Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rehabilitation training, and particularly relates to a rehabilitation training system for spinal cord injury. BACKGROUND

[0002] Spinal cord injury is the most serious complication of spinal injury, often leading to severe dysfunction of the limbs below the injured segment. Spinal cord injury not only causes serious physical and psychological harm to the patient himself, but also causes huge economic burden to the whole society. Due to the social and economic losses caused by spinal cord injury, prevention, treatment and rehabilitation of spinal cord injury have become a major issue in the medical field. The rehabilitation auxiliary scheme for spinal cord injury mainly includes two steps: first, the recovery of basic physiological activity ability to ensure that the patient can meet his basic physiological needs, which mainly includes the transformation and maintenance among sitting, standing and walking postures; second, the recovery of certain body functions of the human body, especially the free transformation and maintenance among the sitting, standing and walking postures under the condition of bearing a certain degree of load.

[0003] For example, Chinese patent CN 115177865 A discloses a spinal cord electric stimulation system, which comprises an implanted stimulation electrode and an external power supply program controller. The implanted stimulation electrode is placed in the stimulated organism and comprises a stimulation end, a connecting part and a receiving end, all of which are made of materials that can be degraded and absorbed in the body or discharged out of the body. The receiving end receives the electric energy and stimulation signal of the external power supply program controller in a wireless manner, transmits the stimulation signal to the stimulation end through the connecting part, and the stimulation end is used for outputting the stimulation signal to stimulate the spinal cord nerve.

[0004] The spinal cord electric stimulation system provided by the application has no requirements on the patient's constitution, the external power supply program controller is convenient to wear, and is suitable for patients of any body type. However, the device of the application has the problems that in the process of wearing the external power supply program controller for rehabilitation training or charging, the program controller is fixed by a conventional waistband, and due to long-time wearing, it will cause pressure marks on the waist of the patient, and in severe cases, it will cause pressure sores, and the patient is not convenient to move and adjust, which will aggravate the pressure marks and pressure sores, and is not conducive to the effective rehabilitation training of the patient. Therefore, the present application provides a rehabilitation training system for spinal cord injury to solve the above problems. SUMMARY

[0005] The present application aims to provide a rehabilitation training system for spinal cord injury to solve the problem that in the process of wearing the external power supply program controller for rehabilitation training or charging, due to long-time wearing, it will cause pressure marks or pressure sores on the waist of the patient, which is not conducive to the effective rehabilitation training of the patient.

[0006] In order to achieve the above object, the basic scheme of the present application is as follows: a spinal cord injury rehabilitation training system, comprising a control module, an electric stimulation module, a communication module and a wireless charging module, the control module is signal connected with the electric stimulation module through the communication module, and the control module is electrically connected with the electric stimulation module through the wireless charging module;

[0007] The electric stimulation module comprises a pulse generator and an electrode array, the electrode array is implanted in the epidural cavity of the spinal cord cone between the lumbar region and the sacral region of the patient, the pulse transmitter is implanted in the patient's body, and a lead wire is connected between the pulse transmitter and the electrode array;

[0008] The control module comprises a waistband and a programmed instrument installed on the waistband, an inner layer is arranged on the inner side of the waistband, the inner layer contacts the skin of the waist of the patient, a sliding rail is installed on the outer side of the waistband, the programmed instrument is installed on the sliding rail at the upper and lower ends, and the programmed instrument is in sliding cooperation with the sliding rail;

[0009] A plurality of through holes in the shape of a Sierpinski triangle are arranged on the inner layer, channels are arranged between the plurality of through holes to communicate the through holes, the communication sequence is from large through holes to small through holes and from inner through holes to outer through holes, a plurality of spherical balls are placed in the largest through hole, the spherical balls are made of elastic material, the diameter of the spherical balls is larger than the diameter of the channel, and a gel is placed in the through hole.

