Definitions

  • the present invention relates to dental treatment units, and in particular, to a base for said units allowing an easy replacement of a dental treatment unit already installed in a dental practice with a new dental treatment unit.
  • Dental treatment units have been industrially produced for several decades, and comprise a plurality of instruments allowing a dentist to administer dental therapies to a patient. Typically, they comprise a patient chair, a hydrogroup, a scialytic lamp, a dentist's board, an assistant's board generally provided with suction cannulas.
  • the two configurations a and b have been known for a long time in the art, too.
  • US3650033A1 of Siemens AG shows a patient chair of the chair mounted type, wherein the hydrogroup is integrally connected to the patient chair through a connecting arm, while the patient chair is fixed to the floor.
  • Figure 2 of US3650033A1 shows a patient chair 1 and a hydrogroup 10 connected through a connecting arm 35.
  • a parallelogram arm 8 allows the rising and lowering of said patient chair 1, which thanks to its integral connections to the hydrogroup 10 through said arm 35, drags said hydrogroup 10 rising and lowering it with respect to the floor.
  • EP0100491A2 of Siemens, published in 1984
  • EP0895769A2 again of Kaltenbach & Voigt, published in 1999
  • EP0100491A2 provides an unusual solution, wherein the doctor's device 2 and the assistant's device 3 move backwards and forwards with respect to the patient chair 1, along two linear paths parallel to the longitudinal axis of the patient chair.
  • the two devices 2 and 3 are placed on the opposed sides of said patient chair. In other words, a movement on the horizontal plane, i.e. the plane of the floor, is provided between the patient chair and the two devices.
  • DE1822226U of EMDA published in 1960 , describes a solution of the type b, i.e. a suspended chair dental treatment unit, with a hydrogroup fixed to the floor provided with a vertical movement for the patient chair with respect to the floor, well visible in Figure 2 of DE 1822226U
  • Other known art documents are EP2086489A1 of Kaltenbach & Voigt, published in 2009 , and EP2526916A1 of Planmeca, published in 2012 .
  • the unit is shiftable orbitally and laterally with respect to the chair so that the instrument center can be located in the correct position relative to the position of the headrest of the chair throughout the range of adjustment of the chair back.
  • the invention described in this patent allows to move the hydrogroup (called dental unit 12) with respect to the patient chair 11, in order to obtain alternatively a first configuration wherein the hydrogroup is placed on the right of the patient seated in the chair or a second configuration wherein the hydrogroup is placed on the left of the patient seated in the chair.
  • a movement on the horizontal plane of dental unit 12 with respect to the patient chair 11 is provided.
  • vacuum connection 52 electric connection 53, compressed air connection 54, water connection 55, and a drain or waste connection 56, i.e. the well 51, is located under the base assembly 10, inside the outline of the patient chair 11.
  • These connections must allow the movement of the dental unit 12 around the patient chair 11.
  • the hydrogroup is a structural portion of the dental treatment unit, which generally allows to support the dental treatment unit portions different from patient chair, i.e. the assistant's board, the scialytic lamp, optionally the dentist's board, which in its turn supports a plurality of dental handpieces (dental syringe, micro-motor, turbine, polymerizing lamp, dental camera, etc.). Often the hydrogroup also supports a bowl and a water-to-cup spout.
  • the hydrogroup is substantially a hollow structure housing reservoirs, electronic boards, piping and wiring. These components are hidden from view, so that the dental treatment unit shows a pleasing and reassuring look for patients.
  • Patient chair must be connected to electric energy for its movements; dental handpieces generally need be fed with electric energy, compressed air and water; suction cannulas must be connected to a suction device. Moreover, the liquids coming from the dental treatment unit must be conveyed to sewer drain. Generally, under the floor there are provided systems providing the necessary feeds, and the drain of liquids. These systems generally come out from the floor in contiguous points, forming a connections box.
  • connections box relates to the set of all the supplies (i.e. suction, compressed air, water, electric energy and drain) that are needed for the functioning of dental units, i.e. the piping and wiring providing said supplies in their point of emersion from the floor, which piping and wiring are typically placed inside a small area, called connections box.
  • supplies i.e. suction, compressed air, water, electric energy and drain
  • connections boxes are provided so as to arrive directly under the dental treatment unit; e.g. see US3524676A of Cocherell et al. In this way, they remain hidden from view, once the dental treatment unit is installed in a dental practice.
  • the piping and wiring conveying suction, compressed air, water, electric energy and drain piping come out from said connections box, which generally lies on the floor; then they continue in order to establish a connection to said dental treatment unit in a site called feeds entry point.
  • Each manufacturer of dental treatment units provides its own characteristic arrangement of the internal organs of the hydrogroup, in particular with respect to the connections box. This allows to easily replace an already installed dental treatment unit with a new dental treatment unit provided with its connections box arranged in the same position.
