Abstract
The present invention is directed toward an apparatus for producing consistent blood and bone marrow smears. The apparatus may include a smearer configured to receive a planar smear slide. The smearer may include an angled portion that comes into contact with the planar smear slide and creates the smear. The apparatus operates by allowing users of all skill levels to prepare a blood or bone marrow smear sample.
Claims20
An apparatus for producing blood and bone marrow smears comprising:
- a slidable smearer configured to hold a planar smear slide, the slidable smearer including a left portion, a right portion, and an angular spreader portion;
- and
- a top portion connecting the left portion and the right portion, the top portion having a proximal end of the angular spreader portion connected thereto and protruding from at least one end of the top portion;
- wherein
- the angular spreader portion is configured to spread and smear at least one of blood and bone marrow placed on the planar smear slide when the slidable smearer is slid along a length of the planar smear slide, the angular spreader portion being positioned at an acute angle relative to the planar smear slide to control the thickness of the smear;
- and wherein,
- the slidable smearer comprising grooves configured to receive the planar smear slide and allow the planar smear slide to slide in a longitudinal direction along a length thereof.

An apparatus for producing blood and bone marrow smears comprising:
- a slidable smearer configured to hold a planar smear slide having a first width, the slidable smearer including a left portion, a right portion, and an angular spreader portion having a second width, wherein the first width of the planar smear slide is greater than the second width of the angular spreader portion, the left portion and the right portion of the slidable smearer including an inner surface and an outer surface having grooves, the grooves configured to receive the planar smear slide and allow the planar smear slide to slide in a longitudinal direction along a length thereof;
- and
- a top portion connecting the left portion and the right portion, the top portion having & proximal end of the angular spreader portion connected thereto and protruding from at least one end of the top portion, the angular spreader portion including a proximal end and a distal end, the proximal end of the angular spreader portion connecting to the top portion of the slidable smearer, and the distal end coming into contact with the planar smear slide at an acute angle;
- wherein
- the angular spreader portion is configured to spread and smear at least one of blood and bone marrow placed on the planar smear slide when the slidable smearer is slid along a length of the planer smear slide.
