Abstract
The utility model provides an oxygen bag pressure-limiting protector, which includes a housing, an oxygen incoming channel, an aeration channel, a valve core, a spring, an adjusting nut and a pressure-limiting valve, wherein the oxygen incoming channel is communicated with a hollow cavity in the housing, the aeration channel is communicated with the oxygen incoming channel, one end of the pressure-limiting oxygen outlet valve is communicated with the hollow cavity in the housing, the other end is communicated with the aeration channel, the valve core is arranged in the hollow cavity of the housing and is connected with the adjusting nut through the spring. The elastic force of the spring can be controlled through the adjusting nut, so as to preset the pressure when an oxygen bag is full of oxygen; and when the oxygen bag is full of oxygen, the pressure-limiting outlet valve is closed to stop aeration, and the pressure in the oxygen bag can keep constant. The protector has a simple structure, the manufacturing cost is low, the protector is convenient to use, the labor intensity can be greatly reduced, the oxygen is saved and the service life of the oxygen bag product can be prolonged.
Description
Technical field
This utility model relates to a kind of oxygen bag voltage-limiting protector, belongs to technical field of medical instruments.
Background technology
People by carry oxygen bag can be as required oxygen intake easily whenever and wherever possible.At present when inflating to oxygen bag, it generally is the high pressure gas outlet that oxygen bag directly is communicated with high-pressure oxygen cylinder or central oxygen supply plant, sensation and experience with the people are finished inflation, for avoiding the high pressure oxygen portable oxygen airbag that rises brokenly, after being full of, medical personnel's " sensation " oxygen bag should in time disconnect source of the gas.So not only make operator spirit high-pressure, and easily cause the interior oxygen pressure of each oxygen bag inconsistent, the bag internal oxygen atmospheric pressure is crossed low can influence the use, hypertonia easily causes the oxygen bag blast of rising brokenly, not only increase hospital's operating cost and patient's medical expense, the fragment that oxygen bag rises brokenly after exploding also can cause medical personnel's eyes or other personal injuries possibility, causes that unnecessary personal injury and doctor-patient dispute take place, and brings negative effect for hospital, medical worker and patient.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, can keep the constant oxygen bag voltage-limiting protector of oxygen bag internal gas pressure automatically.
In order to achieve the above object, the technical scheme that this utility model adopted is: comprise housing, oxygen admission passage, filling channel, spool, spring, adjusting nut and pressure limiting valve, wherein the oxygen admission passage is connected with the housing internal cavity, filling channel is connected with the oxygen admission passage, pressure limiting air outlet valve one end is connected with the housing internal cavity, and the other end is positioned at the housing internal cavity with filling channel connection, spool and links to each other with adjusting nut by spring.
As further improvement of the utility model, the end near the oxygen admission passage on spool is provided with sealing ring.
Owing to adopted said structure, air pressure in the time of can preestablishing oxygen bag by the elastic force of adjusting nut control spring and be full of, when oxygen bag is full of gas, the oxygen bag internal pressure reaches setting value time limit extrusion air valve and closes, oxygen bag can not be inflated again, thereby guarantee that the oxygen bag internal gas pressure is constant, it is low or too high to avoid a bag internal pressure to cross.This device is simple in structure, cheap for manufacturing cost, easy to use, can stop to improve Labor Safety, reduce labor intensity because of misoperation causes the injury that the oxygen bag blast causes oxygenation operation medical worker's positions such as personal injury, especially eyes, also can improve the quality of oxygen bag product, prolong oxygen bag service life, reduce medical treatment cost, avoid unnecessary doctor-patient dispute.
Description of drawings
Fig. 1 is the longitudinal profile sketch map of a kind of embodiment of this utility model oxygen bag voltage-limiting protector.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1; oxygen bag voltage-limiting protector of the present utility model comprises housing 1, oxygen admission passage 2, filling channel 3, spool 4, spring 5, adjusting nut 6 and pressure limiting air outlet valve 7; wherein oxygen admission passage 2 is connected with housing 1 internal cavity; filling channel 3 is connected with oxygen admission passage 2; pressure limiting air outlet valve 7 one ends are connected with housing 1 internal cavity, and the other end is communicated with filling channel 3, spool 4 is positioned at housing 1 internal cavity and also links to each other with adjusting nut 6 by spring 5.During use, the air pressure in the time of can preestablishing oxygen bag by the elastic force of adjusting nut 6 control springs 5 and be full of, when oxygen bag was full of gas, oxygen just made pressure limiting air outlet valve 7 close and no longer inflation, thereby can keep the oxygen bag internal gas pressure constant.On spool 4, be provided with sealing ring 8, can strengthen airtight performance of the present utility model, prevent oxygen leakage and cause waste near an end of oxygen admission passage 2.This device is simple in structure, cheap for manufacturing cost, easy to use, can stop to improve Labor Safety, reduce labor intensity because of misoperation causes the injury that the oxygen bag blast causes oxygenation operation medical worker's positions such as personal injury, especially eyes, also can improve the quality of oxygen bag product, prolong oxygen bag service life, reduce medical treatment cost, avoid unnecessary doctor-patient dispute.
Certainly, this utility model is not limited to the scope of embodiment, and for example, adjusting nut 6 also can adopt alignment pin; Spring 5 also can adopt shell fragment or other can produce the parts of elastic force.So long as can realize the technical solution of the utility model as previously mentioned, reach its technique effect, all within this utility model protection domain.
