Description

[Technical field]

[0001] The present invention relates to an electrical medical device equipped with an antenna for wireless communication. [Background technology]

[0002] [Background of the invention] Due to the increasing requirements for traceability and documentation in healthcare in the course of digitalization, medical devices are communicatively configured or connected to communication devices that send and receive data from the medical device. The communication devices may be configured as wireless communication devices, which allows such medical devices to be used flexibly and to communicate and exchange data with other individual devices, device systems, and even hospital information systems in the same environment, as well as external IT systems (e.g. servers, clouds, etc.).

[0003] EMC (Electromagnetic Compatibility) regulations place high demands on electrical medical equipment (EME) in terms of emissions and immunity in order to ensure a safe and reliable operation of the equipment. For this purpose, electrical medical equipment (EME) is constructed with "radio-impermeable" or EMC-certified (electromagnetic wave-resistant) equipment housings.

[0004] One example of such a regulation is the EN 60601-1-2:2015+A1:2021 standard, which specifies EMC requirements for medical electrical equipment.

[0005] [Cutting-edge technology] To enable wireless communication, the state of the art provides for an external connection of a wireless antenna of a communication device to the medical device, for example, the state of the art provides for an antenna to be attached to an antenna connector configured for the antenna on the device housing, or an external communication device to be connected to the medical device via a cable.

[0006] A drawback of the prior art is that externally accessible antennas can be forgotten, especially during preparation for surgery. Furthermore, during transportation of the medical device, such antennas can be damaged or broken by protruding from the device housing. Another drawback is that externally accessible antennas create edges and joints that are difficult to clean (potential breeding grounds for germs and bacteria), which can pose a risk to the health and safety of patients, especially in a surgical environment.

[0007] In principle, it is possible to provide an additional compartment on the outside of the housing to accommodate the antenna. It is also possible to extend one side of the housing and create an internal compartment for the antenna. This would solve the above problem, but would increase the overall dimensions of the device. Furthermore, this would increase the manufacturing effort and therefore the manufacturing costs.

[0008] It is therefore an object of the present invention to eliminate or at least mitigate the drawbacks of the prior art, in particular to provide an electrical medical device, in particular a tabletop medical device, that meets the requirements of EMC regulations without the drawbacks of externally connected antennas and / or problems resulting from increased housing dimensions. Summary of the Invention

[0009] This object is solved by an electromedical device in the form of a tabletop unit according to independent claim 1. Advantageous further embodiments are part of the dependent claims.

[0010] The basic idea of ​​the invention is to identify a location within the housing of an electrical medical device, essentially in the form of a tabletop unit (e.g. an infusion pump, a syringe pump or similar device), which is suitable in terms of spatial conditions to accommodate one or more antennas, has little or no shielding from the outside, and is shieldable or shielded from the rest of the housing space.

[0011] In other words, the idea of ​​the invention is to shield from the inside areas of an existing housing that are not or poorly shielded from the outside, and to equip such a shielded housing area with at least one antenna for data communication to the outside of the housing, which may be wired to an electronic device in the housing, which is outside of said area and therefore shielded from the at least one antenna.

[0012] As a result, it has been found that the front plate of the housing of such medical devices (medical devices), for example in the form of a tabletop device (unit), is usually provided with display elements (display section) and / or operating elements (operating section), and therefore has little or no shielding effect at least in these areas. This means that a compartment (storage section) isolated from the rest of the space inside the housing by shielding is destined to accommodate at least one antenna immediately behind (on the back side) of the front plate of such a housing. Parts (parts) of the housing may also protrude from the side wall (side part) or the rear wall (rear part, rear plate), and these parts (parts) may be located outside the shielding member (electromagnetic wave shield) inside the housing. In this case, such protruding housing parts (parts) may be used to accommodate at least one antenna.

[0013] In particular, the object of the present invention is solved by a medical device or apparatus in the form of a tabletop appliance (unit) comprising a housing with a front plate and / or a rear plate and a wireless communication unit with at least one antenna constructed or arranged in said housing, said housing having at least one substantially EMC-secure housing part (wherein the communication unit is arranged except for the antenna) and at least one non-EMC housing part (electromagnetically transparent housing part), said at least one antenna of said wireless communication unit constructed or arranged in said at least one non-EMC (electromagnetically transparent) housing part of said housing.

[0014] It should be noted that a tabletop unit may be understood to refer to a medical device with a closed housing suitable for operation on a surface such as a table, for insertion or placement in a rack, etc. Tabletop units may be, for example, motor controllers, pumps, etc., operated individually or as a group in a rack.

