Description

Technical Field

[0001] This utility model belongs to the field of rehabilitation equipment technology, specifically, it relates to an exercise device suitable for clinical use in cardiovascular medicine. Background Technology

[0002] With the development of cardiovascular rehabilitation technology, various clinical exercise devices have been widely used in the rehabilitation training of patients after surgery or during the recovery period of chronic diseases. These devices aim to enhance patients' cardiopulmonary function, improve blood circulation, and promote the recovery of limb muscle strength through scientific and controllable exercise. However, existing equipment still has many limitations in practical application, especially in terms of adapting to the bedside environment, ease of disassembly and use, and ability to coordinate upper and lower limb training.

[0003] For example, patent CN115518334B discloses a cardiovascular clinical exercise device. This device uses a worm gear transmission system to drive a human body support component to achieve multi-angle movement training and has a certain joint protection function, making it suitable for low-load exercise for post-cardiovascular surgery patients. However, this device has a complex structure and high integration, requiring fixed installation on a ground base, making it unsuitable for use in hospital beds. Furthermore, it lacks a detachable or portable design, making it difficult to deploy flexibly in the daily care of bedridden patients. In contrast, patent CN116035855B discloses another cardiovascular clinical exercise device. This device uses a drive component to link a support rod and a crossbar, enabling passive or active upper limb training under traction with a hanging ring, suitable for upper limb strength training for bedridden patients. However, the device is fixed in place during use and lacks modular and detachable design, making it impossible to move flexibly between different hospital beds. In addition, the device's training resistance adjustment relies on a mechanical reciprocating mechanism, which cannot achieve stepless adjustment or personalized setting of the exercise intensity. It is difficult to dynamically adjust the training intensity according to the patient's rehabilitation stage. Furthermore, the device only supports upper limb training and lacks support for lower limb or whole-body coordination exercises. Its single function makes it difficult to meet comprehensive rehabilitation needs.

[0004] Therefore, this utility model proposes an exercise device suitable for clinical cardiovascular medicine to solve the problems existing in the prior art. Utility Model Content

[0005] In view of this, the main purpose of this utility model is to provide an exercise device suitable for clinical cardiovascular medicine, so as to solve the problems of inflexible bed rest deployment, difficulty in dynamically adjusting training intensity according to the patient's rehabilitation stage, and inability to meet comprehensive rehabilitation needs of existing clinical exercise devices.

[0006] To achieve the above objectives, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An exercise device suitable for cardiovascular medicine clinical practice is detachably mounted on a bed board and includes a fixed frame. The fixed frame includes an integrally formed fixed support rod and a mounting crossbeam. The fixed support rod is symmetrically arranged at both ends of the mounting crossbeam. A through mounting groove is formed on the mounting crossbeam along its length, and a stretching exercise mechanism is arranged in the mounting groove. Furthermore, a prestress adjustment mechanism is also configured on the mounting crossbeam, and the prestress adjustment mechanism is matched with the stretching exercise mechanism.

[0008] The stretching exercise mechanism includes a connecting rope, which is a flexible rope. One end of the connecting rope is connected to a movable block that is movably disposed in the mounting groove, and the other end passes around a fixed pulley and is connected to a handle.

[0009] The prestress adjustment mechanism is a positioning column, which is movably inserted into the positioning hole on the mounting crossbeam and matches the movable block;

[0010] The mounting groove is provided with positioning pins and positioning holes evenly distributed on both sides of the edge, and the positioning pins and positioning holes are provided through the sliding groove.

[0011] In a preferred embodiment, the mounting crossarm is symmetrically provided with sliding grooves at both ends near the fixed support rod. The sliding grooves are perpendicular to and connected to the mounting grooves on the mounting crossarm. The movable block is movably disposed in the sliding groove, and a compression spring is also provided in the sliding groove. One end of the compression spring abuts against the inner wall of the sliding groove, and the other end matches the movable block.

[0012] In a preferred embodiment, the fixed pulley is mounted in the mounting groove by means of pins at both ends, and a guide groove is also provided on the fixed pulley to match the connecting rope.

[0013] In a preferred embodiment, the handle is a triangular structure located at the end of the connecting rope, and a through-hole is provided at the bottom of the adjacent inclined surface of the two handles, the through-hole matching the flexible connector.

