Safe, easy-to-handle and tamper-evident, an ultra-sharp double-bevel introducer needle plus a medical grade lubricant allow for easier penetration and smoother travel through tissue. Preview chamber in clear sure-grip hub gives immediate indication of proper placement. Flexible thin wall catheter with large inner diameter assures good blood flow. Each Surflo Catheter is individually packed in a sterile, easy-to-open plastic case. This rigid plastic case provides added protection to both the catheter and the user. The case is colour coded for easy identification of the catheter gauge and has a tamper-evident seal for additional safety. The colour coded catheter hub is translucent, making it easy to confirm continued access in the lumen of the vein and helps to monitor solution or blood flow.
