【 要旨 】 生命維持管理装置(装置)の保守管理を施行する場合の経済性について,修理(定期オーバーホール:OH)を臨床工学技士(技士)が行うものと,外部委託で行うもので比較した.対象の装置は血液透析用患者監視装置で,技士施行のコストは当院でのOH平均所要時間と技士の時間給より計算した.外部委託のコストは業者が同様の部品を交換した場合の標準的なコストで計算した.コストは部品代を除き1台当り技士14,000円,業者119,000円で,技士施行での経済的な優位性が確認できた.また,技士自らOHを施行するには必然的に装置の動作,構造および機構に熟知する必要がある.このため臨床使用での安全性が格段に向上する.経済性とともに治療の安全性の面からもOHの実施は必須であると思われた.質の高い保守点検と修理を低コストで行うことを社会が要求している今,われわれ技士はさらに業務の拡大を行い,良質の医療を提供しなければならないと考える.
Theme Maintenance and Repair of Dialysis Machines
Title Clinical engineer and maintenance of the dialysis console -- Maintenance control ; economic considerations
Author Junji Uchino ME Department, Mihama Hospital
[ Summary ] Concerning the economic features of maintenance control of life sustaining equipment (herein ater device), the repair (regular overhaul; OH) made by a clinical engineering technologist (technologist) was compared with that consigned to an outside source. The device was a monitoring apparatus for hemodiaiysis patients. The cost of repair by our technologist was calculated from the mean OH time and the hourly wage of the technician. The cost of repair by an outside source was calculated on the basis of the standard cost for replacement of a similar part by that source. Excluding the part cost, the cost per device was 14,000 YEN when the repair was done by our technologist against 119,000 YEN by an outside source, indicating an economic advantage in the former case. For a technologist to OH a device by himself, he has to fully understand the motions, structure and mechanism of the device in question. This will lead to improved safety in the clinical application of the device. OH by our technologist is assumed to be essential not only because it is more economical but also in view of clinical safety. High quality inspection and maintenance,coupled with low cost repair, which are presently in demand, should prompt technologists to expand their range of activities aimed at providing high quality medical care.
