Description

Technical Field

[0001] This utility model relates to the field of turning-over assistive devices, and in particular to a multifunctional turning-over assistive device for neurological patients to prevent pressure sores. Background Technology

[0002] Neurological patients often remain bedridden for extended periods due to neurological dysfunction, resulting in a lack or limitation of their ability to turn over independently. This leads to continuous pressure on bony prominences (such as the sacrum, coccyx, heels, and scapula), obstructing local blood circulation. Consequently, the skin and subcutaneous tissues are prone to ulceration and necrosis due to ischemia and hypoxia. This is the core pathological mechanism of pressure ulcer formation. Regular turning can dynamically change the pressure points and restore local blood flow, making it the most direct and effective nursing measure for preventing pressure ulcers.

[0003] An existing postoperative assisted turning device (publication number: CN220495163U) has at least the following drawbacks:

[0004] In the aforementioned patent, the bed board is flipped through the cooperation of a threaded rod, a support rod, and a movable shaft. The purely mechanical structure does not require a complex electronic control system, resulting in low manufacturing costs and convenient maintenance. However, nursing staff need to manually turn the handle to complete the turning, which can easily increase physical burden, especially for patients with larger weight or stiff limbs. This can lead to low turning efficiency and inaccurate angle control. In addition, it only achieves the "turning action" and lacks other auxiliary functions. Therefore, this utility model proposes a multifunctional turning assistance device for preventing pressure sores in neurological patients to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multifunctional turning aid device for preventing pressure sores in neurological patients.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multifunctional turning assist device for preventing pressure ulcers in neurological patients includes a base plate. The top surface of the base plate is connected to two main turning plates via several hinges. A secondary rotating plate is hinged to one side of each main turning plate via two hinges. The device also includes a turning assist assembly disposed on the bottom surface of the base plate for assisting in turning neurological patients. The turning assist assembly includes several first fixing holes, all located on the bottom surface of the base plate. A second guide wheel plate is disposed inside each of the first fixing holes. Connecting holes are provided on both sides of the inner surface of each first fixing hole. A first linkage rod is movably sleeved on the inner circular wall of the connecting hole. The first linkage rod is fixedly installed to the second guide wheel plate. Two second fixing holes are located on the bottom surface of the base plate. A hinged foot is fixedly installed inside the bottom surface of each second fixing hole. A first electric push rod is hinged to the hinged foot. A first linkage plate is hinged to the outer circular wall of the telescopic shaft of the first electric push rod. The first linkage plate is fixedly installed to the first linkage rod.

[0008] As a further embodiment of this utility model, the bottom surface of the base plate has two third fixing holes. The inner sides of the third fixing holes are respectively provided with first circular through holes. The first circular through holes and the connecting holes are staggered vertically. The inner surface of the first circular through holes is movably sleeved with a second linkage rod. The outer circular wall of the second linkage rod is fixedly installed with a second linkage plate and a first guide wheel plate. The inner side of the third fixing holes is hinged with a second electric push rod. The outer circular wall of the telescopic shaft of the second electric push rod is hinged with the second linkage plate.

[0009] As a further embodiment of this utility model, the bottom surface of the main rotating plate and the bottom surface of the secondary rotating plate are respectively provided with a number of fixing grooves.

[0010] As a further embodiment of this utility model, several binding straps are fixedly installed on both sides of the base plate.

[0011] As a further embodiment of this utility model, support pads are fixedly installed on the top surfaces of the main flip plate and the secondary rotating plate, respectively.

[0012] As a further embodiment of this utility model, a fixing plate is fixedly installed on one side of the main flip plate and the secondary rotating plate respectively. A plurality of fourth fixing holes are opened on the top surface of the fixing plate. A plurality of hook and loop fasteners are fixedly installed on both sides of the support pad respectively. The hook and loop fasteners pass through the interior of the fourth fixing holes and are adhered to themselves by hook and loop fasteners.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Through the coordinated use of the base plate, main flipping plate, secondary rotating plate, first fixing hole, second fixing hole, connecting hole, and first linkage rod, the system can assist in turning the patient over. By using the first electric push rod to rotate the first linkage plate and the first linkage rod, the second guide wheel plate, main flipping plate, and secondary rotating plate will be flipped, thus realizing the turning operation without manual adjustment, saving physical strength. At the same time, it can also lift the patient to a semi-reclining position. By adjusting the stroke of the first and second electric push rods, the degree of turning and semi-reclining can be flexibly adjusted, making it highly functional. In addition, the support pad can be removed from the fourth fixing hole by disconnecting the Velcro connecting strap for easy cleaning or replacement, making it quite practical.

