Description

Technical Field

[0001] The utility model relates to a supporting component for an integrated blood treatment fluid module, which comprises a base body which is configured to support a blood treatment device having a cylindrical shell.

[0002] Furthermore, the invention relates to an integrated blood treatment fluid module comprising such a support member, an apparatus for extracorporeal blood treatment comprising such an integrated blood treatment fluid module, and a kit for setting up such an apparatus for extracorporeal blood treatment. Background Art

[0003] Extracorporeal blood treatment therapy generally involves drawing blood from a patient, processing the drawn blood extracorporeally by a blood processing device, and returning the processed blood to the patient.

[0004] Typically, an apparatus for extracorporeal blood treatment comprises a main frame and an integrated blood treatment fluid module removably mounted on the main frame.

[0005] For example, EP 2 263 714 A1 discloses an integrated blood treatment fluid module, which includes a blood treatment device (i.e., a hemofilter or a dialyzer) having a cylindrical housing, a fluid distribution circuit in fluid communication with the blood treatment device, and a support member for supporting the blood treatment device and the fluid distribution circuit. The support member of the prior art integrated module includes a base body with a connector, which is configured to receive and permanently engage with a corresponding mating connector of the blood treatment device.

[0006] Furthermore, EP 0 611 227 A1 discloses an integrated blood treatment fluid module comprising a support member and a blood treatment device with a cylindrical housing, which is fixedly mounted on the support member so as to be movable between a retracted packaging position and an extended operating position.

[0007] Still further, WO 01 / 08722 A2 discloses an integrated blood treatment fluid module in the form of a filter unit for a dialysis machine, comprising a blood filter having a cylindrical shell provided with several first connecting elements, a support member having several second connecting elements capable of interacting with the first connecting elements, and a locking device for releasably locking the blood filter on the support member.

[0008] As is known, such integrated blood treatment fluid modules are intended to facilitate the operation of the blood treatment apparatus, since the operator can quickly and reliably perform both the setup before the start of the treatment treatment as well as the necessary steps after the treatment is completed.

[0009] In order to install and remove from the main frame of the device, the operator must safely manipulate the integrated blood treatment fluid module. Usually, the operator uses the housing of the blood treatment device to manipulate the entire module. In order to serve as a manipulation structure, the blood treatment device must be firmly fastened to the support member and the housing must be sufficiently stable. Many times, the blood treatment device is therefore permanently fastened to the support member in a factory-finished manner. Utility Model Content

[0010] The object of the invention is to provide a supporting member of the type mentioned at the outset which allows improved handling, securely supports the blood treatment device and reduces the overall costs.

[0011] A further object of the invention is to provide a kit which enables an easy setting up of an apparatus for extracorporeal blood treatment.

[0012] Another object of the present invention is to provide an improved integrated blood treatment fluid module.

[0013] Yet another object of the present invention is to provide an improved apparatus for extracorporeal blood treatment.

[0014] These objects are achieved by a support member having the following characteristics, a kit having the following characteristics, an integrated blood treatment fluid module having the following characteristics and a device having the following characteristics:

[0015] A support member for an integrated blood treatment fluid module, comprising a base body configured to support a blood treatment device having a cylindrical housing, characterized in that a handle is permanently attached to the base body and configured to be manually grasped for manipulating the integrated blood treatment fluid module, wherein the handle comprises a concave seat surface configured to receive the cylindrical housing of the blood treatment device, the handle comprising at least one fastening portion configured to receive at least one fastening member to releasably fasten the cylindrical housing to the concave seat surface of the handle;

[0016] A kit for setting up an apparatus for extracorporeal blood treatment, characterized in that the kit comprises: a support member according to the foregoing; and a group of different blood treatment devices, the different blood treatment devices having cylindrical shells of different sizes, the cylindrical shells having different diameters; wherein the concave seat surface of the handle of the support member has a radius of curvature large enough to accommodate the largest size of the cylindrical shell of the group of different blood treatment devices, so that each of the different blood treatment devices of the group can be selectively supported on the support member;

