Fetal sonography model apparatuses and methods
This disclosure includes embodiments of apparatuses and methods for simulating the uterus of a human (e.g., for training medical providers to perform sonograms, amniocentesis, ultrasound-guided amniocentesis, and/or other procedures). For example, in at least some embodiments, the apparatus comprises a container with a compartment and an anterior wall that is configured to permit sonogram imaging of the compartment. In some embodiments, the apparatus comprises a container that is configured to be removably coupled to the abdomen of a live human or human model such that the compartment simulates the uterus of the human or model.
1. An apparatus comprising:
a container having an anterior wall, a posterior wall, and an internal compartment;
a human fetus model disposed in the compartment; and
a liquid disposed in the compartment;
where the anterior wall is configured to permit sonogram imaging of the human fetus model through the anterior wall; and
where the container is configured to be removably coupled to the abdomen of a live human or human model such that the compartment simulates the uterus of the human or model.
2. The apparatus of claim 1 , further comprising:
a placenta model disposed in the compartment.
3. The apparatus of claim 2 , further comprising:
an umbilical cord model coupled to and extending between the human fetus model and the placenta model.
4. An apparatus comprising:
a container having an anterior wall, a posterior wall, and an internal compartment configured to receive a human fetus model and a liquid;
where the anterior wall is configured to permit sonogram imaging of the compartment through the anterior wall; and
where the container is configured to be removably coupled to the abdomen of a live human or human model such that the compartment simulates the uterus of the human or model.
5. The apparatus of claim 4 , further comprising a human fetus model configured to be disposed in the compartment of the container such that the human fetus model can be imaged through the anterior wall by sonogram.
6. The apparatus of claim 5 , further comprising a liquid configured to be disposed in the compartment of the container with the human fetus model such that the fetus can be imaged through the anterior wall by sonogram.
7. The apparatus of claim 4 , further comprising:
a placenta model configured to be disposed in the compartment of the container such that the placenta model can be imaged through the anterior wall by sonogram.
8. The apparatus of claim 7 , further comprising:
an umbilical cord model coupled to and extending between the human fetus model and the placenta model.
9. The apparatus of claim 1 , where the container comprises an access point through which liquid can be removed from or introduced into the compartment.
10. The apparatus of claim 9 , where the access point is configured such that a human fetus model can be removed from or introduced into the compartment.
11. The apparatus of claim 5 , where the human fetus model comprises a hydraulic heart model, and the apparatus further comprises:
a pump configured to be coupled to the heart model to simulate a heartbeat by pumping liquid to the heart model.
12. The apparatus of claim 5 , where the human fetus model comprises:
a skull model; and
a brain model disposed in the skull, the brain model configured to be distinguishable from the skull model in a sonogram image.
13. The apparatus of claim 5 , where the human fetus model comprises:
one or more bone models disposed in the human fetus model, the one or more bone models configured to be distinguishable from other parts of the human fetus model in a sonogram image.
14. The apparatus of claim 4 , where the anterior wall has a flexible outer surface.
15. The apparatus of claim 14 , where the anterior wall comprises silicone.
16. The apparatus of claim 15 , where the posterior wall comprises silicone.
17. The apparatus of claim 14 , where the anterior wall is configured to be punctured by a needle, and to substantially self-seal the puncture after removal of the needle.
18. The apparatus of claim 17 , where the posterior wall is configured to resist being punctured by a needle.
19. The apparatus of claim 4 , where the anterior wall is unitary with the posterior wall.
20. A kit comprising:
an apparatus of claim 5 ; and
a second human fetus model.
21. The kit of claim 20 , where the second human fetus model is configured to represent a different stage of fetal development than the first human fetus model.
22. A method comprising:
generating one or more images of the compartment of an apparatus using a sonogram machine;
where the apparatus comprises:
a container having an anterior wall, a posterior wall, and an internal compartment;
a human fetus model disposed in the compartment; and
a liquid disposed in the compartment;
where the anterior wall is configured to permit sonogram imaging of the human fetus model through the anterior wall; and
where the container is configured to be removably coupled to the abdomen of a live human or human model such that the compartment simulates the uterus of the human or model.
23. The method of claim 22 , further comprising:
disposing the apparatus on the abdomen of a live human or human model such that the compartment simulates the uterus of the human or model.
