Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to inflatable restraint pads. Background Technology

[0002] In clinical practice, to prevent seriously ill patients from falling out of bed, bumping into things, scratching themselves, or causing other accidents due to weakness, impaired consciousness, or restlessness, and to prevent them from removing medical tubes or harming themselves, in order to ensure patient safety and facilitate treatment and care by medical staff, ordinary cloth straps are usually used to immobilize the patient by binding their hands, feet, chest, and shoulders, thereby controlling dangerous behaviors and preventing the patient from harming others or themselves.

[0003] Currently, while existing restraint belts provide good support for seriously ill patients, prolonged confinement to the bed can lead to poor blood circulation, bleeding, and bruising at the restraint site. Furthermore, the limited limb movement prevents patients from turning over independently, exacerbating discomfort and potentially causing joint pain over time. Therefore, there is a need for a restraint mat that provides effective restraint while also enhancing patient comfort to address these issues. Utility Model Content

[0004] In order to overcome the technical problems described in the prior art, this application provides an inflatable restraint pad.

[0005] The inflatable restraint pad provided in this application adopts the following technical solution: An inflatable restraint protective pad, comprising: An inflatable mattress that can be detachably installed on the hospital bed; An arm restraint assembly includes a plurality of inflatable arm restraint straps and a flexible connecting strap that connects each inflatable arm restraint strap to an inflatable mattress. The inflatable arm restraint straps are openable ring-shaped restraint straps used to restrain the patient's arm. A hand restraint assembly includes several inflatable wrist restraint straps, a hand protective cover, and a flexible connecting strap connecting each inflatable wrist restraint strap to an inflatable mattress. The inflatable wrist restraint straps are openable ring-shaped restraint straps used to restrain the patient's wrists, and the hand protective cover is used to protect the restrained hand. A trunk restraint assembly includes a plurality of inflatable trunk restraint straps mounted on an air mattress, the inflatable trunk restraint straps being openable arched restraint straps for restraining the patient's trunk; and A leg restraint assembly includes several inflatable leg restraint straps mounted on an inflatable mattress, the inflatable leg restraint straps being openable arched restraint straps used to restrain the patient's legs.

[0006] Furthermore, the annular constraint band is formed by detachably connecting the two ends of a long strip constraint band via a first connector.

[0007] Furthermore, the first connector includes a first connecting portion disposed at one end of the long strip constraint band and a plurality of second connecting portions disposed at intervals at the other end of the long strip constraint band. The diameter of the annular constraint band can be adjusted by selecting different second connecting portions to connect with the corresponding first connecting portions.

[0008] Furthermore, the outer side of the inflatable arm restraint strap is provided with a storage bag, and the inflatable arm restraint strap can be folded and stored in the storage bag when it is not inflated.

[0009] Furthermore, the flexible connecting strip is a double-layered strip with an adjustable length.

[0010] Furthermore, one end of the arched restraint band is fixed to the air mattress, and the other end is provided with a third connecting part. The air mattress is provided with an installation strap, and the installation strap is provided with several fourth connecting parts at intervals. The size of the arched restraint band can be adjusted by selecting different fourth connecting parts to connect with the corresponding third connecting parts.

[0011] Furthermore, the trunk restraint assembly includes at least two trunk inflatable restraint straps that are installed alternately on the air mattress. When adjacent trunk inflatable restraint straps are inflated, their middle parts on the side that are close to each other are detachably connected by a connector, and medical tubing outlets are provided at both ends.

[0012] Furthermore, the air mattress is equipped with a medical tubing protective cover located outside the two medical tubing outlets. One end of the medical tubing protective cover is fixed to the air mattress, and the other end is detachably connected to the air mattress.

[0013] Furthermore, the air mattress is equipped with recessed storage pockets at the locations where the torso inflatable restraint straps, leg inflatable restraint straps, mounting straps, and medical tubing protective covers are installed. When not in use, the torso inflatable restraint straps, leg inflatable restraint straps, mounting straps, and medical tubing protective covers are all stored in their respective storage pockets.

