    Abstract: The disclosed securement device for medical tubing has a polymeric film and adhesive. The polymer film has a first major surface, a second major surface opposite the first major surface, a first flat portion, a second flat portion, a formed bend between the first flat portion and second flat portion, the bend defining a channel, and a notch formed through the polymer film adjacent the bend and between the first flat portion and second flat portion, such that the notch is aligned with the channel. Then adhesive is on at least a portion of the second major surface of the polymer film.

    Abstract: A viscoelastic wound closure dressing. The dressing can include a viscoelastic backing having a first major surface configured to face skin when in use, a first end, a second end, and a middle section located between the first end and the second end. The wound closure dressing can further include a skin-contact adhesive on the first major surface of the viscoelastic backing adjacent the first end and the second end. A majority of the first major surface of the middle section can be free of the skin-contact adhesive. The viscoelastic backing can recover, at room temperature: (i) no more than 40% of its deformation after 10 seconds, after being strained to 50% elongation for 30 minutes, and (ii) at least 70% of its deformation after 48 hours, after being strained to 50% elongation for 30 minutes.

    Abstract: 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.

    Abstract translation: 医疗用品及其使用方法。 医疗用品可以包括机器方向（MD）和跨机器方向（CMD）; 支撑层; 和粘弹性层。 粘弹性层可以连接到支撑层，并且粘弹性层可以在MD和/或CMD中不连续。 粘弹性层在应变到50％伸长率后，可以在室温下48小时后恢复至少70％的变形，使得医用制品在第一应变速率S1具有第一拉伸刚度T1，第二拉伸刚度T1 在第二应变率Si下。 S1 / S2的比例可以至少为100，T1 / T2的比可以至少为1.5。 该方法可以包括将医疗制品包裹在身体部位周围; 施加第一应变率S1; 并施加第二应变率S2。
