Description

  The present invention relates to a dental care unit. In particular, the present invention relates to a device holder unit of a dental treatment unit that can store devices necessary for dental treatment during treatment. More particularly, the present invention relates to a device holder unit used by a dental assistant, and this unit usually comprises a so-called suction holder unit, but is also applicable to a device holder unit used by a dentist. The device holder unit typically includes a plurality of device-places arranged in parallel with the device holder.

  Two basic types of devices, usually instruments (eg, micromotors / turbines (drills), scalers, curing units, syringes, etc.) and suction devices that remove saliva and treatment by-products from the mouth are usually dental Connected to the treatment unit. The appliance and suction device are connected to the central unit of the dental treatment unit by a hose. The hose of the suction device is usually a semi-rigid tube and can be used for suction purposes by the negative pressure generated at the other end. The hose of the instrument can include water connections, air connections, and wires, in particular, according to the instrument type.

  A device holder unit or console is typically a device used by a dental assistant or dentist, in which devices can be placed and easily removed and used for work. Most typically, the device holder is installed side by side with the device holder unit.

  There are two basic types of device holders: open and closed. An open holder refers to a holder from which the device and its hose can be freely removed. A closed holder refers to a holder from which the device can be removed so that the hose remains threaded through the holder. Furthermore, the holders for instruments and suction devices have their own characteristics, in particular with regard to the holding area geometry and the different hose thicknesses required for different device types.

  To facilitate the dental care operation, the dental care unit generally identifies the removal of the device and performs some preparatory action when the device is removed from its holder, e.g. downstream of the suction hose. Includes a function to start the suction pump that is positioned. This function can be called activation. Therefore, in order to enable the relevant functions, the device console must include a detector that detects whether the device is in its holder. As used herein, activation of a device of a dental care unit refers to the action of a user taking one device from the console and identifying it as a device selection by the dental care unit. Identification is a necessary step if there are two or more such device options controlled by a single controller, or if activation of the device is related to some automatically initiated action.

Activation identification can be implemented in many different ways. The most commonly used are the following identification techniques:
Mechanical identification (eg microswitch),
Mechanical optical switch or optical (IR) switch (optical port),
Inductive or capacitive identification.

  Microswitch identification is based on buttons that are located in the holder and pressed by the instrument or suction head when they are placed in the holder. Microswitches are only available with open holders where the hose is removed during use. With a through-rolling holder, false identification can occur when the hose hits the microswitch.

  Inductive / capacitive discrimination is based on recognition of the electrical properties of the device. This works for both open and closed holders, but for example non-conductive materials cannot be detected by this method, so the device to be identified and / or its hose needs to be designed specifically for this purpose. (E.g. suction head / scaler handpiece).

  As the device hose travels through the closed holder, there is no substantial change around the holder that can be reliably detected, for example by an optical port, so the prior art optical method is an open holder. Can only be used.

  According to the prior art, the most suitable arrangement for each device and its own device holder among the identification techniques described above depends on the characteristics of the device and the device holder and also takes into account the cost effectiveness of the structure. Always selected. This functionality and characteristics described above for device holders and devices, as well as other functions and characteristics, impose restrictions on the possible locations of the device in the console.

  An object of the present invention is to provide an improved device console of a dental treatment unit that facilitates the work of a dental care worker and improves the versatility of the console, and a dental treatment unit including the improved device console. is there.

  The device console (device holder unit) according to the present invention comprises at least two device mounting parts arranged so that at least two devices used in dental treatment or two different device types can be fitted into the device console. Prepare. Each device placement unit further includes a device holder that keeps the device in a predetermined position in the device console. Furthermore, the order of the devices or device types in the device console can be changed, and the device holder unit comprises means for identifying the device or its type installed in the device mounting section when the device is installed in the holder. . The identification of the device / device type is performed using an optical sensor capable of color separation.

