Description

Technical Field

[0001] The invention belongs to the field of clinical rehabilitation equipment, and in particular relates to a safety dumbbell suitable for clinical resistance exercise. Background Art

[0002] Resistance training, also known as resistance training, is a type of exercise that resists resistance. Its main purpose is to train the body's muscles. The only way to increase muscle weight and strength is strength training. Clinically, resistance exercise is also used in various diseases, such as cardiovascular disease, lung disease, and even digestive system diseases. Traditional resistance training equipment on the market currently includes dumbbells, barbells, elastic bands, etc. Among them, dumbbells and barbells are easy to use, but if they are accidentally dropped, they can easily injure patients, causing medical accidents and posing certain safety hazards; elastic bands are elastic and safer and more convenient for patients to use, but they are easy to entangle drainage tubes when exercising with elastic bands, so they cannot be popularized clinically. Invention content

[0003] In view of this, the invention aims to propose a safe dumbbell suitable for clinical resistance exercise, which can be used in clinical resistance training to avoid entanglement of the drainage tube and better prevent the patient from being injured when the dumbbell falls.

[0004] To achieve the above object, the technical solution created by the present invention is implemented as follows:

[0005] A safe dumbbell suitable for clinical resistance exercise comprises a dumbbell rod for hand grip, with spherical dumbbell heads arranged at both ends of the dumbbell rod, the dumbbell rod comprising an outer sheath and weight filling particles arranged inside the outer sheath, the outer sheath being made of a soft rubber material; the dumbbell head comprising an outer cover, an inner cover, and expanded polystyrene particles filled between the outer cover and the inner cover, the outer cover and the inner cover being made of a soft material.

[0006] Furthermore, the soft material is canvas, linen, suede, flocking or non-woven fabric.

[0007] Furthermore, a zipper is arranged on the outer surface of the jacket, and a zipper which can be opened and closed is arranged on the zipper.

[0008] Furthermore, the filling particles are made of iron or alloy materials.

[0009] Furthermore, a music player is arranged in the dumbbell head, and the music player includes a driving power supply, a speaker, a storage chip, a control circuit board and a switch button.

[0010] Furthermore, a motion detection device is arranged in the dumbbell bar, including a power supply, an acceleration sensor, a processor and a speaker. The acceleration sensor is used to detect the acceleration of the dumbbell during movement. The signal input end of the processor is connected to the acceleration sensor, and the signal output end of the processor is connected to the speaker.

[0011] Furthermore, the motion detection device also includes a three-axis gyroscope, which is used to detect the angular velocity of the three axes of X, Y, and Z, and the three-axis gyroscope is connected to the signal input terminal of the processor.

[0012] Compared with the prior art, the safe dumbbell suitable for clinical resistance exercise created by the present invention has the following advantages:

[0013] (1) The outer layer, outer sleeve, inner sleeve and expanded polystyrene particles created by the present invention make the dumbbell head deformable and the dumbbell rod bendable; the filling particles are wrapped by the outer layer, outer sleeve, inner sleeve and expanded polystyrene particles, and the filling particles and the expanded polystyrene particles are isolated from each other by the inner sleeve, so that the dumbbell as a whole and the filling particles inside it have the characteristic of being deformable, which is suitable for use in clinical resistance training. In particular, when patients with cardiovascular diseases, lung diseases and digestive system diseases need to use drainage tubes, the safety dumbbell created by the present invention can be used to change its shape according to the needs of the patients to avoid touching or entanglement with the drainage tubes; and the outer layer, outer sleeve, inner sleeve and expanded polystyrene particles form a safety buffer outside the filling particles, which better prevents the dumbbell from hitting the patient when it falls, thereby reducing the hidden dangers of medical accidents.

[0014] (2) In addition, the outer layer is made of a soft rubber material. After the filling particles inside are weighted, the dumbbell bar does not have rebound performance, thereby solving the problem in the prior art that the elastic band rebounds during exercise and is easily entangled in the drainage tube.

[0015] (3) The dumbbells described in the present invention are provided with an acceleration sensor and / or a three-axis gyroscope, and the acceleration sensor can monitor the movement of the dumbbells, thereby playing a counting role. When a lifting or lifting action is completed, the acceleration sensor converts the collected movement into an electrical signal, and the processor records the action accordingly and emits a counting sound through a speaker, so as to help patients and medical staff control the patient's training amount.
