What makes the cord hospital grade: the plug. Commonly known as hospital grade plugs, they are subject to special requirements contained in the following standards: Medical equipment standards: UL 2601-1 and CAN/CSA C22.2 no 60601-1; Power supply cord standards: UL 817 and CAN/CSA C22.2 no 21; Attachment plug standards: UL 498 and CAN/CSA C22.2 no 42.
The hospital grade plug pattern conforms to the NEMA 5-15 standard; however, (1) the blades are usually solid instead of folded brass, (2) the blades are normally nickel plated, and (3) the plug includes a cable retention device or strain relief to prevent any stress to the plug's internal connections. It is imperative that the ground connection be reliably maintained to protect the patient and medical staff. Although many hospitals prefer that the plug be clear so that internal connections can be inspected visually, the UL and CSA standards do not mandate clear plugs nor do they provide any restrictions on color. North American hospital-grade cords and cordsets carry the "green dot" signifying that they have been designed and tested for grounding reliability, assembly integrity, strength and durability.
It also has low-leakage. Leakage current flowing between line and ground in electrical equipment can, under certain circumstances, present a lethal shock hazard to users. The shock hazard is usually a function of the amount of leakage current, accessibility of a “hot” surface to the user, and whether or not the user is well grounded. In patient connected medical equipment, the susceptibility of the patient to serious injury or death is increased. This is due to the low impedance path between the patient and equipment and the high probability that the patient will complete the fault circuit. Low leakage currents require special constructions in some components.
It takes 10 weeks for the cords to arrive because it is made outside the US and then shipped by boat to the US, hence the long wait time.
