Description

Technical Field

[0001] This utility model specifically relates to a three-tiered neonatal prone support device. Background Technology

[0002] Newborns are extremely fragile, and their organs are not yet fully developed, placing high demands on nursing conditions and assistive tools. To promote lung development, improve respiratory function, and reduce gastroesophageal reflux, the prone position is commonly used in clinical care. The three-step prone position is particularly effective in improving lung ventilation, raising the infant's oxygen saturation from below 90% and with significant fluctuations to 95-100%, enabling faster weaning and reducing the duration of oxygen therapy.

[0003] For example, Chinese utility model patent with publication number CN213666332U provides a three-step prone pillow for newborns, including a lower limb prone pillow body, a head prone pillow body on one side of the lower limb prone pillow body, and a chest prone pillow body between the head prone pillow body and the lower limb prone pillow body. The chest prone pillow body, the head prone pillow body and the lower limb prone pillow body are integrally formed.

[0004] However, most existing three-step prone support devices are one-piece designs, which makes it inconvenient to quickly adjust and fix the length of the steps, and cannot be applied to newborns of different heights, thus reducing their applicability. In view of this, a three-step prone support device for newborns is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a three-step prone support device for newborns. This addresses the technical problem mentioned in the background section that most existing three-step prone support devices are inconvenient to quickly adjust and fix the length of the steps, making them unsuitable for newborns of different heights and thus reducing their applicability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a three-step prone support device for newborns, comprising: The first step pillow has a second step pillow and a third step pillow stacked on its bottom in sequence. The second step pillow can slide on the bottom of the first step pillow, and the third step pillow can slide on the bottom of the second step pillow. A drive disk, rotatably disposed within the second step pillow along its axis, is connected to the first and third step pillows via a linkage assembly. This linkage assembly converts the sliding of the second step pillow into driving the rotation of the drive disk, and the rotation of the drive disk into driving the synchronous sliding of the third step pillow. A locking component is provided on the second step pillow to selectively lock or unlock the position of the drive disk.

[0007] In a preferred embodiment, the linkage component includes: Two sets of drive columns are provided, eccentrically positioned on both sides of the drive disk, and the two sets of drive columns are symmetrically arranged along the central axis of the drive disk; and Two sets of sliding frames are arranged opposite each other and are respectively located at the bottom of the first step pillow and on the surface of the third step pillow. The two sets of drive columns are slidably locked in the two sets of sliding frames.

[0008] In a preferred embodiment, the surface of the second stepped pillow is provided with a vertically penetrating arc-shaped groove, wherein a set of the drive columns are slidably engaged in the arc-shaped groove.

[0009] In a preferred embodiment, the locking component includes: The handle frame is slidably mounted on one side of the second step pillow; A locking pin is disposed on the handle frame, and multiple sets of locking grooves are spaced apart circumferentially around the drive disc; the locking pin is slidably engaged within the locking grooves. The elastic element has two ends that abut against the handle frame and the inner wall of the second step pillow, respectively.

[0010] In a preferred embodiment, a through groove is provided on one side of the first stepped pillow, and the handle frame can be slidably inserted into the through groove.

[0011] In a preferred embodiment, the bottom of the first step pillow is provided with a first support guide rail, the bottom of the second step pillow is provided with a second support guide rail, and the bottom of the third step pillow is provided with a third support guide rail. The second support guide rail is slidably disposed on the first support guide rail, and the third support guide rail is slidably disposed on the second support guide rail.

[0012] Compared with the prior art, the present invention has the following beneficial effects: When using this device, the position of the drive disc can be unlocked first by locking the locking component. Then, the second step pillow slides under the first step pillow. During the sliding process, the second step pillow controls the rotation of the drive disc through the linkage component. During the rotation of the drive disc, the third step pillow is driven to slide under the second step pillow through the linkage component, thereby quickly opening the second and third step pillows. At the same time, it is convenient to adjust the extension length of the second and third step pillows to suit the prone support of newborns of different heights. Finally, the position of the drive disc is locked by locking the locking component to prevent the extension length of the second and third step pillows from changing during the newborn's movement, which would affect the prone ventilation effect.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0016] Example: like Figure 1 , 2As shown, this utility model provides a three-step prone support device for newborns, including a first-step pillow 1, a second-step pillow 4 and a third-step pillow 13 arranged sequentially on the bottom of the first-step pillow 1, a first support rail 3 provided at the bottom of the first-step pillow 1, a second support rail 12 provided at the bottom of the second-step pillow 4, and a third support rail 15 provided at the bottom of the third-step pillow 13. The second support rail 12 is slidably mounted on the first support rail 3, and the third support rail 15 is slidably mounted on the second support rail 12.

