The invention is based on a magnetic resonance system comprising a scanning unit, a patient receiving region at least partially enclosed by the scanning unit, and a housing unit enclosing the scanning unit, wherein the housing unit has a housing enclosing the patient receiving region and a housing element adjoining the housing. According to the invention, the housing unit has at least one sealing element which is arranged between the housing and the housing element adjoining the housing.
The magnetic resonance system preferably comprises a medical magnetic resonance system and/or a diagnostic magnetic resonance system which are designed and/or designed for the examination of medical image data and/or diagnostic image data, in particular medical magnetic resonance image data and/or diagnostic magnetic resonance image data, of a patient. For this purpose, the magnetic resonance apparatus comprises a scanning unit. The scanning unit of the magnetic resonance apparatus preferably comprises a detector unit, in particular a magnet unit, for detecting medical image data and/or diagnostic image data. The scanning unit, in particular the magnet unit, advantageously comprises a basic magnet, a gradient coil unit and a radio-frequency antenna unit. The radio-frequency antenna unit is fixedly arranged in the scanning unit and is designed and/or designed to emit excitation pulses. For the detection of magnetic resonance signals, the magnetic resonance apparatus has a local radio-frequency antenna unit which is arranged around a region of a patient to be examined.
The basic magnet of the scanning unit is designed to generate a homogeneous basic magnetic field having a defined and/or specific magnetic field strength, for example a defined and/or specific magnetic field strength of 3T or 1.5T or the like. The basic magnet is designed in particular to generate a strong, constant and homogeneous basic magnetic field. The homogeneous basic magnetic field is preferably arranged and/or located in a patient receiving region of the magnetic resonance system. The gradient coil units are designed to generate magnetic field gradients which are used for spatial encoding during imaging.
The patient receiving region is designed and/or designed to receive a patient, in particular a region of the patient to be examined, for performing a medical magnetic resonance examination. For this purpose, the patient receiving region is formed, for example, cylindrically and/or is surrounded cylindrically by the scanning unit. For this purpose, the scanning unit has a housing of the housing unit which at least partially encloses the patient receiving region. The housing of the scanning unit preferably cylindrically encloses the patient receiving region.
A Field of View (FOV) and/or an isocenter of the magnetic resonance system is preferably arranged in the patient accommodation region. Preferably, the FOV comprises an examination region of the magnetic resonance apparatus, in which examination region conditions, for example a homogeneous basic magnetic field, exist for examination of medical image data, in particular magnetic resonance image data, in the patient accommodation region. The isocenter of the magnetic resonance apparatus preferably comprises a region and/or point within the magnetic resonance apparatus having optimal and/or ideal conditions for detecting medical image data, in particular magnetic resonance image data. The isocenter includes, among other things, the most homogeneous magnetic field region within the magnetic resonance apparatus.
The housing unit typically has a plurality of housing elements and/or housing shells which together enclose the scanning unit. The first housing element here comprises a casing which surrounds the patient accommodation region. The housing surrounding the patient receiving area can also comprise the side of the radio-frequency antenna unit of the scanning unit facing the patient receiving area and/or be formed integrally with the side of the radio-frequency antenna unit facing the patient receiving area. The housing element of the housing unit adjoining the patient receiving area preferably comprises a housing element which surrounds the insertion opening of the patient receiving area. The housing element surrounding the introduction opening preferably comprises a funnel element of the housing unit. The housing surrounding the patient receiving area and the housing element adjoining the housing are preferably housing elements directly adjoining one another, so that no further housing elements are provided between the housing and the housing element adjoining the housing.
