Description

Technical Field

[0001] The invention belongs to the field of medical equipment, and in particular relates to a standing bed for cerebral thrombosis rehabilitation training. Background Art

[0002] Cerebral thrombosis is a disease caused by obstruction of blood supply to the brain and death of brain nerves due to factors such as atherosclerosis of the brain's large arteries, stenosis of the brain arteries, and thrombosis of the brain. Cerebral thrombosis has obvious symptoms before the onset of the disease, such as numbness of the face, weakness of the fingers, weakness of the upper and lower limbs, headache, and unsteady walking.

[0003] Rehabilitation of ischemic stroke includes passive activities in bed during the ultra-acute phase. Generally, it means that when the patient's condition is relatively stable in the ultra-early stage, rehabilitation personnel can provide passive limb activities, that is, hemiplegic limb rehabilitation exercises. Through passive activities, the patient's limbs can promote the recovery of the patient's limbs.

[0004] The standing bed is a hospital bed developed for standing training. The bed board can be kept in a vertical position. In this way, after the patient is tied to the bed board, the electric cylinder flips the bed board, so that the patient can remain in a standing position, thus completing the standing training.

[0005] Standing training can use the patient's own body mass to stretch the triceps surae on the affected side, thereby effectively preventing foot drop and improving the ankle dorsiflexion ability on the affected side. At the same time, weight-bearing can promote blood circulation and metabolism in the lower limbs and even the whole body, which is beneficial to the prevention and treatment of lower limb muscle atrophy and osteoporosis, as well as improving the stability of the lower limbs, and effectively promoting the recovery of sensation in the affected lower limbs. After standing training, cerebrovascular rehabilitation training needs to further strengthen leg training. Existing leg training has special leg training equipment, but its relatively non-binding standing bed mostly relies on ropes to protect patients. Many patients have obvious worries and fears during use, which leads to low efficiency of leg training. So whether it can be improved on the basis of the standing bed to meet the needs of standing and appropriate leg training, so that patients can more easily accept more intensive leg training in the later stage is a problem that needs to be solved at present. Summary of the invention

DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1 to Figure 7 As shown, the present embodiment aims to provide a device that can help patients with cerebral thrombosis to achieve mild leg training on a standing bed, so as to reduce the anxiety and resistance of patients when they go directly from standing training to leg training due to less restraint.

[0025] In order to achieve the above-mentioned purpose, the standing bed for cerebral thrombosis rehabilitation training provided in this embodiment is the same as the existing standing bed, including a base frame 1 and a bed board 2, a bed board frame 21 is arranged at the bottom of the bed board 2, and at the same time, a flip mechanism is arranged between the bed board frame 21 and the base frame 1, which is used to realize the horizontal state and the vertical state of the bed board 2. The above structure is the structure of the existing common standing bed, so it is not described in detail in this embodiment.

[0026] Considering that the main reason why the standing bed can give the patient a sense of security is that the back has support, at the same time, more straps are provided on the standing bed (in order to better show other structures in the drawings of this embodiment, the schematic diagram of the straps is omitted). In order to achieve the same purpose, in this embodiment, the bed board 2 includes a head bed board 22, a chest bed board 23 and a leg bed board 24, wherein the head bed board 22 and the leg bed board 24 are fixed on the bed board frame 21, and a chest bed board 23 is also provided on the bed board 2 for keeping the chest bed board 23 in a horizontal state with the head bed board 22 and the leg bed board 24 or reciprocating on the head. The walking holding mechanism 3 between the bed board 22 and the leg bed board 24 mainly does two things. One thing is to keep the chest bed board 23, the head bed board 22 and the leg bed board 24 in a horizontal state, so that the entire bed board 2 is horizontal. The other thing is to extend the chest bed board 23 out of the horizontal plane of the head bed board 22 and the leg bed board 24 and make it reciprocate up and down. Since the patient's chest is tied to the chest bed board 23, as the chest bed board 23 reciprocates, the patient will passively do knee flexion exercises, thereby completing the preliminary training of the legs. To this end, the walking holding mechanism 3 provided in this embodiment includes a walking holding plate 31 and an upper pushing cylinder 32 and a lower pushing cylinder respectively arranged on the head bed board 22 and the leg bed board 24, the power ends of the upper pushing cylinder 32 and the lower pushing cylinder are respectively connected to the upper and lower ends of the walking holding plate 31, the walking holding plate 31 is a rectangular plate, and the upper pushing cylinder 32 and the lower pushing cylinder can be electric cylinders or electromagnetic push rods, which push the walking holding plate 31, thereby pushing out and retracting the chest bed board 23.

[0027] In order to realize reciprocating lifting, a walking motor 34 is provided on the walking holding plate 31, and a screw rod 35 is connected to the power end of the walking motor 34, and a screw rod nut seat 36 is mounted on the screw rod 35. The screw rod nut seat 36 is detachably fixed to the chest bed board 23 by bolts. In this way, the chest bed board 23 can maintain a horizontal state with the head bed board 22 and the leg bed board 24 or protrude from the head bed board 22 and the leg bed board 24 under the action of the upper pushing cylinder 32 and the lower pushing cylinder. At the same time, the chest bed board 23 can reciprocate between the head bed board 22 and the leg bed board 24 under the action of the driving motor. In this embodiment, in order to ensure the stability of lifting, guide light axes are arranged on both sides of the screw rod 35 to ensure the stability of the screw rod 35 nut.

[0028] Considering that the legs need to be restrained, a leg exoskeleton mechanism 4 is provided on the leg bed plate 24. The leg exoskeleton mechanism 4 can directly adopt the leg fixing part of the existing leg training equipment.