  According to the present invention, the device console includes, for example, a housing and a plurality of device holders connected to the housing, and the means for identifying the device and / or device type installed in the device mounting portion is the device mounting. In order to observe the part, it is positioned on the housing. Thus, when the device location is changed, the means can send a new device order of the console from the device console to the control unit of the dental treatment unit. Also, when the device is removed from the holder, the means can send an activation signal to the control unit.

  The dental treatment unit according to the invention comprises at least one device console and a central unit, to which is connected a device hose for using the devices necessary for dental treatment to be installed in the device holder of the device console. . The device hoses and their respective device holders are usually designed for at least two different device types such as suction devices and instruments to be connected to the dental treatment unit. The device console includes means for identifying a device or a type of the device installed on the device mounting unit when the device is installed on the holder.

  Most preferably, the identification of the device or its type is based on a specific color identifier (or lack of color identifier) located on the device or particularly preferably the device hose. Thus, in a two device type system, there should be an identifier on at least the other device type device or hose. Preferably, the identifier is a color code located at the end of the device hose close to the device. That is, it is placed in a region that remains in or near the device holder when the device is in its predetermined position. Correspondingly, a sensor capable of color separation, such as a light source / detector configuration using two or more different wavelength ranges, is used as the identification means. The sensor is positioned in the device holder unit such that light emitted by the one or more light sources is reflected or scattered from the device installed in the device holder or from its hose to the detector.

  For device type identification, for example if the suction hose has a color identifier, there is no need to use a separate identifier on the instrument hose. On the other hand, if there are multiple device types to be identified, these can have their own color code that the identification means senses. Thus, in further applications, the present invention allows identification of the order of individual devices as well as the device type order.

  Most preferably, the identifier is local so that it is detected only when the device is still in its holder. Such an identification structure is closed, for example in contrast to an optical port or a mechanical switch, because a change in activation mode is detected when the hose is pulled out (when the identifier leaves the vicinity of the sensor). It is also applicable to be used in the case of a mold device holder.

  According to a preferred embodiment, the device holder is separable from the housing, and means for removably receiving the device holder are arranged in the housing.

  The present invention provides significant advantages. That is, identifying the order of installation of individual devices or device types in the console allows the dental treatment unit to be quickly reprogrammed whenever the device order in the console changes. Thus, the dominant hand of the console, as well as the dominant hand of the entire dental care unit, can be easily changed, for example, by the habitual procedure or left / right handedness of a dentist or dental assistant. By identifying the instrument type, an accurate activation signal can be sent to the control unit of the device even if the device order at the console has changed.

  To date, device consoles have had a specific fixed location for each device and specifically for each device type, with a unique activation identifier designed for that device. Therefore, it was not necessary to identify the device type. In the arrangement according to the invention, the identification of the device type prevents a change in the device order at the console from leading to an incorrect activation identification signal and thus an incorrect activation of the device.

  The means according to the invention for identifying the type of device installed in the device holder is applicable for simultaneously identifying whether the device is in its predetermined position in the holder or removed from it. Please keep in mind. Thus, a separate activation identifier is not necessary.

  The term “device type” mainly refers to the category commonly used in dental care to distinguish between suction devices and instruments. After reading the detailed description of the present invention, those skilled in the art will understand that the present invention can be more widely applied to other categories of device types. Furthermore, the present invention can also be used to identify individual devices in a device console (eg, to distinguish two instruments of the same type, such as two turbines) from each other.

  In the aspiration device console, the aspiration device is almost always installed in a closed device holder because it can make the very rigid hose of the aspiration device easier to control during treatment. Nonetheless, the above-mentioned drawbacks associated with identification techniques have limited changes in the placement order of devices on the console. By using various embodiments of the present invention, this disadvantage, particularly with respect to the prior art, can be eliminated. More generally, an instrument console used by a dentist will also benefit. Thus, dentist's normal instruments such as drills, syringes, dental imaging cameras, UV curers, or corresponding special instruments can also be handled completely as unique device types.

