Abstract
The utility model provides an oxygen mask for a plurality of ofpersons which is comprises an oxygen cylinder, and the oxygen collecting bar is provided with a total stop valve, a filter, and a pressure gauge. The utility model is characterized in that an angular stop valve and an oxygen supply joint are ranged on the oxygen collecting bar, an oxygen discharging pipe joint is also ranged on the oxygen discharging air collecting pipe, an oxygen suction and exhaust tee is installed on the oxygen mask, an oxygen suction and oxygen exhaust two check valves are arranged on the tee, one side of the oxygen suction check valve is connected with a low-pressure oxygen storage bumping bag and a flow controller, and one side of the oxygen exhaust check valve is connected with the oxygen discharging air collecting pipe. The utility model can supply oxygen to many persons simultaneously, the superfluous oxygen is exhausted to outdoors, and the utility model is safe.
Description
This utility model belongs to health care equipment, the oxygen sucking-exhausting device of saying so in more detail.
Existing oxygen inhalation mode adopts the nasal feeding oxygen supply more.Because the oxygen supply of single nostril, oxygen concentration improves little, and unnecessary oxygen drains into indoorly, and fire hazardous has increased unsafe factor.
The purpose of this utility model is in order to solve the problem of above-mentioned existence, a kind of many people oxygen sucking-exhausting device to be provided.It can not have any resistance for many people oxygen uptake simultaneously under normal pressure during oxygen supply, unnecessary oxygen is discharged outdoor, esy to use, safe and reliable by respiratory pressure.
In order to achieve the above object, this utility model comprises medical oxygen cylinder, it is connected on the oxygen bus-bar, total stop valve is housed on the oxygen bus-bar, oxygen filter, high, the middle decompressor of pressing, high, middle pressure pressure table, the oxygen input that it is characterized in that the oxygen bus-bar is arranged with the angle stop valve that can be connected with medical oxygen cylinder, be arranged with the oxygen supply joint that several can be connected with oxygen absorption mask at oxygen bus-bar outfan, the suction and discharge threeway is housed in oxygen absorption mask, the oxygen uptake check valve is housed above, the deoxygenation check valve is connected with flow controller and Low Pressure Oxygen store buffer air bag in oxygen uptake check valve one side, is connected with exhaust expansion bellows in deoxygenation check valve one side, exhaust expansion bellows is sleeved on the oxygen discharging tube joint on the deoxygenation discharge, also is arranged with several oxygen discharging tube joints on the deoxygenation discharge.
In order to prevent to rain, rainwater pours in the deoxygenation discharge, at the end of deoxygenation discharge rainhat is housed.
The effect that Low Pressure Oxygen stores air bag is: in order to solve the difference of vital capacity between the different people, make oxygen therapic patient energy nature, oxygen uptake glibly, and make the pressure of oxygen further cushion blood pressure lowering.Thereby Low Pressure Oxygen store air bag adopt elastic deformation preferably gum elastic make.
Fig. 1 is a layout drawing of the present utility model.
(1) medical oxygen cylinder; (2) oxygen bus-bar; (3) angle stop valve; (4) total stop valve; (5) oxygen filter; (6) high pressure relief device; (7) high-pressure manometer; (8) pressure pressure table in; (9) press decompressor in; (10) oxygen supply joint; (11) flow controller; (12) Low Pressure Oxygen stores air bag; (13) oxygen absorption mask; (14) suction and discharge threeway; (15) oxygen uptake check valve; (16) deoxygenation check valve; (17) exhaust expansion bellows; (18) oxygen discharging tube joint; (19) deoxygenation discharge; (20) rainhat.
Referring to Fig. 1, total stop valve (4) is housed, oxygen filter (5), high, middle pressure decompressor (6), (9), high, middle pressure pressure table (7), (8) on the oxygen bus-bar (2).In order to make many people oxygen uptake simultaneously, oxygen bus-bar (2) be arranged with several angle stop valves (3), oxygen supply joint (10).Angle stop valve (3) is connected with medical oxygen cylinder (1); Oxygen supply joint (10) is connected with oxygen absorption mask (13).Equally, deoxygenation discharge (19) also has several oxygen discharging tube joints (18), and it is connected with exhaust expansion bellows (17).Be connected with suction and discharge threeway (14) at oxygen absorption mask (13) entrance point, oxygen uptake check valve (15) is housed respectively above, deoxygenation check valve (16).When air-breathing, oxygen uptake check valve (15) is opened, and deoxygenation check valve (16) is closed; During aerofluxus, deoxygenation check valve (16) is opened, and oxygen uptake check valve (15) is closed, and unnecessary oxygen and aerofluxus enter deoxygenation discharge (19) along exhaust expansion bellows (17) and be expelled to outdoor.Be connected with flow controller (11), Low Pressure Oxygen store buffer air bag (12) between oxygen uptake check valve (15) and the oxygen supply joint (10).Low Pressure Oxygen store buffer air bag (12) adopts gum elastic to make, and its effect is to make the further blood pressure lowering buffering of oxygen, makes oxygen therapic patient feel nature, smoothness.
Because environmental pollution is on the rise, many healthy people also require oxygen uptake, like this can health invigorating, improve body immunity.Sucted tens minutes oxygen in one day, can feel energetic.This utility model provides this demand for society just, and it has can provide oxygen uptake to many people simultaneously, and unnecessary oxygen is discharged advantages such as outdoor, safe and reliable.
