Description

Detailed description of the invention: Industrial application: The invention comprises a bundle of hollow fibers of approximately equal length with their ends embedded in a compound and a connection for introducing and removing at least two media. It has an approximately cylindrical casing, in which the first medium flows through the hollow fibers and the second medium is guided radially inwardly at the inlet of the casing and radially outwardly at the outlet of the casing, the casing forming an approximately tubular body and two 2. Concerning materials and/or heat exchangers consisting of two caps.

Problem to be Solved by the Invention: The object of the invention is to obtain a material and/or heat exchanger that can be produced partially or fully automatically and is structured in such a way that as many of its components as possible are reusable. be done.

Effect: Due to the arrangement of the support elements, the hollow fiber bundle can be transported or handled without damage even before it is introduced into the casing.The hollow fiber bundle with support elements corresponding to the respective requirements can also be at least The releasable connection with the casing wall allows at least the reuse of the casing wall. The casing has a connection port for introducing and discharging the medium that participates in the exchange, and since the casing requires high accuracy and sealing performance, it is possible to reuse only the casing wall instead of using the original exchanger element, that is, the hollow fiber. This becomes an important economic factor if the bundle is or has to be discarded after only one short use, as is the case for example in hemodialysis. 1. since the supporting elements do not require the same high demands as the casing; Advantageous embodiments of the exchanger according to claim 1 are described in claims 2 to 9, and can be easily manufactured with a small expenditure of energy and therefore inexpensively. A good distribution of the second medium can be achieved by forming a plurality of sheets in the range of the compound filling, such as sheets of various thicknesses wound with yarn bundles in multiple layers, a lattice-like tube, a tube with a large number of holes, or other elements as shown in the drawings, which will be described later. This is achieved if the through holes are arranged as uniformly as possible in the circumferential direction.

Furthermore, channel formations between the hollow fibers and the support element and between the support element and the casing wall must be avoided, since the medium flowing through such channels participates only insufficiently or not at all in the exchange.

For this reason, the hollow fiber bundles within the support element must be arranged with as uniform a distribution as possible, and the outer hollow fibers of the bundle must be in contact with the support element, so as to avoid the formation of free passages between the hollow fibers and the support element. The same applies to the area between the element and the casing wall. For this reason, again probably because it is desired to avoid as much as possible the formation of flow channels that would allow longitudinal flow, the support element and the casing wall are preferably arranged such that the support element is in contact with the inner surface of the casing wall in at least one length, or It is chosen such that at most only a very narrow ring passage is opened.

These last-mentioned requirements conflict with the requirement to introduce the hollow fiber bundle with supporting elements into the casing as simply and literally without friction as possible. This can be countered by forming the walls conically. One more
One solution is to use a material for the support element that swells during exchanger use, e.g. with water, so that the support element before installation can be inserted into the casing without using force and the exchanger use It has a dimension that comes into contact with the inner surface of the casing wall due to swelling.

The same is achieved by a lattice-shaped tube which is elastically deformable in the radial direction and has slightly larger dimensions than the front casing wall into which it is inserted into the exchanger casing. hollow fiber bundles consisting of hollow fibers arranged in a corrugated or other non-linear configuration;
Therefore, if a certain elongation of the hollow fiber bundle is possible, support elements are used that elongate slightly under longitudinal tension loading and can therefore be easily introduced into the casing in this state, and after cessation of tension loading. As is clear from the foregoing, the support is in particular in contact with the inner surface of the casing wall over its entire length, at least over a large part of its length, and therefore the support element is only filled between the fillings at the ends of the hollow fibers. If a porous material is used for the support, the second medium can have an outer circumference greater than the outer circumference of the area, in particular greater than the inner circumference of the casing wall of the radially (reversibly) deformable limit exchanger. The support must have a sufficient number of outwardly opening through-holes to ensure the introduction of the material during use or when using shrinking hollow fibers for the required pre-treatments, e.g. high temperature steam sterilization. In order to avoid breakage of the hollow fibers, the support element must also be deformable in the longitudinal direction by at least an amount corresponding to the contraction of the hollow fibers, which are mathematically or geometrically similar to similar cross-sections and therefore whose It represents a cross section that differs only in size, not shape.

