Description

[Technical Field]

[0001] In various embodiments of the invention, the invention relates to the structure of a dental treatment unit used in dental treatment work, in particular to a cover structure of the dental treatment unit and to solutions used for the structure below this cover structure, and also to controlling the dental treatment unit and to a dental treatment room or premises having a dental treatment unit according to the invention. [Background technology]

[0002] In the field of dentistry, the term dental treatment unit (often simply "dental unit") refers to an apparatus or arrangement that supplies electrical power, and sometimes control signals, to equipment used in connection with dental treatment operations, and sometimes to various other devices used in connection with dental treatment operations.

[0003] One common solution used in dental treatment units is to place dental treatment instruments on an instrument console supported by support arms that extend from the frame structure of the dental treatment unit. Dental treatment units can have two or more different support arms, for example, for dental assistant's instruments or other devices used in connection with the dental treatment operation.

[0004] One common solution used in dental treatment units is to arrange one or more horizontal support arms on a support device that extends vertically from the frame portion of the dental treatment unit. Such devices are generally implemented to have a specific number of support arms or to allow for a specific number of different arm assembly variations, which can be implemented when the dental treatment unit is initially assembled or as a later retrofit. Such vertical support devices are generally connected to a cover structure on the frame portion of the dental treatment unit.

[0005] Since individual dentists, as well as dentists in different dental clinics, educational facilities, and different cultures, have different needs and desires when it comes to equipping dental treatment units with instruments, accessories, and support arm solutions to suit their needs, it has become a challenge for dental treatment unit manufacturers to continue to design and offer different dental treatment unit versions. Summary of the Invention

[0006] It is an object of the present invention to provide a dental treatment unit in which the frame structure is implemented in such a way that vertically extending support structures commonly used in dental treatment units can be reasonably easily attached or modified to (or detached from) the frame structure in the field. It is an object of some preferred embodiments of the present invention to implement a frame structure that simultaneously provides new functionality to the dental treatment unit.

[0007] The features of the invention are defined in the attached independent claims: In a dental treatment unit according to the invention, essentially the cover structure has at least two parts, preferably realised in such a way that by removing a cover part removably connected to the cover structure, access to the structure below the cover structure is provided, while the possibility of opening the cover structure also facilitates the installation and replacement of another pole extending vertically through the cover structure. [Brief explanation of the drawings]

[Figure 7] FIG. 1 is a diagram schematically illustrating a configuration for controlling lighting arranged in a dental treatment unit. [Figure 8] FIG. 1 shows a dental treatment room or dental treatment facility equipped with a dental treatment unit according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0009] Figure 1 shows the basic structure of one typical dental treatment unit 1 intended for use in connection with dental treatment operations. The dental treatment unit 1 of Figure 1 comprises a frame portion 2 and a patient chair 3 connected thereto. Extending vertically from the frame portion 2 is a support device 4. The support device 4 comprises a vertically extending support portion 41, a first support structure 42 for supporting diagnostic instruments related to the dental treatment and / or instruments 6 used in connection with the dental treatment operation, a second support structure 43 for, for example, a surgical lamp 8 or an X-ray means used in connection with the dental treatment operation, and a third support structure 44 for, for example, a display 10.

[0010] 1 further shows an instrument holder 11 that can be configured to support instruments typically used by a dental assistant, and a foot control 12 that can control the functions of the dental treatment unit 1 and / or devices or structures connected or coupled thereto. Additionally, the dental treatment unit 1 is configured for operational connection with a data network or a separate computer 13.

[0011] It should be noted that the dental treatment unit of FIG. 1 is merely an example. Within the scope of the present invention, a dental treatment unit may have more or fewer support structures than those included in the structure of FIG. 1 , depending on the device. Also, for example, the patient chair need not necessarily be integrated with the dental treatment unit but can be realized as a structure completely separate from the dental treatment unit. On the other hand, the frame structure can be configured as an integral part of the floor-mounted chair structure. Furthermore, instead of a structure with significant horizontal and vertical dimensions as shown in FIG. 1 , the dental treatment unit frame structure can be primarily a small structure with one or more support arms extending therefrom. Along with or in addition to a foot control, the device can also include a graphical interface or other user interface. However, the structure of the dental treatment unit according to the present invention is realized so as to transmit or be configured to transmit power, fluids, and / or control signals necessary to operate the instruments and devices used in a dental treatment operation. Physically, this therefore means transmitting at least one of, for example, water, compressed air, electricity, and control signals.

