Definitions
- This invention relates to a connector for connecting a dialysate port of a hemodialysis machine to a dialysate-carrying line according to the preamble of Claim 1 .
- hemodialysis blood is taken from a patient with the help of an extracorporeal circulation and is passed through a hemodialysis machine.
- hemodialysis machines today consist of a bundle of thousands of semipermeable hollow fiber membranes through the interior of which the blood is passed.
- a cleaning fluid the dialysis fluid or the dialysate—is circulated on the outside of the hollow fibers so that the substances to be removed from the blood enter this fluid by diffusion and/or convection.
- Such a hemodialysis machine generally has four liquid connections, which are known as ports: two for blood and two for the dialysate.
- the tubing system of the extracorporeal blood circulation and the dialysate-carrying line system in the sense of one incoming line and one-outgoing line is connected to these ports.
- standardized port forms are used for the blood ports on the one hand and for the dialysate ports on the other hand.
- the connecting system for the blood tubing system is designed to work with disposable items, the tubing used for the lines carrying the dialysate with many hemodialysis machines for treatment of chronic renal insufficiency is reusable.
- the Hansen coupling, as it is called, is used as the connecting system.
- the connection to the dialysate port is locked by a metallic ball bearing element.
- the dialysate port consists of an essentially tubular projection having a peripheral undercut upstream from the end of the port in the sense of a reduced outside diameter in which the balls of the ball bearing element engage. Between individual treatments, the dialysate-carrying lines are rinsed and cleaned together with the remaining dialysate circulation.
- disposable tube sets are also used for the dialysate-carrying lines.
- EP 0 442 310 A1 describes dialysis machine ports of a hemodialysis machine which allow connection of Hansen couplings as well as other connectors. To this end, the dialysis machine port is provided with a thread onto which a corresponding connector mating piece can be screwed.
- a screwing motion to establish the connection is a disadvantage inasmuch as it is difficult to determine the endpoint of the screwing motion. Leakage may occur if the connector is not screwed on adequately, while on the other hand, if too much force is applied to the end of the connector, it may quickly result in damage to the sealing elements, which are generally provided in these connectors.
- this connector may be used only when the ports on the dialysis machines are also designed accordingly, i.e., design measures are also required on the mating piece of the connector.
- the object of this invention is to improve upon a generic connector, so that it can be manufactured suitably as a disposable item while at the same time permitting simple and reliable connection of a dialysate-carrying line to a dialysate port of a hemodialysis machine without requiring structural measures on the dialysis machine itself.
- This invention is based on the observation that the dialysate port designed according to DIN 58352 has a peripheral undercut on the outside. This undercut can be used for a shift element that is provided on the connector designed according to this invention for locking the connector. In this case it is not necessary to redesign the port on the dialysis machine end.

Abstract
This invention relates to a connector (1) for connecting a dialysate port (31) of a hemodialysis machine with a dialysate-carrying line. The inventive connector (1) has a recess (6, 6′) with a shift element (3) on the end (4) which accommodates the dialysis machine port (31), whereby the shift element (3) is accommodated in the recess and is displaceable between a first position and a second position perpendicular to the direction of the lumen (8) on this end (4). The shift element (3) does not pass through the lumen (8) in the first position. In the first position, the lumen (8) is constricted so that the connector (1) with the shift element (3) can be placed on the dialysate port (31), and in the second position it can be locked on the dialysate port (31) by means of an undercut (30) thereon. The inventive connector is suitable for production as a disposable item in comparison with the widely used Hansen coupling. At the same time, a simple and reliable connection of a dialysate-carrying line to a dialysate port of a hemodialysis machine is possible, and does not require any structural measures on the dialysis machine itself. (FIG. 3b)
Description
- This invention relates to a connector for connecting a dialysate port of a hemodialysis machine to a dialysate-carrying line according to the preamble of
Claim 1. - During a hemodialysis treatment, blood is taken from a patient with the help of an extracorporeal circulation and is passed through a hemodialysis machine. Such dialysis machines today consist of a bundle of thousands of semipermeable hollow fiber membranes through the interior of which the blood is passed. A cleaning fluid—the dialysis fluid or the dialysate—is circulated on the outside of the hollow fibers so that the substances to be removed from the blood enter this fluid by diffusion and/or convection.
