Abstract

This utility model discloses an adjustable resistance grip ball for cardiac function training, relating to the field of rehabilitation training technology. The utility model includes a grip ball with a fixed tube fixedly connected to its outer wall, and a connecting hose fixedly connected to the outer wall of the fixed tube. The utility model incorporates a piston that, during its displacement, drives a damping rod to move. The damping rod, during this displacement, compresses a spring, which in turn applies resistance to the indirectly received gripping force. Training is performed by continuously squeezing the grip ball. To adjust the resistance, a knob is rotated, causing a threaded rod to rotate. This threaded rod then moves a fixed frame, which in turn moves a damping sleeve. The damping sleeve then moves one end of the spring to stretch it, reducing the resistance it provides. This allows for free adjustment of the resistance provided during training, enabling patients to perform rehabilitation training according to their own cardiac function level, thereby improving the heart's workload capacity.

Description

Technical Field

[0001] This utility model belongs to the field of rehabilitation training technology, and in particular relates to an adjustable resistance grip ball for cardiac function training. Background Technology

[0002] Cardiology, also known as cardiology or cardiac surgery, is a medical discipline that specializes in the study of heart or vascular diseases. Both cardiology and cardiac surgery treat diseases caused by the cardiovascular system or heart. Cardiology mainly uses drug therapy, but also includes interventional cardiology and non-invasive or minimally invasive surgeries such as coronary artery catheterization.

[0003] Cardiac function training is an effective intervention that includes rehabilitation assessment, exercise training, diet and behavior, thereby improving the function and structure of heart disease patients. Grip balls are a good training tool.

[0004] Existing equipment generally provides training at a fixed intensity, while most patients have varying training intensity requirements. This makes it difficult for patients to conduct rehabilitation training based on their own cardiac function level, which may prevent them from effectively improving their heart's load capacity. Therefore, we propose an adjustable resistance grip ball for cardiac function training. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable resistance grip ball for cardiac function training. Through the adjustment mechanism and the anti-dislodgement mechanism, it solves the problem that the intensity of most training that can be performed is fixed, while the training intensity requirements of most patients are not fixed. This makes it inconvenient for patients to carry out rehabilitation training according to their own cardiac function level, which may lead to the problem that patients cannot effectively improve their heart's load capacity.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a resistance adjustable grip ball for cardiac function training, including a grip ball, a fixed tube fixedly connected to the outer wall of the grip ball, a connecting hose fixedly connected to the outer wall of the fixed tube, and an adjustment mechanism provided on the outer wall of the connecting hose away from the grip ball.

[0008] The adjusting mechanism includes a transition cylinder, the outer wall of which is fixedly connected to the outer wall of a connecting hose, a base fixedly connected to the inner wall of the transition cylinder, a connecting pipe fixedly connected to the outer wall of the transition cylinder, a piston tube fixedly connected to the outer wall of the connecting pipe, the bottom outer wall of the piston tube fixedly connected to the top outer wall of the base, a piston groove formed on the inner wall of the piston tube, a piston slidably connected to the inner wall of the piston groove, a damping sleeve slidably connected to the inner wall of the piston groove, a damping groove formed on the inner wall of the damping sleeve, a damping rod slidably connected to the inner wall of the damping groove, and a spring fixedly connected to the outer wall of the damping groove.

[0009] Furthermore, the outer wall of the end of the spring away from the damping groove is fixedly connected to the outer wall of the damping rod, and a threaded rod seat is fixedly connected to the top outer wall of the base, and a threaded rod is rotatably connected to the inner wall of the threaded rod seat.

[0010] Furthermore, a knob is fixedly connected to the top outer wall of the threaded rod, a fixed frame is drivenly connected to the outer wall of the threaded rod, the inner wall of the fixed frame is fixedly connected to the outer wall of the damping sleeve, a plurality of fixed rods are slidably connected to the inner wall of the fixed frame, and the bottom outer walls of the plurality of fixed rods are fixedly connected to the top outer wall of the base.

[0011] Furthermore, the outer wall of the fixing tube is provided with an anti-detachment mechanism, which includes a connecting rope, a fixing block is fixedly connected to the outer wall of the connecting rope, and a collar is fixedly connected to the outer wall of the fixing block.

[0012] Furthermore, a bearing seat is fixedly connected to the outer wall of the collar, a rotating shaft is rotatably connected to the inner wall of the bearing seat, and a second collar is fixedly connected to the outer wall of the rotating shaft.

[0013] Furthermore, a locking sleeve is fixedly connected to the outer wall of the second collar, and a slot is provided on the inner wall of the locking sleeve, with a pin slidably connected to the inner wall of the slot.

[0014] Furthermore, the inner wall of the pin is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to a limiting block, the outer wall of the limiting block being fixedly connected to the outer wall of the collar.

[0015] Furthermore, the inner wall of the pin is provided with a plurality of snap-fit ​​grooves, and the inner walls of the plurality of snap-fit ​​grooves are slidably connected with snaps. The outer wall of the snaps is fixedly connected with a second spring, and the outer wall of the second spring is fixedly connected to the inner wall of the snap-fit ​​groove.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model incorporates a piston. Air propels the piston upward, which in turn moves a damping rod. This rod compresses a spring, which in turn resists the gripping force. Training is achieved by repeatedly squeezing the grip ball. To adjust the resistance, a knob is turned. The knob rotates a threaded rod, which in turn moves a fixed frame. The fixed frame then moves a damping sleeve, which in turn moves one end of the spring to stretch it and reduce the resistance. This allows for free adjustment of the resistance provided during training, enabling patients to perform rehabilitation training according to their own cardiac function level, thereby improving the heart's workload capacity.

[0018] 2. This utility model incorporates a collar. Before training, several buckles can be pinched together, causing them to move closer together to prevent them from jamming the pin. The pin can then disengage from the slot, allowing the collar and the ring to move freely using the shaft and pivot. When the user's hand is placed between the collar and the ring, and the pin is inserted back into the slot, the buckles automatically reset under the action of the spring, preventing the collar and the ring from rotating. This effectively secures the grip ball near the patient's wrist, preventing it from slipping out of the patient's hand and falling during training.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] One specific application of this embodiment is:

[0036] When the device is needed, the patient can directly grasp the grip ball 1 and apply gripping force to compress the air inside. The air inside the grip ball 1 will first pass through the fixed tube 101 and the connecting hose 102 into the transition tube 201, and then through the transition tube 201 and the base 202 into the piston tube 204.
