The present invention relates to an LED luminaire driving circuit with high power factor, comprising: a filter unit, a rectifier unit, a transformer unit, a power switch unit, a zero current detecting unit, a feedback unit, an error amplifier unit, and a power switch driving unit. The device of the invention comprises a liquid filled tube detachably connected to an injecting apparatus at its proximal end and to a holding and releasing unit having a bore configured to hold and release the object, at its distal end. The interconnect has a scalable maximum datum width and a scalable data path concurrency, and includes selectable data paths between any two ports to enable transfer of datums between the ports. Because the needs of patients are different and require different kinds of medical equipment the compartment configuration for one patient can be different in the present invention from the compartment configuration for another patient. When a mole fraction of the structural unit represented by the formula in the liquid organosilicon compound is \u03b1 and a mole fraction of the structural unit represented by the formula in the liquid organosilicon compound is \u03b2, the ratio of \u03b1 and n\xd7\u03b2 meets 1:3 to 1:100. The conductors are connected to one or more connectors.
