Apparatus for forming a film of blood or other body fluid sample on a microscope slide. The slide is surrounded by a member adapted to catch and immobilize excess blood thrown from the slide by centrifugal force. The member, which advantageously rotates with the slide while positioned in a waste-receiving mode, advantageously comprises a pocket filled with highly porous blood-receiving material and is adapted to be moved vertically out of the waste-receiving mode to facilitate positioning and removal of the slide from the apparatus.

Blood filming apparatus

The spherical welded tip end of a cryosurgical probe is prevented from separating and projecting from the remainder of the probe tip due to fluid pressure in the tip by a lanyard, one end of which is welded to the tip end and the other end of which is secured to a point on the main body of the probe away from the probe tip.
