Abstract

Abstract Disclosed is an episiotomy trauma repair teaching aid having a plurality of modules each of which incorporates one or more three-dimensional simulated perinea into which various types of surgical incisions used in obstetrics for delivery of babies have been formed. Each module has a layer of resilient molded material to simulate flesh and a colored layer of reinforced, self-sealing membrane to simulate sub-cutaneous tissue.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 204 words
An episiotomy trauma repair teaching aid having a plurality of three-dimensional, simulated perinea modules into which various types of surgical incisions used in obstetrics for delivery of babies have been formed, each of said modules comprising: a firm PCB base; firm PCB sides connected to said base which, with said base, provide rigidity to said module; a foam rubber interior portion having an inner surface and an outer surface, said inner surface affixed to said base, and which simulates the response of flesh to suturing; a plurality of thin layers of elastic polymeric material connected to said outer surface of said interior layer; a plurality of relatively soft colored layers of PCB covering said thin layers of elastic polymeric material, wherein the combination of said layers of elastic polymeric material, said layers of PCB simulates the response of subcutaneous tissue to suturing; and a plurality of resilient and pre-tensioned cords embedded in said interior portion to simulate pelvic musclature, wherein said PCB base, said PCB sides, said foam rubber interior portion, said elastic polymeric material, said relatively soft layers of PCB and said plurality of pre-tensioned cords combine to form a durable, flexible, sewable and realistic module in said episiotomy trauma repair teaching aid.
Claim 2
Dependent Claim 204 words
An episiotomy trauma repair teaching aid having a plurality of three-dimensional, simulated perinea modules into which various types of surgical incisions used in obstetrics for delivery of babies have been formed, each of said modules comprising: a firm PCB base; firm PCB sides connected to said base which, with said base, provide rigidity to said module; a foam rubber interior portion having an inner surface and an outer surface, said inner surface affixed to said base, and which simulates the response of flesh to suturing; a plurality of thin layers of elastic polymeric material connected to said outer surface of said interior layer; a plurality of relatively soft colored layers of PCB covering said thin layers of elastic polymeric material, wherein the combination of said layers of elastic polymeric material, said layers of PCB simulates the response of subcutaneous tissue to suturing; and a plurality of resilient and pre-tensioned cords embedded in said interior portion to simulate pelvic musclature, wherein said PCB base, said PCB sides, said foam rubber interior portion, said elastic polymeric material, said relatively soft layers of PCB and said plurality of pre-tensioned cords combine to form a durable, flexible, sewable and realistic module in said episiotomy trauma repair teaching aid.
Claim 3
Dependent Claim 20 words
An episiotomy trauma repair teaching aid as described in claim 1 wherein said teaching aid comprises six simulated perinea modules.
