According to the disclosure, the motor device (52) comprises a driving mean (56) and the cylindrical drum (18) comprises the corresponding driven mean (50) arranged at the periphery of one of the longitudinal ends (49,60) of the cylindrical drum (18), the driving mean (56) actuating the driven mean and cylindrical drum (18).

A dressing for wound healing is provided herein including dehydrated placental tissue, collagen, and oxidized regenerated cellulose. The dehydrated placental tissue may be present in a first layer and the collagen and the oxidized regenerated cellulose may be combined into a second layer. The dehydrated placental tissue may comprise amniotic membrane tissue, chorion tissue, or a combination thereof. The second layer including the collagen and the oxidized regenerated cellulose may comprise about 50% to about 60% collagen by weight and about 40% to about 50% ORC by weight.

Wound dressing assembly including (i) blood-clotting mold device having an enclosure defined between walls of a main body and a removable closure over an opening and configured for introduction of blood thereinto, and (ii) coagulation initiator in amount sufficient to coagulate blood introduced into the enclosure to form a blood clot. The formed blood clot is transferable onto a wound. Method for preparing a wound dressing by introducing a volume of blood into the enclosure of the blood-clotting mold device, maintaining the blood within the enclosure for time sufficient to permit clotting of the blood to obtain a blood clot; removing said the closure to open the enclosure; and extracting the blood clot from the enclosure. The formed blood clot may be used in a method for dressing a wound by fixation of the clot onto the wound.

A dressing for treating tissue with negative pressure may be a composite of dressing layers, including a release film, perforated gel layer, a perforated polymer film, a manifold, and an adhesive cover. A method of manufacturing the dressing may comprise providing a first layer, such as the gel layer, on a substrate, perforating the first layer on the substrate to create a plurality of apertures in the first layer, and creating an index of the plurality of apertures in the first layer. A laser can be calibrated based on the index. A second layer, such as the polymer film, may be coupled to the first layer, and a plurality of slots can be cut in the second layer with the laser. Each of the slots can be cut through one of the apertures in the first layer based on the index.

Continuous edge folds of a top sheet in disposable products prepare the top sheet for placement/attachment of discrete side panels to the folded-over portion of top-sheets oriented so that the side panels lay on top of the top-sheet without any further folding steps required. Later, a back sheet can be added and back sheet edges then folded over to cover edges of top-sheet/side panel sandwich.

Computer-implemented method for determining a tension value of a limb (5) of a person, the tension value of the limb (5) being used along with a skin value of the limb (5) for production of a custom-tailored compression garment for the limb (5), the skin value describing the circumference of the limb (5) without any applied compression and the tension value describing the circumference of the limb (5) with the compression garment applying a desired compression, wherein the skin value of the limb (5) is received and the tension value of the limb (5) is calculated from the skin value according to a calculation instruction parametrized by at least one parameter, the parameter being derived from a dataset (11) comprising multiple associated tuples of skin values and tension values.

Dressings, systems, and methods are disclosed, in some embodiments, that involve treating a tissue site with reduced pressure. In one embodiment, a reduced-pressure dressing may include a dressing bolster, a retention pouch, and a sealing member. The dressing bolster may be adapted to apply a compressive force to the tissue site capable of closing a wound or incision therein. The retention pouch may be adapted to retain and manage fluid extracted from the tissue site to keep the tissue site substantially free of fluid and to prevent clogging of the reduced-pressure dressing. The sealing member may provide a seal over the retention pouch, the dressing bolster, and a portion of the epidermis of the patient. Other dressings, systems, and methods are disclosed.

A wound dressing includes at least one sensor generating a sensor signal. The wound dressing also includes a display configured to receive the sensor signal from the at least one sensor and present data corresponding to the sensor signal.

Disclosures of the present invention describe a double-layer dressing containing silk fibroin and a method for making the same. The double-layer dressing mainly comprises a silk fibroin layer and a calcium-degradation silk fibroin layer connected to the silk fibroin layer. It is worth emphasizing that, results of animal experiment have proved that this novel double-layer dressing is an outstanding hemostatic wound dressing. Moreover, additional adhesion, resulted from the solidification of tissue fluid, can be effectively prevented from forming between skin wound and wound dressing under the use of this double-layer dressing.
