The Need

Surgical drains are used to aid in the evacuation of exudate from a surgical site. These drains commonly connect to a drainage receptacle that is maintained by clinical staff during the post-operative period. It is common practice for providers to order the receptacles to be emptied every eight hours and to order the emptied exudate to be measured and recorded at these intervals. It is possible that a wound could secrete too much exudate, possibly signaling a hemorrhage, infection, or other problem with the surgical site. Many providers will place orders containing a threshold of allowable exudate before that provider is to be notified of the drain output. In the most serious cases, high drainage output could signal the need to return to the operating room immediately. More commonly, however, providers will monitor the eight-hour exudate totals to determine the best time to remove the surgical drain following surgery. It is common for providers to determine that, once a drain has secreted less than a specified amount of exudate in a 24-hour period, the drain is safe for removal.

.

If a drain is removed too early, the site could become infected or the patient could develop a hematoma from trapped exudate. If a drain is removed too late, the drain poses a significant risk for infection. Furthermore, the measurements obtained from drain receptacles by clinical staff are integral for making informed and accurate decisions regarding patient care. Current models of drain receptacles render complete emptying of the receptacles nearly impossible.

The Technology

Researchers at The Ohio State University have devised innovative drain receptacles to effectuate complete emptying of the drain. With efficient and complete emptying, more precise measurements of exudate volume can be made and more accurate clinical decisions can be generated. With superior information upon which to base clinical decisions, fewer patient complications will arise. In addition, the new drain receptacle design, which works with both Jackson-Pratt/grenade and pancake drains, creates a closed system, whereby patients and staff are protected from exposure to exudate.

Commercial Applications

  • Hospital exudate collection
  • Patient monitoring

Benefits/Advantages

  • Improves accuracy of exudate measurement
  • Makes emptying of waste receptacles easier and safer
  • May reduce complications for patients requiring a drain following surgery
  • Creates a closed system, which decreases exposure to exudate for patients, family, and staff
  • Improves Jackson-Pratt/grenade and Hemovac/pancake drain systems
  • Twice as effective at draining substances in proof-of-concept tests when compared to standard wound exudate drainage systems