[0015] In other words, the medical device in the form of a tabletop device (unit) has a housing, preferably of a rectangular parallelepiped shape, with a front plate facing the operator and / or a rear plate facing away from the operator. The wireless communication unit and at least one antenna connected to the wireless communication unit (as its functional parts) are constructed or arranged in the housing. Furthermore, (electrical) components essential for the functioning of the medical device are constructed or arranged in the housing. The housing comprises (spatially) at least one EMC-certified housing part, for example made of a metal part or a metallized plastic part. EMC-certified here means that electromagnetic waves (for example light or high-energy microwaves) cannot pass through the EMC-certified housing part. Furthermore, metallized plastic part means both plastic parts coated with a metal layer and plastic parts that contain metal particles incorporated in the plastic. The components essential for the functioning of the medical device are preferably spatially surrounded by at least one EMC-certified housing part. In addition to at least one EMC-secured (electromagnetically resistant) housing part, the housing spatially comprises at least one non-EMC (electromagnetically transparent) housing part. Non-EMC (electromagnetically transparent) in this context means that electromagnetic waves (particularly radio waves) can pass through the non-EMC (electromagnetically transparent) housing part. The radio waves can be Bluetooth according to the IEEE 802.11 standard, WLAN (wireless network) or any other type of radio waves arranged to transmit data wirelessly. An antenna connected by a cable to the wireless communication unit is provided and arranged to receive and / or transmit the radio waves. The antenna is arranged inside the housing and adjacent to the non-EMC (electromagnetically transparent) housing part.

[0016] By forming the housing to comprise at least one non-EMC (electromagnetically transparent) housing part, the EMC-related components can be reliably protected from electromagnetic radiation and thus protected from malfunction due to electromagnetic radiation.

[0017] By arranging the at least one antenna inside the housing, the housing can be configured to have as flat a surface as possible, avoiding the formation of beads or edges on which dirt, germs and bacteria can adhere and grow, and also preventing the antenna from being damaged or forgotten, for example before the start of an operation. A reliable functioning of the wireless communication unit can be ensured, since the at least one antenna is provided in at least one non-EMC (electromagnetically transparent) housing part.

[0018] Therefore, the essence of the present invention is to form a tabletop electrical medical device having both at least one non-EMC (electromagnetically transparent) housing part and at least one EMC-guaranteed (electromagnetically resistant) housing part, and at least one antenna of a wireless communication unit is arranged within the at least one non-EMC (electromagnetically transparent) housing part.

[0019] In the first aspect, the at least one antenna may be shielded by a shielding sheet (electromagnetic wave shield) in a direction toward the inside of the housing.

[0020] In other words, the at least one antenna may be surrounded by a shielding sheet and a non-EMC (electromagnetically transparent) housing part, whereby the shielding sheet shields the at least one antenna from the inside of the housing. The shielding sheet may be made of a metal part or a metallized plastic part.

[0021] The shielding sheet can prevent electromagnetic radiation from the environment surrounding the medical device from penetrating the interior of the housing through the at least one non-EMC (electromagnetically transparent) housing part and the at least one antenna, thereby limiting or disrupting the function of components essential to the function of the medical device, thereby endangering the safety of the patient. Furthermore, it can also prevent electromagnetic radiation emitted from the at least one antenna from penetrating the interior of the housing, thereby limiting or disrupting the function of components essential to the function of the medical device, thereby endangering the safety of the patient.

[0022] In a further aspect, the at least one antenna and the wireless communication unit may be connected to each other by a cable that is guided through a hole in the shielding sheet.

[0023] In other words, the shielding sheet may be provided with cable passages in the form of holes, the diameter of which may substantially correspond to the diameter of the cables, or alternatively, the diameter of the holes may be slightly larger than the diameter of the cables.

[0024] This construction of the cable guide ensures that the EMC shielding provided by the cable guide is impermeable to electromagnetic waves, which ensures that the functioning of critical components of the medical device is not restricted or interrupted.

[0025] In a further aspect, the at least one non-EMC (electromagnetically transparent) housing part is provided in a frame (frame structure) of the housing, and preferably the at least one antenna is provided in a frame recess (frame recess) of the frame.

[0026] In other words, the housing may have the frame at a number of (outer) edges of the housing. In particular, the frame may be arranged to protrude outward from the housing. The frame may be made entirely or partly of a non-EMC (electromagnetically transparent) material, which may form a non-EMC (electromagnetically transparent) housing part. The frame may preferably have a frame recess arranged to match the shape of an antenna. The frame recess is arranged and configured to accommodate the at least one antenna. The frame may be arranged only in the frame recess of the non-EMC (electromagnetically transparent) housing part.

