Description

Technical Field

[0001] This utility model relates to the field of medical rehabilitation equipment technology, specifically a portable upper limb rehabilitation training device for frail patients. Background Technology

[0002] In postoperative rehabilitation and frailty in the elderly, upper limb rehabilitation training for patients with muscle weakness (such as those in the postoperative recovery period) is a crucial step in restoring daily living abilities (such as dressing, eating, and independent movement). The core need is not only to improve muscle strength but also to cover overall upper limb function, shoulder and neck coordination, and fine motor skills through diverse training methods to adapt to different rehabilitation stages from bedridden to home-based living. However, current upper limb rehabilitation training equipment on the market has significant shortcomings in the comprehensiveness of training methods and adaptability to different scenarios, making it difficult to meet the refined rehabilitation needs of frail patients.

[0003] From the perspective of training coverage, traditional upper limb rehabilitation devices generally suffer from the problem of "functional limitation": most devices only focus on overall upper limb strength training (such as simple pushing, pulling, and lifting movements), and can only exercise the basic muscle strength of the upper arm and forearm, but neglect the need for coordinated rehabilitation of the shoulder and neck area and training of fine motor skills of the fingers.

[0004] From the perspective of scenario adaptability, the "bulky" nature of traditional equipment further limits the implementation of diversified training. Most rehabilitation devices are larger than 1 square meter in size and weigh more than 10 kg, and can only be fixed in specific areas of rehabilitation institutions or hospitals, which cannot meet the needs of patients for home-based or community-based rehabilitation. Furthermore, rehabilitation for frail patients often requires long-term adherence and flexible adjustment of training methods according to the home environment (such as the dining table or bedside).

[0005] Therefore, a portable upper limb rehabilitation training device for frail patients is proposed. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a portable upper limb rehabilitation training device for frail patients, so as to solve the problems mentioned in the background technology.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0008] This utility model provides a portable upper limb rehabilitation training device for frail patients, including two symmetrically arranged support seats. Each of the two support seats has an inclined support rod fixedly on its top. The two support rods are distributed in a figure-eight shape, and the upper ends of the two support rods are fixedly provided with the same support plate. The upper surface of the support plate is symmetrically fixed with two screws, and the rod walls of the two screws are provided with nuts. The top of the support plate is fixedly provided with a training mechanism through the cooperation of the screws and nuts.

[0009] Preferably, the training mechanism includes a first tray inserted into the two screws, and the first tray is fixedly connected to the support plate by the cooperation of the screws and nuts. A support plate is fixedly provided on the top of the first tray, and handles are fixedly provided on both sides of the upper surface of the support plate.

[0010] Preferably, the training mechanism includes a second tray inserted into the two screws, and the second tray is fixedly connected to the support plate by the cooperation of the screws and nuts. A U-shaped slide rod is fixedly provided on the top of the second tray. Movable rings are sleeved on both sides of the U-shaped slide rod. Elastic bands are fixedly provided on the side walls of the two movable rings. Pulling rings are fixedly provided at the ends of the two elastic bands away from the movable rings.

[0011] Preferably, the training mechanism includes a third tray inserted into the two screws, and the third tray is fixedly connected to the support plate by the cooperation of the screws and nuts. A U-shaped socket is fixedly provided on the top of the third tray, and a plug plate is vertically inserted into the inside of the U-shaped socket.

[0012] Preferably, the surface of the plug-in plate has a plurality of evenly distributed plug-in holes.

[0013] Preferably, the bottom of each of the two support bases is fixed with a plurality of evenly distributed suction cups.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The first tray's handle supports lateral pushing and pulling movements as well as rowing motions, specifically targeting and training the overall strength and coordination of the upper limbs. The second tray's combination of elastic bands and U-shaped slides allows for flexible adjustment of the training angle, adapting to synergistic shoulder and neck training and relieving shoulder and neck stiffness. The third tray's plug-in plate and plug-in holes enable fine motor skills training for the fingers, helping patients with grade I muscle strength regain their ability to grasp, align, and perform other daily movements. This overcomes the limitations of traditional equipment with its single function, covering the full-dimensional rehabilitation needs of the upper limbs, shoulders, neck, and fingers.

