Abstract
Description
Technical Field
[0001] The invention relates to the technical field of neonatal air cushions, and in particular to an adjustable automatically inflatable neonatal pressure injury prevention air cushion. Background Art
[0002] When a newborn is just born, it needs to be kept warm in an incubator. Because the skin of a newborn is relatively tender, when it is kept warm in the incubator, the back is in contact with the mattress in the incubator, and the skin is prone to pressure damage in the pressure-concentrated area. Therefore, medical staff are required to manually turn the newborn over every two hours. Since there are many newborns, the burden on medical staff is greater, and turning the newborn over may not be done in time.
[0003] In the prior art, newborns are automatically turned over by alternately inflating air cushions in different zones, thereby reducing the burden on medical staff. However, after turning over, the pressure is more concentrated on the downward side, so the compressed side is also prone to pressure injuries. Summary of the Invention
[0004] The purpose of the present 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 compressed side is also prone to pressure injury.
[0005] In order to achieve the above-mentioned object, the present invention provides the following technical solution: an adjustable automatically inflatable neonatal pressure injury prevention air cushion, comprising:
[0006] A separation airbag, with mirror-image adjustment air cushions on both sides capable of forming pressure difference feedback, a first bidirectional air pump being provided inside the separation airbag, and the two adjustment air cushions forming a differential inflation and deflation circuit with the outside world through the first bidirectional air pump;
[0007] A first waveguide channel includes an array of massage airbags arranged on top of the regulating air cushion and connected in series along the width direction, wherein infrared sensors are provided in the massage airbags;
[0008] A second waveguide channel includes transition airbags arranged in an array on the inner wall of the bottom of the regulating air cushion and connected in series along the width direction;
[0009] A 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 through a time-sharing control valve group to form a closed-loop air circuit;
[0010] When the unilateral regulating air cushion expands, the regulating air cushion on the other side contracts. The gas is injected into the first waveguide channel through the second bidirectional air pump for directional migration, and drives the massage airbag 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, the deformation of the massage airbag is re-triggered through the closed-loop air circuit, forming a periodic wave cycle.
[0011] Preferably, the massage airbag includes a top airbag and a telescopic airbag. The telescopic airbag is arranged in a bellows shape, and the telescopic direction is perpendicular to the top plane of the adjustment air cushion.
[0012] Preferably, the top airbag is always in an inflated state, and the infrared sensor is fixedly mounted on the bottom inner wall of the top airbag.
[0013] Preferably, the top plane of the adjustable air cushion is inclined at a preset angle to the horizontal plane.
[0014] Preferably, the cross-sectional area of the regulating air cushion gradually increases from one end close to the separating airbag to the other end.
[0015] Preferably, the side of the regulating air cushion is folded in a Z shape.
[0016] Preferably, it further comprises a supporting air cushion fixedly arranged at the bottom of the regulating air cushion, and suction cups are symmetrically arranged in a rectangular array on the outer wall of the bottom of the supporting air cushion.
[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 top of the arc-shaped soft top is bent toward the suction cup. The arc-shaped soft top and the square frame form an enclosed space, and the enclosed space is connected to the suction cup.
[0018] Preferably, the top of the arc-shaped soft top is fixedly connected to a support rod, the support rod passes through the bottom of the adjustable air cushion, and the top of the support rod is fixedly connected to a slide plate.
[0019] Preferably, a sleeve is fixedly connected to the inner wall of the top of the regulating air cushion, and the sleeve is slidably mounted on the outside of the slide.
[0020] In the above technical solution, the present invention provides an adjustable automatically inflatable neonatal pressure injury prevention air cushion, which has the following beneficial effects:
[0021] The present invention provides an adjusting air cushion, a massaging air bag and a transition air bag. When the adjusting air cushion on one side expands, the gas contracted by the adjusting air cushion on the other side is injected into the first waveguide channel through the second bidirectional air pump for directionally migrating, and drives the massage air bag 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 for reverse migration, and finally re-triggers the deformation of the massage air bag through the closed-loop air circuit to form a periodic wave cycle, thereby performing cyclic wave massage and dredging on the pressure surface of the newborn after turning over, thereby effectively avoiding pressure concentration after turning over, resulting in pressure damage to the pressure surface. Not only can precise turning over be performed by simultaneously inflating and deflating the adjusting air cushions on both sides, but also skin pressure damage caused by pressure concentration on the pressure surface after turning over can be effectively avoided, thereby effectively improving the adaptability of the device and the effect of preventing pressure damage.

[0034] In order 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 automatically inflatable neonatal pressure injury prevention air cushion comprises:
[0036] The separator airbag 4 has mirror-image regulating air cushions 2 on both sides that can form pressure difference feedback. A first bidirectional air pump 13 is provided inside the separator airbag 4. The two regulating air cushions 2 form a differential inflation and deflation circuit with the outside world through the first bidirectional air pump 13.
