Hemostatic gauze with low blood sucking amount for emergency treatment
Technical Field
The invention relates to the field of sanitary materials, in particular to a hemostatic gauze with low blood suction amount for emergency treatment.
The background technology is as follows:
Gauze dressing is a relatively conventional first-aid hemostasis and fixation method nowadays, and the mechanism is that blood flows out slowly by pressing peripheral blood vessels of a wound through gauze, and gaps among gauze yarns absorb blood to fix blood cells and coagulation factors on the surface of the wound, so that blood coagulation near the wound is assisted to perform hemostasis; auxiliary parts such as splints and the like can be used for wrapping and fixing limbs when necessary.
However, the traditional medical gauze has the problem of excessive blood absorption capacity because the gauze needs blood to infiltrate the periphery of the wound to play a role in stopping bleeding, and particularly causes greater damage to patients suffering from excessive blood loss; meanwhile, the gauze is used for first aid for the personnel who are not specially trained, so that the conditions of inconvenience in operation, misoperation and the like are easy to occur, and the best first aid opportunity of wounded persons is delayed; therefore, hemostatic gauze which can effectively stop bleeding and is convenient to use while reducing the blood sucking amount is always paid attention to the medical community of all countries in the world.
The invention comprises the following steps:
the embodiment of the invention provides a hemostatic gauze with low blood absorption amount for emergency treatment, which aims to solve the problems of excessive blood absorption amount and inconvenient use of the traditional medical gauze in the hemostatic process.
The technical solution of the invention is as follows:
A hemostatic gauze with low blood sucking amount for emergency treatment, which is characterized in that: comprises a degreasing gauze layer, a blended gauze layer, a hydrophobic gauze layer and a cotton gauze wrapping layer; the degreasing gauze layer, the blended gauze layer, the hydrophobic gauze layer and the cotton gauze wrapping layer are rectangular with the same shape; the absorbent gauze layer is directly contacted with the wound to absorb blood and promote coagulation; a blended yarn cloth layer is arranged on the degreasing yarn cloth layer, and the blended yarn cloth layer is made by blending degreasing yarns and hydrophobic yarns; a hydrophobic yarn cloth layer is arranged on the blended yarn cloth layer, and the hydrophobic yarn cloth layer is made by blending hydrophobic yarns; a cotton yarn wrapping layer is arranged on the hydrophobic yarn cloth layer; a plurality of high polymer polyester splints are arranged between the cotton yarn wrapping layer and the hydrophobic yarn cloth layer at intervals in parallel; 3 nylon hook strips are arranged on the cotton yarn wrapping layer at intervals in parallel; 3 nylon velvet belts are arranged at one side of the cotton yarn wrapping layer in parallel at intervals, and one end of each nylon velvet belt is fixed between each nylon hook belt and the cotton yarn wrapping layer; the nylon hook strips and the nylon velvet strips are connected at one end corresponding to each other in pairs, and the direction of the nylon hook strips is perpendicular to the high polymer polyester clamping plate.
The nylon hook belt and the nylon velvet belt have opposite fabric surface directions, and the nylon velvet belt can be mutually fixed with the nylon hook belt after encircling the limb part for a circle, so that the invention is tightly fixed on the wound surface.
The top view of the high polymer polyester splint is in a round rectangle, the cross section is in a flat arch shape, the arc surface of the high polymer polyester splint is in contact with the cotton yarn wrapping layer, the plane of the high polymer polyester splint is in contact with the hydrophobic yarn cloth layer, and the four corners of the high polymer polyester splint are provided with thinner fixing holes; after the nylon hook belt and the nylon velvet belt are integrally fixed, the high polymer polyester splint plays a role in fixing injured limbs.
After the scheme is adopted, the degreasing gauze layer is woven by degreasing yarns, on one hand, the blended gauze layer has strong water absorption, can directly contact with a wound to absorb blood and fix blood cells, and promotes blood to solidify near the wound to form a coagulation layer; the blended yarn cloth layer is arranged between the absorbent yarn cloth layer and the hydrophobic yarn cloth layer and is made of the absorbent yarn and the hydrophobic yarn in a blending way, on one hand, the blended yarn cloth layer has weaker hydrophobicity, after the absorbent yarn layer infiltrates blood, the absorption of hemostatic gauze to blood is limited, the blood absorption amount is reduced, and on the other hand, the blended yarn cloth layer can absorb part of blood to be used as a supplementing layer for absorbing the blood by the absorbent yarn cloth layer to stop bleeding, and a thicker coagulation layer is formed by absorbing a small amount of blood, so that the hemostatic effect on wounds with large bleeding amount can be kept better; the hydrophobic gauze layer is woven by hydrophobic yarns as the outermost layer of the invention, so that on one hand, the blended gauze layer has stronger hydrophobicity, prevents the hemostatic gauze from absorbing blood and reduces the blood absorption amount; the nylon velvet belt can encircle the limb part for a circle and then is mutually fixed with the nylon hook belt, so that the nylon velvet belt is tightly fixed on the surface of a wound, the wrapping length can be adjusted according to different injured parts, and the compression tightness degree can be adjusted according to different injured degrees; after the nylon hook belt and the nylon velvet belt are integrally fixed, the high polymer polyester splint plays a role in fixing injured limbs, other auxiliary materials are not needed, and the rectangular shape of the round angle ensures the comfort in the use process; in conclusion, the parts cooperate to solve the problems of excessive blood absorption and inconvenient use of the traditional medical gauze in the hemostatic process.