[0014] Furthermore, the air mattress, arm inflatable restraint straps, wrist inflatable restraint straps, torso inflatable restraint straps, and leg inflatable restraint straps are all connected to an air pump via air tubes. Sensors for monitoring restraint pressure, skin temperature, and skin oxygen saturation are installed on the inner surfaces of the arm inflatable restraint straps, wrist inflatable restraint straps, torso inflatable restraint straps, and leg inflatable restraint straps that come into contact with the patient.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. The inflatable mattress of this invention is installed on a hospital bed, and patients lying on the inflatable mattress can prevent pressure sores caused by prolonged bed rest. By installing inflatable restraint straps at different parts of the inflatable mattress to form a body protective shield, the patient's arms, hands, torso, and legs are restrained as a whole or in parts. While ensuring restraint, the patient can move within a safe range, avoiding pressure on the restrained areas and preventing disuse atrophy or stiffness of the joints due to prolonged complete restraint. Furthermore, the mattress has good breathability, improving patient comfort. In this invention, patients can choose to restrain specific areas according to their treatment needs, allowing patients to use the inflatable restraint protective mattress of this application whether lying down or sitting. 2. This invention provides storage bags on the arm restraint straps and recessed storage pockets on different parts of the mattress, allowing the inflatable restraint straps and installation straps to be stored in the storage bags or inside the inflatable mattress when not in use, ensuring convenient storage. Furthermore, the recessed storage pocket design ensures the flatness of the inflatable mattress while maintaining storage functionality, preventing pressure injuries caused by pressure when the patient's body comes into contact with the inflatable mattress. 3. This invention utilizes at least two staggered, inflatable torso restraint straps. After inflation, the straps are detachably connected at the center of their adjacent sides via connectors. Both ends have outlets for medical tubing, facilitating the replacement of drainage tubes and other medical lines. The staggered design allows medical staff to easily change dressings while standing on one side of the bed. By incorporating the torso restraint components and medical line protection shields, wounds and medical lines on the patient's torso can be protected without restricting the patient's limbs. The hand restraint components and hand protection shields ensure free finger movement while limiting the range of motion, preventing the patient from removing medical lines or scratching wounds. 4. By installing inflation tubes on the arm, wrist, torso, and leg inflatable restraint straps and connecting them to an air pump, the inflation and deflation of each strap can be controlled separately. Each strap can be used independently, making this inflatable restraint protective pad suitable for patients with different medical conditions. Sensors are installed on the inner surfaces of the arm, wrist, torso, and leg inflatable restraint straps that contact the patient, allowing for real-time monitoring of restraint pressure, skin temperature, and skin oxygen saturation. This enables timely adjustments to the inflation volume and tightness of the straps, preventing excessive tightness that could impede blood circulation. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings and examples. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0021] The following is in conjunction with the appendix Figures 1 to 5 This application will be described in further detail.

[0022] This invention provides an inflatable restraint pad, comprising: An air mattress 10 is detachably installed on the hospital bed; The arm restraint assembly includes a plurality of inflatable arm restraint straps 25 and a flexible connecting strap 26 connecting each inflatable arm restraint strap 25 to an inflatable mattress 10. The inflatable arm restraint straps 25 are openable ring-shaped restraint straps used to restrain the patient's arm. The hand restraint assembly includes several inflatable wrist restraint straps 33, hand protective covers 34, and a flexible connecting strap 26 connecting each inflatable wrist restraint strap 33 to an inflatable mattress 10. The inflatable wrist restraint straps 33 are openable ring restraint straps used to restrain the patient's wrists, and the hand protective covers 34 are used to protect the restrained hands. A trunk restraint assembly includes a plurality of inflatable trunk restraint straps 41 mounted on an air mattress 10, wherein the inflatable trunk restraint straps 41 are openable arched restraint straps for restraining the patient's trunk; and The leg restraint assembly includes a plurality of inflatable leg restraint straps 55 mounted on an inflatable mattress 10, the inflatable leg restraint straps 55 being openable arched restraint straps for restraining the patient’s legs.

