Abstract

The invention relates to the technical field of sputum suction, and provides a sputum suction device for nurses in an intensive care unit, which comprises a negative pressure box, wherein a liquid inlet, a liquid outlet, a handle, a control panel and an observation window are arranged on the negative pressure box, a central control module and a battery module are arranged in the control panel, a conveying shaft, a guide wheel and other structures are arranged, the conveying shaft is driven by a servo motor to drive a connecting belt to automatically convey a sputum suction tube, so that the sputum suction tube advances and retreats at a uniform speed, and meanwhile, sliding friction is converted into rolling friction by a guide ball protruding from the surface of the guide wheel, so that the resistance of the tube feeding and the mucous membrane stimulation of a patient are remarkably reduced. The operation is coordinated and controlled only by the control button instruction central control module, manual pushing and pulling are not needed, the operation flow is greatly simplified, the labor intensity of nurses is reduced, the operation stability and efficiency are improved, and the problems of complex operation and high infection risk in the prior art are solved.