Sealing the distribution chamber of the first medium with respect to the distribution chamber of the second medium would also facilitate the insertion of the hollow fiber bundle into the casing according to the actual convolution, in which both conno-cund fillings have similar cross-sections according to this definition. For this reason, the connection between the compound filling and the casing wall is carried out by adhesive pouring or the like, but in particular this method, which is carried out in the form of a releasable fluid-tight connection, makes it possible to use the casing wall as a reusable component. In the case of used hemodialyzers, all parts that come into contact with the patient's blood are often discarded. If the patient's blood flows through the hollow fibers, a connection cap with connections for the introduction and withdrawal of blood or dialysate is therefore also included in the drainage member.

It has become clear that it is advantageous for the connection cap to be provided with only blood inlet and outlet connections, and to connect this cap in a fluid-tight manner with the compound filling. The mouth would then be placed in the casing wall of the reusable cap and the casing wall which together form the exchanger casing would be used as a reusable member and hollow with a compound filling and supporting elements. It is advantageous to dispose of only the thread bundle, in which case the cap has a connection for the first and second medium, or, as in the proposal, only a connection for the first medium and a connection for the second medium. If the support element is of tubular design, it can be provided with a slit along at least one generatrix and therefore openable for introducing the hollow fiber bundle, which is arranged in the casing wall. It is advantageous if the hollow fiber bundle can be inserted into a fully opened support element, since it is not necessary to insert it from the end face. Since sealing of the support element is not required as is clear from the foregoing, there is no harm if the support element has a seam after the hollow fiber bundle insertion and closure.The support element with a seam is therefore part of the exchanger of the invention. or have a shape that significantly facilitates a fully automated manufacturing process.

The embodiment in which all the connections are arranged in the cap is the simplest case, having the advantage that its external dimensions can be changed without great tooling costs, since the tubular support does not have to be equipped with connections in this case. Only one through hole, which can be considered as a direct extension of the cap, is sufficient; however, a large number of through holes are generally provided.7 The through holes must be placed as close as possible to the compound.The cap is fixed to the tubular support. However, it could also be releasably arranged and reused.In this case, the second distribution chamber 11J is arranged around the outer wall of the tubular support in the form of a ring, with a number of penetrations on the periphery of the outer wall. It is particularly advantageous to provide holes. In this case, special formation of the ring-shaped cross section of the second distribution chamber, various cross sections of the through hole and/or
It is particularly advantageous that a uniform loading (introduction or removal) of the second medium onto the periphery of the hollow fiber bundle is achieved by the special distribution of the through holes on the periphery of the tubular support.

If the cross-sectional area of the through hole is different, of course 18
A large hole placed at a 0° rotation will aid in the introduction of the compound. Although the through hole will generally pass radially through the wall of the tubular support, if the ring shape of the tube wall is suitable, it will pass axially into the ring passage formed. Problems to be solved by the invention: The object of the invention is also to provide a material and/or product according to the invention which can also be incorporated into fully automatic manufacturing processes and in particular avoids sealing problems that often occur. A means for solving the problem that would be to obtain a method suitable for the manufacture of heat exchangers: The purpose was to introduce a hollow fiber bundle into the casing in the axial direction and seal both ends with a compound, in which both ends were completely sealed. Use a tubular casing, enlarged as little as possible, and install one ring body in each case at the enlarged end of the casing, the inner dimension of the free end of this ring body being the same as the outer ring of the hollow fiber bundle with the support element. Correspondingly, from this inner dimension it first passes into the inner ring of the enlarged end of the casing, and the end of the hollow fiber bundle with the introduced support element is filled with the compound in the free space of the ring body and at least partially at the enlarged end of the casing. After the compound has hardened, the ring body is removed, and then the hollow fiber bundle with supporting elements together with the cone gland is embedded tightly into the compound A/D so as to fill the free space of the compound. This is solved by cutting off the outwardly projecting ends of the casing to the extent that the outer cross-section of the compound is larger than the outer cross-section of the hollow fiber bundle.The advantages of this method are as follows: unraveling of the hollow fibers is prevented; The production of hollow fibers is automated, ensuring close contact between the compound and the casing edges when producing the module parts, and a particularly favorable sealing surface integrated with the surface of the compound is achieved in the enlarged cross-section of the compound. be done.

Another solution is to introduce the hollow fiber bundle radially into the casing and seal it at both ends with a compound.
The hollow fiber bundle with support elements is inserted into axially separated openable flexible tubes, brought into the desired closed configuration and joined at the axial separation line.

