An intelligent sputum suction device

Abstract

An intelligent sputum suction device, including a sputum suction detection and alarm device, a sputum suction operation arm, a central controller, a sputum suction tube cleaning and replacement box, a sputum suction collection device and a sputum suction tube, and the sputum suction detection and alarm device is used for detection and judgment Whether it is necessary to suck sputum, the operation arm of the sputum suction action clamps the suction and delivery suction tube, which is equipped with a pressure sensor for detecting the resistance of the delivery tube; clean and discarded sputum suction tubes are placed in partitions in the sputum suction tube cleaning and replacement box, and the sputum suction tube is There is a sputum collection bottle in the liquid suction and collection device, and it is equipped with an infrared detector to analyze the sucked sputum. The start and stop of the pressure pump, the invention can effectively realize the sputum suction operation, the sputum suction site is not limited to the front part of the artificial airway, it can effectively realize deep sputum suction, and effectively avoid the mutual contamination between the patient's sputum and the sputum suction equipment, which increases the risk of infection To reduce the damage to the patient's respiratory mucosa during the suction operation.

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...

AI Technical Summary

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
