Definitions

  • a colonoscopy is an examination of the large intestine or colon through the use of a colonoscope.
  • a colonoscope is a flexible, tube-like inspection device having a camera at its end. Colonoscopies are performed for a variety of medical reasons including detection of inflamed tissue, ulcers, abnormal growths or polyps, and colorectal cancer. Colonoscopy is increasingly used as a screening tool to detect colorectal cancer.
  • a colonoscope is inserted into a patient's rectum and then advanced to the beginning of the colon (an area known as the cecum) in order to examine the lining of the large intestine.
  • the efficiency and accuracy of this procedure is largely dependent on the ease with which the colonoscope can be advanced.
  • the colon may become over-distended or flopped in unnatural directions creating loops that hinder the advancement of the colonoscope and resulting in patient discomfort, longer examination times, and potentially inaccurate or incomplete screenings.
  • a method and apparatus for applying pressure to the abdomen of a patient is provided to ease the passage of an endoscope during procedures used to examine the bowels including colonoscopy, sigmoidoscopy, and enteroscopy.
  • Aspects presented herein exert both broad, uniform lower abdominal pressure as well as additional, location-specific pressure upon the sigmoid colon for the purposes of preventing and reducing intestinal looping, eliminating the need for the application of manual pressure, improving patient safety, comfort, and satisfaction, and preventing musculoskeletal injury to endoscopy healthcare providers.
  • aspects include a primary wrap sized for placement around a subject’s lower abdomen and at least one secondary strap extending from the primary wrap and configured to extend across at least a portion of the primary wrap and to fasten to a third portion of the primary wrap to adjust the amount of pressure applied by the endoscopy support apparatus.

  • the primary wrap 10 may have a circumferential length between approximately 15 and 75 inches in order to accommodate varying abdominal girths in patients.
  • the width of the primary wrap 10 may be between 6 and 10 inches, although variations having widths of between 3 and 20 inches may be used depending on the size of the patient and to accommodate special circumstances such as an abdominal hernia or a large pannus.
  • the primary wrap may be configured to have a width that allows it to be fastened around the patient’s lower abdomen with the upper edge of the wrap just below the umbilicus, or near the umbilicus, and the bottom edge of the wrap along or close to the pubic line.
  • the width of the primary wrap may be selected so as not to be so large that the upper edge conceals the umbilicus and additional areas of the abdomen above the umbilicus. This configuration may be made in order to avoid pressure on the diaphragm or stomach, as pressure on the diaphragm and stomach during colonoscopy can increase the risk of oxygen deprivation and aspiration events, respectively, due to the fact that the patient is generally sedated during the procedure.
  • the primary wrap 10 may comprise, entirely or in part, a flexible, bio-compatible foam, rubber, neoprene, polyester, nylon, non-woven or woven fabric, mesh fabric, synthetic fabric, microfiber fabric, silicon or vinyl plastic, or any other materials generally known to be used in medical fabrics and goods.

This hook strip 13 may be fastened to the exterior side of the opposite end of the primary wrap 10.
  • the edges of the hook strip 13 might not extend to the edges of the primary wrap 10. This construction may be designed to minimize the chance that the hook strip 13 comes into contact with the patient’s skin, or with the gloves of the nurse or assistant deploying the device, as there is a small but known risk of VELCRO®, or a hook and pile material, being capable of tearing medical gloves.
  • An additional feature designed to reduce the likelihood of patient and provider contact with the hook material.
