Description

Technical Field

[0001] The utility model relates to the technical field of medical rehabilitation equipment, and in particular to a muscle strength precision training device based on muscle strength monitoring. Background Art

[0002] After injury to the musculoskeletal system, the local neuromuscular coordination ability will decline, and the injured muscles will not be able to actively contract and control joint movements according to the patient's wishes, which will lead to loss of function of the affected limb, or a decrease in the active contraction strength of a single muscle, which is mainly manifested as muscle weakness. For the above situations, effective means of rehabilitation treatment are local electrical stimulation, neuromuscular re-stimulation manual therapy and exercise training. Effective manual therapy includes muscle isometric contraction training and local muscle pressure induction training. Due to problems such as muscle inhibition and comprehension ability, patients cannot effectively master the movements and cannot effectively exercise the relevant muscles. Compensatory movements are prone to occur, which affects the rehabilitation effect and even the rehabilitation process. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-4 , the utility model provides a technical solution:

[0020] A muscle strength precision training device based on muscle strength monitoring includes a training strap 1, two ends of the training strap 1 are provided with a strap fixing assembly, the inner side of the training strap 1 is provided with a resistance applying airbag 4, the side of the resistance applying airbag 4 is connected to an trachea 6, an air pressure regulating assembly is installed on the trachea 6, the end of the trachea 6 is connected to a control box body 5, the bottom of the inner cavity of the control box body 5 is provided with a booster pump 9 connected to the trachea 6, the upper part of the inner cavity of the control box body 5 is connected to a micro control unit 8, the upper surface of the control box body 5 is installed with a touch screen 10, the side wall of the resistance applying airbag 4 is provided with a sensor mounting compartment 12, and a pressure sensor 11 is installed in the sensor mounting compartment 12.

[0021] The strap fixing assembly includes a second Velcro 3 provided at one end of the training strap 1, and a first Velcro 2 cooperating with the second Velcro 3 is provided at the other end of the training strap 1. The training strap 1 is fixed near the muscle attachment point of the quadriceps femoris of the patient's leg through the second Velcro 3 and the first Velcro 2.

[0022] The air pressure regulating assembly includes a first solenoid valve 7 and an exhaust pipe 13 provided on the air pipe 6. A second solenoid valve 14 is installed on the exhaust pipe 13. The booster pump 9 cooperates with the second solenoid valve 14 to apply resistance to the airbag 4 and fill it with gas.

[0023] The exhaust pipe 13 is located between the first solenoid valve 7 and the resistance applying airbag 4 .

[0024] The first solenoid valve 7 is a one-way valve, and the second solenoid valve 14 is an air release valve. The resistance-applying airbag 4 is exhausted through the second solenoid valve 14 and the exhaust pipe 13 to reduce the resistance of the resistance-applying airbag 4 to the patient's muscles.

[0025] The training strap 1 is fixed to the patient's leg near the muscle attachment point of the quadriceps femoris through the first Velcro 2 and the second Velcro 3. The patient contracts the quadriceps femoris, the pressure sensor 11 senses the muscle strength of the quadriceps femoris, and the touch screen 10 displays the data. According to the detected muscle strength, the booster pump 9 controls the resistance application airbag 4 to apply a certain resistance to the quadriceps femoris (a variety of modes can be designed, such as dynamic increase mode, or maximum resistance mode, etc.). The quadriceps femoris is stimulated by the resistance, inducing the patient to accurately contract the quadriceps femoris, avoiding compensatory contraction of other muscles and affecting the rehabilitation effect. Based on this idea, a training device for activating the major muscles of the limbs can be designed and developed.

[0026] The device is simple to learn and operate, and patients can complete the training on their own without the need for a therapist to accompany them throughout the process, saving labor costs. At the same time, the device has a high safety factor, and there is no need to worry about the training causing adverse effects or other damage to the surgical site.

[0027] This device collects muscle strength through the pressure sensor 11, senses muscle contraction, and then actively applies resistance to the relevant muscles, stimulating the patient to accurately contract the relevant muscles. Furthermore, based on the muscle strength of the patient's active muscle contraction collected by the pressure sensor 11, the microcontroller unit 8 and the booster pump 9 can cooperate with the first solenoid valve 7 and the second solenoid valve 14 to actively adjust the resistance of the second solenoid valve 14, applying corresponding pressure to the muscles. This dynamic pressure on the muscles can increase the efficiency of stimulating muscle fiber recruitment, quickly restore neuromuscular coordination and control capabilities, promote muscle strength recovery, strengthen the role of the muscle pump, improve limb blood circulation, and also have the effect of reducing swelling and relieving pain, accelerating patient recovery.

[0028] The first solenoid valve 7, micro control unit 8, boost pump 9, touch screen 10, pressure sensor 11 and second solenoid valve 14 all adopt common models on the market. The electrical connection relationship between the second solenoid valve 14 and the first solenoid valve 7, boost pump 9, touch screen 10, pressure sensor 11 and second solenoid valve 14 is a commonly used technical means in the existing technology.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
