About Me

A surgical mask, also known by other names such as a <a
href="http://www.snxamedical.com/face-mask/medical-face-
mask/" target="_self">medical face mask or procedure
mask, is a personal protective equipment used by healthcare
professionals that serves as a mechanical barrier that
interferes with direct airflow in and out of respiratory
orifices (i.e. nose and mouth). This helps reduce airborne
transmission of pathogens and other aerosolized contaminants
between the wearer and nearby people via respiratory droplets
ejected when sneezing, coughing, forceful expiration or
unintentionally spitting when talking, etc. Surgical masks
may be labeled as surgical, isolation, dental or medical
procedure masks. The dust blocking efficiency of <a
href="http://www.snxamedical.com/face-mask/"
target="_self">face mask is based on its blocking
efficiency against fine dust, especially respiratory dust
below 2.5 microns. Because the dust with this particle size
can directly enter the alveoli, it has the greatest impact on
human health. The dust blocking principle of gauze mask is
mechanical filtration, that is, when the dust collides with
the gauze, it passes through layers of barrier to block some
large particles of dust in the sand cloth. For some fine
dust, especially dust less than 2.5 microns, it will pass
through the mesh of gauze and enter the respiratory system.
The dust mask is composed of filter material activated carbon
fiber felt pad or non-woven fabric. Those respiratory dust
less than 2.5 microns are isolated in the process of passing
through this filter material to filter air.

The anti side leakage design of mask is to prevent air
from being inhaled through the gap between mask and human
face without filtering. Air is like water flow. It flows to
where the resistance is small. When the shape of the mask is
not close to the face, the dangerous objects in the air will
leak from the non close place and enter the human respiratory
tract. Well, even if you choose a mask with the best filter
material. Nor can it protect your health. Many foreign
regulations and standards stipulate that workers should
regularly test the tightness of masks. The purpose is to
ensure that workers choose masks of appropriate size and wear
masks according to the correct steps. For the filter material
of a good protective mask, the following three conditions
should be met: first, the filter efficiency is high when the
mask is well sealed with the user's face, second, the
respiratory resistance is small, and third, the user feels
comfortable. There are a variety of materials such as
ordinary woven fabrics and animal dust masks. What is very
popular in the national standard is a kind of activated
carbon felt material. The structure of gauze mask has poor
tightness with human face. Many fine particles that do great
harm to us will enter the respiratory tract and lungs through
the gap between mask and face. Its filter material is
generally some mechanical fabrics. The only way to achieve
high dust prevention efficiency is to increase the thickness,
and the negative effect of increasing the thickness is to
make users feel great respiratory resistance and
uncomfortable. The electrostatic treated non-woven fabric can
not only block large dust particles, but also the
electrostatic charge attached to its surface can adsorb the
fine dust through electrostatic attraction, so as to achieve
high dust prevention efficiency. The thickness of the filter
material is very thin, which greatly reduces the respiratory
resistance of users and feels comfortable, so as to meet the
three necessary conditions of good filter material mentioned
above. With good filter material and scientifically designed
mask structure, an efficient and high-quality mask is formed.

<a href="http://www.snxamedical.com/face-
mask/disposable-face-mask/" target="_self">Disposable face
masks are made of more than three layers of 28g non-woven
fabrics; The bridge of the nose is made of environment-
friendly all plastic strip, which does not contain any metal.
It is equipped with breathable and comfortable. It is
especially suitable for electronic factories and daily life.
Disposable mask (medical surgical mask) can prevent
respiratory tract infection to a certain extent, but can not
prevent haze. When purchasing, it should be noted that the
mask with the words "medical surgical mask" clearly
marked on the outer package should be selected. Disposable
three-layer mask is made of two layers of non-woven fabric
and filter paper; The disposable three-layer mask is made of
two layers of fiber non-woven fabric professionally used for
medical and health, with an additional layer in the middle.
The filter spray cloth with more than 99% bacteria prevention
is welded by ultrasonic. The bridge of the nose adopts
environment-friendly all plastic strip, which does not
contain any metal. It is equipped with steam permeability and
comfortable. The filtering effect of b.f.e is up to 99%,
especially suitable for electronic factories; The disposable
activated carbon mask is made of 28g non-woven fabric on the
surface and 99% bacteria proof filter paper on the first
layer in the middle, which plays a role in preventing
bacteria and virus harm; The second layer in the middle is
made of new high-efficiency adsorption and filtration
materials - activated carbon fiber and activated carbon
cloth, which has the effects of anti-virus, anti odor,
bacterial filtration and dust prevention; The disposable mask
is made of environment-friendly full plastic nose bar, and
the nose clip design can be adjusted most comfortably
according to different face shapes. The inner covering
ultrasonic spot welding is selected, and the ear belt can be
very firm and not easy to fall.

