Abstract
1. According to the speed of blood flow, we can preliminarily judge what blood vessel is broken. If it is like a small fountain, it is mostly an artery rupture; Like a trickle, most of them have broken veins; Little by little, the capillaries are basically broken.

2. The blood-sucking amount of a sanitary towel is actually very small. Generally, the estimated amount of bleeding after using one tablet at night is 10-20ml.

3. After human body bleeds, it will immediately start the coagulation mechanism. Small capillaries burst and blood oozed. Leave it alone, it will coagulate by itself. Venules rupture, and many of them can coagulate themselves.

4. If there is serious bleeding outside the hospital that you think needs treatment, the simplest way is to stop the bleeding by pressing. You can use clean towels and sanitary napkins. In short, the cleaner the better, which can reduce the risk of infection.

5. The method of pressure dressing can be used again. The word pressure should be bold here, because just covering gauze has no hemostatic effect, but you should put some pressure on the bleeding position, and the principle is also to suppress hemostasis. If there is arterial bleeding, it is best to bandage the bleeding near the heart.

6. Nursing liquid is a kind of weakly acidic surfactant, which is more suitable for women's acidic environment than alkaline soap/laundry detergent/washing powder.

7. Menstruation refers to the periodic shedding and bleeding of endometrium, accompanied by periodic changes of ovary. The bleeding 1 day is the beginning of menstruation, and the interval between two adjacent menstruation on 1 day is called a menstrual cycle. Generally 2 1-35 days, with an average of 28 days. The duration of each menstrual period is called menstrual period, which is usually 2-7 days, mostly 3-5 days.

8. Many experiments have proved that the probability of dysmenorrhea of girls with exercise habits is significantly lower than that of girls who generally don't exercise much.

9. Moderate intensity exercise and fitness during menstruation will not cause harm to the body. On the contrary, it will have a positive effect on the relief of dysmenorrhea and physical health.

10. Half of the androgens in women are secreted by adrenal glands, and the fluctuation is relatively small. Estrogen in women is mainly secreted by ovaries, which fluctuates greatly during the menstrual cycle.

1 1. Either the east wind overrides the west wind, or the west wind overrides the east wind. When estrogen is strong enough, the effect of androgen will be inhibited, while when estrogen level is low, the effect of androgen will be prominent.

12. It is not necessarily considered that picking menstrual towels is a technical job. In fact, there are many aspects that need attention, including sensitization, hygroscopicity, health indicators, adhesion, leakage prevention and so on.

13. Water-absorbing beads actually have a special name: polymer water-absorbing resin, the main component of which is polypropylene cross-linked resin, which can absorb 500 to 1000 times its own water. Mainly produced in the United States, Korea, Japan and Singapore.

14. A menstrual towel with fluorescent agent is definitely not a good thing. Because fluff pulp itself has undergone a very fine treatment, it only needs to be pressed into velvet, which is as white and soft as cotton and has low dust. Only by using inferior pulp or even recycled pulp products will there be a need to increase whiteness, and fluorescent whitening agents will be added. Test method: tear open the inner core and use a 365nm ultraviolet flashlight to know whether there is fluorescence.

15. PMS is a series of mental and physical symptoms related to the physiological cycle. It is difficult to distinguish it from the diagnosis of emotional problems, and it is usually based on whether it occurs before menstruation.

16. No soul. My body is my soul. If there is anything wrong with more than one kilogram of nerve cells, my soul will go to hell alive.

17. A large part of the pathological risk factors of dysmenorrhea are related to life. Smoking, drinking, depression, lack of exercise and life stress are all causes of dysmenorrhea, which is scientifically based.

18. Hormones are called primary dysmenorrhea and can be relieved by using non-steroidal anti-inflammatory drugs, such as ibuprofen. After the birth, the production process of this thing was re-developed, just like reinstalling the system, and it was normal.

19. The best way is to have children. Pregnancy has a great inhibitory effect on this disease, and many bleeding places will be filled with high estrogen and progesterone levels.