[0012] Therefore, in the context of this application, when a dental treatment unit is mentioned, it refers to a structure including configurations that enable at least one of the above or corresponding variables to be supplied to dental treatment instruments and / or devices used in connection with dental treatment work operations that are configured in connection with the dental treatment unit.

[0013] Thus, the dental treatment unit of Figure 1 is an example of a typical dental treatment unit according to the prior art. The frame structure of the dental treatment unit of Figure 1 has a one-piece molded cover part that completely, or practically completely, covers the frame structure of the dental treatment unit.

[0014] 2-6 show a collection of solutions according to various embodiments of the present invention for use in relation to a cover structure of a frame part of a dental treatment unit and on the other hand in a structure below the cover structure.

[0015] 2 and 3 show an example of a cover structure 22 of a dental treatment unit according to the present invention. The cover structure 22 is formed by a first cover part 22′ and a second cover part 22″, with a seam locus 23 formed between these cover parts 22′, 22″. These cover parts 22′, 22″ together cover the vertically extending wall structure 21 of the frame part 2. An opening 52 is formed between the first cover part 22′ and the second cover part 22″. In the embodiment of FIGS. 2 and 3, this is a substantially circular opening 52, which is formed by adjacent semicircular notches 52′, 52″ provided in the first cover part 22′ and the second cover part 22″. In FIG. 2, the opening 52 in the cover structure 22 is closed by a closing disk 51. Such a closure disc 51 may be configured to close the opening 52 in embodiments in which the vertically extending support portion 41 as shown in FIG. 1 is not configured to extend through the cover structure 22, but rather the frame portion 2 is simply provided with means for later mounting the vertically extending support portion 41.

[0016] The cover structure 22 according to the present invention has at least a first cover part 22' and a second cover part 22", of which, in the embodiment of Figures 2 and 3, the second cover part 22" is configured to be removably attached without the need to disassemble the entire cover structure 22. This solution offers a practical possibility for realizing the frame part 2 of a dental treatment unit in such a way that at least some of the structures and parts located within the frame part 2 are easily accessible from above. Naturally, such parts of the cover structure are each smaller and lighter than the entire cover structure 22 as a whole and are therefore easier to handle.

[0017] Realizing the cover structure 22 with two or more cover parts 22', 22" offers, inter alia, the possibility of facilitating the attachment of the support structure 4 having vertically extending support parts 41 to the frame structure 2 of the dental treatment unit. Thanks to the invention, the attachment device for the support structure 4 can be realized in such a way that it is relatively easy to later replace the support structure 4 with another one or to install it in the dental treatment unit, when necessary.

[0018] Figure 3 shows the structure of the frame part 2 of the dental treatment unit with the second cover part 22" removed. On the one hand, Figure 3 shows a more detailed view of the sealing element 24 arranged at the seam position 23, and on the other hand, the support plate 53 located below the cover structure 22 and vertically spaced below it, and the structure arranged thereon. This structure has, in the embodiment of Figure 3, guide holes 57 (in Figures 3 to 5, for the sake of clarity, only one of these holes is mentioned in each figure). In the guide holes 57, for example, a mounting pin (not shown in the drawings) that is integrated with the second cover part 22" and points vertically downwards can be arranged so as to allow the second cover part 22" to be removably attached to the frame part 2.

[0019] 3 further shows a light device with two lights 55, 55'. The lights 55, 55' may have as light sources, for example, RGB LED components that can emit light in different colors.

