Description
i 146791in 146791
Opfindelsen angår et kæbeortopædisk apparat af den i krav l's indledning angivne art. Fra US-patentskrift 3 885 310 kendes et ekstra-oralt kæbeortopædisk apparat med en holdebøjle, der er lukket bag ved patientens hoved ved hjælp 5 af et bånd, og som gennem mundåbningen er forbundet med selve det i munden anbragte kæbeortopædiske apparat. På båndet er anbragt en tidsmåler, som aktiveres, når spændingen i båndet når op på en forudbestemt værdi. Tidsmåleren består af en impulsgiver og en tæller. Tællerens vis-10 ning skal give oplysning om det tidsrum, i hvilket patien ten har båret apparatet, og til dette tidsrum skal der tages hensyn ved bedømmelsen af behandlingsresultatet. Ved dette kendte apparat kan en afbryder sluttes på enkel vis ved, at hovedbåndet strækkes, uden at apparatet 15 bæres. Kæbeortopædiske apparater er som bekendt hoved sageligt beregnet til børn, og disse vil være fristet til at undlade at bære apparatet i munden, fordi dette er ubehageligt, og at forfalske den af tælleren viste bæretid ved aktivering af afbryderen på den i det foregå-20 ende angivne måde. Det kendte apparat har således den mangel, at den behandlende tandlæge ikke kan stole på tællerens visning.The invention relates to a jaw orthopedic apparatus of the kind set forth in the preamble of claim 1. US Patent 3,885,310 discloses an extra-oral jaw orthopedic apparatus with a holding bracket closed behind the patient's head by means of a band and connected through the mouth opening to the oral orthopedic device itself. On the tape is a timer which is activated when the voltage in the tape reaches a predetermined value. The timer consists of an encoder and a counter. The display of the counter must give information about the period during which the patient has carried the apparatus, and this period must be taken into account when assessing the treatment result. In this known apparatus, a switch can be simply closed by stretching the headband without the apparatus being worn. Jaw orthopedic appliances are, as is well known, mainly intended for children, and these will be tempted to fail to carry the device in the mouth because this is uncomfortable and to falsify the carrying time shown by the counter by activating the switch on the previous end. specified way. Thus, the known apparatus has the disadvantage that the treating dentist cannot rely on the counter's display.
Det er endvidere kendt på et kæbeortopædisk apparatets formlegeme at anbringe en tidsmåler bestående af et 25 Coulombmeter, jfr. DE-offentliggørelsesskrift 2 614 519.It is further known to place on the mold body of a jaw orthopedic device a timer of a 25 Coulomb meter, cf. DE Publication Publication 2 614 519.
Coulombmete ret fastgøres sammen med apparatets formlegeme i patientens mund og består af en glasbeholder, som indeholder kviksølv og en elektrolyt. Passerer der strøm gennem Coulombmeteret, bevæges elektrolytmængden 30 langsomt gennem kviksølvet. På skillestedet mellem de to kviksølvsøjler kan produktet af strømstyrke og tid aflæses. Coulombmeteret er indskudt i et seriekredløb indbefattende en fugtighedsomskifter og en temperatur-omskifter. Ved denne målemetode måles bæretiden ved 35 konstatering af produktet af strømstyrke og tid. Anbrin- 146791 2 gelsen af et sådant Coulombmeter i mundhulen er imidlertid farlig, fordi der ved en eventuel beskadigelse af glasbeholderen ikke blot spredes glassplinter i munden men også kviksølv og elektrolyt.The coulomb-shaped dish is attached together with the mold body of the device in the patient's mouth and consists of a glass container containing mercury and an electrolyte. If current passes through the Coulomb meter, the amount of electrolyte 30 is slowly moved through the mercury. At the point of separation between the two mercury columns, the product of current strength and time can be read. The coulomb meter is inserted into a series circuit including a humidity switch and a temperature switch. In this measurement method, the carrying time is measured by determining the product of current and time. However, the placement of such a Coulomb meter in the oral cavity is dangerous because, in case of possible damage to the glass container, not only glass splinters are spread in the mouth but also mercury and electrolyte.
5 Opfindelsen har til formål at afhjælpe ovennævnte mangler ved den kendte teknik og tilvejebringe et sådant apparat med en tidsmåler, der er velegnet til orale kæbeortopædiske apparater med en ganeplade, og som ikke er til gene eller fare for patienten. Apparatets afbryder skal 10 være således anbragt, at den ikke påvirkes ved apparatets reguleringsfunktion. Ovennævnte formål opnås ved det i krav l's kendetegnende del angivne. Ved placeringen af den elektroniske tidsmåler i et hulrum i apparatets form-legeme beskyttes tidsmåleren mod mekanisk beskadigelse.The invention has for its object to overcome the aforementioned shortcomings of the prior art and to provide such an apparatus with a timer suitable for oral jaw orthopedic devices with a palate and which is not to the detriment or danger of the patient. The switch of the device 10 must be so arranged that it is not affected by the control function of the device. The above object is achieved by the characterizing part of claim 1. By placing the electronic timer in a cavity in the mold body of the apparatus, the timer is protected from mechanical damage.
