The Usage Principle of Disposable Surgical Mask

Disposable surgical mask products are used for clinical personnel to wear in the non-invasive operation process, covering the mouth, nose and jaw of the user, to prevent the direct passage of pathogens, microorganisms, particles and other physical barriers.
Disposable surgical mask is self-absorption filter mask, the principle of work is to make the air containing harmful substances through the filter material of the mask to be inhaled or exhaled.There are four main filtration mechanisms of mask filter

Schematic diagram of filtration mechanism of filter material fiber
1. Diffusion deposition: the Brownian motion of particles spreads to the filter fiber and is absorbed by the molecular gravity.
2. Interception deposition: larger particles moving with the airflow are trapped by the mechanical filtration of the filtration material.
3. Inertia deposition: when particles pass through the curved mesh channel of the filter material, the particles break away from the airflow due to the inertia and hit the filter fiber, and are trapped by the molecular gravity.
Electrostatic attraction deposition: deposition of particles by electrostatic action of the filtered fiber.

Disposable surgical mask is composed of SMS three-layer structure, two layers of non-woven fabric fiber diameter is relatively thick, about 20 microns, plays a role in supporting the entire mask structure, the middle melt spray layer fiber is relatively thin, about 2 microns, can filter 95% of bacteria, and SMS three-layer structure has a good ventilation effect.

Disposable medical mask products are composed of medical non-woven fabrics, ear hangers and nose clips.

Reference Standard For Seal Verification of Sterilization Pouches For Medical Devices

With the increasing demand for  sterilization pouches  of medical devices, quality and safety inspection have become more and more stringent. sterilization pouches of medical devices (blister box +  tyvek roll  material,  sterilization paper bag , etc.) as a form of packaging directly in contact with the device and used to block microorganisms. No matter what form of packaging, it has two characteristics, which can meet the sterilization operation and remain sterile until the transportation conditions are used. Therefore, relevant departments began to focus on the review requirements of sterile packaging and make specific requirements for its performance and quality.   As we all know, GB/ t19633-2005 "packaging of ultimately sterilized medical devices" is one of the authoritative standards in the current sterile packaging standards. It is equivalent to iso11607-2003 "packaging of ultimately sterilized medical devices". Clarify the basic performance req...

If You Think Your Pouch is Just a Pouch, Wait Until You Read This

  Do you know what self sealing sterilization pouches are? If not, then read on to learn more about these amazing products. A self-sealing sterilization pouch is a bag that can be sealed and opened with one hand and contains an atmosphere that will destroy bacteria and other microorganisms in the bag's contents.   Self seal sterilization pouches   have been used for decades in hospitals worldwide because they offer excellent protection against contamination of medical instruments, surgical equipment, or pharmaceuticals during transport or storage. When self sealing sterilization pouches are used to package medical devices or pharmaceuticals, the self seal sterilization pouch provides a barrier that protects these products against moisture and contamination during shipping. This helps ensure that when your customers use them in their procedures, they will be safe for patient care. What do you truly understand about the sterilization pouches you use? What should you be awar...
