The invention relates to a medical or dental-medical instrument or a supply apparatus and/or a maintenance apparatus or a system for medical or dental-medical instruments in accordance with the preamble of claims 1, 6, 9, 10 or 13.
The configuration and functioning of an instrument of the kind concerned can, moreover, differ widely. In particular with an instrument as mentioned above, the tool of which is moved by means of a drive, there is needed at certain intervals a mechanical servicing of the at least one instrument in order to maintain its capability for functioning and to avoid wear and disruptions to functioning. There are instruments with which, independently of whether they have been soiled and/or contaminated in functional operation, there is a rule that the instrument be serviced at certain intervals, e.g. after certain numbers of operating hours. The above-indicated measures for the maintenance of the readiness for use of the at least one instrument are designated in the following by the term “maintenance”. Thus, for an instrument of the kind concerned, there is a working phase, in which it acts on the body at least for some periods of time, and a maintenance phase, in which the instruments acted upon for maintaining its readiness for use.
In DE 42 20 522 Al there is described a system for making recognisable various consumer loads, for example dental instruments, with respect to an energy supply unit belonging to a dental treatment station, with a coding means provided on a supply line for the identification of an instrument associated with the supply line and with an evaluation circuit belonging to the energy supply unit which is connected by means of electrical connecting lines with the coding means. The electrical connection lines extend through the supply line.
Further, the invention is based on the object, with a supply apparatus in accordance with the preamble of claim 6, of improving or broadening the carriage of data.
This object is achieved by means of the features of claim 6. With a supply apparatus in accordance with the invention according to claim 6, the data receiver or a reading device is also a data transmitter for the transfer of data to the memory element. Through this, data can be issued through the supply line and the data store of the supply apparatus can be relieved from demands at least for the time for which the instrument is decoupled from the supply apparatus, since data relating to the memory element can be given to the memory element. Beyond this, this configuration in accordance with the invention leads to a substantial simplification of the supply apparatus because in the case of the presence of a plurality of supply apparatuses, with which the instrument can selectively be coupled, no direct data line between the apparatuses is needed. The carriage of data can namely be assumed by the instrument with its data transferred in each case from the apparatus. When the instrument is coupled with a second apparatus, the second apparatus can call up the data from the instrument so that a direct data line between the apparatuses is not needed.
The invention is further based on the object of improving and/or simplifying the functioning and/or control of a maintenance apparatus in accordance with the preamble of claim 9.
This object is achieved by means of the features of claim 9.
The maintenance apparatus according to claim 9 has a reading device for reading out identification and/or operational parameter data stored in the instrument. Through this, the maintenance apparatus can be controlled in dependence upon identification and/or operational parameter data. Thereby there takes place an automatic adaptation of the functioning or control of the maintenance apparatus to the respectively read out identification and/or operational parameters. Further, this configuration also leads to a substantial simplification of the maintenance apparatus, because in a functionally connected system with at least one further apparatus there is needed no direct networking between the apparatuses, since the data carriage can be effected via the instrument and called up upon the coupling of the instrument with the apparatus concerned.
This object is achieved by means of the features of claim 10.
With the system according to claim 10, the maintenance apparatus is also connected with the computer, whereby it stands in data exchange also with this computer. Through this, the maintenance apparatus can be controlled from an available computer and can be simplified, since the maintenance apparatus does not need its own controller means. Beyond this, control data can be put to use which is already stored in the computer of the supply apparatus, since the supply apparatus is also set up for the supply of the instrument, and thus for the control of the maintenance apparatus there can be put to use the available identification and/or operational parameters.
This object is achieved by means of the features of claim 13. With a system according to claim 13, there are provided registration means, by means of which the development or the desired value and/or actual value of at least one operational parameter of at least one operational phase is or are registerable. Through this, there can be recorded and understood and represented, and if applicable documented, selectively data and/or functional sequences of the system concerning the actual operation of the instrument. Through this an investigation of the operational sequence is substantially simplified.
It is particularly advantageous to detect and to register the actual value of the at least one operational parameter or feature. This is inter alia advantageous for the monitoring and/or improvement of safety, because the actually attained actual value is determined and can be registered, rather than a value set by the manufacturer or a user-specific value, for example a tool speed of rotation in the case of a treatment device, or a sterilisation temperature in the case of a steriliser. Thus, there is taken into consideration the parameter value which is important for technical safety reasons with regard to a working procedure and/or maintenance procedure. This is, for example, clear in the case of a maintenance device in the form of a steriliser. If the steriliser does not attain the predetermined actual value of the sterilization temperature in the maintenance phase this can be detected or determined with the system in accordance with the invention and thus understood and if applicable also documented. This is particularly important in relation to the furnishing of proof or evidence, for example with regard to warranty claims and/or fulfilment.

