Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially relates to a premature bird nest for prone position ventilation and turning over. BACKGROUND

[0002] Many domestic and foreign studies have shown that prone position can reduce apnea, hypoxemia, bradycardia, reduce gastroesophageal reflux, increase gastrointestinal tolerance, reduce heat consumption, reduce withdrawal reaction, enhance approach reaction, prolong sleep and relieve stress in premature infants. The current clinical method for turning over premature infants in prone position is the 1 / 4 gradual body position turning over method. The operator holds the premature infant with both hands to calm the infant until the infant adapts to the body position, and then turns over another 1 / 4, and so on until the infant completes the turning over in prone position. Although this method can gradually change the body position of premature infants, it also has some obvious defects. First, the operation time is long and labor-intensive, which not only increases the workload of nursing staff, but also may cause unnecessary stress to premature infants due to frequent changes in body position. Second, during the turning over process, the operator needs to turn over with both hands, which cannot provide continuous holding and calming for the premature infant, which may cause the premature infant to experience greater physical and mental stimulation during the turning over process, affecting the stability of their physiology and psychology.

[0003] In addition, the existing turning over incubators or devices for newborns or premature infants on the market are mainly limited to assisting the conversion between supine position, left lateral position and right lateral position, and cannot effectively assist in completing the prone position ventilation of the infant. The existing prone position ventilation pillows or pads usually need to be used after the infant completes the turning over in prone position, and are mainly used to maintain prone position ventilation, and cannot assist in completing the turning over action, which limits their application in premature infant care.

[0004] The patent document with publication number CN214180917U discloses a composite infant positioning tool, which includes a base, a protective enclosure sewn on the top of the base, a head ring placed on the top of the base, a headrest and a throw pillow placed on the top of the base, two fixed belts sewn on the right edge of the base, and the inside of the base, protective enclosure, head ring, headrest and throw pillow are filled with cotton blocks covered with wipeable and sterilizable polyurethane waterproof fabric.

[0005] The spontaneous active movement of the hands and feet of premature infants not only includes left and right directions, but also includes upward direction. The slow rebound memory foam used in this patent document can provide cushioning for left and right direction movement, but it lacks assistance for upward movement, which limits its effectiveness in promoting the full range of motion recovery of premature infants. In addition, premature infants of different gestational weeks differ in size and weight, and the nest body cannot adapt to this change, resulting in its inability to provide appropriate support and comfort for premature infants of different gestational weeks.

[0006] In summary, the special tools for prone position turning over of premature infants have not been widely used at present. Medical staff generally lack awareness of turning over tools, and fail to realize that these tools can provide necessary support for premature infants during turning over process. In addition, medical staff lack understanding of the importance of spontaneous active movement of premature infants in skeletal muscle development, resulting in most of the designed bird nests for premature infants lacking flexibility and being unable to effectively help premature infants recover to the flexion neutral functional position after spontaneous movement.

[0007] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, a large number of literatures and patents have been studied by the applicant when making the utility model, but all details and contents have not been listed in detail due to the limitation of the volume, which is by no means that the utility model does not have the characteristics of the prior art, on the contrary, the utility model has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art in the background art. Content of the utility model

[0008] In view of the deficiencies of the prior art, the utility model provides a bird nest for prone position ventilation turning over of premature infants, which comprises a nest body and a sandwich pad which are detachably connected with each other, the nest body comprises a plurality of first zipper strips arranged on the upper surface and the lower surface, the zipper strips can be bent so that one of the first zipper strips can be connected with a second zipper strip arranged on the surface of the sandwich pad, thereby preliminarily defining a semi-enclosed internal cavity on the surface of the sandwich pad for accommodating the premature infant, wherein the sandwich pad comprises two layers of pads which are overlapped and closed along three edges, and one edge is open to form a bag opening structure, so that a pad plate with a shape and area matched with the pad for providing support force for turning over the premature infant can be put in or taken out through the open bag opening.