  An optical sensor capable of color separation mainly refers to a sensor capable of spectrally separating different colored surfaces, ie at least two different colored surfaces from each other. Thus, such sensors utilize information regarding the spectral intensity distribution of the light in addition to the intensity of the reflected or scattered light.

  Next, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 3 shows a stepwise perspective view of the configuration of the sensor arrangement according to FIG. 2.

FIG. 3 shows a stepwise perspective view of the configuration of the sensor arrangement according to FIG. 2. FIG. 3 shows a stepwise perspective view of the configuration of the sensor arrangement according to FIG. 2. The side view of the light beam pattern of a sensor structure is shown as an example. Figure 2 shows a side cross section of one possible sensor arrangement. The problem behind the present invention is shown. The perspective view of the structure of a device console provided with the adjacent device mounting part and its associated sensor module is shown. The perspective view of the structure of a device console provided with the adjacent device mounting part and its associated sensor module is shown.

  FIG. 1 shows one device console 10 to which five device holders 12, 13, 14, 15, and 16 are connected as an example. Holders 12 and 13 are conventional open tool holders and are shown to bend at different angles. Holders 14 and 15 are conventional open suction device holders, which are also shown in different positions. Holder 16 is a closed suction device holder, which is an open holder in that the hose that passes through the holder "advances" over the rollers located therein rather than coming out of the holder during use of the device. Is different.

FIG. 6 shows, as an example, one possible console configuration with devices connected. The device holder is indicated by letters A to E. Holders C and D are open, and the other holders are closed. Suction devices (dark ones) are indicated by the letter I _n, the instrument is indicated by the letter i _n. The arrows at the bottom of the figure indicate the possibility of changing the order of the device holders.

  The holder sequence configurable by the user requires that each device rest has an identification means that can identify the suction hose / suction device and the instrument hose / instrument from each other. Simple optical or mechanical identification, such as measuring switches, optical ports, or simply reflected intensity, does not give the desired end result. The use of optical ports and mechanical switches is excluded because the suction hose / suction device and instrument hose / instrument geometry are very similar. On the other hand, the gloss levels of the devices are so variable that the devices are not distinguished from each other by reflection. In particular, these techniques do not provide simultaneous identification of device type and activation mode with a closed holder, and reflection will occur regardless of whether the entire hose is in the holder or pulled out.

  In the following, one general structure relating to device type identification, i.e. a structure considering the total degree of freedom of the current console structure will be described in more detail.

  It has been found that the use of color identifiers and color separable identification reliably and cost effectively solves both the type and activation identification problems. For example, if the ring connected to the suction hose is dyed in a different color than the rest of the hose, it can then be identified whether the suction hose is in its holder or pulled out. Using the same identification means, it is possible to see if the device in the open holder is in the holder or removed from the holder. If it is desired to provide a structure in which devices of both device types are in a closed holder, the hoses can be marked differently from each other (eg device type 1: gray hose, blue cord; device Type 2: Red hose, gray (free) cord). It is not necessary to change the detector.

  Applicable detectors can be manufactured in many different ways. The basic principle is to send light towards the device or device hose by the first element and detect the reflected light by the second element. These elements are arranged relative to one another so that differently colored surfaces give different responses at the detector. These elements can be narrowband or broadband, or for example dual frequency light (two sources with different bands). From the detector signal, a specific wavelength or band or a plurality of wavelengths or bands can be selected, from which the color of the reflecting surface can be estimated. Most preferably, the identification is performed by comparing the intensities of the two wavelength bands with each other.