The transition between the housing surrounding the patient receiving area and the housing element adjoining the housing should be sealed as well as possible. On the one hand, in order to prevent contaminants, such as body fluids, from entering the scanning unit. On the other hand, the sealing of the transition also has a sound-damping function, so that noise disturbances in the patient accommodation region can be kept as low as possible. The transition between the housing and the housing element, in particular the funnel element, adjoining the housing has an intermediate space and/or gap, which is sealed by at least one sealing element of the housing unit. For this purpose, at least one sealing element is arranged between a housing surrounding the patient receiving area and a housing element adjoining the housing. The intermediate space and/or the gap between the housing surrounding the patient receiving area and the housing element adjoining the housing is typically formed so as to surround in the circumferential direction of the patient receiving area. For sealing, the housing unit may have a single sealing element which is formed in a circumferential manner, in particular in an annular manner, and which is arranged in a gap and/or transition between the housing surrounding the patient receiving region and a housing element, in particular a funnel element, adjoining the housing. Alternatively, the housing unit can also have a plurality of sealing elements which are arranged in succession in the circumferential direction between the housing surrounding the patient accommodation region and the housing element adjoining the housing.
The invention makes it possible to achieve a simple and cost-effective seal between the housing and the housing element adjoining the housing. In particular, during a magnetic resonance examination, the scanning unit can be protected from undesired ingress of contaminants, for example of bodily fluids. Furthermore, the emission of noise through the gap and/or the intermediate space can also be advantageously prevented by the at least one sealing element, so that noise disturbances on the patient during the magnetic resonance examination are minimized and/or significantly reduced.
In a further embodiment of the magnetic resonance apparatus according to the invention, it can be provided that the at least one sealing element is arranged adjacent to the housing element of the housing in a form-fitting and/or force-fitting and/or material-fitting manner. In this case, the at least one sealing element can be bonded, for example, to a housing element, in particular a funnel element, which adjoins the housing. In addition, the housing element adjoining the housing and/or the at least one sealing element may have a recess and/or a web which corresponds to the recess and/or the web of the housing element adjoining the housing, so that the at least one sealing element is positively connected, for example by a locking connection, and/or is connected in a force-fitting manner, for example due to stiction and/or adhesion, with the housing element adjoining the housing, in particular the funnel element. This makes it possible to provide a simple arrangement and/or fastening of the at least one sealing element on the housing element adjoining the housing. In particular, when removing and/or disassembling the housing element, in particular the funnel element, which adjoins the housing, as may be necessary, for example, in maintenance work, the at least one sealing element can be removed together with the housing element adjoining the housing in a particularly simple and time-saving manner. The at least one sealing element preferably rests against the housing, so that a simple removal or a simple removal of the at least one sealing element from the housing can be achieved.
In an alternative embodiment, the at least one sealing element can also be arranged in a force-fitting and/or form-fitting and/or material-fitting manner on the housing surrounding the patient receiving region and only in contact with the housing element adjoining the housing.
In a further embodiment of the magnetic resonance apparatus according to the invention, it can be provided that the at least one sealing element has a recess and the housing element adjoining the housing has a projection, wherein the recess and the projection are formed in correspondence with one another. When the at least one sealing element is arranged on the housing element adjacent to the housing, the projection of the housing element adjacent to the housing preferably forms an annular projection in the circumferential direction of the patient accommodation region. Furthermore, the recess of the at least one sealing element forms an annular recess in the circumferential direction of the patient receiving region. In this case, the only annular sealing element can have an annular recess. Furthermore, it is also conceivable for two or more sealing elements arranged one behind the other in the circumferential direction of the patient receiving area to together form an annular recess. The width and/or cross section of the recess of the sealing element preferably at most corresponds to the width and/or cross section of the projection of the housing element adjoining the housing. It is furthermore advantageous if the depth of the recess of the sealing element corresponds to the depth of the projection of the housing element adjoining the housing.
The utility model discloses a design has following advantage: it is possible to provide the at least one sealing element simply and time-effectively on the housing element adjoining the housing for mounting the at least one sealing element. In particular, the at least one sealing element can be mounted by simply inserting it onto a projection of the housing element adjoining the housing. Furthermore, if the projection and the recess are formed in a precisely fitting manner with respect to one another, a non-positive fastening between the at least one sealing element and the housing element adjoining the housing can be achieved without additional fastening elements being required.
