Expectoration-aid mask for noninvasive ventilator use

Abstract

The invention relates to the technical field of auxiliary medical equipment, and discloses an expectoration-aid mask for noninvasive ventilator use. The expectoration-aid mask for noninvasive ventilator use comprises a mask body to be fitted to the mouth and the nose; an air inlet is arranged on the mask body; an air inlet pipe is integrally connected with the air inlet; headbands used for fixingthe mask body are connected with edges of the mask body via buckles; a plurality of vent holes are formed on the air inlet pipe; and the air inlet pipe is furhter arranged with a control valve used for adjusting air flow rate. The expectoration-aid mask for noninvasive ventilator use further comprises a three-way pipe joint; one end of the three-way pipe joint is connected with an outer end of theair inlet pipe while the other two ends of the three-way pipe joint are correspondingly connected with an air supply pipe and an atomization pipe; a pipe cover can be arranged, at the end connected with the atomization pipe, on the three-way pipe joint in a detachable way; an expectoration opening is further arranged, under the air inlet, on the mask body; a sputum suction tube is connected withthe expectoration opening in a detachable way; and a sealing cap is arranged on the expectoration opening in a detachable way. During operation of the expectoration-aid mask for noninvasive ventilatoruse, the mask is not required to be removed when expectoration is performed, so that, removal of sputum is facilitated; moreover, the sputum is sucked by the sputum suction tube, so that, the expectoration-aid mask for noninvasive ventilator use is convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an auxiliary expectoration mask for a non-invasive ventilator. Background technique [0002] Non-invasive ventilators are clinically used to treat sleep apnea syndrome and mild to moderate respiratory failure and other related diseases. Patients suffering from these diseases need positive pressure air supply, and often suffer from lung infections, resulting in sputum. Some non-invasive ventilator masks have only one air inlet. When patients need to expel sputum, they need to take off the mask to suck and expel sputum. [0003] How to make the existing non-invasive ventilator mask do not need to take off the mask when the patient expels sputum, and at the same time facilitate the discharge of sputum is a potential demand of doctors, nurses and patients. Contents of the invention [0004] The invention provides an auxiliary sputum removal mask for a noninvasi...
