Description

Technical Field

[0001] This invention relates to the field of neonatal air cushion technology, specifically to an adjustable, automatically inflatable neonatal air cushion designed to prevent pressure injury. Background Technology

[0002] Newborns need to be kept warm in an incubator immediately after birth. Because newborns have delicate skin, their backs are in close contact with the mattress inside the incubator, creating a concentrated pressure area that can easily cause pressure injuries. Therefore, medical staff need to manually turn the newborns over every two hours. Due to the large number of newborns, the workload for medical staff is heavy, and there may be instances where turning them over is not done in a timely manner.

[0003] In existing technologies, newborns are automatically turned over by alternating inflation of air cushions in sections, which reduces the burden on medical staff. However, after turning over, the pressure is more concentrated on the downward side, so the pressure side is also prone to pressure injury. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable, automatically inflatable neonatal pressure injury prevention air cushion to solve the technical problem in the prior art that, after turning over, the pressure is more concentrated on the downward side, so the pressure side is also prone to pressure injury.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable, automatically inflatable neonatal pressure injury prevention air cushion, comprising:

[0006] The airbag is divided into two sides, which are provided with mirror-shaped adjustment air cushions that can form pressure difference feedback. The airbag is equipped with a first bidirectional air pump. The two adjustment air cushions form a differential inflation and deflation circuit with the outside through the first bidirectional air pump.

[0007] The first waveguide channel includes massage airbags arranged in an array on the top of the adjustment air cushion and connected in series along the width direction of the air path, wherein an infrared sensor is provided inside the massage airbags;

[0008] The second waveguide channel includes a transition airbag arrayed on the inner wall of the bottom of the regulating air cushion and connected in series along the width direction of the air passage.

[0009] The second bidirectional air pump is connected to the inner cavity of the regulating air cushion, the first end of the second waveguide channel and the end of the first waveguide channel simultaneously through a time-sharing control valve group, forming a closed-loop air circuit.

[0010] When one side of the adjustable air cushion expands, the gas from the other side contracts and is injected into the first waveguide channel via the second bidirectional air pump for directional migration, driving the massage airbag to generate a unidirectional deformation wave. The deformation wave is transmitted to the end via the first waveguide channel and then enters the second waveguide channel for reverse migration. Finally, it triggers the deformation of the massage airbag again through the closed-loop air path, forming a periodic wave cycle.

[0011] Preferably, the massage airbag includes a top airbag and a telescopic airbag, wherein the telescopic airbag is arranged in a corrugated tube shape and the telescopic direction is perpendicular to the top plane of the adjustment airbag.

[0012] Preferably, the top airbag is always in an inflated state, and the infrared sensor is fixedly installed on the inner wall of the bottom of the top airbag.

[0013] Preferably, the top plane of the adjusting air cushion is tilted at a preset angle to the horizontal plane.

[0014] Preferably, the cross-sectional area of ​​the regulating air cushion gradually increases from one end near the dividing airbag to the other end.

[0015] Preferably, the sides of the regulating air cushion are arranged in a Z-shape fold.

[0016] Preferably, it also includes a support air cushion fixedly disposed at the bottom of the adjustment air cushion, with suction cups arranged symmetrically in a rectangular array on its bottom outer wall.

[0017] Preferably, a square frame is symmetrically arranged at the bottom of the supporting air cushion, and an arc-shaped soft top is arranged inside the square frame. The arc-shaped soft top is bent towards the suction cup, and the arc-shaped soft top and the square frame form a sealed space, which is connected to the suction cup.

[0018] Preferably, a support rod is fixedly connected to the top of the arc-shaped soft top, the support rod passes through the bottom of the adjusting air cushion, and a sliding plate is fixedly connected to the top of the support rod.

[0019] Preferably, a sleeve is fixedly connected to the inner wall of the top of the adjusting air cushion, and the sleeve is slidably fitted onto the outside of the slide plate.