[0020] 3 also shows the vertically extending support portion 41 as well as passages 56 disposed in the support plate 53 for wiring routed through the support plate 53 or the support portion 41. (To keep the drawings of this application clearer, the drawings do not show the tubes or cables that are the reason for disposing the passages 56 in the frame portion 2.)

[0021] The light device may have one or more light-emitting components 555 integrated into the sealing element 24 instead of or in addition to the lights 55, 55' arranged under the cover structure 22 (Figure 3 shows another embodiment of the sealing element 24).

[0022] In general, the number, structure, and operating principle of the parts of the light device 55, 55′ disposed under the cover structure 22 or the light-emitting components 555 integrated with the sealing element 24 can be varied within the scope of the present invention. However, in some embodiments of the present invention, the light device 55, 55′ and / or one or more light-emitting components 555 integrated with the sealing element 24 can preferably be controlled by the control system of the dental treatment unit to generate, for example, at least two different colors of light and / or differently pulsed light. In this context, “differently pulsed” includes, in one embodiment, pulses, which actually mean continuous generation of light.

[0023] In the embodiment of Figures 2 and 3, two separate sealing elements 24 arranged at the seam locations 23 and extending towards the outer periphery of the cover structure 22 are configured to limit the openings 52 provided for the vertical support portions 41 in these areas.

[0024] On the other hand, in one embodiment of the present invention, sealing element 24 can be configured to span cover structure 22 as a single continuous element, bifurcating into two at opening 52 in cover structure 22. Thus, in this embodiment, sealing element 24 can close the periphery of vertical support 41 located at opening 52.

[0025] In other embodiments of the present invention, the contour shape of the cover portion notches 52', 52" located at the seam location 23 between the first cover portion 22' and the second cover portion 22" can be other than the semicircular shape shown in Figures 2 and 3.

[0026] In extreme cases, the edges of the cover parts 22', 22" at the seam location 23 can even be straight along their entire length. In that case, the dimensions of the support part 41 extending vertically from the cover structure 22 will naturally be realized relative to the width of the seam location 23 formed between the cover parts 22', 22" and the width of the sealing element 24 arranged at the seam location 23 so that the vertically extending support part 41 fits into the seam location 23 between the first cover part 22' and the second cover part 22".

[0027] A preferred embodiment of the cover structure 22 can be considered to be a structure in which at least one of the first cover part 22′ and the second cover part 22″ belonging to the cover structure 22 has a cutout or opening 52 for receiving a vertically extending support part 41 connecting with the area of ​​at least one seam location 23 or with the seam location 23 itself.

[0028] The cutout or opening 52 may be formed by notches 52', 52'' in both the first cover portion 22' and the second cover portion 22'' adjacent the seam location 23.

[0029] The vertically extending support 41 attached to the dental treatment unit can be configured to extend through an opening 52 provided in the cover structure 22 in some of the ways described above.

[0030] In the embodiment shown in the accompanying drawings, the sealing element 24 is realized in two parts and in such a way that it does not extend completely around the vertically extending support 41. One solution is to cut the sealing element 24 described in relation to the above embodiment into two parts substantially at the location of the vertically extending support 41. This creates a structure in which the sealing element 24 surrounds the vertically extending support 41, but which is easier to assemble when considering the placement of the support structure 4. Alternatively, such a cut can be made on the sealing element 24 only on one side of the location where the vertically extending support 41 is located.

[0031] In one preferred embodiment of the present invention, the cover structure 22 has a shape that slopes downwards towards the periphery of the cover structure 22 in at least one area of ​​the seam location 23 .

[0032] In one preferred embodiment of the invention, the periphery of the cover structure 22 extends horizontally beyond the vertically extending wall structure 21 of the frame portion 2 at at least one seam location 23 .

[0033] In one preferred embodiment of the present invention, the cover structure 22 has a substantially vertically downwardly extending portion about its periphery at at least one seam location 23 .

[0034] In one preferred embodiment of the present invention, the cover structure 22 thus has a substantially horizontally extending surface at the seam location 23, for example a surface that slopes slightly downwards towards the periphery of the cover structure 22.

