Intelligent sputum suction device

Abstract

The invention relates to an intelligent sputum suction device, which comprises a sputum suction detection warning device, a sputum suction action operation arm, a center controller, a sputum suction tube clean replacing box, a sputum suction and collection device and a sputum suction tube, wherein the sputum suction detection warning device is used for detecting and judging whether the sputum suction is needed or not; the sputum suction action operation arm clamps, pulls and feeds the sputum suction tube, and is provided with a pressure sensor used for detecting the tube feeding resistance; a clean sputum suction tube and a waste sputum suction tube are placed in different regions in the sputum suction tube clean replacing box; a sputum collecting bottle is arranged in the sputum suction and collection device; an infrared ray detector is configured for analyzing sucked sputum; and a central controller receives various detection signals, controls the actions of forward pushing, backward retreating, rotating and the like of the sputum suction tube, and controls the starting and the stopping of the negative pressure pump. The intelligent sputum suction device has the advantages that the sputum suction operation can be effectively realized; the sputum suction position is not limited in the front section of an artificial airway; the deep sputum suction can be effectively realized; the condition of infection risk increase due to mutual pollution of the sputum of a patient and sputum suction equipment is effectively avoided; and the injury on the respiratory tract mucosa of the patient caused by sputum suction operation is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an intelligent sputum suction device. Background technique [0002] The self-defense mechanism of the respiratory system depends on the ciliated columnar epithelium on the tracheal and bronchial mucosa and the mucus-secreting goblet cell structure. The rhythmic movement of the ciliated cells from the inside out drives the particles deposited on the mucosa to be discharged into the throat along with the mucus. When the mucus accumulates into phlegm, it is excreted through the cough reflex. Only when mucociliary transport is functioning properly can secretions from the distal airways be transported to the larger airways where they are cleared by the cough reflex. However, for patients who have established an artificial airway such as tracheal intubation or tracheal cannula, the artificial airway ensures the smoothness of the airway and saves the lives of critically ill pat...

Problems solved by technology

[0004] In the sputum suction devices disclosed in Chinese patents CN 104703646 A and CN 103330981 A, the sputum suction tube is fixed at the lower part of the artificial airway and opens at the front part of the artificial airway. Realize a complete replacement of suction operation

And the lack of design for cleaning the suction line increases the risk of respiratory infection

In addition, the negative pressure mode of the above patents is timing suction or judging whether sputum suction is needed according to the airway pressure, which does not meet the requirements of sputum suction according to the patient's needs proposed in the existing guidelines. Airway pressure is only one of the indications for sputum suction and cannot Reasonable reminder of need for suction