15 Selv hvis tidsmåleren skulle blive beskadiget, kan det te ikke medføre nogen risiko for patienten, fordi tidsmåleren i apparatet ifølge opfindelsen ikke indeholder giftige eller farlige substanser. Den elektroniske tidsmåler sikrer en meget eksakt bestemmelse af den 20 tid, der interesserer tandlægen, så at denne meget nøj agtigt kan vurdere behandlingsresultatet. Miniaturise-rede elektroniske konstruktionsdele og batterier er disponible med tilstrækkelig små dimensioner, så at anbringelsen af tidsmåleren i apparatets formlegeme 25 ikke medfører nogen væsentlig forøgelse af formlegemets dimensioner.Even if the timer should be damaged, the tea may not pose a risk to the patient because the timer in the apparatus of the invention does not contain toxic or dangerous substances. The electronic time meter ensures a very precise determination of the 20 time that interests the dentist, so that it can accurately assess the treatment result. Miniaturized electronic structural members and batteries are available with sufficiently small dimensions so that the placement of the timer in the mold body of the apparatus does not substantially increase the dimensions of the mold body.
Ved det i krav 2 angivne opnås en vis teknisk forenkling af apparatet. Da det ortopædiske apparat ifølge opfindelsen skal bæres i munden praktisk taget i hele 30 behandlingstiden, kræves der en mindre tæller med et mindre lager og en mindre indikator, når man måler og konstaterer den tid, i hvilken apparatet ikke bæres i munden, end når bæretiden måles, fordi bæretiden er 3 1487 91 væsentlig længere end den tid, i hvilken apparatet ikke befinder sig i patientens mund. Det konstateres ved hjælp af afbryderen, om apparatet bæres eller ikke. Afbryderen bør være således anbragt, at den ik-3 ke kan manipuleres, når det kæbeortopædiske apparat er taget ud af munden.In the claim 2, a certain technical simplification of the apparatus is achieved. Since the orthopedic device according to the invention is to be carried in the mouth practically for the entire treatment time, a smaller counter with a smaller stock and a smaller indicator is required when measuring and finding the time during which the device is not carried in the mouth than when the carrying time is measured because the carrying time is substantially longer than the time during which the apparatus is not in the patient's mouth. It is ascertained by means of the switch whether the device is worn or not. The switch should be positioned so that it cannot be manipulated when the jaw orthopedic device is removed from the mouth.
Ved det i krav 3 angivne opnås, at tidsmåleren er let at aflæse, idet tælleren til aflæsning ikke skal sluttes til et eksternt aflæseapparat.In accordance with claim 3, it is achieved that the time meter is easy to read, since the reading counter does not have to be connected to an external reading device.
10 Ved den i krav 4 kendetegnede udførelsesform for appa ratet opnås den fordel, at de elektriske komponenter kan anbringes fordelt på flere steder og indkapsles på disse, så at der til komponenterne ikke kræves noget fælles hus, som måtte have betydelige dimensioner. På 15 denne måde kan komponenterne bekvemt finde plads i et som ganeplade udformet formlegeme.In the embodiment of the apparatus characterized in claim 4, the advantage is obtained that the electrical components can be arranged distributed in several places and enclosed thereon, so that no common housing is required for the components having significant dimensions. In this way, the components can conveniently find space in a mold body designed as a palate plate.
Ved den i krav 5 angivne udførelsesform for afbryderen aktiveres og inaktiveres tælleren direkte af apparatets tandreguleringsdel. Når apparatet ganske vist bæres men 20 ikke påvirker tænderne med et tilstrækkeligt stor regu leringstryk, registreres dette ikke som bæretid.In the embodiment of the switch according to claim 5, the counter is activated and deactivated directly by the device's tooth control part. Although the apparatus is worn but 20 does not affect the teeth with a sufficiently large control pressure, this is not recorded as wear time.
Ved den i krav 6 angivne udførelsesform kan bæretiderne og de inaktive tider indikeres på samme måde som kørselstiderne og stilstandstiderne vises ved en fart-25 skriver. Denne differentierede tidsmåling er særlig velegnet til videnskabelige undersøgelser til konstatering af bæretidernes indvirkning på tandreguleringen.In the embodiment of claim 6, the carrying times and the idle times can be indicated in the same way as the running times and downtime are displayed by a speed writer. This differential time measurement is particularly well suited for scientific studies to determine the impact of wear times on tooth regulation.
