Abstract
An epidural filter has a planar housing with a flat lower surface taped to the patient's skin. An outlet at one end of the housing is connected to the epidural catheter and opens onto the lower surface of the filter element. The inlet at the other end of the housing is shaped to receive the nose of a syringe and opens onto the upper surface of the filter element. The inlet is either fixed at an angle of about 30.degree. to the lower surface of the housing, or can be displaced upwardly to such an angle by means of a resilient portion, to facilitate connection to the inlet.
