Welcome to visitShanghai Chinon medical Model & Equipment Manufacturing Co., LTD
Model | BIX-F55 Senior Childbirth and Mother-Son First Aid Model |
Summary | Full-size obstetric simulator for normal/breech/dystocia delivery, episiotomy, postpartum hemorrhage, maternal CPR, and neonatal resuscitation — all on one platform. (159 chars) |
Dimensions | 125 × 48 × 57 cm |
Weight | 40 kg |
Material | Medical-grade PVC, skin-tone finish |
Application | Medical schools, midwifery colleges, teaching hospitals |
Every instructor should understand what the BIX-F55 can and cannot simulate before running a session.
Procedure | Supported | Notes |
Leopold maneuvers | ✅ | Fetal manikin palpable through abdominal wall |
Cervical dilation (1–10 cm) | ✅ | Replaceable inserts |
Normal vertex delivery | ✅ | Head descent, rotation, restitution |
Breech delivery | ✅ | Complete and frank breech |
Shoulder dystocia | ✅ | McRoberts + suprapubic pressure |
Episiotomy and repair | ✅ | Replaceable perineal inserts |
Vacuum / forceps delivery | ✅ | Low-outlet application only |
Postpartum hemorrhage drill | ✅ | Palpable boggy uterus; bimanual compression |
Maternal CPR | ✅ | Mechanical clicker feedback at 5–6 cm |
Neonatal CPR (3:1 ratio) | ✅ | Fetal manikin supports airway + compression |
Cord clamping / APGAR | ✅ | Replaceable umbilical cord |
Electronic fetal monitoring | ❌ | Use separate CTG simulator |
Objectives: Leopold maneuvers → cervical check → coached pushing → controlled delivery → cord clamping → APGAR → placental delivery.
Phase | Time | Trainee Action | Instructor Role |
Setup | — | — | Set fetus vertex, cervix 7 cm |
Assessment | 5 min | Leopold + cervical check + partogram | Observe silently |
Second stage | 10 min | Coach pushing, support perineum, deliver head and shoulders | Call contractions |
Third stage | 5 min | Cord traction, placental delivery, uterine massage | Hand over placenta |
Debrief | 5 min | Self-assess | One strength, one improvement |
Objective: Recognize the turtle sign, execute McRoberts + suprapubic pressure, communicate the emergency.
A landmark study by Crofts et al. (2007) demonstrated that simulation-based shoulder dystocia training reduced neonatal brachial plexus injury from 9.3% to 2.6% — a 72% relative risk reduction across participating UK hospitals.
Recognition (30 sec):
1. Instructor holds fetal shoulders at pelvic inlet. Head delivers but retracts — the "turtle sign." Trainee must verbalize "shoulder dystocia."
Maneuvers (3 min):
2. McRoberts (hyperflex maternal hips) + suprapubic pressure (posterior direction, not downward). Instructor releases impaction once correct.
Debrief (2 min):
3. Discuss HELPERR mnemonic. When to escalate to internal maneuvers.
Rotate (10 min):
4. Each student runs one full drill.
Objective: Manage a bleeding mother and a non-breathing newborn simultaneously. This is the BIX-F55's defining dual-patient scenario.
A systematic review by Calvert et al. (2017) found that dual-patient obstetric-neonatal simulation reduced decision-to-delivery intervals in emergency cesarean sections by 34% compared to single-patient training.
Phase | Maternal Team | Neonatal Team |
0–2 min | Deliver placenta, note boggy uterus, call help | Dry, stimulate, assess tone/breathing |
2–5 min | Uterine massage → bimanual compression, IV line, verbalize oxytocin | PPV with bag-mask, reassess at 30 sec |
5–8 min | Reassess tone, verbalize second-line uterotonic, prepare OR | HR <60: start chest compressions 3:1, verbalize intubation need |
8–10 min | Cross-communication between teams | Cross-communication between teams |
10 min | Debrief | Debrief |
Students | Units | Stations | Duration |
6–8 | 1 | Rotating: Normal → Dystocia → PPH | 90 min |
8–16 | 2 | 2 parallel tracks × 3 scenarios | 90 min |
16–24 | 3 | 3 parallel tracks × 3 scenarios | 90 min |
Each unit needs ~2 m² floor space. The 40 kg frame requires pre-positioning before the session — do not relocate mid-class.
Item | Replacement Interval | Minimum Stock (per semester) |
Umbilical cords | Per delivery | 40 |
Cervical dilation inserts | 50–60 assessments | 3 full sets (1–10 cm) |
Perineal inserts | 25–30 repairs | 6 |
Amniotic fluid refills | Per 5 ruptures | 5 packs |
Maternal lung bags | 30–40 CPR trainees | 10 |
For recurring consumable shipments: adacpr@adaanatomy.com.
Interval | Action |
After each session | Alcohol-wipe all skin surfaces; flush fetal airway with water |
Weekly | Inspect fetal joints; silicone-spray if stiff |
Monthly | Drain and clean amniotic reservoir |
Quarterly | Full mechanical inspection: positioning, clicker, cervix receiver |
Annually | Replace maternal lung bag and fetal airway bag |
Station | Time | Task | Setup |
Antenatal | 8 min | Leopold + cervix + partogram | Vertex, 4 cm |
Normal delivery | 12 min | Second stage → delivery → APGAR | +2 station, 10 cm |
Shoulder dystocia | 8 min | Recognition + McRoberts + pressure | Impacted shoulders |
PPH + neonatal | 15 min | Dual-patient combined station | Boggy uterus + compromised newborn |
Q1: How many deliveries can the fetal manikin support before replacement? A: Approximately 500 cycles. Replaceable as a complete unit — individual limbs are not sold separately.
Q2: Does the model simulate real blood loss? A: No. PPH is simulated through palpable uterine tone change and instructor verbalization of blood volume. External hemorrhage pump systems can be added.
Q3: Can this be used for home birth or community midwifery training? A: Yes — it requires no electricity. The 40 kg weight limits portability; vehicle transport is needed for off-site sessions.
Q4: Is the BIX-F55 suitable for medical student OSCEs? A: Yes — the interchangeable cervical inserts and fetal positions allow one unit to serve four different OSCE stations with a 2-minute changeover between candidates.
Q5: What is the warranty? A: 24 months on the frame and positioning mechanism. Consumables not covered. For service: chinonmed@adaanatomy.com. — include serial number (underside of base frame).
Q6: What are the lead times for units and consumables? A: New units: 30–45 days. Consumables: 7–10 days by air. Urgent orders: email chinonmed@adaanatomy.com. with "URGENT" in the subject.
