PROBLEM TO BE SOLVED: To provide an oral cavity mucosa collecting device for collecting the mucosa in the oral cavity, wherein a collected mucosa collecting member is housed and transported sanitarily and simply, bacteria at the housed mucosa collecting member are prevented from being propagated, and circulation management is so easy that a time-series history is grasped reliably.SOLUTION: The oral cavity mucosa collecting device 1 is composed of upper and lower slender cases 10b and 10a and the mucosa collecting member 20. The mucosa collecting member 20 is provided partially projecting at the upper side of the end in the lower case 10a. The case is formed in an upward foldable manner with a rotating hinge 12 provided at a part divided nearly at the center of a longitudinal direction. When the case is folded upward, the mucosa member is housed in the case. The upper case 10b houses a desiccating agent, and its outer surface is provided with a bar code symbol.COPYRIGHT: (C)2008,JPO&INPIT【課題】口腔内の粘膜を採取する口腔内粘膜採取器で、採取された粘膜採取部材の収納と輸送が衛生的で簡便で、かつその収納された粘膜採取部材の細菌の繁殖を防止し、さらに流通管理が容易で時系列的な履歴が確実に把握できる口腔内粘膜採取器の提供にある。【解決手段】細長の上下部ケース10b、10aと粘膜採取部材20とからなり、該粘膜採取部材20は下部ケース10a内の端部上方に一部突出するように設けられ、ケースは、長手方向の略中央で分割された部分に設けられた回転する蝶番12により上方へ折り畳み自在に成形され、該上方への折り畳みによって前記粘膜部材が前記ケース内に収納され、上部ケース10bには乾燥剤が収納され、外側表面にはバーコードシンボルが施されている内粘膜採取器1である。【選択図】図2