[0035] 2 and 3 show how the surface of the cover structure 22 is bent at its periphery so as to turn downwards and extend a short distance away from the vertically extending wall structure 21 of the frame part 2. In this case, the sealing element 24 may also be configured to bend accordingly and extend beyond the bending point of the cover structure 22.

[0036] In a preferred embodiment of the present invention, the cover structure 22 is divided into two cover sections 22', 22" such that the seam location 23 between these cover sections 22', 22" extends beyond the substantially horizontal surface of the cover structure 22 onto the vertical surface. In this case, the cover structure 22 can have a seam location 23 comprised of one or more sealing elements 24, for example, a configuration described in more detail below that allows for luminous seam locations 23 that extend beyond the substantially horizontal surface of the cover structure 22 onto both sides of the cover structure 22.

[0037] In the embodiment of Figures 2 and 3, the seal located at the seam location 23 is formed by two separate seal elements 24, both of which extend from the opening 52 between the cover portions 22', 22" onto the outer periphery of the cover portions 22', 22".

[0038] In one embodiment of the invention, the sealing element 24 extends toward the periphery of the cover structure 22 at at least one seam location 23 as much as the cover structure 22 extends.

[0039] In the embodiment of the invention of Figures 2 and 3, one seam location 23 extends beyond the cover structure 22, in connection with which an arrangement consisting of two sealing elements 24 is adapted. However, the seam location 23 can also be arranged on the cover structure 22 in a different way. There may be more than two seam locations 23. In this case, for example, the second cover part 22" according to the accompanying drawings can be further divided into two cover parts, so that the seam location formed between them extends over the periphery of the cover structure 22 in a direction substantially perpendicular to the seam location 23 between the first cover part 22' and the second cover part 22".

[0040] FIG. 4 shows a preferred embodiment of the structure of the sealing element 24. The sealing element 24 of FIG. 4 has two leakage grooves 26 configured to collect liquid that may drip at the seam location 23 of the cover parts 22′, 22″. The number of leakage grooves 26 may be other than two. The leakage grooves 26 are intended to protect structures and components below the cover structure 22 from getting wet or dirty.

[0041] When the cover structure 22 is configured to slope downward toward the outer periphery as described above, any liquid that may have entered the leakage groove 26 can flow by gravity through the leakage groove 26 first to the edge of the cover structure 22, and then to the outside of the vertically extending cover structure 21 of the frame portion 2 of the dental treatment unit.

[0042] The external shape of the sealing elements 24 does not necessarily have to be the same along their entire length, for example exactly the same as shown in Figure 4. For example, if a solution consisting of two sealing elements 24 as shown in Figure 3 is used, and each sealing element 24 is connected at its first end to an opening 52 provided in the cover structure 22 or to a vertical support part 41 located at the opening 52, the end of each sealing element 24 can be closed at its first end so that none of the leakage grooves 26 formed in the sealing elements 24 extend all the way to the opening 52. In this case, the one or more leakage grooves 26 each extend in an open manner, in particular in the direction of the outer periphery of the cover structure 22, preferably beyond the vertical wall 21 of the frame part 2 as shown in one of the above embodiments.

[0043] Thus, the cross-sectional profile of the sealing element 24 may have at least one leakage groove 26 along at least a portion of the length of the sealing element 24 .

[0044] In a preferred embodiment of the present invention, the sealing element 24 or sealing elements are made of an elastic material and are configured to conform to the shape of the cover portions 22', 22" at the seam location 23. However, the sealing element 24 can also be an elastic sealing strip that is placed to conform to the shape of the seam location 23 between the cover portions 22', 22" when assembling the cover structure 22.

[0045] Figures 5 and 6 show an example of some suitable internal structures of the dental treatment unit frame part 2. Compared to Figure 1, the support device 4 shown in Figure 5 includes only a part of the corresponding structure.