For carrying out different types of work there may be associated with the working device 1 a plurality of instruments 2, as is per se known. FIG. 2 shows by way of example an instrument 2 in the form of a so-called angled piece. The instrument or instruments 1 may thus involve such different constructions and functions as are in each case appropriately formed with regard to the coupling 8, so that they can be selectively coupled onto the connection part 9 and are exchangeable. There may be involved an instrument having a drive shaft axially extending thereon, which is rotatable by means of a motor M, for example an electric motor, arranged in the connection part 9 and which stands in driving connection with the tool 6. The tool 6 may be also be driveable by means of a compressed air turbine arranged in the forward end region of the instrument 2, which turbine is supplied by means of a compressed air delivery line and discharge line extending from the supply apparatus 3 and longitudinally through the supply line 4, the connection part 9 and the instrument 2.
For the delivery of operating media or working media the instrument may have an air line, a water line or a spray line, which in a manner known per se emerge in the forward end region of the instrument 1 and are directed towards the work site. The instrument 2 may also have an illumination device having a longitudinally extending light conductor or a longitudinally extending electric line with lamp, which extend to a light exit arranged in the forward end region of the instrument 1. For the supply of the above-described devices there serve so-called media lines which extend from a supply unit 3a of the supply apparatus 3 through the supply line 4 to the associated consumer load in the connection part 9 or in the instrument 2. If a turn/plug-in coupling is provided, a media line can in particular pass through this co-axially in a sealed manner and/or a plurality of media lines can pass through the cylindrical dividing joint between the coupling pin 8 a and the coupling recess 8 b in a sealed manner in a Z-form, as is per se known. For making more clear these per se known relationships there are schematically illustrated in FIG. 1 by way of example three media lines 18, 19, 20 for water, compressed air and light, which pass through the coupling 8 co-axially or Z-like.
In the case of the exemplary embodiment according to FIGS. 8 and 9, in which the same or similar parts are provided with the same reference signs, the reading direction of the reading device 10 b is radially directed, here radially inwardly. In the case of the exemplary embodiment, there are arranged a plurality of photocell sensors 10 d next to one another, in the circumferential direction with regard to the coding 10 a, and radially outwardly. The coding 10 a is formed by means of a light-dark marking on an outer circumferential or segment surface, in particular by a bar code. As FIG. 9 shows, the coding 10 a and the reading device 10 b are arranged on parts of the coupling parts lying radially opposite one another. Here, the coding 10 a may be arranged on an outer surface of an inner shoulder 2 b on the instrument 2 which is engaged over by the reading device 10 b. The photocells, preferably present in a plurality, can on the one hand be arranged on a forwardly directed end face of the connection part 9 and on the other hand brought together in a sensor ring segment. A free space receiving the reading devices 10 b may be covered over by a projecting sleeve extension 9 a of the connection part 9. A parallel-serial converter or evaluation circuit is designated by 10 g.
The exemplary embodiment according to FIGS. 9 and 10 shows an identification device 10 having an in particular magnetic sensor 10 h, for example a Hall sensor or a field plate, in appropriate arrangement behind the radial dividing joint of the connection part 9. A magnet 10 i is arranged in the sleeve wall 2 a opposite to the sensor 10 h in a rearwardly opening recess 22. FIG. 11 shows schematically the arrangement and the electrical connection of the sensor 10 h in the case in which an illuminating device having a lamp 23 is present, which in the case of the exemplary embodiment is arranged in the connection part 9 offset in the circumferential direction with regard to the sensor 10 h, and feeds light into a light conductor 24 extending forwardly in the sleeve wall 2 a and arranged in the instrument 2 opposite to the lamp 23. The sensor 10 a is connected through electrical line sections 10 j to the current circuit 25 of the lamp 23. The coding 10 a can be constituted in this exemplary embodiment in that different instruments have magnets 10 i having different strengths of electromagnetic fields and/or the air gap spacings between the Hall sensor 10 h and the magnets 10 i is in each case different in the coupled condition. Through this, there are produced different electrical potentials in the sensor 10 h which are delivered through a signal line of the electronic control device 13, which extends from the sensor 10 h through the connection part 9 and the supply line 4 rearwardly to the electronic control device 13, for the setting of the desired operational data.