[0020] In the above technical solution, the adjustable automatic inflatable neonatal pressure injury prevention air cushion provided by the present invention has the following beneficial effects:

[0021] This invention utilizes adjustable air cushions, massage airbags, and transition airbags. When one adjustable air cushion inflates, the other adjustable air cushion contracts, and the gas is injected into the first waveguide channel via a second bidirectional air pump for directional migration. This drives the massage airbag to generate a unidirectional deformation wave. The deformation wave is transmitted through the first waveguide channel to its end, then enters the second waveguide channel for reverse migration. Finally, it re-triggers the deformation of the massage airbag through a closed-loop air path, forming a periodic wave cycle. This provides a cyclical wave massage to unblock the pressure surface of the newborn after turning over, effectively preventing pressure concentration and pressure injury. The invention not only enables precise turning by simultaneously inflating and deflating the adjustable air cushions on both sides, but also effectively prevents pressure injury to the skin caused by pressure concentration after turning over, thus significantly improving the device's adaptability and its effectiveness in preventing pressure injury.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-9 As shown, an adjustable, self-inflating neonatal pressure injury prevention air cushion includes:

[0036] The partition airbag 4 has mirror-shaped adjustable air cushions 2 on both sides that can form pressure difference feedback. The partition airbag 4 is equipped with a first bidirectional air pump 13. The two adjustable air cushions 2 form a differential inflation and deflation circuit with the outside through the first bidirectional air pump 13.

[0037] The first waveguide channel includes massage airbags 3 arranged in an array on the top of the adjustment air cushion 2 and connected in series along the width direction of the air path. An infrared sensor 9 is provided inside the massage airbags 3.

[0038] The second waveguide channel includes a transition airbag 8 arrayed on the inner wall of the bottom of the regulating airbag 2 and connected in series along the width direction of the air passage;

[0039] The second bidirectional air pump 14 is connected to the inner cavity of the regulating air cushion 2, the first end of the second waveguide channel and the end of the first waveguide channel through a time-sharing control valve group, forming a closed-loop air circuit.

[0040] When one side of the adjustable air cushion 2 expands, the gas from the other side of the adjustable air cushion 2 contracts and is injected into the first waveguide channel through the second bidirectional air pump 14 for directional migration. This drives the massage airbag 3 to generate a unidirectional deformation wave. After the deformation wave is transmitted to the end through the first waveguide channel, it enters the second waveguide channel and migrates in the opposite direction. Finally, it triggers the deformation of the massage airbag 3 again through the closed-loop air path, forming a periodic wave cycle.

[0041] Specifically, when it is necessary to turn a newborn over, medical staff activate the first bidirectional air pump 13 through the controller and simultaneously open the first solenoid valve on the first diversion pipe between the adjustable air cushion 2 on either side and the first bidirectional air pump 13. The first bidirectional air pump 13 introduces outside air into the adjustable air cushion 2 through the first connecting pipe connected to the outside, causing the adjustable air cushion 2 on that side to inflate and deform. This pushes one side of the newborn to move as the adjustable air cushion 2 expands and deforms, thereby pushing the newborn's side to turn to the other side, achieving the purpose of automatic turning over. This improves the automation level of the air cushion, eliminating the need for medical staff to manually turn the newborn over every once in a while, reducing the burden on medical staff, and effectively avoiding repeated opening of the incubator, which would cause repeated contact between the newborn and the external environment and thus reduce the risk of infection.

[0042] Furthermore, while activating the first bidirectional air pump 13, the second bidirectional air pump 14 installed in the other side of the adjusting air pad 2 is activated, and the second solenoid valve installed on the second connecting pipe between the second bidirectional air pump 14 and the adjusting air pad 2 is opened. This allows the gas in the other side of the adjusting air pad 2 to be introduced into the massage airbag 3, which is connected to the other port of the second bidirectional air pump 14, located at the beginning of the first waveguide channel, and arranged in an array along the length of the adjusting air pad 2. The massage airbag 3 is then inflated and deformed, causing the adjusting air pad 2 on that side to contract synchronously. This allows the two adjusting air pads 2 to work together, with one side expanding and deforming to push the newborn to the other side while the other side contracts and deforms, thus achieving precise turning over and avoiding the risk of neck sprains caused by unilateral pushing during turning over, thereby further improving the success rate of turning over.

