Description

Technical Field

[0001] The utility model relates to the field of medical rehabilitation equipment, in particular to an auxiliary limb exercise device for critical care nursing. Background Art

[0002] Severely ill patients who stay in bed for a long time are prone to muscle weakness and limb movement disorders. Staff usually need limb exercise devices to help patients exercise to restore their limbs to normal state faster. Since long-term exercise with the same force will cause muscle numbness, the existing auxiliary limb exercise devices are not convenient for patients to change the force used each time when exercising the patient's limbs, thereby reducing the auxiliary effect of the patient's limb exercise. In addition, the existing auxiliary limb exercise devices are not convenient for correcting the movement trajectory of the patient's limbs, which leads to insufficient exercise of the patient's limbs, thereby reducing the efficiency of the patient's limb exercise. Utility Model Content

[0003] In order to overcome the above shortcomings, the utility model provides an auxiliary limb exercise device for critical care nursing, which can change the force used by the patient each time, thereby improving the auxiliary effect of the patient's limb exercise, and can fully exercise the patient's limbs, thereby improving the efficiency of the patient's limb exercise.

[0004] The technical solution is: an auxiliary limb exercise device for critical care nursing, including a support plate, wherein the support plate is fixedly connected with two sliding shafts, the two sliding shafts are symmetrically arranged, and blocks are fixedly connected to the two sliding shafts, and a limiting plate is fixedly connected between one end of the two sliding shafts away from the support plate, a hand rod is slidably connected between the two sliding shafts on the side close to the support plate, and a threaded slider is slidably connected between the two sliding shafts on the side close to the limit plate, a tension spring is connected between the threaded slider and the hand rod, a force amplifying component is provided on the limit plate, the force amplifying component is connected to the hand rod, and a correction component is provided on the support plate, each time the patient pulls the hand rod, the force amplifying component will stretch the tension spring for a distance, so that the patient needs to use greater force to pull the hand rod each time, thereby improving the auxiliary effect of the patient's limb exercise, and at the same time, the correction component will correct the movement trajectory of the patient's limbs, thereby more fully assisting the patient's limb exercise, thereby improving the efficiency of the patient's limb exercise.

[0005] As a further preferred solution, grooves are provided on both sides of the hand lever.

[0006] As a further preferred scheme, the force-enhancing component includes a rotating screw, which is rotatably connected to the limit plate, and the rotating screw is connected to the threaded slider through a thread, and the end of the rotating screw close to the hand rod is fixedly connected to a fixed sleeve, and the side of the fixed sleeve away from the rotating screw is fixedly connected to an overrunning clutch, the inner wall of the overrunning clutch is fixedly connected to a limiting bead, the hand rod is fixedly connected to a round shaft, the round shaft is provided with a sliding groove, and the limiting bead is slidably connected to the sliding groove on the round shaft.

[0007] As a further preferred embodiment, the correction assembly includes a limit block, wherein the two limit blocks are respectively fixedly connected to the two sides of the support plate, the two limit blocks are rotatably connected to a rotating rod, a torsion spring is connected between the rotating rod and the limit block, and the two rotating rods are connected to a strap.

[0008] As a further preferred solution, the binding strap has a heating function.

[0009] The utility model has the following advantages: 1. The patient pulls the hand lever to move in the direction of the support plate, and then the patient relaxes his muscles. The reset of the tension spring will drive the patient's arm to reset through the hand lever, and this is repeated, thereby assisting the patient's limb exercise. The reset of the hand lever will drive the round shaft to contact the limiting bead first, and then the round shaft continues to move, so that the slide groove of the round shaft squeezes the limiting bead to rotate in the opposite direction for one circle. The limiting bead rotates in the opposite direction for one circle, which will cause the rotating screw to rotate one circle through the overrunning clutch. The rotating screw rotates one circle, which will drive the limiting plate to move a certain distance, thereby stretching the tension spring for a certain distance, and this is repeated. Each time the patient pulls the hand lever, the tension spring will be stretched for a certain distance, so that the patient needs to use greater force to pull the hand lever each time, thereby improving the auxiliary effect on the patient's limb exercise.

[0010] 2. When the patient's two hands hold the two sides of the hand bar respectively, the arms will be straightened, and then the upper arms will rotate the rotating rod towards each other through the bandage, and the torsion spring will be twisted. Then when the patient pulls the hand bar, the rotating rod and the bandage drive the patient's upper arms to open outward under the action of the torsion spring, thereby correcting the movement trajectory of the patient's limbs, and then more fully assisting the patient's limb exercise, thereby improving the efficiency of the patient's limb exercise. When the bandage is electrified, it will generate heat around the patient's muscles, thereby alleviating the soreness of the patient's muscles caused by exercise, thereby improving the overall efficiency of the patient's limb exercise.