In a further embodiment of the magnetic resonance apparatus according to the invention, it can be provided that the at least one sealing element has a web-shaped element of zigzag design, and the housing element adjoining the housing has a recess corresponding thereto. The width and/or cross section of the recess of the housing element adjoining the housing preferably corresponds at most to the width and/or cross section of the web-shaped element of the sealing element. When the at least one sealing element is arranged on the housing element adjacent to the housing, the recess of the housing element adjacent to the housing preferably forms an annular recess in the circumferential direction of the patient accommodation region. Furthermore, the web-shaped element of the at least one sealing element forms an annular web-shaped element in the circumferential direction of the patient receiving area. The only annular sealing element can have an annular web-shaped element. Furthermore, it is also conceivable for two or more sealing elements arranged one behind the other in the circumferential direction of the patient receiving region to together form an annular web-shaped element.
The utility model discloses a design has following advantage: it is possible to provide the at least one sealing element simply at a housing element adjoining the housing for mounting the at least one sealing element. In particular, the at least one sealing element can be mounted by simple insertion into a recess of the housing element adjoining the housing. Furthermore, if the web-shaped element and the recess are formed in a precisely fitting manner with respect to one another, a non-positive fastening between the at least one sealing element and the housing element adjoining the housing can be achieved without additional fastening elements being required.
In a further embodiment of the magnetic resonance apparatus according to the invention, it can be provided that the at least one sealing element is formed in one piece and/or in one piece with a housing element adjoining the housing. The housing unit preferably comprises a single sealing element which is formed in one piece and/or integral with the housing element adjoining the housing. In this context, one-piece and/or one-piece is to be understood in particular to mean that the sealing element and the housing element adjoining the housing form a single component which can always be mounted and/or dismounted together. In particular, disassembling and/or disassembling the component by removing the sealing element may cause a destruction of the sealing element and thus a loss of functionality of the sealing element. For example, the sealing element can be injected and/or applied to the housing element adjoining the housing by an injection molding method, for example an injection molding method. In this case, the housing element, in particular the funnel element, adjacent to the housing is preferably introduced into an injection mold and the sealing element is subsequently injected. In this way, a particularly compact arrangement of the sealing element in the housing unit can be achieved. In addition, this also allows for a simple installation of the sealing element, since the sealing element is already mounted on the housing of the patient accommodation area together with the installation of the housing element, in particular the funnel element, adjacent to the housing.
In a further embodiment of the magnetic resonance apparatus according to the invention, it can be provided that the at least one sealing element comprises a sealing ring, wherein the sealing ring has a diameter corresponding to a diameter of a housing surrounding the patient accommodation region. The housing unit preferably comprises a single sealing element, which is designed as a sealing ring. The diameter of the sealing ring gives the inner diameter of the sealing ring. Furthermore, the diameter of the housing surrounding the patient receiving area also includes the inner diameter of the housing surrounding the patient receiving area. Such a sealing ring can be produced, for example, by means of an injection molding method, so that a single large 3D seal can be used for mounting the sealing element. This advantageously makes it possible to achieve a gap-free sealing of the intermediate space and/or gap between the housing surrounding the patient accommodation region and the housing element adjoining the housing. In particular, a boundary seam between two sealing elements abutting against one another can thereby be advantageously prevented.
In a further embodiment of the magnetic resonance apparatus according to the invention, it can be provided that the at least one sealing element comprises an overlap region which covers an edge region of the housing which surrounds the patient accommodation region. The edge region of the housing surrounding the patient receiving region is preferably arranged at the edge region facing the housing element adjoining the housing, in particular the funnel element. In the position of mounting on the housing element adjacent to the housing, the overlapping region of the at least one sealing element preferably faces the housing surrounding the patient receiving region. The overlap region of the at least one sealing element can here bear against the housing on the side of the housing facing the patient receiving area or on the side of the housing facing away from the patient receiving area.
