A toolset designed for R&D engineers developing catheters: fluid dynamics calculations, shaft stiffness, unit conversions, material comparison. Built by Protomed engineers to support your design decisions.
Free and confidential tools — running in your browser, no data transmitted.
Enter your values, pick your materials or fluids, view results and graphs. Everything is pre-filled, sourced and verifiable in a few clicks — no need to rebuild your Excel sheets for every project.
Every value is sourced. Every formula is given, every calculation states its assumptions. No black box, no opaque proprietary model — you can challenge every number.
Protomed engineers shaped these tools to deliver the features they actually use on their own projects. Relevant inputs, useful answers.
Three coupled calculations on flow through a catheter: Hagen-Poiseuille (flow rate, pressure), Reynolds (regime), residual volume. Five fluid presets (saline, blood HCT 45%, Iopamidol 300, Iohexol 350, water) with published viscosities, plus an inverse mode to solve for a target flow rate.
Compute EI stiffness and transmission torque for a composite shaft (jacket + reinforcement + liner). 12 standard materials (Pebax MED range, Nylon 12, Pellethane, PEEK, PTFE, 316L stainless steel, nitinol). A/B comparison mode to evaluate two configurations side by side.
Real-time conversion between French (Fr), millimeters, inches and gauge. Logarithmic visual scale with 8 clinical references (30G insulin needle to 24 Fr drainage). Three reference tables for catheter sizes, guidewires (0.014"–0.038"), and ISO 9626 needles.
Matrix of 14 materials × 8 criteria: flexural modulus, Shore hardness, HDT, kink resistance, friction, fluid and sterilization compatibility, use segments. Four combinable filters (segment, stiffness, kink, sterilization) to isolate viable options under your project constraints.
When your questions extend beyond catheter design — accelerated ageing ASTM F1980, AQL sampling plans, V&V sample sizing ISO 16269-6, biocompatibility ISO 10993, sterilization compatibility — Protomed offers a complementary toolset focused on QA/RA and validation.
Subscribe to stay informed about updates, new features and upcoming tools added to the suite. No spam, no sales pitch — just product news.
A calculation you keep redoing that would deserve its own tool? A formula to correct, a value to challenge, a feature to add? Your feedback helps us shape future versions.
The tools on this page are decision-support tools. Values and results displayed are indicative orders of magnitude, sourced from public data, supplier datasheets, and technical literature. It is each user's responsibility to verify their relevance for their project, evaluate specific use conditions, and have any critical decision validated by a qualified evaluator.
These tools do not replace regulatory expertise, experimental validation, or original normative documentation. For contractual deliverables (test reports, design files, certified compliance curves), a study service is required.
