A sanitary napkin comprises a cotton pad, and a blocking protective pad disposed on the cotton pad. The blocking protective pad surrounds a plurality of separation grooves arranged at intervals along the longitudinal direction and communicated with the cotton pad. Menstrual blood will be absorbed by the cotton pad through the separation grooves. The menstrual blood that cannot be absorbed in time will be blocked by the blocking protective pad and be located in the separation grooves, so as to prevent the menstrual blood from flowing around and leaking. Even if the user is leaning, the menstrual blood will still be blocked by the blocking protective pad with a certain thickness that is disposed on the cotton pad, so as to prevent rear leakage. Furthermore, the separation grooves prevent the blocking protective pad from contacting the user by the whole surface, so as to enhance the breathability and usage comfort. In other words, through the breathable design for forming gaps among each of the separation grooves, the contact area with human skin is reduced, and it will be more breathable and dry for usage.一種衛生棉,包含一棉墊,及一設於該棉墊上的擋阻護墊。該擋阻護墊圍繞出多個沿前後方向相間隔排列且連通該棉墊的隔離凹槽。經血是經由該等隔離凹槽而被該棉墊吸收,來不及吸收的經血會被該擋阻護墊擋止而位於該等隔離凹槽內,從而避免經血四處流動而外漏。即使使用者傾斜,經血仍會被設於該棉墊上而具有一定厚度的擋阻護墊攔止,有效避免後漏之情形。此外,該等隔離凹槽使該擋阻護墊並非整面貼觸使用者,利於透氣而能提升使用舒適度,意即藉由每一隔離槽所形成具有空隙的透氣設計,使得接觸人體皮膚的面積變小,使用上更加透氣乾爽。2‧‧‧衛生棉3‧‧‧棉墊4‧‧‧擋阻護墊40‧‧‧隔離凹槽
