Description

Technical Field

[0001] This invention relates to the field of nursing care products, and in particular to an inflatable wearable positioning aid for paralyzed patients. Background Technology

[0002] Paralyzed patients lose the ability to move their limbs independently due to impaired nerve function. Prolonged bed rest or fixed position can easily lead to complications such as pressure sores, blood circulation disorders, and joint deformities. Early positional assistive tools were mostly handmade sponges, blankets, or foam pads with fixed shapes. They had poor support and could not flexibly adapt to different positional needs, which could easily lead to local pressure ischemia and increase the risk of pressure sores.

[0003] In the prior art, Chinese patent document CN215536153U discloses a variable inflatable positioning pad for preventing pressure injuries. This pad includes a main body, an auxiliary airbag pad, and an inner partition structure within the main body. The main body has a handle at the top and an inner partition separating the upper and lower layers. The main body has two inflation ports connected to upper and lower inflation tubes. The bottom of the main body has anti-slip textures to enhance grip during use. An adhesive patch is provided on the main body for easy adhesion and removal from the adhesive patch on the back of the auxiliary airbag pad. An auxiliary airbag is laid flat on the auxiliary airbag pad, which has an inflation port and inflation tube. This invention features a simple overall structure, achieving inflatable use through a simple inflation mechanism. It is also lightweight and easy to move, facilitating use and transport by medical personnel, thereby improving their work efficiency.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: The inflatable positioning pad is a one-piece structure, which expands completely after inflation. Although it provides support, the patient's back is pressed against the outer surface of the positioning pad. When the patient's position needs to be changed, medical staff still need to manually change it throughout the process. The inflatable positioning pad provides poor assistance. In addition, the one-piece inflatable positioning pad has poor adjustability and is not convenient to adjust according to the patient's vital signs, resulting in low overall adaptability. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing technology has the disadvantages of poor effect in assisting patients to change their body position, low assistive effect and poor adjustment performance. To this end, we propose an inflatable wearable body position assist pad for paralyzed patients.

[0006] To achieve the above objectives, this application adopts the following technical solution: an inflatable wearable positioning aid for paralyzed patients, comprising an upper airbag and a lower airbag, wherein a head airbag is provided at the end of the upper airbag, and a conduit is fixedly connected to the outer surface of the upper airbag, the lower airbag and the head airbag, and an opening and closing component is provided at the end of the conduit, an adjustment component is provided between the upper airbag and the lower airbag, and a support component is provided at the lower part of the upper airbag; The opening and closing assembly includes a hollow tube fixedly connected to the end of the conduit, a one-way air valve fixedly connected to the end of the hollow tube away from the conduit, an extension tube fixedly connected to the outer surface of the hollow tube, and a sealing plug provided inside the extension tube. The adjustment assembly includes a hollow box fixedly connected to the outer surface of the upper airbag, a shaft rotatably connected to the middle of the hollow box, a winding belt wound around the outer surface of the shaft, a ratchet movably sleeved on the outer surface of the shaft, and a pawl ring fixedly connected to the inner wall of the hollow box.

[0007] Preferably, the end of the extension tube is threadedly connected to a threaded rod, and one end of the threaded rod extending into the extension tube is fixedly connected to the sealing plug.

[0008] Preferably, a sealing groove is provided at the connection between the extension tube and the inner wall of the hollow tube, and the sealing plug is snapped onto the outer surface of the sealing groove.

[0009] Preferably, the outer surface of the extension tube has an annular array of openings, and the openings connect the extension tube and the hollow tube.

[0010] Preferably, the end of the take-up belt away from the shaft is fixedly connected to the outer surface of the lower airbag, and a spring is sleeved on the lower part of the outer surface of the shaft. The end of the spring away from the shaft is fixedly connected to the inner wall of the hollow box.

[0011] Preferably, a push rod is movably inserted at the top of the shaft, a slider is fixedly connected to the outer surface of the push rod, the end of the slider away from the push rod is fixedly connected to the inner ring of the ratchet, and a helical spring is fixedly connected to the bottom of the push rod, the end of the helical spring away from the push rod is fixedly connected to the inner wall of the shaft.

