Description

Technical Field

[0001] The present invention relates to the technical field of medical care beds, and particularly to a retractable nursing support structure for a medical care bed. Background Art

[0002] In the field of medical care, the design of the nursing support for a care bed is directly related to the comfort of patients, the operational convenience of medical staff, and treatment safety. With the development of medical care technology, the importance of lower limb elevation nursing in fields such as postoperative rehabilitation, treatment of venous return disorders, and prevention of pressure ulcers has become increasingly prominent. By using a nursing support to elevate the lower limbs of patients, it is possible to promote the venous blood return of the lower limbs to prevent varicose veins of the lower limbs that are prone to occur in patients during long-term bed rest after surgery. However, with the diversification of medical needs, the following technical defects have gradually emerged in the existing nursing support structures and need to be optimized through innovative designs.

[0003] Most existing supports adopt a fixed or partially foldable design, such as a single-fold design for the length or height of the bed body. When stored, they still occupy a large space, which is not conducive to optimizing the ward environment. Most supports are fixed or require external components, such as U-shaped or S-shaped elevation pads, which occupy a large space and cannot be quickly retracted and extended. Although some partially foldable designs can reduce the volume, their stability is poor after being unfolded. For example, the lower limb nursing support with a hinged plate and spring locking structure used in some products is prone to shaking during use.

[0004] Therefore, there is an urgent need for a retractable and automatically adjustable nursing support structure to improve the load-bearing safety and operation efficiency, while optimizing the storage space to meet the complex needs of modern medical scenarios. Summary of the Invention

Detailed implementation method

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0035] Please refer to Figures 1 to 10 , as an embodiment of the present invention, a deployable nursing support structure for a medical nursing bed includes a bed body 1, a bed board 2 is placed on the bed body 1, a horizontally movable support 14 is provided on the bed body 1, a first support plate 3 is fixed on the support 14, and a second support plate 12 for supporting the patient's thighs is hinged on the first support plate 3. A third support plate 13 for supporting the patient's calves is hinged on the second support plate 12;

[0036] A driving mechanism is provided on the bed body 1 to drive the support 14 to reciprocate horizontally on the bed body 1;

[0037] A clamping component for limiting the support 14 when it reciprocates horizontally is provided on the bed body 1. The clamping component includes a groove body 15 fixed on the bed body 1 and a U-shaped slide plate 16 slidably clamped inside the groove body 15. The support 14 and the U-shaped slide plate 16 are fixed to each other. When the support 14 reciprocates horizontally, it will drive the U-shaped slide plate 16 to slide horizontally in the groove body 15;

[0038] The U-shaped slide plate 16 and the third support plate 13 are cooperated through a linkage structure. When the U-shaped slide plate 16 reciprocates horizontally in the groove body 15, it can drive the third support plate 13 to lift and lower upward.

[0039] In this embodiment, during use, the patient lies on the bed board 2, and the legs are placed on the second support plate 12 and the third support plate 13. A horizontally movable support 14 is provided on the bed body 1. The third support plate 13 and the second support plate 12 are respectively arranged on the support 14. The second support plate 12 is used to support the patient's thighs, and the third support plate 13 is used to support the patient's calves; a driving mechanism is provided on the bed body 1 to drive the support 14 to reciprocate horizontally on the bed body 1; a clamping component for limiting the support 14 when it reciprocates horizontally is provided on the bed body 1. The clamping component includes a groove body 15 fixed on the bed body 1 and a U-shaped slide plate 16 slidably clamped inside the groove body 15. When the support 14 reciprocates horizontally, it will drive the U-shaped slide plate 16 to slide horizontally in the groove body 15; the U-shaped slide plate 16 and the third support plate 13 are cooperated through a linkage structure. When the U-shaped slide plate 16 reciprocates horizontally in the groove body 15, it can drive the third support plate 13 to lift and lower upward.

[0040] While driving the bracket 14 to move horizontally through the driving mechanism, the length of the nursing bracket is extended, and at the same time, the third support plate 13 can be driven to lift upward. By lifting the third support plate 13, the lower limbs of the patient can be elevated to prevent lower limb edema and varicose veins in bedridden patients. At the same time, when the nursing bracket is stored, it can be folded in both the length direction and the height direction, which can minimize the space volume occupied by the nursing bracket. The present invention has the functions of length adjustment and height lifting, and can achieve the purpose of rapid expansion and contraction and reduction of occupied space.

