A basin is an open container (usually circle-shaped with 
sloping or curving sides) of various sizes for holding or 
collecting fluids. There are also basins for holding water 
for washing (e.g., hand washing). One is known as a 
wash basin and it can be a sink or bowl. There is a 
shallow bean-shaped basin often used in medical 
settings to contain water runoff when washing out 
wounds. This is known as a kidney basin (due to its 
kidney-like shape) or an emesis basin because it was 
invented as a means to capture vomit (also known as 
emesis). However, it does not actually work well to 
capture vomit because the size, depth, and structure 
cause the vomit to spill or splash over the sloping walls.
 
The basin above, pictured to the top right is commonly used in hospital settings and in 
home settings. It is commonly used to help contain vomit, particularly in young children, to 
prevent vomit from getting on the bed or couch. 
Basin can also refer to the shape of the pelvis, which resembles a basin. The pelvis is a 
massive bone made of hip bones on each side and the front, while the back part is made  
of the sacrum (a triangular bone) and coccyx (a beak shaped bone). Basin comes from  
the Latin word "bacca" meaning "water vessel."
