摘要:
A chitosan biomaterial is frozen in aqueous solution to form a frozen chitosan structure from which water is removed by a prescribed freeze-drying process to form a sponge-like chitosan structure having a thickness and a density. The sponge-like chitosan structure is compressed by application of heat and pressure to reduce the thickness and increase the density of the sponge-like chitosan structure to form a densified chitosan structure. The densified chitosan structure is further preconditioned by heating the densified chitopsan structure according to prescribed conditions to form a wound dressing. The wound dressing possesses an adhesion strength and resistance to dissolution in high blood flow bleeding situations.

Disclosed are solid dressings for treated wounded tissue in mammalian patients, such as a human, comprising a haemostatic layer consisting essentially of fibrinogen and a fibrinogen activator, wherein the fibrinogen is present in an amount between 3.0 mg/cm2 of the wound facing surface of the dressing and 13.0 mg/cm2 of the wound facing surface of the dressing. Also disclosed are methods for treating wounded tissue.

Disclosed is a strip of bandaging material having Velcro® strips at either end on opposite sides of the material. An absorbent pad is fixed near one end and on the side opposite the Velcro® strip. On the side opposite the absorbent pad, an S hook is provided with one end fastened to the material and the other end free. The absorbent pad is located over the wound and the longer end of material is wound around the extremity and fixed in place with the Velcro® stripe at the near end of the material. The remaining material is passed through the hook and pulled back in order to apply pressure to the wound and reduce blood loss. The remainder of the material is wrapped around the extremity and secured in place with the Velcro® strip on the far end.
摘要:
A vehicle tire of a radial carcass construction with a low cross-sectional profile having a tread portion that is reinforced by a belt layer is provided. The tread portion comprises a plurality of circumferential tread element bands in a center portion of the tread portion and one shoulder tread element row on either side of the center portion. The tread element bands are separated from one another and from the tread element rows in an axial direction of the vehicle tire by respective circumferential grooves that have straight edges. The tread element bands have notches that are distributed in a circumferential direction of the vehicle tire and are oriented at a slant relative to a center plane of the vehicle tire. The notches start at the circumferential grooves and end within the tread element bands. The shoulder tread element rows comprise tread elements that are separated from one another by transverse grooves and are arranged transverse relative to the center plane of the tire. The tread element bands comprise a central tread element band and respective adjacent tread element bands on either side, whereby at least the central tread element band has a central narrow circumferential groove arranged in the central tire plane. The central narrow circumferential groove has straight edges and is 1/4 to 1/3 as wide and essentially as deep as the other circumferential grooves. At least the adjacent tread element bands are provided with narrow grooves that are spaced relative to one another by a circumferential length of a double tread element repeating unit whereby the narrow grooves are essentially as deep and 1/4 to 1/3 as wide as the circumferential grooves. The narrow grooves and the notches are arranged in an alternating fashion.
摘要:
A first aid package for emergency use in the field for treating and transporting seriously burned patients. The first aid package comprises a soft resilient water absorbent foam material placed on a flexible waterproof outer covering having a pair of interlocking portions. A sterile sheet is placed over the resilient foam material and the sheet and the foam are saturated with an aqueous solution. The burn patient is placed on the sterile sheet and completely covered by the sterile sheet thereby enclosing the patient in a sterile atmosphere. An aqueous solution is then poured over the sheet so as to completely saturate the sheet and the uppermost portion of the patient. The cooperating interlocking portions of the flexible waterproof covering are placed completely around the sheet and the patient and locked into position thereby maintaining the patient in a sterile moist atmosphere. Openings are provided in the waterproof covering to provide access to the patient's arms and legs for intravenous blood transfusions should that be necessary. A pair of flexible straps located on each side of the waterproof outer covering provide the means for transporting the patient while in the sterile and moist protective cocoon environment.