[0009] By overlapping the two layers of pads and closing along the three edges, a stable bag-shaped structure is formed. This structure not only increases the overall strength and stability of the sandwich pad, but also provides good support. When the pad plate is placed in the bag opening structure, it can evenly distribute the support force, thereby effectively supporting the premature infant during the turning over process. The zipper strips can be bent, which means that the nest body can well adapt to the curve of the body of the premature infant, reducing the discomfort during the turning over process. In addition, the detachable connection design between the nest body and the sandwich pad, and the easy operability of the zipper make the whole device very convenient to use and clean. Medical staff can quickly and easily adjust the size and shape of the bird nest, and it is also convenient for regular cleaning and disinfection of the device, ensuring the health and safety of the premature infant.

[0010] According to a preferred embodiment, the nest body comprises a free section connected at the end of the zipper section, the free section is configured with a female fastener at the end face away from the zipper section, and the inner side face of the zipper section is configured with a plurality of spaced-apart male fasteners along the length direction thereof. When the zipper section is connected with the sandwich pad to preliminarily define the internal cavity, the end face of the free section curved towards the internal cavity further defines the fully enclosed internal cavity in a manner of fitting the inner side face of the zipper section, and the female fastener selectively fastens with a certain male fastener to adjust the perimeter of the internal cavity. The design of the free section and the cooperation of the female and male fasteners make the perimeter of the internal cavity adjustable according to the needs. This flexibility is particularly suitable for premature infants or newborns of different body types (especially upper body types), and can provide personalized adaptive solutions to meet different care needs. Through the curved design of the free section, the end face thereof is fitted to the inner side face of the zipper section to form a fully enclosed internal cavity. Such a structure can effectively wrap and protect the premature infant, improving safety and comfort. In addition, the use of the female and male fastener design not only enhances the stability of the overall structure, ensuring that it will not easily deform or come loose during use, but also allows medical staff to simply and quickly adjust the size of the internal cavity without complex operation procedures, reducing the workload.

[0011] According to a preferred embodiment, the angle between the end face of the free section and the inner side face thereof is configured as an acute angle, so that when the male and female fasteners are fastened, the side wall of the internal cavity can form a smooth transition. The design of smooth transition reduces the sense of abruptness of the structure, which can reduce the friction and irritation of the nest body's irregular configuration on the skin of the premature infant, thereby improving comfort.

[0012] According to a preferred embodiment, in the case that the premature infant needs to be turned over, the nest body, to which the interlayer pad has been connected on the lower surface, is connected with another interlayer pad on the upper surface, and the second zipper strips of the upper and lower interlayer pads are connected with the two first zipper strips on the upper and lower surfaces of the zipper segment of the nest body respectively, which correspond to each other in the vertical position, so as to ensure that the area of the internal cavity defined by the nest body does not change before and after the premature infant is turned over. The interlayer pad has elasticity, allowing the spontaneous active movement of the limbs of the premature infant upwardly acting on the interlayer pad, and helping the limbs of the premature infant to restore the flexion midline position. The stable internal cavity area helps to maintain the stability of the premature infant during the turning-over process, reducing the risk of falling or rolling caused by space changes. In addition, the design also enhances the structural stability of the entire nest device through the close connection of the zippers, improving the safety of use. In addition, the premature infant can make active movements to lift the limbs (especially the arms and legs) upward from the side of the body, and the elasticity of the interlayer pad provides motion assistance for such movements of the premature infant, thereby promoting the development of the skeletal muscles of the premature infant. According to a preferred embodiment, the first zipper strips include an inner first zipper strip, a middle first zipper strip and an outer first zipper strip arranged from inside to outside and parallel to each other on the surface of the zipper segment, and the second zipper strip can be engaged with the inner first zipper strip, the middle first zipper strip or the outer first zipper strip respectively to define different internal cavity areas. By providing the inner first zipper strip, the middle first zipper strip and the outer first zipper strip, and cooperating with the second zipper strip on the interlayer pad, the size of the internal cavity can be flexibly adjusted. This design allows the size of the nest space to be accurately adjusted according to the size of the premature infant, thereby providing more fitted and comfortable support.

