Description

Rehabilitation training ball

Technical Field

The invention belongs to the field of health care and rehabilitation equipment, in particular to a rehabilitation training ball which is mainly applied to rehabilitation training of the motor function and the nervous system function of the upper limb of a human body.

Background

For postoperative rehabilitation training of accident disabled people, the rehabilitation training is helpful for patients to keep better limb functions, so that basic life self-care is realized, and life confidence is remodeled in the rehabilitation process. For old limb function degeneration patients caused by physical and brain function degeneration, the rehabilitation training can be carried out as early as possible, which is helpful for delaying function degeneration and even recovering to normal state. The use of rehabilitation sports equipment is a main means of rehabilitation training. In the existing rehabilitation exercise equipment, various exercise mechanisms are designed through various mechanical designs, and a patient is exercised in exercise by increasing exercise resistance, so that the purpose of rehabilitation training is achieved. However, the mechanical structure cannot meet the requirement of the movement of the joints of the human body because the joints and the muscle groups of the human body are quite complex and exquisite. The existing training apparatus can only be used for training the movement of a single joint, muscle group and nerve plexus. The rehabilitation requirements of patients cannot be met. Most of the rehabilitation exercises are boring, monotonous and repeated mechanical actions, and the rehabilitation exercises are not interesting, so that the enthusiasm of patients on the rehabilitation exercises cannot be stimulated. Can motivate people to have enthusiasm for rehabilitation training, and is especially important for patients with lower intelligence such as senile diseases, brain injury, cerebral palsy and the like. Chinese patent document CN101063907a discloses a "a mastering mouse and method of use" in 2007, 10 and 31, the mouse comprising a trackball and a base, and two parts on the base: the device comprises a track ball supporting and resetting mechanism, a track ball rotary motion detecting mechanism and a track ball position movement detecting mechanism. The motion detection parts of the mouse are electrically connected with each other and the host. The application method comprises the following steps: the operator pushes the track ball to rotate, so that the cursor correspondingly moves on the screen; pressing the track ball by the palm of the operator to enable the track ball to move, which is equal to clicking the left key or the right key of the mouse; the host receives and reacts to complete a working cycle. The proposal provides a proposal of a palm control mouse, and the track ball can only react to the palm action, so the proposal can not be popularized to the rehabilitation of the upper limbs of patients.

Disclosure of Invention

Based on the problems, the invention provides a rehabilitation training ball which can be applied to rehabilitation training of the upper limb motor function of a patient, overcomes the monotonicity and the boring property of the traditional exercise equipment and improves the interest of the patient in active exercise.

In order to achieve the aim of the invention, the invention adopts the following technical scheme: a rehabilitation training ball comprises a base, a track ball which is positioned above the base and can freely rotate, a microcomputer, a track ball rolling resistance adjusting mechanism and a track capturing module which can capture the rolling action of the track ball; the diameter of the track ball is matched with the size of the upper limb of the human body after the upper limb of the human body stretches; the track ball rolling resistance adjusting mechanism is provided with a friction piece which can be contacted with the surface of the track ball; the microcomputer is respectively connected with the track ball rolling resistance adjusting mechanism and the track capturing module in a signal mode, and the contact degree between the friction piece and the track ball surface is adjustable.