<a href="http://www.snxamedical.com/gloves-
series/protective-gloves/" target="_self">Protective gloves
are used to protect hands from injury. In medical
treatment, it is mainly used for medical examination,
isolation and protection. There are mainly medical
examination gloves, sterile medical gloves, medical X-ray
protective gloves, etc. There are many kinds of protective
gloves. The medical protective <a
href="http://www.snxamedical.com/gloves-series/"
target="_self">gloves series include inspection gloves,
sterile <a href="http://www.snxamedical.com/gloves-
series/medical-gloves/" target="_self">medical gloves,
medical X-ray protective gloves, etc. Sterile medical gloves
belong to medical polymer materials and products. Ordinary
sterile medical rubber gloves are used in the hospital
operating room. The disadvantages of these gloves include:
different production processes and too little talc powder
coating; It is laborious for doctors with large hands; Most
preoperative hand washing do not use alcohol to soak, but use
disinfectant to smear the arm. After applying the
disinfectant, the arm becomes astringent. When wearing
gloves, the cuff on the back of the hand is easy to reverse,
so that the back of the glove is in contact with the skin,
which may cause pollution and fail to meet the sterility
requirements.

The types of <a
href="http://www.snxamedical.com/protective-clothes/"
target="_self">protective clothes include fire protection
clothing, industrial protective clothing, medical protective
clothing, military protective clothing and protective
clothing for special groups. Protective clothing is mainly
used in fire protection, military industry, shipping,
petroleum, chemical industry, painting, cleaning and
disinfection, laboratory and other industries and
departments. According to the protective function, it is
divided into health protective clothing, such as radiation
proof clothing, cold proof clothing, heat insulation clothing
and antibacterial clothing; Safety protective clothing, such
as flame retardant clothing, flame retardant protective
clothing, arc protective clothing, anti-static clothing,
bulletproof clothing, stab proof clothing, aerospace
clothing, diving clothing, acid proof clothing and insect
proof clothing; Work clothes to keep the wearer healthy, such
as oil proof clothes, dust-proof clothes and water repellent
clothes. The structure of protective clothing has the
characteristics of anti permeability, good air permeability,
high strength and high hydrostatic pressure resistance. It is
mainly used in industrial, electronic, medical, chemical and
bacterial infection prevention environments. In addition to
meeting the wear requirements of high strength and wear
resistance, it often varies due to different protection
purposes and protection principles, from natural materials
such as cotton, wool, silk and lead, synthetic materials such
as rubber, plastic, resin and synthetic fiber, to
contemporary new functional materials and composites, such as
impact resistant Para aromatic polyamide and high strength
and high modulus polyethylene fiber products, oil repellent
fluorine-containing compounds and radiation resistant
polyimide fibers, Antistatic agglomerated acrylic fiber,
complex copper fiber, antibacterial fiber and related odor
resistant finished fabrics.

<a href="http://www.snxamedical.com/syringe/"
target="_self">Syringe is a common medical appliance. As
early as the 15th century, the Italian cartiner put forward
the principle of syringe. It mainly uses a needle to extract
or inject gas or liquid. It can also be used to inject
medical equipment, containers, such as scientific instruments
in some chromatography through rubber diaphragms.