[0013] According to a preferred embodiment, the end of the second zipper strip of the interlayer pad is provided with a zipper head for connecting with the first zipper strip, and when the interlayer pad is to be connected with the nest body, the zipper head is located at the starting end of the second zipper strip close to the female buckle, and the terminal end of the second zipper strip close to the male buckle is provided with a zipper stop to prevent the zipper head from slipping off. The design of the zipper head located at the starting end of the second zipper strip close to the female buckle ensures the stability of the connection process. When the zipper head starts to slide from the female buckle, it can move smoothly along the second zipper strip to the terminal end, forming a close connection with the first zipper strip. This stable connection helps to maintain the firmness between the interlayer pad and the nest body, preventing accidental falling during use by the premature infant.

[0014] According to a preferred embodiment, the nest includes a plurality of fixed pillows arranged in the internal cavity, including a head pillow placed on the head of the premature infant, a body pillow placed in front of the chest of the premature infant, and side pillows placed on both sides of the body of the premature infant. The head pillow, the body pillow and the side pillows provide all-round support for the premature infant. These fixed pillows can fit the body curve of the premature infant, reducing the gap between the body and the nest, thereby improving the comfort of the premature infant.

[0015] According to a preferred embodiment, the outer side of the nest body is provided with a plurality of fixing bands, which are connected to the outer side of the nest body in a manner spanning the upper and lower interlayer pads when the nest body is connected with the interlayer pads. The fixing bands can allow the spontaneous active movement of the limbs of the premature infant in front of the body, and the cooperation of the nest body and the upper and lower interlayer pads can help the limbs of the premature infant to recover the flexion midline position in all directions.

[0016] According to a preferred embodiment, one end of the fixing band is provided with a plurality of connection structures along the length direction thereof, which are selectively detachably connected with the fixing structures reserved on the outer side of the nest body to adjust the fixing strength of the fixing band applied to the bird nest. The fixing band includes two ends, i.e., a fixed end and a free end, wherein the fixed end is fixedly connected to the outer side of the zipper segment, and the free end can be detachably connected to the outer side of the zipper segment after spanning the interlayer pad. In order to conveniently and quickly realize the detachable connection between the connection structures on the fixing band and the fixing structures on the outer side of the zipper segment, the connection structures and the fixing structures can be holes, rings, buckles or magic tapes, etc., which can be detachably matched with each other. When the nest body is connected with the interlayer pad by using the first zipper band in different positions, the size of the bird nest formed (especially the width) will change. The purpose of providing a plurality of connection structures on the fixing band is to enable medical staff to select appropriate connection structures according to the width of the bird nest, so as to fix by using the effective fixing length (i.e., the length between the selected connection structure and the fixed end) of the fixing band. Specifically, selecting the connection structure closest to the free end of the fixing band will make the effective fixing length of the fixing band longer, and thus be more suitable for the case that the interlayer pad is connected with the outer layer first zipper band of the nest body; selecting the connection structure farthest from the free end of the fixing band will make the effective fixing length of the fixing band shorter, and thus be more suitable for the case that the interlayer pad is connected with the inner layer first zipper band of the nest body.

[0017] According to a preferred embodiment, the nest body has a resilient latex inner core, and the cooperation of the nest body and the interlayer pad allows the spontaneous active movement of the premature infant in all directions and helps the limbs of the premature infant to recover the flexion midline position. The outer part of the latex inner core of the nest body is configured with a double-layer antibacterial protective sleeve in a sleeved manner, and the interlayer pad is configured with an antibacterial cloth in a detachably adhesive manner on the side in contact with the premature infant. The cooperation of the nest body and the interlayer pad can provide a comprehensive support environment for the premature infant to promote their spontaneous active movement in various directions such as up and down, left and right, which helps the premature infant to better develop muscle tone and improve coordination. In addition, by respectively configuring the nest body and the interlayer pad with a double-layer antibacterial protective sleeve and a detachably adhesive antibacterial cloth, the overall safety is significantly improved. This helps to reduce the contact opportunities of the premature infant with bacteria during sleep, and reduces the risk of infection and other health problems. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be described in detail in combination with the drawings.

