Description
Technical Field
The utility model relates to the field of medical instruments, in particular to a vaginal examination teaching aid for evaluating the progress of labor.
Background
Normal delivery is the physiological process of spontaneous delivery of a fetus from the maternal birth canal, and how to accurately assess the progress of the delivery process (i.e., the progress of labor) is the key to predicting the outcome of delivery and preventing dystocia. Clinically, the indicators for evaluating the progress of labor include four indicators, such as frequency and intensity of uterine contraction (abbreviated as "uterine contraction"), dilation size of cervical orifice (abbreviated as "uterine orifice dilation"), a descending level of fetal head in the cavity of mother pelvis (abbreviated as "fetal head descending"), and a rotational orientation of fetal head relative to mother pelvis (abbreviated as "fetal orientation"). The uterine contraction can be evaluated by arranging the electronic fetal heart monitor on the abdomen of the mother body, the operation is simple and convenient, and the result is objective and reliable. However, the three indexes of the expansion of the uterine orifice, the descending of the fetal head and the orientation of the fetus cannot be monitored visually, and can be evaluated indirectly only by the vaginal examination performed by an obstetrician or a midwife. Moreover, the accuracy of such evaluations is continually increasing through repeated, multiple manipulations and experiences. However, in practice, vaginal examinations need to take account of the privacy protection of the parturient, and many times of vaginal examinations also increase the discomfort of the parturient and the risk of infection of the birth canal, so that both the number and the number of examinations are clearly regulated and strictly limited. Therefore, for beginners of obstetrics or midwifery specialties, such as interns/midwives, low-age hospitalization doctors/midwives, there are few opportunities to perform vaginal examinations during childbirth of a parturient, and thus it is not easy to grasp the method and skill for evaluating the progress of labor, resulting in slow growth rate and prolonged culture period. Therefore, the design of the vaginal examination teaching aid for evaluating the labor progress has very important significance for clinical teaching, training and examination of obstetrics.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a vaginal examination teaching aid for evaluating the progress of labor process, and provides a learning way for beginners to learn obstetrical knowledge by simulating the uterus, vagina, ischium and pubis of a lying-in woman.
In order to realize the purpose of the utility model, the utility model adopts the following technical scheme: a vagina examination teaching aid for assessing labor progress comprises a uterus simulation device and a baby skull simulation device, wherein the baby skull simulation device is placed in the uterus simulation device, the uterus simulation device comprises a fixing frame for simulating female bones and a tissue-like body for simulating human tissues, the tissue-like body comprises a first silica gel body for simulating a female uterus and a first silica gel tube for simulating a vagina, the fixing frame comprises a first support for simulating human ischium and a second support for simulating human pubis, a notch is formed in the first silica gel body and used for simulating a human uterus mouth, the notch faces the first silica gel tube in a positive direction, the first silica gel tube is detachably connected with the first silica gel body, an opening is formed in one end, far away from the first silica gel tube, of the first silica gel body, and the opening is used for the baby skull simulation device to enter; the infant skull simulation device comprises a skull mold for simulating the skull of an infant, one end of the skull mold is connected with a control assembly for controlling the skull mold, and the skull mold can be plugged into the first silica gel body; the arrangement of the uterus simulating device and the arrangement of the infant skull simulating device both correspond to female human tissues.
Preferably, the control assembly comprises a fixed rod, and a hand-held handle is arranged at the rear end of the fixed rod.
Preferably, the skull mould is provided with a groove at one end away from the control assembly, and the groove is used for simulating the seam, the halogen door and the radial line of the skull of the fetal head of the infant.
Preferably, the tissue-like bodies are made of transparent silica gel.
Preferably, a protrusion is arranged on one side opposite to the middle part of the first support, and the protrusion is used for simulating ischial spines.
Compared with the prior art, the vaginal examination teaching aid for evaluating the labor progress has the following beneficial effects:
the accessibility of labor teaching is improved: the vaginal examination teaching aid can provide more convenient ways and more training opportunities for beginners in obstetrics or obstetrics professionals to learn the progress of the labor, and helps the beginners to learn to feel and accumulate experience through repeated practice on the teaching aid model, so that the operation method and skill for vaginal examination and assessment of the progress of the labor can be mastered in a shorter time.
Secondly, improving the accuracy of labor assessment: since the assessment of labor progress depends on subjective feeling and empirical judgment of the examiner, the assessment results are not free from errors. The vaginal examination teaching aid can set parameters of the labor progress index, such as the size of the expansion of the uterine orifice, and help learners compare and correct self-examination results with the set parameters in repeated practice, so that the accuracy of subjective judgment is improved.
Thirdly, improving the consistency of the labor process assessment: the subjectivity of the labor progress assessment determines that the assessment results of different inspectors may be different, so that the subsequent treatment measures are different. The vaginal examination teaching aid can set parameters of labor progress indexes and help different learners establish the same or very similar subjective feelings on the same index parameters in repeated practice, so that the consistency of evaluation results is improved.
Fourthly, reducing the incidence rate of head dystocia: in the difficult production of the head, the abnormal tire orientation is not found in time in a part of reasons. The skull mold is placed in the vaginal examination teaching aid, is similar to the skull of a fetus and has skeleton lines such as gullies and the like (used for simulating skull seams and fontanels of the fetus), so that a learner can be helped to master a fetus orientation evaluation method, abnormal fetus orientations can be found and adjusted in time by taking measures, and the occurrence of head dystocia is reduced.
And fifthly, the satisfaction degree of parturient delivery is improved: the vaginal examination teaching aid can help beginners in obstetrics or obstetrics to improve labor progress evaluation skills through simulation practice, so that the possibility that puerperae are used as practice training objects can be reduced. The puerpera may obtain more privacy protection in the process of delivery, the discomfort can be reduced and the infection risk of the birth canal can be reduced due to the limitation of the number of times of detection, and the delivery experience can be improved.
Sixthly, the training and assessment method can be used for skill training and assessment: the whole uterus simulator adopts transparent silica gel/rubber material at present, except that the simulation women skin and tissue, transparent material can let the better observation and study of learner, can cover materials such as drape during the test and shield, better simulation human test effect. Therefore, the vaginal examination teaching aid can be used for obstetrical clinical skill training and examination in medical colleges and universities or midwifery medical institutions.
