Title (EN) MEDICAL SHEET
(FR) FEUILLE MÉDICALE
(JA) 医療用シート
Abstract:
(EN) [Problem] To provide: a medical sheet with which a surface (a portion) subjected to ion bombardment, and a surface (a portion) which has not been subjected to ion bombardment can be distinguished from each other; and a production method therefor. [Solution] When Δb refers to the difference between value b1, which is the b value of a roughened surface portion 3, and value b2, which is the b value of a second surface 7, this medical sheet has a Δb in the range of 1.5-11 inclusive. A production method for the medical sheet includes: a surface roughening step in which a portion or the entirety of a first surface 5 of a sheet including polytetrafluoroethylene is subjected to surface roughening treatment to form a roughened surface portion 5; and a heating step in which the sheet which includes the polytetrafluoroethylene and which has undergone the surface roughening step is heated to obtain the medical sheet.
(FR) [Problème] Le problème décrit par la présente invention est de fournir : une feuille médicale avec laquelle une surface (une partie) soumise à un bombardement ionique, et une surface (une partie) qui n'a pas été soumise à un bombardement ionique peuvent être distinguées l’une de l’autre; et un procédé de production associé. [Solution] lorsque Δb se réfère à la différence entre la valeur b1, qui est la valeur b d'une partie de surface rugueuse 3, et une valeur b2, qui est la valeur b d'une seconde surface 7, cette feuille médicale a un Δb dans la plage de 1,5 à 11 inclus. Un procédé de production de la feuille médicale comprend : une étape de rugosification de surface dans laquelle une partie ou la totalité d'une première surface 5 d'une feuille comprenant du polytétrafluoroéthylène est soumise à un traitement de rugosification de surface pour former une partie de surface 5 rugueuse; et une étape de chauffage dans laquelle la feuille qui comprend le polytétrafluoroéthylène et qui a subi l'étape de rugosification de surface est chauffée pour obtenir la feuille médicale.
(JA) 【解決課題】 イオン衝撃が施された面(部分)と,イオン衝撃が施されていな面(部分)とを区別できる医療用シート及びその製造方法を提供する 【解決手段】 粗面化部3のb値であるb1値と,第2の面7のb値であるb2値の差をΔbとしたときに,Δbが1.5以上11以下である医療用シート及びポリテトラフルオロエチレンを含むシートの第1の面5の全部又は一部を粗面化処理し粗面化部5を形成する粗面化工程と,粗面化工程を経たポリテトラフルオロエチレンを含むシートを加熱し,医療用シートを得る加熱工程と,を含む医療用シートの製造方法。