[0027] The utility model relates to a premature infant bird's nest which can be used for prone position ventilation and turning over. Figure 1 As shown in the drawing, the bird's nest comprises a nest body 100, the nest body 100 can be made of natural latex material with honeycomb air-permeable hole structure, and presents a long strip structure, the design allows medical staff to bend it into approximate U-shaped structure in a plane, thereby forming a semi-enclosed internal cavity capable of accommodating premature infants. Particularly preferably, observing along the length direction of the nest body 100, the cross section can be a square with side length of 10-15 cm, and the length of the nest body 100 can be 1.2-1.5 m.

[0028] Preferably, as shown in the drawing, Figure 1 , Figure 2As shown, when the medical staff manually bends the nest body 100 to form a U-shaped internal cavity, the side of the nest body 100 as the internal cavity side wall is called the inner side 130, and the opposite side is the outer side 140. The nest body 100 is divided into two main parts along its length direction: the zipper segment 110 and the free segment 120. The zipper segment 110 and the free segment 120 have a common square cross-section in the length direction, realizing seamless connection of the two parts. In the design of the zipper segment 110, the upper surface and the lower surface are respectively configured with a plurality of first zipper strips arranged along the length direction of the nest body 100. The first zipper strips are arranged in parallel and with a certain interval. Specifically, the first zipper strip adjacent to the inner side 130 is called the inner layer first zipper strip 111, the first zipper strip adjacent to the outer side 140 is called the outer layer first zipper strip 113, and the first zipper strip between them is called the middle layer first zipper strip 112.

[0029] Preferably, in combination Figures 1-3 The bird nest design of the utility model includes a sandwich pad 200 that can be detachably connected with the nest body 100. The sandwich pad 200 can be designed as two pieces, respectively configured on the upper surface and the lower surface of the nest body 100. In the preferred design, as shown, Figure 1 The upper surface of the sandwich pad 200 connected with the lower surface of the nest body 100 is provided with a U-shaped second zipper strip 210; at the same time, as shown, Figure 2 The lower surface of the sandwich pad 200 connected with the upper surface of the nest body 100 is also provided with a U-shaped second zipper strip 210 corresponding in shape and position. This design allows the sandwich pad 200 to be firmly connected with the nest body 100. The medical staff can bend the zipper segment 110 of the nest body 100 to make one of the inner layer first zipper strip 111, the middle layer first zipper strip 112 and the outer layer first zipper strip 113 match the shape and position of the U-shaped second zipper strip 210 configured on the sandwich pad 200, so that the first zipper strip and the second zipper strip 210 can be precisely engaged. This engagement ensures that the nest body 100 can be stably installed on the sandwich pad 200 when it is bent to form a U-shaped structure. This design not only provides structural stability, but also enhances the applicability and operational convenience of the bird nest in the medical environment. In the whole system, the structural design and functional positioning of the sandwich pad 200 and the zipper strip make the nest body 100 efficient and reliable during installation and disassembly. In addition, the sandwich pad 200 is soft and comfortable, and has elasticity, which can allow premature infants to move under the elastic resistance, promoting the normal development of the skeletal muscle system.

