Bacterial and Viral Filter With Sampling Port

Core Product Overview

The Bacterial and Viral Filter With Sampling Port is a disposable medical consumable focusing on infection protection and gas sampling during mechanical ventilation. Often used with ventilators, anesthesia machines, and respirators, it is a practical tool balancing protection and monitoring in clinical diagnosis and treatment. Composed of a plastic-molded bottom cover, top cover, and intermediate filter medium, it is primarily applied in anesthetic scenarios for surgical patients. Installed between the endotracheal tube and ventilator circuit, it not only filters bacteria, viruses, droplets, and particles from oxygen and anesthetic gases—preventing cross-infection caused by anesthesia ventilators and protecting patients' lungs—but also enables gas detection through its dedicated sampling port without interrupting the protection process, perfectly meeting clinical monitoring needs.

Core Product Features

Low Breathing Resistance: Does not add extra burden to patients' breathing during ventilation. It also effectively reduces patients' inhalation of their own exhaled air, improving breathing comfort without affecting the normal rhythm of mechanical ventilation;

Outstanding Filtration Efficiency: Achieves up to 99.99% filtration efficiency for external foreign particles and bacteria, firmly blocking pathogenic microorganisms, reducing infection risks, and building a safety barrier for patients and medical staff;

Maintains Airway Condition: Retains airway temperature and humidity during ventilation, avoiding dry gas irritation and ensuring stable airway function;

Compact & Lightweight: Small in size and light in weight, it takes up no extra space when connected between equipment and pipelines, without interfering with clinical operations or patient position adjustments;

Practical Sampling Function: The sampling port allows easy connection to sampling devices, meeting clinical needs for respiratory gas composition monitoring and microbial detection. Additionally, this port can connect to oxygen tubes for dual-purpose use, adapting to more clinical scenarios;

Safe & Durable Material: Made of medical-grade PP material, featuring light weight, aging resistance, and easy processing. It poses no safety hazards when in contact with breathing gases and meets strict medical consumable standards.

Product Specifications and Parameters

Material: Medical-grade PP

Color: White

Interface Specifications: 22M-22F/15M, compatible with mainstream ventilators, anesthesia machines, and breathing circuits, ensuring firm connection and leak resistance;

Packaging Method: Individual paper-plastic bag packaging for single-person single-use, avoiding contamination during storage and transportation and ensuring hygienic use.

IV. Application Scenarios

Specifically designed for special clinical scenarios requiring real-time monitoring of respiratory gas composition and microbial detection. Unlike ordinary filters, it can complete gas sampling without interrupting filtration protection, eliminating the need for repeated equipment disassembly. It ensures continuous protection while improving detection efficiency, adapting to the special diagnosis and treatment needs of hospital departments such as Intensive Care Unit (ICU), Respiratory Medicine, Emergency Department, and Anesthesiology.

Common Uses

ICU Critical Care: Suitable for critically ill patients on mechanical ventilation. It filters pathogenic microorganisms in the circuit and provides real-time monitoring of respiratory gas composition through the sampling port, offering data support for disease assessment and reducing infection risks;

Respiratory Function Evaluation: For patients with chronic respiratory failure, it collects respiratory gas samples for testing while ensuring ventilation protection, helping doctors accurately assess respiratory function and adjust treatment plans;

Emergency Critical Rescue: During the rescue of acutely critically ill patients, it enables rapid connection to sampling devices for gas collection without delaying ventilation treatment or infection protection, saving valuable rescue time;

Precision Anesthesia in Anesthesiology: During surgery, it filters microorganisms in the anesthesia machine circuit to reduce the risk of postoperative pulmonary infection. Meanwhile, it monitors exhaled anesthetic gas concentration through the sampling port, assisting doctors in precise anesthesia dosage adjustment and ensuring surgical safety.

Usage Necessity & Precautions

Usage Necessity

When using ventilators clinically, exhaled gas from patients may contain a large number of pathogenic bacteria, which not only pollute the ward environment but also easily cause hospital-acquired cross-infection, endangering the health of medical staff. Installing the Bacterial and Viral Filter With Sampling Port at the ventilator's expiratory end can effectively trap these pathogenic microorganisms, preventing cross-infection at the source.

Precautions

The product is disposable and must be replaced promptly after use. Do not reuse it to avoid protection failure due to saturated or contaminated filter medium;

When connecting sampling devices or oxygen tubes, ensure tight interface connection to prevent gas leakage that may affect protection effectiveness or detection data accuracy.

With its integrated "protection + sampling" design, high filtration efficiency, and multi-scenario adaptability, this product effectively meets the dual clinical needs of precise diagnosis/treatment and infection prevention. It is an excellent choice for medical institutions to improve the safety and convenience of diagnosis and treatment.
