摘要:
A compress for dressing wounds contains a depot layer (1) for storing liquids. A guiding layer (2) is assigned to the side of the depot layer (1) which faces the front side of the compress, which guiding layer is constructed in such a manner that the secretion which reaches it can spread out predominantly along said layer (2), before it reaches the depot layer (1). In order to achieve this effect, channels (3) are formed in the surface of the guiding layer (2) which faces the front side of the compress. Said channels (3) extend in the direction of the surface of the guiding layer (2). The two layers (1, 2) are arranged between a surface ply (10) and a lower sealing layer (15), the edges (16, 17) of which are bonded. Liquids which reach the surface layer spread out rapidly and evenly over the entire surface of the compress.

A nasal pack syringe is provided that includes a barrel, a plunger, an expandable, absorbent packing material, and a suture for retrieval of the packing material. The barrel is substantially rectangular in cross-section. The dimensions of the barrel and packing material are influenced by the dimensions of the human nasal cavity. The barrel and packing material are of sufficient length to allow penetration as far as the posterior wall of the nasopharynx. The barrel has ribs projecting from an interior wall thereof to facilitate movement of the packing material and a notch for holding the suture to avoid any obstruction during the movement of the packing material relative to the barrel. The plunger has a split end to assure a tight fit between the plunger and the barrel. In using the nasal pack syringe, the plunger is moved to push the packing material from the barrel into the patient's nasal cavity. The packing material expands upon contact with blood. The packing material absorbs the blood to prevent aspiration of the blood by the patient. Once expanded, the packing material applies hemostatic pressure to ruptured vessels to arrest the flow of blood. Retrieval of the packing material is accomplished by the suture attached to the packing material.

A composite sheet material is highly absorbent toward aqueous fluids including blood and exudate and comprises a polytetrafluoroethylene fibril matrix and hydrophilic absorptive particles enmeshed in the matrix. The composite sheet material is useful as a wound dressing, as a drying material for non-aqueous solvents, and as a chromatographic material.

A dental sponge constructed of absorbent material, which may include portions of oxidized cellulose or gelatin sponge material to be used as a hemostatic aid, for controlling bleeding following oral surgery or tooth extraction. The absorbent material is provided with an impervious non-absorbent coating covering a substantial portion of said absorbent material, with the coating defining an opening exposing the absorbent material through which fluid can flow. The sponge can be constructed in a number of shapes, and can be provided with projecting tab means used for handling the sponge.
