Abstract
Description
Technical Field
[0001] This invention relates to the field of hygiene products technology, specifically to diapers that combine limb restraint and breathability. Background Technology
[0002] Disposable diapers are primarily for infants. With current products, once the diaper is soaked with urine, it completely loses its breathability. This lack of breathability, combined with the diaper becoming thicker after absorbing urine, creates continuous pressure on the infant's perineum, causing local discomfort. Simultaneously, urine and feces can easily irritate the skin, leading to diaper dermatitis (also known as neonatal diaper dermatitis). This is a common skin condition in newborns, clinically manifesting as redness of the skin around the anus, buttocks, and perineum, accompanied by scattered papules or vesicles.
[0003] Currently, disposable diapers are usually fitted to the perineum of newborns to efficiently absorb urine. However, this can also lead to poor local ventilation, increasing the risk of diaper rash and bedsores. Since caregivers cannot stay with newborns at all times, and newborns cannot express their needs or discomfort verbally, caregivers often find it difficult to notice and change diapers in time. In addition, if newborns experience skin discomfort due to urine or feces while sleeping, they may unconsciously scratch the diaper, causing it to loosen. Summary of the Invention
[0004] To address the problems in the prior art, this invention provides a diaper that combines limb restraint and breathability.
[0005] The technical solution adopted by the present invention to solve its technical problem is: a diaper with both limb restraint and breathability functions, including a diaper body, wherein both sides of the diaper body are fixedly connected with a band and a first tie; The inner side of the diaper body has a groove in the middle and a fixing frame is fixedly connected to the inner wall of the groove. A disposable flexible sensor is embedded in the inner wall of the fixing frame. The inner side of the diaper body has two sides that are symmetrically fixed to the fixing frame. Multiple second ventilation holes are opened at equal intervals at the connection between the side and the diaper body. Both sides of the diaper body are connected to a restraint mechanism, which includes a fixing sleeve and a male buckle. Two mounting pieces are symmetrically fixedly connected to the outer circumference of the fixing sleeve. A fixing rod is fixedly connected between the two mounting pieces. A female buckle is snapped onto the male buckle. A second strap is fixedly connected to the female buckle. A second fleece and a second hook-and-loop strap are fixedly connected to the second strap.
[0006] Specifically, both sides are arc-shaped and match the shape of the diaper body.
[0007] Specifically, the male buckle is fixedly connected to the main body of the diaper, and the male buckle and the corresponding first strap fixing end are on the same side.
[0008] Specifically, the fixing sleeve has a tubular structure and is made of rubber material.
[0009] Specifically, the inner side of the fixing sleeve is fixedly connected with multiple elastic rings at equal intervals, and multiple first vent holes are opened at equal intervals on the elastic rings.
[0010] Specifically, the thickness of the second strap is the same as the distance between the two corresponding mounting pieces, and the movable end of the second strap passes between the corresponding fixing rod and the fixing sleeve.
[0011] Specifically, the movable end of the first strap passes through the corresponding loop, and a first fleece tape and a first hook-and-loop tape are fixedly connected to the first strap, with the area of the first fleece tape being larger than the area of the first hook-and-loop tape.
[0012] The beneficial effects of this invention are: (1) The present invention forms a dome-like structure by setting a fixed frame on the inner side of the diaper body, and with the side design with second ventilation holes on both sides, it can not only ensure the sealing, but also avoid the newborn's perineum from being too close. While eliminating local pressure, it ensures that the urine absorption function is not affected.
[0013] (2) The present invention is equipped with a disposable flexible sensor inside the fixed frame, which can detect the odor of feces in real time. When the newborn defecates, the sensor can automatically send a reminder to the caregiver so that the diaper can be changed in time, thereby effectively preventing diaper rash.
[0014] (3) By setting two restraint mechanisms on the diaper, the present invention can form a stable restraint on the newborn's upper limbs, prevent the newborn from unconsciously scratching the diaper during sleep, thus avoiding the occurrence of side leakage. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0019] like Figures 1-4 As shown, the present invention provides the following technical solution: Example 1: A diaper that combines limb restraint and breathability. Both sides of the diaper body 1 are fixedly connected with a ring band 2 and a first strap 3. The movable end of the first strap 3 passes through the corresponding ring band 2. A first fleece band 4 and a first hook-and-loop band 5 are fixedly connected to the first strap 3. The area of the first fleece band 4 is larger than the area of the first hook-and-loop band 5.
