Introduction of Disposable Medical(Surgical) Mask

Disposable medical(surgical)mask can block particles larger than 4 microns in diameter, and tests conducted in the respirator seal laboratory in a hospital setting showed that they had a transmittance of 18.3 percent for particles of 0.3 microns, according to general medical(surgical)standards.

Disposable medical(surgical)masks are mainly used in medical(surgical)clinics, laboratories, operating rooms and other high-demand medical(surgical)environment, the safety factor is relatively high, suitable for the basic protection of medical(surgical)personnel or related personnel. In the process of medical(surgical)invasive operation, the spillage of blood, body fluid and spatter plays a protective role. It also prevents the exhalation of microbes by medical(surgical)personnel, posing a threat to patients undergoing surgery.

Disposable medical(surgical)mask have a strong resistance to bacteria and viruses. In daily life, they can be used to prevent the spread of influenza, respiratory diseases and other infectious diseases. They can also prevent patients from spreading viruses to others.

Typically made of nonwoven materials, including filter layers, mask straps, and nose clips. The standard medical(surgical)mask has three layers. The outer layer is waterproof to prevent droplets from entering the mask. The middle layer has filtration function, which can block 5 ~ 5 ~ m particles of >90%. The inner layer of the near muzzle is used for moisture absorption.

The material of medical(surgical)mask

Disposable medical(surgical)mask use polypropylene as the main raw material. The fiber diameter can reach 0.5-10 microns. These ultrafine fibers with unique capillary structure increase the number of fibers per unit area and surface area, so that melt-spray cloth has good filtering, shielding, insulation and oil absorption.

The mask is made of non-flammable material and burns after leaving the flame <5s; For masks sterilized with ethylene oxide, the residual amount of ethylene oxide should be less than 10 g/g. The primary skin irritation index of the mask material should be no more than 0.4, and there should be no allergic reaction.

When wearing medical(surgical)masks, appropriate levels should be selected according to the transmission type and risk of pollutants, not too high or too low. medical(surgical)disposable medical(surgical)mask can cut off most of the bacteria and some viruses, can prevent medical(surgical)staff infected, and can prevent the spread of medical(surgical)personnel to the outside world pathogenic bacteria, so is suitable for clinical medical(surgical)staff basic protection, that is used for clinical medical(surgical)staff to wear in the process of invasive operation, for in patients undergoing treatment and the implementation and operation of the medical(surgical)staff to provide protection, prevent the spread of blood, body fluids, and splash.

During the epidemic of infectious diseases, disposable medical(surgical)mask can effectively prevent the spread of pathogenic bacteria and play a preventive and protective role for all kinds of personnel in places with relatively dense personnel, such as outpatient guidance or consultation, elevator, emergency, etc.


Wearing a medical(surgical)mask correctly is an effective means to prevent the spread of respiratory secretions. The wearing method is as follows:

(1) clean your hands before wearing the mask, avoid touching the inner side of the mask during wearing the mask, and reduce the possibility of contamination of the mask;

(2) when wearing the mask, distinguish the inside and outside, the top and bottom of the mask, the light-colored face is inside, the dark-colored face is facing outside, the metal strip (nose clip) at one end is the top of the mask, fully unfold the folded face;

(3) cover the mouth, nose and jaw with one side of the nose clip upward, adjust the lower end of the mask to the appropriate position of the jaw, attach the elastic bands on both sides to the ears or tie the binding bands on both ends to the back of the head, then press the nose clip to make the mask completely fit the face.

In daily life and normal social activities, the healthy public is not recommended to wear masks. Personal protection should be provided by wearing a mask if contact with an epidemic patient is required, or if the patient is in a densely populated and unventilated place for an extended period of time.

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 requirements of s

What is Self Seal Sterilization Pouches

  self seal sterilization pouches  is carried out in hospitals and medical or surgical sterilization manufacturing plants. Most packaging must be sterile when delivered to the end user. Medical self seal sterilization pouches provides protective envelopes for sterilization to protect against sterilization during disinfection, transportation, storage and delivery to the final home. Medical self seal sterilization pouches can assemble and secure several sterilization items required for a given surgical procedure and be ready for operation.   The term "sterilization" covers a wide range of products. A cotton ball, a cotton swab, and a tongue spatula are examples of "treatable products." Use them once and throw them away." Use once is not a synonym for cheap. Some very expensive sterilizations, such as dialysis filters, are themselves too fragile to be cleaned and reused after sterilization. To save costs, reuse is desirable. Most medical sterilization, such as sci

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 aware of? What