- Such a hemodialysis machine generally has four liquid connections, which are known as ports: two for blood and two for the dialysate. The tubing system of the extracorporeal blood circulation and the dialysate-carrying line system in the sense of one incoming line and one-outgoing line is connected to these ports. For the purpose of uniformity in use, standardized port forms are used for the blood ports on the one hand and for the dialysate ports on the other hand. Although the connecting system for the blood tubing system is designed to work with disposable items, the tubing used for the lines carrying the dialysate with many hemodialysis machines for treatment of chronic renal insufficiency is reusable. The Hansen coupling, as it is called, is used as the connecting system. With the Hansen coupling, the connection to the dialysate port is locked by a metallic ball bearing element. According to DIN 58352, the dialysate port consists of an essentially tubular projection having a peripheral undercut upstream from the end of the port in the sense of a reduced outside diameter in which the balls of the ball bearing element engage. Between individual treatments, the dialysate-carrying lines are rinsed and cleaned together with the remaining dialysate circulation.
- However, with other hemodialysis machines, disposable tube sets are also used for the dialysate-carrying lines. In this case it is expedient to use a design different from the Hansen coupling for the corresponding connector, in particular when the connector is also a disposable part.
- EP 0 442 310 A1 describes dialysis machine ports of a hemodialysis machine which allow connection of Hansen couplings as well as other connectors. To this end, the dialysis machine port is provided with a thread onto which a corresponding connector mating piece can be screwed.
- A screwing motion to establish the connection is a disadvantage inasmuch as it is difficult to determine the endpoint of the screwing motion. Leakage may occur if the connector is not screwed on adequately, while on the other hand, if too much force is applied to the end of the connector, it may quickly result in damage to the sealing elements, which are generally provided in these connectors. In addition, this connector may be used only when the ports on the dialysis machines are also designed accordingly, i.e., design measures are also required on the mating piece of the connector.
- The object of this invention is to improve upon a generic connector, so that it can be manufactured suitably as a disposable item while at the same time permitting simple and reliable connection of a dialysate-carrying line to a dialysate port of a hemodialysis machine without requiring structural measures on the dialysis machine itself.
- According to the teaching of this invention, this object is achieved by a connector having the features of
Claim 1. Design embodiments of this invention are the object of the subclaims. - This invention is based on the observation that the dialysate port designed according to DIN 58352 has a peripheral undercut on the outside. This undercut can be used for a shift element that is provided on the connector designed according to this invention for locking the connector. In this case it is not necessary to redesign the port on the dialysis machine end.
- Additional details and advantages of this invention are described in greater detail below on the basis of an exemplary embodiment as depicted in the drawings, which show:
-
FIG. 1 —a side view of an embodiment of the inventive connector with the shift element in the first position, -
FIG. 2 a —a view of section A-A inFIG. 1 , -
FIG. 2 b —a view corresponding to that inFIG. 2 a, showing the shift element in the second position, -
FIG. 3 a —a section through the connector fromFIG. 1 along the axis of symmetry and as seen in the direction of shifting of the shift element, whereby the shift element is in the first position, and -
FIG. 3 b —shows a view corresponding to that inFIG. 3 a, showing the shift element in the second position. -
FIG. 1 shows an embodiment of theinventive connector 1 for connecting a dialysate port of a hemodialysis machine to a dialysate-carrying line (not shown) in a side view. Theconnector 1 consists of abase body 2 and ashift element 3. Thebase body 2 is composed of a firstcylindrical sleeve 4, which is situated on the first end of theconnector 1 that is to be connected to the dialysis machine port, and a secondcylindrical sleeve 5, which is situated on the second end of theconnector 1 that is to be connected to the dialysate-carrying line. The outside diameter of the first sleeve is greater than the outside diameter of the second sleeve, which is determined by the dimensions of the lines to be connected. The two sleeves have a fluid-tight connection in a connectingarea 7, as shown inFIGS. 3 a and 3 b. A lumen (not shown inFIG. 1 ) extends through the base body of the connector, and in the case of the connection, some of the dialysate flows through this. lumen, and for the remainder, it accommodates the dialysate port of the dialysis machine. - A
recess 6 is provided on the side facing the view inFIG. 1 , and arecess 6′ is provided on the opposite side (not shown) to accommodate the shift-element 3 in thefirst end 4 of theconnector 1. Theshift element 3 is shown in the first position inFIG. 1 . It can be moved into the second position in the direction of the arrow. -
FIG. 2 a shows a sectional view A-A from the view inFIG. 1 . Theshift element 3 is in the first position accordingly. This shows thelumen 8 of the firstcylindrical sleeve 4 and therecesses shift element 3 can be moved from the first position into the second position. - The
