Abstract
The utility model relates to the technical field of medical breathing air valve devices, in particular to a high-efficiency negative pressure suction air valve. The high-efficiency negative pressure suction air valve comprises a valve seat and a venturi valve core, wherein a three-way air cavity is formed in the valve seat; an air inlet port of a ventilation hole of the venturi valve core is larger than an air outlet port; during assembly, the venturi valve core is inserted and sealed in the air inlet port of the air cavity in the valve seat; an air suction port on the valve seat is communicated with external air and is positioned in a negative pressure region formed by the air outlet port of the venturi valve corev; and the air outlet port of the valve seat is connected with external breathing equipment. After the structure is adopted, the high-efficiency negative pressure suction air valve has the characteristics of automatically sucking air to dilute oxygen and replenish the air.
Description
Technical field
This is novel to relate to medical respiratory gas valve gear technical field, refers in particular to a kind of efficient negative pressure and sucks air cock.
Background technology
At present, in the respirator field of medical apparatus and instruments, produce oxygen through feeder and to breathe through the air valve patients; Yet; Existing air valve mostly is two logical structures of sealing, and supply is limited because the concentration of oxygen that feeder produces is higher, the oxygen of high concentration need and the atmosphere mixed diluting after be supplied to patient respiration; Therefore, how to improve existing air valve and realize that above-mentioned functions becomes problem to be solved is arranged.
Summary of the invention
This novel purpose is exactly that provide to the weak point of prior art a kind of can suck the efficient negative pressure suction air cock that atmosphere comes dilution oxygen concentration and replenishes tolerance automatically.
For achieving the above object, a kind of efficient negative pressure sucks air cock, comprises valve seat and venturi spool; The air cavity that has threeway in the valve seat, the air inlet port of the passage of the venturi spool port of giving vent to anger is big, during assembling; The venturi spool is pegged graft and is sealed in the air inlet port of air cavity in the valve seat; Suction port on the valve seat communicates with outside atmosphere, and the suction port on the valve seat is positioned at venturi spool outlet side interruption-forming negative pressure region, and the port of giving vent to anger of valve seat is connected with outside breathing apparatus.
Be plugged with the suction gas connection on the air inlet port of the passage of said venturi spool.
Said venturi spool is through close the joining of inlet end implication of air inlet sealing ring and valve seat.
On the port of giving vent to anger of said valve seat through the sealing ring of the giving vent to anger gas outlet joint that has been tightly connected.
The air inlet port of said venturi spool is connected with the air source inlet joint.
After adopting said structure; This novel Venturi effect of utilizing the venturi spool; Be that the position that highly compressed air-flow bumps out can form negative pressure; This negative pressure will suck extraneous air automatically from the suction port on the valve seat, and air has diluted the high pressure concentration of oxygen and mixed the back port of giving vent to anger from valve seat with it and exported to the breathing of breathing apparatus patients.By on can know, the utlity model has and can suck the characteristics that atmosphere comes dilution oxygen concentration and replenishes tolerance automatically.

Fig. 3 is this novel solid structural representation.
The specific embodiment
Show like Fig. 1-3; This novel a kind of efficient negative pressure sucks air cock, comprises valve seat 10 and venturi spool 20, has the air cavity of threeway in the valve seat 10; The air inlet port of the passage 21 of venturi spool 20 port of giving vent to anger is big; During assembling, venturi spool 20 is pegged graft and is sealed in the air inlet port 11 of air cavity in the valve seat 10, and the suction port 13 on the valve seat 10 communicates with outside atmosphere; And the suction port on the valve seat 10 is positioned at venturi spool 20 outlet side interruption-forming negative pressure regions, and the port 12 of giving vent to anger of valve seat 10 is connected with outside breathing apparatus.
Be plugged with on the said suction port 13 and suck gas connection 70.
Said venturi spool 20 is through inlet end implication close join of air inlet sealing ring 40 with valve seat 10.
On the port of giving vent to anger of said valve seat 10 through the sealing ring 50 of the giving vent to anger gas outlet joint 60 that has been tightly connected.
The air inlet port of said venturi spool 20 is connected with air source inlet joint 30.
During use; After the high pressure high-concentration oxygen of air feed equipment generation gets into the passage 21 of venturi spools 20 from air source inlet joint 30; Highly compressed oxygen is from port when ejection of giving vent to anger of venturi spool 20; Space on every side forms negative pressure region, and this negative pressure sucks extraneous air from sucking gas connection 70, and air has diluted the high pressure concentration of oxygen and mixed the back with it and exported to the breathing of breathing apparatus patients from the gas outlet joint 60 on the port 12 of giving vent to anger of valve seat 10.Like this, can replenish the deficiency that air feed equipment produces tolerance on the one hand, can dilution oxygen concentration be convenient to patient respiration on the other hand.
By on can know, the utlity model has and can suck the characteristics that atmosphere comes dilution oxygen concentration and replenishes tolerance automatically.
