Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a shoulder and neck function training aid for patients with cardiac pacemakers. Background Technology

[0002] Pacemaker implantation is an important treatment for some heart diseases. After the surgery, patients often need to perform shoulder and neck function training to prevent problems such as shoulder and neck muscle atrophy and joint stiffness caused by long-term restriction of activity.

[0003] The shoulder and neck function training aid for pacemaker patients aims to provide safe and effective support for shoulder and neck function training after pacemaker implantation, helping patients regain shoulder and neck mobility while ensuring that it does not affect the normal operation of the pacemaker. However, existing shoulder and neck function training aids for pacemaker patients have the following problems in use, mainly including: 1. Lack of specificity: Ordinary shoulder and neck training equipment does not take into account the special circumstances of patients with cardiac pacemakers. Cardiac pacemakers are sensitive to electromagnetic interference, and some conventional training equipment may generate electromagnetic effects, threatening the normal operation of the patient's cardiac pacemaker and thus endangering the patient's life. 2. Difficulty in controlling training intensity and method: During training, patients find it difficult to accurately control the training intensity and method on their own. Excessive training intensity may affect the stability of the pacemaker and even cause pacemaker displacement; insufficient training intensity will not achieve the goal of effectively exercising shoulder and neck function. Currently, there is a lack of an assistive device that can accurately adjust the training intensity and method according to the specific situation of the patient. 3. Poor comfort and adaptability: Existing assistive training equipment does not fully consider patient comfort and individual differences in its design. Different patients have different body shapes and shoulder and neck physiological structures, and universal equipment may not fit the patient's body well, resulting in discomfort during training, affecting training effectiveness and patient motivation.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Reference Figures 1-6 A neck and shoulder function training aid for pacemaker patients includes a base 1. A support frame 2 is fixedly connected to the upper surface of the base 1. A reinforcing rib 5 is fixedly connected to one side of the support frame 2. The lower surface of the reinforcing rib 5 is fixedly connected to the base 1. An adjusting cylinder 4 is fixedly connected to the upper surface of the base 1. A seat 3 is fixedly connected to the telescopic end of the adjusting cylinder 4. A limiting mechanism for limiting the movement of the seat 3 is provided on the side of the support frame 2 near the seat 3. A backrest 9 is fixedly connected to the upper surface of the seat 3. Two symmetrically arranged propulsion airbags 10 are provided on the front end of the backrest 9. A contact cover 13 is provided on one side of the support frame 2. A horizontal rib 14 and a vertical rib 15 are fixedly connected to the side of the support frame 2. A mounting plate 16 is fixedly connected to the side of the contact cover 13 near the support frame 2. A rotating frame 17 is rotatably connected to the side of the mounting plate 16 away from the contact cover 13. A connecting frame 18 is fixedly connected to the side of the rotating frame 17 away from the mounting plate 16. A support mechanism for supporting the contact cover 13 is provided on the side of the connecting frame 18 near the support frame 2. An air intake mechanism for supplying air to the propulsion airbag 10 is provided on one side of the support frame 2. Handrails 34 are provided on both sides of the backrest 9. A traction mechanism for rotating and pulling the handrails 34 is provided on both sides of the support frame 2.

[0018] The adjusting cylinder 4 uses a gas spring for easy control of its raising and lowering. The seat 3, backrest 9, and contact cover 13 all use silicone material as a partition to improve comfort. The main structure of the contact cover 13 is made of TPE thermoplastic rubber, providing elasticity and allowing for adjustment to different patients, improving the fit between the contact cover 13 and the patient's neck. The transverse ribs 14 and longitudinal ribs 15 are both made of TPU thermoplastic polyurethane, which has good toughness and deformation elasticity, providing contact support for the contact cover 13 during deformation. Figure 3 As shown, the mounting plate 16 and the contact cover 13 are in partial contact, which provides space for the deformation of the contact cover 13.