[0037] The first waveguide channel includes an array of massage airbags 3 arranged on top of the regulating air cushion 2 and connected in series along the width direction, and an infrared sensor 9 is provided in the massage airbags 3;
[0038] The second waveguide channel includes a transition airbag 8 arranged in an array on the inner wall of the bottom of the regulating air cushion 2 and connected in series along the width direction;
[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 to form a closed-loop air circuit;
[0040] When the unilateral regulating air cushion 2 expands, the gas of the unilateral regulating air cushion 2 is contracted and injected into the first waveguide channel through the second bidirectional air pump 14 for directional migration, and 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, and finally re-triggers the deformation of the massage airbag 3 through the closed-loop air circuit, forming a periodic wave cycle.
[0041] Specifically, when it is necessary to turn the newborn over, the medical staff starts the first two-way air pump 13 through the controller, and at the same time opens the first solenoid valve arranged on the first shunt pipe between the regulating air cushion 2 on either side and the first two-way air pump 13. The first two-way air pump 13 introduces the outside air into the regulating air cushion 2 through the first connecting pipe connected to the outside, and inflates and deforms the regulating air cushion 2 on that side, thereby pushing one side of the newborn to move as the regulating air cushion 2 expands and deforms, thereby pushing one side of the newborn to turn over to the other side, thereby achieving the purpose of automatic turning over, improving the degree of automation of the air cushion, and eliminating the need for medical staff to manually turn the newborn over every once in a while. While reducing the burden on medical staff, it effectively avoids repeated opening of the incubator to cause the newborn to repeatedly contact the external environment and become infected, thereby reducing the risk of infection.
[0042] Furthermore, while starting the first two-way air pump 13, the second two-way air pump 14 set in the regulating air cushion 2 on the other side is started, and the second solenoid valve set on the second connecting pipe between the second two-way air pump 14 and the regulating air cushion 2 is opened, so that the gas in the regulating air cushion 2 on the other side is introduced into the massage air bag 3 which is connected to the other port of the second two-way air pump 14, is located at the head end of the first waveguide channel and is arranged in an array along the length direction of the regulating air cushion 2, and the massage air bag 3 is inflated, deformed, and expanded, so that the regulating air cushion 2 on this side is contracted synchronously, thereby realizing the coordinated operation of the regulating air cushions 2 on both sides, expanding and deforming on one side to push the newborn to turn over to the other side, and contracting and deforming on the other side, thereby realizing precise turning over, avoiding the risk of unilateral pushing for turning over, which leads to neck sprain of the newborn, and further improving the success rate of turning over.
[0043] Furthermore, after turning over is completed, the inflation of the first two-way air pump 13 is stopped, and the first solenoid valve and the second solenoid valve are closed. At the same time, the third solenoid valve on the third connecting pipe between the second two-way air pump 14 and the transition airbag 8 set at the end of the second waveguide channel is opened, and the second two-way air pump 14 continues to act to continue to pump the air in the transition airbag 8 into the massage airbag 3 at the head end of the first waveguide channel. The massage airbag 3 continues to inflate, expand and deform. When the massage airbag 3 at the head end of the first waveguide channel expands to the limit state, the gas flows to the next massage airbag 3 through the fourth connecting pipe between the two adjacent massage airbags 3, and so on. The gas passes through the remaining massage airbags 3 in turn to reach the end of the first waveguide channel, and causes the massage airbags 3 to be inflated, deformed and bulged in turn, thereby causing the gas to migrate directionally through the first waveguide channel.
[0044] Furthermore, after the gas reaches the first waveguide channel, a closed-loop air path is formed through the fifth connecting tube connected between the end of the first waveguide channel and the head end of the second waveguide channel. The gas enters the transition airbag 8 at the head end of the second waveguide channel through the fifth connecting tube, and causes the transition airbag 8 to be inflated, deformed and bulged. When the transition airbag 8 at the head end expands to the limit state, the gas enters the next transition airbag 8 through the sixth connecting tube connected between the two adjacent transition airbags 8. Similarly, the gas passes through the remaining transition airbags 8 in turn and reaches the end of the second waveguide channel, thereby causing the gas to migrate in the opposite direction through the second waveguide channel and re-trigger the deformation of the massage airbag 3 through the second two-way air pump 14, forming a periodic wave cycle of the massage airbag 3, thereby massaging and clearing the pressure surface of the newborn after turning over, thereby effectively avoiding pressure concentration after turning over, resulting in pressure damage to the pressure surface, not only can accurate turning be performed by adjusting the air cushion 2 on both sides and inflating and deflating at the same time, but also effectively avoiding skin pressure damage caused by pressure concentration on the pressure surface after turning over, thereby effectively improving the adaptability of the device and the effect of preventing pressure damage.
