If there is a blood clot, it does not affect the use of tampons. In addition to normal menstrual blood, there are usually clots or endometrial shedding and other phenomena during the physiological stage. Moreover, the tampon itself will only absorb the liquid-like menstrual blood, and the mucous membrane of the clot that is discharged in a slightly solid state will stick to the tampon slightly. They will drag out when you change out. This is the same as using tampons, these will adhere to the surface of the tampon and will not be penetrated.

Diaper testing is generally based on the standard GB / T 28004- -2011 Diapers (pieces, mat), which stipulates important quality indicators such as permeability, pH value and delivery moisture, among which permeability includes three indicators of slip seepage, reinfiltration and leakage, as well as basic indicators such as size and quality deviation.In addition, the standard GB / T 28004-2011 Diapers (sheets, pads) also stipulates that the sanitary indicators of diapers shall be implemented in accordance with GB 15979-2002 Sanitary Standards for Disposable Sanitary Products, and the fluff pulp used in diapers shall comply with GB / T 21331 and high absorbent resin shall comply with GB / T 22905 Diapers High Absorbent Resin.

The test results of diapers by the comprehensive baby diaper inspection agency show that there are three problems with the quality of diapers in general: hygiene indicators, permeability and pH value. Children and incontinent adults are diaper users, and the resistance of this group is weak, and the failure of hygiene indicators will affect the health of users. Hygiene indicators of raw materials, environmental hygiene control of production and processing, storage and transportation conditions may lead to the failure of hygiene indicators of baby diapers. Permeability is measured by three indicators: slip permeability, back permeability and leakage. Diapers with poor permeability cannot absorb and fix liquid well, which easily leads to users feeling wet and uncomfortable and affects skin health. Permeability is generally related to the characteristics of the raw materials used in the product, such as the surface layer, infusion layer and absorption layer of baby diapers. The pH value of baby diapers reflects the acidity or alkalinity of the product. Exceeding the pH value may lead to skin irritation or red rash. The pH value of diapers is affected by raw materials, storage and transportation environment and other factors.

The following characteristics can be considered as purchase indicators. (1) Material: Effective diapers have a light texture and soft edges that do not irritate or scratch. (2) Absorbency: The pad draws urine into it and keeps it dry when it comes in contact with the skin. (3)Three-dimensional protective enclosure: Current diapers are equipped with three-dimensional protective enclosure to ensure no side leakage. When choosing diapers, pay attention to whether the rubber band used in the three-dimensional circumference is fine and elastic enough, otherwise it will strangle the baby's skin and may cause side leakage of urine. (4) Elastic waistband: In addition to the material, fit is also an important consideration. Parents must choose the right size according to the size of baby's butt. Increasing the elastic waistband will keep the diaper close to the baby and avoid back leakage. (5) Tape: sticky and best to be pasted repeatedly; in addition, the tearing sound should not be too loud so as not to wake up the sleeping baby; not too hard, otherwise it will easily scratch the baby.