[0014] In a preferred embodiment, the flexible connector includes limiting posts and bandages, with the limiting posts respectively disposed at both ends of the bandages and matching the through-hole positioning holes.

[0015] In a preferred embodiment, the through-hole is provided with a clearance portion in the middle, the width of which matches the diameter of the limiting post, and the opening width of the through-hole is smaller than the diameter of the limiting post.

[0016] In a preferred embodiment, the lower end of the fixed support rod is provided with a connecting foot plate, which is detachably connected to the bed board.

[0017] Compared with the prior art, this utility model provides an exercise device suitable for clinical cardiovascular medicine, which has the following beneficial effects:

[0018] 1. This exercise device features a detachable design. The mounting frame can be quickly installed or removed from the bed board via connecting footboards, adapting to the space requirements of hospital wards or rehabilitation areas. It is especially suitable for cardiovascular patients who need to frequently adjust their treatment environment due to their condition, thus improving the flexibility and adaptability of the equipment.

[0019] 2. The fixed support rod and the installation crossbeam are integrally molded, resulting in a stable structure. The sliding groove design allows for precise guidance of the moving blocks, ensuring the stability of movements during exercise and preventing training effects or secondary injuries caused by equipment shaking.

[0020] 3. The stretching exercise mechanism enables targeted training of multiple parts of the upper limbs, lower limbs, and calves: the triangular structure of the handles accommodates both hand grip and heel insertion, while the flexible connectors, through the locking design of the limiting posts and through-hole positioning holes, can quickly form a calf support ring to meet the training needs of the calf muscles. This "multi-purpose" design reduces the space occupied by the equipment while covering the training needs of different muscle groups in cardiovascular rehabilitation, thus improving rehabilitation efficiency.

[0021] 4. The prestress adjustment mechanism precisely controls the initial compression of the compression spring by adjusting the maximum displacement of the moving block, achieving stepless adjustment of the exercise resistance. Cardiovascular patients require personalized loads due to differences in their conditions; this design avoids risks caused by excessive load or ineffective training by too light load, conforming to the principle of "gradual progression and within one's capacity" in rehabilitation medicine. Simultaneously, the elastic resistance of the compression spring is linear, ensuring stable resistance during exercise and further guaranteeing training safety. This solves the problems of inflexible deployment in bed, difficulty in dynamically adjusting training intensity according to the patient's rehabilitation stage, and inability to meet comprehensive rehabilitation needs of existing clinical exercise devices.

[0033] The structure of this exercise device suitable for clinical cardiovascular medicine will be further described in detail below with reference to the accompanying drawings and embodiments of the present invention.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments as described in this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0036] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0037] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

[0038] The following is combined with Figures 1 to 7 This invention describes an exercise device suitable for clinical use in cardiovascular medicine.

[0039] An exercise device suitable for cardiovascular medicine clinical practice is detachably mounted on a bed board 1. It includes a fixing frame 2, which comprises an integrally formed fixing support rod 21 and a mounting crossbeam 22. The fixing support rod 21 is symmetrically arranged at both ends of the mounting crossbeam 22, and a connecting foot plate 26 is provided at the lower end of the fixing support rod 21. The connecting foot plate 26 enables a detachable connection to the bed board 1, ensuring stable installation. A through mounting groove 23 is formed along the length of the mounting crossbeam 22, within which a stretching exercise mechanism 3 is installed. During use, the stretching exercise mechanism 3 is used to exercise the patient's upper or lower limbs. Furthermore, a prestress adjustment mechanism 4 is also configured on the mounting crossbeam 22. The prestress adjustment mechanism 4 works in conjunction with the stretching exercise mechanism 3. By adjusting the prestress through the prestress adjustment mechanism 4, the exercise intensity can be individually adjusted to meet the clinical exercise needs of different patients.

[0040] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the limb exercise mechanism 3 includes a connecting rope 31, which is a flexible rope. One end of the connecting rope 31 is connected to a movable block 34 that is movably installed in the mounting groove 23, and the other end passes around a fixed pulley 32 and is connected to a handle 33, forming a limb exercise system. When the patient pulls the connecting rope 31 through the handle 33, the connecting rope 31 can drive the movable block 34 to move within the mounting groove 23, thereby training the patient's upper or lower limb strength.

