Abstract
The utility model relates to an anti-suffocation free inhalation valve which comprises the following components: a valve seat, a valve cover, a valve core, a rubber plate, a sealing ring and a spring. The valve seat is internally provided with an air chamber with three ports. A first port of the air chamber in the valve seat is connected with air supplying equipment. A second port of the air chamber in the valve seat is connected with breathing equipment. A third port of the air chamber in the valve seat is connected with a mounting chamber with an opening in the valve seat. The valve seat is also provided with an air way for communicating outer atmosphere with the mounting chamber. The valve cover and the rubber plate are fixedly connected with the opening of the mounting chamber of the valve seat through fasteners. A valve cover chamber body which is formed by the valve cover and the rubber plate is communicated with outer high-pressure control air current. The valve core, the sealing ring and the spring are equipped in a mounting valve. The rubber plate abuts against the top part of the valve core. The valve core abuts against and is sealed on the third port of the valve seat through the sealing ring under an acting force of the rubber plate. One end of the spring abuts against the valve seat, and the other end abuts against the valve core. The structure of the anti-suffocation free inhalation valve prevents suffocation.
Description
Technical field
This is novel to relate to medical respiratory gas valve gear technical field, refers in particular to a kind of anti-free inlet valve that suffocates.
Background technology
At present, the respirator field of medical apparatus and instruments produces oxygen through feeder and to breathe through the air valve patients; Yet; Because the air cavity in the air valve is the enclosed construction that two ends communicate, in case feeder breaks down when not producing oxygen, does not have gas in the air valve; The breathing equipment supply that is connected with air valve not patient's oxygen, can produce the danger that suffocates.In view of this, how designing a kind of novel air valve also can make free air-breathing the becoming of patient that problem to be solved is arranged when feeder breaks down.
Summary of the invention
This novel purpose is exactly that provide to the weak point of prior art a kind of breaks down to prevent to suffocate at feeder and make the free air-breathing anti-free inlet valve that suffocates of patient
For achieving the above object; A kind of anti-free inlet valve that suffocates that this is novel comprises valve seat, valve gap, spool, rubber slab, sealing ring and spring, has the air cavity of threeway in the valve seat; First port of air cavity is connected with air feed equipment in the valve seat; Second port of air cavity is connected with breathing apparatus in the valve seat, and the installation cavity that has opening in the 3rd port of the interior air cavity of valve seat and the valve seat is communicated with, and also has the airway that outside atmosphere is communicated with said installation cavity on the valve seat; Valve gap and rubber slab are fixedly connected on through securing member on the opening of installation cavity of valve seat; Valve gap cavity that valve gap and rubber slab form and outside high voltage control airflow connection; Spool, sealing ring and spring are located in the installation cavity, and rubber slab is pressed on the top of spool, and spool is compressing on the 3rd port that is sealed in valve seat through sealing ring under the rubber slab active force; One end of spring presses on the valve seat, and the other end of spring is pressed on the spool.
High voltage control air-flow in the said valve gap is produced by same said air feed equipment.
Said airway is provided with air filtration sponge and sponge pressing plate, has passage on the sponge pressing plate, and the air filtration sponge is located in the airway, and the sponge pressing plate is installed in the gas outlet end of airway through securing member.
Be connected with joint in the said valve gap cavity, joint is connected with outside high voltage control air-flow.
Blow vent edge on the said valve seat upwards forms chimb, and said sealing ring is pressed on this chimb.
After adopting said structure; This novel elastic force that utilizes rubber slab acts on through the high voltage control air-flow and to form deformation on the rubber slab and depress spool, makes spool that sealing ring is blocked the 3rd port; In case air feed equipment breaks down; Just do not have the high voltage control air-flow in the valve gap air cavity, spool is jack-up under the effect of spring, prevents to suffocate thereby make blow vent be communicated with outside atmosphere.By on can know, this new structure compact, whenever all reliable in function makes patient can freely breathe, and prevents the generation that suffocates.

The specific embodiment
Show like Fig. 1-4; A kind of anti-free inlet valve that suffocates that this is novel; Comprise valve seat 10, valve gap 20, spool 30, rubber slab 40, sealing ring 50 and spring 60; The air cavity that has threeway in the valve seat 10, first port one 1 of air cavity is connected with air feed equipment in the valve seat 10, and second port one 2 of air cavity is connected with breathing apparatus in the valve seat 10; The installation cavity 14 that has opening in the valve seat 10 in the 3rd port one 3 of air cavitys and the valve seat 10 is communicated with, and also has the airway 15 that outside atmosphere is communicated with said installation cavity 14 on the valve seat 10; Valve gap 20 and rubber slab 40 are fixedly connected on through securing member 70 on the opening of installation cavity 14 of valve seat 10; Valve gap 20 and the valve gap cavity 21 of rubber slab 40 formation and the high voltage control airflow connection of outside; Spool 30, sealing ring 50 and spring 60 are located in the installation cavity 14; Rubber slab 40 is pressed on the top of spool 30; Spool 30 is compressing on the 3rd port one 3 that is sealed in valve seat 10 through sealing ring 50 under rubber slab 40 active forces, and an end of spring 60 presses on the valve seat 10, and the other end of spring 60 is pressed on the spool 30.
High voltage control air-flow in the said valve gap 20 is produced by same said air feed equipment.
Said airway 15 is provided with air filtration sponge 81 and sponge pressing plate 82, has passage on the sponge pressing plate 82, and air filtration sponge 81 is located in the airway 15, and sponge pressing plate 82 is installed in the gas outlet end of airway 15 through securing member.
Be connected with joint 90 in the said valve gap cavity 21, joint 90 is connected with outside high voltage control air-flow.
Blow vent edge on the said valve seat 10 upwards forms chimb 16, and said sealing ring 50 is pressed on this chimb 16.
During use; The part of the gases at high pressure that air feed equipment produces gets into first port one 1 of air cavity in the valve seat 10 through air relief valve decompression back; Another part of the gases at high pressure that air feed equipment produces gets into valve gap cavity 21 through joint 90; During operate as normal, the high voltage control air-flows in the valve gap cavity 21 act on and form deformation on the rubber slab 40 and depress spool 30, make spool 30 that sealing ring 50 is blocked the 3rd port one 3; Like this, second port one 2 that the oxygen that enters into first port one 1 of air cavitys in the valve seat 10 just can pass through valve seat 10 interior air cavitys reaches the breathing apparatus patients and has breathed;
When dying in case air feed equipment breaks down; Air cavity and valve gap air cavity 21 all do not have the gas generation in the valve seat 10; At this moment, spool 30 is jack-up under the effect of spring 60, makes the 3rd port one 3 open; Prevent to suffocate thereby be communicated with outside atmosphere through airway 15, ventilation 15 roads here are provided with the effect that air filtration sponge 81 and sponge pressing plate 82 play filtered air.
By on can know, this new structure compact, whenever all reliable in function makes patient can freely breathe, and prevents the generation that suffocates.