[0023] like Figure 2 and Figure 4As shown, the air mattress 10 of the present invention can be detachably installed on a hospital bed, and patients lying on the air mattress 10 can prevent pressure sores caused by prolonged bed rest. By installing arm restraint components, hand restraint components, torso restraint components and leg restraint components at different parts of the air mattress 10, the arm inflatable restraint strap 25 and the wrist inflatable restraint strap 33, after being inflated, form ring restraint straps that restrain the patient's left and right arms and wrists respectively, and the torso inflatable restraint strap 41 and the leg inflatable restraint strap 55, after being inflated, form arched restraint straps that restrain the patient's torso and left and right legs respectively. This invention uses inflatable restraint straps to form a limb protective shield, providing overall or partial restraint to the patient's arms, hands, torso, and legs. This allows the patient's torso and limbs to move within a limited range of motion within the restraint space created by the arched or ring-shaped restraint straps, preventing pressure on the restrained areas. Furthermore, even after the patient's arms and wrists are restrained by the ring-shaped restraint straps, they can still move safely along the flexible connecting straps 26, avoiding disuse atrophy or stiffness caused by prolonged complete joint restraint. The good breathability also improves patient comfort. The inflatable restraint protective pad of this invention can be used to restrain specific areas according to the patient's treatment needs, allowing the patient to use the pad whether lying down or sitting.

[0024] like Figure 1 As shown, in some embodiments, the size of the inflatable mattress 10 is adapted to the size of the hospital bed. The inflatable mattress 10 is detachably installed on the hospital bed. When the patient lies on the inflated inflatable mattress 10, it can prevent pressure sores caused by prolonged bed rest. The thickness of the inflated mattress 10 is 4-6 cm. Fixing straps 11 are respectively provided on both sides of the bottom of the inflatable mattress 10 near the head and foot of the bed. One end of each fixing strap 11 is fixed to the bottom side of the inflatable mattress 10, and the other end is equipped with a buckle 12. By locking the buckles 12 on the left and right fixing straps 11, the inflatable mattress 10 can be fixed to the hospital bed. The end of the fixing strap 11 passes through and is fastened to the buckle 12. By adjusting the position of the buckle 12 on the fixing strap 11, the length of the fixing strap 11 can be adjusted, so that the inflatable mattress 10 is firmly fixed to the hospital bed. Inflatable tubes 13 are connected to the inflatable mattress 10, arm inflatable restraint straps 25, wrist inflatable restraint straps 33, torso inflatable restraint straps 41, and leg inflatable restraint straps 55. The inflatable tubes 13 extend from the bottom of the inflatable mattress 10. Each inflatable tube 13 is marked with an inflatable tube 13 label, namely mattress inflatable tube 13, arm inflatable tube 13, wrist inflatable tube 13, torso inflatable tube 13, and leg inflatable tube 13. By setting inflatable tubes 13 separately for each part, separate inflation can be achieved. During use, local inflation is performed according to the needs of the patient's restrained and protected parts.

