Do you know? Gauze rolls can be used to stop nosebleeds, let's take a closer look:
In recent years, a gauze roll specifically designed to stop bleeding has the same appearance as ordinary gauze, but can quickly absorb blood after meeting blood, and its blood absorption is more than 5 times its volume. "Hemostatic gauze" is made of ordinary degreased gauze through chemical treatment. The pH value is between 6.5 and 7.5, and the salt content is less than 1%. It is similar to human cells, so it has no stimulating effect on the human body and can Promote wound healing, the effect of using this special gauze to stop nosebleed is very satisfactory.
The hemostatic principle of hemostatic gauze is:
① Chemical hemostasis. After the hemostatic gauze encounters blood, it can generate a large number of negative ions, activate coagulation factors III and Ⅶ, and promote thrombin production. Under the catalysis of thrombin, plasma proteinogen quickly forms fibrin to form a clot, preventing bleeding.
② Physical hemostasis. After the hemostatic gauze meets the blood, it forms a very viscous colloid to close the blood vessels, preventing blood from flowing out and forming a covering with the clot to protect the wound surface; the gauze will quickly suck blood and expand its volume when it meets the blood, and it will play a role of mechanical compression to stop bleeding.
The specific method is: when the nosebleeds, twist the "hemostatic gauze roll" into a roll, rotate it into the nasal cavity, and lift it after 1 to 6 hours.
Its advantages are as follows:
① It has no toxic or side effects on the human body and no adverse reactions.
② Good hemostatic effect, suitable for use by various people, including sJ6) and patients.
③ Low price, easy to carry, can be used for family and travel.
