Description

Technical Field

[0001] This utility model relates to the field of infant care technology, and more specifically, to a bird's nest device for newborns. Background Technology

[0002] Clinically, newborns, especially premature infants, require special care because their organ functions and immune functions are not yet fully developed. Currently, medical staff often use a structure that simulates a bird's nest to restrict the position of infants and young children, making them feel comfortable and safer.

[0003] For example, Chinese patent CN205181682U discloses a newborn nest, the structure of which includes a nest body consisting of a base, a U-shaped groove, and a cover. The base is semi-circular and consists of a pure cotton fabric layer filled with cotton or washed cotton, a diaper pad, and a sponge layer, placed inside the opening of the U-shaped groove. The front two sides of the U-shaped groove have gently sloping protrusions for attaching visual acuity development cards, and the inner side is covered with a flesh-colored non-pilling fleece layer. The lower arc-shaped part has a zipper or hook and loop fastener. The cover is made of double-layered pink fabric and is fixed to the U-shaped groove by fastening straps and hook and loop fasteners. The upper part has a ventilation window with a flip-top. Its U-shape mimics the uterine environment, which can maintain the newborn's physiological position, reduce energy consumption, increase milk intake, and maintain body temperature. However, the combination of the newborn nest base and the U-shaped groove creates a fixed space. For smaller infants, this may lead to a lack of security due to insufficient swaddling. For larger infants, the limited space may restrict their movement. Furthermore, if traditional Chinese medicine is to be applied to the newborn, the medicine bag needs to be secured separately. This requires the use of straps or Velcro, which may put additional pressure on the newborn's torso or limbs. This contradicts the original design of the nest, which simulates the "unrestricted swaddling feeling" of the womb. In particular, it may affect the natural extension of the limbs of premature infants.

[0004] In view of this, it is indeed necessary to provide a technical solution to the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a bird's nest device for newborns, addressing the above-mentioned deficiencies of the prior art.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A bird's nest device for newborns is constructed, comprising a semi-closed ring-shaped flexible outer shell, inside which a replaceable inner liner is nested.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] A bird's nest device for newborns, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes a semi-closed ring-shaped flexible outer jacket 1, inside which is a replaceable inner liner 2. Adjustable components 3 are located on both sides of the open end of the inner liner 2. These components adjust the diameter of the inner liner 2 by changing the connection position of the two sides of the open end. It also includes an external application component 4 for carrying topical medication. The two ends of the external application component 4 are detachably connected to opposite sides of the inner liner 2 to ensure the medication adheres to the newborn's skin. Specifically, both the flexible outer jacket 1 and the inner liner 2 are made of flexible material. The flexible outer jacket 1 is fitted onto the inner liner 2, forming a semi-closed ring structure. This allows for flexible deformation depending on the placement scenario, and the semi-closed design simulates the uterine environment, providing a sense of security for the newborn. The adjustable components 3 on both sides of the open end of the inner liner 2 adjust the diameter of the inner liner 2 by changing their connection position. For example, when the connection point moves inward, the diameter of the inner liner 2 decreases, enhancing its wrapping effect for smaller newborns; when the connection point moves outward, the diameter increases, accommodating the movement needs of larger newborns. The two ends of the external application component 4 are detachably connected to the opposite sides of the inner liner 2. By adjusting the connection position, the external application drug layer is kept in close contact with the newborn's skin, ensuring that the drug can effectively act on the skin surface, while also facilitating disassembly and replacement according to care needs.

[0029] This application addresses the problem of insufficient swaddling or space restriction for newborns of different sizes using traditional fixed-size nest-like devices by adjusting the diameter of the inner liner 2 using the adjustable component 3, thus improving their sense of security and freedom of movement. The semi-enclosed, flexible ring structure combined with the soft touch of pure cotton effectively simulates the compactness and comfort of the womb, reducing the startle reflex and promoting sleep in newborns. The external application component 4 is detachably connected to the inner liner 2, integrating medication application and positional support functions, avoiding the displacement or decreased comfort issues caused by the separate fixation of the herbal bag in traditional methods, and simplifying nursing procedures. The inner liner 2 can be removed and replaced from the flexible outer cover 1 for easy cleaning and disinfection, preventing medication or secretions from seeping into the interior, reducing the risk of cross-infection, and meeting the needs of efficient clinical nursing. The flexible outer cover 1 is made of pure cotton, which has good breathability and skin-friendliness, reducing the risk of skin allergies in newborns, while its soft material is unlikely to cause friction damage.