Endelig opnås ved det i krav 7 angivne, at en eventuel simulering af bæretider vanskeliggøres ved en man-30 gedobling af de betingelser, under hvilke afbryderen aktiveres.Finally, it is achieved by the requirement of claim 7 that any simulation of load times is hampered by a maneuvering of the conditions under which the switch is activated.
4 14E791 I det følgende forklares opfindelsen nærmere ved hjælp af tegningen, hvor fig. 1 viser anbringelse af til en tidsmåler hørende elementer i det kæbeortopædiske apparat ifølge opfin-5 delsen, fig. 2, 3 og 4 viser snit efter linien henholdsvis II-II, III-III og IV-IV i fig. 1, fig. 5 skematisk viser et koblingsdiagram for tidsmåleren , 10 fig. 6 viser et tidsdiagram som eksempel på en mulig hed for aftegning af længden af på hinanden følgende bære- og ikke-bæretider, fig. 7 perspektivisk viser en kapsel for et batteri, fig. 8 perspektivisk viser kapselen tilsluttet et eks-15 ternt aflæsningsapparat, og fig. 9 perspektivisk viser en kapsel for en tidsmåler med eget talvisningsværk.In the following, the invention is explained in more detail with reference to the drawing, in which fig. Figure 1 shows the placement of elements of a time meter in the jaw orthopedic apparatus according to the invention; 2, 3 and 4 show sections along the line II-II, III-III and IV-IV in FIG. 1, FIG. 5 is a schematic diagram of a timing diagram for the meter; FIG. 6 shows a time diagram as an example of a possibility of plotting the length of consecutive carrier and non-carrier times; FIG. 7 is a perspective view of a capsule for a battery; FIG. 8 is a perspective view of the capsule connected to an external reading apparatus; and FIG. 9 is a perspective view of a capsule for a timer with its own numerical display.
I fig. 1 er vist en overkæbe 10, hvis form skal ændres med et kæbeortopædisk apparat 11. Tænderne er betegnet 20 med 12. Det kæbeortopædiske apparat består af mindst ét plastformlegeme 13, til hvilket er fastgjort forbindelsestråde 14, som helt eller delvis griber rundt om tænderne. Der kan også findes flere plastformlegemer, som er forbundet med hinanden ved hjælp af forbindelses-25 tråde. Apparatets form er afpasset efter formen af den pågældende kæbe og de fejl, der skal rettes.In FIG. 1, an upper jaw 10 is shown, the shape of which is to be changed by a jaw orthopedic device 11. The teeth are designated 20 by 12. The jaw orthopedic device consists of at least one plastic molding body 13 to which is attached connecting wire 14, which grips all or part of the teeth. There are also several plastic molding bodies which are connected to each other by means of connecting wires. The shape of the device is adapted to the shape of the jaw in question and the errors to be corrected.
Fig. 2 viser plastformlegemet 13, der trykker imod en 5 146791 tand 12, og som i et første hulrum 15 indeholder et miniaturebatteri 16. Hulrummet 15 er lukket med en plade, så at det er afspærret udefra.FIG. 2 shows the plastic mold body 13 which presses against a tooth 12 and which in a first cavity 15 contains a miniature battery 16. The cavity 15 is closed with a plate so that it is locked from the outside.
På fig. 3 ses en trykfølsom afbryder 17, der trykker 5 mod tanden 12 og aktiveres af denne. Afbryderen 17 befinder sig i den yderste ende af formlegemet 13, som trykker mod tanden.In FIG. 3, a pressure-sensitive switch 17 is shown which presses 5 against the tooth 12 and is activated by it. The switch 17 is located at the outermost end of the mold body 13 which presses against the tooth.
I endnu et hulrum 19 i formlegemet 13 er tidsmåleren 18 anbragt. Dette hulrum er ligeledes lukket mod yder-10 siden. Batteriet 16, den trykfølsomme afbryder 17 og tidsmåleren 18 er forbundet med hverandre ved hjælp af elektriske ledninger 20'.In yet another cavity 19 in the mold body 13, the timing meter 18 is disposed. This cavity is also closed to the outer side. The battery 16, the pressure-sensitive switch 17 and the timer 18 are connected to each other by means of electrical wires 20 '.
