An adhesive article including a tie layer and a silicone adhesive is disclosed. The tie layer includes a segmented copolymer having a first segment that is one of (a) a polyether comprising one of PTMO or PEO/PPO or (b) a polysiloxane. The segmented copolymer has a water absorbency of less than about 13%.

Tie layer chemistry to promote bonding with silicone adhesive

Articles are provided that include a fibrous substrate and porous polymeric particles. At least 50% of the porous polymeric particles are bound to the fibrous substrate. Methods of making the articles are provided that include providing porous polymeric particles, providing a fibrous substrate, and binding the porous polymeric particles to the fibrous substrate. The articles can be used for fluid management.

The disclosed medical dressing has a dressing body and a flap. The dressing body has a first major surface and opposite second major surface containing a skin-contact adhesive. The flap has a fixed end integrally connected to the dressing body and a movable free end. The second major surface of the flap has a securing adhesive for contact with the first major surface of the dressing body.

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.

A securement device for securing a medical article is disclosed. The securement device comprises a base and a first securing portion comprising a strap that is movable between an open position and a closed position and a connector disposed on the base. The strap cooperates with the connector in the closed position to form an enclosure. The strap further comprises a curvilinear segment that projects inwardly into the enclosure in a convex orientation when the strap is in the closed position. Securement systems for securing medical articles and methods of securing at least a portion of a medical article to a patient are also provided.

Catheter securement device

A medical dressing () with a dressing body () and a flap (). The flap can include a fixed end () coupled to the dressing body, and a free end () movable with respect to the dressing body between a first position and a second position in which the free end is positioned in overlapping relationship with the dressing body. A second major surface () of at least the free end of the flap can be configured to be secured to the dressing body, and the flap can be located toward a proximal end of the dressing body, such that a distal portion of the dressing body is free of the flap. The dressing body can be adhered to skin with a skin-contact adhesive (e.g., a silicone adhesive) (), and the flap can be secured to the dressing body with a securing adhesive (e.g. an acrylate adhesive) () that can have a higher adhesion or adhesive strength.

Medical dressings and methods of using same. The medical dressing can include a fluid management article. The fluid management article can include a fibrous substrate and porous polymeric particles. At least 50% of the porous polymeric particles are bound to the fibrous substrate. Methods of using the medical dressings can include applying the medical dressing to the target site, such that the fluid management article is in fluid communication with the target site.