In the case of the exemplary embodiment according to FIGS. 12 to 14, the identification device 10 for an instrument 2 is provided in that in the region of the coupling 8 there is mounted a rotary part, which in the case of the exemplary embodiment is a drive shaft 2 c which is rotatably mounted in a drive channel of the instrument 2. The rearward end of the drive shaft 2 c is coupled by means of a plug-in coupling 2 d with a drive shaft section 9 a rotatably mounted in the connection part 9, which drive shaft section may be for example the drive shaft of the motor M. With this configuration there is provided a sensor 10 k which is held in the connection part 9, at the end face side of the coupling pin 8 b. On the drive shaft 2 c of the instrument 2 there is located a sender element 10 a of ferromagnetic material which extends over an angle Φ and has a height which reduces over the angle Φ. It has—seen in an evolved view—the form of a ramp. The sender element 10 a passes the sensor 10 k upon rotation the drive shaft 2 c. The sensor 10 k is for example a coil in which the sender element 10 a, moving past the coil, generates a potential U dependent upon the speed of rotation and the direction of rotation of the drive 2 c.
There is now possible a coding of the instrument 2 through selection of the starting and finishing height of the sender element 2 a and/or through selection of the angle Φ over which the sender element extends, in other words, a coding is possible through the selection of a certain ramp form.
In FIGS. 14a and 14 b there are illustrated the output signals of the sensor element 10 k, as potential U in dependence upon time. Upon rotation of the drive shaft 2 c in FIG. 13 there arise potential pulses.
In FIG. 14a, the potential pulses are shown for leftwards rotation of the drive shaft 2 c. In this case, the ramp has in relation to the sensor 10 k a rising form, with the consequence that positive potential pulses are generated.
In FIG. 14b there are shown the potential pulses in the case of leftwards rotation of the drive shaft. Since here the ramp has in relation to the sensor 10 k a falling form, the potential pulses are negative.
In both Figures the pulses have a temporal duration t1 and a temporal separation t2. The periodic duration is T. The relationship between the angle Φ shown in FIG. 13 and the times indicated in FIG. 14a and 14 b is provided by the formula:
Φ=360°*t 1 /T
The speed of rotation n of the drive shaft 2 c is n=1/T. Through measurement of t1 and t2 or T the coding angle Φ can be deduced.
The polarity of the potential pulses provides information concerning the direction of rotation (to the left or to the right) of the drive shaft 2 c.
With the exemplary embodiment according to FIGS. 15 and 16 the coding 10 a is in each case alterable. The coding 10 a is not only able to make available certain data which is readable by the reading device 10 b, but the coding 10 a can be changed with regard to the data stored therein, and this with data which is transferred thereto from the electronic control device 13. Here there may be involved operational data, for example at least one operational program predetermined by the manufacturer or produced by the user. Other information may also be involved, for example information which relates to the operation of the instrument 2 and/or the patients to be treated and/or the treatment of the instrument in the sense of maintenance procedures. Thereby, the reading device 10 b is at the same time a data transmitter and a receiver 10 o and the coding 10 a is alterable through a transfer of data from the data transmitter 10 o and preferably constituted by means of a memory element 10 p for the overwriting of its data with the data transferred from the data transmitter 10 o. FIGS. 15 and 16 show by way of example two exemplary embodiments for such a data transfer device with which the data can be selectively transferred that is called up and again read in, both in the one and also the other direction between the electronic control device 13 and the memory element 10 p.
[0069]FIG. 15 shows an exemplary embodiment having mechanical contact means 10 q between the data receiver and transmitter 10 o and the memory element 10 p. The individual electrical contacts are, for reasons of simplicity, not illustrated. FIG. 16 shows a contact-less data transfer between the data receiver and transmitter 10 o and the memory element 10 e. The data transfer may be effected for example electromagnetically or inductively. The memory element 10 p may be constituted by means of a transponder, namely a receiver-transmitter apparatus, which works in accordance with a query-response system. In the case of the data receiver and transmitter 10 o there may be involved a corresponding transponder. In both cases there are involved memory elements which are in each case constituted by a prefabricated, in particular pin-like components and which are put in place in a recess, corresponding to the recesses 21, 22.