[0030] Preferably, medical personnel can selectively engage the second zipper tape 210 of the interlayer pad 200 with one of the first zipper tapes in the zipper segment 110, thereby adjusting the internal cavity area defined by the nest body 100 to accommodate the needs of preterm infants at different gestational weeks. Specifically, the shape of the second zipper tape 210 of the interlayer pad 200 is fixed. When the second zipper tape 210 engages with the inner first zipper tape 111, the inner surface 130 of the zipper segment 110 is fixed in position adjacent to the second zipper tape 210, at which point the internal cavity area of ​​the nest body 100 is maximized. Conversely, when the second zipper tape 210 engages with the outer first zipper tape 113, the outer surface 140 of the zipper segment 110 is confined in position adjacent to the second zipper tape 210, causing the inner surface 130 of the zipper segment 110 to move closer to the center of the interlayer pad 200, resulting in the minimum internal cavity area. In the preferred design, when the second zipper strap 210 engages with the outer first zipper strap 113, the internal cavity formed by the nest body 100 is suitable for preterm infants with a gestational age of 28 weeks or less. When the second zipper strap 210 engages with the middle first zipper strap 112, the internal cavity can meet the needs of preterm infants with a gestational age of 29 to 34 weeks. And when the second zipper strap 210 engages with the inner first zipper strap 111, the internal cavity defined by the nest body 100 is suitable for preterm infants with a gestational age of 34 weeks or more, as well as newborns. Through this design, the nest body 100 can provide appropriate support and protection at different stages of pregnancy to meet the physiological needs of different preterm infants.

[0031] Preferably, combined with Figure 4 and Figure 5, the zipper segment 110 of the nest body 100 can be bent into a U-shaped half-enclosure configuration for enclosing the lower half of the premature infant, which can specifically include the chest, abdomen, and legs of the premature infant, while the free segment 120 connected with the zipper segment 110 is used to seal the U-shaped half-enclosure configuration, which can enclose the upper half of the premature infant, which can specifically include the head, neck, and shoulders of the premature infant. The free segment 120 is configured with at least one female buckle 122 at an end face 121 away from the zipper segment 110, while the inner side face 130 of the zipper segment 110 is arranged with a plurality of spaced-apart male buckles 114 along the length direction thereof. After the zipper segment 110 is connected with the interlayer pad 200 and preliminarily defines the half-enclosure internal cavity, the end face 121 of the free segment 120 can be bent towards the internal cavity direction and abut against the inner side face 130 of the zipper segment 110. In this way, the free segment 120 can supplement the half-enclosure internal cavity into a full-enclosure configuration. The medical staff can fine-tune the circumference of the full-enclosure internal cavity by selectively buckling the female buckle 122 on the end face 121 of the free segment 120 with a certain male buckle 114 of the inner side face 130 of the zipper segment 110. Specifically, after the medical staff defines the half-enclosure internal cavity using the zipper segment 110 according to the gestational weeks of the premature infant, if the female buckle 122 is buckled with the male buckle 114 close to the end of the zipper segment 110, the circumference of the internal cavity will be increased to adapt to the premature infant with a larger upper half. Conversely, if the female buckle 122 is buckled with the male buckle 114 away from the end of the zipper segment 110, the circumference of the internal cavity will be reduced to adapt to the premature infant with a smaller upper half. This design allows the internal cavity of the nest body 100 to be finely adjusted to meet the physiological needs and body size differences of different premature infants.

[0032] Preferably, as shown in Figures 1-3 , an acute angle is configured between the end face 121 and the inner side face 130 of the free segment 120, while a blunt angle complementary to the acute angle is formed between the end face 121 and the outer side face 140 of the free segment 120. This chamfer structure ensures that the inner side face 130 of the zipper segment 110 and the inner side face 130 of the free segment 120 can achieve smooth transition when the female buckle 122 on the end face 121 of the free segment 120 is buckled with the male buckle 114 of the inner side face 130 of the zipper segment 110. The purpose of this transition design is to avoid the formation of a special-shaped structure at the connection between the zipper segment 110 and the free segment 120, which may interfere with the premature infant maintaining a normal prone position or supine position in the nest body 100. Through this special angle design, the connection between the free segment 120 and the zipper segment 110 after buckling will not form a protruding and irregular structure. This smooth transition not only improves the comfort inside the nest body 100, but also reduces the adverse effects that the improper connection structure may have on the body posture of the premature infant, thereby helping to maintain the natural body position of the premature infant in the nest body 100.