  Referring now to FIG. 2 (and FIGS. 3a-3f), one embodiment senses two light sources 206, 208 (306, 308) in different wavelength ranges, preferably LED light, and these wavelength ranges. A detector 210 (310), preferably a photodiode, is utilized. The light sources 206, 208 (306, 308) and the detector 210 (310) are positioned so that the light emitted by the light source is reflected from the device installed in the device holder 202 (302) or its hose to the detector. It is done. Light from the light source can be directed in a desired direction using a prism 218 (318) or some other light guide. As shown in the figure, the prism is a double prism that is common to both light sources, and achieves a very small sensor structure. Components and other electronic components that may be needed can be placed on the circuit board 228 (328). The resulting optical unit is placed in a module 204 (304) that will be placed in the device console. The module has one or more openings 222 for light. The module may be placed in a console support 224 (324). Device holder 202 (302) is placed in close proximity to the module so that it remains optically connected to a device or hose that can be placed in the holder. The legs of the light sources 206, 208 (206, 308) are attached to the circuit board 208 (308) (not shown). The embodiments and assemblies that provide the desired effects can vary greatly from those shown.

  In addition to being preferred and very suitable for color separation, the above-described embodiments have been found to allow the production of detectors that are very narrow in the lateral direction. The advantage of multi-prisms is that a more consistent light is provided to the target by appropriately scattering the light beam. Therefore, the geometrical tolerance of the color identifier and the detector arrangement is increased.

  Correspondingly, different color light sources and broadband detectors, broadband light sources and multi-band detectors can be used.

  The embodiment shown in FIG. 5 comprises a transmitter 58 implemented with white LEDs, whose signal is evaluated using two pairs of photodiodes 59 located very close and filtered for blue and red light. The This technique has been found to be preferred and functional.

  Preferably, wavelength ranges with distinct differences from one another, for example blue light and red light, are used, and the corresponding blue and red identifiers are used. It will be appreciated by those skilled in the art that the techniques described can be used to implement applicable sensors to reliably resolve even more colors.

  The color identifier is a plastic or metal sleeve or label placed on or around the device hose or connector, and preferably is capable of 360 degree identification. The sleeve can be dyed in a manner known per se, for example by painting or anodizing. In order to ensure reliable operation of the identifiers, the specular reflection of those identifiable wavelengths is preferably at least 1%, most preferably at least 10%. On the other hand, the measurement can be based on the scattering of light from the surface and even on the secondary light, ie fluorescence or phosphorescence.

  In a preferred embodiment of the present invention, the “depth vision” of the optical sensor mechanism is preferably the sensor 40, 50, for example in the case of the arrangement shown in FIGS. It is restricted so that it does not pick up false signals from clothes, etc. of medical personnel entering nearby. Preferably, the depth of vision of the photosensor is limited to the area of the holder 42. The field depth limitation according to FIGS. 4 and 5 is based on the angular position of the light source beams 44, 54 and the beam 46, 56 viewed by the detector relative to each other. The angle is preferably 2 ° to 45 °, usually 5 ° to 25 °. Since the divergence angle of the beam is limited, their intersecting areas are limited. Therefore, the color surface to be identified must fall within this intersection area. The length D of the identification area can be, for example, 1 cm to 3 cm, i.e. comparable to the diameter of the hose and holder.

  If the light source or detector beam divergence angle is inherently large, as is generally the case with semiconductors, the beam divergence angle is preferably one or more collimators placed between the component and the target. Limited by. The collimator is preferably located in the sensor housing or connecting element or in the console shell. In FIG. 5, the collimator is indicated by reference numerals 51 and 52. At the center of the beam, the intensity can also be highest and unwanted orientational reflections can be minimized.

  The dental treatment unit can be configured to automatically learn or can be taught to identify the device type in situations where all of the suction and instrument hoses are in their place. When taught, the dental treatment unit may identify a target that strongly reflects a particular color, eg, blue, as a suction hose, and a target that reflects, for example, grayscale (eg, blue and red) as an instrument. For teaching purposes, the device preferably comprises a button that is learned while pressed. Alternatively, learning can be performed, for example, in connection with the start-up of the device or in connection with some other specified action (for example, changing the handedness of the device and / or moving the dental chair to the treatment position). . If the mutual order of devices of a particular device type does not change (for example, suction hoses are in the same order as each other and instrument hoses are in the same order as each other), such simple teaching based on color sensors is completely sufficient. is there. In the case of a completely freely configurable console (device hose can be crossed), further teaching through the user interface is still required when using single color identification. This problem can naturally be solved by using a multicolor sensor mechanism.