With all above-described exemplary embodiments it is advantageous to arrange the sensitive components, here the reading device 10 b, on the connection part 9 or on the coupling pin 8 b projecting from this, and to arrange the coding on the instrument 2. Through this, the less sensitive parts of the identification device 10 are arranged on the instrument 2 which in the case of cleaning, disinfection and/or sterilisation is subject to significant demands, in particular temperatures. Beyond this, the electronic control device 13 is connected by means of at least one suitable data line with the reading device 10 b or with the data receiver and transmitter 10 o.
The sterilisation apparatus 31 according to FIG. 3 has, in a housing 33, a sterilisation chamber 34 which can be opened and closed by means of a non-illustrated door, so that an instrument 2 to be sterilised can be brought into and placed in the sterilisation chamber 34, for example on a repository or bowl 35. In order to be able to be used with instruments 2 in accordance with the above-described configurations according to FIGS. 6 to 11 and 15 and 16, there is associated with the sterilisation apparatus 31 a reading device 10 b or a data receiver and transmitter 10 o , which may be located within or outside the sterilisation chamber 34 and can identify the instrument 2 on the basis of the coding 10 a and carries out the supply measures necessary for the disinfection, for which purpose there is included for example the heating of the sterilisation chamber 34 to the necessary sterilisation temperature, for example at least 135°, and if appropriate also the generation of an over-pressure or under-pressure in the sterilisation chamber 34. With the reference numbers 36 and 37 there are schematically associated a supply apparatus for making available the sterilisation media and an electronic control apparatus having an evaluation circuit for the read data and for controlling the sterilisation measures. The data read by the reading device 10 b or by the data receiver 10 o is delivered to the control device 37 for the purpose of recognition of the instrument 2 and control of the sterilisation measures.
As for the maintenance apparatus 13, the maintenance apparatus 32 also has in each case a reading device 10 b or a data receiver and transmitter 10 o associated with the coupling parts 8 b 1 belonging thereto, which recognise the introduced or coupled instrument 2 on the basis of a coding 10 a or data storage and pass on the data to the control device 37 for controlling the supply apparatus 36 and for carrying out the maintenance measures.
These advantages and measures apply not only for a treatment apparatus according to FIG. 1 and 2 but also for a maintenance apparatus 32 for the carrying out of cleaning and/or disinfection and/or sterilisation measures. The configurations in accordance with the invention make possible the recognition and fulfilment of the following requirements of the instrument or instruments 2.
a) Which instrument 2 is involved?
b) What requirements does the instrument 2 present? For example, operational data such as speed of rotation, torque; which operating medium (air, water, electrical current etc.) is necessary?
c) In what condition is the instrument? For example how many hours of operation has the instrument already run for; is the instrument 2 clean or disinfected or sterilised or maintained?
The requirements a) and b) are recognised by the individual or common electronic control device in each case by means of comparison and evaluation of the recognised identification data with the data stored in the electronic control device. The requirement c) is fulfilled in that the operational data concerned is determined and registered and thus the registered data concerned represents the current condition of the instrument 2. Through a continuing registration of data there can also be registered the operational development and thus not only particular operational functions of working and of maintenance. Specific operational procedures or data can be so controlled in dependence upon previous operational procedures or stored data that a certain operational procedure can only be affected if a previous operational procedure has taken place or a particular operational condition has been attained, which is registered or stored by means of data. If for example an instrument 2 has not been maintained, the control device recognises this defect on the basis of the lack of relevant data and it blocks the subsequent operational procedure or indicates this fault by means of a warning signal or registers this fault. If for example an instrument 2 has not been maintained or has been insufficiently maintained, if for example the sterilisation temperature and/or sterilisation time do not correspond to the desired value, the control device recognises this at the latest upon coupling of the instruments to the supply apparatus 3, whereby the control device can block the use or at least indicate the fault.
For example, instrument A was subject to maintenance in maintenance apparatus 32 on Jan. 1, 2001 at 10.00 hours. Instrument A was sterilised in sterilisation apparatus 31 on Jan. 16, 2001 at 10.05 hours. Instrument A was operated for a total of 5 minutes on working apparatus 1 (patient 4) on Oct. 16, 2001 at 11.00 hours. Through this not only the operational procedure can be determined but also faults can be determined for example by means of a fault report which the associated control device derives or recognises upon coupling of the non-sterilised instrument 2.