[0025] like Figure 2 and Figure 3 As shown, in some embodiments, the arm restraint assembly includes a left upper arm restraint assembly 21, a right upper arm restraint assembly 22, a left forearm restraint assembly 23, and a right forearm restraint assembly 24 with the same structure but different installation positions, which can restrain the patient's left upper arm, right upper arm, left forearm, and right forearm respectively according to the patient's restraint needs. Figure 2 The left upper arm restraint assembly 21, right upper arm restraint assembly 22, and left forearm restraint assembly 23 are all in a folded state, while the right forearm restraint assembly 24 is in an unfolded state. Each arm inflatable restraint strap 25 is installed on the air mattress 10 at the position on the outside of the patient's arm via a flexible connecting strap 26. The length of the flexible connecting strap 26 is adjustable, and the length adjustment method is the same as the adjustment method of the fixing strap 11 on the air mattress 10. By setting the flexible connecting strap 26, the patient's arm can still make small movements within a safe range along the flexible connecting strap 26 after being restrained by the arm inflatable restraint strap 25. By adjusting the length of the flexible connecting strap 26, the range of motion of the patient's arm along the flexible connecting strap 26 after being restrained can be adjusted. While ensuring safety, it also allows the patient's joints to make appropriate movements, which not only improves the patient's comfort but also helps the patient's recovery.

[0026] like Figure 3 As shown, in some embodiments, the inflatable arm restraint band 25, after inflation, forms a ring-shaped restraint band formed by detachably connecting two ends of a long strip restraint band via a first connector 45. The first connector 45 includes a first connecting portion 27 disposed at one end of the long strip restraint band and several second connecting portions 28 spaced apart at the other end of the long strip restraint band. The diameter of the ring-shaped restraint band can be adjusted by selecting different second connecting portions 28 connected to corresponding first connecting portions 27. When the inflatable arm restraint band 25 is inflated, the second connecting portions 28 at appropriate positions can be connected to the first connecting portions 27 according to the thickness of the patient's arm, so that the left and right ends of the inflatable arm restraint band 25 are connected to form an inflatable ring that restrains the arm. The left and right upper arms and left and right forearms can be selectively fixed and restrained according to the patient's condition. The inflatable ring formed after the inflatable arm restraint band 25 not only restrains the arm but also ensures that the arm can move within a safe range within the space formed by the ring restraint band, ensuring the patient's joint extension and comfort.

[0027] like Figure 2 and Figure 3 As shown, in some embodiments, the outer side of the inflatable arm restraint strap 25 is provided with a hidden storage bag 29. When the inflatable arm restraint strap 25 is not inflated, it can be folded and stored in the storage bag 29. When in use, it can be pulled out from the storage bag 29.

[0028] In a preferred embodiment, the first connecting part 27 is a zipper A end located at one end of the long strip restraint band, and the second connecting part 28 is a zipper B end located at the other end of the long strip restraint band. By pulling the zipper A end and the zipper B end together, the arm inflatable restraint band 25 can form an inflatable ring to restrain the patient's arm.

[0029] like Figure 2 and Figure 4 As shown, in some embodiments, the hand restraint assembly includes a left-hand restraint assembly 31 and a right-hand restraint assembly 32. The wrist inflatable restraint strap 33 is installed on the air mattress 10 via a flexible connecting strap 26, allowing the patient's wrist to still move within a safe range along the flexible connecting strap 26 after being restrained. The range of motion of the patient's wrist along the flexible connecting strap 26 can be adjusted by adjusting the length of the flexible connecting strap 26. The left and right ends of the wrist inflatable restraint strap 33 are provided with a first connecting part 27 and a second connecting part 28, which are the same as those of the arm inflatable restraint strap 25. After the wrist inflatable restraint strap 33 is inflated, the first connecting parts 27 and the second connecting parts 28 at the left and right ends are connected to form an inflatable ring that restrains the wrist. The hand protective cover 34 can be directly installed on the air mattress 10 or fixedly connected to the wrist inflatable restraint strap 33. The hand protective cover 34 ensures that the hand is restrained and protected while allowing the hand joints to move freely within the hand protective cover 34, improving patient comfort. It can also prevent the hand from grasping wounds, drainage tubes, indwelling needles, etc., improving safety. As a preferred embodiment, the hand protector 34 can be configured as a spherical cover.

