Electric Suction Unit DDXYQ by Beijing Manufacturer

Overview

The Electric Suction Unit DDXYQ is an oil-free, hospital-grade vacuum aspiration system engineered for reliable and contamination-controlled fluid removal in clinical, surgical, and emergency care environments. It operates on the principle of positive displacement vacuum generation via a sealed, maintenance-free oil-free rotary vane pump—eliminating oil mist emission and ensuring compliance with ISO 13485–aligned cleanroom and infection control requirements. Designed for intermittent loading under continuous operational duty cycles, the unit delivers stable negative pressure across its full adjustment range (0.02–0.09 MPa), supporting diverse suction demands—from low-pressure wound drainage to high-flow oral/airway aspiration. Its structural integration—featuring direct-mount collection bottles, overflow-sensing circuitry, and dual-mode actuation—reflects ergonomic and safety-first engineering aligned with IEC 60601-1 essential performance criteria.

Key Features

• Oil-free vacuum pump with ≥30 L/min free-air flow rate and ≥0.09 MPa ultimate vacuum—ensuring rapid evacuation without hydrocarbon contamination or scheduled lubrication.
• Two 2500 mL rigid polypropylene collection bottles mounted directly onto integrated chassis trays—enabling rapid deployment, transport stability, and simplified bottle exchange.
• Sealed, O-ring-equipped bottle caps with large-diameter access ports—facilitating efficient cleaning, residue removal, and secure resealing during high-volume use.
• Automatic liquid overflow cutoff mechanism—detecting rising fluid levels in real time to interrupt vacuum path before liquid ingress into the pump chamber.
• Transparent, non-toxic PVC suction tubing (ISO 10993–certified biocompatibility)—allowing visual confirmation of fluid type, volume, and flow continuity during procedure execution.
• Integrated bacterial air filter (≥0.2 µm pore size) installed at exhaust outlet—reducing aerosolized microbial load in ambient clinical air per CDC and WHO airborne pathogen mitigation guidelines.
• Dual-control interface: parallel-wired manual toggle switch and foot pedal—providing hands-free operation during sterile procedures while maintaining fail-safe redundancy.
• Acoustically damped enclosure yielding ≤60 dB(A) at 1 m distance—supporting quiet operation in shared treatment rooms, ICUs, and outpatient settings without auditory stress accumulation.

Sample Compatibility & Compliance

The DDXYQ accommodates standard medical-grade suction catheters (Fr 6–Fr 24), Yankauer tips, Poole suction devices, and endoscopic aspiration accessories. All wetted components—including bottle interiors, tubing connectors, and valve housings—are constructed from USP Class VI–compliant polymers resistant to common disinfectants (e.g., 70% ethanol, 0.5% sodium hypochlorite). The device conforms to GB 9706.1–2020 (equivalent to IEC 60601-1:2012+AMD1:2021), meets electromagnetic compatibility requirements per GB/T 18268.1–2010, and supports documentation traceability for GLP/GCP-aligned clinical trial deployments. While not FDA 510(k)-cleared, its design basis aligns with ASTM F2793 (Standard Specification for Suction Equipment Used in Health Care Facilities).

Software & Data Management

This unit operates as a standalone electromechanical system without embedded firmware or digital interfaces. All operational parameters—including vacuum setpoint, runtime duration, and activation mode—are manually configured and recorded externally via facility-maintained procedure logs. For institutions requiring audit-ready records, the DDXYQ integrates seamlessly with third-party electronic health record (EHR) systems through analog signal output modules (optional accessory), enabling timestamped event logging compatible with FDA 21 CFR Part 11–compliant validation protocols when paired with validated middleware.

Applications

• Operating room aspiration during general, orthopedic, and neurosurgical procedures.
• Emergency department airway management and gastric lavage.
• Wound care centers performing controlled negative-pressure therapy (NPWT) priming and drainage monitoring.
• Dental clinics utilizing high-volume evacuation (HVE) for aerosol reduction during ultrasonic scaling.
• Mobile medical units and field hospitals where portability, power resilience, and minimal maintenance are critical.

FAQ

Is the DDXYQ suitable for continuous 24/7 operation?
No—it is rated for intermittent loading under continuous duty cycle conditions per GB 9706.1, meaning it may operate for extended periods with periodic rest intervals; sustained uninterrupted use beyond manufacturer-specified thermal limits voids warranty and compromises pump longevity.
Can the unit be used with wall-mounted central vacuum systems?
No—the DDXYQ is a self-contained, electrically powered suction source and is not designed for integration with or backup to centralized vacuum infrastructure.
What sterilization methods are approved for the collection bottles?
Bottles may be autoclaved at 121 °C for 20 minutes (gravity displacement cycle); chemical sterilization using glutaraldehyde or hydrogen peroxide vapor is also validated per manufacturer’s IFU.
Does the device include pressure calibration certification?
Unit-level factory calibration is performed prior to shipment; users must conduct routine verification using NIST-traceable manometers at least quarterly per JCAHO EC.02.05.01 standards.
Is the foot pedal medically certified for use in sterile fields?
The pedal housing is IP54-rated and compatible with standard barrier drapes; however, sterility is maintained solely through external draping—not intrinsic device certification.
