The rotary knob cover can be made of two square towels and is also madeof a non-woven material. Although the rotary knob cover is a disposable product, the rotary knob cover is low in cost and can be widely used. The function of the rotary knob cover is to cover a rotaryknob handle of the operating bed. The rotary knob cover can avoid cross-infection of pathogens and reduce chance of infection, and can be waterproof to avoid water inlet failure at a rotary knob of the operating bed.

Description

technical field [0001] The invention relates to the technical field of anti-sense and protective surgical drapes, in particular to an operating bed knob cover. Background technique [0002] At present, femtosecond laser surgery is widely carried out all over the world. According to statistics, 800 hospitals around the world have installed full femtosecond laser equipment, and more than 400 hospitals in China already have full femtosecond laser equipment. Femtosecond laser surgery has also been favored by more and more doctors and myopia patients. According to statistics, 2 million people around the world have received full femtosecond laser surgery, and there have been 1.2 million full femtosecond laser surgery patients in China. [0003] Then someone will ask what is a femtosecond laser? The femtosecond laser is a kind of laser that operates in the form of pulses. The duration is very short, only a few femtoseconds, and a femtosecond is 10 to 5 seconds, which is one quadri...

Problems solved by technology

According to research, among the current femtosecond users, some units use the paper handle cover in the disposable surgical bag, which has the disadvantage of being easily damaged during the operation, which affects the effect of aseptic operation

Some units use hand-sewn cotton handle covers, cotton fiber debris and dust are very easy to fall off, greatly increasing the chance of bacterial infection
