A compression device includes an adhesion sheet including an adhesion surface; and a compression member mounted on the adhesion sheet and configured to compress a biological surface. The compression member includes a fixing portion fixed to the adhesion sheet on a side of the sheet opposite the adhesion surface in a thickness direction, and a compression main body portion provided in a portion of the compression member, in a plan view seen along the thickness direction, that does not overlap the adhesion sheet. The compression main body is configured to protrude or be protrusible further toward one side in the thickness direction than the adhesion surface. The adhesion sheet includes a first portion to which the fixing portion is fixed and a second portion to which the fixing portion is not fixed. The second portion is provided on at least a compression main body portion side of the adhesion sheet.

One aspect of the invention is a method of treating a wound to clot blood. A sponge material is applied to the wound. The sponge comprises a starch having hemostatic properties and at least one binding agent. The sponge may further comprise a porous, flexible material.

An inflatable device for insertion into a user's nose for controlling nasal exudation has an elongated shaft including at least one lumen for accommodating a fluid; an inflatable balloon connected to the shaft, the balloon being in fluid connection to the lumen; and an absorber for absorbing nasal exudates, the absorber being disposed at an outer circumference of the shaft and/or at a distal tip portion of the device. Another inflatable device for insertion into a user's nose for controlling nasal exudation has an elongated shaft including at least one lumen for accommodating a fluid; and an inflatable balloon connected to the shaft, the balloon being in fluid connection to the lumen; the balloon containing a cooling agent, wherein the cooling agent is configured to cool the balloon when coming into contact with the fluid.

The present invention resides in a sutureless wound closure device for external use. The device comprises a base layer for fixing the device to skin and an upper layer. The base layer includes an aperture therein. The upper layer has a first end anchored to the base layer and a second, opposite end that includes fixing means to attach the end to the base layer and close the aperture in the base layer.

A compression device set includes: a compression device to be adhered to a biological surface; and a cover member attachable to and detachable from the compression device. The compression device includes: an adhesive sheet having an adhesion lower surface to be adhered to the biological surface; and a compression member fixed to an upper surface side of the adhesive sheet and configured to compress the biological surface when the adhesion surface is adhered to the biological surface. The adhesive sheet includes a first portion that is in contact with the compression member and a second portion that is not in contact with the compression member. The cover member is configured to be attached to the compression member in a state in which the cover member is configured to come into contact with an upper surface of at least a part of the second portion of the adhesive sheet.

The present invention provides a hemostatic composite sponge comprising oxidized cellulose and an essentially gelatin-free bioadhesive material stably associated with said sponge and present in an organized pattern on said sponge.
