What are the new requirements of LED medical light in today's medical environment?

LED surgery shadowless light plays a very important role in medical industry. With the development of medical device, it design requirement also is improved. Then, under the current social development trend, what requirements should be met for the design of LED operating lights?

1. LED mobile operation lamp intensity should be suitable for the needs of the simple operating room

Some simple operating rooms have poor lighting requirements, when choosing operating light, you need to consider its illuminance firstly. Generally the single dome operation lamp illuminance can reach 150,000 Lux. If you have enough budget, another satellite light can be chosen as auxiliary light, maximize the elimination rate.

2. The power of LED operation lamp should meet the power supply standard of simple operating room

When surgical lamp factory sells surgical lamp to customers, the power should be noted. Too high or too low voltage can cause the surgical shadowless lamp to be unusable, resulting in the burning of the components inside.

3. Whether the LED surgery light can be moved in simple operating room

In some areas, especially in areas where natural disasters are more serious, the simple operating room itself is faced with a variety of risks, and there is a possibility of moving away at any time. Under such circumstances, the ordinary ceiling-mounted shadowless lamp is not as convenient to install and disassemble as the vertical portable surgical lamp. The hospital can choose the appropriate operating room shadowless lamp according to its own situation.

4. With camera function

With the development of medical digital imaging technology, the operating room can install hospital operating lights with camera function, wired or wireless camera, internal or external camera. Through the medical camera, you can diagnose and record the operation process when dealing with complicated surgery, or you can get expert help remotely.

Why is it recommended to use LED light source as the first choice for shadowless lamps?

In order to maintain good and stable operating room light environment, the operating room should be protected from direct sunlight, or colored glass can be used to facilitate artificial lighting.

Due to the high illumination requirements of the operating room, the installation position of the lamps is often limited by the number and location of the air outlets and other equipment. This is not only asked to meet the high illumination, but also the number of lamps should be limited to the appropriate range, and the energy consumption of the operating room air conditioner should be taken into consideration. The heat of the bulb should be as small as possible. It is recommended to use LED light source. Since the LED is cold light source, there is almost no temperature rise in the room, the patient has no uncomfortable feeling, and the risk of dehydration caused by the light source is avoided. In addition, it can also reduce the energy consumption of indoor air conditioners properly; the general light CRI of the operating room should be close to natural light, preferably between 4000 and 5000K, usually with a color rendering index of Ra≥90.

General lighting in the operating room should not use traditional magnetic ballasts, surgery shadowless light powered by conventional magnetic ballasts will be strobed due to AC power. Doctors perform surgery under this ever-changing stroboscopic light source. The visual system needs to constantly adjust the size of the eyeball pupil to ensure the stability of the retina illumination and imaging clarity. Long-term work will inevitably make the pupil sphincter fatigue due to excessive use. It will have an adverse effect on the surgery and will also cause some damage to the doctor's vision.

The AC electronic ballast is a new type of rectifier composed of rectification and filtering, high frequency oscillation and rectifier coil protection circuit. Since the power frequency is greatly increased to 55 kHz, even 80 kHz, 100 kHz super audio, the flicker frequency of the operating light is correspondingly increased to the area where the human eye is not sensitive, which alleviates the stroboscopic effect. At the same time, the buzzer interference is completely eliminated, the power consumption is greatly reduced, and the power factor of the operation lamp is improved. Electronic ballasts have great advantages at low voltages, but unfortunately, the ultra-high frequency also brings another adverse effect, that is, electromagnetic interference generated by high-frequency oscillations, that is, said that the higher the power frequency, the more serious the electromagnetic radiation phenomenon. With the development of modern medical technology, the precision electronic medical equipment used in the operating room is increasing. The electromagnetic interference influence of many electronic ballasts on the normal use of these devices cannot be ignored. For example, in cardiothoracic surgery, when the patient installs pacemaker, it may also be dangerous due to electromagnetic interference.

In summary, to solve these two problems, it is recommended to use LED light source mobile operation lamp, LED working mode is driven by external or built-in power supply, no ballast is needed, so the problem of strobo can be effectively solved, the good quality LED lamp can almost achieve no stroboscopic; In addition, the use of high-end isolated power supply can effectively reduce the electromagnetic interference of the lamp for precision instruments and prolong its life.

What is the auxiliary surgery light advantage?

