Description

Technical Field

[0001] The present application relates to the technical field of inflatable cushions for hemiplegic patients, and specifically to an inflatable cushion specially used for early good limb positioning of hemiplegic patients. Background Art

[0002] The air cushion is an air suspended bed. Hemiplegia refers to paralysis of the upper and lower limb muscles on the same side. Good limb position is one of the important measures for early anti-spasm. This good limb position can make the joints after hemiplegia relatively stable, and can effectively prevent the typical spasm pattern of the upper limb flexors and lower limb extensors. It is also one of the methods to prevent the occurrence of pathological movement patterns in the future.

[0003] The inflatable cushions in the prior art are generally of one-piece design, which cannot provide certain effects if good limb positioning is required to ensure the limb's mobility. The local position of the inflatable cushion cannot be adjusted according to the patient's actual situation, which limits the scope of use of the inflatable cushion, narrows the scope of use of the inflatable cushion, and reduces the practicality of the inflatable cushion. Therefore, we propose an inflatable cushion specifically for early good limb positioning of hemiplegic patients to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 In this embodiment, an inflatable cushion specially used for early good limb positioning of hemiplegic patients includes an inflatable cushion body 1 and a pillow 4. An adjustment mechanism is arranged on the outside of the inflatable cushion body 1. Support plates 2 are fixedly installed on the left and right sides of the inflatable cushion body 1. A rotating shaft 3 is rotatably installed between the opposite sides of the two support plates 2. The pillow 4 is fixedly installed on the outer surface of the rotating shaft 3. A pelvic pad 5 is fixedly installed on the front side of the inflatable cushion body 1. An arm pad 6 is fixedly installed on the front side of the pelvic pad 5. A leg pad 7 is fixedly installed on the front side of the inflatable cushion body 1.

[0023] The leg pad 7 is located below the pelvic pad 5 and the arm pad 6, so that the leg pad 7 can support the lower limbs, thereby better allowing the ankle joint to maintain a 90-degree angle.

[0024] The size of the pelvic pad 5 is larger than that of the arm pad 6 , so that the arm pad 6 can support the elbow, so that the elbow can be straightened, the back of the wrist can be straightened, and the fingers can be straightened and placed on the arm pad 6 .

[0025] It should be noted that the pelvic pad 5 can support the patient's side buttocks, and its function is to prevent the pelvis from retracting and the lower limbs from externally rotating, thereby achieving a better fixation effect.

[0026] Specifically, by providing an adjustment mechanism, the height of the pillow 4 can be adjusted, so that when the pillow 4 supports the patient's bilateral shoulder joints, the bilateral shoulder joints can be raised, and the height of the pillow 4 can be adjusted according to the patient's actual situation. By providing the pelvic pad 5, the arm pad 6 and the leg pad 7 for coordinated use, the purpose of protecting the patient's upper limbs, side buttocks and lower limbs is achieved, thereby avoiding problems caused by long-term placement.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the adjustment mechanism includes two electric push rods 801 fixedly installed on the front side of the inflatable cushion body 1, and a baffle 802 is fixedly installed on the top of the two electric push rods 801. A fixing frame 803 is fixedly installed on the top of the inflatable cushion body 1, and a motor 804 is fixedly installed on the right side of the fixing frame 803. The output shaft of the motor 804 is fixedly installed with a support rod 805 through a coupling, and one end of the support rod 805 passes through and extends to the outside of the fixing frame 803. A gear 806 is fixedly installed on the outer surface of the support rod 805. A connecting rod 807 is movably installed on the front side of the inflatable cushion body 1, and a disk 808 is rotatably installed on the left side of the connecting rod 807. A rack column 809 is fixedly installed on the rear side of the connecting rod 807, and the outer surface of the rack column 809 is meshed with the outer surface of the gear 806. A limiting rod 810 is fixedly installed on the front side of the inflatable cushion body 1.

[0028] The outer surface of the disk 808 is pressed against the rear side of the pillow 4, so that the disk 808 can drive the pillow 4 to rotate, so that the angle of the pillow 4 can be adjusted according to the actual condition of the patient.

[0029] Among them, a limit block is fixedly installed on the rear side of the connecting rod 807, and the outer surface of the limit block is slidably connected to the outer surface of the limit rod 810, which plays a role in supporting the connecting rod 807, so that the connecting rod 807 can be more stable when moving up and down.

[0030] It should be supplemented that, after the height of the pillow 4 is adjusted, the connecting rod 807 can support the pillow 4 so that the pillow 4 maintains the adjusted height.

[0031] Among them, motor 804 is miniature, and the output shaft direction of motor 804 is to the left. The electrical components appearing in the utility model are all electrically connected to the external main controller, and the main controller can be a conventional known device for control such as a computer. The circuits and controls involved in the utility model are all existing technologies and will not be elaborated on here.

[0032] Specifically, by setting up the coordination between the electric push rod 801 and the baffle 802, the height of the baffle 802 can be adjusted, so that the baffle 802 can resist feet of different sizes, thereby allowing the ankle joint to maintain a ninety degree angle to avoid foot drop. By setting up the coordination between the fixing frame 803, the motor 804, the support rod 805, the gear 806, the connecting rod 807, the disc 808, the rack column 809 and the limiting rod 810, the purpose of adjusting the height of the pillow 4 is achieved, so that the height of the pillow 4 can be adjusted according to the actual situation of the patient, thereby preventing the patient's bilateral shoulder joints from retracting, and making the fixation effect better.

[0033] The working principle of the above embodiment is:

[0034] When the height of the pillow 4 needs to be adjusted, the motor 804 is first started, so that the motor 804 drives the support rod 805 to rotate clockwise, and the support rod 805 drives the gear 806 to rotate clockwise, and the gear 806 drives the rack column 809 to move upward, so that the rack column 809 drives the connecting rod 807 to move upward, and the connecting rod 807 drives the disc 808 to move upward, so that the disc 808 squeezes the pillow 4, so that the pillow 4 can drive the rotating shaft 3 to rotate, and then the height of the pillow 4 can be adjusted, so that the pillow 4 can be suitable for patients in different conditions. When the pillow 4 is adjusted to a suitable height, the motor 804 is turned off, and then the height of the baffle 802 is adjusted, so that the baffle 802 can keep the patient's ankle joint at ninety degrees. At this time, it is necessary to start the two electric push rods 801 at the same time, so that the two electric push rods 801 drive the baffle 802 to move upward at the same time. When the baffle 802 moves to a suitable position, the two electric push rods 801 are turned off, and then the height adjustment of the pillow 4 and the baffle 802 is completed.