[0017] An integrated blood treatment fluid module for an apparatus for extracorporeal blood treatment, characterized in that the integrated blood treatment fluid module comprises: a support member according to the foregoing; a blood treatment device with a cylindrical housing releasably received on the concave seat surface of the handle of the support member; and a fluid distribution circuit configured for fluid communication with the blood treatment device and supported on the support member;

[0018] An apparatus for extracorporeal blood treatment, characterized in that the apparatus comprises a main frame and an integrated blood treatment fluid module according to the above, wherein the integrated blood treatment fluid module is releasably mounted to the main frame.

[0019] According to a first aspect, there is provided a support member for an integrated blood treatment fluid module, the support member comprising a base body configured to support a blood treatment device having a cylindrical housing. The support member has a handle permanently attached to the base body and configured to be manually grasped for manipulating the integrated blood treatment fluid module, wherein the handle comprises a concave seat surface configured to receive the cylindrical housing of the blood treatment device.

[0020] The handle with its concave seat surface allows comfortable, ergonomic and safe manipulation, and at the same time allows a firm support of the blood treatment device on the base body. Therefore, the handle has two functions at the same time. On the one hand, the handle is used as a grip for the support member and therefore for the entire integrated blood treatment fluid module. On the other hand, the handle is also used as a support structure for the blood treatment device. Since the handle is permanently attached to the base body, it is not necessary to permanently attach the blood treatment device to the support member and / or its base body in order to use it as a manipulation structure. On the contrary, the blood treatment device can be provided separately from the support member. During the setup phase before starting the blood treatment treatment, the blood treatment device can be accommodated on the handle. In addition, it is possible to select a blood treatment device from different blood treatment devices with different specifications. The specifications of the blood treatment device can be selected to match the corresponding needs of the treatment or the patient. Therefore, due to the utility model, it is not necessary to provide different support members of the blood treatment device with different specifications permanently attached. This allows to simplify the production process, reduce the inventory stored at the production facilities and medical facilities, and reduce the relevant costs in general.

[0021] The support member serves as a support structure for different components of the integrated blood treatment fluid module, such as a blood treatment device, a fluid distribution circuit and / or possible other components. The support member together with the components forms the integrated blood treatment fluid module. The integrated blood treatment fluid module, in particular the support member, is configured to be mounted to a main frame of an apparatus for extracorporeal blood treatment. In one embodiment, the support member has a monolithic design, wherein the base body forms an integral part of the support member. In one embodiment, the support member has a multi-component design, wherein the base body forms one component of the multi-component support member.

[0022] For example, the blood treatment device can be a plasma filter, a hemodialysis filter, a hemofiltration filter, a hemodiafiltration filter, etc. The blood treatment device is not a component of the support member according to the utility model. The blood treatment device comprises the cylindrical (preferably circular) housing. The cylindrical housing accommodates the internal components of the blood treatment device, such as filter components, membrane components and / or possible other components. The cylindrical housing has a convex circumferential profile.

[0023] The handle is permanently attached to the base body, for example by bonding, welding or any other suitable joining technique. In one embodiment, the handle forms an integral part of the base body. The concave seat surface is configured to accommodate the cylindrical housing. The seat surface is convex relative to the transverse axis of the handle, and thereby also convex relative to the transverse axis of the blood treatment device. The concave shape of the seat surface allows stable accommodation of the cylindrical housing. In particular, the interaction between the concave seat surface and the cylindrical housing hinders relative movement along the transverse axis.

[0024] In one embodiment, the handle comprises at least one fastening portion configured to receive at least one fastening member to releasably fasten the cylindrical housing to the recessed seat surface of the handle. This hinders accidental loosening of the blood treatment device from the handle and allows for further improved safety. For example, the fastening portion may be a slot, a hook, an eyelet, etc. For example, the fastening member may be a strap, a latch, a hook and loop fastening strip, etc.