  • Aim of the present invention is providing a dental treatment unit allowing to easily replace an already installed dental treatment unit with a new one, even when the already installed dental treatment unit is provided with a different arrangement of said connections box.
  • the present invention is applicable to dental units of the suspended chair dental treatment unit type.
  • the present invention reaches this aim by providing a hydrogroup base allowing the connection of the feeds entry point in the hydrogroup with all the main positions of the connections boxes known in the art. Moreover, each of the connections boxes is covered by a respective aesthetic housing hiding from the view feed piping and wiring (for suction, compressed air, water, electric energy and drain) from their point of exit from the floor and for a portion of such piping and wiring. Said aesthetic housings are provided adjacent and in continuity with the aesthetic housing covering the base of patient chair, so as to form a visual-functional unit, preventing the running of free piping and wiring on the floor, which poses a serious danger for the safety of dental staff and patients.
  • Said base is substantially a plate in continuity with the base of the hydrogroup lying on the floor.
  • Said base is provided with a bottom shape allowing the passage of said piping and wiring between the floor and the base itself, while in some portions of the base said piping and wiring run on the base itself.
  • the base which is the same for all connections boxes (C1, C2, C3, C4) is provided with a U-shape, lying on the floor, comprising a base of said U which is adjacent and preferably integral with the base of the hydrogroup, and two arms of said U, needed for the stability of the dental treatment unit.
  • Said U arms are shaped in order to allow the passage of piping and wiring for connecting to C1, C2, C3, C4 connections boxes, while maintaining the structural stability that the base confers to the dental treatment unit.
  • a first arm of said U is called front arm, while a second arm of said U is called rear arm, with respect to the position of the patient chair and of the patient lying on said chair.
  • Said U front arm and rear arm are provided with different shapes.
  • the base of said U is provided with its internal edge comprised between the two U arms that is raised with respect to the floor, in order to allow the passage of piping and wiring.
  • the rear U arm is provided with a hollow upside-down U shape in order to allow the passage of piping and wiring between said arm and the floor to which said dental treatment unit is fixed.
  • Said upside-down U forms a sort of longitudinal tunnel parallel to the axis of said rear arm.
  • the front U arm is provided with a raised shape in the portion proximal to the U base, while in its distal portion said arm adheres to the floor, in order to allow the passage of piping and wiring on said distal portion.
  • the proximal portion of the U arm is coplanar to the U base, while the distal portion of the U arm is lower than the U base, and therefore nearer to the floor.
  • a first advantage is easing and accelerating the replacement of a dental treatment unit already installed in a dental practice with a new one, by exploiting the already existing hydraulic/electric/pneumatic connections.
  • a second advantage is the possibility of replacement without the need of masonry/hydraulic/electric/pneumatic works.
  • the third advantage is the possibility of maintaining the same outline on the floor of the patient chair already installed in the dental practice, without the need to move the new dental treatment unit in order to connect it to the floor feeds already present. Therefore, the room for manoeuvre for dental staff remains the same.
  • a fourth advantage is the improvement in safety for dental staff and patients, in that the aesthetic housings form a visual-functional continuity with the floor outline of the dental treatment unit, preventing the possibility of tripping in flying connections.
  • a fifth advantage is that the aesthetic housings according to the invention are modular. According to the connections box already present in the dental practice, a housing can be chosen to obtain a dental treatment unit pleasing to the eye, but especially safe for dental staff and patients.
  • FIGS 1A, 1B show a chair mounted dental treatment unit 10 that is part of the present production of the applicant.
  • Said chair mounted dental treatment unit comprises: a patient chair 1, a hydrogroup 2, a bowl 3, a dentist's board 4, an assistant's board 5, and a headrest 9.
  • the vertical movement of the patient chair 1 is performed through a pantograph mechanism arranged in the base of patient chair 1, provided with a pantograph arm 6.
  • the patient chair 1 and the hydrogroup 2 are integrally connected through a connecting arm 8 (visible in Figure 1B only), and therefore patient chair and hydrogroup rise and lower at the same time.
  • FIGS 2A, 2B show a floor mounted dental treatment unit 20 that is part of the present production of the applicant.
  • Said floor mounted dental treatment unit comprises: a patient chair 1, a hydrogroup 2, a bowl 3, a dentist's board 4, an assistant's board 5 and a headrest 9.
  • the vertical movement of the patient chair 1 is performed through a pantograph mechanism arranged in the base of patient chair 1, provided with a pantograph arm 6.
  • the hydrogroup 2 remains stationary, while the patient chair 1 rises and lowers with respect to the floor and the hydrogroup.
  • the patient chair 1 and the hydrogroup 2 are substantially independent.
