A suction robot

Abstract

The invention discloses a phlegm suction robot. The robot comprises a phlegm suction portion, a fixing portion and a functional portion and can further comprise a moving portion, wherein the phlegm suction portion is a phlegm suction device which is connected with an external control panel, provides negative pressure for sucking phlegm, collects phlegm and flushes a phlegm suction pipe; the fixing portion is used for fixing the phlegm suction pipe and an artificial airway; the functional portion is used for sending the phlegm suction pipe in and drawing the phlegm suction pipe out and comprises a stepper motor and a linear guide rail, a slide block is arranged on the linear guide rail and connected with a mechanical arm used for clamping the phlegm suction pipe, the stepper motor drives the slide block and the mechanical arm to move on the linear guide rail back and forth through a synchronous conveying belt, the mechanical arm is connected with a steering engine so that the mechanical arm can swing in the direction perpendicular to the linear guide rail; the moving portion is of a moving flat car structure, carries the phlegm suction portion, the fixing portion and the functional portion and drives the phlegm suction robot to move. By means of the phlegm suction robot, phlegm suction operation can be simulated, the phlegm suction robot serves as teaching equipment to conduct exhibition for students, in addition, the phlegm suction robot can be used clinically in practice, automatic phlegm suction operation is achieved, and work intensity of nurses is alleviated.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a sputum suction robot. 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 patients, but on ...

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

Moreover, 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 Unable to reasonably prompt the need for suction
