本発明は顎関節前および咬合音の検出装置に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for detecting temporomandibular joint and occlusal sounds.
従来、顎関節前によって顎関節の異常を検出できること
は知られていたが、とｒｔを表示あるいは１リントする
検出装置がなく、その実現が侍ぢ望まれていた。Conventionally, it has been known that abnormalities in the temporomandibular joint can be detected by looking at the front of the temporomandibular joint, but there is no detection device that displays or prints rt, and the realization of such a device has been desired.
そこで本発明は、構成の大半を共用して咬合音と顎関節
前を選択的に検出しうる検出装置を提供するものである
。Therefore, the present invention provides a detection device that can selectively detect occlusal sounds and temporomandibular joints by sharing most of the configuration.
以下、本発明の一実施例を図面に基づいて説明する。１
はピンクアンプ装置で、その検出部１ ａ。Hereinafter, one embodiment of the present invention will be described based on the drawings. 1
is a pink amplifier device, and its detection section 1a.

らなる。７はサンプリングパルス発生回路等からなる。1b is designed to pink-amplify sounds in front of the temporomandibular joints and occlusion by making elastic contact near the left and right temporomandibular joints. 2.5 is a filter with a variable passband, 4.5 is an amplifier, and 6 is a storage control circuit, which includes an A/D conversion circuit, a sampling circuit, a storage circuit, and the like. 7 consists of a sampling pulse generation circuit and the like.

よびプリントする表示装！およびプリンタである。7 is a sampling pulse generation circuit, which generates 211.50. 1'00, 20tl, 20
One of the sampling pulses of 004s is iA selected. 9.10 is a display device that displays and prints the waveforms of the pretemporomandibular joint and occlusal sounds! and a printer.

せるためにサンプリングパルスの周期を切シ換えるもの
である。With the above configuration [j4, the occlusal sound becomes pink amplifier when the pink amplifier device 1 is fully attached and the upper and lower teeth are brought into occlusion, and the front of the temporomandibular joint becomes pink amplifier when the hip joint is opened and closed without occlusion. be done. The time before the temporomandibular joint disappears is approximately 1 second, which is 10 to 50 times longer than the occlusal sound, and the period of the sampling pulse is switched in order to store the entire waveform in a common memory circuit. It is.

Select one of the 200 μs sampling pulses. The entire waveform of the occlusal sound is kept within the full scale by a sampling pulse of 200 μs, and as the period of the sampling pulse becomes shorter, a part of the waveform is enlarged and displayed.
;e,b・By the way, when the 2000 μs sampling pulse is selected, the filter 2.5 operates as an 80 H2 bypass filter, and when any other sampling pulse is selected, the filter 2.3 operates as a 200 H2 bypass filter. H
It is set to operate as a bypass filter for z. As a result, high-frequency noise that can be superimposed on each waveform is removed, and waveforms that are faithful to the original sound are displayed and recorded.
但し、フィルタ２．５の周波数は必ずしも切シ換える必
要はなく、例えば７．８０ Ｈｚ に固定しておいても
よい。However, the frequency of the filter 2.5 does not necessarily need to be switched, and may be fixed at, for example, 7.80 Hz.

構成の大半を共用しつ咬合音をも検出することができる
。As described above, according to the present invention, the pre-temporomandibular joint can be detected and can greatly contribute to the diagnosis of temporomandibular joint abnormality Ω. Furthermore, by simply switching the period of the sampling pulse, it is possible to detect occlusal sounds while using most of the components in common.