[0027] By providing the frame with a non-EMC (electromagnetically transparent) housing part, the manufacturing costs of the housing can be reduced. Furthermore, in this way, the at least one antenna can be arranged in a favorable position for transmitting and receiving radio waves. By providing a frame recess, the at least one antenna can be fixed in a form-fitting manner in the frame or in the non-EMC (electromagnetically transparent) housing part. This prevents the at least one antenna from sliding around and ensures constant receiving and transmitting power.

[0028] In a further aspect, the medical device in the form of a tabletop device (unit) may be provided with a display unit, preferably in the form of a screen, in the front plate, and said at least one antenna may be constructed and arranged on the inner surface of the front plate facing the inside of the housing.

[0029] In other words, the at least one antenna may be provided on the rear surface (back surface) of the front plate. Preferably, the at least one antenna may be provided on the rear surface (back surface) of the display unit.

[0030] When a medical device in the form of a tabletop device (unit) is used in daily hospital life, the medical device is usually placed so that the front plate including the display unit faces the center of the room so that the user can easily read the contents output via the display unit (if the display unit is a touch screen, so that the user can configure the medical device settings). Therefore, when the at least one antenna is provided on the front plate, it is ensured that the antenna is placed as far as possible in the direction toward the center of the room, thereby improving the receiving power and transmitting power of the antenna (and thus the wireless communication unit).

[0031] In a further embodiment, the face plate may be made of glass and the at least one antenna may be secured to the face plate by adhesive.

[0032] In other words, the front plate may be made of glass material, especially in the area of ​​the display unit and / or in the area where the at least one antenna is fixed to the front plate, and the at least one antenna may be glued to the front plate, preferably over a large area.

[0033] Since glass is a material through which radio waves can pass, reception and transmission performance can be improved. By bonding the at least one antenna to the front plate, it can be ensured that the at least one antenna does not move from a predetermined antenna position.

[0034] In a further aspect, the at least one antenna may be provided in a front frame portion of the frame, preferably in the frame recess, below the front plate.

[0035] In other words, the frame may include a front frame portion disposed below the front plate, and the at least one antenna may be provided on the front frame portion disposed substantially on a plane of the bottom surface of the medical device.

[0036] When using a medical device in the form of a tabletop device (unit), the medical device is usually arranged so that the front plate including the display unit faces the center of the room so that the user can easily read the contents output via the display unit. When the at least one antenna is provided on the front frame part below the front plate, it is ensured that the antenna is arranged as far as possible in the direction toward the center of the room, which improves the reception and transmission performance. Furthermore, such an arrangement of the at least one antenna ensures that the housing part made of a non-EMC (electromagnetically transparent) material is arranged as far as possible from components essential to the functioning of the medical device.

[0037] In a further aspect, the at least one antenna may be configured in a planar (strip) shape and may be arranged to extend substantially perpendicular to the front plate.

[0038] In other words, the at least one antenna may be oriented substantially parallel to the base portion. Such an arrangement allows the medical device to be as compact as possible.

[0039] In a further embodiment, the at least one antenna may be provided in a rear frame portion of the frame (provided to border the rear portion of the housing on the side opposite to the front plate), preferably in the frame recess, and the rear frame portion may be provided at a greater distance from the front plate than the rear portion (the distance from the front plate to the rear frame portion may be greater than the distance from the front plate to the rear portion).

[0040] In other words, the rear frame portion may at least partially surround the rear face of the housing and may protrude from the rear face in a direction perpendicular to the rear face such that the rear frame portion forms the housing portion furthest from the front plate. A frame recess for accommodating the at least one antenna may optionally be provided in the rear frame portion. Preferably, the rear frame portion may be formed in a U-shape that opens towards the cover plate (top face) of the medical device.

[0041] By providing the at least one antenna on a rear frame portion protruding from the housing, the reception and transmission performance of the at least one antenna can be improved. In particular, the protruding portion of the rear frame portion can prevent or at least reduce degradation of reception and transmission performance caused by the housing itself.

[0042] In a further aspect, the at least one antenna may be configured in a planar (strip) shape and may be disposed generally parallel to the front plate.

[0043] In a further embodiment, the medical device may be provided with at least two antennas, and the two antennas may be oriented at a 90° angle to each other.

[0044] Such an arrangement may maximize the radiation area occupied by the two antennas.

