BIX-F21 Wearable Gravida Simulator: A Practical Guide to Prenatal Examination Training

Short answer: BIX-F21 is a wearable gravida simulator. A 13 kg abdominal weight reproduces the weight of a 40-week pregnancy, and the apparent stage of pregnancy can be changed by adjusting the liquid volume in the uterine cavity. Because the learner wears it instead of looking at it, the simulator adds the part no bench model can give — the student's own body position, balance and fatigue while performing Leopold manoeuvres, breast nursing and other prenatal diagnostics.

Key takeaways

• Adjustable gestation. 13 kg of abdominal weight models 40 weeks; other weeks are set by adjusting the liquid in the uterine cavity.
• Measurable landmarks. Injecting warm water into the uterus simulates amniotic fluid and allows uterine height and abdominal circumference to be measured.
• Wearable by design. Suitable for practice by male adults, unmarried women, students and premarital education groups.
• Runs the procedures. Supports Leopold manoeuvres, breast nursing and other prenatal diagnosis, plus simulated amniotic-fluid sampling windows (8–10 weeks) and amniotomy windows (16–20 weeks).
• Empathy is a training objective. The wearer can experience chest distress, lumbago and urinary frequency caused by the enlarged uterus, along with the general inconvenience of pregnancy.

What the simulator can actually run

Why "wearable" changes the skill you are teaching

On a bench model, the learner controls the object: it can be rotated, tilted and re-examined until the answer appears. In a real prenatal examination the patient sets the conditions — she is lying down, she is uncomfortable, and the examiner has to work around her. A wearable simulator restores that asymmetry, which is why it is useful for the same reason simulation generally is: repeated deliberate practice under realistic constraints produces skills that transfer to the clinical setting [1].

It also makes the training two-sided. Because the published specification includes the physiological states the wearer feels — chest distress, lumbago, urinary frequency — the student wearing the unit gets the patient's side of the consultation, not only the examiner's. Dedicated prenatal care remains one of the highest-leverage points in obstetric outcomes, so practising how the assessment is delivered, and not only how it is measured, is worth the station time [2].

Six-step station setup

1. Fit the unit. Have the "patient" put the wearable on over light clothing and stand to check balance and weight distribution before lying down.
2. Set the gestational stage. Adjust the liquid in the uterine cavity to the stage you want assessed; record the setting so the examiner's answer can be scored against it.
3. Add the fluid. Inject warm water into the uterus to simulate amniotic fluid — this is what makes fundal height and abdominal circumference measurable.
4. Run the four Leopold manoeuvres. Time the sequence and ask the examiner to state lie, presentation and position out loud.
5. Measure and record. Take uterine height and abdominal circumference with a tape; repeat at a different setting to test consistency.
6. Debrief both roles. Ask the wearer to describe what the examination felt like and the examiner to justify each hand placement.

Before you order: four things to confirm

• Gross weight and carton quantity. Neither is published; both matter if the unit will be shipped or stored with other lab equipment.
• Liquid handling. Ask what volume of water the uterine cavity takes and how it is drained and dried between sessions.
• Hygiene routine. Confirm the cleaning method for the abdominal surface, since it is worn against the body.
• Class size. Decide how many units you need if several students must wear it in a single session.

FAQ

Q1. What is BIX-F21?
It is a wearable gravida simulator used for prenatal examination training; the weight and shape of pregnancy are carried by the wearer rather than presented on a table.

Q2. How is the stage of pregnancy changed?
A 13 kg abdominal weight reproduces 40 weeks of pregnancy, and different weeks can be simulated by adjusting the liquid in the uterine cavity.

Q3. Can fundal height and abdominal circumference really be measured?
Yes. Warm water is injected into the uterus to simulate amniotic fluid, and uterine height and abdominal circumference can then be measured.

Q4. Which procedures are supported?
Leopold manoeuvres, breast nursing and other prenatal diagnosis, plus simulated amniotic-fluid sampling at 8–10 weeks and amniotomy at 16–20 weeks.

Q5. Who can wear it?
The specification lists male adults, unmarried women, students and premarital education groups — the unit is designed for mixed teaching cohorts.

Q6. How do I get the price, carton quantity and gross weight?
Email sophia@adahealthy.com with the model (BIX-F21), the number of units and your destination port; the sales team will send the quotation and the packing data.
