Operating light
An operating theater light , also referred to as an operating theater light , is a lighting device in the operating room for illuminating the area of the body to be operated on of the patient lying on the operating table . It is comparable to that of every known dentist's operating light.
conditions
The lighting of operating theaters is standardized in accordance with DIN 5035-3 . It is a workplace lighting with artificial light . The shadow-free illumination of the operating area is hindered by the staff working in the light. The shadows cast by this can be compensated for by additional lighting elements, which is why a modern operating room light consists of several individually adjustable arms. Nowadays it is usually hung from the ceiling. It can be optimally adjusted without impairing space and mobility on the floor. A wide range of interventions in different specialist areas requires great flexibility, since the lighting must be very different and it must be possible to align it during the operation. Therefore, today usually handles of lamps sterile disguised so that the surgeon can also sterile dressed align by hand according to his needs them.
Because of the flat angle of incidence of the light, a maximum output of 160,000 lux is required for operating lights , which corresponds to the strength of sunlight. As a result, however, an undesirably high amount of heat is released with many illuminants , which stresses surgeons and patients and can dry out the tissue of the operating area. Operating lights can have a disruptive influence on the planned air-conditioning in the operating room due to their shape and heat emission . In the meantime, incandescent and halogen lamps are being replaced with more and more temperature- neutral LED lamps.
Emergency power
For obvious reasons, neither the operating field lighting nor other medical technology devices may fail during an operation due to a disturbance in the electricity supply . In outpatient facilities such as medical practices , however, there is generally no central emergency power supply operated by a diesel engine . This gap is closed by DIN VDE 0558-507 , which regulates the need for a safety power supply . For this purpose, there are battery-supported additional safety power supplies (BSV), formerly known as additional safety power supply ( ZSV static ), which supply surgical lights with a voltage of 24 volts for one to three hours in the event of a power failure .