[0043] Furthermore, after the turning over is completed, the inflation of the first bidirectional air pump 13 is stopped, and the first and second solenoid valves are closed. At the same time, the third solenoid valve on the third connecting pipe between the second bidirectional air pump 14 and the transition airbag 8 at the end of the second waveguide channel is opened. The second bidirectional air pump 14 continues to operate, drawing air from the transition airbag 8 into the massage airbag 3 at the beginning of the first waveguide channel. The massage airbag 3 continues to inflate and expand. When the massage airbag 3 at the beginning of the first waveguide channel expands to its limit, the gas flows through the fourth connecting pipe between two adjacent massage airbags 3 to the next massage airbag 3, and so on. The gas passes through the remaining massage airbags 3 in sequence to reach the end of the first waveguide channel, causing the massage airbags 3 to inflate and expand in sequence, thereby allowing the gas to migrate directionally through the first waveguide channel.

[0044] Furthermore, after the gas reaches the first waveguide channel, it forms a closed-loop air path through the fifth connecting pipe connecting the end of the first waveguide channel and the beginning of the second waveguide channel. The gas enters the transition airbag 8 at the beginning of the second waveguide channel through the fifth connecting pipe, causing the transition airbag 8 to inflate and deform. When the transition airbag 8 at the beginning expands to its limit, the gas enters the next transition airbag 8 through the sixth connecting pipe connecting two adjacent transition airbags 8, and so on. The gas passes through the remaining transition airbags 8 in sequence and reaches the end of the second waveguide channel, thus causing the gas to migrate in the reverse direction through the second waveguide channel. The second bidirectional air pump 14 then triggers the deformation of the massage airbag 3, forming a periodic wave cycle of the massage airbag 3. This massages and unblocks the pressure surface of the newborn after turning over, effectively preventing pressure concentration after turning over and causing pressure injury to the pressure surface. It not only allows for precise turning by simultaneously inflating and deflating the airbags 2 on both sides, but also effectively prevents skin pressure injury caused by pressure concentration after turning over, thereby effectively improving the adaptability of the device and the effect of preventing pressure injury.

[0045] Furthermore, the array of massage airbags 3 creates evenly distributed air channels on the pressure surface of the entire adjustable air cushion 2, allowing airflow to pass through and creating a ventilation effect. This further prevents skin sores in newborns and enhances the overall preventative effect of the air cushion. Simultaneously, the array of infrared sensors 9 monitors the local skin condition at corresponding locations and performs thermal imaging through the imaging system. The data is then sent to the control system of the medical center in real time, allowing medical staff to view the skin condition of each child. The information is also simultaneously sent to parents' mobile phones to help them understand their baby's skin health.

[0046] As a further embodiment of the present invention, the massage airbag 3 includes a top airbag 31 and a telescopic airbag 32. The telescopic airbag 32 is arranged in a corrugated tube shape and the telescopic direction is perpendicular to the top plane of the adjustment airbag 2.

[0047] Specifically, by expanding and contracting the telescopic airbag 32 in a direction perpendicular to the top plane of the adjusting air cushion 2, the deformation of the telescopic airbag 32 can be guided, thereby ensuring that the massage airbag 3 migrates in a wave-like manner along the first waveguide channel, thus improving the massage effect.

[0048] As a further embodiment of the present invention, the top airbag 31 is always in an inflated state, and the infrared sensor 9 is fixedly installed on the bottom inner wall of the top airbag 31.

[0049] Furthermore, by ensuring that the top airbag 31 is always inflated, it supports the newborn, thus ensuring that the pressure surface of the adjustable air cushion 2 has a stable and evenly distributed airflow channel regardless of its state, thereby further improving the protective effect. At the same time, it facilitates the infrared sensor 9 to monitor the skin and ensures that the infrared sensor 9 is at a certain distance from the skin, thereby expanding the monitoring range of the infrared sensor 9 and preventing the infrared sensor 9 from being damaged by pressure, thus extending the service life of the infrared sensor 9.

[0050] As a further embodiment of the present invention, the top plane of the air cushion 2 is tilted at a preset angle to the horizontal plane.