[0041] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the mounting crossbeam 22 is symmetrically provided with sliding grooves 24 at both ends near the fixed support rod 21. The sliding grooves 24 are perpendicular to and connected to the mounting grooves 23 on the mounting crossbeam 22. The movable block 34 is movably installed in the sliding groove 24, and the sliding groove 24 guides the movement direction of the movable block 34. A compression spring 41 is also provided in the sliding groove 24. One end of the compression spring 41 abuts against the inner wall of the sliding groove 24, and the other end cooperates with the movable block 34. Therefore, when the movable block 34 moves along the sliding groove 24, it can compress the compression spring 41 to deform it. The elastic reaction force of the compression spring 41 provides an external force to resist deformation during the stretching process, thereby realizing the weight-bearing exercise function of the patient.

[0042] In the above description, during use, the patient moves the traction block 34 along the slide 24 to perform stretching movements of the upper or lower limbs. The compressed spring 41 generates resistance in the opposite direction of movement, forming an exercise load. At the same time, the prestress adjustment mechanism 4 set on the mounting crossbeam 22 can adjust the initial compression of the spring 41, thereby adjusting the magnitude of the exercise resistance in a personalized manner to meet the load intensity needs of patients at different rehabilitation stages and improve the pertinence and safety of the exercise.

[0043] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the fixed pulley 32 is installed in the mounting groove 23 by pins at both ends, and a guide groove 321 is also provided in the middle of the fixed pulley 32 to cooperate with the connecting rope 31 to guide the movement of the connecting rope 31.

[0044] In a preferred embodiment, such as Figure 1 and Figure 5As shown, the prestressing adjustment mechanism 4 is a positioning column 42. The positioning column 42 is movably inserted into the positioning column positioning hole 25 on the mounting crossbeam 22 and works in conjunction with the movable block 34 to limit the movement of the movable block 34. The positioning column positioning holes 25 are evenly distributed on both sides of the mounting groove 23 and penetrate through the sliding groove 24, so that after the positioning column 42 is inserted, it can be located on both sides of the movable block 34, directly limiting the range of movement of the movable block 34 within the sliding groove 24.

[0045] In the above description, during use, medical staff or patients can select different positions of the positioning pin positioning hole 25 to insert into the positioning pin 42 according to training needs. By adjusting the maximum displacement of the movable block 34, the initial compression degree of the compression spring 41 can be changed: when the positioning pin 42 is inserted into the positioning pin positioning hole 25 near the end of the slide groove 24, the allowable range of motion of the movable block 34 is reduced, and the compression spring 41 is pre-compressed more, requiring greater elastic resistance to be overcome during exercise; conversely, the resistance is reduced, thereby precisely adjusting the training load to meet the personalized exercise needs of patients at different rehabilitation stages.

[0046] In a preferred embodiment, such as Figure 1 , Figure 6 and Figure 7 As shown, the handle 33 is a triangular structure installed at the end of the connecting rope 31. This design combines hand gripping and foot insertion functions: the edges of the triangular handle are rounded, conforming to ergonomics, allowing patients to perform upper limb stretching exercises by gripping it; at the same time, its bottom structure can be adapted to the shape of the heel, and after the patient inserts their heel into the handle 33, they can use leg force to drive the movable block 34 to move along the slide groove 24, achieving targeted lower limb exercise needs.

[0047] In the above instructions, during use, the patient selects the operation method according to the training goal: for upper limb exercises, the hand grasps the handle 33 and pulls it outward, the connecting rope 31 pulls the movable block 34 to compress the compression spring 41, and the elastic resistance of the compression spring 41 achieves strength training; for lower limb exercises, the heel is inserted into the bottom of the handle 33, and the leg extension movement drives the movable block 34 to move, which also triggers the deformation resistance of the compression spring 41. Both operations adjust the initial compression amount through the prestress adjustment mechanism 4 of the compression spring 41, thereby personalized control of the exercise load to meet the needs of different rehabilitation stages.

[0048] Specifically, such as Figure 6 and Figure 7 As shown, in order to meet the needs of calf exercise, a through-hole positioning hole 331 is provided at the bottom of the adjacent inclined surface of the two handles 33. The through-hole positioning hole 331 is used in conjunction with the flexible connector 5. When performing calf exercise, by passing the flexible connector 5 through the through-hole positioning hole 331 of the two handles 33, the two can be connected to form a ring support structure, providing a place for the calf to rest.