[0025] In one embodiment, the fastening portion is a slot extending continuously between lateral surfaces of the handle that are opposite to each other along the transverse axis, wherein the slot is configured to accommodate a hook-and-loop fastening strip. This embodiment allows for a simple and at the same time reliable releasable fastening of the blood treatment device. In one embodiment, the hook-and-loop fastening strip is a component of the support member and / or the integrated blood treatment fluid module. In order to fasten the blood treatment device to the handle, the hook-and-loop fastening strip is passed through the slot and surrounds the cylindrical housing by forming a closed loop. The transverse axis is perpendicular to the longitudinal axis. The handle is elongated along the longitudinal axis. With necessary fine-tuning, the same applies to the blood treatment device.

[0026] In one embodiment, the handle is elongated along the longitudinal axis between the first end and the second end, wherein the handle includes at least one end stop portion arranged at the first end or at the second end, and wherein the end stop portion is configured to limit the relative mobility of the cylindrical housing along the longitudinal axis. The end stop portion prevents the cylindrical housing from moving along the longitudinal axis. In the operating state, the longitudinal axis is preferably parallel to the vertical spatial axis, so that the end stop portion prevents the cylindrical housing from sliding downward due to gravity. The longitudinal axis is perpendicular to the transverse axis. The seat surface of the handle is concave relative to the transverse axis. Preferably, the seat surface is planar relative to the longitudinal axis. In one embodiment, the handle has a multi-part design, wherein the end stop portion forms a part of the multi-part handle. In one embodiment, the handle has an integral design, wherein the end stop portion is an integral part of the handle. In the state where the cylindrical housing is accommodated, the end stop portion contacts the end surface of the cylindrical housing. Preferably, the handle includes a single end stop portion only at one of its ends. This is conducive to accommodating blood treatment devices of different sizes on the concave seat surface.

[0027] In one embodiment, the end stop portion is a rib protruding from the concave seat surface and configured to contact the end surface of the cylindrical housing.Preferably, the rib protrudes in a normal direction of the concave seat surface.

[0028] In one embodiment, the handle includes a rear surface opposite the concave seat surface, wherein the rear surface of the handle is offset from the front surface of the base body to form a finger channel for use by the fingers of the operator's hand when grasping the handle. The finger channel allows a comfortable, ergonomic and safe grip of the handle. The finger channel extends between the rear surface of the handle and the front surface of the base body, and between lateral surfaces of the handle that are opposite to each other along the transverse axis. In order to manipulate the support member and / or the integrated blood treatment fluid module, the operator places the fingers of one hand through the finger channel while pressing the thumb onto the concave seat surface. If the blood treatment device is already mounted on the support member, the thumb can alternatively be pressed onto a cylindrical housing covering the concave seat surface.

[0029] In one embodiment, the handle comprises at least one spacer and an attachment portion protruding from the rear surface, wherein the at least one spacer and the attachment portion are permanently attached to the front surface of the base body by forming the finger channel. This is a simple and stable design. The spacer and the adjustment portion may have any suitable form and size. In one embodiment, the spacer and the attachment portion are a component of the handle, and the handle has a multi-component design. In one embodiment, the spacer and the attachment portion are an integral part of the handle, and the handle has a monolithic design. At least one spacer and the attachment portion are permanently attached to the front surface by a suitable joining technique (e.g., welding, bonding, etc.). Alternatively or additionally, permanent attachment can be achieved by means of a permanent snap fit between the spacer and the attachment portion and a complementary portion of the front surface.

[0030] In one embodiment, the handle comprises a first spacer and an attachment portion and a second spacer and an attachment portion, in particular each in the form of a cylindrical pin, arranged at longitudinally opposite ends of the handle. Both spacers and attachment portions protrude in the direction of the front surface of the base body. Providing two spacers and attachment portions at longitudinally opposite ends of the handle results in a very stable design and allows particularly safe handling of the support member and secure accommodation of the blood treatment device.