Another solution is to introduce the hollow fiber bundle axially into the casing, in which a hollow fiber bundle with support elements several times the length of the hollow fiber bundle in the finished exchanger is introduced into a multi-casing of the same length. Introducing the casing, the casing has a through hole for introducing or extracting the exchange medium in the area designated as the end,
The casing is cut into exchangers of the desired length together with the hollow fiber bundle with supporting elements located therein, and then the hollow fiber ends are sealed with a cone groove in the area between the cutting location and the through hole. Wax implementation sequence: Next, the implementation sequence of the invention will be explained with reference to the drawings. The hollow fiber bundle of the invention shown in FIG. It is deformable by a predetermined length in its length range 3 and has a seam 4 running in the length direction, the length of the element being hollow, including a compound filling 5 fixedly connected to the support element 2. Since the supporting element 2, which is the same as the thread bundle 1, consists of a grid-like tube, it is sufficient to have through holes for the supply and removal of the second medium.

FIG. 2 shows an exchange system, the two caps 6.7 and the casing wall 8 being reusable parts of the exchange system. 10, and the casing wall 8 is connected to the inlet pipe 11 and the outlet pipe 12 of the second medium.
is fixedly connected to the cap 7, but in the case of a wax system in which the cap 6 is arranged movably, the hollow fiber bundle according to the invention according to FIG.
The system can be made ready for operation by placing it over the casing tube 8. The seals required in such a device for sealing the distribution chamber of the first medium with respect to the distribution chamber of the second medium are not shown here, since their very simple form will be obvious to those skilled in the art.

Inflatable O-ring seals are particularly suitable.

In FIG. 3, an openable tubular support element 2 is shown in cross-section in the open and closed state. The use of a non-brittle material for the support element 2 in this position ensures that the reversibility of the support element 2 in the case allows bending-elastic deformation, which greatly simplifies its opening and closing. After insertion of the hollow fibers, which can be inserted by hand or by machine in the open state, the support element is closed again, the seam 4 being formed. In order to prevent the support element 2 from opening again after the hollow fiber insertion and closure, it can be provided with an elastically or form-fitting lock, for example an adhesive tape. A snap lock 14 is shown acting on the snap lock 1, the function of which is obvious and need not be explained in detail.
4 can extend over the entire length or only over a short section.When using such support elements, the ring on the inner circumference of the casing wall of the exchanger runs longitudinally between the casing wall and the support element. In order to avoid the formation of continuous channels, the casing wall is preferably provided with a longitudinally running groove on its inner surface, which corresponds to the hoop of the snap lock 14, for the purpose of accommodating the hoop of the outer circumference of the support element 2.

FIG. 5 shows one half of the support element 2, which element is releasably connected to the other body by means of a snap hinge 15, so that in the closed state this support element 2 has two seams. The through holes for introducing and removing the medium are not shown here.

A part of the hollow fiber bundle of the present invention shown in FIG. 6 includes hollow fibers 1 whose ends are embedded in a compound block 5, a support element 2 that can be deformed by a predetermined value in the longitudinal direction, and a first medium for introduction and extraction. A cap 1 having a cap 16 fixedly connected to a compound block 5 having a connection port 17-t-W.
6, a sealing surface 18 and a ring seal 19 are arranged thereon, the seal having a guaranteed deformability in the longitudinal direction by a predetermined value in order to seal the distribution chamber of the first medium to the distribution chamber of the second medium. This is achieved by uniformly distributed circumferentially deformable fins 20 that are thin compared to the remaining wall thickness of the support element 2.

The support element 2 has holes 21 between the fins 20 and the hollow fibers 1
When contracting in the longitudinal direction, the relatively thick ring-shaped portions 22 of the support element 2 deform, ie shorten, until they touch each other. The side of the hollow fiber bundle not shown in FIG. 6 is formed exactly the same as the side shown, but can also be formed without a cap.