Through the design of the utility model, can realize favorable acoustics between the gradient coil unit of scanning unit, especially scanning unit and patient hold the region. As a result, undesired noise disturbances of the patient during the magnetic resonance examination can be minimized, so that a dwell of the patient in the patient accommodation region can be arranged more comfortably during the magnetic resonance examination.
In a further embodiment of the magnetic resonance apparatus according to the invention, it can be provided that after the at least one sealing element has been installed between the housing surrounding the patient receiving region and the housing element adjoining the housing, the overlapping region of the at least one sealing element rests under pretension against an edge region of the housing surrounding the patient receiving region. In this way, an advantageous sealing of the intermediate space and/or the gap between the housing surrounding the patient accommodation region and the housing element adjoining the housing can be achieved in a structurally simple manner. In addition, this also makes it possible to provide a simple removal of the at least one sealing element from the housing surrounding the patient receiving area, as is expedient for example for maintenance work.
In a further embodiment of the magnetic resonance apparatus according to the invention, it can be provided that the housing surrounding the patient receiving region has an edge region with a recess at a side facing the patient receiving region, wherein the recess has a height corresponding to the thickness of the overlapping region of the at least one sealing element. The edge region with the recess preferably faces the housing element adjoining the housing. The recess of the edge region of the housing advantageously forms an overlap region for the arrangement of at least one sealing element, in particular of at least one sealing element. It is thereby advantageously possible to achieve that the at least one sealing element is flush with the patient receiving area, so that a planar and/or flat surface is formed with the housing surrounding the patient receiving area. Furthermore, it is advantageously also possible in this way to prevent at least one sealing element, in particular the overlapping region of at least one sealing element, from undesirably protruding into the patient receiving region. This also allows for a simple cleaning of the patient receiving area without undesired damage of the at least one sealing element occurring in the process.
In a further embodiment of the magnetic resonance apparatus according to the invention, it can be provided that the at least one sealing element comprises a light-resistant and/or wear-resistant material. For example, the material of the at least one sealing element may comprise silicone and/or silicone rubber and/or EPDM (ethylene propylene diene monomer) and/or TPE (thermoplastic elastomer) and/or other materials that appear to be of interest to the person skilled in the art. The utility model discloses a design has following advantage: it is possible to provide a sealing element with less wear, so that a durable sealing element can also be provided.
In a further embodiment of the magnetic resonance apparatus according to the invention, it can be provided that the housing element adjoining the housing has a housing element which surrounds the insertion opening of the patient receiving region. The housing element surrounding the introduction opening of the patient receiving region preferably comprises a funnel element of the housing unit. The design of the invention makes it possible to achieve an advantageous sealing in the critical region of the housing unit. In this critical region, on the one hand, as little noise as possible should pass from the scanning unit, in particular the gradient coil unit of the scanning unit, into the patient accommodation region, and, on the other hand, the housing unit should protect the scanning unit in this region from the ingress of liquids and/or other contaminants.

Detailed Description
A magnetic resonance apparatus 10 is schematically shown in fig. 1. The magnetic resonance apparatus 10 comprises a scanning unit 11 formed by a magnet unit. Furthermore, the magnetic resonance apparatus 10 has a patient receiving region 12 for receiving a patient 13. The patient receiving region 12 in the present exemplary embodiment is cylindrical and is surrounded in the circumferential direction by the scanning unit 11, in particular a magnet unit, in a cylindrical manner. In principle, however, a different design of the patient receiving region 12 is conceivable anyway. The patient 13 can be pushed and/or moved into the patient receiving region 12 by means of the patient support 14 of the magnetic resonance apparatus 10. For this purpose, the patient support device 14 has a table 15 which is designed so as to be movable within the patient receiving region 12. In particular, the table 15 is mounted so as to be movable in the direction of the longitudinal extent of the patient receiving region 12 and/or in the z direction.
