Embodiment Construction

[0115] The present invention will now be described in further detail with reference to the accompanying drawings and examples, which should not be construed as limiting the present invention.

[0116] Figure 1a with Figure 1b The system of the invention is shown wherein the wound dressing is connected to the fluid container (11) via a tube (5) adapted for use with a peristaltic pump. A pressure control valve (13) is connected close to the wound dressing, which limits the negative pressure generated at the wound site to a predetermined value. Fluid container (11) can be rigid or flexible container, so that accord with patient condition (below image 3 This will be described in further detail). The container has an inlet (2) and an outlet (4). A peristaltic pump (3) is used between the container (11) and the wound dressing (15). Tube (5) is connected by a peristaltic pump. The container has means to allow the gas to escape, such as a vent or valve (1) at the outlet (i.e.,...

Abstract

The invention provides a device comprising a wound dressing (15) connected via a pump (3) to a fluid container (11), wherein said wound dressing communicates with a mechanical pressure control valve (13), said fluid container being provided with an inlet (2) and exit (4). Also provided is (i) a flexible fluid container comprising at least two films with integrated vents, (ii) a wound dressing and (iii) a multi-compartment wound fluid container (20, 35, 63) comprising at least two inner Compartment, and be provided with outlet (31,37,51) and inlet (19,49), wherein said vessel comprises the microporous fluid separator (29,41,55) that separates described at least two internal compartments , wherein the microporous fluid separator allows gas communication between the compartments and prevents fluid flow to the outlet of the container. Other devices provided include means for detecting the level of fluid in the multi-compartment wound fluid container. The present invention also provides systems for applying subatmospheric pressure to a patient's wound dressing by using the devices and devices of the invention, and methods of treating wounds using the devices, devices and systems of the invention.

Description

technical field [0001] The invention relates to a device for negative pressure wound therapy (Negative Pressure Wound Therapy, NPWT) of a patient's exposed wound. Background technique [0002] Negative pressure wound therapy, reduced pressure therapy, or subatmospheric pressure therapy is used to treat difficult-to-heal wounds and works by applying subatmospheric pressure (typically between 50 mmHg and 200 mmHg gauge) to a porous dressing that sits on the wound. The porous dressing is usually held in place with a partially enclosed adhesive film, with tubing connecting the dressing assembly to a rigid fluid container fitted with a pressure generating device consisting of a low flow vacuum pump, a reservoir for the fluid container, Control system and moldings to house the components. In a typical setup for clinical use, a control system activates a pump which in turn evacuates the dressing and draws air and fluid from the wound dressing site, which is drawn into a rigid cont...
