Specific embodiment
The specific embodiment of the present invention is described further below in conjunction with the accompanying drawings.
As shown in Figs. 1-5, it is so to realize that the present invention, which is, and the flushing aspirator of the pressure adjustable includes main component 3
And the connecting tube 1 that is connected with main component 3 and work first 2, be structurally characterized in that, be equipped in main component 3 respectively with connecting tube 1 and
The slow storage chambers 301 of first 2 connection of work, be additionally provided on main component 3 the pressure regulation chamber modules that are connected with slow storage chamber 301 and with the tune
Chamber modules cooperation is pressed to adjust the pressure regulating valve component of first 2 operating pressure of work;When operating control, connecting tube 1 and outside
Pump is connected, for that first flushing liquid of 2 conveying with certain pressure intensity of slow storage chamber 301 and work, can also be generated by pumping
Negative pressure by work it is first 2 attract operation in spot;On the one hand due to the design of slow storage chamber 301 so that come from connecting tube 1
Active force will not be directly delivered to work first 2, and then act on wound face, but make after the buffering of too slow storage chamber 301, pressure regulation
Work first 2 has suitable operating pressure;On the other hand, by the cooperation of pressure regulation chamber modules and pressure regulating valve component, in device
Slow storage chamber 301 can be adjusted in tool operating process in real time according to different needs through pressure regulation chamber modules and external gap, and then
Change the pressure adjusted in slow storage chamber 301 so that work first 2 have can flexible modulation operating pressure.
The key structure of the present invention is pressure regulation chamber modules, pressure regulating valve component and pressure regulation chamber modules and pressure regulator valve
The locations of structures design of door component, in the specific implementation, one of the pressure regulation chamber modules implements structure such as Fig. 2 and Fig. 3 institutes
Show, it includes several regulator holes 303 being located on main component 3, is communicated between regulator hole 303 and slow storage chamber 301 and pressure regulation
The pressure regulating cavity 302 of valve member cooperation;So connected due to delaying storage chamber 301 by pressure regulating cavity 302 through regulator hole 303 with outside,
As long as the gap size that control pressure regulating cavity 302 is connected with outside, it is possible to flexibly change in the case of 1 invariablenes pressure of liquid of connecting tube
The pressure of slow storage chamber 301, and then adjust the operating pressure of work first 2;The implementation structure of certain pressure regulation chamber modules not office
Be limited to this, in actual design, if the pressure regulation chamber modules can be connected between slow storage chamber 301 and outside, and with tune
The cooperation of pressure valve component changes slow storage chamber 301 and the size of external communication gap.
In order to improve the convenience for controlling to adjust operation, the present invention, which is also optimized the structure of pressure regulating valve component, to be set
Meter particularly may be divided into following three kinds of implementation structure;
The pressure regulating valve component includes the control valve 4 coordinated with pressure regulating cavity 302, and control valve 4 is fixedly connected with one
The slide-and-guide bar 5 set along 3 length direction of main component;Slide-and-guide bar 5 is arranged one away from one end periphery of control valve 4 and leads
To set 8,5 periphery of slide-and-guide bar between guide sleeve 8 and control valve 4 is also surrounded with spring 6;As long as so mobile guide set
8, it is made to be moved along slide-and-guide bar 5 to control valve 4, guide sleeve 8 can compress spring 6, and the elastic force using spring 6 is compeled
Control valve 4 is made constantly to tie up pressure regulating cavity 302, and then reduces the gap that regulator hole 303 is connected with slow storage chamber 301, is thus changed
The pressure of slow storage chamber 301 is become.
Based on said structure, in one embodiment of the pressure regulating valve component, it include for drive guide sleeve 8 along
The slidable adjustment set 7 that slide-and-guide bar 5 slides;Slidable adjustment set 7 and the guide groove set along 3 length direction of main component
305 are slidably connected, and several are additionally provided on main component 3 and fixes the gear 304 that slidable adjustment covers 7 positions, such as Fig. 4 and Fig. 5 institutes
Show;It is so moved by 7 drive guide sleeve 8 of slidable adjustment set, slidable adjustment set 7 is located at outside main component 3, operation movement
It is more convenient, slidable adjustment set 7 is fixed with screens due to being provided with multiple gears 304 on main component 3, slidable adjustment covers 7 edges
It after guide groove 305 slides into suitable position and is secured on corresponding gear 304, it is simple in structure, it is easy to control, rationally
The quantity of gear 304 is set to be remarkably improved the precision of pressure adjusting.
Certainly, in order to preferably meet the needs of digitlization, automation control, the pressure regulating valve component can also use
Second of embodiment, specifically as shown in fig. 6, the pressure regulating valve component further includes to drive guide sleeve 8 along slide-and-guide bar 5
The screw 10 of slip, one end of the screw 10 are connected with 8 screw drive of guide sleeve, and the output shaft transmission of the other end and motor 11 connects
It connects;As long as so control the rotation of motor 11, it is possible to the flexible of guide sleeve 8 is driven through screw 10, and then according to above-mentioned principle
Change the pressure of slow storage chamber 301.In order to improve the closure of instrument and maintainability, in above-mentioned two embodiment, the main body
One end that part 3 deviates from work first 2 is also associated with dismountable tail-hood 9.
In order to be further simplified structure, pressure regulating valve component of the present invention can also use the third embodiment, described such as Fig. 7
Shown, the main component 3 is connected with the screwed pipe 12 with the cooperation of 3 inner thread of main component away from one end of work first 2;The screw thread
Pipe 12 is equipped with gear item 1201, other end closing close to one end of guide sleeve 8, and is also associated with driving its rotation on screwed pipe 12
Spiral arm 1202;As long as by 1202 rotated threaded tubular 12 of spiral arm, under helicitic texture cooperation, screwed pipe 12 will be along main body
3 inner wall of part stretches, and then using gear item 1201 guide sleeve 8 is promoted to move, and changes the pressure of slow storage chamber 301 according to above-mentioned principle
By force.
By taking flushing process as an example, when practical operation designs, the connector of connecting tube 1 is general female Luer, product
By the way that flushing liquid is injected into slow storage chamber 301 into connecting tube 1, promoted using slidable adjustment set 7, screw 10 or screwed pipe 12
Guide sleeve 8 moves, and when guide sleeve 8 gets over forward compression springs 6, obtained pressure will be bigger in slow storage chamber 301, so that
First 2 hydraulic pressure gone out must be worked also can be bigger, conversely, the water that work first 2 is gone out will become smaller, so by adjusting spring
The pressure of 6 pairs of control valves 4 adjusts the flushing pressure of work first 2.The flushing aspirator is simple in structure, operates conveniently,
Meet the needs of medical staff by different flushing pressures, solve normal developing aspirator pressure it is unadjustable or adjust
Press the problems such as cumbersome.