The scanning unit 11, in particular the magnet unit, comprises a superconducting basic magnet 16 for generating a strong and in particular constant basic magnetic field 17. Furthermore, the scanning unit 11, in particular the magnet unit, has a gradient coil unit 18 for generating magnetic field gradients for spatial encoding during imaging. The gradient coil unit 18 is controlled by means of a gradient control unit 19 of the magnetic resonance apparatus 10. The scanning unit 11, in particular the magnet unit, further comprises a radio frequency antenna unit 20 for exciting a polarization which occurs in the basic magnetic field 17 generated by the basic magnet 16. The radio-frequency antenna unit 20 is controlled by a radio-frequency antenna control unit 21 of the magnetic resonance apparatus 10 and injects radio-frequency magnetic resonance sequences into the patient accommodation region 12 of the magnetic resonance apparatus 10.
For controlling the basic magnet 16, the gradient control unit 19 and for controlling the radio-frequency antenna control unit 21, the magnetic resonance apparatus 10 has a system control unit 22. The system control unit 22 centrally controls the magnetic resonance apparatus, for example, to execute a predetermined imaging gradient echo sequence. Furthermore, the system control unit 22 comprises an evaluation unit, not shown in detail, for evaluating medical image data detected during the magnetic resonance examination.
Furthermore, the magnetic resonance apparatus 10 comprises a user interface 23 connected to the system control unit 22. The control information, e.g. the imaging parameters, and the reconstructed magnetic resonance image may be displayed for the medical operator on a display unit 24 of the user interface 23, e.g. on at least one monitor. Furthermore, the user interface 23 has an input unit 25, by means of which information and/or parameters can be input by a medical operator during the measurement process.
Furthermore, the magnetic resonance apparatus 10 has a housing unit 100 which encloses the scanner unit 11. The housing unit 100 has a plurality of housing elements 101, 102 and/or housing shells. The first housing element 101 of the housing unit 100 here comprises a casing 103 which surrounds the patient accommodation region 12. In the present exemplary embodiment, the housing 103 surrounding the patient receiving area 12 is formed in one piece and/or integrally with the radio-frequency antenna unit 20, in particular the side of the radio-frequency antenna unit 20 facing the patient receiving area 12. Alternatively, the housing 103 surrounding the patient receiving area 12 may also comprise a housing element 101 which is formed separately from the radio-frequency antenna unit 20. The other housing element 102 of the housing unit 100 comprises a housing element 102 adjoining a housing 103. In the present exemplary embodiment, the housing element 102 adjoining the housing 103 has a housing element 102 which surrounds the inlet opening 26 of the patient receiving region 12, the housing element 102 being formed by a funnel element. In principle, however, the housing element 102 adjoining the housing 103 can have a different design than the funnel element.
The housing unit 100 also has at least one sealing element 104, which sealing element 104 is arranged between the housing 103 surrounding the patient receiving area 12 and the housing element 102, in particular a funnel element, adjoining the housing 103. In particular, the at least one sealing element 104 of the housing unit 100 is arranged in a transition region of the housing unit 100 between the housing 103 surrounding the patient receiving region 12 and the housing element 102 adjoining the housing 103.
The illustrated magnetic resonance apparatus 10 can of course comprise further components which are typical of the magnetic resonance apparatus 10. Furthermore, the general operation of the magnetic resonance apparatus 10 is known to the person skilled in the art, so that further components are not described in detail.
Fig. 2 shows the housing unit 100 with at least one sealing element 104 in detail, in particular a transition region 105 from a housing 103 surrounding the patient receiving region 12 to a housing element 102 adjoining the housing 103, in particular a funnel element. In the present exemplary embodiment, the housing unit 100 has a single sealing element 104, which sealing element 104 is designed as a sealing ring. The diameter of the sealing element 104, in particular of the sealing ring, corresponds here to the diameter of the housing 103 surrounding the patient receiving area 12. In particular, the inner diameter of the sealing element 104, in particular of the sealing ring, corresponds to the inner diameter of the housing 103 surrounding the patient receiving area 12.
