PureWick External Catheter for Women-Wick || Product Usage: || A flexible, contoured external catheter (a Wick) is positioned between the labia and gluteus muscles. The function of the Wick is to draw urine away from the body through the Wick to a storage container away from the body through a PVC tube via a continuous, low pressure vacuum pump (PureWick DryDoc) or to a hospital wall vacuum. There is never a reversal of flow direction or static state of fluid between the device and the patient. Also, the dry natural rubber component is double wrapped with 75D polyester and it is not stretched in its application to expose bare rubber to a user. The Wick does not enter the vagina (Figure 1).
