Reporters obtained the following quote from the background information supplied by the inventors: "In medical devices with extracorporeal blood circulation, i.e. especially in medical devices for blood purification, filters permitting the substance exchange are used. Said filters can be fastened or held at the medico-technical device. For reasons of handling said holders are conventionally arranged at exposed positions and are configured to be movable.
"Frequently, said holders are in the form of a removable accessory and have to be mounted at an appropriate position by the operator of the device. However, this entails the risk of the holder being arranged at an inappropriate position or being used in a not intended manner. Furthermore it is possible that the holder is removed from the device and then the device cannot be operated.
"If the holder is rigidly connected to the housing of the device, however, there is a risk that the holder is dismounted when bottlenecks such as door frames are passed and that in this way damage of the medico-technical device occurs."
In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "Therefore it is the object of the invention to provide a robust support for a medical functional member which prevents faulty operations.
"It is a further object of the invention to provide a medical device for extracorporeal blood treatment including such support.
"The holding device for a medical device according to aspects of the invention includes a holder and a second component part on which the holder is mounted or to which the holder can be coupled, respectively, wherein the holder includes a receiving portion to which a functional member can be detachably introduced or connected. The second component part has a recess inside of which a support movable vis-a-vis the second component part in a spring-loaded manner is arranged. The holder in turn is pivoted about an axis of rotation to the support, wherein a tensile force can be applied to the holder by the spring-loaded support. Furthermore the holder or the recess is configured such that upon pivoting the holder about the axis of rotation a pivoting portion of the holder moves within the recess while the receiving portion protrudes from the recess.
"This design of a holding device can increase the ruggedness of the same, for the resilient connection of the holder to the second component part protects both component parts from damage. In addition, the holder can be pivoted about an axis of rotation which can be brought about with intent but also unintentionally. Intended pivoting motions permit the well-directed positioning of the holder at a particular position and in the case of unintended impacts the holder deviates without any fractures or breaks occurring in component parts.
"When the second component part is a medical device for extracorporeal blood treatment or the housing of such medical device, for example, a dialyser or a holder for receiving a dialyser can be mounted on the holding device. When bottlenecks are passed, the holder cannot be pulled off and the medico-technical device is not damaged. Only the receiving portion protrudes from the housing, while the pivoting portion is largely provided inside the recess in the housing and thus can close off the housing to the outside. The area between the pivoting portion of the holder and the recess imay be bridged by a cover or is even sealed by a sealing.
"By the holding device according to aspects of the invention a holder for accommodating a functional member can be integrated in the field of handling of an operator at a suited position, whereby faulty operations are prevented. The holder is moreover integrated in the second component part in such manner that it cannot be removed. The operation of a medical device thus cannot be impaired by a missing holder. Furthermore, it is also possible to integrate further elements such as tube holders into the holder so as to be able to accommodate e.g. drip chambers and/or tubes.
"In an embodiment of the invention the second component part includes means for delimiting pivoting of the holder between two defined end positions. For this, at the second component part for example two stops can be formed each of which contacts a stop face at the pivoting portion of the holder at the two defined end positions. Thus the holder cannot be pivoted beyond the end positions. The stops may be designed, however, so that they stop the pivoting motion of the holder before the latter contacts housing parts which otherwise might be damaged. This is especially the outer rim of the recess in the housing inside which the holding device is arranged. For, if the holder abuts against the rim during pivoting, breaking might be entailed.
"The holder can be movably mounted on the second component part via a connecting bolt or pivot bolt, for instance, which is guided through an eye of the support, each of the two end portions of the connecting bolt being introduced in a receiving portion at the second component part. In this way an axis of rotation can be formed about which the holder is pivotable. In an embodiment of the invention, the receiving portions are provided at a bolting plate that is detachably mounted on the second component part. Such bolting plate especially has the advantage that the required geometry of the holding device need not be formed in the housing, which facilitates the manufacture of the housing. Rather, the bolting plate can be appropriately shaped and bolted to the housing. The bolting plate can also be made of a material different from that of the second component part and/or the holder.
"In another embodiment of the invention, a friction brake by which the pivoting motion of the holder about the axis of rotation can be decelerated is provided at the holding device. This has the advantage that both intended and unintended pivoting motions are decelerated, which further reduces the risk of damage of a component. In order to realize a friction brake at least two plate- or disk-shaped braking elements can be formed at the pivot portion so that they are in permanent contact with the support upon pivoting the holder, wherein the braking elements contact the support on two opposed sides and extend transversely to the axis of rotation.
"Furthermore, aspects of the invention include a medical device for extracorporeal blood treatment including a housing and a holding device including a holder for accommodating a functional part of the medical device, the holding device being configured according to the invention. The functional part to be accommodated then can be a dialyser, for example, or a further holder for accommodating the dialyser. Such medical device can make use of the advantages of the holding device according to the invention and is especially protected against damage. However, the holding device can also be provided at other medical devices in which a robust support for a functional member is to be provided.
