ISTANBUL - s4story -- HPO.TECH has introduced OYSTER, a single-seat hyperbaric chamber built around a structural and visual break from the cylindrical vessels that have defined the category for more than a century. The system pairs HPO.TECH's medical-grade hyperbaric platform with an entirely new chassis: an oval, organic form sealed by a full acrylic dome that lifts upward to open the chamber.

OYSTER's defining feature is that canopy. Conventional chambers seat the user inside a steel cylinder fitted with side windows. OYSTER replaces the upper half of the vessel with a single curved acrylic shell, producing a hyperbaric environment with uninterrupted overhead visibility and no structural frame across the line of sight. The interior reads more as an open capsule than a sealed device.

The form takes its name from the shape it borrows. Like an oyster shell, the upper lid hinges cleanly away from the base, giving direct access to the interior without the narrow doorway and step-over of traditional designs. Inside, an automatic reclining chair moves between an upright seated position and a fully reclined one, allowing the user to settle into whichever posture suits the session.

"For more than a century, the design of pressure vessels has remained essentially unchanged," said Tolga Kabak, CTO and co-founder of HPO.TECH. "Most hyperbaric chambers are still cylindrical steel structures. With OYSTER, we set that history aside and asked what a chamber would look like if we designed it from scratch around the person inside, rather than around engineering convention. The acrylic dome is the most visible expression of that thinking, but the entire architecture follows from it."

OYSTER operates at 2.4 ATA on the technical platform HPO.TECH has refined across its existing range. Oxygen is delivered through the company's Built-In Breathing System (BIBS), with chamber management handled through an integrated touchscreen console. Pressure, oxygen concentration, temperature and humidity are monitored in real time, with support for preset clinical protocols, secure user profiles and live session logging. An optional in-chamber entertainment screen sits alongside the control and monitoring panels, available for operators who want to offer it as part of the session experience.

Customization options follow the same logic as the ZEUGMA family. Operators can specify exterior color, interior leather selection and logo integration, with additional freedom on the lower hull given the new geometry.

Safety provisions include a reinforced lower hull paired with a thick acrylic canopy engineered to operate safely at 2.4 ATA, emergency depressurization in 90 seconds, dual automated and manual control systems, a pressure relief valve, manual backup controls, and oxygen monitoring maintained at or below 21 percent ambient levels.

Founded in 2020 in Istanbul, HPO.TECH (www.hpotech.com) designs and builds hyperbaric and multibaric chamber systems for research, clinical, wellness and high-performance applications. The company is among the most certified manufacturers in the field, holding CE, MDR, UKCA, ASME PVHO, ASME U-Stamp, PED and ISO 13485 clearances across major international markets.
