The Manual of Maternal and Child Health Care replaces the original Manual of Maternal Health Care and Manual of Child Health Care, realizing the "five certificates in one" of maternity service certificate, pre-pregnancy eugenics health examination service certificate, maternal health care manual, child health care manual and vaccination certificate, and truly realizing "one-handed registration and full service". In addition, some parts of the country have simultaneously introduced the electronic handbook on maternal and child health care formulated by the local health and family planning bureau. Residents can download the "Handbook of Maternal and Child Health" APP by scanning the QR code in the township (street) family planning office that handles the birth registration service, the service institution that provides prenatal eugenics health examination (pre-marital medical examination), the maternal and child health clinic of primary medical and health institutions or the midwifery technical service institution, and register for use. For those who can't use the mobile App, each unit can issue paper manuals in combination with the actual situation. The electronic version of the Handbook of Maternal and Child Health can be downloaded from the APP store. You can view inspection records, self-records, record forms, mission libraries, basic materials, and maternal and child health manuals on the APP. If you lose the Handbook of Maternal and Child Health Care during pregnancy, you can bring your valid identity certificate and the pregnancy test report issued by the hospital to the original place where the Handbook of Maternal and Child Health Care was established. If the Handbook of Maternal and Child Health Care is lost after the birth of a child, you can bring your household registration book, ID card, child birth certificate and vaccination book to the issuing community hospital for replacement. For the contents recorded in the Handbook of Maternal and Child Health Care, the community generally keeps a copy, just look for the original record.
