Reimers Systems Inc., has been a producer of quality breathing simulators and life support equipment for over 20 years.  RSI's Personal Breathing Apparatus Test Station (PBATS) represents a masterful integration of that experience with easy-to-use, state-of-the-art technology. The PBATS is designed to accurately test and document the performance of a wide variety of breathing apparatus, such as those used for:

DIVING, FIREFIGHTING, MINE RESCUE, AEROSPACE.

 

 General Features:

o  State-of-the-art technology, laboratory accuracy.

o  Compact, portable

o  Fully functional and ready to go to work.

o  Versatile and upgradeable.

o  Simple and robust design

 

Lung Module:

o  Computer controlled:  Waveforms are initially provided for ventilation rates of 15,  22.5, 40, 62.5, 75 and 90 liters per minute with industry standard tidal volumes and a sinusoidal pattern. These waveforms can be easily added to or modified.

o  Extremely accurate, even with heavy breathing resistance.

o  Versatile:  can produce any physiologically reasonable waveform.  Can be placed within a pressure vessel while the control module remains outside (optional wire feedthru kit is available).

o  Smooth waveform generation, even at low RMV’s, by use of a zero-backlash ball screw & servo motor drive.  None of the roughness in motion associated with stepper motor drives.

o  Easy to use and maintain:  design is elegantly simple and thus reduces potential testing anomalies.

o  Overload protection in the event of gas port blockage.

o  Device leakage protection:  breathing circuit collects and allows for on-line draining of water (for wet testing applications).  Tests do not have to be aborted due to nuisance leaks.

o  Instrumented:  includes respired volume and pressure transducer.

 

 

 

Data Acquisition and Control Module:

o  Personal Computer:  Latest standard PC included or customer can provide one for credit.

o  Data Acquisition Board: 8 analog input channels. 110 or 220 VAC power user specified.

o  Servo control system: digital motion controller and power supplies.

 

Software:

o  Motion control is provided by a versatile and general servo control program that provides a broad range of control options or can be modified as necessary using a simple control language.

o  An Excel spreadsheet is provided that calculates work of breathing and peak

        respiratory pressures for the device being tested. This program also     prepares the data for printing.

o  A commercial data acquisition program is also provided for setting up test protocols and handling test data received thru the data acquisition board.

o  All data acquisition and manipulation processes have been developed and proven in Reimers’ own pressure test lab under rigorous project conditions.

 

Other:

o  High quality calibration pump and manometer for pressure transducer calibration.

o  Comes secured within rugged, re-usable containers for shipping.

 

 

 

 

Options:

o  Wire feed thru kit (for using the Lung Module within a pressure or altitude chamber)

o  Water Test Tank

o  Temperature and Humidity Control

o  C02 add System 

o  Larger tidal volumes

o  Manikin head

 

 

 

 

 

 

 

 

Specifications Summary:

(Standard Unit,  All units are built to order. Consequently, units can easily be tailored to nearly any set of user requirements.):

Operating Environment

·        Indoors

·       In normal air environment

·       Can be placed inside a Hyperbaric chamber where an 80 volt dc motor is acceptable

·       The lung module can also be placed outside of a hyper-baric chamber with pipes run-ning into the chamber to the apparatus.  When used in this way, the maximum internal working pressure is 100 psig.

Standard Breathing Waveforms

·        15 liter per minute (lpm) sine wave1.0 l tidal volume, 15 bpm

·        22.5 lpm sine wave 1.5 l tidal volume, 15 bpm

·        40 lpm sine wave 2.0 l tidal volume, 20 bpm

·        50 lpm sine wave 1.0 l tidal volume, 50 bpm

·        90 lpm sine wave 3.0 l tidal volume, 30 bpm

·        30 lpm square wave 2.0 l tidal volume, 15 bpm