[0030] like Figure 2 and Figure 5As shown, in some embodiments, the trunk restraint assembly includes a trunk inflatable restraint strap 41 and a mounting strap 43 respectively installed on the left and right sides of the inflatable mattress 10 on the patient's trunk. One end of the trunk inflatable restraint strap 41 is fixed to the inflatable mattress 10, and the other end is provided with a third connecting part 42. The inflatable mattress 10 is provided with a mounting strap 43, and a plurality of fourth connecting parts 44 are provided at intervals on the mounting strap 43. The size of the arched restraint strap can be adjusted by selecting different fourth connecting parts 44 to connect with the corresponding third connecting parts 42. When the trunk inflatable restraint strap 41 is inflated, the fourth connecting parts 44 can be selected at appropriate positions to connect with the third connecting parts 42 according to the patient's body shape, so that the trunk inflatable restraint strap 41 forms an arched restraint cover to cover the patient's trunk. This can restrain the patient's trunk and protect the wounds and medical tubes on the patient's trunk without restricting the patient's limbs. At the same time, the patient's trunk can move within a safe range within the arched restraint cover formed by the trunk inflatable restraint strap 41, which can ensure the patient's comfort and blood circulation. For patients who do not require restraint and only need to cover medical lines or wounds in the torso, the arched restraint cover formed by the inflatable restraint straps can act as a blanket. The tightness of the arched restraint cover can be adjusted according to the patient's body size. The patient can turn over on their own inside the arched restraint cover without worrying about accidentally damaging wounds or medical lines in the limbs.

[0031] like Figure 4As shown in one embodiment, the trunk restraint assembly includes at least two trunk inflatable restraint straps 41 that are staggered and mounted on the air mattress 10. Adjacent trunk inflatable restraint straps 41, after inflation, are detachably connected at their midpoints on the sides closest to each other via connectors 45. Both ends are provided with medical tubing outlets 46, connecting the staggered trunk inflatable restraint straps 41 into a single unit, leaving only the outlets for the medical tubing. Medical tubing from the patient's trunk can be exited from the medical tubing outlets 46 and hung along the bed edge. Compared to using only one trunk inflatable restraint strap 41, using at least two trunk inflatable restraint straps 41 and detachably connecting them via connectors 45 facilitates the replacement of the patient's medical tubing. When replacing the medical tubing, it is only necessary to disconnect the connectors 45 to separate the adjacent trunk inflatable restraint straps 41, providing space for medical personnel to operate and replace the medical tubing, without needing to open the arched restraint straps. This makes the operation faster and more convenient, and avoids causing discomfort to the patient. By staggering the left and right sides of the torso inflatable restraint straps 41, compared to setting the torso inflatable restraint straps 41 in the same direction, it is more convenient for medical staff to change the dressings on the wounds of the patient's torso. Since the third connecting part 42 and the fourth connecting part 44 on the torso inflatable restraint straps 41 are disassembled and opened to one side, the torso inflatable restraint straps 41 fixed to one side of the inflatable mattress 10 will cover the patient's wound and make it inconvenient for medical staff to operate. By staggering the left and right sides of the torso inflatable restraint straps 41, medical staff can change the dressings on the patient without being disturbed by the torso inflatable restraint straps 41, no matter which side of the bed they stand on.

[0032] In a preferred embodiment, the third connecting part 42 is a zipper A end located at one end of the arched restraint strap, and the fourth connecting part 44 is a zipper B end spaced apart on the mounting strap 43. By pulling the zipper A end and the zipper B end together, the arm inflatable restraint strap 25 can form an arched restraint cover that encloses the patient's torso. By providing multiple spaced fourth connecting parts 44, the size of the arched restraint cover can be adjusted according to the patient's body shape and the required tightness of the restraint, so that the torso restraint assembly can not only ensure the patient's comfort but also be suitable for patients of different body types.

[0033] In a preferred embodiment, the connector 45 can be configured as a detachable connection such as a zipper or a button.

