In modern clinical practice, maintaining precise intravenous flow rates without relying on powered volumetric electronic pumps presents a critical operational challenge. Traditional gravity infusion sets utilizing standard manual roller clamps suffer from severe flow drift, cold-flow plastic creep of PVC tubing, and position-dependent delivery shifts. Clinical studies show flow variance up to ±40% over a 4-hour period when using conventional clamps.
The Lars Medicare Dial Flow Regulator bridges the gap between imprecise manual roller clamps and high-cost electronic syringe or volumetric infusion pumps. By incorporating a micro-machined, logarithmic helical fluid channel within a high-clarity polycarbonate housing, our dial flow controller provides a continuous, linear control range from 5 mL/h to 250 mL/h.
Equipped with an ergonomic, tactile adjustment wheel and a dual silicone sealing gasket, the device eliminates line constriction variability. As fluid enters the dial regulator, it flows through a precision channel whose effective cross-sectional length is varied by rotating the external dial face. This creates predictable fluid resistance according to the Poiseuille Law governing laminar flow:
where Q is volumetric flow rate, r is channel radius, ΔP is hydrostatic head pressure differential, η is fluid dynamic viscosity, and L is the active micro-channel length controlled by the user dial position. By controlling L precisely through tactile index notches, flow rate accuracy is stabilized within ±10% to ±15% across standard crystalloid intravenous solutions under fixed head heights (approx. 80–100 cm above patient heart level).
Manufactured under stringent ISO 13485 cleanroom protocols, our Dial Flow Regulators are available as standalone IV extension sets or fully integrated within IV Infusion and Measured Volume Burette Sets.
Standalone IV extension set featuring a dual-scale calibrated dial (5-250 mL/h), kink-resistant DEHP-free PVC extension line, and male/female ISO 80369-7 Luer locks.

Comprehensive technical specifications for procurement officers, biomedical engineers, and quality assurance evaluators.
As global healthcare systems face economic pressures, sustainability mandates, and heightened safety regulations, the market for mechanical flow controllers is experiencing significant evolutionary shifts.
Health authorities across the EU (MDR), North America (FDA), and East Asia are enforcing strict bans on DEHP [Di(2-ethylhexyl)phthalate] and other harmful plasticizers in medical infusion lines due to endocrine-disrupting risks. Global healthcare procurement is transitioning 100% toward TOTM-plasticized PVC, Polyurethane (PU), and bio-based thermoplastic elastomers. Lars Medicare leads this transition by offering completely DEHP-free and phthalate-free Dial Flow Regulators with validated ISO 10993 biocompatibility compliance.
Hospitals in emerging markets and homecare provider networks are increasingly decentralizing IV administration. Electronic infusion pumps require significant capital expenditure, continuous calibration, electrical power, and intensive nursing maintenance. Dial Flow Regulators deliver reliable, precise fluid delivery at a fraction of the cost—making them the primary choice for emergency transport, post-operative recovery, ambulatory care, and field hospitals.
To reduce hospital-acquired bloodstream infections (CRBSIs) and environmental contamination, modern Dial Flow Regulators are being integrated with closed-system transfer devices (CSTDs) and needle-free valve ports. Lars Medicare's OEM line integrates pre-assembled swappable needle-free connectors, ensuring clinicians can administer push medications without compromising the calibrated drip rate or exposing line lumens to air contaminants.
Traceability standards (GS1 Unique Device Identification / UDI) are becoming mandatory for hospital supply chain inventory control. Procurement directors now mandate medical packaging that includes machine-readable DataMatrix codes, recyclable peel-open blister paper, and minimized plastic mass. Lars Medicare provides UDI-ready private label packaging solutions engineered for automated hospital logistics systems.

Unlike trading intermediaries, every Dial Flow Regulator is designed, moulded, assembled, and sterilized within our state-of-the-art facility in Sonepat, Haryana, India.
In-depth, expert responses addressing clinical mechanics, regulatory compliance, OEM customization, and supply chain logistics for Dial Flow Regulators.
