Subglottic aspiration device

Abstract

A computer-controlled vacuum suctioning device for subglottic aspiration, in which the timing of the pump operation is regulated so as to be synchronized with the operation of a mechanical respirator.

We claim: 
     
         1 . A vacuum suctioning device for subglottic aspiration, comprising a vacuum pump, wherein the timing of the pump is regulated by a controller comprising a computer. 
     
     
         2 . The device of  claim 1 , further comprising a high-pressure pump in communication with a liquid reservoir, said high-pressure pump being capable of generating a mist from a liquid contained in said reservoir. 
     
     
         3 . The device of  claim 2 , wherein said device is connected to a mechanical ventilator, and wherein the controller is programmed to operate the high-pressure pump only when the ventilator is applying negative pressure to a patient's lungs. 
     
     
         4 . The device of  claim 3 , wherein the controller is programmed to initiate suction with the vacuum pump prior to mist injection with the high-pressure pump.