[0045] Furthermore, by means of the massage airbags 3 arranged in an array, the pressure surface of the entire regulating air cushion 2 forms an evenly distributed airway, which enables the airflow to pass through the airway to form a ventilation effect, thereby further avoiding skin sores in newborns and further improving the overall preventive effect of the air cushion. At the same time, the infrared sensors 9 arranged in an array can monitor the local skin condition of the corresponding position, and perform thermal imaging through the imaging system, and send the data to the control system of the medical center in real time, so that medical staff can check the skin condition of each child. At the same time, the information will also be sent to the parents' mobile phones synchronously to help parents understand the skin health of their baby.
[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 bellows shape, and the telescopic direction is perpendicular to the top plane of the adjustment air cushion 2 .
[0047] Specifically, by expanding and contracting the telescopic airbag 32 in a direction perpendicular to the top plane of the regulating air cushion 2, the deformation of the telescopic airbag 32 can be guided, thereby ensuring that the massage airbag 3 forms a wave-like migration along the first waveguide channel, thereby 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, the top airbag 31 is always in an inflated state to support the newborn, so that no matter what state the pressure surface of the adjustment air cushion 2 is in, there are stable and evenly distributed air flow channels on its surface, further improving the protection effect. At the same time, it is convenient for the infrared sensor 9 to monitor the skin and ensure that the infrared sensor 9 is at a certain distance from the skin, thereby expanding the monitoring range of the infrared sensor 9 and avoiding damage to the infrared sensor 9 due to pressure, thereby extending the service life of the infrared sensor 9.
[0050] As a further embodiment of the present invention, the top plane of the adjustable air cushion 2 is tilted at a preset angle to the horizontal plane.
[0051] Furthermore, by adjusting the top plane of the air cushion 2 to be tilted at a preset angle to the horizontal plane and cooperating with the separation air bag 4, it is effectively avoided that a single air bag structure easily forms pressure concentration at the protruding part of the bone, and the pressure is dispersed, thereby further protecting the bones of the newborn, effectively avoiding the formation of pressure concentration, and improving 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 close to 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 close to the separating air bag 4 to the other end, a V-shaped support is formed with the separating air bag 4 as a whole, so that all parts of the newborn can be evenly supported when lying flat, thereby improving the comfort of the newborn when lying flat.
[0054] As a further embodiment provided by the present invention, the side edges of the adjustable air cushion 2 are folded in a Z shape.
[0055] Specifically, by adjusting the side of the air cushion 2 to be folded in a Z shape, when the air cushion 2 is inflated or contracted by inhalation, the Z-shaped folding design of the side allows the air cushion 2 to be expanded when it is inflated, and the angle between the top and bottom planes of the air cushion 2 is a preset angle, so that the air cushion 2 is expanded at a preset angle and according to a predetermined trajectory, so that the air cushion 2 is more stable when it is inflated to turn the newborn over.
[0056] Furthermore, when the other regulating air cushion 2 inhales and contracts, the Z-shaped folding structure is in a contracted state, and the angle between the top and bottom planes of the regulating air cushion 2 is a preset angle, so that the regulating air cushion 2 contracts at a preset angle along a predetermined trajectory, thereby enabling the newborn to be turned over stably by synergizing the inhalation and contraction and inflation of the two regulating air cushions 2, thereby effectively improving the stability of the air cushion when turning over.
[0057] As a further embodiment provided by the present invention, it also includes a supporting air cushion 1 fixedly arranged at the bottom of the regulating air cushion 2, and suction cups 5 are symmetrically arranged in a rectangular array on the outer wall of the bottom.
[0058] Specifically, the suction cup 5 provided at the bottom is adsorbed onto the bottom of the heat preservation box to fix the air cushion, thereby preventing the air cushion from shifting during the turning over process and improving the stability during the turning over.
[0059] As a further embodiment of the present invention, a square frame 7 is symmetrically arranged at the bottom of the supporting air cushion 1, and 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 toward the suction cup 5. The arc-shaped soft top 6 and the square frame 7 form an enclosed space, and the enclosed 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 curved soft top 6. The support rod 11 passes through the bottom of the adjustable air cushion 2. A slide 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 adjustable air cushion 2 , and the sleeve 10 is slidably mounted on the outside of the slide plate 12 .
[0062] Specifically, when the air cushion 2 on one side is inflated, the sleeve 10 fixed on the inner wall of the top of the air cushion 2 moves upward synchronously and contacts the slide 12, and pulls the slide 12 to drive the support rod 11 to move upward synchronously, thereby driving the arc top of the arc-shaped soft top 6 fixedly connected to the bottom end of the support rod 11 to move synchronously, thereby causing the arc-shaped soft top 6 to deform and flip upward, as shown in FIG. Figures 5 to 9 As shown, the volume of the enclosed space becomes larger, so that the enclosed space is in a negative pressure state, thereby evacuating the suction cup 5 connected to the enclosed space on this side, so that the suction cup 5 is adsorbed on the bottom of the insulation box, thereby avoiding the inflated side from being lifted up due to the air pressure during the inflation process, thereby causing the air cushion to be displaced, and further improving the stability of the air cushion during the inflation process.
[0063] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
