Abstract: 現在のポータブルトイレは毎回し尿の廃棄と便槽の洗浄が必要なため必ず介護者を必要とし,介護者にも多大な労力と精神的な苦痛を強要していた.近年,便槽内でおが屑とし尿を一定の環境下で攪拌し分解する微生物分解型トイレ(以下,バイオトイレ)が開発された.我々はバイオトイレを介護の場に導入するため現在市販中の3機種の機能を比較し,小型軽量で排気管が不要かつ本体価格,維持費とも安価でメンテナンスが不要な1機種を実際に病院内で使用した.その結果し尿の取替えが不要となるため介護の省力効果は極めて高く衛生的で上下水道も不要であった.おが屑の細菌培養結果も通常では病原性のない菌のみであった. 欠点は堆肥のような臭いがあることであった.バイオトイレはし尿の廃棄が不要で被介護者の自立を助け介護者の肉体的,精神的負担を軽減し,衛生的かつ費用対効果も高い.今後臭いの面を改良すれば将来有用な福祉機器になると考えられた. / Portable chamber pot-type toilet bowls are now widely in use. However, when using these devices help from a care provider is still required because the excrement still needs to be disposed of and the toilet cistern must still be cleaned after each use. Recently, a biotoilet bowl has been developed, which is able to completely degrade excrement. This is accomplished by mixing the excrement with a microorganism carrier in the toilet. We investigated the function of the biotoilets commercially available now. Each of these three types has sufficient excrement disposing ability with a capacity of 2 kg/day. One is heavy in weight and requires an exhaust pipe. We used one of the remaining two in a hospital setting. The patient who used the toilet, two fellow patients in the same room, two nurses, and two doctors, were all asked questions concerning the following points : odor, noise, size, stability, ease in handling, and the excrement disposal procedure. Their answers show that the biotoilet is useful and effective because no troublesome procedure is needed for excrement disposal, and it is also helpful in promoting a self-supporting attitude in those patients who use one. It reduces physical and mental stress and lightens the burden on the care receivers and it also provides a highly hygienic outcome and is cost effective. The bacteria culture results revealed only nonpathogenic bacteria. The only disadvantage is odor. If the odor problem can be solved and efforts can be made to promote its wider social recognition, the biotoilet will likely become a very useful tool in the social welfare field.