[0015] 2. By setting the fixing groove, the fixing groove provides more operating space for the operation of components such as the second electric push rod, the first guide wheel plate, the first electric push rod and the second guide wheel plate, thereby improving component integration and reducing the overall thickness.

[0027] Reference Figures 1-7A multifunctional turning assist device for preventing pressure sores in neurological patients includes: a base plate 1, the top surface of which is connected to two main turning plates 2 via several hinges, and a secondary rotating plate 3 hinged to one side of each main turning plate 2 via two hinges; and a turning assist component, which is disposed on the bottom surface of the base plate 1 and is used to assist in turning neurological patients. The turning assist component includes: several first fixing holes 4, all of which are formed on the bottom surface of the base plate 1, and the interior of each first fixing hole 4... A second guide wheel plate 15 is provided. Connecting holes 6 are provided on both sides of the inside of the first fixing hole 4. The inner circular wall of the connecting hole 6 is movably sleeved with the first linkage rod 7. The first linkage rod 7 is fixedly installed with the second guide wheel plate 15. Two second fixing holes 5 are provided on the bottom surface of the base plate 1. A hinge foot 10 is fixedly installed on the inner bottom surface of the second fixing hole 5. The hinge foot 10 is hinged with the first electric push rod 8. The outer circular wall of the telescopic shaft of the first electric push rod 8 is hinged with the first linkage plate 9. The first linkage plate 9 is fixedly installed with the first linkage rod 7.

[0028] In use, when it is necessary to turn the patient over, the first electric push rod 8 is activated to push the first linkage plate 9 to rotate. The rotating first linkage plate 9 drives the first linkage rod 7 to rotate. The rotating first linkage rod 7 then drives several second guide wheel plates 15 to push the bottom surface of the main flipping plate 2. The side of the second guide wheel plate 15 is provided with a rotating wheel. The rotating wheel pushes the main flipping plate 2 to flip through the hinge, thereby assisting the patient in turning over. It should be noted that when the main flipping plate 2 flips, the secondary rotating plate 3 is driven to flip through the hinge on one side of the main flipping plate 2.

[0029] In this embodiment, two third fixing holes 18 are provided on the bottom surface of the base plate 1. First circular through holes are provided on both sides of the interior of the third fixing holes 18. The first circular through holes and the connecting holes 6 are arranged alternately. The second linkage rod 14 is movably sleeved inside the first circular through hole. The second linkage plate 12 and the first guide wheel plate 13 are fixedly installed on the outer circular wall of the second linkage rod 14. The second electric push rod 11 is hinged to one side of the interior of the third fixing holes 18. The outer circular wall of the telescopic shaft of the second electric push rod 11 is hinged to the second linkage plate 12.

[0030] In use, the second electric push rod 11 is activated to push the second linkage plate 12, which in turn drives the second linkage rod 14 to rotate. The rotating second linkage rod 14 drives the first guide wheel plate 13 to push the secondary rotating plate 3 to flip, thereby causing the two secondary rotating plates 3 to flip synchronously (with the hinge between the main rotating plate 2 and the secondary rotating plate 3 as the axis). Thus, the secondary rotating plate 3 supports the patient's upper body, making him / her semi-reclined on the bed. The turning and semi-reclined range can be adjusted by adjusting the stroke of the first electric push rod 8 and the second electric push rod 11, which is convenient for use.