[0019] In the aforementioned cardiac pacemaker patient shoulder and neck function training aid, the limiting mechanism includes two symmetrically arranged limiting grooves 7 opened on the side of the support frame 2 near the seat 3. Two symmetrically arranged sliding frames 6 are slidably connected to the side of the support frame 2 near the seat 3. The sliding frames 6 are fixedly connected to the backrest 9. The side of the sliding frames 6 near the support frame 2 is fixedly connected to a limiting block 8. The limiting block 8 is slidably connected in the limiting groove 7.

[0020] The sliding frame 6 and the backrest 9 are an integrated structure, which can provide limits for the seat 3 and the backrest 9 during the up and down movement adjustment.

[0021] In the above-mentioned cardiac pacemaker patient shoulder and neck function training aid, the support mechanism includes two longitudinal frames 19 and a transverse frame 20 rotatably connected to the side of the connecting frame 18 away from the rotating frame 17. Both sides of the support frame 2 are fixedly connected to fixed frames 24. A sliding rod 23 is provided through the two fixed frames 24. A sliding sleeve 21 is slidably sleeved on the side wall of the sliding rod 23. The end of the transverse frame 20 away from the connecting frame 18 is rotatably connected to the sliding sleeve 21.

[0022] During processing, the surface of the sliding rod 23 is brushed to ensure a smooth surface.

[0023] In the above-mentioned cardiac pacemaker patient shoulder and neck function training aid, the opposite ends of the two sliding sleeves 21 are fixedly connected with retaining rings 25, and a constraint spring 22 is provided between the two retaining rings 25. The constraint spring 22 is sleeved on the side wall of the sliding rod 23.

[0024] The constraint spring 22 and the subsequent reset spring 27 are made of non-magnetic metal materials, such as titanium alloys. This avoids the electromagnetic induction phenomenon caused by conventional magnetic metal springs during frequent compression and traction, which could lead to electromagnetic interference in pacemaker use for patients with cardiac pacemakers.

[0025] In the aforementioned cardiac pacemaker patient shoulder and neck function training aid, a propulsion frame 26 is rotatably connected to the end of the longitudinal frame 19 away from the connecting frame 18. A guide frame 11 is fixedly connected to the side of the support frame 2 near the connecting frame 18. Two symmetrically arranged guide rods 12 are fixedly connected to one side of the guide frame 11. The propulsion frame 26 is slidably connected to the two guide rods 12. A return spring 27 is elastically connected between the upper propulsion frame 26 and the guide frame 11. The return spring 27 is sleeved on the side wall of the guide rod 12.

[0026] The guide rod 12 has a brushed surface to ensure a smooth surface.

[0027] In the aforementioned cardiac pacemaker patient shoulder and neck function training aid, the air intake mechanism includes a pressure frame 28 fixedly connected to the lower end face of the lower push frame 26, a compression airbag 29 is provided on one side of the guide frame 11, the compression airbag 29 is sleeved on the side wall of the two guide rods 12, and the compression airbag 29 is connected to the push airbag through the delivery hose.

[0028] The delivery hose is made of conventional rubber hose. Both ends of the hose are locked and fixed with metal clamps at the connection points with the compression airbag 29 and the propulsion airbag 10 to maintain the airtightness of the connection points. The amount of air in the compression airbag 29 and the propulsion airbag 10 is set according to the range of motion of the user's back during movement.

[0029] In the aforementioned assistive device for training shoulder and neck function in patients with cardiac pacemakers, the traction mechanism includes a rotating groove 31 on one side of the lower pressure frame 28, a gear 32 rotatably connected in the rotating groove 31, a swing frame 33 fixedly connected to one side of the gear 32, a handrail 34 fixedly connected to the swing frame 33, and two symmetrically arranged toothed plates 30 fixedly connected to the lower end face of the lower pressure frame 28. The lower end face of the toothed plates 30 is slidably connected to the guide frame 11, and the toothed plates 30 mesh with the gear 32.