Most people are familiar with ceiling surgery shadowless light, but for operating light, there are also have other types, such as wall mounted operating light, mobile operation lamp. Those operation lights can bring great convenience in the right environment. As professional surgical lamp factory, Shandong Mingtai company glad to introduce mobile operating light to you

Mobile surgical lamp is one type of auxiliary surgical lamp. Its advantages are as below:

1. Small size and easy to install

Compared with ceiling operating light, mobile operating lamp only needs few minutes to install it, saving labor cost. And in underdeveloped areas of medical care, mobile surgery lamp can be moved from one operating room to another operating room, very convenient for medical staff to carry out surgery.

2. Competitive price

For some small clinics, the price of overall reflection shadowless light is too high. The mobile operating light not only can be moved easily, but also has competitive price. And it illumination is not less than other surgery lamp when doing simple surgery, it can be called as an economical surgical lamp.

3. Auxiliary light, backup light

Sudden conditions such as trips and short circuits may occur during surgery, it will greatly threaten the safety of patient if those conditions occur. In this situation, the mobile shadowless lamp, with its inherent advantages, can appear immediately in the surgical illumination area where it is needed, ensuring normal operation.

Suggestion for purchasing surgery light

First of all, when you choosing surgery shadowless light, you should not only notice its performance, but also pay attention to its safety, whether it is strictly implemented in the manufacturing according to the relevant safety standards, these two are more important.

Secondly, you can’t just look at the appearance of the operating light when you choose it, the appearance of shadowless lamp is very importance for us, but the biggest role of the operating lamp is to help us to control the surgical field more accurately during the operation. If surgical light is only good-looking, color reproduction and illumination parameters are out of the industry standard, this will not guarantee the safety of our surgery.

1. Safety

For surgical lamp factory, safety is always the most important goal. The safety here refers not only to the goods themselves, but also to the safety of the users and the objects they use. At present, the domestic and foreign standards of operation lamps are very mature, and some domestic testing standards are higher than the European norms. Most manufacturers have higher standards for medical devices, so there is little safety problem in their products. However, due to the complexity of the design, the device installation is not in place, or the training is not in place, which may cause problems during use.

2. Suitable lighting environment

In one operation, the doctor is focused on the surgery field 90% of the time. Other medical staff will check the condition of the surgery field most of the time. A suitable lighting environment can make the medical staff see clearly and watch for a long time. "See clearly" can be interpreted as color is not distorted, can distinguish tissue organs, and no shadows.

3. Operate easily, sensitively and precisely

Light head and arm are important parts for mobile operation lamp. Before and after the operation, the head of the surgical shadowless lamp needs to be able to move quickly into and out of the operating area. During the operation, the lamp head should be sensitively adjusted in angle and position according to the needs of the doctor, and it is necessary to adhere to precise positioning during long-term surgery without drift.

LED shadowless lamp common fault solution

Surgery shadowless light is a medical lighting tool used by medical personnel to observe the incision of the surgical field and different depths of tissue in the body cavity. Shadowless lights often have a variety of sudden failures during use. As professional surgical lamp factory, Mingtai company summarized the common faults of operating light for everyone.

1. The main light is off and the auxiliary light is on. ZF series operation light has automatic switching function in the circuit control. When the main lamp is damaged, the auxiliary lamp will light up to ensure normal operation. After surgery, the main lamp bulb should be replaced immediately.

2. Light is not on. Open the top cover, check the transformer and power supply voltage to see whether thay are normal, if both are no problem, please find a professional to repair.

3. Transformer damage. There are generally two reasons for transformer damage: Supply voltage and excessive current caused by short circuit. The latter should ask a professional to repair.

4. The bulb is often damaged. Check whether the bulb is configured according to the rated power specified in the instruction manual and whether the power supply voltage is normal.

5. Disinfection handle deformation. Mobile operation lamp handle can be autoclaved, but the handle can not press heavy objects during disinfection, otherwise it will cause the handle deformation.

6. Move operating light angle, the light is off. This is mainly because the sensors at both ends of the arm will cause poor contact after a period of use. In this case, the professional should be asked to maintain it once.

7. Lamp head drift. After using for a period of time, due to the heavy weight of the operating lamp head, a large friction force is required for positioning, lamp head drift is generated, the upper positioning screw can be tightened to solve the problem.

8. Surgery shadowless light dims. Reflective glass for cold light shadowless lamps using coating technology. Generally domestic coating technology has only two years of life, after two years, the coating layer will cause problems, the reflection will become dark and foaming. In this case, you need to change the reflective bowl.