  • FIGS 3A, 3B show a suspended chair dental treatment unit 30 that is part of the present production of the applicant.
  • Said suspended chair dental treatment unit comprises: a patient chair 1, a hydrogroup 2, a bowl 3, a dentist's board 4, an assistant's board 5 and a headrest 9.
  • the vertical movement of the patient chair 1 is performed through a raising/lowering mechanism arranged inside the hydrogroup 2, comprising a mechanism for raising and lowering the patient chair through an arm 7 (visible in Figure 3B only).
  • the hydrogroup 2 remains stationary, while the patient chair 1 rises and lowers with respect to the hydrogroup 2 and the floor.
  • Figure 4 shows an axonometric simplified view of a dental treatment unit 100 of the suspended chair type according to the present invention, comprising a patient chair 41 and a hydrogroup 42.
  • Figure 4 shows the main alternative positions of the connections boxes C1, C2, C3, C4. Obviously, in reality, just one of the shown connections boxes is present in the floor of the dental practice, and to this connections box the already installed dental treatment unit is connected. In particular, there are shown the respective positions of:
  • the present invention allows reaching the feeds entry point 50 (visible in Figures 5 ) from any of the connections boxes C2 or C3 or C4 thanks to a base 51 according to the present invention.
  • Over said connections boxes there are provided specific aesthetic housings, allowing to cover the path of piping/wiring from the different positions C2 or C3 or C4 of the connections box to the feeds entry point 50, placed under the hydrogroup 42.
  • Said aesthetic housings are placed in continuity with the housing covering the base, and therefore there are provided no free-running piping/wiring, and anyway the housings are in a visual-functional continuity with the dental treatment unit.
  • FIGS 5A, 5B , 5C, 5D show the hydrogroup 42 without its aesthetic housing and allow to appreciate the path of the piping/wiring coming from C1, C4, C2 and C3 connections boxes, respectively.
  • Said hydrogroup 42 comprises a known metallic frame 52 having a parallelepiped shape.
  • Said metallic frame 52 is a structure supporting the functional internal components (not shown reservoirs, piping, electric boards, wiring), which is in its turn integral with said base 51.
  • the metallic frame of the hydrogroup can be likened to a boxed body, in fact its faces are actually its two top and lower bases. Its four lateral faces are open; there are provided just the edges of the boxed body.
  • the metallic frame of the hydrogroup is closed and hidden from view by an aesthetic housing, generally made of a suitable plastic material.
  • Said base 51 which remains the same for all C1, C2, C3, C4 connections boxes, is provided with a U-shape laying on the floor, comprising a U base 53 that is adjacent and integral with the base 43 of the hydrogroup, and two U arms 54, 55, needed for the stability of the dental treatment unit 100.
  • Said arms are shaped in order to allow the passage of piping/wiring to the C2, C3, C4 connections boxes, maintaining the structural stability of base 51.
  • the U base 53 is provided with an internal edge, comprised between the two U arms 55, 54, raised with respect to the floor, in order to allow the passage of piping/wiring.
  • the U base 53 is provided with a bore 56 for a (not shown) wall plug allowing to fix the dental treatment unit 100 to the dental practice floor.
  • Other two bores 57 are provided on the external side (the side opposed to the chair side) of the base 51.
  • the U first arm 55 is defined front arm with respect to the position of the patient chair 41 and of the patient lying on it, while the second U arm 54 is defined rear arm with respect to the position of the patient chair 41 and of the patient lying on it; in particular the rear arm is oriented toward the headrest 9.
  • Said U front arm 55 and U rear arm 54 are provided with different shapes.
  • the U rear arm 54 is provided with a hollow shape, channel-like and/or having an upside-down U transversal section, in order to allow the passage of piping/wiring between said arm and the floor to which the dental treatment unit is fixed.
  • Said channel-like with upside-down U section forms a sort of longitudinal tunnel parallel to the axis of the U rear arm 54.
  • said channel-like shape of said rear arm 54 ends up with one of its open head ends in said base 53.
  • the U front arm 55 is provided with a raised portion proximal to the U base 53, while in its distal position it adheres to the floor, in order to allow the passage on it of the piping/wiring.
  • the proximal portion of the arm 55 is at the same height of the U base 53 in its top side.
  • the lower edges of said front arm 55 oriented downwards are raised in a given measure with respect to the floor, so forming lateral passages from side to side of the front U arm 55 in correspondence of said proximal portion to the base 53.
  • Figure 5A shows the position of the connections box C1, which is adjacent to the rear short side of the metallic structure 52, and in use is covered by the aesthetic housing of the hydrogroup, forming a visual-functional unit. As it easily observed, this is the simplest configuration, as the connections box C1 is in correspondence to the feeds entry point 50.