FIG. 7 shows a part of a support element 2, which is also shown by means of this embodiment ( When changing the length of the hollow fibers (not shown), a length compensation of the support element 2 is possible as described above. The support element 2 furthermore has a ring-shaped part 23, which part of the support element 2
having a larger outer diameter than the rest of the tank and adapted to the formation and dimensions of the inner ring of the casing wall 8 of the exchanger, a seal is achieved in this position that prevents longitudinal liquid flow, and that Therefore, ring grooves may be avoided. FIG. 8 shows a lock 24 with a push-button-like cross section for the releasable support element 2. This lock is provided by the outer ring of the support element 2, for example in the case of the FIG. 4 embodiment. It has the advantage of not changing. In the case of this locking, too, a seam 4 is formed.7 Closing or retention of the releasable support element according to the invention is also carried out by gluing or welding. The individual hollow fibers 104 of the hollow fiber bundle with supporting elements are shown as straight lines.The ends of the hollow fibers 104 are shown as caps embedded in the compound 103. 101 comprises two ports 105, 106. Connection port 105 leads into a first distribution chamber 113 arranged on the end face, connection port 106 has a first distribution chamber 113 arranged on the end face, and connection port 106 has a first distribution chamber 113 formed by the wall of the substantially tubular support 102 and the connection port 106 itself. 2 into the distribution chamber 107. The noses or bulges 108 and 109 act as threaded or snap connections.From the distribution chamber 107 at least one through hole 11
0 open radially into the interior space of the tubular support, through which the second medium introduced from the connection port 106 is introduced radially inwardly between the individual hollow fibers 104 into wax distribution chambers 107
can be formed as a ring-shaped channel. The ring channels each have the same cross-section on the circumference, and the through holes 110 distributed over the ζ circumference have a diameter which increases in particular the further away from the connection opening; the through holes can also have the same diameter, with each individual The interval between the through holes becomes smaller as the distance from the connection port 106 increases.The cross-sectional area of the ring-shaped second distribution chamber 107 also becomes smaller as the distance from the connection port 106 increases. The combination of all these means acts to uniformly load the second medium onto the periphery of the hollow fiber bundle. If the other end of the mass or heat exchanger is formed in a similar manner, the first distribution chamber 106 is sealed to ensure that the radially outward conduction of the second medium also takes place uniformly over the circumference of the hollow fiber bundle. Therefore, the inner surface of the cap 101 is provided with a nose 111 that is formed at an acute angle and goes around the entire circumference.
The plunge into 03 is carried out in an area where no hollow fibers of the compound are arranged. That is, there is a small gap filled with compound between the periphery of the hollow fiber bundle and the inner wall of the tubular support 102.To seal the second distribution chamber to the outside, a screw cap, generally a nose 109, is sufficient. Fuha Seal Compound, Seal'

A particularly simple implementation is shown in FIG.
1 is inseparably connected to the tubular support 102 in this case. Since the same parts in FIG. 10 as in FIG. 9 have the same numbers, no explanation is necessary in the following FIG. 11.

In the embodiment shown in FIG. 10, the cap 101 can be connected to the tubular support 102 in the area 112 by gluing, welding or the like.

FIG. 11 shows another implementation of sealing between the individual distribution chambers 107, 113 [shown in FIJ' in this case the tubular support 10
2 is formed in the form of a (flexible) peg 0-112 which, after being fitted with a cap and snapped together at the noses 108 and 109, is pressed onto the cap, thereby achieving a particularly favorable seal.

FIG. 12 shows that the end of the tubular support can be formed by a sealing lip formed as a bellows 114.

Furthermore, FIG. 12 shows how through-holes 115 can be provided axially through the wall by forming the end region of the tubular body, and FIG. 13 shows that the material according to the invention and/or other heat exchanger formation The compound 103 exhibiting a possible ratio is here arranged in the conical part of the inner wall of the tubular support 102, and the second distribution chamber 107 is formed as a ring channel. The cross-sectional area of the through-holes has various sizes, and the through-holes 110a, 1
10b, 110c, ttoc+ and 110e become larger as the distance from the connection port 106 increases.Through holes 110e
The hollow fiber bundle 116 with supporting elements is useful when applying centrifugal pouring for introducing the substance according to the invention and the heat exchanger compound, for example polyurethane. A seal between the cap and the tubular body extending over the entire internal cross-section of the body 102 can also be achieved by an O-ring 117. The cap can also be connected with a snap connection 101a. This formation is present individually or in combination in the materials and/or heat exchangers of the invention.

FIG. 14 shows the formation of the inner wall of the tubular support 102. The inner space 118 extends approximately conically from one end region 121 to the other end region 120. Another cone 119 in the 91 end region, the conicity of which is determined by the angle α (approximately 0.5 to 1°), however, need not be provided. The cross-section side of the hollow fiber bundle with support elements (119/121
For example, a hopper can be used to cover the introduction or suction at J. The conical enlargement of the interior space facilitates the introduction of the hollow fiber bundle, and the end member 120 is slightly flared to accommodate the connectors, connectors, and connectors.

