, improving the hypoxia of the organism and prolonging the sputum suction interval time. The suction of airway secretions means that sputum, blood, mistakenly sucked gastric contents and other foreign matters in the airway cannot be effectively removed due to the reduction of cough capacity of a patient, and the sputum, the blood, the mistakenly sucked gastric contents and other foreign matters need to be removed by external suction so as to keep the airway smooth. The establishment of an artificial airway causes the original function of the upper airway to be lost, and particularly the use of a large amount of sedatives significantly reduces the cough ability of the patient. Therefore, in patients with poor cough ability, especially those with established artificial airways, the attraction of airway secretions is already a technique that the caregivers of the patients must master, playing a crucial role in the treatment and rehabilitation of the patients. Continuous oxygen supply, low negative pressure and intermittent negative pressure suction can reduce the incidence of complications such as hypoxemia and respiratory mucosa injury caused by sputum suction.
At present, in clinical practice, hospitals often adopt a central negative pressure aspirator to suck sputum, and household sputum suction devices are also available in the market. However, the existing sputum suction devices suck secretions into a container through a sputum suction pipe for placement, after sputum suction is completed, necessary materials in the container need to be poured and cleaned, the secretions are communicated with the outside, and the secretions are infected by nursing staff easily due to a large number of viruses and bacteria and are easy to spread.