[0010] The principle of the basic scheme is as follows: the spinal cord injury rehabilitation training system provided by the application is used for implanting an electrode array in an electric stimulation module into an epidural cavity on the dorsal side of a spinal cord cone between a lumbar vertebra area and a sacrum area of a patient, implanting a pulse emitter on an abdomen of the patient or a hip of the patient, connecting the pulse emitter and the electrode array through a wire, installing a program control instrument on a slide rail outside a waistband of the patient through a waistband, charging and transmitting signals to the pulse emitter implanted in the patient through a communication module and a wireless charging module on the program control instrument, enabling the electrode array to emit regular and accurate pulse electric stimulation after the pulse emitter receives the signals, stimulating muscle groups to be trained in a targeted manner, and combining dynamic movement of the patient to perform rehabilitation training of spinal cord injury; when the patient wears the waistband and performs rehabilitation training or charging, the position of the program control instrument can be adjusted by the program control instrument in sliding cooperation with the slide rail, and when the program control instrument is rotated, the skin of the waist of the patient is in contact with an inner layer of the waistband, a plurality of Schelbinsky triangle-shaped through holes arranged on the inner layer of the waistband are used for gradually approaching the area of the inner layer of the waistband in contact with the skin of the patient to zero and gradually approaching the area of the Schelbinsky triangle-shaped through holes to infinity, and a plurality of balls and gels placed in the through holes are used for rolling and mixing in the through holes of the inner layer of the waistband, and then the balls and gels are in contact with the skin of the patient, so that the balls and gels are used for reducing the compression of the waistband on the waist of the patient through the lubrication and protection effects of the gels; and the gels are used for flowing and filling from a large through hole to a small through hole and from an inner through hole to an outer through hole through the connected channels, so that the gels are uniformly applied to the skin of the waist of the patient to protect the skin of the waist of the patient.

[0011] The spinal cord injury rehabilitation training system provided by the application can use electric signals to enable the electrode array to perform electric stimulation on different positions of the spinal cord to recover from injury, generate corresponding muscle movement, and assist in completing rehabilitation training movement such as walking, so as to realize the function of assisting overall rehabilitation training.

The waistband in the control module in the spinal cord injury rehabilitation training system can effectively reduce the area of friction and compression of the waistband on the skin of the waist of the patient during long-term rehabilitation training, so as to reduce the pressure sores and marks caused by the waistband due to the shaking of the program control instrument on the waistband, and the shaking of the program control instrument on the slide rail can massage the waist of the patient to some extent, relieve the pressure on the waist of the patient, and increase the effect of spinal cord injury rehabilitation training.

[0012] Furthermore, the sphere is hollow inside, and its surface has several channels, with gel filling the interior.

[0013] The basic principle and beneficial effects of the solution are as follows: through the several channels on the surface of the sphere and the gel filling inside, when the patient moves and compresses the inner layer of the waist belt, the through-holes squeeze the sphere, squeezing out the gel inside the sphere. After the sphere's volume decreases, the sphere enters the small triangular through-holes around the circumference through the channels. Due to the reduced area of ​​the small triangular through-holes, the side walls squeeze the sphere again, allowing the gel inside the sphere to be fully squeezed out, thus increasing the gel's protective effect on the patient's waist skin.

[0014] Furthermore, the electrode array is made of magnesium-zinc alloy, and the surface of the electrode array is covered with an insulating layer.

[0015] The basic principle and benefits of the scheme are: the electrode array made of magnesium-zinc alloy and the surface wrapped with an insulating layer increase the stability and accuracy of electrical stimulation.

[0016] Furthermore, the conductor is made of magnesium-zinc alloy, and the surface of the conductor is wrapped with an insulating layer made of polyurethane.

[0017] The principle and beneficial effects of the basic scheme are: to increase the stability and security of electrical signal transmission through wires.

[0018] Furthermore, the programmable controller is equipped with buttons, a screen, and a charging port.

[0020] Furthermore, the wireless charging module includes a wireless charging transmitter installed on the programmable controller and a receiving coil installed inside the pulse transmitter.

[0021] The basic principle and beneficial effects of the solution are as follows: the power supply is transmitted to the receiving coil of the pulse transmitter implanted in the patient's body through the wireless charging transmitter installed on the programmable controller, so as to replenish the power of the pulse transmitter.

[0022] Furthermore, the pulse transmitter is implanted in the patient's abdomen or buttocks.

[0023] The basic principle and benefits of this solution are: to improve the safety of the pulse transmitter after it is implanted in the patient's body, and to facilitate wireless charging of the pulse transmitter.

[0024] Furthermore, the gel is a medical gel, and it contains an anti-pressure ulcer medication.
