Description

Wearable wound treatment device

The present invention relates to a wearable wound treatment apparatus, and more particularly, to a wearable wound treatment apparatus capable of effectively treating a wound site by using a light emitting module that helps wound healing and negative pressure.

According to various studies and clinical results, it has been found that when negative pressure is applied to a tissue area, the formation of granulation tissue is promoted, and a negative pressure treatment device that applies this phenomenon to the medical field is being used.

The negative pressure treatment device applies negative pressure to the wound to inhale exudates such as pus and swelling from the wound, and at the same time promotes the formation of granulation tissue in the wound to promote wound healing.

A conventional negative pressure treatment apparatus includes a negative pressure generating unit in which a negative pressure motor for generating negative pressure is installed, a tube transmitting the negative pressure atmosphere generated by the negative pressure generating unit to a wound, and a tube adapter disposed on the wound side and coupled to the tube. Tube adapters are also called connectors, heads, and the like. Conventional tube adapters are made of a hard material with high hardness. The tube adapter is sealed against the surrounding environment together with the wound area by a band so that the negative pressure atmosphere transmitted through the tube is efficiently transmitted to the wound side.

The band has an adhesive layer formed on the skin adhesive surface so that the tube adapter can be fixed to the skin. When the negative pressure atmosphere is transmitted to the tube through the negative pressure generating unit, when the negative pressure atmosphere is transmitted to the foam dressing, positive pressure is applied to the tube adapter by the vacuum pressure caused by the sealing between the foam dressing and the tube adapter. Pressurized.

In addition, the conventional tube adapter is made of a hard material, and when the tube adapter presses the wound area by the positive pressure applied to the tube adapter, the capillaries at the portion where the wound area and the tube adapter are in contact are pressed by the positive pressure applied from the tube adapter. do.

When such a situation occurs in a patient with poor blood circulation, the formation of granulation tissue on the wound side is delayed or in severe cases, tissue necrosis occurs as blood flow through capillaries is not smoothly performed.

As the wound area forms a closed space by the foam dressing and the film dressing, there is a risk of deteriorating the wound by infectious bacteria of the wound due to the sealed property, and accordingly, a method for solving this is required.
