The British researchers have succeeded in developing an oxygenator device which can increase the survival rate of the wounded in battles. It is said that this device can play a great role in many emergency circumstances including nature disaster or terrorist attacks. The researchers believed that this creativity have the great significance of humanism as well as military.
Oxygen deficit of Human body would cause rapid drop down of temperature because of blood losing, and the reduction of blood coagulation factor would accelerate bleeding. The longer patients waited for treatment, the more importance of fast oxygen therapy.
Fast oxygen therapy would be very important in the remote areas when nature disaster or critical accidents happens. Besides, the explosion would cause a called blast lung injury whenever happened in terrorism or industrial accident, under that circumstance the respiratory function of human body would be hurt and drained the urgent oxygen of the injured. But if the badly injured operated the oxygen therapy in few minutes, there will be a higher survival rate.
The DSTL, located in Bourdon Down, have studied that oxygen improvement was time saving for those injured people in explosion. It was military significance, since 1 hour living, there will be more chance for withdrawing.
Stephen Lamb, consultant of Cambridge design company partner who was responsible for the research of light-weight portable oxygenator, said apart from the evidence that oxygen therapy could increase the survival rate in explosion, the injured usually could not operate the oxygen therapy before helicopter withdraw, because the battle front staff probably could not be supported by vehicles; the hydromantic oxygen tank was too heavy to carry, and easy to be shot. Though portable oxygenator was available, it was energy consuming and must equip with heavy batteries.
Lamb said: the essence of our work is to develop a portable mini-type oxygenator. Our concept is to establish combination of light-weight oxygenator and mini-type diesel engine. This is because diesel engine is more energy intensive than batteries, if necessary, this device can take the surface car or local resource as energy.
The key of creativity was how to integrate engine with oxygenator weight reduction and efficiency increase. The resolution was to have a mini-type, light-weighted and safe oxygenator device which could run for hours with less a liter diesel. This mini-type engine could supply power for emergency lighting and patient monitoring devices.
Lamb and his research team have successfully displayed the model system. Base on the before experience that they have developed medical device for civil uses, the researchers believed that they can minimum the system further and produce mini
The core of the system was the mini-diesel engine. Not only for it could avoid traditional portable system which was need the heavy battery, but also for it can extract 3L oxygen per minute to patient.
Richard Bown, who was occupied in the research, said the beauty of the system was to increase capacity when there need higher airflow rate.
The kind of model is only 2.4kg per unit, with specification of 100*200*250mm, and consumes 50g diesel only. Besides, it could use other available fuels including butane.