FIG. 15 shows a particularly advantageous use of the substance and/or heat exchanger according to the invention [HJ], where the wax exchanger is inserted into a dialysis machine, not shown, which is located near the separation line 128. The wax device has a blood introduction tube 122.
．． Also included are connecting tubes 122, 123, 124 and 125 for the blood outlet tube 123, the dialysate inlet tube 124 and the dialysate outlet tube 125, as well as a pneumatic cylinder 126, via the holders 127, 129 of which the cap 101, 101b is a pneumatic cylinder and 1
The cap of the exchanger according to the invention is therefore a component of the dialysis machine.
The cap 101b, of which only the tubular support 102 with support elements is a disposable member, is fixedly arranged in the holder 129, but the cap 101 is disposed axially movably via the honey-mechanical cylinder 126. When replacing the tubular support 102 with the hollow fiber bundle 116 and the support element, the cap 101 is released by means of the pneumatic cylinder, the cartridge is replaced, and the cap 101 is removed again via the pneumatic cylinder.
cover.

In order to explain the method sequence according to claim 22 with reference to FIG. 16, only one end of the casing 206, slightly enlarged at the end 207, is shown. Between the enlarged casing end 207 and the casing 206 an inlet or outlet pipe 208, for example formed as a spiral in the casing, is placed and the enlarged casing end 207 is covered or screwed with a herring body 209, which is free of its The ends are reduced to the desired cross section of the hollow fiber bundle.

In the illustrated row, the hollow fiber bundle 210 with support elements is embedded by a centrifugal flow ζ, so that the ring body 209 must be closed fluid-tight by a lid 211. The compound can be filled in an amount that fills the gap 213 up to the line 214. After solidification of the seven pounds, the ring body 209 can be removed together with the lid 211. Next, the embedded hollow fiber bundle can be used as a support element. At the same time, a cut is made, for example along line 215, in the area of the enlarged section.

In order to introduce the casing 206◇ with the IJing body 209 for the hollow fiber bundle with support elements, a vacuum is generated, whereby the hollow fiber bundle together with the support elements is sucked into the casing. If the individual hollow fibers still contain liquid during production, this liquid is likewise sucked out of the hollow fibers by means of reduced pressure.

A baffle plate 21 or a flow resistance, for example a flow resistance, can additionally be incorporated into the compound, so that during subsequent use of the module, the liquid flowing through the inlet or outlet tube is effectively guided to the compound ring (line 214). .

The method of claim 23 is clear from FIGS. 17 to 19. 216 indicates axially separated tubes along line 217. The through holes 218 serve for the inflow or outflow of the exchange medium. The illustrated hollow fiber bundle 219 with supporting elements is inserted into the open tube 216 (FIG. 18) and then the tube 216 is closed as shown in FIG. Mechanical auxiliary means 22 installed in
At each end of the closed tube connected by 0, a closing cap is installed, which closure cap contains a device for the introduction or withdrawal of two exchange media flowing through or around the hollow fiber, the tube 216 being itself hollow. FIG. 20 shows the gist of the method according to claim 24. The same with support elements is provided to a multi-casing G having several times the length of the finished exchanger. A hollow fiber bundle H of length H is introduced. Multi casing G
The multi-casing G has a through hole P for introducing or ejecting the exchange medium in the area corresponding to the casing end.The multi-casing G has a hollow fiber having a support element in the hollow which is separated in the area C together with the inner hollow fiber bundle and the support element. Seal the yarn fragments with a compound in the area between the separation position C and the through hole P.

The exchanger is then cut to the desired length by separating the disc-shaped portion of the compound with the hollow fiber sections having support elements embedded therein, exposing the unclosed hollow fiber ends. do.

The effective length as a material and/or heat exchanger is Le
It is ff. In this way, 2 to 30 or more exchangers can be produced very economically from a bundle of hollow fibers with an exchange area of, for example, 0.5 to 5 m'. The multi-casing G itself also serves as a supporting element for accommodating the hollow fiber bundle. The multi-casing G need not be formed as a substantially smooth cylinder, which facilitates the installation of a cap, for example, as shown in FIG. (Alternatively) It is also possible to produce the outer hoop with a distribution chamber with a through hole P arranged in the casing wall by blow molding. cutting the multi-casing G together with the hollow fibers (not shown) with supporting elements therein, followed by embedding the hollow fiber ends with supporting elements and exposing the unembedded hollow fiber ends; is carried out in the same manner as in FIG.
