Aspects of the present disclosure relate to a warming system. The warming system includes a light device having a light source configured to be positioned proximate to a patient support having a patient support surface. The light source can also be configured to generate infrared radiation. The warming system can also include a flexible sheet having a first side configured to reflect at least some of the generated infrared radiation from the light device toward a portion of the patient support surface.

Radiative warming system

Shapeable articles, kits including one or more of the shapeable articles, and methods of making and/or using the shapeable articles. The shapeable articles include a shapeable member that can be shaped or manipulated into three-dimensional shapes without the use of tools and hold those shapes after removal of the force required to achieve the shape. The shapeable articles could have a variety of uses including use as surgical retractors to move and/or restrain non-target tissue and/or organs to improve access to the target tissue and/or organs.

Shapeable articles and methods of making and using the same

Durable hydrophilic compositions comprising aliphatic polyester, an anionic surfactant, and in some embodiments, a carrier.

Biocompatible hydrophilic compositions

Multilayer articles having an absorbent nonwoven layer and a barrier layer are described, including those having a surfactant-treated, aliphatic polyester, nonwoven absorbent layer and a barrier layer. Multilayer articles including a tie layer used to enhance the bond between the hydrophilic absorbent layer and the barrier layer are also described. Methods of making and using such articles are also described.

Multi-layer articles

Dimensionally stable nonwoven fibrous webs include a plurality of fibers formed from one or more thermoplastic polyesters and an antishrink additive, preferably in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 12% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. The webs may be used as wipes.

Dimensionally stable nonwoven fibrous webs, and methods of making and using the same

Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. When the thermoplastic polyester is selected to include aliphatic and aromatic polyesters, a spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. When the thermoplastic polyester is selected from aliphatic polyesters, a meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing.
