Medical gauze can be used to stop nosebleed
In recent years, we have developed a kind of gauze specially used for hemostasis. Its appearance is the same as that of ordinary gauze, but it can quickly absorb blood when it meets blood, and the blood volume is more than 5 times of its volume. "Hemostatic gauze" is made of ordinary degreasing gauze after chemical treatment, with pH value of 6. 5~7。 It has no stimulation to human body and can promote wound healing. The application of this special gauze is very satisfactory in stopping nosebleed.
The hemostatic principle of hemostatic gauze is as follows:
Medical absorbent gauze block
① Chemical hemostasis. Hemostatic gauze can produce a large number of negative ions, activate coagulation factor and VI, and promote the generation of thrombin. Under the catalysis of thrombin, plasma proteogen rapidly forms fibrin to form clot and prevent bleeding.
② Physical hemostasis. When the gauze meets blood, it will form a very sticky colloid to seal the blood vessels, prevent the blood flow out and form a covering together with the blood clot to protect the wound surface; when the gauze meets with blood, it will quickly absorb blood and expand the volume, playing the role of mechanical compression hemostasis. The specific method is: when epistaxis occurs, twist the "hemostatic gauze roll" into a roll, rotate and plug it into the nasal cavity, and lift it after 1-6 hours.
Its advantages are as follows:
① It has no toxic side effects and no adverse reactions.
② The hemostasis effect is good. It is suitable for all kinds of people, including S1,) 6 and patients.
③ Low price, easy to carry, can be used for family and travel.