shift element 3 also has an overall keyhole-shaped opening composed of a first round opening 9 and a secondelongated opening 10 connected to the former in the shift direction. In the first position of theshift element 3 shown inFIG. 2 a, thefirst opening 9 is arranged concentrically with thelumen 8 of thefirst end 4 of theconnector 1 so that thelumen 8 is not constricted. Thefirst opening 9 is widened slightly in anarea 11 opposite the second opening 10, so thatprojections opening 11. Recesses that are complementary to these projections are formed in therecesses projections first sleeve 4 where they are labeled as 13 and 13′. This had the advantage that thebase body 2 has mirror symmetry with respect to the plane perpendicular to the shift direction, which makes complex orientation of thebase body 2 in assembly with theshift element 3 superfluous. - Due to the engagement of the
projections connector 1 can be supplied with theshift element 3 in the first position without the user having to convince himself by actuation of theshift element 3 that thefirst opening 9 is aligned with thelumen 8 when the connector is used. Thebracket 21 on theshift element 3 then comes to a stop on thebase body 2 on the outside of the base body. - An enlarged
opening area second opening 10, running concentric with thelumen 8 when the shift element is in the second position (FIG. 2 b). In this position thesecond opening 10 constricts thelumen 8 in the direction of therecesses opening areas opening 10 directly next to the,regions shift element 3 is also held in the second position—with the dialysate port inserted (not shown inFIG. 2 b). - The spring force to be overcome can be adjusted through the desired dimensioning of a
constriction 36. Since both thebase body 2 and theshift element 3 are also preferably both made of plastic, theprojections opening areas -
Regions shift element 3 is reduced in the sense of a slope toward theopening 10 are connected to theopening areas FIG. 3 b. -
FIG. 3 a shows a section along the axis of symmetry of theconnector 1 in the direction of displacement of theshift element 3, whereby theshift element 3 is in the first position. In this view, thefirst sleeve 4 as well as the second sleeve. 5 of thebase body 2 can also be seen. Thefirst sleeve 4 has alumen 8 passing through it, and thesecond sleeve 5 has alumen 16 with a smaller diameter passing through it. There is aconstriction 17 between the two lumens. The one-piece base body is connected by a ring-like wall 7 in the connecting area between the first and second sleeves. Therecesses shift element 3 are discernible at thefirst end 4 of thebase body 2. Since theshift element 3 is in the first position, thelumen 8 is not impaired in being opened by the shift element. - The
shift element 3 is designed to be flexible enough to easily be installed in this position on thebase body 2 by spreading the leg-like borders of thefirst opening 9. This is facilitated by aperipheral slope 34, which is also shown with dotted lines inFIG. 2 a andFIG. 2 b. In assembly of theshift element 3 on thebase body 2 from the .side of thesecond sleeve 5, theshift element 3 is pressed with theround opening 9 onto thebase body 2 so that the slopingsurface 34 strikes therounded borders 35 of thebase body 2 in the connectingarea 7. This facilitates forward shifting of theshift element 3 until it engages in therecesses slope 34 may also be provided on the other side of theshift element 3 when assembly is to take place from the side of thefirst sleeve 4. - With the
shift element 3 in the first position, the inventive connector can be pushed onto to the dialysate port. Theconnector 1 is then locked by shifting theshift element 3 into the second position (FIG. 3 b). Theshift element 3 then engages behind the undercut 30, which is designed as a peripheral groove and is provided in thedialysate port 31. Thedialysate port 31 is part of adialysis machine housing 32. - The
groove 30 is provided with aslope 33 inclined toward the end of the port. Theregions slope 33. This yields an axial force input which contributes toward securing theconnector 1 on theport 31. Thedialysate port 31 is pressed against theend face 7 of thebase body 2, which at the same time serves as a stop for the port. In addition,peripheral projections element 20 which may be designed as an 0-ring, maybe be provided on the inside of thelumen 8. Thisgasket element 20 encloses the outer end of theport 31, which has a suitably reduced outside diameter at this point to achieve a reliable seal of theconnector 1 with respect to theport 31. - In the simplest case, the dialysate-carrying line—e.g., in the form of a length of tubing—may be placed on the
second sleeve 5. Depending on the requirement, fixation with a wing nut may also be provided. Other connecting methods or non-releasable connections which are preassembled, e.g., by gluing or welding, may also be used. Those skilled in the art will be familiar with a wide variety of skillful embodiments. - The inventive connector permits a connection of a dialysate-carrying line to a conventional port of a hemodialysis machine which is easy and reliable to handle. Only a few individual parts are required, and those may be manufactured inexpensively from plastics by the injection molding technique. The connector may also be used with other ports whose connections can be inserted into the first end of the connector and which have an undercut that can be gripped with the help of the shift element for the purpose of locking. This is true in particular of all ports according to DIN 58352.