På fig. 5 er skematisk vist det elektriske koblingssystem for tidsmåleren i form af et blokdiagram. Til bat-15 teriet 16 er tidsmåleren 18 og afbryderen 17 koblet i serie. Når afbryderen 17 er lukket, startes tidsmåleren 18, der består af en impulsgiver 20, som, når den er tilsluttet strømforsyningen, danner impulser med en bestemt frekvens. Disse impulser tilføres en tæller 21, 20 der tæller disse impulser, og som også oplagrer det til enhver tid værende talresultat, når afbryderen 17 igen åbnes. Tallet i tælleren 21 er derfor et mål for den tid, i hvilken afbryderen 17 har været sluttet.In FIG. 5 is a schematic representation of the electrical switching system of the timing meter in the form of a block diagram. To the battery 16, the timer 18 and the switch 17 are connected in series. When the switch 17 is closed, the timer 18 is started, which consists of an encoder 20, which, when connected to the power supply, generates pulses at a certain frequency. These pulses are applied to a counter 21, 20 which counts these pulses and which also stores the numerical result at all times when the switch 17 is opened again. The number in the counter 21 is therefore a measure of the time in which the switch 17 has been closed.
Tidsmåleren 18 udføres mest hensigtsmæssigt som et in-25 tegreret modul.The timer 18 is most conveniently executed as an integrated module.
Tidsmåleren 18 kan være udført således, at den kan udtages af hulrummet 19 og tilsluttes et aflæseapparat 22 til påvisning af tallet i tælleren 21. Tidsmåleren kan også forblive i kapselen og tilsluttes et aflæse-30 apparat, hvilket under visse omstændigheder kan være nemmere for tandlægen.The timer 18 may be designed so that it can be removed from the cavity 19 and connected to a reading apparatus 22 for detecting the number in the counter 21. The timer may also remain in the capsule and be connected to a reading apparatus, which may be easier for the dentist in certain circumstances. .
146791 6 Når tidsmåleren indeholder flere tællere, som kan aktiveres efter hinanden, og som afvekslende viser bære-tiden og ikke-bæretiden, kan de opfylde en registreringsfunktion i overensstemmelse med fig. 6. Når en 5 sådan tidsmåler aflæses, kan man gengive den samlede bære-rytme mellem to behandlingsterminer ved aflæsning af lagrene, f.eks. med et tilsluttet skriveudstyr eller en hurtigtrykker. På fig. 6 er bæretiden betegnet med "1" og ikke-bæretiden med "0". Tidsmåle-10 ren kan indeholde et ur, hvis tidsvisning overtages af et lager ved hver aktivering af afbryderen 17. På denne måde oplagres tidspunktet for udtagning henholdsvis indsætning af apparatet. Disse data kan derpå afgives til aflæsningsapparatet, henholdsvis et andet appa-15 rat til videre forarbejdning.When the timer contains several counters which can be activated one after the other and which alternately show the carry time and the non-carry time, they can fulfill a recording function according to FIG. 6. When a 5 such timer is read, one can reproduce the overall carrier rhythm between two processing terminals by reading the bearings, e.g. with a connected typewriter or a fast printer. In FIG. 6, the carrying time is denoted by "1" and the non-carrying time is "0". The timer can include a clock whose timing display is taken over by a memory at each activation of the switch 17. In this way, the timing of removal and insertion of the apparatus is stored, respectively. This data can then be delivered to the reading apparatus or another apparatus for further processing.
Fig. 7 viser en beholder 23, der er lukket væsketæt med et låg 24, og som indeholder batteriet 16. I bunden af beholderen og på låget findes kontaktpoler 25 til etablering af kontakt med polerne på batteriet 16.FIG. 7 shows a liquid-tight container 23 with a lid 24 containing the battery 16. At the bottom of the container and on the lid are contact poles 25 for establishing contact with the poles on the battery 16.
20 Kontaktpolerne 25 er med ledninger (ikke vist) forbun det med andre elektriske byggedele. Ved indskruning af kapsellåget 24 presses de mod batteripolerne.20 Contact terminals 25 are connected to other electrical components with wires (not shown). When screwing on the cap 24 they are pressed against the battery terminals.
En tilsvarende beholder 26 med låg 27 tjener til opbevaring af tidsmåleren 18. Denne beholder er ligeledes 25 lukket væsketæt. Tidsmåleren 18 har tilslutninger, til hvilke aflæseapparatet 22 kan tilsluttes, for at tællerens indhold kan aflæses. På denne måde kan man ved aflæsning af tælleren i tandlægeklinikken fastslå det tidsrum, hvori apparatet er blevet båret.A corresponding container 26 with a lid 27 serves to store the timing meter 18. This container is also 25 closed in liquid tightness. The timer 18 has connections to which the reader 22 can be connected in order to read the contents of the counter. In this way, when reading the counter in the dental clinic, the length of time during which the device has been carried can be determined.
30 I fig. 9 er vist en beholder, som er lukket med et låg 30, og som indeholder en tidsmåler 18 med miniaturedi-gitalvisning 31. På denne måde kan den tid, apparatet er blevet båret, vises og uden tilslutning til et eks-In FIG. 9, a container closed with a lid 30 is shown which contains a timer 18 with miniature digital display 31. In this way, the time the apparatus has been carried can be displayed and without connection to an external display.
