Skull structure of simulation fetus teaching aid

Abstract

The invention discloses a skull structure of a simulation fetus teaching aid, the skull comprises a left forebone, a right forebone, a front fontanel, a left top bone, a right top bone, a rear fontanel, an occipital bone, a left temporal bone and a right temporal bone, and the left forebone, the right forebone, the left top bone, the right top bone, the occipital bone, the left temporal bone and the righttemporal bone are skulls, made of hard materials and placed and connected according to own positions. A cranial seam is reserved at the joint of each skull; and an elastic connecting piece isarranged at the lower part in the skull seam and is respectively connected with two adjacent skull bones. The skull of the infant teaching aid is separated according to the skull part and then connected through the elastic connecting piece, the state that the head of a fetus is slightly deformed due to extrusion during delivery can be simulated, the front fontanel and the rear fontanel which are made of soft materials are clamped through the pressing pieces, meanwhile, the hood which is soft in hand feeling and obvious in partition is arranged, and the model simulation degree is improved; andthe intuitive feeling during obstetric nursing teaching can be improved.

Description

technical field

[0001] The invention relates to the field of obstetric nursing teaching, in particular to a skull structure of a simulated fetal teaching aid. Background technique

[0002] When teaching obstetrics, it is necessary to simulate the state of the fetus during normal delivery so that students can better understand and learn. The skull of the fetus is composed of frontal bone, temporal bone, parietal bone and occipital bone. It is plastic. There are cranial sutures between the skull bones, and there is soft tissue covering between the cranial sutures and fontanel. During delivery, the cranial sutures will be slightly squeezed Overlap makes the diameter of the fetal head smaller, which is conducive to the delivery of the fetal head. In the existing teaching aids for babies, the head is usually not assembled according to the composition of the skull, but is made into a whole with a fixed size, which cannot simulate the state of the fetal skull being slightly deform...
