Dear WW: the blood pressure measurement device is called sphygmomanometer. I cannot think of any special names for the other things you mentioned. When it comes to having blood drawn, there is no advantage to having a fine needle used. People who exercise a lot have large veins easily seen close under the skin, but everybody has veins deep that are large enough for experienced lab lady to find. A very fine needle would take longer to pass the amount of blood required, and I think there is some possibility of red cells being damaged by too fine a needle. Let the lab lady decide.
