DETAILED DESCRIPTION OF AN EXAMPLE EMBODIMENT
[0070] With reference to FIG. 1, a first embodiment will be explained below. Here, FIG. 1 shows a concentrate container adapter according to a first embodiment. The concentrate container adapter has a fastening body 1. On the fastening body 1 a concentrate container, in particular a concentrate bag which is able to be filled with dry concentrate, can be mounted. The concentrate bag can be formed from a flexible material, for example PVC, PVP or polyethylene. The concentrate bag, advantageously still without dry concentrate, can be welded with the concentrate container adapter.
[0071] For the preparation of a dialysis treatment, the concentrate container adapter, with a concentrate container mounted thereon, which is now filled with dry concentrate, is fastened to a dialysis machine. In a bicarbonate dialysis, the dry concentrate is bicarbonate concentrate. The fastening body 1 has a filling opening 11. Via this filling opening 11, the dry concentrate can be filled into the concentrate container. The filling opening 11 spans a plane here. The first straight line extends perpendicularly to this plane. The filling opening 11 can be an extending tubular or ring-shaped section, as in the embodiment shown in FIG. 1.
[0072] Furthermore, the fastening body 1 has a first connection opening 12a and a second connection opening 12b. These connection openings 12a and 12b span a second straight line. A hose can be mounted respectively at the connection openings 12a and 12b, which hose projects into the concentrate bag. On at least one hose, in particular on the suction end, in addition a filter can be mounted. After filling with a dry concentrate, the filling opening 11 can preferably be closed, for example welded or glued, by a protective foil. Likewise, the first connection opening 12a and the second connection opening 12b are closed by a protective device, for example a protective foil, before a treatment. Before the start of the treatment, more precisely before pure water can be filled from the dialysis machine into the concentrate bag via the concentrate container adapter, the protective device is removed from the connection openings 12a, 12b.
[0073] During the treatment, pure water is introduced from the dialysis machine via the first connection opening 12a into the concentrate bag. In the concentrate bag, a mixing of the dry concentrate with the pure water takes place. Subsequently, the concentrate solution, now in fluid form, is directed out via the second connection opening 12b. For this, in the concentrate bag, connected with the second connection opening 12b, a hose can be arranged, which extends from the second connection opening 12b to close to end region of the concentrate bag lying opposite the second? connection opening 12b. The concentrate container adapter, on which a concentrate bag is mounted, is mounted on the dialysis machine before a treatment.
[0074] For handling, the concentrate container adapter, as illustrated in FIG. 1, can have a carrying handle, which in this embodiment is preferably formed so as to be foldable. For this, the concentrate container adapter has a housing receiving region 13 on the fastening body 1. Via this housing receiving region 13, the concentrate container adapter is mounted on the dialysis machine in such a way that the concentrate container adapter is no longer movable relative to the dialysis machine. In other words, through this housing receiving region 13 the force transmission is made possible in preferably all degrees of freedom. Via this housing receiving region 13, in particular also the weight force of the concentrate container adapter with concentrate bag is transferred to the dialysis machine, more precisely to a connector housing 10 provided for receiving the concentrate container adapter.
[0075] The housing receiving region 13 is formed here around the filling opening 11. The housing receiving region 13 can be formed in a curved shape around the filling opening 11 here, as in the embodiment shown in FIG. 1. A force absorption face 131 extends here away from the first filling opening 11. Via this first force absorption face 131 in particular the weight force of the concentrate bag can be transferred to the connector housing 10. The first force absorption face 131 forms here in the embodiment which is illustrated here an angle of substantially 90 degrees to the first straight line. To prevent the concentrate container adapter being able to shift relative to the connector housing 10, the receiving region has an edge face 132.
[0076] The edge face 132 extends from the first force absorption face 131 in a right-angled manner downwards in a direction with respect to a position arranged on the connector housing 10, i.e. contrary to the direction of gravity. As the receiving region is formed in a curved shape, it can also receive forces which act perpendicularly to the curve shape. FIG. 2 shows a further embodiment of the concentrate container adapter. In this embodiment, the housing receiving region 13 extends in a frame-like manner around the filling opening 11. Here, in particular two longitudinal struts 14a, 14b extend away on two sides of the fastening body 1. The longitudinal struts 14a, 14b extend here in particular from two opposite sides of the fastening body 1, more precisely at two sites which lie on the second straight line. The second straight line intersects a centre point of the filling opening 11 here.