[0045] In a further embodiment, the at least two antennas may be located in different (separate) non-EMC (electromagnetically transparent) housing parts, for example, a first antenna may be located on the underside of the front plate and a second antenna may be located on a rear frame part protruding from the housing.

[0046] In a further aspect, multiple antennas may be provided within the housing.

[0047] In a further embodiment, the at least one non-EMC (electromagnetic wave transparent) housing portion of the housing may be smaller than the at least one EMC-secured (electromagnetic wave resistant) housing portion of the housing.

[0048] In a further embodiment, the overall size of all non-EMC (electromagnetic wave transparent) housing parts of the housing may be smaller than the overall size of all EMC secured (electromagnetic wave resistant) housing parts of the housing.

[0049] In further embodiments, the data transferred via the at least one antenna and communication unit may be statistics, control programs, treatment protocols, and the like.

[0050] In a further aspect, the at least one antenna may be a wireless LAN antenna.

[0051] In a further aspect, the at least one antenna may be a Bluetooth antenna.

[0052] In a further aspect, the at least one antenna may be a mobile radio antenna.

[0053] In a further aspect, the frame may be made from plastic.

[0054] In a further embodiment, the at least one antenna may be provided on the front plate above the display unit.

[0055] In a further embodiment, a benchtop medical device may be provided with at least two antennas.

[0056] In a further embodiment, the two antennas may be oriented at a 90° angle to each other.

[0057] In a further embodiment, the at least two antennas may be arranged in different (preferably spaced apart) non-EMC (electromagnetically transparent) housing parts.

[0058] In a further aspect, the housing may have a bottom surface that defines a mounting area for the medical device for tabletop use.

[0059] In a further aspect, the housing may have a cover plate, and the front plate may be disposed so as to straddle the cover plate (top portion) and the bottom portion. [Brief description of the drawings]

[0061] Hereinafter, configuration examples of the present invention will be described with reference to the associated drawings.

[0062] FIG. 1 shows an electric medical device (medical device 1) for tabletop use. The medical device 1 includes a housing 3 and is configured in the form of a motor control device for driving and controlling, for example, a medical drill. The housing 3 has a substantially rectangular parallelepiped shape and includes a cover plate 5 on the upper surface, a bottom portion 7 on the lower surface, two side walls 9, a rear portion 11, and a front plate 13. The two side walls 9, the rear portion 11, and the front plate 13 are arranged to substantially straddle between the cover plate 5 and the bottom portion 7. The front plate 13 is provided with a terminal 15, a function button 17, and a screen (display portion) 19. A frame structure 21 is provided at an edge portion of the housing 3. The edge portion of the housing 3 here can be understood as a transition portion between the cover plate 5, the side walls 9, the rear portion 11, the front plate 13, and the bottom portion 7. The bottom portion 7 forms the installation area of ​​the medical device 1. The two side walls 9 and the rear surface 11 are oriented (disposed) substantially perpendicular to the cover plate 5 and the bottom surface 7 .

[0063] The housing 3 is substantially made of an EMC countermeasure material (EMC guaranteed material, electromagnetic wave resistant material). For example, metal or metallized plastic (TSG material) can be used as the EMC countermeasure material. The frame structure 21 has electromagnetic wave transparency (EMC incompatibility) in a predetermined area. This means that the frame structure 21 is not metallized or is not made of metal in the predetermined area.

[0064] 2 shows the medical device 1 in the first embodiment in a first cross section along the height direction of the medical device 1. The height direction here can be understood as the direction extending between the bottom part 7 and the cover plate 5. The first cross section is arranged parallel to the two side walls 9.

[0065] The screen 19 is recessed in the front plate 13. The front plate 13 is angled (slanted) to improve the readability of the screen 19. In other words, the front plate 13 is oriented at a (slightly) oblique angle with respect to the normal of the cover plate 5 and the base part 7.

[0066] Electrical components 23 essential for the function of the medical device 1 are disposed in an internal space surrounded by the housing 3. The housing 3 of the medical device 1 is EMC-proof (EMC-certified) (has electromagnetic wave resistance) and therefore protects the electrical components 23 from influence or interference due to electromagnetic interference from the environment surrounding the medical device. On the other hand, the housing 3 with EMC protection (EMC-certified) also prevents electromagnetic interference (electromagnetic wave emission) from the electrical components 23 to the surrounding environment.