[0030] Furthermore, the semi-closed ring-shaped openable structure of the flexible outer jacket 1 specifically means that the flexible outer jacket 1 has an opening that communicates with the interior, and detachable connecting components are provided on both sides of the opening. The detachable connecting components can be Velcro, snaps, or zippers. By opening the connecting components, the opening of the outer jacket is enlarged, and the inner liner 2 can be inserted or removed from the opening. After closing the connecting components, the outer jacket returns to its semi-closed ring-shaped structure and wraps the inner liner 2.

[0031] This invention is used in conjunction with a neonatal mattress. The bird's nest device is placed on the mattress, and the inner liner 2 of the bird's nest is adjusted to a suitable enclosing diameter. The newborn is then placed inside the bird's nest device. In some embodiments, a nursing pad can be detachably connected to the bottom of the flexible outer cover 1 to further improve the newborn's comfort.

[0032] In some embodiments of this application, such as Figure 4As shown, the external application component 4 includes an isolation layer 41, a drug-carrying layer 42 below the isolation layer 41, forming a cavity 421 for containing the externally applied drug, and a breathable layer 43 below the drug-carrying layer 42 for contact with the newborn's skin. The edges of the isolation layer 41 extend to form a sealing edging, wrapping the edges of the drug-carrying layer 42 and the breathable layer 43. Fixed side wings 44 connected to the inner liner 2 are provided on opposite sides of the isolation layer 41. Specifically, the isolation layer 41 is located on the outermost layer, preventing the externally applied drug from contacting the inner liner 2 and preventing leakage of the drug solution into the device. The drug-carrying layer 42 is below the isolation layer 41, forming a cavity 421 for containing the drug, and its openable / closable design allows for drug insertion and closure. The breathable layer 43 is close to the newborn's skin, allowing for effective drug penetration while ensuring skin comfort and breathability. The edge of the isolation layer 41 extends to form a sealed edge, wrapping the edges of the drug-carrying layer 42 and the breathable layer 43 to prevent the drug from overflowing or falling from the side; the fixed side wings 44 on both sides of the isolation layer 41 are detachably connected to the inner liner 2 to ensure that the external application component 4 is stably attached to the surface of the newborn's skin and to prevent displacement.

[0033] It should be noted that the material of the isolation layer 41 can be a waterproof membrane of thermoplastic polyurethane, PVC waterproof coated fabric, polyethylene composite film or waterproof non-woven fabric, the material of the drug carrier layer 42 can be medical grade non-woven fabric or breathable cotton gauze, and the material of the breathable layer 43 can be medical degreased cotton gauze or breathable non-woven fabric.

[0034] Furthermore, the detachable connection structure between the fixed side wing 44 and the inner liner 2 can be configured as a Velcro structure, a button structure, or a slot structure. In a button structure, a male snap is provided at the end of the fixed side wing 44, and a female snap is provided at the corresponding position on the inner liner 5; fixation is achieved by inserting the male snap into the female snap. In a slot structure, a strip-shaped slot is provided on the surface of the inner liner 2, and the end of the fixed side wing 44 is designed as a protrusion that can be inserted into the slot; fixation is achieved by the engagement of the protrusion with the slot.

[0035] In some embodiments of this application, the cavity 421 of the drug carrier layer 42 has an openable opening for sealing the cavity 421 after the drug is placed therein. Specifically, when an externally applied drug needs to be placed, the openable opening of the cavity 421 of the drug carrier layer 42 is opened to place the externally applied drug into the cavity 421; after placing the drug, the opening of the cavity 421 is closed, forming a closed space and thus fixing the drug within the cavity 421. The openable opening allows for easy opening of the cavity 421 when the externally applied drug needs to be replaced or added, making the operation simple and quick; after the opening is closed, the cavity 421 is in a closed state, effectively preventing the drug from scattering or falling out of the cavity 421, keeping the drug in a predetermined position, ensuring that the drug adheres to the newborn's skin to exert its effect.

