Abstract
The utility model discloses an oxygen inhalation and exhaust separated face mask. The utility model is composed of a mask body 1, an exhaust vent 2, an oxygen transferring joint 3 and an elastic lacing 4, wherein the mask body 1 is made of transparent plastic, the lateral surface of the mask body 1 forms a symmetrical curved surface, and an edge of the mask body is fitted with the face curvature of a mouth and a nose of a human body; the exhaust vent 2 is arranged on both sides of the front wall of the mask body 1; the oxygen transferring joint 3 is arranged on the front-lower part of the mask body 1; the end part of the elastic lacing 4 is fixed on edges at both sides of the front wall of the mask body 1. The connecting position of the oxygen transferring joint 3 and the mask body is provided with an oxygen inhaling control valve 5, and an elastic membrane 6 is glued on the inner wall of the exhaust vent 2. The oxygen inhalation and exhaust separated face mask not only has the advantages that structure is simple and the waste of oxygen can be avoided, but also has the advantage that oxygen inhalation quality and treating effect are enhanced.
Description
Technical field
This utility model relates to a kind of improvement of oxygen absorption mask, and specifically a kind of oxygen uptake and aerofluxus separate type face shield are applicable to hospital ward, hyperbaric oxygen chamber, emergency center etc.
Technical background
At present, used oxygen absorption mask on the hospital clinical is to be made of transparent cover, degree of tightness frenulum, steam vent and oxygen therapy joint, and pure oxygen is supplied with oxygen therapic patient through oxygen catheter by the oxygen therapy joint, and the carbon dioxide that oxygen therapic patient is breathed out is discharged from the steam vent of mouth and nose.The shortcoming of this oxygen absorption mask: the one, when the oxygen therapic patient oxygen uptake, oxygen is easy to flow to OFP from the steam vent of mouth and nose, causes the waste of oxygen; The 2nd, when oxygen therapic patient gave off carbon dioxide, carbon dioxide entered in the oxygen catheter from the oxygen therapy joint again easily, influences the oxygen uptake quality, reduces therapeutic effect.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, can avoid waste of oxygen, can guarantee the oxygen uptake quality again, improve the oxygen uptake and the aerofluxus separate type face shield of therapeutic effect.
For reaching above purpose, the technical scheme that this utility model adopted is: this oxygen uptake and aerofluxus separate type face shield, by cover body, steam vent, the oxygen therapy joint, the degree of tightness frenulum constitutes, cover body is that transparent plastic is made, its cover body side is symmetric curved surface, the face curvature at its edge and human body mouth and nose place matches, steam vent is arranged on cover body antetheca both sides, the place is corresponding with mouth and nose, the oxygen therapy joint is located at the front lower place of cover body, the end of degree of tightness frenulum is fixed on the edge, both sides of cover body antetheca, it is characterized in that establishing the oxygen uptake control valve in the junction of oxygen therapy joint and cover body, elastica on boning on the inwall of steam vent, oxygen therapic patient is adjusted the motion of air-flow by the elastica of oxygen uptake control valve and steam vent, and oxygen uptake is separated with aerofluxus.This utility model is also implemented by following measure: described oxygen uptake control valve, constitute by valve body, retaining platform, valve gap, diaphragm, mandrel, seal washer, the connecting hole of valve body one end and cover body is interference fit, the other end is connected with valve gap with screw thread, establish the retaining platform in valve body, establish diaphragm between retaining platform and valve gap, mandrel one end is connected with diaphragm, the other end inserts in the through hole of valve gap, the valve gap outer end with cure by oxygen therapy joint with being threaded; Described elastica is the annulus bell mouth shape, and the big end outer edge in its mouthful edge is bonded on the inwall of steam vent, and its mouthful can open and close along a little end.When using this utility model, cover body is tied up to the degree of tightness frenulum on the mouth and nose of oxygen therapic patient, when the oxygen therapic patient oxygen uptake, the elastica of steam vent is a closure state, and the diaphragm of oxygen uptake control valve is opened, and enters the intravital oxygen of cover, is sucked by oxygen therapic patient; When oxygen therapic patient gave off carbon dioxide gas, under the effect of air-flow, the diaphragm of oxygen uptake control valve was closed, and the carbon dioxide of exhalation just breaks through the closure state of elastica, and carbon dioxide is discharged, and reached the isolating purpose of oxygen uptake and aerofluxus.
The beneficial effects of the utility model are: compare with the oxygen absorption mask of present use, not only have simple in structure, can avoid the advantage of waste of oxygen, but also have the advantage that improves oxygen uptake quality and therapeutic effect.