An electronic infusion pump provides mechanical pumping action with operational accuracy around ±5%. However, pumps require continuous electrical supply, regular maintenance, costly specialized pump tubing cassettes, and substantial capital investment (often $1,500–$3,000 per pump unit). A Dial Flow Regulator operates via gravity, utilizing a calibrated helical micro-channel to achieve continuous flow rates between 5 mL/h and 250 mL/h with a clinical accuracy of ±10% to ±15%.
For routine hydration, antibiotic administration, post-operative analgesia, and general IV therapies, the Dial Flow Regulator provides a highly safe, reliable, and cost-effective solution (costing a fraction of a dollar per unit) while freeing up electronic pumps for critical intensive care applications.
Flow rate deviations in gravity-driven infusion sets are primarily driven by four variables: variations in fluid head height (hydrostatic pressure), fluid temperature/viscosity changes, patient venous backpressure fluctuations, and physical tubing constriction creep. Standard manual roller clamps squeeze soft PVC tubing, causing cold-flow deformation that leads to flow decay over time.
Lars Medicare eliminates tubing creep by engineering the flow channel inside a rigid, injection-moulded polycarbonate housing with a liquid silicone sealing gasket. The internal lumen width remains completely fixed at any given dial setting. Furthermore, our clear dial face includes tactile indexing notches that lock the dial in place, preventing accidental shifting during patient movement.
Yes. Lars Medicare Dial Flow Regulators and extension sets are fully compliant with EU Regulation 2017/745 (MDR), ISO 13485:2016 standards, and international medical device directives. We formulate our tubing using 100% DEHP-free and phthalate-free medical-grade PVC plasticized with TOTM (Tri-Octyl Trimellitate) or Polyurethane (PU).
Each production lot undergoes comprehensive ISO 10993 biocompatibility testing, including cytotoxicity, systemic toxicity, hemocompatibility, and skin sensitization testing. Full material safety data sheets (MSDS) and certificates of compliance are provided with export dossiers.
As a direct OEM manufacturer, Lars Medicare provides end-to-end customization for medical brand owners, national tender suppliers, and healthcare distributors. OEM options include:
Our sterilisation processes are validated strictly in accordance with ISO 11135 (Sterilization of health-care products — Ethylene oxide). Dial Flow Regulators undergo a validated 100% EO gas cycle within automated sterilisation chambers at our Sonepat manufacturing complex.
Each batch is monitored using chemical indicators, biological indicators (Bacillus atrophaeus spores), and residual gas analysis via Gas Chromatography. We guarantee residual EO and Ethylene Chlorohydrin (ECH) levels well below the strict limits defined by ISO 10993-7 (<1 ppm), ensuring immediate bio-safety for clinical use. Sterilisation certificates are issued for every export container.
For standard Lars Medicare branded or neutral-packaged Dial Flow Regulators, our standard minimum order quantity starts at 5,000 units (or 1 mixed pallet). For customized OEM private-label orders involving specialized printing and branded packaging, the typical MOQ is 20,000 units per SKU.
Production lead time for repeat stock catalogue orders is typically 3 to 4 weeks. First-time private-label programs require 5 to 6 weeks to finalize artwork proofs, custom tool calibration, sterilisation cycle validation, and pre-shipment quality assurance release.
Dial Flow Regulators are specifically calibrated for aqueous, low-viscosity intravenous fluids such as 0.9% Normal Saline, 5% Dextrose, Ringer's Lactate, and diluted electrolyte or antibiotic solutions. They are not recommended for blood components, packed red blood cells (PRBCs), plasma, or lipid emulsions.
High-viscosity fluids alter internal fluid friction, reducing actual flow rate relative to the printed dial scale. Additionally, the micro-channel dimensions may cause shear stress on red blood cells (hemolysis). For blood products, Lars Medicare supplies dedicated Blood Transfusion Sets equipped with 200-micron filters and high-bore roller clamps.
