A medical wetness sensing device includes a base adapted to be disposed on a wearer of the medical wetness sensing device. The base includes a first electrical conductor and a second electrical conductor electrically insulated from the first electrical conductor. The first electrical conductor includes a hinge portion enabling a first portion of the first electrical conductor to deflect, at the hinge portion, relative to a second portion of the first electrical conductor. The medical wetness sensing device includes a controller electrically connected to the first electrical conductor and the second electrical conductor. The controller is configured to detect a presence or an absence of a medical fluid electrically connecting the first and second electrical conductors.

A wearable device for at least one of icing, heating and compressing a user’s body part is disclosed. The wearable device comprises an inner part and an outer part. The outer part is arranged with the inner part such that the outer part surrounds the inner part. A compartment is defined by the space between the outer part and the inner part and above the first attaching means. A compression force is provided by the second set of elastic properties compressing at least one of the hot element and the cold element against the user’s body part thereby eliminating a second attaching means above the first attaching means within the compartment. At least one handle is in attachment with the outer part. The wearable device further comprises at least one band disposed on the outer part between the outer part upper end and outer part lower end.

A medical bandaging and tourniquet system for use in dressing puncture wounds is provided. The medical bandaging and tourniquet system includes a primary dressing, a secondary dressing, a band, a tightening buckle, a retaining clip, and a tightening rod. The primary dressing serves as a main wrapping bandage that mounts the secondary dressing and tourniquet components together. The secondary dressing removably attaches to the primary dressing and serves as a bandage that can be installed onto minor wounds. The band connects to the primary dressing, serving as an elastic tourniquet band. The tightening buckle and the retaining clip are connected to the primary dressing. The tightening rod is positioned between the tightening buckle and the retaining clip. The primary dressing straps tightly along a wound though the tightening buckle. The strap is further compressed by turning the tightening rod. The tightening rod can then be secured to the retaining clip.

A method of promoting hemostasis in the mouth or oral cavity utilizes a non-absorbent, low surface energy and highly conformable non-disruptive hemostasis material. Traditional wound packing material is highly absorbent and has large open surfaces that allow clot forming materials, such as the platelet plug to adhere to the packing material and whereupon removal, the clot is disrupted. A non-disruptive highly conformable hemostasis material does not have large open pores and therefore does not adhere to forming clots. A non-disruptive hemostasis material may consist of expanded polytetrafluoroethylene that has a pore size of no more than about 10 microns. A non-disruptive hemostasis material may comprise a thin film of material over a portion of the outside surface that is non-absorbent and thin to allow for conforming into an oral cavity, such as from a tooth extraction. A thin film may cover porous material, such as a foam, that may be elastomeric.

The present disclosure relates to apparatus for covering a burn or other wound in ways that prevent or limit touching the wound. The present disclosure describes Burn Bandages that may include domes or structures that bridge over a wide range of a burn or wound size. In certain instances these structures may expand in one or more directions as they are adjusted to fit to a particular burn or wound size. Such bridging structures may include airways, openings, or voids that promote air/oxygen flow to the wound as the Burn Bandage sits upon surfaces or pads that contact healthy surrounding tissue while they cover a wound site. The apparatus may be any shape including, yet not limited to, a circle, a rectangle, a square, a hexagon, an octagon, an oval, a cone, a cylinder, have a semi-cylindrical shape, or that have any another geometric shape.

A wound dressing is disclosed that includes a water resistant visual indicia provided on an area of the dressing. The water resistant visual indicia may be provided on a tag attached to the dressing. The tag may comprise a top sheet and a bottom sheet, the bottom sheet comprising a writeable surface on which the visual indicia is handwritten, or printed.

The present disclosure relates to a collagen-alginate wound dressing, including a matrix in which a low-molecularized collagen and a low-molecularized alginate are crosslinked and a method of preparing the same.

Disclosed herein are systems and methods for safe operation of a wound treatment apparatus with electronic components integrated on or within a wound dressing. In some embodiments, the electronic components include a power source, an isolation circuit, a controller, a capacitor, and a negative pressure source. The isolation circuit provides multiple activation states with at least one state preventing application of power to the other electronic components capable of storing electrical energy, thereby providing a safe operation of the apparatus. For example, sterilization of the apparatus can be performed safely.

An orthopedic system configured for use in a pre-operative, intra-operative, and post-operative assessment. The orthopedic system comprises a first screw, a second screw, a first device, a second device, and a computer. The first device and the second device are respectively coupled to a first bone and a second bone of a musculoskeletal system. The first and second devices each include electronic circuitry, one or more sensors, and an IMU. A bracket, wrap, or sleeve can be used to hold the first and second devices to the musculoskeletal system. The first and second devices are configured to send measurement data to a computer. The first and second devices each have an antenna system. Electronic circuitry in the first or second devices are configured to harvest energy from a received radio frequency signal to recharge a battery to maintain operation.

The inventors have discovered hot melt adhesive compositions that can be formulated to have a high percentage of environmentally conscious components and still provide performance over a broad temperature range.

The invention features a hot melt adhesive composition including from 5% by weight to 50% by weight of a styrene block copolymer, from 15% by weight to 75% by weight of a bio-based tackifying agent, and from 5% by weight to 40% by weight of an aliphatic plasticizer having a cyclo-aliphatic content of no greater than 1% by weight as tested by .sup.1H-NMR Spectroscopy, wherein said hot melt adhesive composition has an environmentally conscious component content of at least 50% by weight.
