Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to an intelligent automatic sputum aspirator.
Background
Sputum aspiration refers to a method for sucking secretion of respiratory tract through oral cavity, nasal cavity and artificial airway (tracheotomy) to keep respiratory tract unobstructed and prevent complications such as aspiration pneumonia, atelectasis and asphyxia. The preparation is suitable for patients with coma, especially patients with the possibility of asphyxia in the sputum, and patients who need intratracheal administration, contrast medium injection or sputum dilution.
Sputum aspiration is important, particularly for patients with difficult sputum evacuation. Sputum causes a more intense cough only when cilia exercise deduces it from the pharynx. If the cilia function is reduced, accumulation of sputum is likely to occur when the amount of sputum is large. Become a high-order factor in the occurrence of pneumonia. Therefore, sputum aspiration techniques are used in airway care in many departments. However, sputum aspiration techniques have the following problems: 1. the suction force of the sputum suction process can cause the damage of airway mucosa of a patient; 2. massage the strong nail cartilage of the great injury of the laryngeal and knot; 3. the electric sputum aspirator is used for preventing stimulation to cause intracranial pressure to be increased by 4 and vascular fragility when suffering from hypertension and cerebral blood diseases, so that the electric sputum aspirator is used for aggravating illness and increasing cerebral blood quantity to easily cause cerebral hernia, and the aspiration needs to be controlled in a cautious and short way. However, there are contradictions as follows: if the attractive force of sputum suction is too large, the four points of danger are easily caused; however, if the force of sucking sputum is insufficient, accumulation of sputum cannot be effectively cleared. In this case, only by increasing the number of times of low negative pressure suction, an effective sputum excretion function can be achieved. However, this would severely increase the workload of the nurse. In the current clinical working situation, it is not realistic.