[0033] Preferably, as shown in Figures 1-3As shown, the sandwiched pad 200 comprises two layers of rectangular soft pads with matching shapes and areas. The two layers of rectangular soft pads are closed at three edges by sewing or gluing, and the other edge is kept open, forming a sandwiched pad 200 with a bag opening feature. The open edge design allows the sandwiched pad 200 to easily put in or take out the hard pad plate 220 with matching shapes and areas. The hard pad plate 220 is placed inside the sandwiched pad 200 when the premature baby needs to be turned over, aiming to provide support in the up-down direction for the nest 100. This structural design effectively avoids the problem of local indentation of the sandwiched pad 200 caused by the weight of the premature baby during the turning process, thereby preventing uncontrolled shaking of the premature baby in the cavity of the nest 100 during the turning process. By increasing the support of the pad plate 220, the sandwiched pad 200 can provide a more stable and safe support environment, helping to maintain the correct body position of the premature baby and reducing potential risks caused by instability.

[0034] Preferably, as shown in Figure 4 , Figure 5 When the premature baby needs to be repositioned, the nest 100 is designed to connect with the sandwiched pad 200 at its lower surface and connect with another sandwiched pad 200 at its upper surface, thereby achieving complete wrapping of the premature baby. After completing the body position switching from supine position to prone position or vice versa, the sandwiched pad 200 originally located below the nest 100 is turned over to the position above the nest 100. This sandwiched pad 200 will be retained, while the hard pad plate 220 contained therein will be removed. At the same time, the sandwiched pad 200 originally located above the nest 100 is turned over to the lower position. This sandwiched pad 200 will be retained, while the hard pad plate 220 inside it will be removed. After completing the body position turning, the zipper head 211 of the sandwiched pad 200 on the upper layer can move a certain distance along the second zipper tape 210 away from the zipper stop 212, to ensure that a certain gap is left between the upper sandwiched pad 200 and the nest 100, improving the gas exchange between the internal cavity of the nest and the external atmosphere, ensuring smoother breathing for the premature baby.

[0035] Preferably, in the configuration where the upper and lower surfaces of the nest body 100 are connected with the interlayer pads 200, the second zipper strips 210 of each interlayer pad 200 are connected with the first zipper strips on the upper and lower surfaces of the nest body 100 in the vertical position corresponding to each other. For example, when the second zipper strip 210 of the lower interlayer pad 200 is connected with the inner first zipper strip 111 on the lower surface of the nest body 100, the second zipper strip 210 of the upper interlayer pad 200 is also connected with the inner first zipper strip 111 on the upper surface of the nest body 100. This configuration is designed to ensure that the area of the internal cavity of the nest body 100 remains constant before and after the premature baby is turned over. This structural design not only facilitates safe and effective turning of the premature baby, but also ensures the consistency of the internal environment of the nest body 100 before and after turning, which helps to maintain the stable support and protection of the premature baby.

[0036] Preferably, as shown in Figure 1 , Figure 2 , in the design of the interlayer pad 200, the second zipper strip 210 thereon is equipped with a zipper head 211 that can move along it, used to achieve the pulling apart and engaging operation between the first and second zipper strips 210. When the interlayer pad 200 is about to be connected with the nest body 100, the position of the zipper head 211 is designed at the starting end of the second zipper strip 210 close to the female buckle 114. To prevent the zipper head 211 from accidentally slipping during use, the second zipper strip 210 is provided with a zipper stop 212 at the end of the male buckle 122. The structure of the zipper stop 212 effectively limits the movement range of the zipper head 211, ensuring the stability and safety of the zipper in the connected state, thereby providing reliable connection performance.

[0037] Preferably, as shown in Figure 1 , Figure 2 , the internal cavity of the nest is configured with a fixed pillow 300 for further stabilizing and limiting the posture of the premature baby, which includes a head pillow 310, a hug pillow 320 and a body pillow 330. The head pillow 310 is placed in the position of the head of the premature baby, whether it is in a prone position or a supine position, it can provide cushioning and protection between the forehead or the back of the head and the interlayer pad 200, ensuring safe support of the head. The hug pillow 320 is placed in front of the chest of the premature baby by the medical staff during the turning process from a supine position to a prone position. After the turning is completed, the hug pillow 320 plays a filling role, located between the chest of the premature baby and the interlayer pad 200, providing comfortable support and stability. The body pillow 330 is placed on both sides of the body of the premature baby, further ensuring the safe positioning and posture maintenance of the body of the premature baby inside the nest body 100.