[0012] Preferably, the outer surface of the shaft is provided with a guide groove, and the slider is slidably connected inside the guide groove.

[0013] Preferably, the support assembly includes two flat plates fixedly connected to the lower surface of the upper airbag. One end of each flat plate is fixedly connected to a base, and the other end is fixedly connected to a support leg. A corrugated strip is provided between the two flat plates.

[0014] Preferably, the outer surface of the base is provided with a hook and loop surface, and the end of the support leg away from the flat plate is provided with a hook and loop surface.

[0015] Preferably, the upper airbag and the lower airbag are each provided as two pieces, and an elastic band is provided between each upper airbag or lower airbag.

[0016] The technical effects and advantages of this invention are as follows: In this invention, multiple independent airbags are set up in conjunction with the opening and closing components. The one-way air valve enables rapid inflation. Unilateral inflation allows the patient to be in a tilted side position, simplifying the position adjustment operation and reducing the difficulty of nursing care. The air pump automatically closes to prevent air leakage after separation. The threaded rod drives the sealing plug to release air, which can achieve rapid air release. Reverse rotation restores the seal, balancing the convenience of inflation and deflation with airtightness. This avoids the failure of position support due to air leakage and improves the safety and stability of the device. In this invention, the combination of a winding shaft, ratchet and pawl, and a spring allows for convenient adjustment of the distance between the upper and lower airbags. When the winding belt is stretched, the ratchet and pawl ring slide without being restricted, and after stretching, the reverse rotation is restricted to achieve locking. With the elastic band, it can accurately match the patient's body shape. When retracting, pressing the push rod unlocks the winding, greatly improving the device's adaptability to patients of different body types and enhancing its practicality. In this invention, the back support plate, after being inflated, forms a triangular structure with the base and support legs. By adjusting the angle of the support legs, the leaning posture can be flexibly adjusted, making it convenient for patients to sit and lean, and effectively reducing the nursing burden on medical staff.

Detailed Implementation

[0019] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0020] Reference Figures 1 to 7 As shown, the present invention provides a technical solution: an inflatable wearable positioning aid for paralyzed patients, including an upper airbag 1 and a lower airbag 2. A head airbag 3 is provided at the end of the upper airbag 1. The outer surfaces of the upper airbag 1, the lower airbag 2 and the head airbag 3 are all fixedly connected to a conduit 4. An opening and closing component 5 is provided at the end of the conduit 4. An adjustment component 6 is provided between the upper airbag 1 and the lower airbag 2. A support component 8 is provided at the lower part of the upper airbag 1. The upper airbag 1 and the lower airbag 2 are each made of two pieces, and an elastic band 7 is provided between each upper airbag 1 or lower airbag 2.

[0021] Beforehand, all the air inside the device is released. Then, the device is worn on the patient. The upper airbag 1 is wrapped around the patient's upper body, the lower airbag 2 is wrapped around the patient's buttocks and thighs, and the head airbag 3 is placed at the patient's neck and head. Each part can be inflated and deflated independently. Inflating one side allows the patient to be in a tilted side position, which can assist in turning over and turning to the side. The distance between the upper airbag 1 and the lower airbag 2 can be adjusted according to the patient's body size using the adjustment component 6. The opening and closing component 5 can balance the convenience of inflation and deflation with the sealing, improving the safety and stability of the device. The support component 8 can be used to flexibly adjust the leaning posture, making it convenient for the patient to sit and lean.

[0022] Reference Figures 2 to 4As shown, the opening and closing assembly 5 includes a hollow tube 51 fixedly connected to the end of the conduit 4. A one-way air valve 52 is fixedly connected to the end of the hollow tube 51 away from the conduit 4. An extension tube 53 is fixedly connected to the outer surface of the hollow tube 51. A sealing plug 55 is provided inside the extension tube 53. A threaded rod 54 is threadedly connected to the end of the extension tube 53. One end of the threaded rod 54 that extends into the extension tube 53 is fixedly connected to the sealing plug 55. A sealing groove 56 is provided at the connection between the extension tube 53 and the inner wall of the hollow tube 51. The sealing plug 55 is snapped and fitted to the outer surface of the sealing groove 56. A through-hole 57 is opened in an annular array on the outer surface of the extension tube 53. The through-hole 57 connects the extension tube 53 and the hollow tube 51.

