Definitions

  • the present invention relates to a breathable disposable hygiene product and a gas circulation device comprising the same.
  • Hygiene products such as diapers and sanitary napkins have been used for a long time by various users of all ages.
  • fabric diapers such as cotton and small intestines have been used from the long past, and suitable materials and functions have been subdivided to solve the limitations of cotton fabrics and developed into present complex hygiene products.
  • Disposable hygiene products represented by diapers and sanitary napkins have contributed to improving the quality of life of users.
  • the adult diaper market is growing, and adult diapers have become a major product that supports the lives of the elderly and patients.
  • Disposable sanitary products currently on the market may provide quick wearing and convenience of post-processing. Accordingly, the usage of disposable hygiene products has gradually increased.
  • the main materials used for disposable hygiene products include non-woven fabrics, super absorbent polymers, and moisture-permeable films.
  • the non-woven fabric is mainly used as a surface material in direct contact with the skin.
  • the wet-laid nonwoven fabric including rayon and pulp has a problem in that strength decreases when wet.
  • a dry nonwoven fabric including an adhesive may cause a decrease in flexibility due to an adhesive component.
  • spunbond, spunlace, and thermalbond nonwoven fabrics using polyolefin-based materials are mainly used as nonwoven materials, and the weight and strength have been increased.
  • Super Absorbent Polymer (SAP) is a material for absorbing defecation and menstrual blood, and polyacrylate-based polymers with very high absorption and retention capacity compared to conventional absorbent paper or cotton pulp are mainly used.
  • Korean Patent Registration No. 10-2079316 discloses a disposable diaper for accommodating excreted urine and feces, but does not provide a solution for reducing moisture in the diaper wearing area.
  • An object of the present invention is to provide a breathable disposable hygiene product capable of removing moisture from a wearing part of the hygiene product, and a gas circulation device including the same.
  • Breathable disposable hygiene products include a surface layer, an absorbent layer disposed under the surface layer, a ventilation layer disposed under the absorbent layer and including a ventilation hole and a hose insertion hole, and a waterproof layer disposed under the ventilation layer Including, an empty space is provided between the absorbent layer and the waterproof layer by the ventilation layer, and the ventilation hole and the hose insertion hole may communicate with the empty space independently of each other and the outside of the breathable disposable hygiene product.
  • the absorption layer is a liquid dispersion layer that quickly absorbs and disperses a liquid such as urine flowing through the surface layer from the surface layer, and a liquid storage that absorbs and stores the liquid flowing in from the liquid dispersion layer so as not to be released again layers may be included.
  • a film layer may be disposed below the absorption layer.
  • the ventilation layer may include a bonding portion for bonding the film layer and the outer peripheral surface of the waterproof layer.
  • it may further include a fabric layer on any one or more of the lower film layer and the upper waterproof layer.
  • an embossing pattern may be formed on at least one of the lower surface of the film layer and the upper surface of the waterproofing layer.
  • the ventilation layer may further include a barrier rib for controlling an air flow path.
  • the ventilation layer may further include a side outlet through which air is discharged to the side.
  • a plurality of the ventilation holes may be formed, and each may be arranged to communicate with the surface layer or the absorption layer.
  • the vent may be arranged at the edge of the hygiene product.
  • a gas circulation device includes the breathable disposable hygiene product, an air pump including an air supply port and an air intake port, a first hose connected to the breathable disposable hygiene product from the air supply port, and the air intake port a second hose connected to the breathable disposable hygiene product, and a plurality of valves.
  • the air pump may be a diaphragm pump or a fan blade pump.
  • a plurality of air pumps each comprising an air inlet and an air inlet, the air pumps respectively connected to the breathable disposable hygiene product through a plurality of hoses, the air pumps each having a gas flow rate and a control device for adjusting the supply time.
  • a filter attached to the first hose or the second hose may be further included.
  • the filter may include an aggregator for controlling the flow of air supplied from the air pump.
  • the filter may include an air purifier.
  • Breathable disposable hygiene products include a surface layer, an absorbent layer, a breathable layer and a waterproof layer, an empty space is provided between the absorbent layer and the waterproof layer by the ventilation layer, and the empty space and The outside of the breathable disposable hygiene product may be in communication.
  • the breathable disposable hygiene product can prevent skin troubles such as eczema, diaper rash, skin sores, and bedsores by controlling moisture in the worn area and causing gas circulation.
  • the ventilation layer may further include a side outlet through which the air is discharged to the side and a partition wall for controlling the flow path of the air.
  • a gas circulation device may include an air pump, a hose, a filter, a safety connector, and a breathable disposable hygiene product, and the air pump may include an air supply port and an air intake port.
  • the pumping and conveying of the fluid can be generated through the supply and suction of air. Therefore, the circulation of the gas can be easily controlled, and the gas can be supplied even with a low voltage and low capacity power source.
