PROBLEM TO BE SOLVED: To provide a medical device which is low in cost and can change appearance easily without preventing the promotion of miniaturization.SOLUTION: In a medical device 1 for measuring the condition of a living body, a recess 8 is prepared on the exterior surface (surfaces 6 and 7) of the casing 2. A patch member 3 is worn on the inside of the recess 8. When a display screen 4 which displays a measuring result is prepared in the casing 2, it is preferred that the surfaces 6 and 7 are located next to a surface 5 where the display screen 4 is prepared. The patch member 3 has an adhesive layer, a printed layer, and a nonslip layer which is formed by resin material or rubber material. It is preferred that the adhesive layer, the printed layer, and the nonslip layer are layered in order.COPYRIGHT: (C)2012,JPO&INPIT【課題】低コストで、小型化の促進を妨げることなく、容易に外観を変化させ得る医療機器を提供する。【解決手段】生体の状態を計測するための医療機器1において、その筐体2の外面(面6及び7)に凹部8を設ける。凹部8の内側に、貼付部材3を貼付する。筐体2に、計測結果を表示する表示画面4が設けられる場合は、面6及び7は、表示画面4が設けられた面5に隣接しているのが好ましい。貼付部材3は、粘着材層と、印刷層と、樹脂材料又はゴム材料によって形成された滑り止め層とを備え、粘着材層、印刷層、及び滑り止め層は、順に積層されているのが好ましい。【選択図】図1
