What is drip chamber for disposable iv infusion drip set?

Function

Drip chamber(see product details) is an essential part of iv infusion drip set which mainly works for:

• observing flow rate of  of medication: a drip chamber should be transparent to make it easy for nurses or patients to observe medication flow rate.
• controlling flow rate of medication: by observing medication flow rate and adjusting the flow regulator, nurses can control medication flow rate.
• avoiding bubbles: the design of drip chamber will be helpful to reduce bubbles flowing into iv tubing, this will largely ensure infusion safety.

Components

A drip chamber commonly consists of spike cover, plastic spike, air vent, air filter, chamber, solution filter.

• spike cover: made by PE, used for keeping spike sterile.
• plastic spike: made by ABS, used for penetrating infusion bottle stopper.
• air vent: made by PVC, used for enabling or stopping air to flow into chamber.
• air filter: made by, used for preventing micro organisms from entering chamber and infusion bag.
• chamber: made by PVC or DEHP-FREE PVC, used for observing and controlling fluid flow rate.
• solution filter(see product details): made by ABS(shell) and PP(filter), used for preventing unnecessary particles from entering iv tubing.

Performance

• Transparency

Drip chamber should be highly transparent to be convenient to observe fluid flow rate and fluid surface.

• Material Safety

Material to produce a drip chamber should be totally conformed with medical standard: non-toxic, non-sensitization, and resistant to chemical corrosion, to prevent medication from pollution and patients from adverse reaction.

• Sealing Performance

Connecting part between drip chamber and iv tubing should be sealed perfectly to prevent fluid leakage or air entering.

• Pressure Resistance

Drip chamber should be able to bear the pressure change during infusion, with no deformation or cracking, otherwise it will affect infusion safety.

• Drop Speed Control Accuracy

Drip chamber should be designed to have stable flow rate, and should ensure that flow rate can be accurately controlled by flow regulator.

• Anti-bubbles Design

Drip chamber should effectively prevent bubble from entering iv tubing, otherwise it will cuase air embolism endangering life.

• Easy to Operate

Drip chamber should be easy to assemble and disassemble.

• Durability

Drip chamber should be with good durability, not easy to age or damage.

• Biocompatibility

Drip chamber should be compatible with human tissue and should’t cause exclusion reaction with human tissue.
