The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing: the present embodiment is implemented under take technical solution of the present invention as prerequisite, has provided detailed embodiment, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, a kind of ophthalmology ultrasonic emulsification instrument flow regulator that the present embodiment is related, comprise: ultrasonic emulsification instrument suction pipeline inflow segment 1, Medical tee joint valve 2, the pipeline 3 identical with ultrasonic emulsification instrument suction pipeline internal diameter, the inflow pipeline 4 that connects the hard liquid-collecting box, the outflow pipeline 5 that connects the hard liquid-collecting box, hard liquid-collecting box 6, filtering net 7, Flow-rate adjustment element 9, the ultrasonic emulsification instrument suction pipeline flows out section 10 and threeway jointing 11, the first port of described ultrasonic emulsification instrument suction pipeline inflow segment 1 and Medical tee joint valve 2 is connected, an end that connects the inflow pipeline 4 of hard liquid-collecting box is connected with the second port of Medical tee joint valve 2, the other end that connects the inflow pipeline 4 of hard liquid-collecting box is connected with the entrance of hard liquid-collecting box 6, one end of the pipeline 3 identical with ultrasonic emulsification instrument suction pipeline internal diameter is connected with the 3rd port of Medical tee joint valve 2, the other end of the pipeline 3 identical with ultrasonic emulsification instrument suction pipeline internal diameter is connected with the first port of threeway jointing 11, an end that connects the outflow pipeline 5 of hard liquid-collecting box is connected with the outlet of hard liquid-collecting box 6, the other end that connects the outflow pipeline 5 of hard liquid-collecting box is connected with the second port of threeway jointing 11, the 3rd port of threeway jointing 11 flows out section 10 with the ultrasonic emulsification instrument suction pipeline and is connected, Flow-rate adjustment element 9 is serially connected on the outflow pipeline 5 that connects the hard liquid-collecting box, is provided with filtering net 7 in the hard liquid-collecting box 6.
Further, also comprise valve 8, described valve 8 is installed in the bottom of hard liquid-collecting box 6 and is connected with hard liquid-collecting box 6 inside.
As shown in Figures 2 and 3, described Flow-rate adjustment original paper 9 is comprised of housing 9-1 and plate object 9-2, and described plate object 9-2 is fixed in the housing 9-1, and plate object 9-2 is provided with Flow-rate adjustment micropore 9-3.
The interior diameter of described Flow-rate adjustment micropore 9-3 is set in 0.26mm to the 0.001mm scope.The needs that can adapt to so different ultrasonic emulsification instruments.
Work process: when ultrasonic emulsification instrument is in normal operating conditions, Medical tee joint valve 2 will connect the inflow pipeline 4 of hard liquid-collecting box and close, liquid can normally flow to Medical tee joint valve 2 by ultrasonic emulsification instrument vacuum suction pipeline (flowing into end), flow to the pipeline 3 identical with ultrasonic emulsification instrument suction pipeline internal diameter by Medical tee joint valve 2, by the vacuum suction pipeline outflow section 10 of the pipeline 3 identical with ultrasonic emulsification instrument suction pipeline internal diameter by threeway jointing 11 normal flow direction ultrasonic emulsification instruments, this moment, this flow regulator was not had an effect.When needs reduce the fluid flow of excusing from death emulsification instrument temporarily, close by the pipeline 3 that Medical tee joint valve 2 is identical with ultrasonic emulsification instrument suction pipeline internal diameter, the inflow pipeline 4 that connects the hard liquid-collecting box is opened, the flow direction of this moment is for flowing to Medical tee joint valve 2 by ultrasonic emulsification instrument vacuum suction pipeline (flowing into end) 1, flow to the inflow pipeline 4 that connects the hard liquid-collecting box by Medical tee joint valve 2, flow to hard liquid-collecting box 6 by the inflow pipeline 4 that connects the hard liquid-collecting box, flow to Flow-rate adjustment element 9 by hard liquid-collecting box 6, flow to threeway jointing 11 by Flow-rate adjustment element 9 by the outflow pipeline 5 that connects the hard liquid-collecting box, flow to ultrasonic emulsification instrument vacuum suction pipeline (outflow end) 10 by threeway jointing 11, this moment is because the aperture of Flow-rate adjustment element is far smaller than the internal diameter of ultrasonic emulsification instrument vacuum suction pipeline, so the fluid flow in the whole pipeline be far smaller than the ultrasonic emulsification instrument normal operating conditions flow (concrete flow by ultrasonic emulsification instrument at that time negative pressure value and the aperture of Flow-rate adjustment element jointly determine), therefore can be the duty that ultrasonic emulsification instrument provides a kind of interim low discharge.
The above; only be the better specific embodiment of the present invention; these specific embodiment all are based on the different implementations under the general idea of the present invention; and protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