DETAILED DESCRIPTION

[0018] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0019] Embodiment 1: A limb training device for critical care, such as Figure 1-Figure 6 As shown, it includes a support plate 1, two sliding shafts 2 are welded on the support plate 1, the two sliding shafts 2 are symmetrically arranged, and blocks 3 are welded on the two sliding shafts 2. A limiting plate 4 is welded between the ends of the two sliding shafts 2 away from the support plate 1, and a hand bar 5 is slidably connected between the two sliding shafts 2 on the side close to the support plate 1. The hand bar 5 is used to exercise the patient's arm, and a threaded slider 6 is slidably connected between the two sliding shafts 2 on the side close to the limiting plate 4. The threaded slider 6 is connected to the hand bar 5 through a hook. A tension spring 7, a force-enhancing component is provided on the limit plate 4, and the force-enhancing component is connected to the hand rod 5. A correction component is provided on the support plate 1. Each time the patient pulls the hand rod 5, the force-enhancing component will stretch the tension spring 7 for a certain distance, so that the patient needs to use a greater force to pull the hand rod 5 each time, thereby improving the auxiliary effect on the patient's limb exercise. At the same time, the correction component will correct the movement trajectory of the patient's limbs, thereby more fully assisting the patient's limb exercise, thereby improving the efficiency of the patient's limb exercise.

[0020] The hand lever 5 has grooves on both sides.

[0021] The force-increasing component includes a rotating screw 8, which is rotatably connected to the limit plate 4, and is connected to the threaded slider 6 by threads. A fixing sleeve 9 is welded to the end of the rotating screw 8 close to the hand lever 5, and an overrunning clutch 10 is bolted to the side of the fixing sleeve 9 away from the rotating screw 8. The inner wall of the overrunning clutch 10 is bolted to a limiting bead 11, and a round shaft 12 is welded to the hand lever 5, and a sliding groove is opened on the round shaft 12. The limiting bead 11 is slidably connected to the sliding groove on the round shaft 12.

[0022] The correction component includes a limit block 13, and the two limit blocks 13 are respectively welded on both sides of the support plate 1. The two limit blocks 13 are rotatably connected to a rotating rod 14, and a torsion spring 15 is connected between the rotating rod 14 and the limit block 13. The two rotating rods 14 are connected to a strap 16, and the strap 16 is used to strap the patient's arm.

[0023] The binding belt 16 has a heating function.

[0024] First, the staff puts the support plate 1 against the patient's chest, and at the same time, ties two straps 16 to the patient's two upper arms, and energizes the straps 16. Then, the patient's two hands hold the two sides of the hand rod 5 respectively, and at the same time, the patient pulls the hand rod 5 to move toward the support plate 1, the tension spring 7 is stretched, and then the patient relaxes the muscles, the tension spring 7 resets, and the hand rod 5 drives the patient's arm to reset, and this is repeated, thereby assisting the patient's limb exercise. At the same time, the movement of the hand rod 5 toward the support plate 1 drives the round shaft 12 to move. Then, the slide groove of the round shaft 12 squeezes the limit bead 11 to rotate one circle. Under the action of the overrunning clutch 10, the rotating screw 8 will not be driven to rotate. The reset of the hand lever 5 will drive the round shaft 12 to reset. The reset of the round shaft 12 will first contact the limit bead 11, and then the round shaft 12 continues to move, so that the slide groove of the round shaft 12 squeezes the limit bead 11 to rotate one circle in the opposite direction. The limit bead 11 rotates one circle in the opposite direction, which will drive the fixed sleeve 9 to rotate one circle through the overrunning clutch 10. The fixed sleeve 9 rotates one circle, which will drive the rotating screw 8 to rotate one circle. The rotating screw 8 rotates one circle, which will drive the limit When the patient pulls the hand lever 5, the tension spring 7 is stretched for a certain distance, and this is repeated. Each time the patient pulls the hand lever 5, the tension spring 7 is stretched for a certain distance, and each time the patient needs to use a greater force to pull the hand lever 5, thereby improving the auxiliary effect on the patient's limb exercise. When the patient's two hands hold the two sides of the hand lever 5 respectively, the arms will be straightened, and then the upper arms will rotate in the direction of approaching each other through the bandage, and the torsion spring 15 will be twisted. Subsequently, when the patient pulls the hand lever 5, the rotating rod and the strap 16 drive the patient's upper arms to open outward under the action of the torsion spring 15, thereby correcting the movement trajectory of the patient's limbs, thereby more fully assisting the patient's limb exercise, thereby improving the efficiency of the patient's limb exercise, and the strap 16 will generate heat around the patient's muscles when it is energized, thereby relieving the soreness of the patient's muscles caused by the exercise, thereby improving the overall efficiency of the patient's limb exercise. After the exercise, the staff asks the patient to let go of his hands, and then the staff turns off the power to the strap 16 and removes the strap 16 from the patient's arm.
