Vital Hollow Fiber Dialyzer - 14LF Pack of 24 (V-14LF)

Vital V-14LF is a single-use, mid-flux hollow fiber dialyzer for maintenance and acute hemodialysis in adult patients with chronic or acute renal failure. It is the smallest model in Vital's LF series, which runs from the V-14LF to the V-24LF, and is the one dialysis units most often specify for lower blood-flow prescriptions and smaller patients.

Dialyzer selection remains the treating nephrologist's decision. The fibres are polyethersulfone (PES), a BPA-free membrane with a 40 µm wall. Vital's own comparison puts a great balance between mechanical strength and diffusive performance.

PES resists protein, surfactant and polysaccharide adsorption better than polysulfone, according to the manufacturer. The housing is BPA-free, DEHP-free polypropylene (PF series), and each unit is irradiation-sterilised. Effective surface area 1.4 m². Ultrafiltration coefficient 14 mL/h/mmHg, which places it in the mid-flux band: more small-solute and middle-molecule removal than a low-flux dialyzer, without the high-flux need for ultrapure dialysate at every station. Maximum transmembrane pressure 600 mmHg.

In-vitro clearances at a blood flow of 200, 300 and 400 mL/min: urea 190, 252 and 280 mL/min; creatinine 182, 233 and 262; phosphate 180, 227 and 267; vitamin B12 115, 131 and 141.

Features:

• Efficient Clearance: Supports urea clearance and removal of small molecular metabolic waste during hemodialysis.
• Controlled Fluid: UF coefficient of 14 mL/mmHg/h supports controlled ultrafiltration during treatment.
• Biocompatibility: Polyethersulfone (PES) membrane provides biocompatibility for blood-contacting dialysis applications.
• Reduced clotting risks: Designed to support a significant reduction in clotting risks.
• Single-use design: Disposable dialyzer intended for individual hemodialysis treatment applications.

• Membrane: Polyethersulfone (PES) hollow fibres, BPA-free.
• Hydrophilic:Hydrophilised for wettability Housing, end caps and ports: polypropylene (PF series).
• Fibre Potting Compound: Polyurethane.
• O-rings and seals: Silicone Latex not used in the fluid path.
• Sterilant residues: None 

Intended for use and operation by by trained dialysis staff under a nephrologist's prescriptio

• Check before opening. Confirm the model (V-14LF, 1.4 m²) against the prescription. Do not use if the pouch is damaged, the caps are missing or the expiry date has passed.
• Mount. Fix the dialyzer vertically in the holder with the arterial (red) port at the bottom and the venous (blue) port at the top for priming.
• Connect the blood lines. Remove the port caps. Screw the arterial line's luer-lock onto the red inlet port and the venous line onto the blue outlet port. Attach the transducer-protector lines to the machine's arterial and venous pressure ports.
• Connect the dialysate lines. Attach the Hansen connectors so that dialysate flows counter-current to blood, dialysate in at the top and out at the bottom.
• Prime and rinse. Prime the blood compartment with sterile heparinised saline per unit protocol, tapping and rotating the dialyzer to clear air from the header. Rinse the dialysate compartment with the machine's priming programme.
• Start treatment. Invert the dialyzer so the venous end is up, connect the patient, and run blood flow and dialysate flow at the prescribed rates. The clearance figures on this page were measured at QB 200 to 400 mL/min.
• Monitor. Keep transmembrane pressure below 600 mmHg. Watch arterial and venous pressures, air detector and clotting in the header; follow the unit's anticoagulation protocol.
• Finish and dispose. Return blood per protocol, disconnect, and discard the dialyzer in the biomedical waste stream.