[0041] As a further solution of the present invention, soft rubber materials are respectively fixedly adhered to the upper surfaces of the bed board 2, the first support plate 3, the second support plate 12, and the third support plate 13.

[0042] In this embodiment, soft rubber materials are respectively fixedly adhered to the upper surfaces of the bed board 2, the first support plate 3, the second support plate 12, and the third support plate 13. The bed board 2, the first support plate 3, the second support plate 12, and the third support plate 13 support the patient's limbs. The soft rubber material is soft and elastic, which can reduce the discomfort of the patient when lying and placing the limbs.

[0043] As a further solution of the present invention, the driving mechanism includes a rotating shaft 4 rotatably provided on the bed body 1. Swing arms 8 are respectively fixed at both ends of the rotating shaft 4. A slide rail 10 is fixed on the bed body 1. A slider 11 is slidably clamped on the slide rail 10. A connecting rod 9 is provided between the slider 11 and the swing arm 8. Both ends of the connecting rod 9 are respectively hinged to the swing arm 8 and the slider 11. The slider 11 is fixed to the bracket 14.

[0044] In this embodiment, when the rotating shaft 4 rotates, the swing arms 8 at both ends can be driven to rotate at the same time. The rotation of the swing arm 8 drives the connecting rod 9 to swing, so as to drive the slider 11 to move horizontally back and forth on the slide rail 10. Since the slider 11 is fixed to the bracket 14, the bracket 14 is driven to move horizontally back and forth.

[0045] As a further solution of the present invention, a motor 5 is fixed on the bed body 1. A driving gear 6 is installed on the output shaft of the motor 5. A driven gear 7 is fixed on the rotating shaft 4. The driving gear 6 is meshed with the driven gear 7.

[0046] In this embodiment, the motor 5 is electrically connected to an external power supply through a wire. Starting the motor 5 can drive the driving gear 6 to rotate. By using the meshing of the driving gear 6 and the driven gear 7, the driven gear 7 is driven to rotate. Since the driven gear 7 is fixed to the rotating shaft 4, the rotating shaft 4 can be driven to rotate.

[0047] As a further solution of the present invention, the linkage structure includes a lead screw 18, a first rotating rod 19, and a second rotating rod 20 rotatably arranged on the bracket 14. A fixed rod 26 is fixed to the bottom of the third support plate 13. A T-shaped frame 27 is arranged between the fixed rod 26 and the first rotating rod 19. Both ends of the T-shaped frame 27 are hinged to the fixed rod 26 and the first rotating rod 19 respectively. A threaded sleeve 25 is threadedly connected to the lead screw 18. An articulated rod 28 is arranged between the threaded sleeve 25 and the T-shaped frame 27. Both ends of the articulated rod 28 are hinged to the T-shaped frame 27 and the threaded sleeve 25 respectively. A rectangular through groove 17 is formed on one side of the groove body 15. The first rotating rod 19, the second rotating rod 20, and the convex rods 30 fixed on both sides of the first support plate 3 are respectively clamped inside the rectangular through groove 17 and rotatably connected to the U-shaped sliding plate 16;

[0048] The second rotating rod 20 is cooperated with the groove body 15 and the U-shaped sliding plate 16 through a first transmission mechanism. When the U-shaped sliding plate 16 slides in the groove body 15, it will drive the second rotating rod 20 to rotate itself;

[0049] The second rotating rod 20 is cooperated with the lead screw 18 through a second transmission mechanism. When the second rotating rod 20 rotates, it will drive the lead screw 18 to rotate.

[0050] In this embodiment, the second rotating rod 20 is cooperated with the groove body 15 and the U-shaped sliding plate 16 through a first transmission mechanism. When the U-shaped sliding plate 16 slides in the groove body 15, it will drive the second rotating rod 20 to rotate itself. The second rotating rod 20 is cooperated with the lead screw 18 through a second transmission mechanism. When the second rotating rod 20 rotates, it will drive the lead screw 18 to rotate. When the lead screw 18 rotates, the threaded sleeve 25 can be driven to move horizontally by the threaded cooperation between the threaded sleeve 25 and the lead screw 18, and then the articulated rod 28 can be driven to deflect to drive the T-shaped frame 27 to rotate. The third support plate 13 above the fixed rod 26 is lifted by the rotation of the T-shaped frame 27. The third support plate 13 is hinged to the second support plate 12, and the second support plate 12 is hinged to the first support plate 3, so as to drive the second support plate 12 and the third support plate 13 to be lifted simultaneously. The lower limbs of the patient are lifted by the lifting of the second support plate 12 and the third support plate 13. Through the cooperation of the bracket 14, the groove body 15, the U-shaped sliding plate 16, the lead screw 18, the articulated rod 28, the fixed rod 26, and the T-shaped frame 27, the third support plate 13 can be stably supported from the bottom, with high support stability and not prone to shaking.

