Medical Tubing Clamp

The MSA-110 tubing clamp is a disposable, scissor-style plastic clamp designed to occlude (fully pinch off) flexible medical tubing. According to the manufacturer’s specifications (McKesson brand), it is 4-7/8 inches long, made of rigid plastic, non-sterile, and intended for single use. In practice, this clamp serves as a simple on/off valve in IV and fluid lines: when closed, it completely stops fluid flow through the tube. Because it contains no metal parts or rivets, it can safely be discarded in regular medical waste without special recycling concerns.

• Key Features: 4-7/8″ total length; injection-molded plastic construction; non-sterile, disposable; scalloped jaws for firm grip. This McKesson MSA-110 clamp is explicitly labeled as a “tube occluding” (flow-stopping) clamp. It is lightweight yet durable, providing a reliable pinch on tubing without damaging it.
• Operation: Pointed scissor-style jaws close fully to stop flow instantly. Unlike roller clamps (which adjust flow rate), this clamp is simply opened or closed by pinching the tabs. It locks tubing closed for procedures where fluid must be held rather than metered.
• Compatibility: Designed for use with soft medical tubing (e.g. IV lines, dialysis lines, suction tubes, etc.). The clamp will fit any flexible plastic tubing that needs to be completely shut off. It does not have sharp blades, so it does not cut the tubing; it just pinches it flat to block flow.

Typical Uses

These plastic tubing clamps are common in many clinical and laboratory settings. For example:

• Intravenous (IV) Therapy: The clamp is often placed on an IV extension or infusion set to halt fluid or medication flow when a line needs to be changed or secured. In IV setups, such clamps are used to “cap off” the line without disconnecting it, preventing any further infusion.
• Dialysis and Apheresis: During dialysis treatments or blood-collection procedures, tubing clamps like the MSA-110 are used to fully occlude dialysis tubing to stop blood or dialysate flow at specific times. In these contexts, disposable plastic clamps are preferred because they provide a firm seal and can be thrown away after use.
• Laboratory/Other Medical Procedures: In labs and ward procedures (e.g. blood sampling, tube flushing, autotransfusion setups, etc.), these clamps are used to temporarily stop flow in plastic tubing lines. They are handy whenever a short-term “shut‐off” is needed without introducing air or disconnecting a system.

According to product literature, the MSA-110 clamp’s design “is a 4-7/8 inch plastic clamp designed for occluding and stopping flow through tubing,” and it is made non-sterile and disposable for convenience. It is supplied in bulk (typically 25 clamps per bag, 100 per case) for use wherever flow control on disposable tubing is needed.
