In early 2020, a novel coronavirus outbreak was identified by experts. Because there is no wonder drug at the moment, it has caused an alert at the beginning. Experts suggest that the public should stay at home to prevent virus transmission; when going out is necessary, wear a mask for self- protection. As the continuous of the epidemic, the demand for medical protective equipment has increased dramatically, resulting in insufficient supply and shortage. At the same time, the outbreak of the epidemic has given many medical supplies manufacturers a huge development opportunity. Most medical supplies manufacturers urgently called together the employees to increase production, in order to provide front-line medical staff with sufficient medical supplies and support the silent "war". Medical protective equipment, such as medical mask, protective clothing, medical gloves and other disposable medical equipment can effectively protect people from bacteria and viruses. As an important protective measure for medical staff and the public to avoid bacterial and virus infection, the quality of the product itself is crucial, and its manufacturers need to carry out strict quality control.
As a high-tech enterprise with more than 30 years of experience in research and development of testing instruments, Labthink responded swiftly to join the support for fighting the epidemic, we provide corresponding laboratory testing instruments for medical protective products manufacturers, medical equipment testing institutions and other involved institutions. . Relevant tests and testing instruments are introduced below.
Tests of Disposable Medical Protective Clothing
Medical protective clothing are wore by medical personnel (doctors, nurses, public health personnel, cleaners, etc.) and people entering specific areas (such as patients, hospital visitors, people entering the infected area, etc.). Its function is to isolate bacteria, harmful ultrafine dust, acid-base solution, electromagnetic radiation, etc., to ensure the safety of personnel and keep the environment clean.
Moisture permeability test of protective suit materials
According to GB 19082-2009 Technical Requirements for Single-use Protective Clothing For Medical Use, the moisture permeability of protective clothing material shall not be less than 2500g / (m2 ? g). Materials with good moisture permeability ensures the comfort of the protective clothing. The W3 / 062 Water Vapor Permeability Test System developed and produced by Labthink is a professional water vapor transmission rate (WVTR) test system based on the cup method (gravimetric method) test principle. It can be applied to the moisture permeability test of protective clothing materials. The instrument can test six test cups at the same time, which improves the test efficiency greatly. It is equipped with Labthink new generation of operation software, humanized design, and intelligent data processing system.
Tests of Breaking Strength and Elongation at Break
According to the standard, the breaking strength of the materials of protective clothing shall be no less than 45N, and the elongation at break shall be no less than 15%. It is recommended to use labthink XLW (PC) Intelligent Electronic Tensile Testing Machine for the tests. The testing machine can perform seven testing procedures, such as stretching, peeling and tearing. The 1000mm long stroke can meet the requirements of the testing of super deformation rate materials, multiple specifications of force sensors and seven test speeds allow users to perform tests under different test conditions.
Peel strength test of heat sealing tape for protective clothing
Heat sealing tape for protective clothing is the key material for the production of protective clothing. It is composed of base cloth and adhesive layer. It is pasted on the outer joint of protective clothing to prevent the penetration of blood, body fluid, bacteria and dust particles. Only by ensuring its high sealing strength, can the protective clothing perform its expected function. XLW (PC) Intelligent Electronic Tensile Testing Machine is a multi-functional material mechanics testing machine, which can perform the tests of tensile strength, breaking strength, elongation at break, peel strength and other items. Its high-precision sensors fit for carrying out the peel strength test of protective clothing sealing tape.
Tests of Ethylene Oxide Residue on Protective Clothing
The residual content of ethylene oxide in the protective clothing sterilized by ethylene oxide shall not exceed 10 μ g / g. The test of ethylene oxide residue can be performed with Labthink GC-7800 Gas Chromatograph.
