The specific embodiment
The present invention proposes a kind of mixing arrangement that is used for hemodialysis apparatus, by increasing water for dialysis and the mobile distance of dialysis in the mixing arrangement with concentrated solution, increase water for dialysis and dialysis mixer meeting with concentrated solution, thereby the concentrated solution mix homogeneously is used in the water for dialysis and the dialysis of input, be made into the dialysis solution of final working concentration.
In conjunction with Fig. 1, Fig. 2 and shown in Figure 3, mixing arrangement 2 comprises: the urceolus 11 that vertical direction is provided with, and it be cylindric, the loam cake 12 that connects in the upper end of urceolus 11, the lower cover 13 in that the lower end of urceolus 11 connects seals urceolus 11 by loam cake 12, lower cover 13; Be connected the water for dialysis input interface 15 and the dialysis concentrated solution input interface 16 of lower cover 13, on loam cake 12, connect concentrated solution input interface 14; And connect at least two guide shells of setting 18 successively in urceolus 11 inside.
Wherein, guide shell 18 is that bottom lock, a top have opening, cylindric as water tumbler, in the bottom of guide shell 18 at least 1 pod apertures 182 is set, and pod apertures 182 is an inclined hole.
In a preferred embodiment, the bottom of guide shell 18 is near the marginal portion, and concentrating 3 diameters are set is 3 millimeters inclined hole.
In embodiment illustrated in fig. 2, connect successively in urceolus 11 inside 4 guide shells 18 are set, these 4 guide shells 18 are separated into 5 independently cavitys with the inside of urceolus 11.
For convenience, 4 guide shells 18 are designated as first guide shell 1801, second guide shell 1803, the 3rd guide shell 1805 and the 4th guide shell 1807 respectively, and the pod apertures 182 on first guide shell 181, second guide shell 183, the 3rd guide shell 185 and the 4th guide shell 187 is designated as first pod apertures 1802, second pod apertures 1804, the 3rd pod apertures 1806 and the 4th pod apertures 1808 respectively.
Wherein, be the center with the central shaft of guide shell 18, the pod apertures 182 in two two guide shells 18 that are separately positioned on any adjacent connection, about 180 ° of phase contrast, like this, one of them pod apertures 182 is positioned at the oblique upper or oblique below of another pod apertures 182.Such as, first pod apertures 1802 is arranged on the lower left corner of first guide shell 1801, and second pod apertures 1804 is arranged on the lower left corner of second guide shell 1803, and like this, second pod apertures 1804 is positioned at the oblique upper of first pod apertures 1802.Same, concentrated solution input interface 14 is positioned at the oblique below of the 4th pod apertures 1808.
Operation principle of the present invention is as follows:
Water for dialysis is under the pressure of liquid pump, enter the inside of urceolus 11 from water for dialysis input interface 15 with certain flow velocity and flow, dialysis also under the pressure of liquid pump, enters the inside of urceolus 11 with concentrated solution with concentrated solution input interface 16 from dialysis with certain flow velocity and flow; Under the effect of pressure, water for dialysis and dialysis enter first guide shell 1801 with the mixing material of concentrated solution from first pod apertures 1802 of oblique upper, and then enter second guide shell 1803 through second pod apertures 1804 that is positioned at first pod apertures, 1802 oblique uppers, enter the 3rd guide shell 1805 through the 3rd pod apertures 1806 that is positioned at second pod apertures, 1804 oblique uppers, enter the 4th guide shell 1807 through the 4th pod apertures 1808 that is positioned at the 3rd pod apertures 1806 oblique uppers, at last from being positioned at the dialysis solution behind the concentrated solution input interface 14 output mix homogeneously of the 4th pod apertures 1808 on tiltedly.That is, water for dialysis and dialysis are the direction of pressing arrow among Fig. 2 with the flow direction of mixing material in the inside of urceolus 11 of concentrated solution.
To sum up, the mixing arrangement 2 that the present invention proposes is by being provided with a plurality of guide shells 18 that connect successively in urceolus 11 inside, by guide shell 18 urceolus 11 inside are separated into a plurality of independently cavitys, and the entry to mixed solution between the different cavitys is crisscross arranged with about 180 ° of phase contrasts, the mobile distance when thereby recruitment is mixed with dialysis water for dialysis with concentrated solution, increase water for dialysis and dialysis mixer meeting with concentrated solution, thereby the concentrated solution mix homogeneously is used in the water for dialysis and the dialysis of input, be made into the dialysis solution of final working concentration.
In a concrete application example, dialysis makes it to be input to mixing arrangement 2 from dialysing with concentrated solution input interface 16 with the liquid pump of concentrated solution by a monomer capacity big (greater than 0.9ml).Such as, the monomer capacity of liquid pump is 1ml, if dialysis need reach 6ml/ minute with the input flow rate of concentrated solution, then the liquid pump per minute need be input to mixing arrangement 2 with concentrated solution with the dialysis of 6 pumps (chamber), if with each second liquid pump pumped the pump number of dialysing and calculated its operating frequency with concentrated solution, then the operating frequency of liquid pump was 0.1 pump/second.Owing to once the dialysis of larger capacity is imported with concentrated solution with the high capacity liquid pump that mixing arrangement 2 of the present invention is used, therefore need mixing arrangement 2 also to have larger capacity accordingly and hold dialysis and use concentrated solution, provide enough spaces to make itself and water for dialysis mix homogeneously.
Same, general and the monomer capacity of existing mixing arrangement is that the liquid pump of 0.1ml is used, if dialysis need reach 6ml/ minute with the input flow rate of concentrated solution, then the liquid pump per minute need be input to mixing arrangement 2 with concentrated solution with the dialysis of 60 pumps (chamber), therefore, capacity is that the operating frequency of the liquid pump of 0.1ml was 1 pump/second.
Therefore, the present invention can be used by liquid pump big with the monomer capacity, that operating frequency is slower by improving the mixing ability of mixing arrangement, and need not increases extra control circuit into liquid pump.The mixing arrangement that the present invention proposes, for dialysis provides longer mobile distance and incorporation time with concentrated solution and water for dialysis, thereby helping promoting to dialyse uses the uniform mixing of concentrated solution and water for dialysis, obtains meeting the dialysis solution of hybrid standard.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