[0036] In some embodiments of this application, multiple guide rings 45 are spaced apart along the height direction on both sides of the inner liner 2, through which the fixing wings 44 pass. The fixing wings 44 adjust the tightness of contact between the breathable layer 43 and the newborn by passing through the guide rings 45 at different heights. Specifically, the guide rings 45 are made of non-woven fabric and are sewn to the flexible outer jacket 1 at both ends to form guide rings 45 through which the fixing wings 44 pass. Multiple guide rings 45 are spaced apart along the height direction on both sides of the inner liner 2, and the fixing wings 44 of the outer dressing component 4 can pass through these guide rings 45. By passing the fixing wings 44 through the guide rings 45 at different heights, the position of the outer dressing component 4 in the vertical direction is changed, thereby adjusting the relative tightness between the breathable layer 43 and the newborn's skin. The fit between the breathable layer 43 and the skin can be flexibly adjusted according to the newborn's body shape or care needs, avoiding excessive tightness that compresses the skin or excessive looseness that causes drug displacement. It adapts to the body curves of different newborns, ensuring that the external medication adheres evenly to the skin, while reducing discomfort or the risk of skin damage caused by excessive tightness.

[0037] In some embodiments of this application, the inner liner 2 includes a waterproof wrapping layer 21. The waterproof wrapping layer 21 forms an openable and closable cavity, within which a filling layer 22 is placed. The filling layer 22 encapsulates traditional Chinese medicine granules. Specifically, the waterproof wrapping layer 21 forms a closed space. The internal cavity is designed with an opening and closing structure to allow the filling layer 22 to be inserted and removed. The traditional Chinese medicine granules encapsulated in the filling layer 22 include, but are not limited to, cassia seeds. These granules are fixed inside the inner liner 2 by the closed state of the cavity. The cassia seed granules come into contact with the newborn through the filling layer 22 or release pharmacological components. Utilizing their properties of calming the mind and promoting sleep, regulating dampness, and clearing the liver and improving eyesight, they act on the newborn's body, providing auxiliary care for calming the mind and promoting sleep, regulating internal dampness, and improving eye health, thus enhancing the functionality of the bird's nest device. The waterproof wrapping layer 21 prevents medicinal liquids or secretions from penetrating into the filling layer 22, avoiding moisture damage and inactivation of the traditional Chinese medicine granules. The openable and closable cavity facilitates regular replacement of the filling layer 22, maintaining the continuous efficacy of the medicine.

[0038] It should be noted that the flexible outer jacket 1 is made of pure cotton, and the waterproof wrapping layer 21 of the inner liner 2 can be made of thermoplastic polyurethane with excellent waterproof and moisture-proof properties; the filling layer 22 can be made of medical degreased cotton, memory foam, polyester fiber filling cotton or breathable sponge; Chinese medicine granules can be sealed inside the filling layer 22 through non-woven fabric or gauze.

[0039] Furthermore, the inner liner 2 has an openable and closable cavity structure, specifically, a detachable connecting component is provided on one edge of the waterproof wrapping layer 21. The connecting component can be Velcro, snaps, or zippers, thereby forming an openable and closable cavity opening. After opening the connecting component, the cavity opening expands, allowing the filling layer 22 to be inserted or removed from the opening; after closing the connecting component, the cavity is closed, fixing the position of the filling layer 22.

[0040] In some embodiments of this application, such as Figure 5 As shown, the adjustment component 3 includes an adjustment band 31 fixed to one edge of the opening end of the inner liner 2. The adjustment band 31 is provided with an adjustment position, and multiple connection points are provided at intervals on the other edge of the opening end of the inner liner 2. By connecting the adjustment position to the connection points at different positions, the inner liner 2 can be tightened or loosened, thereby adjusting the circumferential diameter of the inner liner 2.

[0041] Specifically, the adjustment strap 31 is fixed to one edge of the opening of the inner liner 2, and has an adjustment position on it; multiple connection points are distributed at intervals on the other edge. By connecting the adjustment position to the connection points at different positions, the relative distance between the two edges of the opening is changed; when the connection point connected to the adjustment position is moved inward, the opening of the inner liner 2 contracts, and the circumferential diameter decreases; when the connection point connected to the adjustment position is moved outward, the opening of the inner liner 2 expands, and the circumferential diameter increases. For smaller newborns, the diameter of the inner liner 2 is reduced to enhance the feeling of being wrapped, simulating the uterine environment and improving their sense of security; for larger newborns, the diameter is increased to avoid space restriction and ensure freedom of movement. By adjusting the connection position, the tightness or looseness of the inner liner 2 can be precisely controlled, avoiding excessive tightness that compresses the newborn's body or excessive looseness that causes the wrapping to fail, thus improving nursing comfort. No complicated tools are required; diameter adjustment can be achieved by quickly connecting and disconnecting the adjustment position and the connection points, meeting the efficient operation requirements of clinical nursing.