[0051] As a further solution of the present invention, the first transmission mechanism includes a rack plate 21 fixed to the inner top wall of the groove body 15 and a gear 22 fixed to the end of the second rotating rod 20 and rotatably installed on the U-shaped sliding plate 16. The gear 22 meshes with the rack plate 21.

[0052] In this embodiment, when the U-shaped sliding plate 16 slides inside the trough body 15, it will drive the gear 22 to slide inside the trough body 15. Since the gear 22 meshes with the rack plate 21 and the rack plate 21 is fixed, the gear 22 will rotate on its own while sliding. When the gear 22 rotates, it will drive the second rotating rod 20 to rotate.

[0053] As a further solution of the present invention, the second transmission mechanism includes a bevel gear ring 23 fixed on the second rotating rod 20 and a bevel gear 24 fixed on the lead screw 18, and the bevel gear ring 23 meshes with the bevel gear 24.

[0054] In this embodiment, when the second rotating rod 20 rotates, it will drive the bevel gear ring 23 to rotate. Since the bevel gear ring 23 meshes with the bevel gear 24, the bevel gear 24 will rotate, and then drive the lead screw 18 to rotate.

[0055] As a further solution of the present invention, guardrails 29 are respectively and fixedly installed on both sides of the bed body 1.

[0056] In this embodiment, since the guardrails 29 are respectively and fixedly installed on both sides of the bed body 1, the guardrails 29 protect both sides of the patient's body after the patient lies on the bed body 1, preventing the patient from falling off the bed body 1.

[0057] As a further solution of the present invention, the slide rail 10 adopts an I-shaped slide rail, the slider 11 adopts an I-shaped slider, and the outer dimension of the slide rail 10 is adapted to the inner dimension of the slider 11.

[0058] In this embodiment, the slider 11 is movably clamped on the slide rail 10, and the slider 11 can slide horizontally on the slide rail 10 without falling off.

[0059] The working principle of the invention is as follows: When in use, the patient lies on the bed board 2, with the legs placed on the second support plate 12 and the third support plate 13. A horizontally movable bracket 14 is provided on the bed body 1. The third support plate 13 and the second support plate 12 are respectively arranged on the bracket 14. The second support plate 12 is used to support the patient's thighs, and the third support plate 13 is used to support the patient's calves. A driving mechanism is provided on the bed body 1. Starting the motor 5 can drive the driving gear 6 to rotate. The driving gear 6 meshes with the driven gear 7 to drive the driven gear 7 to rotate. Since the driven gear 7 is fixed to the rotating shaft 4, the rotating shaft 4 can be driven to rotate. The rotation of the rotating shaft 4 can simultaneously drive the swing arms 8 at both ends to rotate. The rotation of the swing arms 8 drives the connecting rod 9 to swing, thereby driving the slider 11 to reciprocate horizontally on the slide rail 10. The slider 11 is fixed to the bracket 14, thus driving the bracket 14 to reciprocate horizontally. When the bracket 14 reciprocates horizontally, it drives the U-shaped slide plate 16 to slide horizontally in the groove body 15. The U-shaped slide plate 16 and the third support plate 13 are matched through a linkage structure. When the U-shaped slide plate 16 reciprocates horizontally in the groove body 15, it can drive the third support plate 13 to lift and lower upward.

[0060] The present invention drives the bracket 14 to move horizontally through the driving mechanism, while stretching the length of the nursing bracket and driving the third support plate 13 to lift upward. By lifting the third support plate 13, the lower limbs of the patient are elevated to prevent lower limb edema and varicose veins in bedridden patients. At the same time, when the nursing bracket is stored, it can be folded and stored in both the length direction and the height direction.

[0061] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of the present invention, all technical solutions that can implement the present invention in other specific forms are included in the present invention.
