If a woman is pregnant and does not require an abortion to terminate her pregnancy, she must have an ultrasound to confirm the diagnosis of intrauterine pregnancy and then undergo the procedure, which is as follows: 1. Have the woman lie flat on the surgical bed with her legs apart in the bladder stone position and expose the entire vulva. 2. Disinfect the woman’s vulva and vagina with iodophor three times, spread a sterile treatment towel, and dilate the woman’s vagina with a dilator to expose the cervix. 3. After determining the depth and location of the uterine cavity, you can use the dilation stick to dilate the cervix from small to large size, connect the negative pressure suction tube to the negative pressure suction device, set the pressure to about 500, and extend the negative pressure suction tube into the uterine cavity to suck out the pregnancy sac, and wait until you feel the cavity After feeling the roughness of the uterine cavity, the negative pressure suction device can be removed. 4. Disinfect the vagina again with iodophor, remove the cervical forceps and the dilator, and the operation can be finished.
