Problems solved by technology

[0005] The present invention mainly solves the problem that the current pelvic model and the fetal model are not effectively combined, the explanation is laborious and laborious, and the learners cannot accurately grasp the relevant knowledge. By providing a conveniently combined delivery mechanism model, the fetal model can be conveniently placed in the pelvis. Demonstration on the model, showing the relationship between different fetal positions and the sagittal suture of the fetal head, the size of the fontanel and the pelvic meridian during delivery. Moreover, the fetal model can be stuck in the slide rail of the pelvic model and rotate freely, freeing the operator's hands. It is convenient for detailed explanation and improves the learning efficiency of trainees

Embodiment 1

[0051] see first Figure 10 and Figure 11 , Figure 10 and Figure 11 It is a delivery mechanism model of this embodiment, including a pelvic model and a fetal model, which can be used in combination to demonstrate the delivery methods of different fetal positions of the fetus with head first or breech first, and the fetus model can be obtained from the pelvic model Pass through to simulate the childbirth process, and it can also be stuck near the meridian of the pelvic model, freeing hands, and conveniently explaining the relationship between the meridian of the pelvis and various parts of the fetal head.

[0052] Further, the pelvis model is made according to the actual proportion of the human body, and is preferably made of PVC material, which is easy to operate. The fetal model is made by reducing the actual size of the fetus by 20% to 30%, so as to facilitate the demonstration of the fetal model on the pelvic model and facilitate the passing of the fetal model through...

Embodiment 2

[0071] The first sliding rail 2 in Embodiment 1 needs to have a certain thickness so that the engaging portion 501 of the fetal model can be clamped on the inner ring 202 . In this embodiment, an embedded groove 203 is added inside the first sliding rail 2, see Figure 5 , the size of the embedded groove 203 matches the size of the steel ball of the engaging portion 501, so that the fetal model can be well locked in the inner ring 202 without falling. The thickness of the first slide rail 2 can be effectively reduced and the cost can be saved by simply reducing the size of the steel ball of the engaging portion 501 and the embedded groove 203 of the first slide rail 2 synchronously.

[0072] Further, the internal size of the embedded groove 203 is not larger than the opening size, preferably a rectangular groove, which is convenient for processing and manufacturing.

[0073] As a further preference, the opening width of the embedded groove 203 accounts for 2 / 3 of the inner th...

Embodiment 3

[0077] Combine below Figure 12-Figure 14 In this embodiment, in addition to the first track groove 101 inside the pelvis model main body 1, a second track groove 103 is also provided at the middle pelvic plane position, and a certain distance is reserved between the second track groove 103 and the first track groove 101. distance. The second track groove 103 can be used to place the second slide rail 3, and the inner size of the second slide rail 3 matches the size of the widest part of the fetal head and buttocks. Since the inner size of the pelvic plane in the pelvis model is smaller than the opening size of the upper entrance plane, the outer size of the second slide rail 3 needs to be slightly smaller than the first slide rail 2 . Simultaneously, the slightly smaller second slide rail 3 of outer dimension also can be conveniently inserted in the second track groove 103 from top to bottom, and when plugging in, the second slide rail 3 can be inclined downward near the end...

Abstract

A birth mechanism model, including a pelvis model and a fetal model, both of which are used in combination, the pelvis model includes left and right hip bones, sacrum and coccyx, and also includes an entrance plane, a middle pelvis plane and an exit plane, and each plane is connected to the pelvis A number of light sources are respectively provided at the joints of the models, and the light sources are arranged along the meridian direction of the pelvis. A slide rail is fixedly or detachably installed below the entrance plane, and the slide rail includes an outer ring (201) and an inner ring (202). The outer ring (201) does not rotate relative to the pelvis model, and the inner ring (201) The ring (202) can rotate freely relative to the outer ring (201), and the widest part of the head and / or buttocks of the fetal model is provided with a locking part (501), and the locking part (501) is provided with an elastic parts, and the engaging part (501) can be locked into the inner ring (202) of the slide rail under compression, and rotate with the inner ring (202). The delivery mechanism model frees hands, facilitates detailed explanations, and improves the learning efficiency of trainees.

Description

technical field [0001] The invention relates to the field of medical teaching models, in particular to a delivery mechanism model suitable for demonstration in families, hospitals and schools. Background technique [0002] Childbirth specifically refers to the period and process in which the fetus separates from the mother's body and becomes an independent individual. When the fetus is delivered from the mother's pelvis, the size and shape of the fetus and the length of the meridians of the pelvis are directly related to whether the delivery can proceed smoothly. Fully understanding the structure of the pelvis and the delivery process of the fetus will help reduce the fear of childbirth for pregnant women, and help medical staff master relevant techniques for prenatal examination, midwifery, perineal suture and other operations. [0003] However, the current pelvic models can only be used in the teaching of pelvic physiology and anatomy in disciplines such as anatomy, obstet...