[0046] As shown in FIG. 6, the structure belonging to the frame part 2 includes, below the support plate 53, support pillars 50 supporting the support plate 53 and first connection means 54 configured to connect to the mounting device of the support structure 4. FIG. 5 shows a second connection means 54' belonging to the mounting device of the support structure 4 and arranged above the support plate 53. The connection means 54, 54' shown in FIGS. 5 and 6 have flanges on the upper and lower sides of the support plate 53. Of these, according to a preferred embodiment of the present invention, when the support structure 4 with the vertical supports 41 is not attached to the dental treatment unit, only the lower flange is arranged on the structure of the frame part 2. In other words, in such a solution, the second connection means 54' becomes part of the structure of the dental treatment unit only when the support structure with the vertical supports 41 is attached to the dental treatment unit.

[0047] Furthermore, the attachment structure for attaching the support structure 4 to the frame portion 2 can be realized in a manner other than the structure having two flanges shown in Figures 5 and 6. For example, the attachment device can be realized so that an engagement structure configured to match the structure of the support structure 4 is already pre-assembled to be connected to the frame portion 2. In this case, the engagement of the support structure 4 as part of the dental treatment unit can be performed automatically when the support structure 4 is assembled.

[0048] The cover structure of the floor-mounted frame part of the dental treatment unit shown in Figure 5 is sectioned to show a passageway 56. The passageway 56 continues inside the support pillars 50 and further through the support plate 53 as shown in Figure 6. The passageway 56 is arranged in a structure for the intended cables and tubes that can provide the necessary physical and / or control signals (these are, for example, water, compressed air, and / or electricity) to the instruments and / or devices supported by the support structure 4 and used via the dental treatment unit.

[0049] In one preferred embodiment of the present invention, a light device 55, 55' is positioned in association with the structure below the cover structure 22 of the dental treatment unit and is positioned to illuminate the seam location 23, i.e., one or more sealing elements 24 positioned at the seam location 23.

[0050] In one preferred embodiment of the present invention, the sealing element 24 is made partially or entirely of a translucent material.

[0051] In a preferred embodiment of the present invention, the sealing element 24 has at least one photoconductor that guides light to its upper surface when the sealing element 24 is illuminated, for example, by a light device 55, 55' arranged in connection with a structure below the cover structure 22.

[0052] The light devices 55, 55' can be any device configured to be compatible with the sealing element 24, but according to one example, the light devices 55, 55' have RGB LED components that can be controlled in a known manner to produce light of different colors, at least two different colors, and / or light pulsed in different ways.

[0053] The arrangement for illuminating or illuminating the seam location 23 (i.e., one or more sealing elements 24) can also be implemented such that different portions of the seam location 23 emit light in different ways. For example, in one embodiment of the present invention, some areas of the seam location 23 do not emit any light generated under the cover structure 22 or by the sealing elements 24, while in other embodiments of the present invention, some areas of the seam location 23 emit light of different colors.

[0054] The illumination of the splice location 23, or more precisely the light emitted by it, can serve many different purposes. For example, different illuminations can indicate whether the dental treatment unit is powered on or off, or can serve as a reminder that the suction tract of the dental treatment unit needs cleaning. Furthermore, it can indicate, for example, the need to clean the instrument tract of the dental treatment unit, that such a cleaning process is being performed, or that such a cleaning process has been completed. It can also indicate possible malfunctions of the dental treatment unit.

[0055] In a preferred embodiment of the present invention, the lighting at the seam location is controlled by the control system of the dental treatment unit (FIG. 7). Such control can be configured to occur directly from the control system, or alternatively, the lighting can be controlled via a user interface of the dental treatment unit, e.g., a graphical user interface. Control can be based in part on the identity of the person using the dental treatment unit, the identity of which is transmitted to the control system.

[0056] The control system of the dental treatment unit may be configured to output control signals for controlling at least one light-emitting component 555 or light device 55, 55' disposed in the dental treatment unit to generate light in at least two different ways, for example, to generate at least two different colors, pulsed and non-pulsed light, and / or light pulsed in at least two different ways.

