Using low-cost 3D-printed models of prenatal ultrasonography for visually-impaired expectant persons.

Background: For visually impaired or blind patients, the experience of pregnancy sets them apart from nondisabled people for whom viewing of the first ultrasound has become a social and emotional milestone.

Objective: We proposed the use of 3D-printed models to allow the societal inclusion of visually impaired or blind expectant parents.

Patient Involvement: Visually impaired expectant parents were proposed to touch a 3D printed sensory vector of their prenatal classic ultrasonography.
