PORTABLE DEVICE WITH DISPOSABLE RESERVOIR FOR COLLECTION OF INTERNAL FLUID AFTER SURGERY
A device comprising: (a) a housing; (b) one or more pumps located within the housing, the one or more pumps configured to create a negative pressure and move fluid; (c) one or more connectors located at least partially within in the housing; (d) internal fluid paths connecting the one or more pumps to the one or more connectors; (e) one or more reservoirs connected to the one or more connectors, the one or more reservoirs being configured to collect the fluid moved by the one or more pumps; and (f) a processor configured to:(i) calculate a total volume of fluid collected in the one or more reservoirs; and (ii) indicate that the one or more reservoirs are full; wherein the fluid moved is a fluid from a wound or incision.
Wound dressing
A method and apparatus are disclosed for dressing a wound. The apparatus comprises a sealing layer comprising at least one orifice, an absorbent layer over the sealing layer, absorbing wound exude and a liquid impermeable, gas permeable filter layer over the absorbent layer.
Assembly for collecting fluid during a medical or a surgical operation
An assembly is disclosed for collecting fluid during a medical or a surgical operation. The assembly can include a canister having an openable lid and a collection liner. The collection liner can include a closed bag portion and an inlet for a collection container. The inlet has a first end and a second end, which opens into the bag portion. The bag portion is placed inside the canister. The first end of the inlet for a collection container extends from between the edge of the canister and the edge of the lid to the outside of the canister when the lid is closed.
SYSTEMS AND METHODS FOR APPLYING REDUCED PRESSURE THERAPY
Embodiments of negative pressure wound therapy apparatuses and methods for using such apparatuses are disclosed. In some embodiments, a negative pressure wound therapy apparatus includes a controller configured to determine a level of exudate in a canister (or a dressing) based at least in part on one or more characteristics of pressure signals generated by a negative pressure source and monitored by a pressure sensor. One such characteristic of the pressure signals can be amplitude, which may increase as a level of exudate in the canister (or dressing) increases. The canister (or dressing) can include a filter configured to become occluded in order to prevent overflow of the canister (or dressing). The controller can be additionally configured to detect and indicate a canister (or dressing) pre-full condition before the filter becomes occluded. More efficient and reliable operation of the negative pressure wound therapy apparatus can thereby be attained.
Controlled release iodine structure for use with wound care
Systems, methods, and apparatuses for generating and releasing iodine are described. Some embodiments may include a dressing member including a plurality of iodine-forming reagents and a water-swellable material. In some embodiments, the dressing member may include water-swellable fibers. The water-swellable fibers may each include a water-swellable material in which iodine-forming reagents are dispersed. As liquid comes into contact with and is absorbed by the water-swellable material, the iodine-forming reagents may come into contact with each other, causing an iodine-forming reaction to occur, producing iodine.
Portable device with disposable reservoir for collection of internal fluid after surgery
A system and apparatus for the collection of serous or serosanguinous fluid from a percutaneous site after surgery. A pump unit with one or more pumps or powered sources provide continuous negative pressure suction to draw fluid from the percutaneous site and pumps the fluid into disposable reservoirs with one-way valves that are easy to handle while maintaining sterility and a seal to prevent the loss of vacuum. Air is continuously removed from the reservoirs. Measurement and analysis of the output is performed automatically.
Method for the collection and use of amniotic fluid
Disclosed is a method for the collection, processing and reuse of amniotic fluid at a C-section site. The method is conducted coincident with and in the operating room wherein the caesarian section is performed. In the method, amniotic fluid is suctioned from the caesarian section collection site using a vacuum line system which includes a canister positioned along the vacuum line. The canister has a port whereby the amniotic fluid can be removed from the canister. The amniotic fluid can be then be mixed with a coagulant or sealant and applied to the wound site of the cesarean section patient. Placental aspirate may also be collected, processed and used in accordance with the method of the present invention.
ION EXCHANGE ENHANCED ABSORBENT SYSTEMS
A system, method, and apparatus for treating a tissue site with reduced pressure includes a dressing adapted to be positioned proximate the tissue site. An absorbent may be adapted to be fluidly coupled to the manifold, and an ion exchange member may be adapted to be fluidly coupled between the manifold and the absorbent. A sealing member may be adapted to cover the tissue site to form a sealed space having the manifold disposed therein. A reduced-pressure source may be adapted to be fluidly coupled to the manifold.
Dressing with asymmetric absorbent core for negative pressure wound therapy
Systems, methods, and apparatuses for treating a tissue site with reduced pressure are described. The system includes a manifold configured to be placed adjacent the tissue site, and a sealing member configured to be placed over the tissue site and the manifold. The system also includes a reduced-pressure source fluidly coupled to the manifold through the sealing member. The system further includes a pouch having an upstream layer having a first thickness, a downstream layer having a second thickness, and an absorbent member enclosed between the upstream layer and the downstream layer. The second thickness is greater than the first thickness. The upstream layer may have a hydrophilic side adjacent the absorbent member, and the downstream layer may have a hydrophobic side adjacent the absorbent member.
LOW PROFILE FILTER DEVICES SUITABLE FOR USE IN NEGATIVE PRESSURE WOUND THERAPY SYSTEMS
A filter adaptor includes a body that defines an internal passageway disposed between an inlet and an outlet, the passageway configured to permit passage of a fluid in a first direction defined by the inlet and the outlet; and a filter disposed within the passageway and oriented to define a volumetric direction that is different than the first direction. Another filter adaptor includes a body that defines an internal passageway disposed between an inlet and an outlet, and a filter disposed within the passageway, wherein the filter comprises a gelling absorbent material that, when in a dry state, is permeable to gas and that, when contacted by an aqueous fluid, converts to a gel. Such filter adaptors may be used for negative pressure wound therapy, dressing, or as syringe filters.
