Bacterial and Viral Filter Without Sampling Port

Core Product Overview

The Bacterial and Viral Filter Without Sampling Port is a disposable medical consumable. Its core function is to block the transmission of bacteria and viruses during mechanical ventilation, preventing cross-infection. It is often used with ventilators, anesthesia machines, and respirators, and is particularly suitable for anesthetized surgical patients—making it an indispensable protective consumable in clinical respiratory support therapy. By filtering droplets, particles, bacteria, and viruses from oxygen and anesthetic gases, the product not only protects patients' lungs from infection but also reduces contamination of ventilator circuits, providing dual protection for medical operations and meeting various routine clinical respiratory treatment needs.

Product Structure & Working Principle

With a simple and practical structural design, the Bacterial and Viral Filter Without Sampling Port consists of three parts: a plastic-molded bottom cover, a top cover, and an intermediate filter medium, ensuring reliable overall sealing performance. During use, it is installed between the endotracheal tube and the ventilator circuit to form a protective barrier. When gas flows through the filter, the intermediate filter medium efficiently traps contaminants such as bacteria, viruses, and foreign particles, achieving a filtration efficiency of up to 99.99%. Meanwhile, the filter retains part of the temperature and humidity from the patient's exhaled air, maintaining a stable temperature and humidity environment in the airway, avoiding irritation from dry gas, and improving patient breathing comfort.

Core Product Features

Low-Resistance Ventilation: Low breathing resistance does not add extra burden to patients' breathing. It also effectively reduces patients' inhalation of their own exhaled air, ensuring smooth ventilation;

High-Efficiency Filtration: 99.99% filtration efficiency for bacteria, viruses, and foreign particles, firmly blocking pathogen transmission paths and reducing infection risks;

Temperature & Humidity Preservation: Maintains airway temperature and humidity, preventing dry gas from damaging the respiratory mucosa and improving patient comfort during ventilation therapy;

Compact & Lightweight: Small in size and light in weight, it does not affect equipment connection or patient movement, adapting to various clinical operation scenarios;

Safe Material: Made of new medical-grade ABS material with good stability and corrosion resistance, no odor, and no harmful substances for safe use;

Focus on Basic Protection: No sampling port design, concentrating on core filtration functions with a simpler structure, reducing use and maintenance costs.

Product Specifications

Material: New medical-grade materials, core components made of medical-grade ABS, filter medium suitable for medical protection needs;

Color: Transparent body for intuitive observation of internal status, facilitating clinical inspection of normal usage;

Interface Specifications: Two optional adapter interfaces: 22mm ID/15mm OD and 22mm OD/15mm ID, compatible with mainstream ventilators, anesthesia machines, and breathing circuits;

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

Application Scenarios

Specifically designed for routine clinical scenarios that do not require breathing gas sampling and testing, it has a wide adaptation range. For example, hospital routine mechanical ventilation treatment scenarios and basic oxygen supply treatment scenarios, covering the basic protection needs of multiple departments such as Respiratory Medicine, Anesthesiology, and Intensive Care Unit (ICU). No additional sampling-related accessories are required, and it can be used immediately, adapting to clinical routine diagnosis and treatment processes.

VI. Simple Usage Instructions

Take out the individually packaged Bacterial and Viral Filter Without Sampling Port, check if the packaging is intact, and open it only if there is no damage;

Firmly connect the air inlet of the filter to the gas outlet of the ventilator or anesthesia machine, ensuring a tight seal without air leakage;

Connect the other end of the filter to the breathing circuit, confirming all connections are tight and secure;

After connection, start the relevant equipment to conduct ventilation or anesthesia treatment. The product is disposable—dispose of it in accordance with medical waste regulations after treatment.

With its high-efficiency filtration performance, convenient operation, and reliable safety, this product has become a high-quality choice for basic protection in clinical respiratory therapy. It not only meets the core needs of medical operations but also provides dual protection for patients and medical staff.