[0031] According to a second aspect, a kit for setting up an apparatus for extracorporeal blood treatment is provided, the kit comprising: a support member according to the first aspect of the utility model; and a group of different blood treatment devices, the different blood treatment devices having cylindrical shells of different sizes, the cylindrical shells having different diameters; wherein the concave seat surface of the handle of the support member has a radius of curvature large enough to accommodate the largest size of the cylindrical shells in the group of different blood treatment devices, so that each of the different blood treatment devices in the group can be selectively supported on the support member. The kit allows one of the different blood treatment devices to be selected according to the needs of a specific extracorporeal blood treatment treatment or patient, and the blood treatment device is accommodated on the concave seat surface of the handle. The radius of curvature of the concave seat surface is large enough to accommodate any one of the cylindrical shells of different sizes. The kit allows for simplified setup, simplified production processes, reduced inventory and reduced associated costs.

[0032] According to a third aspect, there is provided an integrated blood treatment fluid module for an apparatus for extracorporeal blood treatment, the integrated blood treatment fluid module comprising: a support member according to the first aspect of the utility model; a blood treatment device having a cylindrical shell releasably received on a concave seat surface of a handle of the support member; and a fluid distribution circuit configured to be in fluid communication with the blood treatment device and supported on the support member.

[0033] According to a fourth aspect, there is provided an apparatus for extracorporeal blood treatment, the apparatus having a main frame and an integrated blood treatment fluid module according to the third aspect of the invention, wherein the integrated blood treatment fluid module is releasably mounted to the main frame.

[0042] according to Figure 1 , an apparatus A for extracorporeal blood treatment is provided for therapeutic treatment, such as blood purification and water removal in case of renal failure. The apparatus A comprises an integrated blood treatment fluid module 1 and a main frame 2. The main frame 2 is depicted in a schematically simplified manner.

[0043] The integrated blood treatment fluid module 1 may be mounted on the main frame 2 in a manner that reduces pre- and post-treatment manipulation and reduces fluid interconnection requirements.

[0044] The integrated blood treatment fluid module 1 comprises a support member 10 , a blood treatment device 20 and a fluid distribution circuit 30 .

[0045] The support member 10 includes a base body 100 configured to support a blood treatment device 20. In the illustrated embodiment, the support member 10 also includes a first side body 300 and a second side body 400, both of which are optional and hingedly connected to the base body 100.

[0046] The blood treatment device 20 comprises a cylindrical housing 21 containing internal components, such as filter components, membrane components, etc. In the illustrated embodiment, the blood treatment device 20 is a dialyzer.

[0047] The fluid distribution circuit 30 is supported on the support member 10 and comprises different fluid circuits (without reference numerals), wherein at least one of the fluid circuits of the fluid distribution circuit 30 is fluidically connectable to the blood treatment device 20 .

[0048] The general function of the blood treatment device 20 and the fluid distribution circuit 30 is well known to the skilled person and is not within the focus of the present invention. Therefore, no further details on the structure and / or function of the blood treatment device 20 and the fluid distribution circuit 30 need to be given.

[0049] The support member 10 also includes a handle 200 (see also Figure 2 , Figure 3 ). The handle 200 is permanently attached to the base body 100. The handle 200 is configured to be manually grasped for manipulating the integrated blood treatment fluid module 1. In addition, the handle 200 includes a concave seat surface 201 configured to accommodate the blood treatment device 20 (see also Figure 3a ). In particular, the concave seat surface 201 is configured to accommodate the cylindrical housing 21 of the blood treatment device 20. Therefore, the handle 200 has two functions at the same time. On the one hand, the handle 200 serves as a support structure for the blood treatment device 20. On the other hand, the handle 200 serves as a grip and / or gripping structure for manipulating the support member 10 and thus the entire integrated blood treatment fluid module 1.