[0051] Furthermore, by tilting the top plane of the adjustable air cushion 2 at a preset angle to the horizontal plane and cooperating with the dividing airbag 4, the pressure concentration at the bony prominence is effectively avoided by the single airbag structure, and the pressure is dispersed to further protect the newborn's bones, effectively avoid pressure concentration, and improve the practicality of the air cushion.

[0052] As a further embodiment of the present invention, the cross-sectional area of ​​the adjustable air cushion 2 gradually increases from one end near the separating airbag 4 to the other end.

[0053] Specifically, by gradually increasing the cross-sectional area of ​​the adjusting air cushion 2 from one end near the separating airbag 4 to the other, it forms a V-shaped support with the separating airbag 4 as a whole, so that the newborn can receive uniform support in all parts when lying flat, thus improving the newborn's comfort when lying flat.

[0054] As a further embodiment of the present invention, the side of the adjustable air cushion 2 is arranged in a Z-shape fold.

[0055] Specifically, by adjusting the side of the air cushion 2 to be Z-shaped folded, when the air cushion 2 is inflated or deflated, the Z-shaped folded structure unfolds during inflation, and the angle between the top and bottom planes of the air cushion 2 is at a preset angle. This allows the air cushion 2 to unfold at a preset angle and along a predetermined trajectory, making the air cushion 2 more stable when the newborn is turned over.

[0056] Furthermore, when the other adjustable air cushion 2 inhales and contracts, the Z-shaped folding structure contracts, and the angle between the top and bottom planes of the adjustable air cushion 2 is at a preset angle. This allows the adjustable air cushion 2 to contract at a preset angle along a predetermined trajectory. By having the two adjustable air cushions 2 work together to inhale and contract and inflate, the newborn can be turned over stably, effectively improving the stability of the air cushion during turning.

[0057] As a further embodiment of the present invention, it also includes a support air cushion 1 fixedly disposed at the bottom of the adjustment air cushion 2, wherein suction cups 5 are symmetrically arranged in a rectangular array on the bottom outer wall.

[0058] Specifically, the air cushion is fixed in place by suction cup 5 at the bottom, which adheres to the bottom of the insulated box, thus preventing the air cushion from shifting position during the turning process and improving the stability of the turning.

[0059] As a further embodiment of the present invention, a square frame 7 is symmetrically arranged at the bottom of the inner side of the supporting air cushion 1. An arc-shaped soft top 6 is arranged inside the square frame 7. The arc top of the arc-shaped soft top 6 is bent towards the suction cup 5. The arc-shaped soft top 6 and the square frame 7 form a sealed space, and the sealed space is connected to the suction cup 5.

[0060] As a further embodiment of the present invention, a support rod 11 is fixedly connected to the top of the arc-shaped soft top 6, the support rod 11 passes through the bottom of the adjusting air cushion 2, and a sliding plate 12 is fixedly connected to the top of the support rod 11.

[0061] As a further embodiment of the present invention, a sleeve 10 is fixedly connected to the inner wall of the top of the adjusting air cushion 2, and the sleeve 10 is slidably sleeved on the outside of the slide plate 12.

[0062] Specifically, when the adjustable air cushion 2 on one side inflates, the sleeve 10, which is fixedly installed on the inner wall of the top of the adjustable air cushion 2, moves upward synchronously and contacts the sliding plate 12. This pulls the sliding plate 12, causing the support rod 11 to move upward synchronously. This, in turn, causes the apex of the arc-shaped soft top 6, which is fixedly connected to the bottom of the support rod 11, to move synchronously, thus deforming the arc-shaped soft top 6 and causing it to flip upwards. Figures 5 to 9 As shown, this increases the volume of the sealed space, creating a negative pressure state within the sealed space. This allows the suction cup 5, which is connected to the sealed space on this side, to be drawn out, causing the suction cup 5 to adhere to the bottom of the insulation box. This prevents the inflated side from tilting up due to air pressure during inflation, thus avoiding displacement of the air cushion and further improving the stability of the air cushion during inflation.

[0063] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
