GENERAL DESCRIPTION OF THE UNIVERSAL ANAESTHESIA MACHINE
®
The UAM
®
combines elements from both continuous flow and draw-over designs to provide a workstation that delivers
controlled anaesthesia in all hospital settings.
The breathing system is a low pressure (limited to 5 cm H2O) continuous flow system that defaults to a demand-flow (draw-
over) system when the supply fails. There are three one-way valves and a balloon operated inflating valve which provide this
uniquely versatile method of anaesthesia delivery.
Oxygen can be provided from a variety of sources, and if none of those sources is available the machine will automatically
draw in room air without the need for the user to change settings. The vaporizer provides calibrated delivery of anesthetic
agent and the manual bellows ensures that safe assisted respiration can continue without requiring a high pressure gas
source.
The system has been designed to accept standard anaesthesia accessories such as the breathing circuit, oxygen sensor,
and standard connectors for the oxygen and nitrous oxide supplies. The UAM is also designed for simple field service. Most
components can be removed with standard tools and local technicians can install replacement parts without removing the
UAM from the hospital.
The UAM carries the CE Mark, having passed EU regulatory inspections. It is manufactured in an ISO-certified factory in
England. It is used in a wide variety of hospitals, from internationally recognized academic centers to resource-constrained
district hospitals.
The Universal Anaesthesia Machine ensures that an adequate supply of oxygen and anaesthesia is always available to meet
patient demand, no matter what the environment.
The UAM provides several ways to deliver oxygen, including connections for cylinder and pipeline. Most importantly, the
machine produces its own oxygen using an integrated concentrator that converts room air into 95% oxygen. Air is drawn
into the UAM and is purified by 2 different filters. Ambient air is made up of 78% nitrogen, 21% oxygen and 1% other gases.
The electrically powered oxygen concentrator in the UAM removes nitrogen from room air, creating a mixture that is 95%
oxygen and 5% other gases.
The compressed air passes into a canister filled with a powdered material called Zeolite. Nitrogen sticks to the Zeolite,
while oxygen and other gases flow through it to a reservoir tank. The UAM produces up to 10 liters per minute of up to 95%
oxygen. The oxygen then travels through the rotameter bank into the back bar and reservoir bag.
GAS FLOW IN THE PATIENT SYSTEM
The flow dials control the amount of oxygen entering the back bar and available for the patient. The spinning bobbin in each
rotameter shows the flow rate in liters per minute.
The back bar provides the following functions:
1.
The reservoir bag stores up to 2 liters of oxygen.
2.
The pressure relief valve limits pressure in the back bar to 5 centimeters of water, protecting the patient from harm.
3.
The air inlet valve allows room air to be drawn in whenever the supply of oxygen is less than the demand, as expressed
by the patient’s minute volume.