[0050] Since the handle 200 is permanently attached to the base body 100, it is not necessary to permanently attach the blood treatment device 20 to the support member 10 in order to use it as a gripping structure, in contrast to some prior art solutions. Therefore, the blood treatment device 20 can be provided separately from the support member 10. In the illustrated embodiment, the blood treatment device 20 is accommodated on the handle 200 just before starting the treatment, i.e. during the setup phase of the apparatus A. It is thus possible to select the blood treatment device 20 according to the needs of the respective treatment or the patient to be treated.

[0051] In the illustrated embodiment, the support member 10 further comprises a fastening member 500 configured to releasably fasten the blood treatment device 20 to the handle. In particular, the fastening member 500 is configured to releasably fasten the cylindrical housing 21 to the concave seat surface 201. The fastening member 500 interacts with the fastening portion 203 of the handle 200. The fastening portion 203 is configured to receive the fastening member 500.

[0052] In the illustrated embodiment, the fastening portion 203 is a slot 204 and the fastening member 500 is a hook and loop fastening strip 501 .

[0053] The slot 204 extends continuously between the lateral surfaces 205, 206 of the handle. The lateral surfaces 205, 206 are opposite to each other along the transverse axis T of the handle 200. The lateral surfaces 205, 206 may also be referred to as the left lateral surface 205 and the right lateral surface 206. In order to releasably fasten the blood treatment device 20 to the handle 200, the hook and loop fastening strip 501 is passed through the slot and around the cylindrical housing 21 to form a closed loop. The closed loop and / or the hook and loop fastening strip 501 can be opened and closed in a well-known manner.

[0054] The concave seating surface 201 prevents relative movement of the cylindrical housing 21 along the transverse axis T.

[0055] In the illustrated embodiment, the handle 200 includes two fastening portions 203 and has two slots 204. Figure 2 , Figure 3 , the fastening portion 203 and / or the slot 204 may be referred to as an upper fastening portion / slot and a lower fastening portion / slot. Depending on the form and size of the blood treatment device used, the upper fastening portion, the lower fastening portion or both of the fastening portions may be used to accommodate the fastening member 500. Of course, it is also possible to use two fastening members, each with one fastening portion.

[0056] In the illustrated embodiment, the handle 200 is elongated along a longitudinal axis L between a first end 207 and a second end 208. The longitudinal axis L is perpendicular to the transverse axis T.

[0057] The concave seat surface 201 is concave relative to the transverse axis T. In the illustrated embodiment, the concave seat surface 201 is planar relative to the longitudinal axis L. When received on the concave seat surface 201, the longitudinal axis L' (see Figure 5 ) is parallel to the longitudinal axis L of the handle.

[0058] The first end 207 may also be referred to as an upper end 209. The second end 208 may also be referred to as a lower end 210. When the support member 10 is mounted on the main frame 2 of the apparatus A, the longitudinal axis L is parallel to the vertical axis or height axis (no reference numeral) and / or the gravity vector (no reference numeral) of the main frame 2.

[0059] In order to prevent the blood treatment device 20 from sliding downward from the handle 200, an end stop portion 211 is provided and arranged at the second end portion 208. The end stop portion 211 is configured to limit the relative mobility of the cylindrical housing 21 in the downward direction along the longitudinal axis L. The end stop portion 211 is configured to contact the end surface 22 (see FIG. 21 ) of the cylindrical housing 21. Figure 5 The cylindrical housing 21 extends along the longitudinal axis L′ between an end surface 22 , which is a lower end surface, and an opposite end surface 23 . The opposite end surface 23 forms an upper end surface of the cylindrical housing 21 .

[0060] In the illustrated embodiment, the end stop portion 211 is a rib 212 protruding from the concave seat surface 201. The rib 212 protrudes substantially perpendicularly to the transverse axis T and substantially perpendicularly to the longitudinal axis L.
