Dialyzer

专利摘要:
An apparatus for diffusing matter between a first and second fluid is provided and includes a plurality of spacer plates and a plurality of pairs of semipermeable membranes arranged in a stacked configuration. The spacer plates and semipermeable membranes each include first and second openings which, in the stacked configuration, form first and second vertical flow passages for the first and second fluids, respectively. In addition, the spacer plates include grooves formed in the upper and lower surfaces thereof so that in the stacked configuration, the grooves cooperate to form first horizontal flow passages between the membranes and the spacer plates which are connected to the first vertical flow passage. The pairs of semipermeable membranes are disposed within the grooves to form second horizontal flow passages between the membranes which are connected to the second vertical flow passage, with the second horizontal flow passages being disposed within the first horizontal flow passages.

(5) DIALYZER
The invention relates to medical technology and is intended to diffuse the flow of matter between two heavy fluids through semipermeable membranes.
A dialyzer is known, which contains support plates with flanges sealed around the perimeter, through holes at the ends, grooves between two holes, collectors formed as a system of channels symmetrically arranged about the plate axis, and channels for supplying and draining fluid to through holes 1 .15
However, the known dialyzer does not provide a sufficiently complete and rapid return of blood to the patient.
The purpose of the invention is to provide 20 more complete quick return of blood to the patient.
The goal is achieved by the fact that the collectors are V-shaped, and the supply and discharge channels to 25
one of the through holes are located at an angle to one another.
Besides,. V-shaped collectors in the central part have an arcuate recess located concentrically through the through hole.
Fig. 1 shows a support plate, top view; in fig. 2 - the same, bottom view; in fig. 3 shows section A-A in FIG. 2; in fig. A - section BB in FIG. 2; in fig. 5 is a section bb In figure 2; in fig. 6 is a section of GGD in FIG. in fig. 7 shows a DD-D in FIG. 1; FIG. 8 - section EE of FIG. 1; in fig. 9 zoomed area of the surface of the support plate; in fig. 10 is a section of an LF in FIG. 2; in fig. 11 - section 3-3 in FIG. 2; in fig. 12 - dialyzer, top view; in fig. 13 the same, side view; in fig. 1 is a section view of AND-I in FIG. 13.
The dialyzer contains the head part 1 and the bottom part 2 with built-in intermediate support plates 3 and

placed between the support plates of the membranes k. The support plates 3 are alternately turned 180 in their own plane o. This being depicted in FIG. 1, the surface is always adjacent to the same surface, for example, shown in FIG. Similarly, the plane according to the left suit (figure 2) or the right part (figure 1) are adjacent to one another. Thereby (DLP) blood supply channels 5 are formed in case of using the device as an artificial kidney between the notches 6.
Similarly, blood supply channels 8 are formed between membranes k in front of the notches 7 (Fig. 11). This is also done over the entire surface of the support plate, i.e. blood channels are formed exactly in front of each lowered portion of this surface. The channels 5 for supplying blood are formed inside the V-shaped zone, which passes into the through-hole 9. The through-holes 9 and 10 are located at the ends of the support plates 3 on the bisectrix formed by the notches 6 of the V-shaped zone. Along the same bisector, there are other notches 11 designed to facilitate blood flow. An arcuate loop 12 in front of the through hole 10, concentric to this hole, serves for this purpose. Because the arcuate notch 12 is completely through, it also facilitates the distribution of cleaning fluid.
On the periphery of the support plate 3, a seal 13 (FIGS. 1 and 3) is inserted into a recess 14, the tight connection of which to the V-shaped zone reduces the remaining blood when the device is emptied.
The through hole 9 in the support plates 3 (FIG. 3) is surrounded by seals 15 and 16, which serve to press the membrane tightly against the distributor.
In the circular portion 17, a working surface is highlighted. The support plate (Fig. 9), consisting of a zigzag pattern 22, .4
elevations 18 with channels 19 arranged between them. The ends of the support plates are connected to the working surface itself only peripherally by means of ribs 20 (Fig. 7). Due to the fact that the edge of the plate 21 is raised, the shape of the bowl is formed, facilitating and membranes one upon the other.
The through hole 10, as well as the through hole 9, is surrounded by a seal 22 intended to press two adjacent membranes against the annular surface 23. Similarly, the adjacent sealing membranes 2 are pressed against the corresponding surface 25 (Fig. 5).
To facilitate mechanical mechanical folding of the plates, the recesses 26, which are located asymmetrically along the periphery of the support plates, serve.
As a result of such a constructive implementation of the device, a faster return of the blood to the patient is provided.