[0029] Considering that the main function of the standing bed is to perform standing training, in order to prevent the leg exoskeleton mechanism 4 from affecting or interfering with the legs during standing training, in this embodiment, a placement slot 241 for placing the leg exoskeleton mechanism 4 is provided on the leg bed board 24. In this way, when not in use, the leg exoskeleton mechanism 4 can be placed in the placement slot 241 to avoid interference.

[0030] Taking into account the need to minimize the impact of the leg exoskeleton mechanism 4, its structure should be able to make up for the gap created by the placement slot 241 during standing training, and at the same time, be able to restrain and guide the legs when leg training is required. To this end, in order to achieve the above-mentioned purpose, the leg exoskeleton mechanism 4 provided in this embodiment includes a left leg mechanism and a right leg mechanism arranged on the left and right sides, and the left leg mechanism and the right leg mechanism both include a base 42 arranged at the bottom of the placement slot 241, a lifting seat 41 arranged at the top of the placement slot 241, and a bending leg unit arranged between the base 42 and the lifting seat 41. In this embodiment, the base 42 is fixed to the bottom of the placement slot 241 by bolts, and the lifting seat 41 can be lifted and lowered in the placement slot 241. The lifting and lowering arrangement of the lifting seat 41 is because the legs need to be bent, so the things that restrain the legs also need to move with them, and for this reason, they need to be lifted and lowered.

[0031] There are many ways to lift the lifting seat 41, for example, by means of a slide rail or by using the method of setting a control rod 411 on its top in this embodiment, a linear bearing is set on the bed frame 21, and the control rod 411 passes through the linear bearing to achieve guiding and lifting.

[0032] The bent leg unit includes a thigh plate 45 axially connected to the lifting seat 41 and a calf plate 46 axially connected to the base 42. The thigh plate 45 and the calf plate 46 are axially connected. In this embodiment, the thigh plate 45 and the calf plate 46 are both plate-shaped, and the axial connection method is front-back axial connection, that is, part of the thigh plate 45 covers the calf plate 46 and keeps the plane of the thigh plate 45 and the calf plate 46 horizontal. The bent leg unit can be turned 90 degrees by axial connection with the lifting seat 41 and the base 42. The axial connection between the thigh plate 45 and the calf plate 46 can realize the bending of the thigh plate 45 and the calf plate 46 when they are in a vertical angle state with the leg bed board 24. It should be noted that the axial connection between the lifting seat 41 and the base 42 and the bent leg unit is divided into two parts, one part is to realize the angle change from horizontal to vertical, and the other part is to cooperate with the bending between the thigh plate 45 and the calf plate 46.

[0033] In order to change the leg movement from passive leg movement caused by the lifting and lowering of the back to actively driven passive leg movement, in this embodiment, a control rod 411 is provided on the top of the lifting seat 41, and the control rod 411 is provided in contact with the screw nut seat 36. Since the screw nut seat 36 needs to move back and forth, in this embodiment, the control rod 411 and the screw nut seat 36 are only in contact and are not connected together.

[0034] At the same time, considering that the leg exoskeleton mechanism 4 is extended out of the placement slot 241 to be able to be better turned over and kept level with the bed board 2 in a horizontal state, for this reason, in the present embodiment, a connecting seat 44 is further provided between the bent leg unit and the base 42 and the lifting seat 41, and the connecting seat 44 is to separate the two parts of the axial connection between the bent leg unit and the base 42 and the lifting seat 41. For this reason, in the present embodiment, the connecting seat 44 is L-shaped, that is, the connecting seat 44 includes a horizontal portion 441 and a vertical portion 442, wherein the vertical portion 442 is axially connected to the bent leg unit, and the axial connection between the vertical portion 442 and the bent leg unit is also a front-to-back axial connection. Since the bent leg unit needs to be pulled out For this purpose, a drawer 43 is provided on the horizontal part 441. The drawer 43 is a rectangular parallelepiped, one end of which is provided with a rotating shaft for inserting into the horizontal part 441 to realize the rotation of the horizontal part 441, and the other part is inserted into the base 42 or the lifting seat 41 to realize the pulling. For this purpose, a drawing groove 414 matching with the drawer 43 is provided between the base 42 and the lifting seat 41. In this way, when leg training is needed, the bent leg unit is pulled to pull out the drawer 43. At the same time, the bent leg unit is rotated to form a vertical angle relative to the bed board 2, and then the patient's legs are tied to the thigh board 45 and the calf board 46 respectively. In addition, the horizontal part 441 has another function, that is, a slot is provided on the lifting seat 41 and the base 42, and the horizontal part 441 can be inserted into the slot, so that the entire leg exoskeleton mechanism 4 will not rotate in a horizontal state.

[0035] Considering that the downward pressure of the screw nut seat 36 can only drive the control rod 411 to descend, the rise still needs to be driven by the patient's back. Therefore, in order to fully complete the actively driven passive leg movement, in this embodiment, a baffle 412 is also provided on the control rod 411, and a return spring 413 is provided between the baffle 412 and the bed frame 21. The return spring 413 is sleeved on the control rod 411. In this way, the active drive of the rising process is completed by the return spring 413 as a power source.

[0036] Through the above arrangement, when it is necessary to complete leg training, first untie the patient's original leg bed board 24 straps so that the legs can move, then manually pull out the bent leg unit, flip it over, bind the patient's thighs to the thigh board 45 and the calves to the calf board 46 through the straps, then drive the upper push cylinder 32 and the lower push cylinder to reset, push out the chest bed board 23, and then control the chest bed board 23 to rise and fall. Since the patient leans against the chest bed board 23, he can feel reliable, and the movement driven by the back bed board 2 allows the whole body to move in small amplitudes, thereby promoting better training and rehabilitation of the patient.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
