Abstract

A bandage/diaper drying device includes a gas inlet and channels formed between two layers of a very thin material (e.g. plastic). A spiral tube is positioned between the two layers to reduce occlusion of the layers and maintain flow of gas from the inlet to vents that are directed to a potential source of moisture. The vents are formed on a peripheral distribution channel that is in fluid communication with the gas inlet. In a preferred embodiment, each vent has a one-way duckbill valve allowing for the flow of gas from the peripheral distribution channel to dry a diaper/bandage in which the bandage/diaper drying system is mounted. The one-way duckbill valves reduce backflow of foreign matter into the peripheral distribution channel.

Core Innovation

A bandage/diaper drying system provides a gas inlet connected to a gas distribution channel and configured to deliver gas to a plurality of vents. The gas distribution channel is formed for fluid communication with the gas inlet and includes a crush-resistant or occlusion-resistant spacing member located within or around the channel. The spacing member maintains the gas distribution channel open to resist occlusion under conditions that would otherwise collapse the channel.

In the described structures, the gas distribution channel is formed from two sheets of planar material affixed to each other on opposing edges of the gas distribution channel. A spiral tube traversing an inside length of the gas distribution channel, or a spiral tube formed around the spiral tube spacing, holds the gas distribution channel open and provides a crush-resistant or occlusion-resistant spacing member. A plurality of vents are interfaced to the gas distribution channel such that each vent is in fluid communication with the gas distribution channel.

The system further includes vent structures that control fluid communication at the vents, including check valves. Each vent check valve allows flow of gas out of a corresponding vent while reducing a flow of contaminates into the corresponding vent and the gas distribution channel. In particular embodiments, the check valves are duckbill valves to allow gas out while reducing backflow of foreign matter or contaminates into the distribution channel.

Claims Coverage

The partial content provides three independent claims. Across these independent claims, the inventive coverage centers on a bandage/diaper drying system using a gas inlet feeding a gas distribution channel held open by a spiral tube, with vents that include check valves, including duckbill valves, to reduce contaminates backflow into the channel.

Across the independent claims, the core claimed arrangement is a bandage/diaper drying system with a gas inlet feeding a gas distribution channel held open by a spiral tube, where the channel is formed from two sheets affixed on opposing edges and includes vents. The independent claim set further characterizes vent flow control using check valves, including duckbill check valves, to allow gas out while reducing contaminates backflow into the vents and the gas distribution channel.