[0057] Furthermore, the control system may be configured to associate at least one operating mode of the dental treatment unit with a particular color and / or a particular pulse of light, in which case the control system may comprise means for recognizing at least one such operating mode of the dental treatment unit and controlling at least one light-emitting component or light device to emit light of that particular color and / or pulsed in that particular manner.

[0058] The control system may also comprise means for receiving a user identification signal and based thereon identifying a person logged in as a user of the dental treatment unit, and the control system may be configured to have a user profile activated by said identification signal, the user profile providing options to select the colour and / or pulse of the light generated by at least one of said light emitting components (555) or light devices (55, 55'), so that the emitted light can be controlled from the control system in accordance with the user profile.

[0059] Another way of using lighting is, for example, personalizing the dental treatment unit, for example according to the color of a patient chair used in connection with the dental treatment unit or other elements used in the dental treatment unit.

[0060] Particularly in environments such as training facilities where the same room or facility can have at least two or even dozens of dental treatment units, some solutions according to preferred embodiments of the present invention allow for an overview of the functional status of dental treatment units in a particular facility at a glance. One preferred embodiment of the present invention actually has at least two dental treatment units according to the present invention in one room or facility (with the light emitting seam locations 23 extending beyond the substantially horizontal surface of the cover structure 22 all the way to the opposing vertical surface of the cover structure 22).

[0061] It is also possible to arrange dedicated lighting for each user or user group working in the same dental treatment facility. Figure 8 shows a state in which the seam positions of the cover structures of dental treatment units arranged in a treatment room have three different lights that can indicate, for example, that a first portion of the dental treatment units is not in use, a second portion is in use by users of user group 1, and a third portion is in use by users of user group 2.

[0062] In a preferred embodiment of the present invention, an apparatus is implemented in a dental treatment room or dental treatment facility, in which at least two dental treatment units having the above-mentioned cover structure are arranged so as to be simultaneously visible from at least one line of sight, and in each dental treatment unit, a sealing element arranged at a seam of the cover structure i) has at least one light-emitting element or ii) is made of or includes a translucent material, and a light device is provided below the cover structure, connected to the structure of the frame part, for illuminating the sealing element. In this case, the cover structure preferably has, at the seam, a substantially horizontally extending portion where at least one periphery of the cover structure changes into a substantially vertical portion, and the sealing element includes at least one light-emitting element or translucent material in both the horizontal and vertical portions of the cover structure.

[0063] Furthermore, even for an individual dental treatment unit, the color of the light can be configured to be set by the dental treatment unit's control system to correspond to the background color of the dental treatment unit's user interface, for example, as determined in the user's user profile.

[0064] According to one preferred embodiment of the present invention, the control system of the dental treatment unit comprises means for identifying a person logged in as a user of the dental treatment unit, and the control system is configured to have a user profile populated with options for selecting light and / or pulses and options for causing the control system to control at least one light-emitting component or light device to emit that particular light and / or light pulsed in that particular manner.

[0065] On the other hand, in connection with treatment operations, for example, a flashing light can be used to indicate situations where there is reason for staff to come to the dental treatment unit, or when the time reserved for the treatment of a patient or the time determined for a particular procedure is about to end.

[0066] According to one example, the control system of the dental treatment unit is configured to control the light device and / or at least one light-emitting component arranged on the sealing element to generate light of different colors or light that flashes in different ways, for example, based on the operating mode of the dental treatment unit or the status of an instrument or device used in the dental treatment unit.

[0067] Thus, the above and other functions of the light device can be implemented by configuring a control system of the dental treatment unit to output control signals, and by configuring at least one light-emitting component disposed on the light device and / or the sealing element to receive control signals from the control system of the dental treatment unit.

[0068] According to a preferred embodiment of the present invention, illumination of the seam location of a dental treatment unit provides the possibility to present information that corresponds in part to information that can be presented by a possible graphical user interface of the dental treatment unit, but in a way that can be easily noticed from locations other than the immediate vicinity of such a user interface, which can be particularly beneficial in embodiments of the present invention that relate to dental treatment facilities.
