Referring to fig. 1, the embodiment of the present invention provides an artificial rupture of membranes teaching aid, which mainly comprises a uterus model 10, an amniotic bag 40, a fetus model 50, a perineum model 20 and a cervical orifice model 30. Wherein, the uterus model 10 is internally provided with an accommodating cavity 13, an inflation cavity 14 is formed inside the uterus wall of the uterus model 10, and the outer side of the uterus wall is provided with an air inlet pipe 11 and an air outlet pipe 12 which are communicated with the inflation cavity 14. In order to realize the inflation of the inflation cavity 14, the artificial rupture of membranes teaching aid further comprises an inflator pump, and the inflator pump is communicated with the air inlet pipe 11. Meanwhile, in order to conveniently realize the control of air inlet and air outlet, switch valves are arranged in the air inlet pipe 11 and the air outlet pipe 12, and the free switching of the two states of air inflation and air deflation of the air inflation cavity 14 can be realized by controlling the on-off of the two switch valves and the working state of the air inflation pump.
The amniotic membrane bag 40 is arranged in the accommodating cavity 13, the amniotic membrane bag 40 is internally provided with a amniotic fluid cavity, the top of the amniotic fluid cavity is provided with a bag opening 43 which can be opened and tightened, a placenta attachment part is arranged on the inner side wall of the amniotic fluid cavity, the placenta attachment part is connected with a placenta model 61, an umbilical cord 60 is connected onto the placenta model 61, and an adding hole communicated with the amniotic fluid cavity is formed in the amniotic membrane bag 40. The fetal model 50 is loaded into the amniotic chamber through the mouth 43 and the other end of the umbilical cord 60 is connected to the fetal model 50 and amniotic fluid is added to the amniotic chamber through the addition port.
It should be understood that in order to facilitate placement of the amniotic bag 40 containing the fetal model 50 into the receiving cavity 13 of the uterine model 10, the uterine model 10 may be configured to be deflated with a larger opening at the bottom to facilitate placement of the amniotic bag 40. When the uterus model 10 is inflated, the opening at the bottom of the uterus model 10 is continuously narrowed, and finally, the opening is shrunk to just fit the perineum model 20 and the cervical orifice model 30. And the inner side of the uterine wall of the uterine model 10 is continuously contracted to apply pressure to the amniotic bag 40.
The perineum model 20 is arranged at the opening at the bottom of the uterus model 10; the cervical orifice model 30 is positioned between the perineum model 20 and the amniotic bag 40 and is connected to the bottom of the amniotic bag 40, the perineum model 20 is communicated with the cervical orifice of the cervical orifice model 30, and an operator can conveniently stretch fingers into the bottom of the amniotic bag 40 and probe the fingers.
Amniotic fluid is filled in the amniotic bag 40 of the artificial rupture of membranes teaching aid, the inflatable cavity 14 is inflated through the air inlet pipe 11, and the inflatable cavity 14 is deflated through the exhaust pipe 12, so that intermittent uterine contraction can be simulated. Specifically, when the inflation cavity 14 is inflated, the inner side of the uterine wall inwardly presses the amniotic membrane bag 40, and pressure is formed on the amniotic membrane bag 40, so that the front end part of the amniotic membrane bag 40 is inflated, and the state of uterine contraction is simulated; when the inflation cavity 14 is deflated, the amniotic bag 40 is restored to a state of low tension, simulating the end of the uterine contraction or the interval period of the uterine contraction.
The operator can enter from the vaginal opening of the perineum model 20 to touch the cervical opening to know the opening condition of the cervical opening, and can touch the amniotic membrane bag 40 from the cervical opening with the index finger and the middle finger and feel the pressure of the amniotic membrane bag 40 and whether the uterine contraction exists, and can also know the condition of fetal presenting. The amniotic membrane bag 40 is broken by tissue forceps during the uterine contraction intermission period, and the properties and the amount of the effused amniotic fluid are observed. Through many times of practice and observation, the manual rupture experience of the operator can be accumulated.
In order to conveniently simulate the opening size of the cervical orifice model 30, the cervical orifice of the cervical orifice model 30 is set to have different sizes, and the specific diameter size of the diameter of the cervical orifice can be 0-10 cm. The cervical orifice model 30 is fixed at the bottom of the amniotic bag 40 in a sticking way, so that different specifications and sizes can be conveniently replaced.
In some of these embodiments, the addition holes include a water injection hole 41 and a feed hole 42. Since amniotic fluid is generally prepared from water and an aqueous sample substance, water may be added through the water injection hole 41 and a solid aqueous sample substance may be added through the feed hole 42.
It should be understood that the addition hole can be only one, and at this time, the amniotic fluid is prepared first and then injected into the amniotic cavity through the only addition hole.
In order to simulate different situations of the amniotic fluid flowing out after artificial membrane rupture, the amniotic fluid is divided into a plurality of grades, and each grade is distinguished according to different colors and the existence of solid matters. By controlling the component ratio of the water and the amniotic fluid component sample substances, the classification of grades can be completed, and the classification specifically comprises the following steps: the number of the sheep bodies is four grades, namely, clear water, I degrees (the amniotic fluid is light yellow or light green and has no solid or meconium-like substances), II degrees (the amniotic fluid is light yellow or light green and is turbid and has partial solid or meconium-like substances), and III degrees (the amniotic fluid is green or dark green and is viscous and has a large amount of meconium-like substances).
In the specific teaching process, the fetal model 50 is firstly put into the amniotic membrane bag 40 from the bag opening 43, water is respectively added from the water injection holes 41, the amniotic fluid sample substance is added into the amniotic membrane bag 40 from the feeding hole 42, the fetal model 50 is pushed down from the bag opening 43 to form a front amniotic membrane sac, and the bag opening 43 is tightened. The cervical orifice model 30 is then adhered to the underside of the anterior amniotic sac. The assembled whole set of model is placed in the uterus model 10, and the perineum model 20 is arranged at the bottom opening of the uterus model 10.
During teaching, an operator can touch the cervical orifice with the index finger and the middle finger from the vaginal orifice of the perineum model 20 and touch the anterior amniotic sac upwards through the cervical orifice, so that the operator can touch the anterior amniotic sac and feel the tension of the anterior amniotic sac and the fetal exposure.
When the model is in the uterine contraction intermission period, the front amniotic sac forceps can be broken by using the tissue forceps, at the moment, amniotic fluid flows out from the vaginal orifice, and an operator observes the amniotic fluid property and makes a judgment on the amniotic fluid property. When the training needs to be carried out again, the training can be carried out again only by replacing the amniotic membrane bag 40 and re-injecting amniotic fluid.
By using the artificial rupture of membranes teaching aid, an operator can be trained to judge and select different operation methods according to the orientation of the fetus, the position of the fetus exposed before the fetus and the situation of uterine contraction in specific operation.
