technical field

The utility model relates to an adapter for fixing a fixing belt on a patient table and a patient table, and the adapter is fixed on the patient table at least when needed. the

Background technique

If a patient is to be examined by means of an imaging medical device, such as a computed tomography machine, the patient being examined is often placed on a patient table. Furthermore, in order to avoid sports injuries and/or to prevent injuries, the patient is sometimes fixed on the patient table, for example by means of straps. For this reason, such a patient table is usually provided with a fastening or safety belt system. the

Contents of the invention

Therefore, the technical problem to be solved by the present invention is to provide an improved solution for securing a patient on a patient table. the

The above-mentioned technical problem is solved by an adapter according to the utility model. Likewise, the above-mentioned technical problem is also solved by a patient table according to the present invention. the

Within the framework of the identification of potential weaknesses of existing solutions for immobilizing the patient, in particular of existing safety belt systems, it can be found that a series of different safety belt systems are currently used, which are considered disadvantageous especially by the operators of the respective medical devices of. the

The adapter described below is used for fastening at least one fixing strap or safety belt on the patient table, wherein the adapter has a first fastening element for detachably fastening the adapter on the patient table and is used for fastening, preferably with Second fixing for detachably fixing the strap or harness to the adapter. This achieves the effect that different fastening straps or harness systems can be used on patient tables of different designs, even if these are not compatible with each other with regard to their respective fastening concept. However, it is preferably provided that a uniform fastening strap system is used for different medical devices, such as computed tomography scanners and magnetic resonance imaging machines, and that this fastening strap system is fastened by means of adapters to patient tables of different designs. In addition, the strap systems typically include more straps and/or mesh straps that differ in design, and the strap systems also include some of the same straps as a set of straps use together. the

This is precisely an advantage for medical facilities, where, when using different medical instruments with differently designed patient tables, by defining a single fastening strap system for all medical facilities, on the one hand cost savings can be achieved, on the other hand, The operator in charge of (handling) the device does not have to worry about the different operating protocols of the different strap systems. Furthermore, due to the fastening of the adapters on the respective patient table and preferably also the fastening of the fastening strap system, i.e. the fastening of the fastening straps to the adapters is reversibly detachable to a certain extent, the fastening system for fastening the patient suffers the least wear and tear. A strong component (usually a fixing strap), which is particularly easy to replace when required. the

Furthermore, an advantageous embodiment of the adapter consists in that the adapter is designed in the form of a decking for the patient table. Thus, the adapter is placed on the top of the respective patient table and is secured against horizontal movements, ie perpendicular to the surface normal of the top, by means of the first fixing. Furthermore, relatively low forces can be expected, so that fastening devices can also be used that can be removed particularly easily. the

Furthermore, the adapter advantageously comprises two rails, which are preferably interconnected by at least one transverse connecting means. In particular, the transverse connection is designed in the form of a strip, wherein the strip-shaped transverse connection is produced from a rigid or flexible material, depending on the intended use. When using flexible materials, the distance between the rails can be varied to suit the individual patient table, and only a maximum value for this distance can be specified constructively. In contrast, when using a rigid material, fixed distances are prescribed, whereby a very stable basic structure for the adapter, consisting of rails and transverse connections, can be achieved. Those basic structures consisting of rails and transverse connections are placed on the respective patient table and fastened thereto by means of first fastening elements, wherein the rails are positioned on the patient table at the edge. After the patient is positioned on the patient table, his body lies flat on the transverse connecting device, wherein the patient does not feel any discomfort due to the strip-shaped design of the transverse connecting device. the

If flexible transverse connections are provided, they are preferably made of polyurethane-coated leather, and if rigid transverse connections are provided, they are preferably made of polyethylene. Said transverse connection means and/or said track are optionally made of polyether ether ketone. In any case the material selection was based on different ideas. For example, it is advantageous for the overall weight of the adapter to be as light as possible, so that the operator can easily keep it in operation. Another important criterion for material selection is the life expectancy of the adapter, taking into account the accelerated aging process of various materials exposed to intense X-ray radiation. The most important criterion when selecting suitable materials is their interaction with electromagnetic fields, since negative influences during imaging must be prevented by the adapter. Therefore, when using computed tomography, the material should be almost transparent to x-rays, and when using magnetic resonance tomography, the material should not have relevant magnetic properties. the

Furthermore, the first fastening part preferably includes a Velcro strap (Klettband) for forming a Velcro connection to the patient table. In this case, the corresponding fitting is fastened on each patient table on which the adapter is to be used, wherein the fastening of the fitting takes place once and is preferably designed as a non-detachable fastening, so that between the adapter and the individual patient table The detachable fastening between them is carried out by Velcro connection. The corresponding Velcro connection is particularly easy to use, sufficiently strong, durable and inexpensive to produce. the

Furthermore, the adapter is expediently designed in that each rail has a tongue, on which the Velcro is fastened. This advantageously defines the surface for the Velcro connection. Furthermore, it is provided in a further advantageous refinement of the invention that when the adapter is used, the tongues of the rail rest on the respective patient table on the edge side when the other rail body protrudes beyond the lying surface of the respective patient table. The rail has a high space requirement even without taking into account the tongue, and in this way the lying surface available for the patient is not restricted. the

Preferably, each track has, as a second fixing, a mounting seat designed to receive an insert fixed to a fixing strap. The mount and the insert serve as a universal interface for forming a detachable connection between the adapter and the strap, so that ultimately all straps and different straps of the strap system can be used with the aid of an adapter on each patient table equipped with an adapter. Type-designed fastening straps, each with a corresponding insert. Thus, with the aid of an adapter, the fastening solution is advantageously also suitable for special safety belts that are not commonly used, in which case it is generally sufficient, for example, to only have one corresponding special safety belt in stock, which can be used for all patient table. the

Furthermore, the mount is preferably designed as a linear guide for the insert in the longitudinal direction of the rail, wherein, for fastening, the mount encloses the insert transversely to the longitudinal direction of the rail in such a way that an opening remains transverse to the longitudinal direction of the rail gap. Such a design of the mount is particularly advantageous when the fixing strap is wound on a reel and when the reel itself is used as an insert and thus inserted into the mount if necessary. The drum can be moved longitudinally along rails within the mount and can be conveniently orientated relative to the patient in a simple manner. To immobilize the patient, the strap is unrolled from the roll and led out of the mount through the open gap. the

In an advantageous development, the mount and the insert cooperate in the manner of a sliding joint or a rotary sliding joint, so that the insert can thus be positioned relative to the patient easily and flexibly. the
