Instructions for Use:


  • Due to reported anaphylactoid reactions to latex, it is strongly suggest that vinyl or non-latex gloves be used during the procedure.
  • All plastic/rubber accessories are disposable, single-use devices that must not be reused or left in the body cavity for an extended period of time.
  • Fluoroscopy may be used to visualize rectum with contrast medium to ensure absence of contraindications. (See CONTRAINDICATIONS.)
  • For double contrast studies, use an enema tip for air contrast (not included) and follow the stated instructions for use.
  1. Connect enema tip to tubing of enema bag.
  2. Lubricate enema tip with desired lubricant and carefully insert into the patient’s anus. Care must be taken during insertion of the enema tip not to exert undue pressure to the neuromuscular plexus, which can lead to vasovagal reactions and syncopal episodes. Forceful or deep insertion may also cause tearing or perforation of the rectum.
  3. Release the clamp on enema tubing and administer the desired quantity of the barium suspension.
  4. Discard entire enema kit with tip (these are intended for single use only.)
