Abstract
An envelope is comprised of two sheets of material that are placed one on top of each other with their interior sides facing each other with their edges sealed to each other with an adhesive to form an airtight enclosure. The envelope has at least one medical patch inside it that is attached to the interior side of at least one of the sheets and a layer of medical grade pressure sensitive adhesive surrounding the at least one medical patch. The pressure sensitive adhesive is applied to a part of the surface of the interior side of the sheet in order to attach the sheet of material and the at least one medical patch to the body of a patient. The medical patch can be an electrode for measuring a patient's vital signs or delivering an electric shock or a transdermal patch for delivering a drug to a patient.
Core Innovation
The invention relates to an airtight medical patch envelope for rapid application of pre-attached medical patches. The envelope is formed as either one sheet folded into two parts along a fold line with remaining edges sealed with an adhesive, or two sheets placed with interior sides facing each other and their edges sealed with an adhesive to form an airtight envelope. At least one medical patch is attached to the interior side of each of the two parts or two sheets, and a surrounding medical-grade pressure-sensitive adhesive layer is applied to a part of the surface of the interior side surrounding each medical patch.
Each medical patch and the areas covered by the layer of adhesive surrounding each medical patch do not overlap each other when the two parts or two sheets are assembled to form the envelope. When the envelope is opened by pulling apart the sealed edges and separating the two parts or two sheets, the layer of adhesive surrounding each medical patch is configured to hold the two parts or two sheets and the attached medical patches to a body of a patient when the interior sides are pressed onto the body.
The envelope is designed to support electrode patches and transdermal drug patches sealed inside the envelope. Embodiments include electrode patches with pre-connected electrical contacts and electrical leads, including gel-covered electrodes and optional electrode arrays for ECG/EEG/defibrillation and research electrodes.
Claims Coverage
The provided claims present one independent claim with two main inventive features, together with dependent refinements for patch types, electrical connections, liners, and medication-control aspects.
Airtight envelope for pre-attached medical patches
An envelope comprised of either one sheet folded into two parts along a fold line with remaining edges sealed with an adhesive, or two sheets placed with interior sides facing each other and edges sealed with an adhesive to form an airtight envelope; at least one medical patch is attached to the interior side of each of the two parts or two sheets, and a layer of adhesive is applied surrounding each medical patch, with the patch and surrounding adhesive areas not overlapping when assembled and configured to hold the patches to a patient body when opened and pressed.
The claim coverage centers on the airtight envelope architecture and the non-overlapping interior adhesive arrangement that enables the pre-attached medical patches to be held to a patient upon opening and application. Dependent refinements include electrical contacts and leads, patch types, non-stick liners, printed placement instructions, different electrode sizes and spacing, and medication-release control.
Stated Advantages
Enables easy separation of the two parts or two sheets without tearing, while keeping the at least one medical patch sterile and keeping the medical-grade adhesive layer fresh.
Configures the layer of adhesive so it holds the attached medical patches to a body of a patient when the interior sides are pressed onto the body upon opening the envelope.
Documented Applications
Electrode patches for medical purposes and biomedical research, including gel-covered electrodes and optional electrode arrays for ECG/EEG/defibrillation and research electrodes.
Transdermal drug patches sealed inside the envelope, with embodiments where medication release is controlled.