In an alternative embodiment of the invention, the housing unit 100 can also have more than one sealing element 104. For example, the individual sealing elements 104, preferably the sealing elements 104 of the same type, can be arranged in succession in an annular seal between the housing 103 surrounding the patient receiving region 12 and the housing element 102, in particular a funnel element, adjoining the housing 103.
The sealing element 104 here has a light-resistant and/or wear-resistant material. For example, the material of the sealing element 104 may comprise silicone and/or silicone rubber and/or EPDM (ethylene propylene diene monomer) and/or TPE (thermoplastic elastomer) and/or other materials that appear to be of interest to those skilled in the art.
In order to arrange and/or fasten the sealing element 104 in the transition region 105, the sealing element 104 is arranged in a form-fitting and/or force-fitting and/or material-fitting manner on the housing element 102, in particular on the funnel element, adjacent to the housing 103. Here, the sealing element 104 can be bonded to the housing element 102, in particular the funnel element, adjacent to the housing 103, or can also be arranged and/or fastened on the housing element 102, in particular the funnel element, adjacent to the housing 103, due to static friction and/or adhesion forces and/or by means of locking elements or the like. In particular, the form-fitting and/or force-fitting and/or material-fitting arrangement and/or connection of the sealing element 104 to the housing element 102, in particular the funnel element, adjacent to the housing 103 is designed such that the housing element 102, in particular the funnel element, adjacent to the housing 103 can be mounted and/or arranged on the housing 103 together with the sealing element 204 as a structural unit.
In the present exemplary embodiment, the sealing element 104 has a recess 106, the recess 106 being provided on the side of the sealing element 104 facing the housing element 102 adjoining the housing 103, in particular the funnel element. The recess 106 of the sealing element 104 is open on the side facing the housing element 102 adjoining the housing 103, in particular the funnel element, and is bounded laterally by in each case one leg element 107 of the sealing element 104. Furthermore, the recess 106 is of conical and/or truncated-cone shape, wherein the width of the recess 106 on the side facing the housing element 102 adjoining the housing 103, in particular the funnel element, is greater than the width of the recess 106 on the side of the recess 106 facing the housing 103.
Furthermore, the housing element 102 adjoining the housing 103, in particular the funnel element, also has a projection 108 and/or a web-shaped element, wherein the recess 106 of the sealing element 104 and the projection 108 of the housing element 102 adjoining the housing 103, in particular the funnel element, are formed to correspond to one another. In particular, the projection 108 is conical and/or frustoconical. The width of the recess 106 of the sealing element 104 corresponds here to the width of the housing element 102 adjoining the housing 103, in particular the projection 108 of the funnel element. Furthermore, the length of the recess 106 of the sealing element 104 also corresponds to the length of the housing element 102 adjoining the housing 103, in particular the projection 108 of the funnel element. The recess 106 of the sealing element 104 therefore cooperates with the projection 108 of the housing element 102, in particular of the funnel element, adjacent to the housing 103 in an exact fit, so that the sealing element 104 is prevented from sliding off the housing element 102, in particular of the funnel element, adjacent to the housing 103 due to friction and/or adhesion forces.
In an alternative embodiment of the housing unit 100, the sealing element 104 can also be formed in one piece and/or in one piece with the housing element 102 adjoining the housing 103, in particular a funnel element. For example, the sealing element 104 can be arranged directly on the housing element 102, in particular on the funnel element, adjacent to the housing 103 in the injection molding process.
For the arrangement at the housing 103 surrounding the patient receiving area 12, the sealing element 104 has an edge region 110 covering the housing 103 and/or an overlap region 109 abutting against the edge region 110. The edge region 110 is arranged at the side of the housing 103 facing the housing element 102 adjoining the housing 103, in particular the funnel element. The edge region 110 has a recess 111. The recess 111 is provided at a side of the housing 103 facing the patient accommodation region 12. In the present embodiment, the vacant section 111 forms a step with respect to the surface of the housing 103 facing the patient accommodating area 12. The height of the recess 111, in particular of the step, of the housing 103 corresponds here to the thickness 112 of the overlapping region 109 of the sealing element 104.
