Description
The present invention relates to medium is input to the medical apparatus and instruments of human body, say it is a kind of filter for transfusion in detail.
We know, during clinical infusion liquid, for preventing the harm of antibacterial, particulate matter etc., cause adverse reactions of patients, are provided with filter for transfusion on transfusion device.Existing filter for transfusion, a kind of is to be provided with feed tube on upper shell, lower house is provided with drain pipe, is provided with filter membrane between upper shell and the lower house, forms feed liquor cavity and fluid cavity, relies on the pressure reduction perpendicular flow of feed liquor cavity and fluid cavity liquid.Another kind is to be provided with filter membrane between left shell and right shell body, forms feed liquor cavity and fluid cavity, and the housing top is provided with feed tube, and the housing below is provided with drain pipe, relies on the pressure reduction perpendicular flow of feed liquor cavity and fluid cavity liquid.Above-mentioned filter for transfusion owing to rely on the pressure reduction perpendicular flow of feed liquor cavity and fluid cavity liquid, easily deposits antibacterial and particulate matter etc. on the filter membrane, stop up the filtering holes of filter membrane, and poor filtration effect does not reach the limit flow requirement, and service life is short.
Purpose of the present invention provides difficult deposition antibacterial and particulate matter etc. on a kind of filter membrane, and the filtering holes of filter membrane is difficult for stopping up, good filtration effect, the traffic requirement that can reach capacity, the filter for transfusion of long service life.
For achieving the above object, the present invention adopts following scheme to realize:
Be provided with filter membrane between left shell and the right shell body, form feed liquor cavity and fluid cavity, the housing top is provided with feed tube, and the housing below is provided with drain pipe, and its primary structure characteristics are to be provided with flow-guiding channel in the feed liquor cavity.
The present invention is owing to be provided with flow-guiding channel in the feed liquor cavity, and flow-guiding channel can change liquid perpendicular flow direction, makes liquid form tangent line stream or vortex flow, from admission chamber direction of flow fluid cavity; Because liquid tangent line or vortex from admission chamber direction of flow fluid cavity, are difficult for deposition antibacterial and particulate matter etc. on the filter membrane, the filtering holes of filter membrane is difficult for stopping up good filtration effect, the traffic requirement that can reach capacity, long service life; Because be provided with flow-guiding channel in the feed liquor cavity, flow-guiding channel can support filter membrane, increase and filter film strength, filter membrane is cracky not, long service life.The present invention is applicable to clinical infusion liquid.

Figure 11 also is the D-D cutaway view of Fig. 7, is the sketch map of a kind of embodiment of flow-guiding channel in the feed liquor cavity;
Below in conjunction with accompanying drawing, the present invention is elaborated.
From Fig. 1, Fig. 2, Fig. 3 as can be seen, be provided with filter membrane 4 between left shell 3 and the right shell body 2, form feed liquor cavity 5 and fluid cavity 6, the housing top is provided with feed tube 1, the housing below is provided with drain pipe 7, feed tube 1 and drain pipe 7 can be arranged on left shell 3 or the right shell body 2, also can be separately positioned on left shell 3 and the right shell body 2, as can be seen from the figure are arranged on the left shell 3.Feed tube 1 is connected with feed liquor cavity 5, and drain pipe 7 is connected with fluid cavity 6.Be provided with flow-guiding channel 9 in the feed liquor cavity 5, flow-guiding channel 9 is annular flow-guiding channels.Liquid enters feed liquor cavity 5 through feed tube 1, and vortex flow under the effect of annular flow-guiding channel 9 through entering fluid cavity 6 after filter membrane 4 filtrations, flows out through drain pipe 7.Because the liquid tangent line enters feed liquor cavity 5, vortex flows to fluid cavity 6 from feed liquor cavity 5, is difficult for deposition antibacterial and particulate matter etc. on the filter membrane 4, and the filtering holes of filter membrane 4 is difficult for stopping up good filtration effect, the traffic requirement that can reach capacity, long service life; Flow-guiding channel 9 can also support filter membrane 4, increases the intensity of filter membrane 4, and filter membrane 4 is cracky not, increases service life.Be provided with supporting seat 8 in the fluid cavity 6, supporting seat 8 matches with flow-guiding channel 9, clamping, support filter membrane 4, filter membrane 4 is cracky not, increases service life, can also be liquid guide flow, supporting seat 8 can be made the supporting seat identical with flow-guiding channel 9, and interchangeability is good.
As can be seen from Figure 4, flow-guiding channel 9 is even cloth multilamellar arc flow-guiding channels, can make liquid form vortex flow; As can be seen from Figure 5, flow-guiding channel 9 is single head spiral stream guidance passages, can make liquid form vortex flow; As can be seen from Figure 6, flow-guiding channel 9 is even radial flow-guiding channels of cloth, can make liquid form tangent line and flow, and other repeat no more as above-mentioned.
From Fig. 7, Fig. 8, Fig. 9 as can be seen, be provided with filter membrane 4 between left shell 3 and the right shell body 2, form feed liquor cavity 5 and fluid cavity 6, the housing top is provided with feed tube 1, the housing below is provided with drain pipe 7, feed tube 1 and drain pipe 7 can be arranged on left shell 3 or the right shell body 2, also can be separately positioned on left shell 3 and the right shell body 2, as can be seen from the figure are to be separately positioned on left shell 3 and the right shell body 2.Feed tube 1 is connected with feed liquor cavity 5, and drain pipe 7 is connected with fluid cavity 6.Be provided with flow-guiding channel 9 in the feed liquor cavity 5, flow-guiding channel 9 is flow-guiding channels that even cloth is parallel to each other.Liquid enters feed liquor cavity 5 through feed tube 1, and is moving at the effect incision linear flow of the flow-guiding channel 9 that is parallel to each other, and enters fluid cavity 6 after filtering through filter membrane 4, flows out through drain pipe 7.Because the liquid tangent line flows to fluid cavity 6 from feed liquor cavity 5, be difficult for deposition antibacterial and particulate matter etc. on the filter membrane 4, the filtering holes of filter membrane 4 is difficult for stopping up good filtration effect, the traffic requirement that can reach capacity, long service life; Flow-guiding channel 9 can also support filter membrane 4, increases the intensity of filter membrane 4, and filter membrane 4 is cracky not, increases service life.Be provided with supporting seat 8 in the fluid cavity 6, supporting seat 8 matches with flow-guiding channel 9, clamping, support filter membrane 4, filter membrane 4 is cracky not, increases service life, can also be liquid guide flow, supporting seat 8 can be made the supporting seat identical with flow-guiding channel 9, and interchangeability is good.
As can be seen from Figure 10, flow-guiding channel 9 is multi-head spiral flow-guiding channels, can make liquid form vortex flow; As can be seen from Figure 11, flow-guiding channel 9 is even cloth multilamellar arc flow-guiding channels, can make liquid form vortex flow, and other repeat no more as above-mentioned.
