Postpartum pelvic restorer is a kind of machine that stimulates and massages acupoints to make pelvic floor muscles contract, separate bones recover, ligaments recover elastically, and help lying-in women restore the pelvis opened due to childbirth.

However, an obstetrician and gynecologist in a public hospital said that 42 days after delivery is the puerperium, and the so-called "pelvic relaxation" will generally recover naturally after delivery with the gradual decline of pregnancy-related physiological hormones. It is not suitable to repair by squeezing bones, tying bandages and pressing machines.