[0038] Preferably, as shown in Figure 1 , Figure 2As shown, two fixing straps 400 are designed on the outer side 140 of the zipper section 110. The two ends of these fixing straps 400 are called the fixed end and the free end, respectively. The fixed end is the end of the fixing strap 400 that is fixedly connected to the outer side 140 of the zipper section 110, while the free end is the end of the fixing strap 400 that can move freely. This end can first cross the interlayer pad 200 and then be detachably connected to the outer side 140 of the zipper section 110.

[0039] Preferably, the free end of the fixing strap 400 can be provided with multiple connecting structures along its length. These connecting structures can be detachably connected to the fixing structures reserved on the outer side 140 of the zipper section 110, thereby realizing the fixing effect of the fixing strap 400 on the bird's nest (especially when turning over). To facilitate and quickly realize the detachable connection between the connecting structures on the fixing strap 400 and the fixing structures on the outer side 140 of the zipper section 110, the connecting structures and fixing structures can be structures that can detachably cooperate with each other, such as holes, rings, buckles, or Velcro. When the nest body 100 is connected to the interlayer pad 200 with the first zipper strap at different positions, the size (especially the width) of the resulting bird's nest will change. The purpose of providing multiple connecting structures on the fixing strap 400 is to enable medical personnel to select a suitable connecting structure according to the width of the bird's nest, so as to use the effective fixing length of the fixing strap 400 (i.e., the length between the selected connecting structure and the fixing end) for fixing. Specifically, selecting the connection structure closest to the free end of the fixing strap 400 will result in a longer effective fixing length of the fixing strap 400, making it more suitable for connecting the interlayer pad 200 to the outer first zipper strap 113 of the nest body 100; selecting the connection structure furthest from the free end of the fixing strap 400 will result in a shorter effective fixing length of the fixing strap 400, making it more suitable for connecting the interlayer pad 200 to the inner first zipper strap 111 of the nest body 100.

[0040] The fixing strap 400 is inelastic; its purpose is to secure the interlayer pad 200 (e.g., ...). Figure 6 (As shown). To ensure that the interlayer pad 200 has the function of allowing the preterm infant to move under elastic resistance to promote the normal development of the skeletal muscle system, the interlayer pad 200 is designed to be elastic. Although the interlayer pad 200 can provide some support for the preterm infant's turning over by adding a pad 220, in order to further ensure the safety of turning over, the fixing strap 400 can act like a seat belt, providing additional support for the preterm infant's turning over.

[0041] Preferably, the nest body 100 can be designed to contain a latex inner core and two layers of antibacterial protective cover wrapped outside. The length of the latex inner core is equal to the sum of the lengths of the zipper segment 110 and the free segment 120, and is made of natural latex material with a honeycomb air-permeable hole structure, which is designed to reduce the accumulation of heat and humidity, maintain air circulation in the bird nest, and provide a comfortable protective environment for premature babies. This structure helps to improve the air permeability and comfort of the nest body 100. Surrounding the latex inner core are two layers of antibacterial protective cover, the inner layer preferably uses bacteriostatic Dupont cloth, which has excellent antibacterial effect and can effectively inhibit the growth of harmful microorganisms. The outer layer is a low-elasticity antibacterial knitted fabric, which has air permeability and warmth, and also has a certain structural strength to support the sewing of the first zipper tape on its surface, thereby enhancing the overall stability and service life. The interlayer pad 200 in the nest body 100 is configured with antibacterial cloth on the surface in contact with the premature baby in a detachable adhesive manner. The antibacterial cloth can be made of knitted fabric, which is designed to provide better body position fixation effect when the premature baby turns over, and to ensure safety and comfort in different body positions.
