What are the service life and storage conditions of medical nitrile examination gloves?

Medical nitrile examination gloves have become important protective equipment in the medical industry due to their superior performance and wide applicability. Understanding their service life and storage conditions is the key to ensuring their effectiveness and safety. The following will introduce these two aspects in detail.

1. Service life
Definition of service life
The service life of medical nitrile examination gloves generally refers to the validity period of the gloves under normal use. This period of time is related to a variety of factors, including the material quality of the gloves, the use environment, and the frequency of use.

Influencing factors

Material properties: High-quality nitrile gloves usually have a long service life. Choosing gloves that meet international standards, such as FDA or ASTM certified products, can improve the durability of gloves.
Use environment: The life of gloves may be affected when they are used in contact with chemicals, grease, or high temperature environments. Frequent contact with these substances will cause the glove material to deteriorate and shorten the use time.
Frequency of use: The more frequently the gloves are used, the faster they will wear and age. Therefore, medical staff should change their gloves regularly in high-intensity use scenarios.
Replacement recommendations
It is generally recommended to change gloves after each operation, especially when handling different patients or potentially infected materials. In addition, if the gloves are damaged, leaking, or have obvious signs of aging (such as discoloration, embrittlement), they should be replaced immediately.

2. Storage conditions
Temperature and humidity
Medical nitrile examination gloves should be stored in a dry, cool place, away from direct sunlight. The ideal storage temperature is room temperature (about 20-25°C), and the relative humidity should be maintained between 40%-60%. Excessive temperature and humidity will accelerate the aging process of gloves.

Avoid contact with chemicals
When storing gloves, avoid contact with chemicals, greases and other substances that may cause material degradation. These chemicals may have a corrosive effect on the glove material and reduce its performance.

Packaging integrity
When storing, the original packaging of the gloves should be kept intact and avoid exposure to the external environment. Packaging can effectively prevent the gloves from moisture and contamination, extending their service life.

Regular inspection
Check the stored gloves regularly to ensure that they are not damaged, deformed or expired. Expired gloves should not be used again and should be properly disposed of.