The sealing element 104 is formed in a stepped manner on the side facing the housing 103. The thickness 112 of the overlap region 109 is smaller than the thickness 113 of the sealing element 104 before the step. Furthermore, the step and/or the overlap region 109 is formed tapered, wherein the sealing element 104, in particular the end of the overlap region 109, has the minimum thickness of the sealing element 104.
The overlap region 109 of the sealing element 104 is designed in such a way that, after the sealing element 104 has been installed between the housing 103 and the housing element 102, in particular a funnel element, adjacent to the housing 103, it rests under pretension against an edge region 110 of the housing 103. Furthermore, the housing 103, the sealing element 104 and the housing element 102 adjoining the housing 103, in particular the funnel element, form a planar and/or flat surface facing the patient accommodation region 12. Here, the overlap region 109 is provided at the following sides of the sealing element 104: the side is opposite to the side where the clearance 106 of the sealing element 104 is provided.
In an alternative embodiment of the sealing element 104 and of the housing 103 surrounding the patient receiving area 12, the housing can be formed without a recess 111. In this embodiment of the housing 103, the sealing element 104 also has no step. Here, the sealing element 104 will abut against the housing 103 on the side facing the housing element 102 adjoining the housing 103, in particular the funnel element, without the sealing element 104 overlapping the housing 103.
An alternative embodiment of the housing unit 200 is shown in fig. 3. Components, features and functions which remain substantially the same are in principle numbered with the same reference numerals. The description below is essentially limited to the differences from the exemplary embodiment in fig. 1 and 2, reference being made to the description of the exemplary embodiment in fig. 1 and 2 with regard to components, features and functions that remain unchanged.
The housing unit 200 in fig. 3 likewise has a housing element 201, which housing element 201 has a casing 202 which surrounds the patient receiving area 12. Furthermore, the housing unit 200 has a further housing element 203, which further housing element 203 is formed adjacent to the outer shell 202 and in particular comprises a funnel element of the housing unit 200. The housing element 203, in particular the funnel element, adjacent to the housing 202 encloses the inlet opening of the patient accommodation region 12. The housing unit 200 likewise has a sealing element 204, which sealing element 204 is arranged between the housing 202 surrounding the patient receiving area 12 and a housing element 203, in particular a funnel element, adjoining the housing 202. In particular, the sealing element 204 of the housing unit 200 is arranged in a transition region 205 of the housing unit 200 from the housing 202 surrounding the patient receiving region 12 to the housing element 203 adjoining the housing 202.
In order to arrange the sealing element 204 adjacent to the housing element 203 of the housing 202, in particular the funnel element, the housing element 203 adjacent to the housing 202, in particular the funnel element, has a recess 205. The recess 205 is formed cylindrically. Furthermore, the sealing element 204 has a web-shaped element 206 formed in a zigzag manner. The length and width of the web-shaped element 206 are designed to correspond to the length and width of the housing element 203 adjoining the housing 202, in particular the recess 205 of the funnel element. In particular, the length and width of the web-shaped element 206 of the sealing element are adapted to the length and width of the clearance 205. The web-shaped element 206 of the sealing element 204 thus cooperates with the recess 205 of the housing element 203, in particular of the funnel element, adjoining the housing 202 in a precisely fitting manner, so that the sealing element 204 is prevented from sliding off the housing element 203, in particular of the funnel element, adjoining the housing 202 due to friction and/or adhesion forces.
In contrast, the embodiment of the arrangement of the sealing element 204 at the housing 202 corresponds to the embodiment of fig. 2 referred to here.
Although the details of the invention have been illustrated and described in detail with respect to preferred embodiments, the invention is not limited by the disclosed examples and other variants can be derived therefrom by the person skilled in the art without departing from the scope of the invention.
