Definitions

  • indwelling catheters are supposed to be removed and replaced periodically to avoid infection.
  • the Foley urinary catheter for example, is supposed to be replaced a designated number of days after placement.
  • Other types of medical articles such as breathing tubes, feeding bags and blood transfusion filters, have other designated usage periods.
  • the use of the known tag and timer requires several implementation steps.
  • the clinician must attach the tag or timer to the medical article. Then, the clinician must manually write the time on the tag.
  • every second is a precious commodity in high-paced medical environments, the burden of these tasks can have a significant disadvantage, requiring too much time to implement the tag or timer.
  • the time pressures on clinicians can lead some of them to intentionally tamper with the known tag or timer.
  • a clinician might wrongfully mark-out or change the time information written on the known tag to make it appear as if the usage period has not expired.
  • a busy clinician might wrongfully keep the medical article in use while replacing its timer with a new timer.
  • the new timer would falsely indicate an unexpired usage period for the medical article.
  • This type of tampering or wrongdoing can lead to the health risks and infections described above.
  • the tamper vulnerability and complexities of the known tag and timer can frustrate the adoption and implementation of time-tracking practices by the medical community.
  • a medical timing device includes: (a) a body including a first lock member, wherein the body defines an article-receiving space configured to receive an article portion of a medical article; (b) a timer coupled to the body, wherein the timer is configured to indicate an in-use time of the medical article; (c) a triggering element; and (d) a retainer coupled to the triggering element.
  • the retainer is moveably coupled to the body, and the retainer is configured to be moved from an open position providing access to the article- receiving space to a closed position blocking at least part of the article-receiving space.
  • the retainer includes second lock member, and the retainer is configured so that, in response to a single action of moving the retainer from the open position to the closed position: (i) the triggering element activates the timer to initiate a process to indicate the in-use time of the medical article; and (ii) the triggering element causes the second lock member to become locked together with the first lock member to lock the retainer in the closed position after the article portion has been inserted in the article-receiving space.
  • the locked retainer is configured to keep the medical timing device coupled to the article portion even after the timer may indicate that the medical article has been used for more than a designated usage period. This inhibits the wrongful removal of the medical timing device from the article portion.
  • the medical timing device including: (a) a body;
  • a timer coupled to the body, wherein the timer is configured to be activated so as to indicate in-use time of a medical article
  • a retainer moveably coupled to the body
  • a lock condition in which the retainer is moved relative to the body so as to lock the body to an article portion of the medical article
  • an activation condition in which the timer is activated
  • a multi- condition trigger coupled to the body.
  • the multi-condition trigger is configured to cause both the lock condition and the activation condition to occur simultaneously or sequentially.
  • Yet another embodiment includes a method to facilitate monitoring an in- use time of a medical article.
  • the method includes the following steps: (a) providing a body; (b) providing a timer, wherein the timer is configured to be activated so as to indicate in-use time of a medical article; (c) coupling the timer to the body; (d) providing a retainer; and (e) moveably coupling the retainer to the body, wherein the retainer is moveable relative to the body so as to lock the body to an article portion of the medical article.
  • the retainer is configured so that, in response to a single action that moves the retainer relative to the body, the timer is activated and the article portion is locked to the body. The timer activation and locking can occur simultaneously or sequentially.