[0077] Thereby it can be prevented that large tilting moments form. In particular, with a connection of the concentrate bag, i.e. a connecting of the connections on the dialysis side with the first and second connection opening 12a, 12b, a force acts on the concentrate container adapter. At an end region of the longitudinal struts 14a, 14b remote from the main body, two transverse struts 15a, 15b are situated. These transverse struts 15a, 15b are formed parallel here to the second straight line. The transverse struts 15a, 15b are formed spaced apart from one another in such a way that the concentrate container adapter, embracing the first, upper transverse strut 15a, can be easily carried, for example can be formed at a distance of 1.5 to 10 cm, preferably 2 to 8 cm. Via the lower transverse strut 15b, i.e. lying in the direction of the filling opening 11, the force transmission of the weight force onto a connector housing 10 takes place. Here, the connector housing 10, as shown in FIG. 5, has a groove-shaped mount as container receiving region 27b. The connector housing 10 can taper here conically toward the front. In other words, the circumference of the connector housing on a front face, via which the concentrate container adapter must be pushed at the start, can be smaller than at a location at which the concentrate container adapter can finally be inserted into the groove.
[0078] The lower transverse strut 15b, as illustrated in FIG. 2b, has an indent 17. Via the indent 17 the concentrate container adapter can be mounted at the correct location on the connector housing 10. In addition, the indent 17 in the lower transverse strut 15b prevents a slipping of the concentrate container adapter relative to the connector housing 10. The concentrate container adapter has furthermore a concentrate container detent element 23a. For this, an extending contour which is semi-circular in cross-section, is formed on a side face of the fastening body 1. The connector housing 10, as illustrated in FIG. 5, has a corresponding counter-contour, which can engage, more precisely latch, with the concentrate container detent element 23a. Hereby, tilting moments of the concentrate container adapter can be received.
[0079] FIG. 3 shows a further embodiment of a concentrate container adapter. Here, the housing receiving region 13 is formed on two sides of the filling opening 11. More precisely, two receiving regions, which are semi-circular in cross-section, are formed, which can shift onto a corresponding counter contour, for instance cylindrical and/or conical pins. The receiving regions therefore project laterally from the concentrate container adapter on a straight line, parallel to the second straight line. A corresponding embodiment of the connector housing 10 is illustrated in FIG. 6. In this embodiment, the pin-like extensions serve as container receiving region 27c. Here, the connector housing 10 can have on its front face an additional, third extension. The concentrate container adapter can be mounted onto this extension. For this, the concentrate container adapter can have a u-shaped recess on its carrying handle.
[0080] FIG. 4 shows perspective views of a connector housing 10 according to a first embodiment. To receive a concentrate bag, more precisely a concentrate container adapter, the connector housing 10 has a container receiving region 27a. In order to be able to feed pure water to the concentrate bag, and to be able to feed the concentrate solution out from the concentrate bag to the dialysis machine, the connector housing 10 has connection sockets, which are arranged, preferably movably, in the connector housing 10, and can thereby move from above into the mounted concentrate container adapter. Through these connection sockets, thereby a fluidic connection can be produced between concentrate bag and the dialysis machine.
[0081] In the embodiment shown in FIG. 4, the connector housing 10 has a door element 24. The door element 24 can be pivoted relative to the connector housing 10. For this, the door element 24 has a cylinder with a bore. The connector housing 10 has, for example, a second cylinder corresponding to the internal diameter of the bore. The door can be placed onto this and subsequently screwed. Alternatively, a hinge joint can connect the door element 24 with the connector housing 10. The container receiving region 27a is formed on the door element 24, wherein a concentrate container adapter of the first embodiment can be mounted via the edge face 132 of the door element 24. The container receiving region 27a, or respectively the door element, can have insertion bevels to facilitate the placing of the concentrate container adapter. Additionally or alternatively, the concentrate container adapter can have insertion bevels. For mounting the concentrate container adapter, the door element 24 is brought into an open position.
[0082] In order to be able to receive the concentrate bag, the door element 24 is formed in a curved shape. In closed position, both end regions of the door element 24 are arranged under the connector housing 10 here. In the closed position, a contact face of both end regions of the door element 24 with the connector housing 10 can exist. For this, the end region of the door element 24, which in the open position is not situated under the connector housing 10, can have a first engagement element 24a. The first engagement element 24a, as in the embodiment shown in FIG. 4, can be an indent 17 on the upper side of the door element 24. The connector housing 10 has a corresponding counter contour, for example in the form of a ball element movably mounted by a spring. When the door element 24 is situated under the connector housing 10, the ball element is pressed into the indent 17.
[0083] For detecting whether a concentrate bag, or respectively a concentrate container adapter, is situated on the connector housing 10, the connector housing 10 can have a detection unit. For this, as is illustrated in a schematic diagram in FIG. 7, a light source as transmitter, and a light receiver can be formed on the connector housing 10. The transmitter and receiver can be formed here on an underside of the connector housing 10, under which the concentrate container adapter can be received. The concentrate container adapter has on one surface a reflection geometry. When the light source transmits a light beam in a specific direction, the light impulse is received in a corresponding intensity at the light receiver only when the concentrate container adapter is arranged at a predetermined position relative to the connector housing 10.
