Drick DRK005 Touchscreen Syringe Sliding Force Tester

Overview

The Drick DRK005 Touchscreen Syringe Sliding Force Tester is a precision-engineered mechanical testing instrument designed to quantify the sliding force characteristics of single-use medical syringes in accordance with internationally harmonized regulatory standards. It operates on the principle of controlled axial displacement under load, measuring the dynamic and static frictional forces encountered during plunger movement within the barrel—critical parameters directly linked to clinical usability, patient safety, and device reliability. The system implements a motor-driven linear actuator coupled with high-fidelity load cell sensing and real-time position feedback, enabling traceable quantification of break-loose force (start-up force), average gliding force, peak resistance force, and force variability over defined stroke lengths. Its architecture complies with the fundamental metrological requirements for medical device verification under ISO/IEC 17025-accredited laboratory environments.

Key Features

• ARM-based embedded control system with real-time multitasking capability, ensuring deterministic response and minimal latency during force acquisition and motion control.
• 800 × 480 high-contrast color TFT touchscreen interface with intuitive graphical navigation—supporting both English and Chinese language modes and dual-unit display (N, kgf, lbf) for global operational flexibility.
• High-resolution force measurement: 1 part in 200,000 full-scale resolution (7-digit display including decimal point); force accuracy better than ±0.3% of reading across the calibrated range.
• Sampling frequency up to 200 Hz, capturing transient force events such as plunger “stick-slip” phenomena with sufficient temporal fidelity for waveform analysis.
• Displacement measurement accuracy: ±0.5% of full scale; speed control accuracy: ±1% of setpoint—enabling reproducible test profiles across varying syringe capacities (from 0.3 mL to 60 mL).
• Dual-layer protection architecture: hardware interlocks (limit switches, overload cutoff) and software-based fail-safe logic (force threshold abort, position error detection, emergency stop escalation).
• User-level access control (up to 10 configurable accounts) with role-based permissions—supports audit-ready operation in GLP/GMP-regulated settings when paired with optional electronic signature modules.

Sample Compatibility & Compliance

The DRK005 is validated for testing all standard Luer-lock and Luer-slip syringes compliant with ISO 7886-1:2017 (Syringes for medical use — Part 1: Syringes for single use, sterile) and ISO 8537:2016 (Insulin injection systems for medical use). It fully supports GB 15810–2019 (Chinese national standard for sterile single-use syringes) and YY/T 0497–2018 (Chinese industry standard for sterile insulin syringes). Test height is programmable per nominal syringe volume or user-defined stroke length, accommodating variations in barrel geometry and plunger travel. All calibration certificates are traceable to NIM (National Institute of Metrology, China) or equivalent national metrology institutes via documented chain-of-custody.

Software & Data Management

The DRK005 includes embedded firmware with built-in data logging, curve visualization (force vs. displacement), and automated calculation of critical metrics: start-up force (break-loose), mean gliding force, maximum resistance force, standard deviation, coefficient of variation (CV%), and statistical summary per test group. Optional PC-based upper-level software enables CSV/XLSX export, comparative trend analysis across batches, PDF report generation with digital signature fields, and integration into LIMS environments. Audit trail functionality—including operator ID, timestamp, parameter changes, and result modifications—is available upon activation of user management and electronic record modules, aligning with FDA 21 CFR Part 11 compliance prerequisites for regulated laboratories.

Applications

• Quality control release testing of syringe assemblies prior to sterilization and packaging.
• Design verification and validation (V&V) of new syringe platforms, including low-friction coatings (e.g., silicone oil lubrication), polymer barrel formulations, and plunger elastomer compatibility.
• Stability studies assessing force profile degradation after accelerated aging (e.g., 40°C/75% RH for 3 months).
• Root cause analysis of clinical complaints related to excessive plunger resistance or inconsistent delivery force.
• Supplier qualification and incoming material inspection for syringe components (barrels, plungers, gaskets).
• Regulatory submission support for ISO 13485-certified manufacturers seeking CE Marking or FDA 510(k) clearance.

FAQ

What standards does the DRK005 comply with?
The DRK005 is configured and validated to meet ISO 7886-1:2017, ISO 8537:2016, GB 15810–2019, and YY/T 0497–2018. Calibration and performance verification protocols follow ISO/IEC 17025 guidelines.
Can the DRK005 export raw test data for external statistical analysis?
Yes—via USB interface or optional Ethernet connectivity, the instrument supports export of time-stamped force/displacement datasets in CSV format, compatible with MATLAB, JMP, Minitab, and other statistical software packages.
Is firmware upgrade supported remotely?
Firmware updates are delivered via encrypted USB drive with version-controlled release notes and change logs. Remote update over network is not enabled by default for security and regulatory integrity reasons.
Does the system support multi-user audit trails for GMP environments?
When the optional User Management Module is activated, the DRK005 records operator login/logout events, test parameter modifications, and result approvals with immutable timestamps—fulfilling core ALCOA+ data integrity principles.
What maintenance is required to ensure long-term measurement stability?
Annual recalibration by an accredited metrology lab is recommended. Routine verification using certified reference load cells and displacement gauges should be performed daily or per shift, per internal SOPs aligned with ISO 13485 clause 7.6.
