collars around the neck may save athletes’ heads - clear plastic rolls
A group of outstanding scientists have come up with a very simple strategy to prevent head injuries caused by devastating occupational movements
Collar or strap on the neck.
Including the University of Toronto. Joseph Fisher —
For example, a set of headphones worn around the neck in the game will not be tighter than the collar, which will create a "Airbag" on the skull to protect the brain from concussion.
"This is a fairly 'W' approach," says Fisher, a senior scientist in human physiology at the Toronto institute of synthesis.
"Now, we suddenly change from something like a bigger helmet to something like this. . .
It will be a simple, inexpensive, universally applied small device.
Fisher said that the sports injury specialists seeking to end the concussion plague have largely wasted their time on their helmets, which has little help in reducing the critical causes of these head injuries.
Although the helmet can protect the skull from impact rupture, it does not stop the brain from moving around in the liquid brain fluid and blood bathed in it.
It is this shaking movement that causes most of the brain damage that constitutes a concussion, Fisher said.
"As the brain shakes around the skull, it absorbs all kinds of volatile energy," he explains . ".
"The absorption of this energy can lead to the interruption of all neurons and connections, and so on.
However, by contracting the neck a little, the "inner" jugular vein that drains blood from the skull is narrowed enough to replenish the brain fluid and prevent the movement of vulnerable organs.
To explain, Fisher said to draw a clear plastic bottle with water in it and an object suspended in the liquid.
If the bottle is not full enough, if the container falls to the ground, the suspended object moves in chaos.
However, if the bottle is full of water, the suspended object remains intact at the time of impact.
The neck pressure required to keep the skull also filled with exercise to hinder blood does not need to be greater than the person wearing a tights collar shirt.
The manufacturing and sales of the equipment itself will be very simple, Fisher said.
"In fact, it's incredibly easy," he said . ".
In fact, it can be built by installing the neck guards that many hockey players have worn with several strategically placed cotton balls that compress the associated jugulars.
"That's what you did.
"It's not like a million dollar project, it will cost you ten dollars if it works," Fisher said . ".
Former Philadelphia Flying captain Keith Primeau said he welcomed any new ideas that could fight devastating injuries, and that his career was interrupted by a concussion in 2006.
But any move to introduce neck gear to hockey could start with the youth team, Primeau said, as NHL players are known to be reluctant to try new gear.
"It's like a sub-official," he said . "
"We all know that you may lose your eyes if you don't wear sunshades, but that doesn't mean everyone is wearing sunshades.
Fisher wears a pair of headphones himself.
He bent down to compress his body.
Things on the neck when riding a bicycle every day.
Humans and other mammals have two sets of jugular veins.
When a person is angry or excited, the "outside" Beast runs along the side, right under the skin and on the bulge.
The "internal" muscles run below the top of the neck muscles near the trachea and discharge blood from the brain and skull.
To show the protective effect of a slight internal Internal jugular contraction, Fisher and his colleagues observed mice, some of which were equipped with collars, while others were left collars. free.
They then performed minor head trauma on rodents during anesthesia.
The autopsy later showed serious damage to the collar.
It's free, he said.
However, there was no sign of a concussion in the collar mouse.
"We have shown proof of principle in animals that we can use simple (method),” says Fisher.
His paper has been published in the journal Neurosurgery.

Julian Gillles, a former team doctor for the Pittsburgh Steelers, also hosted a head injury study sponsored by the NFL Players Association.
Like any new medical theory, the idea needs further scientific validation, Fisher said.
But, he said, there is no harm in wearing a collar, and several NCAA class a soccer teams have expressed interest in their use.
