Abstract
The utility model discloses a novel oxygen absorbing mask for operations. An oxygen inlet (2) is positioned on the upper end of a cover body (1), an oxygen outlet (3) is positioned on the lower end of the cover body (1), and a baffle plate (4) is arranged between the oxygen inlet (2) and the oxygen outlet (3). The left side of the cover body (1) is provided with an arc-shaped notch (5). Because the positions of the oxygen inlet, the oxygen outlet, and the arc-shaped notch of a preserved stomach tube are changed, the oxygen absorbing mask can be used more conveniently and reasonably in operations, the operations on chests and abdomens for patients can not be influenced, the patients can feel comfortable, and the concentration of oxygen absorption is enhanced.
Description
This utility model belongs to the novel operation oxygen absorption mask and makes the field.
The air inlet of existing operation oxygen absorption mask is positioned at the face shield lower end, and air vent is positioned at the face shield both sides, during patient's oxygen uptake, oxygen hose is positioned at the breast side, influences the operation of thoracic and abdominal operation and easily pollutes, if reverse use, then cause patient's discomfort, and influence the concentration of oxygen intake.Do not give on the face shield in addition and stay the stomach tube arc notch, it is extremely inconvenient to cause the stomach tube patient to use.
This utility model is at the weak point of above-mentioned existence, a kind of novel operation oxygen absorption mask is provided, air inlet is located at the face shield upper end, air vent is located at the face shield lower end, the stomach tube arc notch is set on the mask body, it is reasonable more, convenient that the operation oxygen absorption mask is used, and improved the inhaled concentration of oxygen and patient's level of comfort.
The purpose of this utility model is achieved in that a kind of novel operation oxygen absorption mask, comprise cover body (1), air inlet (2) and air vent (3), the upper end of cover body (1) is provided with air inlet (2), the lower end is provided with air vent (3), be provided with baffle plate (4) between air inlet (2) and the air vent (3), and baffle plate (4) is fixed on the inboard of cover body (1).The left side of cover body (1) is shaped on arc notch (5).
This utility model is owing to be located at air inlet the upper end of cover body, air vent is located at the lower end of cover body, do not influence the operation of thoracic and abdominal operation and be difficult for polluting, it is convenient, reasonable that it is used in operation, increased baffle design, improved the concentration of oxygen uptake, be shaped on arc notch, used the patient of stomach tube to feel more comfortable in the mask body left side.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a cutaway view of the present utility model.
Embodiment: this utility model is further described below in conjunction with accompanying drawing.
A kind of novel operation oxygen absorption mask, comprise cover body (1), air inlet (2) and air vent (3), the upper end of cover body (1) is provided with air inlet (2), the lower end is provided with air vent (3), be provided with baffle plate (4) between air inlet (2) and the air vent (3), and baffle plate (4) is fixed on the inboard of cover body (1), has prevented that oxygen from directly discharging from air vent (3) when entering from air inlet (2).The left side of cover body (1) is shaped on arc notch (5), makes down pipe stomach patient more convenient when the operation oxygen uptake.
The surgical patient of picked at random 21 routine local block anesthesias adopts identical suction oxygen flow speed (3L/nin), and same patient uses old-fashioned face shield earlier, re-uses the improvement rear mask, respectively with Ohmeda5250RGM monitor monitoring fraction of inspired oxygen (F

2Though change not statistically significant, decline is also arranged, illustrate that the more old-fashioned face shield oxygen supply of improvement rear mask, scavenging action have clear improvement, increased the stomach tube arc notch simultaneously, feel more reasonable, more convenient during use, it is more comfortable that the patient feels.
