APPARATUSES AND METHODS FOR NEGATIVE PRESSURE WOUND THERAPY

Disclosed herein are several embodiments of a negative pressure appliance and methods of using the same in the treatment of wounds. Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, for example using softer, kink-free conformable suction adapters.

Chamber cushion, seal and use thereof

A device and method for creating and/or maintain an obstruction free upper airway passage. The device configured to fit under the chin of a subject adjacent to the subject's at an external location corresponding approximately with the subject's internal soft tissue associated with the neck's anterior triangle. The device including structural elements designed to optimize comfort, compliance and seal achieved through minimizing the pressure variation along the contact surface of the cushion element. The structural elements of the cushion may include a fluidly sealed chamber that may vary in thickness and width, a compressible elastic foam contained within the fluidly sealed chamber a ribbon layer backing the elastic foam contained within the fluidly sealed chamber and an adhesive layer disposed on the outer surface of the fluidly sealed chamber of the therapy device designed to contact the skin of the subject.

Wound therapy system with internal alternating orifice
11491054 · 2022-11-08 · ·

A wound therapy system includes a dressing sealable over a wound and defining a wound space between the dressing and the wound, tubing fluidly communicable with the wound space, and a canister fluidly communicable with the tubing. The canister, the tubing, and the dressing define a sealed space that includes the wound space. The wound therapy system also includes a therapy unit coupled to the canister. The therapy unit includes a sensor configured to measure a pressure in the sealed space, a valve positioned between the sealed space and a surrounding environment and controllable between an open position and a closed position, and a control circuit. The control circuit is configured to control the valve to alternate between the open position and the closed position to allow airflow through the valve, receive measurements from the sensor, and determine a volume of the wound space based on the measurements.

Systems and methods for using negative pressure wound therapy to manage open abdominal wounds

Embodiments disclosed herein are directed to the treatment of wounds using negative pressure. Some embodiments disclosed herein provide for a foam pad, which may be suitable for use in abdominal wound sites, and which may be sized in a dimensionally-independent manner. Additional embodiments provide for a wound contact layer, as well as a system for the treatment of abdominal wounds.

Advanced Wound Dressing For Incisional Wounds That Provides Apposition Forces As A Result Of Fluid Absorption
20220331166 · 2022-10-20 ·

A dressing for the treatment of incisional wounds includes an upper cover, a patient interface layer, and an absorbent material. The upper cover is configured to substantially cover the incisional wound. The upper cover includes a drape and a plurality of spines coupled to the drape. The drape includes a first side and a second, wound-facing side. The patient interface layer is coupled to the second side of the drape and includes a plurality of openings that are configured to receive fluid from the incisional wound. The absorbent material is disposed between the second side of the drape and the patient interface layer.

Systems and methods for controlling operation of a reduced pressure therapy system

Negative pressure wound therapy apparatuses and dressings, and systems and methods for operating such apparatuses for use with dressings are disclosed. In some embodiments, controlling the delivery of therapy can be based on monitoring and detecting various operating conditions. An apparatus can have a controller configured to monitor the duty cycle of a source of negative pressure and, based on the monitored duty cycle, determine whether a leak is present. The controller can be configured to provide an indication that a leak is present. For example, the controller can be configured to suspend and/or pause the delivery of therapy, and to restart the delivery of therapy due to a timeout, request from a user, etc. In addition, the controller can be configured to pause and/or restart the delivery of therapy upon a request from the user, such as in response to the user operating a switch.

First responder device
11622755 · 2023-04-11 · ·

A first responder device for treating blood flow from a deep wound or a bodily cavity having an inflatable balloon, a first chamber accommodating a liquid arranged for inflating the balloon, a second chamber accommodating a cooling agent capable of dissolving in the liquid when coming in contact therewith, thereby lowering the temperature, a rupturable seal between the first and second chambers, and a structure for forcing the liquid out of the first chamber into the inflatable balloon, and for rupturing the rupturable seal.

WOUND CONTACTING MEMBERS AND METHODS
20230141228 · 2023-05-11 ·

Wound contacting members and methods, apparatuses, systems and kits incorporating the same are disclosed. The wound contacting members offer improved performance in terms of preventing or inhibiting tissue in-growth and improving tissue granulation growth. The wound contacting members may be used in negative pressure wound therapy (NPWT) applications.

SHEAR RESISTANT WOUND DRESSING FOR USE IN VACUUM WOUND THERAPY
20230190534 · 2023-06-22 ·

A cover layer for a vacuum wound therapy dressing includes a backing layer formed from a flexible polymeric membrane and an adhesive layer for affixing the backing layer over a wound bed to provide a substantially fluid-tight seal around a perimeter of the wound bed. The cover layer is reinforced with a reinforcement layer extending to a peripheral region of the backing layer to distribute forces associated with evacuating a reservoir, as defined by or within the cover, to stimulate healing of the wound bed.
