Nanti, an ergonomic delivery bed engineered for vertical natural childbirth within standard surgical operating rooms, was designed to bridge the gap between maternal birth preferences and hospital safety protocols. Developed as an academic case study at Hospital Country 2000 in Guadalajara, Mexico, the project applies User-Centered Design (UCD) to facilitate vertical delivery without compromising surgical sterility, medical access, or emergency position adjustments.

OVERVIEW
Problem
With a workforce exceeding 200 individuals, including interns, social services, and coordinators from about 10 teams, optimizing tasks, processes, and documents is crucial for ensuring alignment and uniformity, ultimately streamlining operations within the department.
Product Goals:
To engineer a dual-purpose surgical delivery bed compatible with standard operating room protocols and anthropometric measurements of Mexican women aged 25–30.

Research
Research & User Insights
Field research and surveys conducted with 55 multidisciplinary hospital users (gynecologists, nurses, anesthesiologists, pediatricians, and mothers) yielded critical design requirements:
- Delivery Preferences: 66.7% of gynecologists and 50% of nurses preferred stretchers supporting vertical birth postures.
- Automation: 100% of gynecologists and anesthesiologists required automatic adjustment controls for rapid repositioning during surgical emergencies.
- Safety & Comfort: 82.9% of mothers emphasized the need for dynamic, highly adaptable handles, while 60% prioritized modular leg and calf support.

Final Prototypes
…

Base
The base serves as the primary support of the bed, featuring a circular geometry engineered to maintain proper equilibrium against various applied forces.

Waste Container
An independent compartment where delivery waste (primarily fluids) is collected and routed to a rear-mounted receptacle, minimizing direct contact for hospital staff.

Pneumatic Cylinder
A linear actuator mechanism that raises and lowers the lower section of the bed for safety. Utilizing an air-pressure system, it generates sufficient force to support over 136 kg, the minimum requirement for surgical beds.

Pedals
Designed to adjust seat height according to the gynecologist's needs. These are detachable from the base, allowing for customizable positioning distance.

Backrest
An ergonomic support structure for the mother during labor, fitted with a mattress made of a urethane core and Lectrolite for rapid, effective sanitation. It reclines from 0° to 90°.

Leg Rest Assembly
A structural system that accommodates the legs alongside non-slip footrests. It adapts to different body types via a split and expandable mechanism. Length adjustments are secured with a pressure knob, providing optimized thigh and calf support based on user feedback.

Handles
Ring-shaped silhouettes designed to provide lateral stability and security for the mother. They slide linearly along the seat base and rotate around their primary attachment point.

Seat
An ergonomic seat supporting the mother during delivery, crafted with a cylindrical cutout that expands the gynecologist's sightline and manipulation area according to neonatal measurements. Its width provides ample freedom of movement and accommodates diverse body sizes.

IMPACT
Research & User Insights
The Nanti delivery bed project resulted in a peer-reviewed academic research paper titled «Design of a Surgical Delivery Bed for Vertical Childbirth» (originally presented as «Delivery Bed Incorporating a Vertical Position for Surgical Rooms»). The study validated that incorporating vertical childbirth ergonomics into surgical-grade equipment significantly improves maternal comfort, procedural efficiency, and overall satisfaction across hospital delivery teams.
