International Classification:

A44C 5/00

US Classification:

40633, 40661

Abstract:

A recipient verification system including a band and a label strip. The band includes a base, a trailing shield segment, and a strap. The band defines a band identification portion displaying a band identifier, as well as opposing passages. The trailing shield segment is disposed over the identification portion. The strap extends from the base and terminates at a tail end. The label strip extends from the base and includes at least one removable label displaying the predetermined band identifier. In an initial state, the strap is free of the band identification portion. In the worn state, the strap is wrapped about a wearer's appendage, with the tail end passing through at least one of the passages and a section of the strap maintained along the identification portion. The predetermined band identifier displayed on the identification portion is visible through the trailing shield segment in the worn state.

Abstract:

A polymer blend comprising a high density polyethylene and a surface enhancing polymer is provided. The surface enhancing polymer may be an elastomer such as an ethylene propylene diene monomer terpolymer. The polymer blend may be fabricated into articles such as a film or a flexible overpouch for storing, and transporting medical components. Overpouch films made from the blend advantageously do not wrinkle or deform medical components contained therein when the overpouch—medical component combination is autoclaved.

International Classification:

A44C 5/00

US Classification:

40633, 283 70

Abstract:

A recipient verification system including a strap, a pocket, a tether, and a label strip. The strap is configured for placement about a wearer's appendage (e. g. , wrist, ankle, etc. ). The pocket is coupled to the strap and forms an interior region that is exteriorly accessible via an open end. A portion of the tether is permanently captured at the pocket. The label strip is attached to the tether. The tether and the attached label strip are repeatedly transitionable between a first state and a second state. In the first state, the tether and at least a majority of the label strip is within the pocket, and thus protected. In the second state, at least a majority of the label strip is outside of the interior region of the pocket, and available for use by a user.

International Classification:

A61F007/00

US Classification:

607114000

Abstract:

The invention described herein provides an improved thermal device having enhanced storage longevity and chemical integrity. The thermal device comprises a flexible plastic containment and activatable thermochemical liquid composition contained therein. The flexible plastic containment is constructed using a multilayer film comprising an outer polymeric barrier layer comprising an oxide coating, and an inner polymeric sealant layer. The thermal device inhibits or prevents water loss through the film, thereby enhancing the chemical integrity of the thermochemical composition within.

US Classification:

40633, 156277

Abstract:

A recipient verification system including a band to be worn by a patient or other recipient that allows for placement of a hospital's own identification label, which is then protected from damage, an area for a permanent label, which can then be associated with the hospital label, a series of removable labels that remain with the patient, a test tube label, and a tail of labels to be removed from the band at the time of application to the patient to ensure a sufficient supply of labels. Each of the permanent label, the removable labels, the test tube label, and the tail are encoded with identical identification information. The band and label strip are separately formed from desired materials and then assembled.

International Classification:

G09F 3/00

US Classification:

40633

Abstract:

A recipient verification system including a band having a base, a strap, and a closure device. The base defines a band identification portion for displaying a recipient identifier. The strap extends from the base, and the closure device is attached to the base opposite the strap. First and second slots are formed through the band. In a primary worn state, the strap is looped about a recipient's appendage and secured to the base via the closure device independent of the slots. In a replacement worn state, the base is severed from a majority of the strap and is secured to the recipient's appendage by a secondary band assembled through the slots.
