Suction tubes are used in all areas of surgery and come under surgical instruments, dentistry instruments as well as gynecological instruments. These suction tubes are not only found in the operation room but they are also found in an ambulance in case any liquids need to be cleared away from a patient in a state of emergency. These tubes attached to suction machines are also found in clinics and hospital rooms. The suction tubes each perform a particular application which is why the suction machine has a number of suction tubes attached to it.