[0030] The toothed plate 30 has a sliding guide frame 11 running through its bottom, which provides a sliding limit for the movement of the toothed plate 30. In the initial state, the toothed plate 30 and the gear 32 are in a meshing state. When the maximum rotation angle of the handrail 34 is reached, the toothed plate 30 and the gear 32 are still in a meshing state. At the same time, the length of the toothed plate 30 is controlled according to the rotation range of the handrail 34.

[0031] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0032] The specific operation steps of this invention are as follows: like Figure 1-6As shown, during use, the patient first sits on the seat 3. The extension length of the cylinder 4 is adjusted according to the patient's height, allowing the contact cover 13 to be positioned at the patient's neck. The patient sits on the seat 3 with their back against the backrest 9. The backrest 9 then contacts and compresses the propulsion airbag 10. Subsequently, the patient's neck contacts the contact cover 13. Supported by the contact of the transverse ribs 14 and longitudinal ribs 15, the contact cover 13 unfolds and conforms to the patient's neck. The patient then moves their neck backward (i.e., tilting their head back, causing their neck to move backward). At this time, the rotating frame 17 provides rotational support to the mounting plate 16, adjusting the rotation angle of the contact cover 13 to follow the patient's neck and head movements. The mounting plate 16, rotating frame 17 and connecting frame 18 are then moved. At this time, the two transverse frames 20 on the connecting frame 18 drive the sliding sleeves 21 at their ends to slide on the sliding rods 23. The constraint spring 22 between the two retaining rings 25 provides traction for the sliding sleeves 21, which provides traction for the patient during neck extension. The patient can control the force and angle of extension according to their own physical condition. At the same time, the two longitudinal frames 19 drive the push frame 26 to slide on the guide rods 12 on the guide frame 11. The upper reset spring 27 can be compressed during the movement and squeezing of the push frame 26 to store energy for the reset of the push frame 26. At the same time, it provides resistance for the patient during neck extension and provides a reverse thrust for the patient during neck reset, assisting the patient's reset process. like Figure 4 As shown, when the patient performs the aforementioned neck-tilting movement, the lower push frame 26 moves downwards, causing the lower pressure frame 28 below it to slide downwards. When the lower pressure frame 28 contacts the compression airbag 29, the air inside the compression airbag 29 is compressed and delivered to the push airbag 10 through the delivery hose. As the patient's neck continues to move backwards, the compression airbag 29 is compressed, continuously supplying air to the push airbag 10. At this point, the push airbag 10 contacts and abuts against the patient's back, thus moving the patient's upper torso forward. The range of motion follows... The patient's neck extension range is self-controlled. By repeating the process of head extension and repositioning, the patient can drive the forward push and repositioning of their upper torso, which can exercise the muscles of the head, neck, shoulders, and back. When the patient's neck is rotated and repositioned, the lower pressure frame 28 moves upward, releasing the pressure on the compression airbag 29. At this time, the patient's back can reposition itself after the forward push of the propulsion airbag 10 is released. At this time, the gas in the propulsion airbag 10 is transported back to the compression airbag 29 through the delivery hose, completing the air circulation between the propulsion airbag 10 and the compression airbag 29. During training, after sitting in seat 3, the patient places their arms on armrest 34. As the patient's neck moves backward, the downward pressure frame 28 moves downward. At this time, the toothed plate 30 below the downward pressure frame 28 slides at the bottom of the guide frame 11. The toothed plate 30 meshes with the gear 32. As the toothed plate 30 moves downward, it can drive the gear 32 to rotate. At this time, the swing frame 33 rotates with the gear 32 in the rotation groove 31, causing the armrest 34 on it to swing around the rotation center of the gear 32. This causes the patient's arms to swing and rise on the armrest 34. During the swinging of the patient's arms, the muscle groups in the shoulder, neck, and shoulder area are stretched and contracted, thereby achieving the effect of passive training of the patient's neck and shoulder muscles. Moreover, this movement process is controlled by the user's neck tilting motion, which achieves the effect of user self-control of training intensity, protection of the pacemaker and the patient.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
