Abstract: A method of manufacturing a laminated dressing that includes providing a lower layer having a fiber material that directly contacts a patient's skin and a wound area, providing an upper layer that has a foam or foam-like material that absorbs exudate and moisture, and binding the fiber-based lower layer and the foam-based upper layer with a binder layer comprising a binder material, the binder layer including a series of perforations. The perforations in the binder layer are formed by removing material from the binder layer with a pattern coated adhesive sheet prior to binding the fiber-based lower layer and the foam-based upper layer.

Abstract: Certain embodiments relate to a soft odor barrier material in a medical device. The soft odor barrier material includes an elastomer and an antiblocking agent. In certain forms, the antiblocking agent imparts an interior rough surface having an arithmetic mean surface roughness (Ra) not less than 0.1 μm. In certain forms, the antiblocking agent is non-blocking upon folding and packaging.

Abstract: An integrated system for assessing wound exudates from the wound of a patient is described. The system may contain functionality to detect, process and report various wound parameters. The system also may make treatment determinations based on these findings. The system may detect one or more physiological values of the wound exudates from the wound of the patient. The system may means for comparing the one or more detected physiological values to predetermined physiological values in order to obtain a comparison result in real time. The system may include a processor 15 which provides an electronic signal based on a comparison result in which the electronic signal may correspond to guidelines for treating the wound 13. The system may be integrated with other wound treatment devices, such as negative pressure wound therapy devices (NPWT) 9.

Abstract: An apparatus (10) for controlling flow of fluid from a wound site of a patient may include a chamber (28) connectable to a wound site and a reservoir (16). The chamber (28) may have a first deformed state, and a second state in which it is not deformed or less deformed than in the first state. The chamber (28) may be adapted to manage fluid flow between the wound site and the reservoir (16) during transition of the chamber (28) between the first state and the second state. An actuator element (64) of the apparatus (10) may be adapted to operate on the chamber (28) to transition the chamber (28) from the second state to the first state.

Abstract: The end of the elongated tubular element of the appliance that is designed to be inserted into a body cavity is formed entirely of soft, compliant material. That end carries an inflatable balloon made of non-expandable material, formed in the fully inflated shape, to prevent overexpansion. The balloon is inflated to a predetermined low pressure level to prevent pressure necrosis in the adjacent tissue. A method and apparatus for introducing the soft end of the appliance into the body cavity are also provided. The introducer apparatus includes rigid core surrounded by a soft, compliant sleeve. The sleeve extends beyond the rigid core to form an invertable section. The soft end of the appliance is situated adjacent the apparatus, the balloon is wrapped around the apparatus, and the sleeve section is inverted over the appliance, compressing the balloon and forming a soft, rounded insertion tip. The unit is then introduced into the body cavity. After the appliance is separated from the apparatus, the apparatus is withdrawn.

Abstract: A method of diagnosis or prediction of infection of a mammalian wound, said method comprising the step of detecting the presence of a cytokine selected from the group comprising procalcitonin, amino procalcitonin (N-ProCT), eotaxin, granulocyte macrophage colony stimulating factor (GM-CSF), interleukins IB monocyte chemotactic protein-1 (MCP-1), macrophage inflammatory protein-1 alpha (MIP-1a), regulated upon activation normal T expressed and secreted (RANTES) in fluid taken from the wound. Also claimed is the device for use in the method.

Abstract: A stand-alone system for assessing wound exudates from the wound of a patient is described. The system contains functionality to detect, process and report various wound parameters. The system also may make treatment determinations based on these findings. The system may detect one or more physiological values of the wound exudates from the wound of the patient. The system may also compare detected physiological values to predetermined physiological values, in order to obtain a comparison result in real time. The system may include a processor (15) which provides an electronic signal based on the comparison result in which the electronic signal may corresponds to guidelines for treating the wound (3). The system described may be an accessory, which may be used on its own, or in conjunction with other wound treatment devices (9).
