Abstract

Devices, systems, and methods appropriate for use in medical training that include materials that better mimic natural human tissue are disclosed. In one aspect, multi-layer tissue simulations are provided. In another aspect, male genitalia models are provided. In another aspect, abdominal surgical wall inserts are provided. Systems and methods associated with these devices are also provided.

First claim

What is claimed is:

1. A patient simulator, comprising:
a male genitalia model, comprising:
a first layer comprising a simulated scrotum and a simulated penis, wherein the simulated scrotum defines a simulated scrotal cavity;
a second layer comprising a support layer connected to the simulated scrotum to encapsulate the simulated scrotal cavity; and
one or more simulated testes positioned to move freely within the simulated scrotal cavity;

wherein the simulated penis is connected to the support layer, the simulated scrotum, or both.

2. The patient simulator of claim 1 , wherein the male genitalia model further comprises one or more simulated tumors embedded in at least one of the one or more simulated testes for the training of a testicle palpation procedure.

3. The patient simulator of claim 1 , wherein the male genitalia model further comprises a simulated Vas Deferens connected to the one or more simulated testes for the training of a no-scalpel vasectomy procedure.

4. The patient simulator of claim 1 , wherein the male genitalia model further comprises:
a simulated glans; and
a simulated foreskin covering the simulated glans for the training of a circumcision procedure, the simulated foreskin being retractable to expose the simulated glans.

5. The patient simulator of claim 1 , further comprising a manikin to which the male genitalia model is adapted to be detachably connected.

6. The patient simulator of claim 5 , wherein the male genitalia model is adapted to be detachably connected to the manikin via the support layer.

7. The patient simulator of claim 5 , wherein the male genitalia model further comprises a simulated urethra extending through the simulated penis and the support layer for the training of a catheterization procedure.

8. The patient simulator of claim 7 , wherein the manikin comprises a urethra inlet.

9. The patient simulator of claim 8 , wherein, when the male genitalia model is detachably connected to the manikin, the urethra inlet is accessible via the simulated urethra during the training of the catheterization procedure.

10. The patient simulator of claim 8 , further comprising tubing connecting the simulated urethra to the urethra inlet when the male genitalia model is detachably connected to the manikin.

11. The patient simulator of claim 1 , wherein the male genitalia model further comprises a third layer at least partially surrounding the one or more simulated testes within the simulated scrotal cavity.

12. A method, comprising:
forming a simulated scrotum and a simulated penis via a first pour, wherein the simulated scrotum defines a simulated scrotal cavity;
positioning one or more simulated testes within the simulated scrotal cavity such that the one or more simulated testes move freely within the simulated scrotal cavity; and
forming, after the first pour has at least partially cured, a support layer encapsulating the simulated scrotal cavity via a second pour, wherein:
the support layer is connected to the simulated scrotum;
the simulated penis is connected to the support layer, the simulated scrotum, or both; and
the simulated scrotum, the simulated penis, the one or more simulated testes, and the support layer, in combination, form a male genitalia model.

13. The method of claim 12 , further comprising:
embedding one or more simulated tumors in at least one of the one or more simulated testes for the training of a testicle palpation procedure.

14. The method of claim 12 , further comprising:
connecting a simulated Vas Deferens to the one or more simulated testes for the training of a no-scalpel vasectomy procedure.

15. The method of claim 12 ,
wherein the male genitalia model further comprises a simulated glans; and
wherein the method comprises covering the simulated glans with a simulated foreskin for the training of a circumcision procedure, the simulated foreskin being retractable to expose the simulated glans.

16. The method of claim 12 , further comprising detachably connecting the male genitalia model to a manikin.

17. The method of claim 16 , wherein the male genitalia model is detachably connected to the manikin via the support layer.

18. The method of claim 16 , wherein the male genitalia model further comprises a simulated urethra extending through the simulated penis and the support layer for the training of a catheterization procedure.

19. The method of claim 18 , wherein the manikin comprises a urethra inlet.

20. The method of claim 19 , further comprising:
while the male genitalia model is detachably connected to the manikin, accessing the urethra inlet via the simulated urethra during the training of the catheterization procedure.

21. The method of claim 19 , wherein detachably connecting the male genitalia model to the manikin comprises connecting tubing between the simulated urethra and the urethra inlet.

22. The method of claim 12 , further comprising:
at least partially surrounding the one or more simulated testes by a third pour, into the simulated scrotal cavity, after the first pour has at least partially cured.
