Teaching with real people is accurate, but limited; teaching with oral instructions and hanging pictures can only understand the four-step palpation method in theory, and cannot be actually operated, so the teaching effect is limited. Based on this, using the pregnant woman's four-step palpation teaching model for four-step palpation teaching is a better choice.

[0027] Embodiment 1

[0028] This embodiment provides an automatic filling device for a pregnant woman four-step palpation teaching model. Figure 1 As shown, the teaching model includes an abdominal cavity 10 formed by an abdominal skin component and a pregnant woman model base, a uterus 20 located in the abdominal cavity 10, and a fetus 30 located in the uterus 20. This embodiment is described by taking a fetus 30 as an example, and the fetus 30 is immersed in the liquid of the uterus 20 to simulate the fetus 30 being located in the amniotic fluid.

[0029] In a preferred embodiment, the automatic filling device includes a first circulation pipeline 40 connected to the fetus 30, and the first circulation pipeline 40 is provided with a first filling pump group 41, a fluid source 42, and a first flow meter 43 for measuring the amount of fluid injected into the fetus 30. The first filling pump group 41 can inject the fluid in the fluid source 42 into the fetus 30, and extract the fluid from the fetus 30 into the fluid source 42. The fluid source 42 is gas or liquid. When the fluid source 42 is gas, such as compressed air, the inlet of the first filling pump 411 is connected to the outside atmosphere, and the outlet of the first extraction pump 412 is connected to the outside atmosphere; when the fluid source 42 is liquid, the inlet of the first filling pump 411 is connected to a liquid storage tank containing liquid, and the outlet of the first extraction pump 412 is connected to the liquid storage tank.

[0030] With this technical solution, the first filling pump group 41 works (specifically, the first filling pump group 41 can be operated manually, or the first filling pump group 41 can be controlled by a controller) to inject the fluid into the fetus 30 through the first circulation pipeline 40, and the volume of the fetus 30 increases. The first flow meter 43 measures the amount of fluid injected into the fetus 30. For example, a flow meter used to measure the amount of gas at a gas station can be used to measure the amount of fluid at one time. Since the size of the fetus 30 is different at different gestational weeks, the amount of fluid injected corresponds to the size of the fetus 30. Therefore, by controlling the amount of fluid injected into the fetus 30, the size of the fetus 30 at different gestational weeks can be simulated to facilitate palpation teaching.

[0031] After the palpation teaching is completed, the first filling pump group 41 works to completely extract the liquid in the fetus 30 through the first circulation pipeline 40 to facilitate the next palpation teaching.

[0032] In this embodiment, the first circulation pipeline 40 includes a first filling pipe 401 connected to the filling port of the fetus 30, and a first extraction pipe 402 connected to the extraction port of the fetus 30, and the first flow meter 43 is installed on the first filling pipe 401. The first filling pump group 41 includes a first filling pump 411 connected to the end of the first filling pipe 401 away from the fetus 30, and a first extraction pump 412 connected to the end of the first extraction pipe 402 away from the fetus 30. The inlet of the first filling pump 411 is connected to the fluid source 42, and the outlet of the first extraction pump 412 is connected to the fluid source 42. The first filling pump 411 can inject the fluid in the fluid source 42 into the fetus 30 through the first filling pipe 401, and the first extraction pump 412 can extract the fluid from the fetus 30 to the fluid source 42 through the first extraction pipe 402. The first filling pump 411 and the first extraction pump 412 are manually controlled manual pumps; or the first filling pump 411 and the first extraction pump 412 may be controlled to work by a controller described below.

[0033] In another preferred embodiment, the automatic filling device also includes a controller and a manual interaction interface; the controller pre-stores the first fluid injection data corresponding to different gestational weeks, and the first injection control end of the controller is connected to the filling end of the first filling pump group 41, specifically connected to the enable end of the first filling pump 411; the controller is connected to the manual interaction interface, and the manual interaction interface is used to input different gestational weeks.

[0034] When in use, the gestational age of the fetus to be simulated is input in the manual interaction interface, and then the first filling pump 411 is started. The first fluid injection data corresponding to different gestational ages are pre-stored in the controller. The controller includes a first comparator and a memory. The first flow meter 43 detects the injection flow and transmits it to the first input end of the first comparator. The second input end of the first comparator is connected to the first fluid injection data output end of the memory. The output end of the first comparator is connected to the stop end of the first filling pump 411. When the first flow meter 43 detects that the amount of fluid injected into the fetus 30 reaches the preset value (first fluid injection data), the controller controls the first filling pump 411 to stop filling.