[0084] The reflection geometry on the concentrate bag adapter can vary here, for example depending on the dry concentrate which is situated in the concentrate bag. Thereby it is not only ensured that the concentrate bag adapter is situated at the correct position, rather it is also ensured that the dry concentrate provided for a specific treatment has been prepared. When it is established that an incorrect concentrate container adapter, or this is fulfilled at an incorrect position, in other words, the reflection geometry is not detected by the receiving at the receiving unit, a start of treatment can be prevented. For example, the nursing staff can be presented with a notification, for example in the form of an alarm.
[0085] In a further embodiment, the connector housing 10 can have as detection unit a colour sensor as receiver and a light source as transmitter unit. Accordingly, as in the schematic diagram shown in FIG. 8, the concentrate bag or the concentrate container adapter can have a colour marking. Here, according to the colour coding, it can be detected which type of dry concentrate, which concentrate bag type, for example differentiated according to the filling quantity, and a correct positioning can be detected. Also in this embodiment, light source and colour sensor can be formed on an underside of the connector housing 10. As a further embodiment, a radar sensor can be arranged on the connector housing 10, and can detect the position and the presence of the concentrate bag adapter, or respectively concentrate bag.
[0086] FIG. 9 shows a schematic diagram of a further embodiment of the detection unit. Also in this embodiment the connector housing 10 has a transmitter unit and receiver unit. The transmitter unit here is a light source. The receiver unit is arranged on the connector housing 10 in such a way that it receives a light impulse only when the correct concentrate bag or respectively concentrate container adapter is situated at the correct position. This is ensured on the basis of the characteristic refractive index of the material which is used. Here, the refractive index of the concentrate bag or concentrate container adapter is taken as the basis for the expected reflection angle. When at a correspondingly positioned receiver unit no previously defined light impulse is received, the previously mentioned conditions of the correct concentrate bag and/or position thereof are not fulfilled. Here, as illustrated in FIG. 9, the receiver unit can be formed on a side of the connector housing 10 lying opposite the underside of the connector housing 10 at an angle.
[0087] FIG. 10 shows a further embodiment of the detection unit. Here, the connector housing 10, at a position at which the concentrate bag, or respectively the concentrate container adapter is situated in a correct position, has at least one, but preferably several microswitches. As shown in FIG. 10, the concentrate container adapter can have two projections arranged on the inner sides of the longitudinal struts 14a, 14b. The microswitch on the side faces of the connector housing 10 can be arranged directly behind an elastomer layer, so that with a pressing-in, it is triggered by the projections of the microswitches. The coding of different concentrate bags can take place here via the position of the microswitches on the housing.
[0088] FIG. 11 shows a schematic diagram of a receiving device 3 according to a first embodiment. In the receiving device 3 a concentrate container adapter can be received here, and the receiving device itself can be mounted on the connector housing 10 via a mounting region. In addition, the receiving device 3 has a sliding region 32 and a receiving region 31. Thereby, the receiving region 31, in which a concentrate container adapter is received, can be fed to the connector housing 10 via the sliding region 32. The nursing staff can therefore insert the concentrate container adapter with concentrate bag into a region which is easy to reach. The feeding of the concentrate container adapter itself than takes place via the sliding region 32.
[0089] As is illustrated in FIG. 11, the sliding region 32 is formed here as a bar slide, for example as a rigid element. The sliding region 32 can be formed from two track elements running in a parallel manner, and the receiving region 31 can be formed in a curve-shaped manner between end sections of the track elements. Via the rigid element, the concentrate container adapter can be moved or respectively can slip under the connection sockets of the dialysis machine. The receiving region 31 is aligned horizontally as a rotationally movable element at the start, so that the concentrate container adapter remains therein. After completion of the cleaning of the dialysate circuit, the rotationally movable element, the receiving region 31, can tilt and thereby move the concentrate container adapter via the rigid element, the sliding region 32, under the connector housing 10. Thereby, the concentrate bag can be inserted by the nursing staff into the receiving device 3 at any desired time, independently of the progress of cleaning.
[0090] FIG. 12 shows a schematic diagram of a receiving device 3a according to a second embodiment. The receiving device 3a has a receiving region 31a with fastening element. In this receiving region 31a the concentrate container adapter can be fastened. Furthermore, the receiving device has a moving region 32a. Via this moving region 32a, the distance between the receiving region 31a and the mounting region can be changed so that the receiving region 31a with the received concentrate container adapter can be fed to the connector housing 10 for connection. At the start, the nursing staff inserts the concentrate container adapter into the receiving region 31a. This can take place independently of the progress of the cleaning. After completion of the cleaning, the moving region 32a moves the concentrate container adapter to the connector housing 10, for connection under the connection sockets. The moving region 32a can be formed as a telescope mechanism or as a folding mechanism.
