Atomization dosing device integrated in breathing machine pipeline

Abstract

The invention discloses an atomization dosing device integrated in a breathing machine pipeline, and relates to the technical field of medical instruments. The device comprises a mixed gas supply pipeand a medicine supply pipe; fixing plates are fixed in the mixed gas supply pipe side by side; an adjusting notch is formed in the side wall of the mixed gas supply pipe; an adjusting plate is rotationally connected between the two fixing plates through a connecting column; vent holes are circumferentially arrayed in the side surfaces of the two fixed plates; the connecting column is provided with an atomization hole, and the two ends of the atomization hole penetrate through the fixing plates.; the medicine supply pipe corresponds to the atomization hole in position; adjusting holes corresponding to the vent holes are formed in the side surface of the adjusting plate; and shifting rods in clearance fit with the adjusting notches are fixed to the peripheral side face of the adjusting plate. The adjusting plate is rotated to adjust the gas amount, so that the particle size of atomized liquid drops is adjusted, and the purpose that the particle size of the atomized liquid drops is uniform and controllable is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an atomized drug delivery device integrated in a ventilator pipeline. Background technique [0002] Medical ventilators can effectively replace the function of spontaneous ventilation, and have been widely used in respiratory failure caused by various reasons, anesthesia breathing management during major surgery, respiratory support treatment and emergency resuscitation, occupying a very important position in the field of modern medicine. It is a vital medical device that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. [0003] In the prior art, medical ventilators generally only provide the function of oxygen supply, which lacks adaptability to patients who need atomized drug administration while inhaling oxygen. It is troublesome, and it will prolong the treatment time, which is not good for the patient's recovery...
