Dressing with fluid acquisition and distribution characteristics
Systems, methods, and apparatuses for treating a tissue site are described, In some embodiments, the system may include a pouch having an upstream layer, a downstream layer, and an absorbent member enclosed between the upstream layer and the downstream layer. The upstream layer and the downstream layer may each include a hydrophobic side and a hydrophilic side, The hydrophilic side of both the upstream layer and the downstream layer may be positioned facing the absorbent member. The hydrophobic side of both the upstream layer and the downstream layer may form a portion of an exterior surface of the pouch such that fluid incident on the pouch is distributed laterally along the exterior surface of the pouch before being absorbed by the absorbent member.
Reduced-Pressure, Linear-Wound Treatment Systems
A system for treating a linear wound on a patient has a closing dressing bolster for placing on the patient's epidermis over the linear wound, a sealing subsystem for providing a seal over the closing dressing bolster and the patient, and a reduced-pressure subsystem for delivering reduced pressure to the sealing subsystem. The sealing subsystem and reduced pressure subsystem are operable to deliver reduced pressure to the closing dressing bolster. The closing dressing bolster is operable under reduced pressure to develop a inward closing. The closing dressing bolster may include one or more closing members on each side of a center wound area to create the inward closing when under reduced pressure. A compressive force may also be developed. Other systems and methods are presented.
SOLID DRESSING FOR TREATING WOUNDED TISSUE AND PROCESSES FOR MIXING FIBRINOGEN AND THROMBIN WHILE PRESERVING FIBRIN-FORMING ABILITY, COMPOSITIONS PRODUCED BY THESE PROCESSES, AND THE USE THEREOF
Fibrin Sealant products are used for topical hemostasis and tissue adherence. They are composed of two main reagents, fibrinogen and thrombin. When mixed in solution fibrinogen is converted to fibrin upon the addition of activated thrombin. Therefore typically these two components are stored separately in a lyophilized or liquid state, and mixed, upon or immediately before, application to a patient. While effective, these products require significant preparation that must take place immediately before application, thus delaying treatment and limiting the use of these haemostatic products to the treatment of mild forms of low pressure and low volume bleeding. Attempts to eliminate this delay and expand the usefulness and effectiveness of these products have resulted in products produced by processes that require the separation of these components and their deposition in distinct layers within the product. The processes described herein permit the mixing of fibrinogen and thrombin during product manufacture, without excessive fibrin formation. The resulting pre-mixed fibrin sealant material can then be stored in either a frozen or dried state, or suspended in a non-aqueous environment. Activation of the material to form therapeutic fibrin sealant is accomplished by permitting the product to thaw (if frozen) or by the addition of water or other aqueous fluid, including blood, or other bodily fluids, if dried or suspended in a non-aqueous environment. The resulting material can be used to make a product in which a pre-mixed form of activatable fibrin sealant is a desired component.
ENERGY GENERATION FROM FABRIC ELECTROCHEMISTRY
Disclosed and described herein are systems and methods energy generation from fabric electrochemistry. An electrical cell is created when electrodes (cathodes and anodes) are printed on or otherwise embedded into fabrics to generate DC power when moistened by a conductive bodily liquid such as sweat, wound, fluid, etc. The latter acts, in turn, as the cell's electrolyte. A singular piece of fabric can be configured into multiple cells by dividing regions of the fabric with hydrophobic barriers and having at least one anode-cathode set in each region. Flexible inter-connections between the cells can be used to scale the generated power, per the application requirements.
COMPOSITIONS HAVING CYLINDRICAL VOLUME, METHODS, AND APPLICATORS FOR SEALING INJURIES
Disclosed are solid and frozen haemostatic materials having a rod shape and suitable applicators and plungers for application of such dressings to wounded tissue wherein said dressings consisting essentially of a fibrinogen component and a fibrinogen activator. Also disclosed are methods of treating internal wounded tissue in a mammal by applying one or more of these haemostatic materials and dressings, particularly for the treatment of injured tissue via endoscopic or minimally-invasive surgical techniques.
Method and system for providing active tissue site debridement
A wound debridement system includes a wound dressing having an active layer and a wound interface layer. The active layer is formed from one or more transmission layers that are arranged about a central post. Activation of the transmission layers is configured to cause the movement of the wound interface layer relative to a tissue site to which the wound dressing is applied. A drive unit is operably attached to the central post. The drive unit is configured to generate and transfer a vibrational energy and/or a rotational movement to the transmission layer(s) via the central post. The resultant vibration and/or rotation of the transmission layer(s) is imparted onto the wound interface layer, thereby effectuating the desired movement of the wound interface layer relative to the tissue site, which allows for the debridement of debris that may be located at the tissue site.
Magnetic dressing and preparation method and use thereof
The present disclosure provides a magnetic dressing and a preparation method and use thereof, belonging to the technical field of pharmaceutical preparations. The magnetic dressing includes a magnetic layer, a drug-loading layer, and a protective layer that are stacked in sequence, where the magnetic layer includes polyvinyl alcohol, gluten, and iron particles. In the present disclosure, a swallowed magnetic dressing is controlled by an external magnetic field, and the magnetic dressing is moved to a pathological position by changing a direction of the external magnetic field; after the external magnetic field is removed, the magnetic dressing changes from a ring to a sheet, thereby completing attachment of an entire lesion surface to complete treatment by autonomous drug release.
Vented wound dressing barrier
A vented wound dressing barrier includes one or more membrane layers with a plurality of vents. The vents are cut along a perimeter of the vents through the one or more membrane layers. Each vent having a connection portion uncut relative to the one or more membrane layers thereby forming a hinge configured to allow the vents to open for drainage when exposed to fluid underlying the vented wound dressing barrier. The plurality of vents is each cut along the perimeter without removal of any of the membrane layer. The one or more membrane layers with the plurality of vents has a surface for covering a wound, the surface area in the absence of a fluid pressing on the vents having no openings or voids which reduce the surface area of a vented wound dressing barrier area covering a wound.
Negative Pressure Therapy Systems and Sponges
Negative pressure wound therapy sponges that are custom-fabricated to fit a given wound to be treated, corresponding methods of creating said sponges in situ or external to a wound, and related systems for performing negative pressure wound therapy using said sponges. Exemplary sponge embodiments may have pressure-sensing capabilities.
APPARATUS
An apparatus that includes a mask is provided, the mask including one or more fixation anchoring devices, each configured to anchor to an at least one body part within a user, wherein the at least one body part includes at least a portion of one or more of an oral, nasal, pharyngeal, and a respiratory airway; one or more skin covers, each capable of covering at least a portion of the user's face, wherein one or more of the fixation anchoring devices are connected to one or more skin covers; one or more conduits, each connected to at least a portion of one of the skin covers, wherein one or more of a gas, solid, liquid, and gel are transmitted through each of the conduits; and one or more sealing pads, each connected to at least one of one of the skin coverings and one of the fixation anchoring devices.
