This disclosure relates to swellable needles that include a proximal end portion and a swellable distal end portion. Upon exposure to a liquid, the needles are configured to undergo a shape change from a first configuration in which the width of the needle is tapered from the proximal end portion to the distal end portion to a second configuration in which the distal end portion is more swollen than the proximal end portion. The swellable needles can be double layer swellable needles or single material swellable needles.

Devices, systems, and methods used to seal and secure a medical device at an insertion site are disclosed. The systems include a mating dressing device, a central connector, and a compression lock collar. The mating dressing device includes an adhesive plate portion that forms a first circumferential seal around the insertion site and a mating body portion that the central connector form fits to. The compression lock collar compresses the mating body portion against the central connector to form a second circumferential seal. The systems can also include a segment of intravenous tubing coupled to the central connector and used for application of the mating dressing device and compression lock collar.

Provided herein is an intravascular catheter assembly, including a catheter adapter having a distal end, a proximal end, a lumen arranged between and in fluid communication with the distal end and the proximal end, a catheter arranged at the distal end of the catheter adapter and in fluid communication with the lumen, and a side port in fluid communication with the lumen. The assembly further includes a fluid conduit having a distal end and a proximal end, the distal end of the fluid conduit coupled to the side port, a connector arranged at the proximal end of the fluid conduit, and an occlusion device configured to stop flow through the fluid conduit.

A closed-circuit dressing system for preventing moisture contacting PICC sites is provided. The closed-circuit dressing system include a breathable bag for harboring the PICC line(s) and a dressing film that envelopes the PICC site, wherein a moisture indicator ring provided by the dressing film indicates moisture penetrating a dressing reinforcement along the periphery of the dressing film.

A transparent dressing includes a portion without adhesive to allow placement over a catheter to reduce any effect of placing and positioning of a catheter at the time of removal of the dressing. The transparent dressing may include at least one tab for handling and removing the dressing, the at least one tab being positioned on at least one outer edge of the dressing.

Occlusive tissue dressings and methods including an elastomeric drape and a liquid component, at least partially cross-linked at least after one of drying and curing, suitable for application at a dressing-to-skin interface in order to create a substantially air-tight seal. The same or a different liquid component may be applied by a user at a tube-to-dressing interface in order to create a similar air-tight seal around the tube, if not occlusively sealed during its manufacture.

A pressure-reducing dressing is adapted for securing medical equipment to the skin of a human body, and includes a skin contact pad adapted for locating the medical equipment, a water barrier laminate positioned on the skin contact pad, and a release sheet. The water barrier laminate includes a body layer and an adhesive layer formed on a side surface of the body layer that faces the skin contact pad and adhered to the skin. The body layer has a positioning portion and two divisional portions extending from the positioning portion and spaced apart from each other by a separating gap. The release sheet is attached to the adhesive layer of the water barrier laminate.

The disclosed medical dressing includes a dressing body with an overlying carrier system that is releasably secured to the dressing body. The carrier has a perimeter carrier portion overlying the perimeter of the dressing body and a central carrier portion overlying some, but not all, of a central area of the dressing body. This carrier construction allows for better handling of the medical dressing during application by giving both stability in some areas and stretching and flexibly in areas without the carrier.

The present invention provides a protective device that protects the patient's skin and underlying tissue from pressure and injury resulting from pressure on the skin/tissue and/or compression of nerves by IV lines associated with medical procedures, medication administration, for nutritional purposes, and the like. In one embodiment, a protective device in accordance with the present invention comprises a body defining a window dimensioned to receive a portion of an IV line, said body having a lower surface having an area greater than said portion of said IV line. The window may be internal to, or open to, a peripheral edge of the body. Adhesive may be applied to the upper and/or lower surface of the body. A securing tab or catch may be provided to secure the IV line to the body.

Disclosed herein is a device which is intended to deliver and maintain reduced pressure to body surfaces for application of reduced pressure wound therapy (RPWT) also known as negative pressure wound therapy (NPWT). During application of this type of therapy, a substantially airtight seal is formed around a section of tissue to be treated. This seal is formed by a dressing which provides fluid communication from a section of tissue to a reduced pressure source. Disclosed herein is a dressing system which is configured to enhance usability and functionality of this dressing. First, the system may be configured to allow full rotation of the fluid communication conduit to the reduced pressure source along the axis substantially normal to the dressing. Second, the system may be configured to include a one-way valve to prevent backflow of any drainage fluids. Third, the system may be configured with transparent windows covered by opaque flaps to allow inspection through the dressing. Fourth, the system may be configured to include an indicator which visually makes clear whether reduced pressure is being applied or not. Fifth, the system is configured to minimize the profile of the dressing system.
