ABSTRACT:
A microbiological specimen sampling device capable of operation by one hand to both expose the sample collector and obtain contamination-free specimens consists of a catheter assembly including: an outer catheter and an inner catheter, each having distal and proximal ends, a sample collector disposed generally within the inner catheter and having operating structure for extending the sample collector beyond the distal ends of the catheters to obtain a sample, and a removable, water soluble plug engaging and sealing a portion of the outer catheter in a position between the distal ends of the outer and inner catheters. The device also includes structure for moving the outer catheter axially with respect to the inner catheter consisting of a first handle member at the proximal end of the outer catheter, and a second handle member at the proximal end of the inner catheter and located proximally of the first handle member, the handle members defining respective surfaces adapted and arranged for operating engagement by different digits of one hand of an operator to be drawn together to cause relative axial movement of the inner and outer catheters to dislodge the plug from the outer catheter by pushing-out motion of the inner catheter, and the device includes structure for operation of the sampling device by a digit of the same hand while grasping the proximal end of the catheter assembly.