[0017] In its initial state, the second step pillow 4 and the third step pillow 13 are in a retracted position. The second step pillow 4 can slide under the bottom of the first step pillow 1, and the third step pillow 13 can slide under the bottom of the second step pillow 4. The movement of the second step pillow 4 is supported and positioned by the cooperation of the first support rail 3 and the second support rail 12, and the third step pillow 13 is supported and positioned by the cooperation of the second support rail 12, preventing the second step pillow 4 and the third step pillow 13 from shifting their positions after sliding out. It is understood that, to ensure the comfort of using the device, the upper surfaces of the first step pillow 1, the second step pillow 4, and the third step pillow 13 are all made of flexible material.

[0018] like Figure 1 , 3 As shown in Figure 4, in this embodiment, a rotatable drive disk 6 is provided inside the second step pillow 4. The drive disk 6 is connected to the first step pillow 1 and the third step pillow 13 through a linkage component. The linkage component converts the sliding of the second step pillow 4 into the rotation of the drive disk 6, and converts the rotation of the drive disk 6 into the synchronous sliding of the third step pillow 13. The linkage component includes two sets of drive columns 7, which are eccentrically arranged on both sides of the drive disk 6. The two sets of drive columns 7 are symmetrically arranged along the axis of the drive disk 6. It also includes two sets of oppositely arranged sliding frames 14, which are respectively located at the bottom of the first step pillow 1 and on the surface of the third step pillow 13. The two sets of drive columns 7 are slidably locked in the two sets of sliding frames 14.

[0019] The second-step pillow 4 can be pulled out beyond the first-step pillow 1. During its movement, the second-step pillow 4, through the cooperation of the sliding frame 14 at the bottom of the first-step pillow 1 and one set of drive columns 7, drives the drive disc 6 to rotate. As the drive disc 6 rotates, it, through the cooperation of another set of drive columns 7 and the sliding frame 14 on the third-step pillow 13, drives the third-step pillow 13 to slide. This allows the third-step pillow 13 to slide out synchronously while the second-step pillow 4 is pulled out, enabling the rapid deployment and retraction of this three-step neonatal prone support device. Furthermore, a vertically penetrating arc-shaped groove 5 is formed on the surface of the second-step pillow 4, within which one set of drive columns 7 is slidably engaged. The rotation range of the drive disc 6 is limited by the cooperation between the arc-shaped groove 5 and the drive columns 7.

[0020] like Figure 1 , 4 As shown, in this embodiment, a locking assembly is provided on the second step pillow 4, which can selectively lock or unlock the position of the drive disk 6. The locking assembly includes a handle frame 9 slidably disposed on one side of the second step pillow 4, a locking pin 10 disposed on the handle frame 9, and multiple sets of locking grooves 8 spaced circumferentially around the drive disk 6. The locking pin 10 is slidably engaged in the locking grooves 8, and an elastic member 11 is disposed between the handle frame 9 and the inner wall of the second step pillow 4. A through groove 2 is provided on one side of the first step pillow 1, and the handle frame 9 can be slidably engaged in the through groove 2.

[0021] The locking pin 10 engages with the locking groove 8 to lock the position of the drive disc 6, preventing the second step pillow 4 and the third step pillow 13 from sliding. When the device needs to be used or the extension length of the second step pillow 4 and the third step pillow 13 needs to be adjusted, the handle frame 9 can be pulled to compress the elastic element 11, causing the locking pin 10 to disengage from the locking groove 8. Then, the handle frame 9 can be slid laterally to pull out the second step pillow 4 and the third step pillow 13, which also facilitates quick adjustment and fixation of the extension length of the second step pillow 4 and the third step pillow 13.

[0022] The specific usage and beneficial effects of this utility model are as follows: When using this device, the position lock of the drive disc 6 can be released first through the locking component. Then, the second step pillow 4 can be slid under the first step pillow 1. During the sliding process, the second step pillow 4 controls the rotation of the drive disc 6 through the linkage component. During the rotation of the drive disc 6, the third step pillow 13 is driven to slide under the second step pillow 4 through the linkage component, thereby quickly opening the second step pillow 4 and the third step pillow 13. At the same time, it is convenient to adjust the extension length of the second step pillow 4 and the third step pillow 13 to suit the prone support of newborns of different heights. Finally, the position of the drive disc 6 is locked by the locking component to prevent the extension length of the second step pillow 4 and the third step pillow 13 from changing during the newborn's activities, which would affect the prone ventilation effect.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