[0034] like Figure 4As shown, in some embodiments, a medical tubing protective cover 47 is installed on the air mattress 10 outside the two medical tubing outlets 46. One end of the medical tubing protective cover 47 is fixed to the air mattress 10, and the other end is detachably connected to the air mattress 10. Specifically, one end of the medical tubing protective cover 47 is fixed to the air mattress 10, and the other end is fitted with a hook-and-loop fastener 48 that can be adhered to the air mattress 10. When the medical tubing of the patient's torso exits from the medical tubing outlet 46, the hook-and-loop fastener 48 is separated from the air mattress 10, the medical tubing protective cover 47 is opened and placed over the medical tubing, and then the hook-and-loop fastener 48 is adhered to the air mattress 10, so that the medical tubing protective cover 47 forms an arc-shaped protective cover to protect the medical tubing and prevent the patient from pulling or grabbing the medical tubing.

[0035] like Figure 2 and Figure 4 As shown, in some embodiments, the leg restraint assembly includes a left thigh restraint assembly 51, a right thigh restraint assembly 52, a left calf restraint assembly 53, and a right calf restraint assembly 54 with identical structures but different installation positions. These components can restrain the patient's left thigh, right thigh, left calf, and right calf respectively according to the patient's restraint needs. One end of the inflatable leg restraint strap 55 is installed on the inflatable mattress 10 between the patient's legs, and the other end is provided with a third connecting part 42. An installation strap 43 is provided on the inflatable mattress 10 on the outer side of the patient's legs. Several fourth connecting parts 44 are spaced apart on the installation strap 43. By selecting different fourth connecting parts 44 and connecting them to the corresponding third connecting parts 42, the size of the arched restraint strap is adjusted to restrain the patient's legs. The arrangement of the third connecting parts 42 and the fourth connecting parts 44 is the same as that of the torso restraint assembly.

[0036] like Figure 4 As shown, in some embodiments, recessed storage pockets 14 are provided at the locations where the torso inflatable restraint straps 41, leg inflatable restraint straps 55, mounting straps 43, and medical tubing protective covers 47 are installed on the air mattress 10. When not in use, the torso inflatable restraint straps 41, leg inflatable restraint straps 55, mounting straps 43, and medical tubing protective covers 47 are stored in their respective storage pockets 14 and nested in the corresponding recessed positions on the air mattress 10, keeping the air mattress 10 flat. When in use, they can be pulled out from their respective storage pockets 14. The design of the recessed storage pockets 14 ensures both storage functionality and the flatness of the air mattress 10, preventing pressure injuries caused by pressure when the patient's body comes into contact with the air mattress 10.

[0037] like Figure 1 and Figure 4As shown, in some embodiments, the inflation tube 13 extends from the bottom of the air mattress 10 and connects to the inflation port 61 of the air pump 60, inflating the inflatable bands of the restrained areas via the air pump 60. The inner surfaces of the arm restraint band 25, wrist restraint band 33, torso restraint band 41, and leg restraint band 55 that contact the patient are equipped with sensors 64 for monitoring restraint pressure, skin temperature, and skin oxygen saturation. The air pump 60 is equipped with a socket 62 and a display screen 63. The sensors 64 at each location are connected to the socket 62 via monitoring wires 65, transmitting and displaying the monitored restraint pressure, skin temperature, and skin oxygen saturation information on the display screen 63. This allows for real-time monitoring of restraint pressure, skin temperature, and skin oxygen saturation, and timely adjustment of the inflation volume and tightness of each inflatable band to prevent excessive restraint from hindering blood circulation in the skin.

[0038] In a preferred embodiment, the flexible connecting strips 26 are all double-layered strips, and the monitoring wires 65 are attached to the inflation tubes 13. The inflation tubes 13 and the monitoring wires 65 at the arm and wrist are respectively wrapped in the interlayer of the flexible connecting strips 26.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the content of this specification should be included within the protection scope of the present invention.
