VISCOELASTIC MEDICAL ARTICLE

摘要

A medical article and methods of using same. The medical article can include a machine direction (MD) and a cross-machine direction (CMD); a support layer; and a viscoelastic layer. The viscoelastic layer can be coupled to the support layer, and the viscoelastic layer can be discontinuous in the MD and/or the CMD. The viscoelastic layer can recover at least 70% of its deformation after 48 hours at room temperature after being strained to 50% elongation, such that the medical article has a first tensile stiffness T1 at a first strain rate S1, and a second tensile stiffness T1 at a second strain rate Si. The ratio of S1/S2 can be at least 100, and the ratio of T1/T2 can be at least 1.5. The method can include wrapping the medical article around a body part; applying the first strain rate S1; and applying the second strain rate S2.

1. A medical article comprising:
a machine direction (MD) and a cross-machine direction (CMD); a support layer; a viscoelastic layer coupled to the support layer, wherein the viscoelastic layer is discontinuous in at least one of the MD and the CMD, wherein the viscoelastic layer recovers, in at least one of the MD and the CMD, at least 70% of its deformation after 48 hours at room temperature after being strained to 50% elongation, such that the medical article has, at room temperature, in at least one of the MD and the CMD, a first tensile stiffness Ti at a first strain rate Si applied in the at least one of the MD and the CMD and a second tensile stiffness Ta at a second strain rate Sz applied in the at least one of the MD and the CMD, wherein the ratio of S1/S2 is at least 100, and wherein the ratio of T1/T2 is at least 1.5.