[0023] The inflation / deflation structure design combines convenience and sealing, significantly reducing the difficulty of care and ensuring stable use. During inflation, the one-way valve 52 connects to the air pump to achieve one-way inflation. After inflation is complete, it automatically closes after separating from the air pump, simplifying the operation process and effectively avoiding air leakage when disassembling the air pump, ensuring stable pressure inside the airbag. During deflation, rotating the threaded rod 54 pushes the sealing plug 55 out of the sealing groove 56 to form a passage, allowing gas to be discharged quickly. After deflation, rotating the threaded rod 54 in the opposite direction resets the sealing plug 55 to press against the sealing groove 56, ensuring airtightness during subsequent inflation. This effectively avoids the problem of body position support failure caused by air leakage, comprehensively improving the safety and reliability of the auxiliary pad.

[0024] Reference Figure 2 , Figure 5 and Figure 6 As shown, the adjustment assembly 6 includes a hollow box 61 fixedly connected to the outer surface of the upper airbag 1. A shaft 62 is rotatably connected to the middle of the hollow box 61. A winding tape 63 is wound around the outer surface of the shaft 62. A ratchet 64 is movably sleeved on the outer surface of the shaft 62. A pawl ring 65 is fixedly connected to the inner wall of the hollow box 61. The end of the winding tape 63 away from the shaft 62 is fixedly connected to the outer surface of the lower airbag 2. A spring-loaded spring 66 is sleeved on the lower part of the outer surface of the shaft 62. The spring-loaded spring 66 is located away from the shaft 62. One end is fixedly connected to the inner wall of the hollow box 61. A push rod 67 is movably inserted through the top of the shaft 62. A slider 69 is fixedly connected to the outer surface of the push rod 67. The end of the slider 69 away from the push rod 67 is fixedly connected to the inner ring of the ratchet 64. A helical spring 610 is fixedly connected to the bottom end of the push rod 67. The end of the helical spring 610 away from the push rod 67 is fixedly connected to the inner wall of the shaft 62. A guide groove 68 is opened on the outer surface of the shaft 62. The slider 69 is limited and slidably connected inside the guide groove 68.

[0025] Pulling the airbag 2 releases the winding shaft from the shaft 62. Under the action of the tension, the shaft 62 rotates. The forward rotation of the shaft 62 drives the ratchet 64 to rotate. At this time, the ratchet 64 and the pawl ring 65 slide against each other, so the pawl ring 65 has no limit on the ratchet 64. At the same time, the rotation of the shaft 62 compresses the spring 66. The spring 66 accumulates elastic potential energy under compression, and the rebound force of the spring 66 acts on the shaft 62. However, the reverse rotation of the shaft 62 is limited by the pawl ring 65. This ensures that the pulled winding belt 63 can be locked. By stretching the belt to an appropriate length according to the patient's body shape, the size of the device can be adjusted, making the device adaptable to patients of different body shapes and improving the practicality of the device.

[0026] Reference Figure 2 and Figure 7 As shown, the support assembly 8 includes two flat plates 81 fixedly connected to the lower surface of the upper airbag 1. One end of the flat plate 81 is fixedly connected to a base 82, and the other end is fixedly connected to a support leg 83. A corrugated strip 86 is provided between the two flat plates 81. The outer surface of the base 82 is provided with a Velcro surface 84, and the end of the support leg 83 away from the flat plate 81 is provided with a Velcro hook surface 85.