[0035] Embodiment 2

[0036] The structural principle of this embodiment is basically the same as that of the first embodiment, except that the number of fetuses 30 in the uterus 20 is two, simulating twins. Figure 2 As shown, in this embodiment, the two fetuses 30 are each connected to a first filling pipe 401 connected to a first filling pump 411, and the two first filling pipes 401 are provided with an injection switching valve 44 and a first flow meter 43, that is, the two fetuses 30 can be filled with fluid respectively; the two fetuses 30 are both connected to the first extraction pipe 402, and after use, the fluid in the two fetuses 30 is extracted by a first extraction pipe 402.

[0037] Since the size of a single fetus 30 of twins at different gestational weeks is different from that of a single fetus, the manual interaction interface can also be used to select whether to input a single fetus or twins. The controller also pre-stores the first fluid injection data corresponding to the different gestational weeks of twins, thereby simulating the different gestational weeks of twins, which is convenient for teaching palpation of twins. When it is necessary to simulate a single fetus, the injection switching valve 44 on one of the first filling pipes 401 is opened, and the injection switching valve 44 on the other first filling pipe 401 is closed, and the first filling pump 411 only fills one of the fetuses 30 with fluid.

[0038] Embodiment 3

[0039] The structural principle of this embodiment is basically the same as that of the first and second embodiments, except that the amount of amniotic fluid in the uterus 20 at different gestational weeks can also be simulated. Figure 3As shown, in this embodiment, the automatic filling device also includes a second circulation pipeline 50 connected to the uterus 20, and the second circulation pipeline 50 is provided with a second filling pump group 51, a liquid storage container 52, and a second flow meter 53 for measuring the amount of liquid injected into the uterus 20. The second filling pump group 51 can inject the liquid in the liquid storage container 52 into the uterus 20, and extract the liquid from the uterus 20 into the liquid storage container 52.

[0040] The second filling pump group 51 works to inject liquid into the amniotic membrane of the uterus 20 through the second circulation pipeline 50 to simulate amniotic fluid, and the second flow meter 53 measures the amount of liquid injected into the uterus 20. Since the amount of amniotic fluid varies at different gestational weeks, the amount of amniotic fluid injected corresponds to the gestational week. Therefore, when simulating different gestational weeks, the corresponding amount of amniotic fluid is injected to facilitate palpation teaching. After the palpation teaching is completed, the second filling pump group 51 works to completely extract the liquid in the uterus 20 through the second circulation pipeline 50 for use in the next palpation teaching.

[0041] In this embodiment, the second circulation pipeline 50 includes a second filling pipe 501 connected to the filling port of the uterus 20, and a second extraction pipe 502 connected to the extraction port of the uterus 20, and the second flow meter 53 is installed on the second filling pipe 501. The second filling pump group 51 includes a second filling pump 511 connected to the end of the second filling pipe 501 away from the uterus 20, and a second extraction pump connected to the end of the second extraction pipe 502 away from the uterus 20, the inlet of the second filling pump 511 is connected to the liquid storage container 52, and the outlet of the second extraction pump is connected to the liquid storage container 52. The second filling pump 511 can inject the fluid in the liquid storage container 52 into the uterus 20 through the second filling pipe 501, and the second extraction pump can extract the fluid from the uterus 20 to the liquid storage container 52 through the second extraction pipe 502.

[0042] In this embodiment, the controller pre-stores second fluid injection data corresponding to different gestational weeks, and the second injection control end of the controller is connected to the filling end of the second filling pump group 51, specifically to the enable end of the second filling pump 511.

[0043] When in use, the gestational age and number of fetuses to be simulated are input in the manual interaction interface, and then the first filling pump 411 and the second filling pump 511 are started. Since the controller pre-stores the first fluid injection data and the second fluid injection data corresponding to different gestational ages,

[0044] The controller includes a first comparator, a second comparator and a memory. The first flow meter 43 detects the injection flow and transmits it to the first input end of the first comparator. The second input end of the first comparator is connected to the first fluid injection data output end of the memory. The output end of the first comparator is connected to the stop end of the first filling pump 411. The second flow meter 53 detects the injection flow and transmits it to the first input end of the second comparator. The second input end of the second comparator is connected to the second fluid injection data output end of the memory. The output end of the second comparator is connected to the stop end of the second filling pump 511. When the first flow meter 43 detects that the amount of fluid injected into the fetus 30 reaches a preset value, the controller controls the first filling pump 411 to stop filling. When the second flow meter 53 detects that the amount of fluid injected into the uterus 20 reaches a preset value, the controller controls the second filling pump 511 to stop filling amniotic fluid.
