Herniated disc sufferers at Vancouver General Hospital are being treated with ozone/oxygen treatment to reduce the size of their herniation (lower back) and ultimately reduce their pain and suffering.
The oxidating effect of the ozone/oxygen appears to shrink the disc and pulls the herniation away from the irritated nerve.
“There was a strong suggestion that patients got better more rapidly with the treatment. What we’re hoping to see here is that through the ozone process, healing will occur rapidly and patients won’t need other interventions like repeated steroid (cortisone) injections and surgery,” said Dr. Peter Munk, the lead radiologist in the study.
“The disc is like a fibrous doughnut and you get a herniation when an inner part of the disc bulges out through a weakened area,” Munk said, adding that the majority of herniations occur in the lower back, potentially leading to pain in the back and legs by pinching on spinal nerves.
The studies main objective (now recruiting 25 participants) is to determine the safety of the injection delivery system. CT imaging is used to precisely guide the needle (similar to what is used in complicated epidurals.
The whole process takes approximately 20 minutes and is an outpatient service.
The procedure should reduce the cost to the health care system compared to more traditional treatments (surgery etc) and reduce the level of complications patients have to endure.
Dr. Kieran Murphy (University Health Network) developed the treatment (AO-1000) which is owned by Active-O Inc.
The treatment is available in other countries however the new device is handheld and utilizes a syringe delivery system.
For the patient, it adds another layer of treatment before having to consider surgery which many people view as a last resort.
The purpose of this article is to explain the main types of oxygen generators available for ozone production and the advantages/disadvantages of each.
There are a few manufacturers of oxygen generators and a few differences between each. However, the fundamental operation of each manufactures version is very similar so that will not be reviewed here. We will focus on the three main styles of oxygen generators and how they could be implemented into your ozone generation system.
Generally smaller ozone systems will use the turnkey oxygen generators, and larger ozone systems with higher ozone production rates will use the industrial oxygen generators, while small to medium integrated ozone systems will use the OEM modules. However, there are applications where the industrial style oxygen generator is required for higher pressures, or turnkey oxygen generators are required due to the lack of space or available compressed air.
Turnkey Oxygen concentrators
Packaged oxygen generators that include an oil-less compressor, PSA oxygen generator, and all components to concentrate oxygen from ambient air. These units only need electrical power for operation and will provide oxygen at 93% purity.
OGSI, OG-15 and OG-20
AirSep, AS-12 and Onyx
Sequal (Chart), Workhorse line
Compact size allows for install in relatively tight spaces
Turnkey design allows for quick and easy operation
Relatively low cost
Lower oxygen output delivery pressures due to limitation of internal oil-less compressors
Poor reliability due to the lack of ability to purge moisture from process air
High maintenance costs due to poor reliability
OEM models are offered by both OGSI and Sequal (Chart). The OEM modules use the same PSA sieve beds and valving systems as the turnkey packaged oxygen generators provided by those companies. These modules are commonly used to build ozone generators with integrated oxygen generators, or smaller integrated ozone systems.
Compact size allows for install in relatively tight spaces
OEM configuration allows for installation into the same enclosure as an ozone generator if desired
Use of compressed air from plant air compressor may allow for very clean, dry air to be used increasing reliability dramatically when compared to the turnkey packaged oxygen generators.
Can provide slightly higher oxygen delivery pressure than turnkey packaged oxygen generators due to the higher compressed air inlet pressures that can be used
Lowest potential operational costs if plant compressed air is used
Installation equipment is required and must be done properly for reliable operation
Lower oxygen output delivery pressures than industrial oxygen generators
Potentially high replacement costs (applies to Sequal/Chart ATF-modules)
Industrial Oxygen concentrators
Industrial oxygen concentrators are used for medium to large scale ozone generation systems. These systems require compressed air for operation along with proper plumbing and set-up. Large steel cylinders are used to hold the molecular sieve material, and quality rebuildable solenoid valves are used to perform all purging and oxygen recovery actions.
OGSI, OG-25, OG-50, OG-100, etc
AirSep, AS-A, AS-B, AS-D, AS-E, etc
Long term reliability of the system – only periodic maintenance is required
Lower overall long-term operational costs than other options due to low cost for rebuilding the unit
Higher oxygen delivery pressures (45 – 65 PSI)
Higher oxygen flow-rates available
Higher up-front capital costs for oxygen generator, tanks, and potentially the air compressor
We have a great video (see below) of our CH-1 ozone chamber in action. This video shows the operation of the CH-1 ozone chamber, but also is a great demonstration of the oxidizing power of ozone and how different materials react to ozone.
A latex glove is on the right while a silicone glove is on the left. On the bottom, there is a glove stretched over a roll. On the top, the glove is simply hanging from a wire. It is clear the latex glove is oxidized much faster. However, it is important to note that silicone is also not completely ozone resistant.
