Device Story

Multiplace hyperbaric chambers (SL8, DL8, TL20) provide hyperbaric oxygen therapy (HBO) at pressures up to 3.0 or 6.0 ATA. Chambers accommodate 8 to 20 patients. Input: pressurized air for chamber environment; 100% oxygen for patient delivery via hoods or BIBS. Operation: manual electropneumatic pressurization/depressurization; venturi-assisted overboard exhaust; whisper-quiet ventilation. Output: controlled hyperbaric environment for medical treatment. Used in clinical settings by physicians, nurses, and technicians. Features include rectangular design, walk-through sliding doors, and VDU display for monitoring pressure, temperature, humidity, O2, and CO2. Benefits: treats specific medical conditions (e.g., decompression sickness, wounds, burns) while reducing patient anxiety through hospital-room-like aesthetics.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on design, intended use, and adherence to established safety standards for hyperbaric facilities.

Technological Characteristics

Rectangular steel pressure vessels fabricated per ASME Section VIII Div 1 and ASME PVHO-1. Operating pressure 3.0-6.0 ATA. Manual electropneumatic life support controls. Features: venturi-assisted overboard exhaust, pneumatic ventilation, digital depth measurement with analog backup, O2/CO2 gas analysis. Connectivity: internal/external PA system, sound-powered phone backup. Fire suppression per NFPA 99.

Indications for Use

Indicated for patients with air or gas embolism, carbon monoxide poisoning (with or without cyanide poisoning), clostridial myositis/myonecrosis, crush injury/compartment syndrome/acute traumatic ischemias, decompression sickness, problem wounds, exceptional anemia, necrotizing soft tissue infections, refractory osteomyelitis, delayed radiation injury, compromised skin grafts/flaps, thermal burns, and intracranial abscess.

Regulatory Classification

Identification

A hyperbaric chamber is a device that is intended to increase the environmental oxygen pressure to promote the movement of oxygen from the environment to a patient's tissue by means of pressurization that is greater than atmospheric pressure. This device does not include topical oxygen chambers for extremities (§ 878.5650).

#### EXECUTIVE SUMMARY

The Undersea and Hyperbaric Medical Society (UHMS) defines hyperbaric oxygen therapy The Ondersea and Hyperbart lessures higher than atmospheric in a hyperbaric chamber. as breating 100% offyger Fire Protection Association (NFPA), hyperbaric chambers are According to the National Fire Fress A (multi-occupant) and Class B (single occupant). The Classined into two outsgen Treatment Facilities are Class A multiplace hyperbaric chambers designed to treat up to 8 (SL/DL8) or 20 (TL20) patient at up to a maximum operating pressure of 3 Atmospheres Absolute (ATA) or 29.4 pounds per square maximum operating procears of 0 %... 8 %... 6 %. or 73.5 psig for the DL8 and TL20. Each incil gauge (psig) for the OLD and up tessurization gas and 100% oxygen as the hyperbaric treatment gas.

The SL/DL8 and TL20 Hyperbaric Oxygen Treatment Facilities are intended to be procured The UEDEO and TEE Fry tribate a variety of medical conditions that respond to hyperbaric and used by pryololane to trout itst of medical conditions that have been identified for the appropriate primary or adjunctive use of hyperbaric oxygen. These approved conditions

{1}------------------------------------------------

include: air or gas embolism; carbon monoxide poisoning and smoke inhalation; clostridial include. and of gas embolism, oalbert may and partment syndrome and other acute traumatic ischemias; decompression sickness; enhanced healing of selected problem wounds; lightinas, decompreasion visime rotizing soft tissue infections; osteomyelitis (refractory); radiation tissue damage (osteoradionecrosis); compromised skin flaps and grafts; thermal radiation though abscess. Aggressive research into the beneficial effects of burns, and, measure when appropriately applied, will result in additional medical conditions being added to the list of indications by the UHMS.

The SL/DL8 and TL20 Hyperbaric Oxygen Treatment Facilities are designed and fabricated in accordance with the requirements of the ANSI/ASME Boiler and Pressure Vessel Code, in abool admod will, Division 1, Pressure Vessels; ANSI/ASME-PVHO-1 (American Society of Scoton Vill, Engineers-Pressure Vessels for Human Occupancy); and, NFPA 99, Health Care Facilities, Chapter 19 (Chapter 20, 2002 Edition), Hyperbaric Facilities.

The SL/DL8/TL20 rectangular hyperbaric chamber(s) include as a key component a new and very user-friendly rectangular chamber designed and manufactured specifically for the medical community to be used for hyperbaric oxygen treatment. The design of this unique ASME PVHO chamber has been driven by comments from hyperbaric physicians, technicians and nurses who require their equipment to be simple, easy to use and to simulate toomlount and harded inical conditions found elsewhere in their working environment.

The SL/DL8/TL20 facilities place major emphasis on patient comfort and user-friendly operator controls and incorporate several innovative and unique features including:

- A large, comfortable rectangular hyperbaric chamber that has been outfitted t . appear like any other clinical room in a hospital to reduce patient anxiety
- A rectangular medical lock with a unique locking system enabling single-handed . operation
- Large walk-trough rectangular sliding doors that fit flush with the floor so that . patients can be wheeled into the chamber without bumping over a door jam
- An easy to use control panel with large VDU display to monitor the treatment . profile including the internal chamber pressure, temperature, humidity, oxygen and carbon dioxide parameters
- An oxygen delivery system with venturi assisted overboard exhaust to eliminate . the possibility of "shrink wrapping" patients with their oxygen hoods
- Whisper quiet ventilation system to pneumatically control temperature, humidity . and upper oxygen limit without the need for internal electrical blowers
- Aesthetically pleasing external chamber cladding .
