The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.It should be noted that hereinafter only the present invention's feature unlike the prior art to be described,, just do not given unnecessary details here for the technical characterictic that can find in the prior art.
The control switching valve that is used for anesthetic machine according to the present invention mainly comprises valve body and is contained in permutator among the valve body.In the present embodiment, for the ease of assembling, permutator is with the form manufacturing of molectron, and it comprises body and bearing.Be introduced below in conjunction with the building block of accompanying drawing control switching valve of the present invention.
At first, schematically show front view, side view, cutaway view and vertical view respectively according to the valve body 8 of control switching valve of the present invention referring to figs. 1 through Fig. 4.This valve body 8 comprises valve pocket 9, air inlet E, manually gas outlet D (i.e. first gas outlet or second gas outlet), machine control gas outlet C, the control QI KOU B and the installing port F that are communicated with anesthetic machine control gas, and this installing port 7 is used for permutator and control device are mounted in the valve pocket 9; Wherein, control QI KOU B, machine control gas outlet C are communicated with the valve pocket 9 of valve body, and do not arrive next face (non through hole), and manual gas outlet D and air inlet E are arranged on the face of valve body 8 and with the valve pocket 9 of valve body 8 and are communicated with.Be understandable that suitable adjustment also can be carried out as required in the position of these air inlets and gas outlet.
Then with reference to Fig. 5 and Fig. 6, schematically show front view and cutaway view respectively according to the body of the gauge tap of control switching valve of the present invention.This body mainly comprises diaphragm seat 2, diaphragm seal pad 1, pull bar 3, spring 4, diaphragm frame 5, sealing valve port pad 6 and O type silica gel sealing ring 7, and wherein, diaphragm seal pad 1, pull bar 3, spring 4 are contained in the diaphragm seat 2.Particularly, pull bar 3 comprises transverse part and bar portion, the outside of transverse part contact diaphragm sealing gasket 1, one end of bar portion is vertically connected at transverse part, and the other end of bar portion is connected in diaphragm frame 5, and spring 4 is set in the bar portion, the one end is against transverse part, and the other end is fixed in diaphragm seat 2; And sealing valve port pad 6 is fixed on the diaphragm frame 5, and diaphragm frame 7 and pull bar 3 are connected by screw thread.Be understandable that O type silica gel sealing ring 7 makes and forms sealing function when being installed to body on the valve body 8, thereby form the valve pocket of sealing on valve body 8.
With reference to Fig. 7 to Fig. 9, show front view, upward view and cutaway view respectively according to the bearing 15 of the gauge tap of control switching valve of the present invention.Two grooves the 12, the 13rd on this bearing 15 are used for fixing sealing ring, thereby form the valve pocket of sealing on valve body 8.
With reference to Figure 10, show installation diagram according to control switching valve of the present invention, wherein, this control switching valve is in manual state.Can notice, the body of permutator and bearing 15 all have been installed in the valve pocket 9, thereby valve pocket 9 is divided into the D ' of first, second portion C ', third part E ' and chamber B ', wherein, the D ' of first is communicated with manual gas outlet D, second portion C ' is communicated with machine control gas outlet C (referring to Fig. 1 and Fig. 3), and third part E ' is communicated with air inlet E, and chamber B ' is communicated with control QI KOU B.And, having first valve port 10 of bearing 15 and second valve port 11 of diaphragm seat 2 among the third part E ', the D ' of first is communicated with third part E ' by first valve port 10, and second portion C ' is communicated with third part E ' by second valve port 11.
Continuation is with reference to Figure 10, when not controlling gas, permutator is under the effect of spring 4, pull bar 3 is to the permutator internal compression, make sealing valve port pad 6 closely contact with second valve port 11 of diaphragm seat 2, thereby third part E ' and second portion C ' are isolated, this moment, third part E ' was communicated with the D ' of first, then air inlet E is communicated with manual gas outlet D, and the The whole control switching valve is in the gas circuit state that gas circuit is switched to manual ventilation.
With reference to Figure 11, in the time of control gas, permutator is under the effect of control gas air pressure, pressure among the chamber B ' increases, diaphragm seal pad 1 produces dilatancy, pushing drawing rod 3 moves up, make sealing valve port pad 6 closely contact with first valve port 10 of bearing 15, thereby third part E ' and the D ' of first are isolated, this moment, third part E ' was communicated with second portion C ' mouthful, then air inlet E is communicated with machine control gas outlet D, and the The whole control switching valve is in the gas circuit state that gas circuit is switched to machine control ventilation.Be understandable that, if the control switching valve is being under the machine control state, the situation that control gas lost efficacy takes place suddenly, and control switching valve then of the present invention will transfer the manual ventilation state to automatically under the effect of the restoring force of spring 4, can continue the control anesthetic machine by manual operation.
Should be noted that, because in operation, exist the gas that enters among the valve pocket B ' that the problem of certain humidity is arranged, this just is easy to cause diaphragm seal pad 1 and the chamber wall of valve pocket B ' that adherent problem takes place, can not normal conversion thereby cause controlling switching valve, therefore on the wall relative of valve pocket B ', be provided with projection 14, thereby solved the problems referred to above, guarantee the safety of operation with diaphragm seal pad 1.
In addition, it should be understood that diaphragm seat 2 and bearing 15 have constituted the supporting construction of permutator jointly, they are made by the metal such as aluminum, correspondingly, diaphragm seal pad 1 and sealing valve port pad 6 are made by the soft elastic material such as silica gel, have therefore guaranteed good being sealed and matched.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All any modifications of being done within the spirit and principles in the present invention, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
