Embodiment Construction

[0039] Please check Figure 1 to Figure 5 , a medical device for managing exudation from damaged tissue, comprising a base layer 1 , a conductive layer (a conductive sponge layer in a specific embodiment) 2 , a liquid storage layer 3 and an air vent layer 4 . The material of the base layer 1 is silicone gel; the material of the conductive sponge layer 2 is black polyurethane sponge; the material of the liquid storage layer 3 is a hydrophilic gel fiber material; the material of the exhaust layer 4 is Skin tone polyurethane membrane to make the vent layer impermeable, breathable but water vapor permeable.

[0040] The base layer 1, the conductive sponge layer 2, the liquid storage layer 3, and the vent layer 4 have parts connected together in sequence. In the specific structure: the vent layer 4 has a first central area 41 and surrounds the first center The first edge area 42 of the area 41, the first central area 41 is the area part aligned with the front side of the liquid st...

Abstract

The invention discloses a medical device for managing damaged tissue exudate. The medical device comprises a basal layer, a conducting layer, a liquid storing layer and an exhaust layer which are connected together in an assembling manner, and the basal layer, the conducting layer, the liquid storing layer and the exhaust layer have parts which are sequentially connected together; the liquid storing layer and the exhaust layer form a liquid storing and exhaust part; negative pressure holes formed in a penetrating manner are formed in the liquid storing and exhaust part; an exudate through holeis formed in the basal layer in a penetrating manner; the exhaust layer has a first central region of which at least one part faces the top surface of the liquid storing layer and a first edge regionsurrounding the first central region; and the air permeability of the first central region of the exhaust layer is greater than that of the first edge region.

Description

technical field [0001] The present invention relates to medical devices, and more particularly to medical devices for managing exudate from damaged tissue. Background technique [0002] Connect a special medical device for managing the exudate of damaged tissue with a negative pressure suction pump and stick it on the affected area, so that the affected area can reach a state of negative pressure, so as to achieve the purpose of treating the affected surface. This approach has long been an effective treatment for promoting the healing of damaged tissue. The method can effectively control the infection of the damaged tissue and promote the healing of the damaged tissue. Such as CN108378988A, which discloses a built-in comprehensive flushing negative pressure sealing drainage device, comprising a porous foam whose lower surface is in contact with the wounded surface of the patient's skin. A drainage channel, a flushing channel and a catheter support are provided, and the fro...
