1. Purpose & Use

   • Paediatric HME filters are designed for children and infants requiring mechanical ventilation or anesthesia.

   • They humidify inhaled air and filter bacteria and viruses, protecting the delicate airways of young patients.

   • Prevent drying of airway mucosa, thickened secretions, and potential lung injury.

2. Target Patient Population

   • Specifically sized for paediatric breathing circuits (neonates, infants, and children).

   • Connectors are smaller than adult versions, compatible with paediatric ventilators and resuscitation devices.

3. Structure & Components

   • Outer casing: lightweight medical-grade plastic, often transparent.

   • Filter medium: synthetic or electrostatic material for trapping bacteria, viruses, and particles.

   • HME element: captures heat and moisture from exhaled air and returns it during inhalation.

   • Connectors: typically 15 mm male/female to fit paediatric circuits.

4. Performance

   • High-efficiency bacterial/viral filtration (>99%).

   • Maintains airway humidity suitable for children.

   • Minimizes airway irritation, prevents mucosal dryness, and reduces thickened secretions.

5. Advantages

   • Combines humidification and filtration in a single, compact device.

   • Lightweight and easy to attach to paediatric circuits.

   • Disposable, lowering cross-infection risk.

   • Simple alternative to active humidifiers in short-term ventilation.

6. Usage Guidelines

   • Single-use only; replace according to manufacturer guidance or when clogged.

   • Ensure proper attachment to the circuit to prevent leaks.

   • Monitor for increased resistance or moisture accumulation during extended use.

7. Common Applications

   • Paediatric ICU ventilation.

   • Anesthesia circuits for children during surgery.

   • Emergency resuscitation with bag-valve-mask systems for infants or children.

   • Any situation requiring humidified and filtered breathing gases for paediatric patients.

Key Features

• 23-gauge size
  Medium-sized needle, offering a balance between patient comfort and efficient fluid flow.

• Sterile & single-use
  Each needle is individually sealed to maintain sterility and prevent contamination.

• Luer lock / luer slip compatibility
  Fits standard syringes depending on the design, making it widely adaptable in medical settings.

• Stainless steel construction
  Made from high-quality medical-grade stainless steel for strength, sharpness, and smooth penetration.

• Color-coded hub
  The G23 needle hub is typically blue, making identification easy during clinical use.

• Beveled, sharp tip
  Designed for smooth, low-pain insertion.

Common Uses

• Intramuscular injections

• Subcutaneous injections

• Drawing blood

• Administering vaccines

• IV line preparation (depending on protocol)

• General clinical and laboratory use
