BIX-F31 Postpartum Fundus Model: A Three-Station Lesson Plan

Short answer: BIX-F31 is a pelvic model for postpartum uterine fundus assessment and fundal massage. The page lists six interchangeable uteri — normal, first-hour postpartum, second-day postpartum, second-week postpartum, a firm well-contracted uterus and a soft poorly contracted uterus — plus movable hip joints and an accessible vaginal orifice. That set lets a teacher run the same check on six different clinical pictures in one session, which is exactly what involution teaching needs.

Key takeaways

Six uteri, one model: the clinical picture changes by swapping the insert, not by buying another manikin.
Time is built in: first hour, day two and week two let trainees feel how involution actually progresses.
Tone is separable from time: a firm and a soft uterus at the same postpartum stage teach the difference between a normal and an atonic fundus.
Positioning is realistic: movable hips and an expandable vaginal orifice support the actual examination posture.
Packaging is unpublished: carton quantity, size and gross weight all read "not available".

What each uterus insert teaches

Insert	What the trainee should notice
Normal uterus	The baseline: size, consistency and position before pregnancy changes the picture.
Postpartum, first hour	Fundus height and firmness immediately after delivery — the window when most bleeding begins.
Postpartum, day 2	The expected descent; comparing it with the first-hour insert makes involution tangible.
Postpartum, week 2	The later stage, when the fundus is no longer palpable abdominally in many women.
Firm, well-contracted	What a reassuring fundus feels like, and how massage maintains it.
Soft, poorly contracted	The atonic fundus: the finding that triggers massage, uterotonics and escalation.

Three stations, 45 minutes

Station 1 — locate and describe (12 min). With the first-hour uterus in place, each trainee finds the fundus, states its height relative to the umbilicus and describes consistency in two words. No massage yet.
Station 2 — compare across time (15 min). Swap to day 2 and week 2 inserts. Ask the trainee to rank them by height and explain what changed. This is the step that turns a single finding into a trend.
Station 3 — massage on a soft uterus (18 min). Swap to the soft, poorly contracted insert. Trainee performs fundal massage, explains what they are feeling for, and states the escalation threshold out loud.

Run the stations in that order. Starting with the soft uterus teaches panic; starting with the normal one teaches a baseline against which the abnormal becomes obvious.

What the evidence says about postpartum simulation

Postpartum haemorrhage is the reason fundus assessment is drilled, and the simulation literature is unusually practical. A follow-up study of self-perceived long-term transfer after postpartum haemorrhage simulation training found that clinicians retained and used the sequence months later, which supports repeated station practice rather than a single lecture [1]. A 2026 report on how lifelike patient simulators are training US rural care teams describes the same logic in a low-volume setting: the team rehearses the rare emergency so that the first real case is not the first rehearsal [2]. A 2026 survey of postpartum haemorrhage self-efficacy among obstetric providers adds the missing link — confidence tracks recent practice, not years of experience [3].

The limitation is honest: BIX-F31 teaches assessment and massage, not haemorrhage management as a whole. There is no bleeding, no vital-sign change and no team communication built into the model. Use it inside a drill that includes those elements.

FAQ

Q1. What is BIX-F31 used for?
Postpartum uterine fundus assessment and fundal massage training, including palpation of fundal height and consistency.

Q2. How many uterus inserts are included?
Six are listed: normal, first-hour postpartum, day-2 postpartum, week-2 postpartum, a firm well-contracted uterus and a soft poorly contracted uterus.

Q3. Can the model be positioned for a realistic examination?
Yes. The hip joint is movable so the correct body position can be set, and the vaginal orifice expands with the labia minora separable.

Q4. Does it simulate bleeding?
No. The page describes assessment and massage only; postpartum haemorrhage and vital-sign changes are not listed.

Q5. What are the carton details?
Quantity per carton, package size and gross weight are all printed as "not available" and must be requested.

Q6. How do I get a price?
Email sophia@adahealthy.com with the model (BIX-F31), quantity and cohort size. Ask for the insert list and replacement pricing in the same message.
