Fetal head model with movable skull

Abstract

The invention relates to the field of medical technology, and concretely relates to a fetal head model with a movable skull, which can more truly and intuitively reappear an external bony structure state during delivery of a baby. The fetal head model comprises an external bony structure, a fetus scalp layer and a supporting inner core, wherein the supporting inner core is arranged in the external bony structure; the fetus scalp layer is arranged at the outer part of the external bony structure; the external bony structure comprises a face part structure, an occipital bone part, a left-side parietal bone part and a right-side parietal bone. The face part structure, the occipital bone part, the left-side parietal bone part and the right-side parietal bone are independent on upper edges of ears of a fetus, so that a sutura and fontanel structure of the fetus is displayed; the fetus scalp layer is attached onto the four part structures, so that the four part structures can be independent and are connected through the scalp layer, and a complete fetus head top is formed; the four part structures are merged at the lower edges of the ears of the fetus, so that the whole bony structure is merged and connected into a whole. The fetal head model provided by the invention can more truly and intuitively reappear the external bony structure of the fetal head, and the fetal head model with the movable external bony structure can lifelikely reappear states of overlapping the external bony structure and deforming a fontanel when demonstrating a delivery mechanism.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a fetal head model with a movable skull that more realistically and intuitively reproduces the state of the external bony structure when the fetus is delivered. Background technique [0002] According to the skeletal development characteristics of the fetal head, the sutures of the external bony structure of the fetal head are not closed when the fetal head is delivered, and the bone fragments of the external bony structure are independent and movable, and the external bony structure of the fetal head can move during the compression of the birth canal. Even the bone seams overlap to achieve the purpose of adapting to the smooth delivery of the birth canal. In order to ensure the plasticity of the fetal head, the existing fetal head model usually molds the external bony structure as a whole. Even though there are lines or grooves between the external bony structures as bone seam ...

Problems solved by technology

Due to the lack of related models at present, the teaching effect has been seriously affected by relying on the teacher's oral explanation without model demonstration.

Even in the delivery process of real patients, this mechanism can only be discovered and judged by the midwife during the vaginal examination. Due to the protection of patients and the requirements of medical ethics, it is difficult for students to experience it personally.