[0027] The device expands synchronously through inflation, driving the flat plate 81, base 82, and support legs 83. The corrugated belt 86 can extend and retract freely. After expansion, the hook and loop fasteners 85 at the end of the support legs 83 and the hook and loop fasteners 84 on the outer surface of the base 82 are pressed and attached as needed, so that the three quickly form a stable triangular support structure. This structure can effectively support the patient's back, making it easier for the patient to sit comfortably in bed. At the same time, by adjusting the support angle of the support legs 83, the patient's posture can be flexibly changed to suit the different patient's physical tolerance and rehabilitation needs. The overall operation is simple and quick, with strong support stability, effectively improving the patient's sitting comfort and nursing convenience during bed rest, demonstrating the multifunctional characteristics of the device.

[0028] Working Principle: For the care of paralyzed patients, all the air inside the device is released beforehand. The device is then worn on the patient. The upper airbag 1 covers the patient's upper body, the lower airbag 2 covers the patient's buttocks and thighs, and the head airbag 3 is positioned around the patient's neck and head. The distance between the upper airbag 1 and the lower airbag 2 can be adjusted according to the patient's size. Pulling the lower airbag 2 releases the winding shaft from the shaft 62. Under the tension, the shaft 62 rotates. The forward rotation of the shaft 62 drives the ratchet 64 to rotate. At this time, the ratchet 64 and the pawl ring 65 slide against each other, so the pawl ring 65 has no limit to its action on the ratchet 64. Simultaneously, the rotation of the shaft 62 compresses the spring 66. The spring 66 accumulates elastic potential energy under compression, and the rebound force of the spring 66 acts on the shaft. 62, but the reverse rotation of the shaft 62 will be limited by the pawl ring 65, thus ensuring that the pulled take-up belt 63 can be locked. The appropriate length can be stretched according to the patient's body shape. With the elastic band 7, the size of the device can be adjusted so that the device can be adapted to patients of different body shapes, thus improving the practicality of the device. When it is necessary to pull back the take-up belt 63, by pressing the push rod 67, the push rod 67 slides into the shaft 62 and squeezes the helical spring 610. At the same time, the push rod 67 drives the slider 69 to slide down in the guide groove 68, which will drive the ratchet 64 to move down and separate from the pawl ring 65. After losing the limit, the shaft 62 can be rotated in the opposite direction under the action of the spring spring 66, thus achieving the effect of winding the take-up belt 63 and at the same time bringing the distance between the lower airbag 2 and the upper airbag 1 closer. Each part of the device can be independently inflated and deflated. Inflating all parts provides support for the patient. Inflating one side leaves the other side deflated, thus supporting only one side. The patient is in a tilted, sideways position supported by the unilateral airbag, facilitating lateral and turning maneuvers by medical staff to change the patient's position. The catheter 4 has a one-way valve 52 at its end. When connected to the air pump, the valve allows for one-way inflation. After inflation, it automatically closes when disconnected from the air pump, simplifying the inflation process and effectively preventing air leakage when disassembling the air pump after inflation, ensuring stable pressure within the airbag. When deflation occurs, rotating the threaded rod 54 causes it to rotate downwards along the extension tube 53 and push the sealing plug 55 out of the sealing groove 56 and into the hollow tube 51. At this time, the hollow tube 51 and the extension tube 53 form a passage. The gas inside the airbag flows into the hollow tube 51 through the conduit 4 and is finally discharged from the outlet 57 on the outer surface of the extension tube 53, achieving rapid deflation. After deflation is completed, rotating the threaded rod 54 in the opposite direction can drive the sealing plug 55 to re-press against the inner wall of the sealing groove 56, restoring the sealing state and ensuring airtightness during subsequent inflation. It combines the convenience of inflation with the reliability of sealing, greatly reducing the difficulty of operation for nursing staff, while avoiding the failure of body support due to air leakage, and improving the stability and safety of the auxiliary pad. Inflating the flat panel 81 allows the flat panel 81, base 82, and support leg 83 to expand simultaneously. After expansion, the hook side 85 of the support leg 83 is aligned with the hook side 84 of the outer surface of the base 82 and pressed into place, forming a triangular structure. This provides support for the patient's back, allowing them to sit comfortably on the bed. Furthermore, by changing the support angle of the support leg 83, the patient's leaning angle can be adjusted.

[0029] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