[0017] Example 1 A portable upper limb rehabilitation training device for frail patients, such as Figure 1 and 4 As shown, the device includes two symmetrically arranged support bases 1. Multiple evenly distributed suction cups 18 are fixed to the bottom of each support base 1 to increase its stability. An inclined support rod 2 is fixed to the top of each support base 1, arranged in a V-shape. The upper ends of the two support rods 2 are fixed to the same support plate 3. Two screws 4 are symmetrically fixed to the upper surface of the support plate 3, and nuts 5 are provided on the walls of both screws 4. A training mechanism is fixed to the top of the support plate 3 through the cooperation of the screws 4 and nuts 5. Before use, the device is placed on a desktop or hospital bed table according to the training scenario. The multiple suction cups 18 at the bottom of the support base 1 adhere to the contact surface, ensuring stability and preventing displacement during training. If a change of training mode is required, the training mechanism can be quickly assembled and switched through the cooperation of the screws 4 and nuts 5. After training, the training mechanism is removed by unscrewing the nuts 5. The support base 1, support rod 2, and support plate 3 are made of aluminum alloy, making them easy to carry in homes, communities, and other scenarios, meeting diverse training needs.

[0018] The training mechanism includes a first tray 6 inserted into two screws 4, and the first tray 6 is fixedly connected to the support plate 3 through the cooperation of screws 4 and nuts 5. A support plate 7 is fixedly provided on the top of the first tray 6, and handles 8 are fixedly provided on both sides of the upper surface of the support plate 7. When the first tray 6 is selected as the training mechanism, the patient holds the handles 8 on both sides of the support plate 7 with both hands and performs training according to his / her own muscle strength: applying force in opposite directions with both hands can complete the opposite push and pull movement, exercise the muscle strength of the upper arm and forearm and the coordination of the limbs; pulling the support plate 7 forward or backward with both hands at the same time can simulate the rowing action, further strengthening the overall force exertion ability of the upper limbs and core stability. During the training process, the grip strength monitoring system in the preliminary idea can be combined with the pressure sensor built into the handle 8 to monitor the grip strength distribution in real time.

[0019] Example 2 like Figure 2 and 4As shown, the training mechanism includes a second tray 9 inserted into two screws 4, and the second tray 9 is fixedly connected to the support plate 3 through the cooperation of screws 4 and nuts 5. A U-shaped slide rod 10 is fixedly provided on the top of the second tray 9. Movable rings 11 are sleeved on both sides of the rod wall of the U-shaped slide rod 10. Elastic bands 12 are fixedly provided on the side walls of the two movable rings 11. Pulling rings 13 are fixedly provided at the ends of the two elastic bands 12 away from the movable rings 11. When the second tray 9 is used as the training mechanism, the patient holds the pulling rings 13 at the ends of the two elastic bands 12 with both hands. The position of the movable rings 11 on the U-shaped slide rod 10 is adjusted according to the needs of shoulder and neck movement to change the stretching angle of the elastic bands: pulling the elastic bands 12 to both sides can exercise the muscles of the shoulder and neck and relieve the stiffness of the shoulder and neck caused by long-term immobilization; pulling the elastic bands 12 up or down with both hands can specifically train the ability of the shoulder and neck to exert force, which is adapted to the needs of shoulder and neck rehabilitation. If weakness occurs suddenly during training, the pulling rings 13 can be released quickly to ensure safety.

[0020] Example 3 like Figure 3-4 As shown, the training mechanism includes a third tray 14 inserted into two screws 4, and the third tray 14 is fixedly connected to the support plate 3 through the cooperation of screws 4 and nuts 5. A U-shaped socket 15 is fixedly provided on the top of the third tray 14, and a plug plate 16 is vertically inserted into the inside of the U-shaped socket 15. The surface of the plug plate 16 has multiple evenly distributed plug holes 17. When assembling the third tray 14 as a training mechanism, the plug plate 16 is vertically inserted into the U-shaped socket 15. The patient uses their fingers to grasp the adapter plug. Based on the preliminary design idea, which is not clearly defined in document 1, it is usually a block / column structure that matches the plug hole 17. The patient aligns the plug plate 16 with the plug hole 17 on the surface of the plug plate 16 and inserts it to complete the action process of "grasping-aligning-inserting", thereby exercising finger flexibility and fine motor control ability.
