宫颈帽(英語:Cervical cap),是女性用的屏障類避孕器具。宫颈帽可以蓋住子宮頸,讓精子無法由子宮外口(external orifice of the uterus)進入子宮

制作材料

[编辑]

宫颈帽是由软橡胶制成,形似一个薄膜。

使用方法

[编辑]

若要置入或是取出宫颈帽,第一個步驟是先洗手,避免有害細菌進入陰道[1]。宫颈帽需在性交前先套在子宮頸上[2],有些文獻指出在性刺激之前先將宫颈帽置入,可以降低置入位置不正確的風險[3]。大多數的文獻也建議在宫颈帽中加入殺精劑[2][1][3][4],不過也有文獻指出不一定要加殺精劑[5][6]

從最後一次陰道射精開始計算,宫颈帽需置入陰道6[3][4]至8個小時[2][6]才有效。建議宫颈帽需在72小時內移除(美國是建議48小時內)[2]。除了拋棄式的Oves宫颈帽外,宫颈帽可以清洗後儲存,之後再使用[7]。矽膠製宫颈帽可以煮沸進行消毒[8]。重覆使用的宫颈帽可以使用一年[9]及兩年[1]。 有些宮頸帽有一個方便取出的突起,不過也有些文獻提到宮頸帽和子宮頸接合的很密,無法直接拉出。若要取出宮頸帽,可以將手指放在宮頸帽的固定環上,再突然施力拉出,即可取出[10]