[0042] Furthermore, the number of adjustment positions can be set to 1, 2, 3, 4, 5 or 6 as needed; the number of connection points can be set to 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 or 16 as needed; and the number of adjustment positions is lower than the number of connection points.

[0043] In some embodiments of this application, the adjustment position is a male button seat 32, and the connection point is a female button seat 33. Specifically, the male button seat 32 is fixed to one end of the adjustment band 31 as the adjustment position, and the female button seats 33 are spaced apart on the other side edge of the opening end of the inner liner 2 as connection points. By inserting the male button seat 32 into the corresponding female button seat 33, the adjustment band 31 is fixed to the edge of the inner liner 2; when the connection position of the female button seat 33 is changed, the tension of the adjustment band 31 can be changed, thereby adjusting the circumferential diameter of the inner liner 2.

[0044] In some embodiments of this application, such as Figure 6As shown, it also includes a fixing component 5, whose two ends are detachably connected to opposite sides of the inner liner 2 and are located above the inner liner 2, for limiting and fixing the newborn inside the inner liner 2. Specifically, the fixing component 5 is detachably connected to opposite sides of the inner liner 2 and is located above the inner liner 2. By connecting the fixing component 5 to both sides of the inner liner 2, a lateral constraint is formed above the newborn, thereby limiting the newborn's range of motion inside the inner liner 2 and achieving limiting and fixing. Through the constraint effect of the fixing component 5 above the inner liner 2, the newborn's body is prevented from shifting inside the inner liner 2 due to movement, maintaining a comfortable position; the limiting effect of the fixing component 5, combined with the wrapping structure of the inner liner 2, further simulates the compact environment inside the womb, enhancing the newborn's sense of security and reducing anxiety.

[0045] In some embodiments of this application, the fixing component 5 includes a first fixing strap 51 and a second fixing strap 52 respectively connected to both sides of the inner liner 2. The ends of the first fixing strap 51 and the second fixing strap 52 are connected and disconnected by a connector. Specifically, the first fixing strap 51 and the second fixing strap 52 are respectively connected to opposite sides of the inner liner 2, and their ends are detachably closed by a connector. By wrapping the first fixing strap 51 and the second fixing strap 52 around the newborn above the inner side of the inner liner 2 and closing both ends by the connector, a lateral restraint strap is formed, thereby restricting the newborn's range of motion and achieving fixed positioning. The detachable connection method facilitates quick assembly and disassembly during care, such as changing diapers or checking the newborn, without affecting the efficiency of daily care operations.

[0046] It should be noted that the fixed side wing 44, the first fixed strap 51, the second fixed strap 52 and the adjusting strap 31 are all connected to the inner liner 2 and pass through the flexible outer sleeve 1 during use.

[0047] In some embodiments of this application, the connector includes a hook-and-loop fastener 531 on the first fixing strap 51 and a loop fastener 532 on the second fixing strap 52. The hook-and-loop fastener 531 and the loop fastener 532 cooperate to form a detachable connection. Specifically, the hook-and-loop fastener 531 is provided at the end of the first fixing strap 51, and the loop fastener 532 is provided at the end of the second fixing strap 52. The detachable connection is achieved through the physical hook-and-loop connection. When the hook-and-loop fastener 531 is pressed onto the loop fastener 532, the hooks embed into the loop structure to form a fixation. When torn in the opposite direction, the hooks separate from the loops, thus breaking the connector. The re-adhesive nature of the Velcro allows caregivers to adjust the tension of the fixing straps at any time according to the newborn's body shape, avoiding excessive tightness causing compression or excessive looseness causing displacement. No additional tools are required; connection and disconnection can be completed by pressing or tearing, meeting the needs of rapid operations in clinical care, such as changing diapers and removing newborns.

[0048] The flexible outer jacket 1, inner liner 2, adjustment component 3, outer covering component 4, and fixing component 5 of this utility model are all detachable structures, and components with corresponding functions can be selected according to needs, making it highly flexible in use.

[0049] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
