Technical Field
[0001] This utility model relates to the field of medical auxiliary device technology, and more specifically, to a neonatal prone position assistive device. Background Technology
[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are used directly or indirectly on the human body. A neonatal prone positioning assist device is a medical or nursing tool specifically designed to help newborns maintain a safe prone position. It reduces the risks associated with the prone position by providing stable support and protection, while promoting the infant's physiological development.
[0003] Traditional prone positioning aids for newborns have the following shortcomings: In use, the leg length of a newborn is generally around 10-15 cm (hip to heel) for a full-term infant, but may be only 5-8 cm for a premature infant, a difference of nearly two times. Existing devices often have leg support areas designed for "average size," which can lead to problems for infants with extreme body sizes: if the legs are too short, the knees are unsupported, resulting in muscle fatigue; if the legs are too long, the feet extend beyond the edge of the device, forcing the ankle joint to flex, affecting blood circulation. Therefore, improvements are needed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 5As shown, this utility model provides a newborn prone positioning assist device, including an assist device 1. The assist device 1 includes a rectangular platform 11, an adjustment device 2 is provided at the bottom of the rectangular platform 11, and an adjustment groove 15 is provided below the rear end of the rectangular platform 11. The adjustment device 2 includes a rectangular plate 21 welded to the bottom of the rectangular platform 11, with the rear end of the rectangular plate 21 positioned below the adjustment groove 15. A clamping device 3 is provided at the rear end of the assist device 1, and the clamping device 3 includes a component that is slidably installed inside the adjustment groove 15 and located within the rectangular platform 11. A square plate 301 is placed above plate 21. Two side plates 311 are welded to the bottom of the square plate 301. The two side plates 311 are symmetrically installed on both sides of the rectangular plate 21. Sliding grooves 22 are provided on both sides of the rectangular plate 21. Rollers 312 are evenly installed on the inner side of the side plates 311. The bottom of the rollers 312 is in contact with the surface of the sliding grooves 22. A pull plate 310 is welded to the lower rear end of the square plate 301. A platform 303 is welded to the upper part of the thickness of the square plate 301. A soft pad 304 is glued to the upper part of the platform 303.
[0023] Two circular blocks 309 are welded to the bottom rear end of the square plate 301. The two circular blocks 309 are symmetrically installed. A long rod 302 that extends through the square plate 301 is welded above each of the two circular blocks 309. A movable plate 305 is movably sleeved on the outside of the long rod 302. Two platforms 313 are welded below the movable plate 305. A soft pad 314 is glued below the two platforms 313. A pull plate 306 is welded above the movable plate 305. A telescopic spring 308 is elastically installed between the upper side of the movable plate 305 and the lower side of the fixed block 307. The telescopic spring 308 is movably sleeved on the outside of the long rod 302. A fixed block 307 is welded to the top of the long rod 302. The fixed block 307 is located above the movable plate 305. When the front end of the square plate 301 is in contact with the inner side of the adjusting groove 15, the foremost roller 312 is positioned above the front end of the sliding groove 22.
[0024] In use, place the newborn on top of the rectangular platform 11, then pull the second pull plate 310, causing the pull plate 310 to move the square plate 301 outward, which in turn causes the square plate 301 to move the side plate 311 outward. The side plate 311 then causes the roller 312 to roll on the surface of the slide groove 22, thereby adjusting the soft pad 304 to the appropriate position. Next, pull the first pull plate 306, causing the pull plate 306 to move the movable plate 305 upward, which in turn causes the movable plate 305 to move upward around the long rod 302, compressing the telescopic spring 308 and causing it to deform. Then, place the newborn's legs above the soft pad 304, release the pull plate 306, and the telescopic spring 308 releases its elastic potential energy, pushing the movable plate 305 downward, causing the movable plate 305 to move the soft pad 304 outward. 314 moves downwards to clamp and fix the legs; pulling the pull plate 306 causes the pull plate 306 to move the movable plate 305 upwards, thereby squeezing the two ends of the movable plate 305 against the telescopic spring 308. When the pull plate 306 is released, the telescopic spring 308 can push the movable plate 305 downwards to cooperate with the soft pad 314 to fix the newborn's legs; when the movable plate 305 squeezes the telescopic spring 308, the telescopic spring 308 releases elastic potential energy to apply a downward elastic force to the movable plate 305. Therefore, when the pull plate 306 is released, the telescopic spring 308 will push the movable plate 305 downwards; the fixing block 307 limits the long rod 302, thereby effectively preventing the movable plate 305 from detaching from the long rod 302 due to excessive pulling of the pull plate 306.
