Reduced pressure therapy devices

Принадлежит: Leland Stanford Junior University

Described generally herein are tissue therapy devices, which may comprise a sealant layer and a suction apparatus. The sealant layer functions so as to create a sealed enclosure between it and the surface of a patient by forming, preferably, an airtight seal around an area of tissue that requires negative pressure therapy. The tissue therapy device may comprise a suction apparatus. The suction apparatus is typically in fluid communication with the sealant layer and functions so as to reduce the amount of pressure present underneath the sealant layer. The reduced pressure is self-created by the suction apparatus. Together the sealant layer and the suction apparatus preferably create a closed reduced pressure therapy system. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of the air molecules under the sealant layer.

Vacuum therapy is an effective way to treat complex open wounds. Today, most of the equipment is very expensive to provide widespread use of this therapy and, most of them, are designed to in-patient use. Also, there are difficulties to obtain the needed materials in the same package for specific use of treating open wounds, which causes delay in the treatment. We designed a kit that is cost-effective and ready-to-use to be used with Jackson-Pratt or Portovac style suction drains that allows a cheap, out-patient alternative for use in open-wound situations. We devise that this system could be used in emergency situations where there is a hostile environment such as natural catastrophes, war and emergency situations, as well as to regular in and out-patient wound care.

The engineered tissue implant may be understood as a transplantable cell construct or as an implantable bioreactor for cell growth both in vitro and/or in vivo. A method to provide tissue for reconstruction may comprise forming the engineered tissue implant containing a scaffold, introducing and seeding cells to the scaffold, introducing a perfusion fluid to the scaffold which flows through the fluid flow passage and scaffold, proliferating the cells within the scaffold and forming blood vessels within the scaffold. This may be followed by transplanting the engineered tissue implant in vivo where nutrition and oxygen are provided to support the preloaded cells.

Surgical cavity drainage and closure system

Номер: US20140039468A1
Автор: Raymond M. Dunn
Принадлежит: University of Massachusetts UMass

A surgical drain device includes an adhesion matrix of biodegradable polymer material and a plurality of drain tubes attached to the matrix. The device is implanted within a surgical wound to treat the presence of seromas, for example, and is used to promote drainage, tissue adhesion, and wound closure. The drain tubes converge into a common collection tube that leads wound fluid outside the body under gravity feed or negative pressure applied to the collection tube. The matrix contains an array of apertures that allow tissue contact across the device. The device also can include a coating of surgical adhesive and a tissue anchoring system of hooks or barbs. The device and systems containing the device are particularly useful to promote the healing of surgical wounds from abdominal surgery.

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

Принадлежит: Resource Transition Consultants LLC

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.

A pump generates a vacuum at a wound site via first tubing. A negative pressure circuit is defined by a canister, the first tubing and the wound site. A controller of a therapy device operates the pump to apply a first negative pressure to the entirety of the negative pressure circuit, following which ambient air is allowed to flow into the negative pressure circuit. The controller also operates the pump to apply a second negative pressure to a selected portion of the negative pressure circuit exclusive of the wound site, following which ambient air is allowed to flow into the selected portion. A quantity of fluid to be delivered to the wound site via a second tubing is determined by comparing measured parameters related to the flow of air into the negative pressure circuit to parameters measured with respect to the flow of air into the selected portion.

Negative-pressure wound therapy apparatus

Provided is a negative-pressure wound therapy apparatus capable of causing negative pressure in a closed space defined by a wound dressing and a wound region with a sufficient suction flow rate as needed even with a miniaturized pump device. In atypical use that needs a high suction flow rate, because a pump device ( 30 ) with a high suction flow rate is attached to a wound dressing ( 10 ) and sucks gas from a closed space ( 904 ) defined by a wound region ( 903 ) and the wound dressing ( 10 ), even when a pump device ( 20 ) for typical use is miniaturized and the suction flow rate of the pump device ( 20 ) is reduced, a therapy apparatus ( 100 ) can achieve a suction flow rate sufficient for atypical use. Thus, the pressure value in the closed space ( 904 ) can decrease to a desired value more quickly.
