See more clearly when doing surgery, Yangzhou engineers invented LED medical cold light source

When Yang Lin engineer Yuan Lin repaired medical equipment, he found that the general medical cold light source is expensive, extremely vulnerable, and has defective performance. In order to solve the problem, he led the invention of the "colorable LED medical cold light source", which can reduce the interference of the light to the doctor, improve the accuracy of the operation, reduce the energy consumption, greatly improve the life of the light source, and save money. ".

Tinted LED medical cold light source

Let the doctor see more clearly

"Under the shadowless lamp, the doctor took the scalpel and concentrated on the operation. The sweat was on the forehead. This is the classic image of a doctor in many film and television programs. For a surgery, a shadowless lamp is a necessary surgical condition. ”

Yuan Lin is a senior engineer in the equipment department of the First People's Hospital of Yangzhou City, responsible for maintaining the medical equipment of the hospital. He told reporters that human blood vessels, nerves, and a little mistake can cause irreparable harm to patients, so it is very important for doctors to see clearly during surgery. In the process of repairing the equipment, he found that the performance of various types of medical cold light sources in use is flawed, which may affect the doctor's judgment.

"The medical cold light source currently used is roughly divided into ordinary halogen light source and xenon light source according to type. They emit white light, and the light color is close to sunlight. However, each person is sensitive to different wavelengths of light, such as being sensitive to red. People under the same conditions may be more red than others see. In this way, the doctor's judgment on the wound will be biased. There is no solution for the current cold light source."

Yuan Lin introduced that he used red, green and blue three-color LED lights to create white light. “Red, green and blue are the three primary colors of light. If you use these three colors in equal proportions, you can get white light. But if a doctor is particularly sensitive to red, you can weaken the red light to make the doctor’s vision clearest and thus improve. The resolution." Yuan Lin said that this cold light source is also suitable for photographic equipment. “For example, remote consultation through the network, the camera's sensitivity error is very common, then you can adjust the light color of the light source, so that experts in the distance can see the best effect.”

Low energy consumption and long life

This invention is very "saving money"

"What we mean by 'cold light source' refers to an illuminating light source that contains almost no infrared spectrum. A led light source is a typical cold light source, while a conventional incandescent and halogen light source is a typical thermal light source. Many medical applications are now in use. Cold light sources are halogen light sources that use special materials to achieve the optical properties of a cold light source, but obviously it is not fully competent."

Yuan Lin introduced that the cold light source is not without heat. The medical cold light source that is commonly used nowadays generally has several tens of watts of power, and some of them are as high as 250 watts to 300 watts.

"The power is so high, it must be hot, the temperature is high, the contacts are easy to oxidize, the resistance increases, the light color will change, affecting the doctor's judgment. The life of this type of lamp is about 500 hours, the price is very expensive 500 yuan is very common, and some high-end light bulbs, one will cost several thousand dollars."

Yuan Lin said that the LED lamp power is only a few watts, the heat is very low, the life can reach 100,000 hours, and the price is only about 100 yuan. Considering that the medical cold light source is widely used, if it is changed to use LED cold light source, the effect of energy saving and emission reduction is still considerable.

Simple and automatic design

Easy for township doctors to use

The reporter saw that Yuan Lin's patent certificate is divided into two types: “simple multi-purpose color LED medical cold light source” and “automatic color LED medical cold light source”.

In this regard, Yuan Lin explained that the use of medical cold light sources is very wide, but because of the high price, many rural doctors can't afford to use them. He invented a simple medical cold light source that can be widely used by these medical workers. Serve the people well.

It is understood that Yuan Lin has obtained seven patents. He often uses his spare time to make some small inventions, making the work of medical staff more convenient and accurate, and medical staff often tell Yuan Lin the inconvenience of his work and ask him to find a solution.

Recently, Yuan Lin was awarded the “May 1st” Labor Medal by Yangzhou City Federation of Trade Unions. His “Invention and Development and Clinical Application of Color LED Medical Cold Light Source” was awarded the “Top Ten Advanced Operation Method” for the 5th Yangzhou City Workers. ". "A lot of people have asked me why there are so many new ideas. In fact, they are not mysterious. I am all inspiration at work. If you use your heart, you will find the shortcomings in your work. If you delve into it, you will always find a solution. The way." Yuan Lin said.
