【考案の詳細な説明】 本考案は綿棒の支持装置に関する。[Detailed explanation of the idea] The present invention relates to a cotton swab support device.
歯のう蝕の羅患性ないし活動性を予測する歯の
う蝕活動性試験として、口腔内細菌の糖利用によ
る酸の産生をう蝕活動性の指標とした試験法があ
る。この試験法の代表的なものとして、スナイダ
ー法、カリオスタツト法などがある。 As a dental caries activity test for predicting the prevalence or activity of dental caries, there is a test method that uses the production of acid by the use of sugar by oral bacteria as an indicator of caries activity. Representative examples of this test method include the Snyder method and the Cariostat method.
カリオスタツト法は、綿棒で採取したサンプル
である歯垢を適切な倍地であるPH指示薬を含む試
験液中で24時間乃至48時間培養することにより、
歯垢のう蝕誘発性細菌による酸の産生量を指示薬
の色の変化を観察することによつて判定する。 The cariostat method involves culturing dental plaque, which is a sample taken with a cotton swab, for 24 to 48 hours in a test solution containing a pH indicator, which is an appropriate medium.
The amount of acid produced by cariogenic bacteria in dental plaque is determined by observing the change in the color of the indicator.

に、従来はこのような目的を達成する綿棒の支持
装置はなかつた。 These methods determine the amount of acid produced by visually observing changes in the color of the test solution, so if the change in color of the test solution is subtle, it may be due to the brightness of the room where the observation is performed or individual differences. However, the problem was that the judgment was inaccurate. For this reason, in order to make accurate measurements, it is effective to perform automatic measurements using a measuring device that uses a photoelectric sensor, but the cotton swab soaked in the test liquid gets in the way, so it is not possible to use the transmitted light method or the reflected light method. There was a problem that a type of photoelectric sensor could not be used. Therefore, in order to form an optical path, it is necessary to hang the cotton swab so that the cotton part of the swab is higher than the bottom of the container storing the test liquid, and in order to perform various tests, Swabs should be easily replaceable. However, conventionally, there has been no cotton swab support device that achieves this purpose.
