Duboureau et al. (2021) use its '''shape''': the top of a bottle larger than one litre, inverted and tilted, is the inguinal canal, and the neck below it is the internal inguinal ring. The neck calibre was not incidental — it was chosen because it matched an infant's internal inguinal ring, and the source records that a smaller bottle was tried and rejected because the mouth size did not resemble the infant's anatomy. The Foley Catheter Tamponade Simulator uses its '''volume''': a clean bottle larger than 32 oz is repurposed as the reservoir that collects water returning from the fluid circuit, costed at US$1.50. Both builds rely on the same everyday properties — it is free or near-free, it cuts cleanly with scissors, it is rigid enough to hold an assembly at a fixed angle, and its neck is a ready-made circular aperture of a repeatable size. In the Duboureau build the assembled bottle is kept between learners and only the gloves are replaced, so one bottle serves many sessions.\n| synonyms_text =\n* Common names: Plastic bottle, water bottle, drinks bottle, PET bottle, soda bottle\n* Forms recorded in the builds: bottle larger than one litre, cut into a top funnel and a reserved base; clean bottle larger than 32 oz used whole as a reservoir\n| tissues_rows = \n[[TissueDB/Tissues/Inguinal Canal|Inguinal canal]]\n\n\n[[TissueDB/Simulators/Pediatric Laparoscopic Inguinal Hernia Repair Simulator (Duboureau)|Pediatric Laparoscopic Inguinal Hernia Repair Simulator (Duboureau)]]\nThe top of the bottle, cut 7 cm below the neck, inverted to form a funnel and tilted so that its axis matches the orientation of the inguinal canal relative to the abdominal wall. The source specifies a bottle of volume greater than one litre.\n\n\n[[TissueDB/Tissues/Internal Inguinal Ring|Internal inguinal ring]]\n\n\n[[TissueDB/Simulators/Pediatric Laparoscopic Inguinal Hernia Repair Simulator (Duboureau)|Pediatric Laparoscopic Inguinal Hernia Repair Simulator (Duboureau)]]\nThe neck of the same bottle, with the cap and the plastic ring beneath it removed. The neck calibre was selected because it mimicked the infant's internal inguinal ring; smaller bottles were tested and rejected because the mouth size did not resemble the infant's anatomy. The peritoneum is closed with an intracorporeal knot at this neck.\n\n\n(Structural chassis — holds and mounts the assembly; not a tissue simulant)\n\n\n[[TissueDB/Simulators/Pediatric Laparoscopic Inguinal Hernia Repair Simulator (Duboureau)|Pediatric Laparoscopic Inguinal Hernia Repair Simulator (Duboureau)]]\nThe bottle is cut at two points, 7 cm below the neck and 7 cm from the bottom, and the intermediate cylindrical section is discarded. The reserved base is pierced in the centre and joined to the funnel by an elastic loop knotted around the neck, so the two parts stay together inside the laparoscopic-trainer box, where the assembly is taped at its angle. Model parts are costed at about US$5 in total; no per-item price is given for the bottle.\n\n\n(Structural — fluid reservoir; not a tissue simulant)\n\n\n[[TissueDB/Simulators/Foley Catheter Tamponade Simulator|Foley Catheter Tamponade Simulator]]\nOne plastic water bottle, US$1.50, collecting the water returning from the simulator circuit. The guide suggests a bottle larger than 32 oz and records that a clean bottle can be repurposed. The pump feeds the mechanism and the mechanism drains to this reservoir, completing the circuit.\n\n| accessibility_notes = A repurposed household item in both builds. The Foley guide costs it at US$1.50 and states that a clean used bottle can be repurposed; Duboureau et al. give no per-item price and cost the whole set of model parts at about US$5. The one specification that matters is size: greater than one litre for the Duboureau trainer, where the neck calibre is the anatomical match, and greater than 32 oz for the Foley reservoir, where the volume is the requirement.\n| processing = Cut with scissors. In the Duboureau build the bottle is cut horizontally at two points, the cap and the ring beneath it are removed from the neck, the ring is set aside and reused to hold the folded gloves and elastic loops against the bottle, and a small hole is pierced in the centre of the reserved base. The Foley build uses the bottle whole and unmodified.\n| description = Reused plastic drinks bottle, cut into an inverted funnel and neck that stand in for the inguinal canal and internal inguinal ring, or used whole as a fluid reservoir.\n| references =Duboureau H, Renaud-Petel M, Klein C, Haraux E.