[0031] In this embodiment, the bottom surfaces of the main rotating plate 2 and the secondary rotating plate 3 are respectively provided with a plurality of fixing grooves 16, the plurality of fixing grooves 16 having different shapes. The second fixing hole 5, the first fixing hole 4 and the third fixing hole 18 correspond to the upper and lower shapes of the fixing grooves 16. A plurality of binding straps 17 are fixedly installed on both sides of the base plate 1. The top surfaces of the main rotating plate 2 and the secondary rotating plate 3 are respectively fixedly installed with support pads 19. A fixing plate 20 is fixedly installed on one side of the main rotating plate 2 and the secondary rotating plate 3. A plurality of fourth fixing holes 22 are provided on the top surface of the fixing plate 20. A plurality of Velcro connecting straps 21 are fixedly installed on both sides of the support pads 19. The Velcro connecting straps 21 pass through the interior of the fourth fixing holes 22 and are adhered to themselves by Velcro.

[0032] In use, the fixed groove 16 provides more operating space for components such as the second electric push rod 11, the first guide wheel plate 13, the first electric push rod 8, and the second guide wheel plate 15, thereby improving component integration and reducing overall thickness. At the same time, it should be noted that during production, the base plate 1, the main flip plate 2, and the secondary rotating plate 3 should be hollowed out, or a frame structure should be used to reduce quality and cost, as long as the structure remains unchanged.

[0033] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0034] With the base plate 1 in place, when the user needs to use the base plate 1 to care for a neurological patient, the base plate 1 is placed on the bed and tied using the Velcro straps on the binding strap 17, or by wrapping the binding strap 17 around the edge of the bed using Velcro straps. During production, connecting buckles or other methods can be set as needed. Then, a mattress or sheet is placed on top of the support pad 19, and the patient can lie down and use it.

[0035] Furthermore, when it is necessary to turn the patient over, the first electric push rod 8 is activated to push the first linkage plate 9 to rotate. The rotating first linkage plate 9 drives the first linkage rod 7 to rotate, and the rotating first linkage rod 7 in turn drives several second guide wheel plates 15 to push the bottom surface of the main flipping plate 2. The side of the second guide wheel plate 15 is provided with rotating wheels. The rotating wheels push the main flipping plate 2 to flip through the hinge, thereby assisting the patient in turning over. It should be noted that when the main flipping plate 2 flips, the hinge on one side of the main flipping plate 2 drives the secondary flipping plate 3 to flip. At the same time, two second guide wheel plates 15 are provided on both sides of the bottom of the secondary flipping plate 3 to push the bottom, ensuring that the bottom of the secondary flipping plate 3 is balanced and avoiding tilting and deformation. The other side can be flipped in the same way. After use, the first electric push rod 8 is activated to retract and reset. The support pad 19 can be removed for replacement or cleaning by disconnecting the Velcro connecting strap 21 through the fourth fixing hole 22.

[0036] Meanwhile, the second electric push rod 11 is activated to push the second linkage plate 12 to rotate the second linkage rod 14. The rotating second linkage rod 14 drives the first guide wheel plate 13 to push the secondary rotating plate 3 to flip, so that the two secondary rotating plates 3 flip synchronously (with the hinge between the main rotating plate 2 and the secondary rotating plate 3 as the axis). Thus, the secondary rotating plate 3 supports the patient's upper body so that he is semi-reclined on the bed. The turning and semi-reclined range can be adjusted by adjusting the stroke of the first electric push rod 8 and the second electric push rod 11, which is convenient for use.

[0037] This achieves the effect of assisting patients in turning over. By pushing the first linkage plate 9 and the first linkage rod 7 to rotate through the first electric push rod 8, the second guide wheel plate 15, the main flipping plate 2 and the secondary rotating plate 3 are flipped, thus realizing the turning operation. At the same time, it can also lift the patient to a semi-reclining position without manual operation, saving physical strength. By adjusting the stroke of the first electric push rod 8 and the second electric push rod 11, the range of turning over and semi-reclining can be flexibly adjusted, which is highly functional. In addition, the support pad 19 can be removed from the fourth fixing hole 22 by disconnecting the Velcro connecting strap 21, which is convenient for cleaning or replacement, making it quite practical.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