[0020] When using, place the diaper body 1 under the newborn's crotch, covering the newborn's perineum. Pass the movable end of the first strap 3 through the loop 2, then fold the first strap 3 back and attach the first hook face 5 to the first fleece 4. If you need to adjust the tightness, you can continue to pull the movable end of the first strap 3 to adjust the position of the first hook face 5 on the first fleece 4 and fix the diaper body 1 in place.
[0021] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a groove is provided in the middle of the inner side of the diaper body 1, and a fixing frame 7 is fixedly connected to the inner wall of the groove. A disposable flexible sensor 8 is embedded in the inner wall of the fixing frame 7. Two side edges 9 are symmetrically fixedly connected to the inner side of the diaper body 1 about the fixing frame 7. Both side edges 9 are arc-shaped and match the shape of the diaper body 1. Multiple second ventilation holes 10 are provided at equal intervals at the connection between the side edges 9 and the diaper body 1.
[0022] When putting on the diaper, insert it under the newborn's crotch, ensuring that the fixing frame 7 covers the outside of the newborn's perineum, while the side edge 9 is against the newborn's skin. When the newborn urinates, the urine is absorbed by the inner part of the diaper body 1 inside the fixing frame 7. This inner part of the diaper body 1 is concave, similar to a dome structure. Even if the diaper body 1 becomes thick after absorbing urine, the newborn's perineum will not be under pressure. This design also facilitates air circulation, and the air inside and outside the diaper body 1 will flow through the second ventilation hole 10, ensuring that the diaper body 1... Even when wet with urine, it remains breathable, keeping the covered skin surface dry and increasing the comfort of the diaper body 1. When the newborn defecates, the disposable flexible sensor 8 (existing technology) detects the odor of the feces. When it comes into contact with the gas of the feces, the conductivity of the material of the disposable flexible sensor 8 changes, and this change is converted into an electrical signal and amplified. When the signal reaches a preset threshold, the disposable flexible sensor 8 sends a prompt message to the caregiver's smart device via Bluetooth, prompting the caregiver to change the diaper body 1 of the newborn in time.
[0023] Example 3: The technical solution of this example, which differs from that of Example 2, includes: a restraint mechanism 6 connected to both sides of the diaper body 1. The restraint mechanism 6 includes a fixing sleeve 61 and a male buckle 62. The fixing sleeve 61 is tubular and made of rubber. Multiple elastic rings 63 are fixedly connected at equal intervals on the inner side of the fixing sleeve 61. Multiple first ventilation holes 64 are opened at equal intervals on the elastic rings 63. Two mounting pieces 65 are symmetrically fixedly connected to the outer circumference of the fixing sleeve 61. A fixing rod 66 is fixedly connected between the two mounting pieces 65. The male buckle 62 is fixedly connected to the diaper body 1, and the male buckle 62 and the corresponding first strap 3 are on the same side. A female buckle 67 is snapped onto the male buckle 62. A second strap 68 is fixedly connected to the female buckle 67. The thickness of the second strap 68 is the same as the distance between the corresponding two mounting pieces 65. The movable end of the second strap 68 passes between the corresponding fixing rod 66 and the fixing sleeve 61. A second fleece 69 and a second hook face 610 are fixedly connected to the second strap 68.
[0024] After putting on the diaper body 1, put the retaining sleeve 61 on the newborn's wrist. Under the elasticity of the retaining sleeve 61, it will be fixed on the newborn's wrist. At this time, the elastic ring 63 will support the retaining sleeve 61, and the air inside and outside the retaining sleeve 61 will flow through the first ventilation hole 64 to prevent the wrist from sweating and causing the newborn to sweat. Then, pass the movable end of the second strap 68 between the retaining rod 66 and the retaining sleeve 61, fold it back and continue to pull the second strap 68. Just make sure that the newborn's hands cannot easily grab the first strap 3 when swinging. Then, stick the second hook face 610 to the second fleece 69 to restrain the newborn's hands. When changing the diaper body 1 later, you can grab the second strap 68, pull the female buckle 67 off the male buckle 62 and snap it onto the male buckle 62 of the new diaper body 1.