  If the target to be identified is in a position substantially deviating from normal to the sensor, the behavior of the identifier can change. If the device holder is pivotable, the sensor can be pivotably disposed with the device holder, such as the one shown in FIGS. Thus, the identification set can be assembled on individual cards that are bused together. The detector optics can remain under the cover or lens, allowing the device to be easily cleaned.

  FIGS. 7a and 7b show the arrangement of the identification module 73 on the device console as an example. Each module is arranged as a unit that rotates separately in the vertical direction so that the sensor mechanism rotates with the device holder 71 connected to it. Reference numeral 75 denotes a spring arranged to lock the connection element of the device holder 71 to the module 73.

  With particular reference to the constructs shown in FIGS. 2-3, sensor electronic control is preferably performed to include compensation for ambient light (eg, sunlight and room lighting) to avoid misidentification. Sunlight and bulb light can be compensated by using a short identification period and by compensating for “DC light” or substantially constant light components from the detector signal. Fluorescent light is also removed from the result by taking two measurements in succession with the detector (considering the vibration frequency of the light, typically 50/60 Hz), obtaining the comparison result from one of them and the measurement result from the other. can do. During the measurement, a signal is transmitted by the desired light source. When they are subtracted from each other, the remainder is substantially contributed by the light source. On the same principle, the measurement is repeated, preferably in a continuous cycle, for all the wavelength ranges used.

  If it is desired that the light generated by the light sensor is not perceptible to the eye or at least not disturbing, the pulse of the light source can be kept very short or at least its flicker frequency is undetectable by the eye Can be adjusted as follows.

  To increase the dynamic range of the detector, the measurement electronics preferably include adjustable attenuation, which can be used to convert the analog voltage to the measurement voltage generated by the light received by the photodiode or some other sensor element. This voltage reaches the desired region before digital conversion and further processing.

  Preferably, the sensor continuously identifies so that activation of the device can be identified immediately after implementation (or return) and the desired control of the physical quantity associated with the device (usually pressure control or electrical control) can be initiated (or terminated). Use a periodic or very rapid periodic identification cycle.

  The central unit preferably includes a programmable unit that can be programmed with device type or device information for each color identifier. The central unit is configured to use this information to enable (non) activation of the physical quantity for this device platform, especially when it detects the removal (return) of a device from any device platform. .

  The console may include a light indicator to indicate the mode of each holder (presence or absence of device in place).

The present invention
At least two, usually two to seven platforms for the instrument / suction holder,
Normal dental instruments and / or the availability of at least one closed suction holder or such holder,
Is particularly suitable for device consoles and dental treatment units.

  There is no prior art identification method that works with devices that meet the above criteria themselves. The biggest obstacle is that the suction holder is in a closed form, which is important with respect to the smoothness of the treatment (the suction device automatically returns to the holder). In particular, according to the invention, a new suction with at least one closed suction device holder for the suction device and at least one other holder for another device so that the order of the devices in the console can be changed. A device console can be realized.

  A common problem with mechanical sensors is poor hygiene. Electrical sensors also generate radio frequency interference in the environment (EMC), which makes them less suitable for new products. The electrical sensor also picks up the disturbance signal from the environment, so the treatment is disturbed.

  In the case of separable instrument holders, their type can also be identified by some construct if desired.

  The described identification techniques can be used for special devices and unknown dental devices as well as for conventional suction devices or instruments. An example may be a suction device provided with some dynamic device such as a motor, turbine, intraoral camera, light curing device, or tartar removal scaler.

  Note that with respect to dental care devices, several systems are known that identify which device is connected to which device port of the dental care unit. EP-A-0736288 suggests using an impedance measured through the code of the device to identify the device. A system for identifying dental imaging cameras is also described in Finnish patent 109521.
