A teaching model and its operation method for skill training of labor process observation

Abstract

The invention relates to a teaching model for labor observation skill training and an operation method of the teaching model for labor observation skill training. The teaching model comprises a half body buttock profile modeling mold, an anus and perineum integrated profile modeling mold and a belly profile modeling mold. A profile modeling vaginal orifice and a profile modeling anus opening are formed in the anus and perineum integrated profile modeling mold, a profile modeling pelvic cavity is formed in the lower portion inside the half body buttock profile modeling mold, a profile modeling spine is manufactured at the front end of the profile modeling pelvic cavity, a guide rail is arranged in the direction of the profile modeling spine and provided with a control rod, the head of the control rod is provided with a camera provided with an infrared night vision lamp, a profile modeling baby head made of transparent materials is installed outside the camera, a connecting line is arranged on the camera, and the profile modeling baby head is matched with the profile modeling vaginal orifice or a profile modeling uterus made of perspective elastic materials. Real-time operation pictures are shot by the camera, and the pictures of a stretching opening are shot through the picture processing technology and processed to calculate the opening value of the stretching opening. The teaching model and the operation method have the advantages of being complete in structure, high in maneuverability and visible in operation process.

Description

technical field [0001] The invention relates to the technical field of teaching models in medicine, in particular to a teaching model used for skill training in labor process observation and an operation method thereof. Background technique [0002] The abnormally high cesarean section rate in my country has attracted the attention of the World Health Organization. To achieve the goal of reducing the rate of cesarean section and promoting natural childbirth, it is necessary to improve the ability of midwifery professionals to observe the labor process, and to observe the labor process must have the anal examination and vaginal examination technology during the labor process. In the past, the mastery of this skill required a long period of practice and exploration on the puerpera. However, with the enhancement of the self-protection awareness of the puerpera, the clinical teachers did not dare to let go, and the opportunities for students to perform clinical operations were g...

AI Technical Summary

Problems solved by technology

Both vaginal examination and anal examination can be performed, and the data of pelvic cavity size, cervix dilation and fetal head descent can be obtained in the same model, but the operation of this model is carried out under non-direct vision

[0004] The operation under non-direct vision will lead to the following problems: First, when the teacher puts his finger into the vagina or rectum of the model during the training and teaching, the students cannot know how the teacher operates, so it is often necessary to Disassemble and decompose the model into different parts, and change the operation under direct vision into operation under direct vision, so that students can understand, but the simulation effect is very poor; second, when students practice, students put their fingers into the vagina Or after the rectum, the teacher can't know whether the students' operation is correct outside the model, which is not good for training and guiding students; third, after the students give conclusions during the skill operation assessment, the teacher must touch the model again to verify their conclusions. Increased the difficulty and time of the assessment

Fourth, due to the operation under direct vision, the differences in the operating experience of the assessment teachers and the limited number of personnel have a certain impact on the fairness of the assessment results

Although this model is helpful to understand the principles of childbirth, it can hardly provide any training in the observation of the labor process, and it can also mislead students, because this model has three defects: (1) This model has no pelvic structure, no ischial spine, and cannot be trained Judging the position of the fetal head in the pelvis; (2) Although this model has a large model of cervix dilation, the simulation of the degree of dilation of the cervix is ​​too poor for training; (3) The operation check is carried out under non-direct vision

[0007] 2. The Birth Station Simulator produced and sold by Canadian buyamag company is used to examine the relationship between the fetal head and the ischial spine through the vagina, but the model has the following disadvantages: (1) Due to the closed nature of the model, the operation inspection is performed under non-direct vision As a result, the teacher does not know whether the students' operation and inspection methods are correct. (2) This model cannot be used for cervical dilation inspection training

[0008] 3. The Fetal Monitoring And Labor Progress produced and sold by Canadian buyamag company is used to check the degree of dilation of the cervix through the vagina, but it only has three specifications of 1cm, 4cm, and 8cm. There is no pelvic structure, the fetal head cannot be judged, the appearance is not realistic, and the operation is also performed under non-direct vision

[0009] 4. Cervix Vaginal Dilation Module: Assessing Cervical Dilation produced and sold by Canadian buyamag company, this model can only check the dilation of the cervix through the vagina, without ischial spines, and the judgment of the decline of the presenting is based on the distance between the cervix and the vagina, which is easy to mislead students. And the operation is also carried out under non-direct vision

[0010] The above-mentioned models are all operated under non-direct vision, which brings a lot of trouble to the teaching, and their structure is not realistic, which is easy to mislead the students, so that the students cannot fully master the required skills. Therefore, we There is an urgent need to study a visual simulation training model for observation of the labor process