[0067] The medical device 1 further includes a wireless communication module (wireless communication unit) 25 (see FIG. 3 or FIG. 4). The wireless communication module 25 is provided and configured to wirelessly exchange (transfer) data between the medical device 1 (particularly, the electrical components 23 of the medical device 1) and individual devices, device systems, hospital information systems, and external IT systems (e.g., clouds, online connections to device manufacturers, etc.) arranged in the environment surrounding the medical device 1 via an antenna 27. The wireless communication module 25 is connected to the antenna 27 via a cable (not shown). In the first embodiment shown in FIG. 2, the antenna 27 is arranged in the frame structure 21 below the screen 19. In other words, in the first embodiment, the antenna 27 is arranged in the frame recessed portion approximately parallel to the bottom surface portion 7. The frame recessed portion here is an empty space in the frame structure 21. In a direction away from the inside of the medical device 1, the antenna 27 is restricted (compartmented) only by the frame structure 21. The frame structure 21 is permeable to electromagnetic radiation, particularly radio waves emitted from the antenna 27. In the direction toward the inside of the medical device 1, the antenna 27 is shielded by a shielding sheet (electromagnetic wave shielding sheet) 29. The shielding sheet 29 also ensures EMC protection of the electrical component 23 against electromagnetic waves passing through the area in which the antenna 27 is provided.

[0068] FIG. 3 shows the electric medical device (medical device 1) in the first embodiment in a second cross section along a direction parallel to the bottom surface portion 7. The wireless communication module 25 is screwed to the main board 31 inside the medical device 1 perpendicularly to the main board 31. A power plug 33 is provided on the rear surface portion 11. The power plug 33 is connected to the main board 31 and supplies electric energy to the electric components 23 and the wireless communication module 25. The two antennas 27 in the first embodiment shown in FIG. 3 are provided in the frame structure 21 of the front plate 13 below the screen 19, at positions as far away as possible from the inside of the medical device 1. In this way, the antennas 27 can ensure the largest possible radiation area. The two antennas 27 are bonded to the frame structure 21. In the first embodiment shown in FIG. 3, the two antennas 27 are arranged approximately symmetrically with respect to the center of the front plate 13.

[0069] FIG. 4 shows a perspective view of an electric medical device (medical device 1) in the second embodiment. In FIG. 4, the cover plate 5 is removed for ease of explanation. The two antennas 27 are attached to the back surface (rear surface) of the front plate 13. The back surface (rear surface) of the front plate 13 here refers to the surface of the front plate 13 facing the inside of the medical device 1. The antennas 27 are attached to the back surface of the front plate 13 via an adhesive. The front plate 13 is made of, for example, glass. This allows the front plate 13 to transmit electromagnetic radiation (particularly radio waves) received and transmitted by the antennas 27. In the second embodiment, the antennas 27 are also shielded by a shielding sheet in the direction toward the inside of the medical device 1. However, in FIG. 4, the shielding sheet is not shown in order to simplify the drawing.

[0070] Two antennas 27 are fixed to the rear surface of the front plate 13 so as to extend at an angle of 90° to each other.

[0071] FIG. 5 shows an electric medical device (medical device 1) in the third embodiment in a cross section along a direction parallel to the side wall 9. More specifically, FIG. 5 is an enlarged cross-sectional view showing the rear part of the medical device 1 near the rear part 11. The frame structure 21 protrudes from the medical device 1 along a direction perpendicular to the rear part 11. The frame structure 21 borders the rear part 11 in a U-shape. The frame structure 21 is provided with a frame recess. The frame recess accommodates the antenna 27 between the frame structure 21, which transmits electromagnetic waves (particularly, the radio waves of the antenna 27), and the shielding sheet 29, which does not transmit electromagnetic waves (particularly, the radio waves of the antenna 27). The antenna 27 is provided at a position exposed to the rear part 11 (a position outside the rear part 11).

[0072] 6 shows the electric medical device (medical device 1) in the third embodiment with the frame structure 21 and the cover plate 5 removed. The antenna 27 is arranged to extend substantially parallel to the bottom part 7. The antenna 27 is bonded to a shielding sheet 29. More specifically, the antenna 27 is bonded to a surface (outer surface) of the shielding sheet 29 opposite to the interior of the medical device 1. The shielding sheet 29 is provided with, for example, a plurality of cable passages (holes) 35. This allows a cable connecting the antenna 27 to the wireless communication module (wireless communication unit) 25 to be routed (guided) through the cable passage 35 without compromising the EMC protection of the electrical components 23 arranged inside the medical device 1.

[0073] In an alternative embodiment not shown, the antenna may be mounted on a frame structure between the side wall and the cover plate.

[0074] In an alternative embodiment not shown, the antenna may be mounted above the screen (display) on the front plate.

[0075] The embodiments described above can be combined with each other in any combination. [Explanation of symbols]
