AI Technical Summary

Technical Problem

Existing technologies have many shortcomings in meeting the human body's need for fluids and addressing the burden of fluids on the body. For example, breast pads tend to slip when used by women with flat breasts, NuBra loses its adhesiveness after repeated use, surgical implantation of fluid bags is painful and costly, infants and people with urinary incontinence face pain and infection risks when collecting urine, and urine collection bags are inconvenient to use and prone to leakage.

Method used

Design a fluid-carrying dressing comprising a first sheet, a second sheet, and a third sheet, which form a chamber and a drainage port by welding or bonding, and combine an adhesive layer and a release layer, possessing the characteristics of easy application, not easy to fall off, fluid-carrying capacity, and leak-proof, suitable for introducing maintenance/medical fluids or collecting body fluids.

Benefits of technology

It enables the temporary retention of fluid on the body surface, meeting the body's fluid needs, reducing the burden of fluid on the body, and is simple in structure, easy to use, and inexpensive, making it suitable for a variety of applications.

Abstract

The present application provides a fluid-carrying patch, comprising: a first sheet having a first surface and a second surface; a second sheet having a third surface and a fourth surface, wherein a portion of the third surface and a portion of the second surface are fused or adhered to each other in at least a strip-shaped area, thereby forming a first chamber having at least a first drainage port, the interior of the first chamber being in communication with the outside through the first drainage port; an adhesive layer disposed on the fourth surface of the second sheet; and a release layer covering at least a portion of the adhesive layer, wherein the first drainage port is an open portion formed at the adjacent edges of the first sheet or the first sheet and the second sheet, which are not fused or adhered to each other.
