Infusion Solution Pump
Abstract: The pump: is provided with a sloped surface (21a) on the main finger (21) the surface sloping at an angle with respect to the direction of forward and backward movement; is provided with a sloped surface (23a) on an accessory finger (23) the surface being capable of sliding relative to the sloped surface (21a) of the main finger (21); and is configured so that when the main finger (21) moves forward the accessory finger (23) moves backward in proportion to the change (increase) in the total width of the infusion solution tube (T) and when the main finger (21) moves backward the accessory finger (23) moves forward in proportion to the change (reduction) in the total width of the infusion solution tube (T). The configuration makes it possible to limit the occurrence of a gap between the tip of the accessory finger (23) and the outer circumferential surface of the infusion solution tube (T) during the forward or backward movement of the main finger (21) thereby making it possible to prevent the twisting of the infusion solution tube (T) and limit reductions in the precision of infusion solution flow.