[0049] In the above description, during use, the patient places their lower leg on the ring support formed by the flexible connector 5, and uses the force of their leg to drive the movable block 34 to move along the slide groove 24, compressing the compression spring 41 in the slide groove 24 to generate elastic resistance; at the same time, the prestress adjustment mechanism 4 changes the initial compression amount of the compression spring 41 by adjusting the position of the positioning column 42 in the positioning hole 25, thereby adjusting the size of the exercise load in a personalized way to meet the targeted strength training needs of the calf muscles at different rehabilitation stages.

[0050] Specifically, such as Figure 6 and Figure 7 As shown, the flexible connector 5 includes a limiting post 51 and a bandage 52. The limiting post 51 is respectively disposed at both ends of the bandage 52 and is used in conjunction with the through-hole positioning hole 331 on the handle 33. The through-hole positioning hole 331 has a relief portion in the middle, the width of which matches the diameter of the limiting post 51, while the opening width of the through-hole positioning hole 331 is smaller than the diameter of the limiting post 51. During installation, after the limiting post 51 is passed through the relief portion of the through-hole positioning hole 331, the limiting post 51 is locked and fixed because its diameter is larger than the opening width, thus achieving a stable connection between the flexible connector 5 and the handle 33.

[0051] In the above description, during use, the patient places their lower leg on the ring support formed by the bandage 52 connecting two handles 33. By exerting force with their leg, the patient moves the movable block 34 along the slide groove 24, compressing the spring 41 within the slide groove 24 to generate elastic resistance. Simultaneously, the prestress adjustment mechanism 4 changes the initial compression of the spring 41 by adjusting the position of the positioning post 42 in the positioning hole 25, thereby individually adjusting the amount of exercise load. This design ensures the reliable installation of the flexible connector 5 and prevents it from falling off during use through the limiting structure, meeting the targeted strength training needs of the calf muscles at different rehabilitation stages.

[0052] The operating principle and usage process of the exercise device applicable to cardiovascular medicine clinical practice described in this utility model include:

[0053] Usage process: First, the fixing frame 2 is detachably installed on the bed board 1 via the connecting foot plate 26 to ensure that the fixing support rod 21 provides symmetrical and stable support; then, adjust the prestress adjustment mechanism 4 according to the patient's rehabilitation needs, select the appropriate position of the positioning hole 25 on the mounting crossbeam 22 and insert the positioning column 42, and adjust the initial compression amount of the compression spring 41 to set the exercise load by limiting the range of motion of the movable block 34 in the slide groove 24. When performing upper limb exercises, the patient holds the handle 33 (triangular structure) and pulls the connecting rope 31 outward to move the movable block 34 along the slide groove 24, compressing the compression spring 41 to generate elastic resistance. When performing lower limb exercises, the patient inserts the heel into the recessed area at the bottom of the handle 33 and drives the movable block 34 to move through the leg extension action. If calf exercises are required, the limiting post 51 of the flexible connector 5 passes through the through-hole positioning hole 331 of the two handles 33 (the installation is completed using the middle relief part), and the bandage 52 forms a ring support to support the calf. The patient then drives the movable block 34 to move through the leg force, and the targeted strength training is achieved throughout the process through the deformation resistance of the compression spring 41.

[0054] Operating Principle: This device provides exercise resistance through the elastic deformation of the compression spring 41. Its core principle is as follows: when the movable block 34 is pulled within the slide groove 24, the compression spring 41 is compressed, generating an elastic reaction force opposite to the direction of movement. The patient must overcome this force to complete the stretching action, thereby achieving muscle strength training. The prestress adjustment mechanism 4, through the insertion of the positioning post 42 into the positioning hole 25 at different positions, changes the maximum allowable displacement of the movable block 34, thereby adjusting the initial compression degree of the compression spring 41—the closer the positioning post 42 is to the end of the slide groove 24, the greater the initial compression of the compression spring 41, and the stronger the resistance to be overcome during exercise; conversely, the resistance decreases, meeting the personalized load needs of patients at different rehabilitation stages. The triangular design of the handle 33 accommodates both hand gripping and foot insertion. The flexible connector 5, through the locking structure between the limiting post 51 and the through-hole positioning hole 331, ensures stable support for the lower leg during exercise, jointly achieving targeted exercise of multiple parts of the upper limbs, lower limbs, and lower legs.

[0055] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