[0025] By pulling the second pull plate 310, the soft pad 304 is adjusted to a suitable position. Then, by pulling the first pull plate 306, the movable plate 305 is lifted, and the newborn's legs are placed on top of the soft pad 304. Releasing the first pull plate 306 allows the soft pad 314 to move downwards and fix the legs. Compared with traditional newborn prone positioning aids, this newborn prone positioning aid uses the second pull plate 310 to make the roller 312 roll inside the adjustment groove 15 to adjust its position. Then, by pulling the first pull plate 306, the newborn's legs are placed on top of the soft pad 304 and clamped and fixed by the soft pad 314. This makes it easier to place newborns with different leg lengths and improves the overall practicality.
[0026] The rectangular platform 11 has a headrest plate 12 welded to its front end, a protective plate 13 welded above the headrest plate 12, a breathing hole 14 on the surface of the headrest plate 12, a head pillow 16 glued to the top of the headrest plate 12 and located inside the protective plate 13, a chest pillow 17 glued to the top of the rectangular platform 11, and shoulder pillows 18 glued to the top of the rectangular platform 11 and located on both sides of the chest pillow 17.
[0027] By placing the newborn on the rectangular platform 11, with its chest on the chest pillow 17, its sides on the shoulder pillows 18, and its head on the head pillow 16, and its mouth and nose on the breathing hole 14, the newborn can easily breathe outside air through the breathing hole 14, making it easy to place the newborn in a prone position.
[0028] The headrest 16 positions the newborn's head, while the chest pillow 17 and shoulder pillow 18 work together to position the newborn's body. A breathing hole 14 facilitates the newborn's breathing. Compared with traditional newborn prone positioning aids, this newborn prone positioning aid improves the overall comfort of the newborn through the headrest 16, chest pillow 17, and shoulder pillow 18, facilitates the newborn's breathing through the breathing hole 14, reduces the frequency of the newborn moving around due to physical discomfort, and is easy for medical staff to use.
[0029] Among them, a movable rod 19 is welded to the bottom of the rectangular platform 11, and a movable rod 23 is welded to the bottom of the rectangular plate 21.
[0030] By pushing the rectangular platform 11, the platform 11 moves the second movable rod 23 and the first movable rod 19, thereby facilitating the transfer of the newborn's position.
[0031] Working principle and usage process of this utility model:
[0032] In use, the newborn is placed on top of the rectangular platform 11. Then, the second pull plate 310 is pulled, causing the second pull plate 310 to move the square plate 301 outward. This causes the square plate 301 to move the side plate 311 outward. The side plate 311 then causes the roller 312 to roll on the surface of the slide groove 22, thereby adjusting the soft pad 304 to a suitable position. Next, the first pull plate 306 is pulled, causing the first pull plate 306 to move the movable plate 305 upward. This causes the movable plate 305 to move upward around the long rod 302, compressing the telescopic spring 308 and causing it to deform. Then, the newborn... The infant's legs are inserted above the soft pad 304. The pull plate 306 is released, causing the telescopic spring 308 to release its elastic potential energy and push the movable plate 305 downward. The movable plate 305 then moves the soft pad 314 downward to clamp and fix the legs. The newborn is placed on the rectangular platform 11, with its chest placed on the chest pillow 17, its sides placed on the shoulder pillows 18, and its head placed on the head pillow 16, with its mouth and nose placed above the breathing hole 14. This allows the newborn to breathe through the breathing hole 14 and facilitates the prone position.
