ABSTRACT:
A tamper-evident band for a liquid drainage system comprising an elastic catheter having an elongated shaft, a connector adjacent the proximal end of the catheter, and a drainage lumen extending through a major portion of the catheter and the connector. The tamper-evident band comprises elastomeric annular band of stepped diameter which is fit over the juncture between the connector and the proximal end of the catheter. The band has a slot longitudinally arranged on one outer peripheral portion of the band. It also has a semi-circumferential tear tab disposed on one end thereof. To separate the connector from the proximal end of the catheter, the band must be broken. The tab may be pulled and the band separated along its longitudinal slot. A small ring comprising the remaining stepped portion of the band remains on the adapter after the tab has been pulled, the slot fractured and the top band portion removed. This shows that there has probably been a band on the catheter and that the catheter has probably been separated from its connector.