The rehabilitation training ball designed by the scheme comprises a base and a track ball, wherein the base is arranged below and can be placed on the ground generally. The track ball has huge size, is matched with the size of the upper limb of the human body after being stretched, and can be freely rotated and positioned above the base. In theory, the base can be arranged on the side of the track ball or even above the track ball, but the manufacturing cost is high, the assembly is difficult, and the practicability is not strong, so that the track ball is not considered. The track ball in the scheme has similar action as the track ball in the mechanical mouse, and the rolling action of the track ball can be captured by the track capture module to form corresponding electric signals to be input into the microcomputer. The track capturing module can be a structure similar to a mechanical mouse for capturing a track ball, or a small track ball is additionally arranged between the structure similar to the mechanical mouse for capturing the track ball and the track ball in the embodiment as an intermediary, and the structure similar to the mechanical mouse for capturing the track ball only captures the rotation action of the small track ball. The track ball rolling resistance adjusting mechanism is also designed beside the track ball, and friction is generated between the friction piece arranged on the track ball rolling resistance adjusting mechanism and the surface of the track ball, so that the rotating friction force of the track ball is increased. The track capturing module and the track ball rolling resistance adjusting mechanism are connected with the microcomputer through signals, the motion state of the track ball can be analyzed through a preset program of the microcomputer, and the friction force of the track ball rolling resistance adjusting mechanism to the surface of the track ball is correspondingly adjusted to form rolling resistance suitable for a trainer. Therefore, the trainer can open the arms, mobilize the corresponding muscle groups and nerve groups, and overcome certain resistance to push the track ball to rotate, so that the aim of rehabilitation training is fulfilled. Meanwhile, the action of pushing the track ball with large size can be diversified, the frequency can be high or low, and the directivity requirement is not strict, so that the training action is not monotonous, the fatigue feeling is not easy to generate, and the rehabilitation patient can use the track ball for a long time more easily. The track ball rolling resistance adjusting mechanism can be one or a plurality of track ball rolling resistance adjusting mechanisms; if a plurality of friction pieces are arranged, the friction pieces on each track ball rolling resistance adjusting mechanism can respectively form resistance corresponding to one direction of the track ball; in control, the microcomputer can control different friction pieces to form different resistances in different directions at the same time so as to meet different exercise requirements. To facilitate the device arrangement, it is preferable to place the microcomputer, the trackball rolling resistance adjustment mechanism, and the track capture module in the base.

Preferably, the track ball rolling resistance adjusting mechanism comprises a stepping motor controlled by a microcomputer and a fixed frame with fixed positions; the fixing frame is provided with a guide rail; the moving frame can slide on the guide rail under the control of the stepping motor; the end of the motion frame is provided with a friction piece, and the motion track of the friction piece is intersected with the spherical surface of the track ball. The power of the track ball rolling resistance adjusting mechanism designed by the scheme comes from the stepping motor. The action command of the stepping motor comes from the microcomputer. The position of the fixing frame is relatively fixed, a guide rail is designed on the fixing frame, a moving frame is arranged on the guide rail in a sliding mode, and a friction piece is arranged at the end portion of the moving frame. The moving frame is connected with the stepping motor, and the moving frame is driven to displace on the guide rail through the rotation of the stepping motor, so that the distance between the friction piece at the end part of the moving frame and the surface of the track ball is changed, and the friction resistance is adjusted.

Preferably, track ball limiting ribs are arranged on the base from the lower part of the track ball to the side or the upper part of the track ball, the number of the track ball limiting ribs is not less than 3, and the included angle between horizontal projections of two adjacent track ball limiting ribs is smaller than 180 degrees; the space body formed by enveloping the inner side wall of each track ball limiting rib is spherical, hemispherical or spherical crown shape which is matched with the track ball in size. In the scheme, a track ball limiting rib is designed for limiting the track ball. The lower end of the track ball limiting rib is connected to the base, and can extend to the upper side of the track ball along the lower side of the track ball. The number of the track ball limiting ribs is not less than 3, and the included angle between the horizontal projections of two adjacent track ball limiting ribs is smaller than 180 degrees, so that the track ball cannot deviate from the space between the two adjacent track ball limiting ribs. An envelope space is formed between the inner side walls of the track ball limit ribs, and the space can be spherical, for example, the track ball limit ribs extend to the upper part of the track ball one by one, and can be hemispherical or spherical crown, for example, the track ball limit ribs end at the side of the track ball. The envelope space is adapted to the shape and size of the track ball, so that the track ball is limited in the envelope space, and the track ball can roll freely and cannot fall off.

Preferably, the shell of the track ball is made of elastic materials; a plurality of universal balls are arranged on the inner side wall of the track ball limiting rib; the outer end of the universal ball is lapped with the surface of the track ball. In order to reduce friction and improve the rotating smoothness of the track ball between the track ball limiting ribs, a plurality of universal balls are arranged on the inner side walls of the track ball limiting ribs. The universal ball is also called a bullseye universal ball or a bullseye bearing, and the appearance is similar to that of a bullseye. The ball can be commercially available.

Preferably, the track ball is an inflatable ball, and the air pressure is controlled and adjustable by a microcomputer. The track ball designed by the scheme is inflatable, so that the contact resistance of the track ball rolling resistance adjusting mechanism can be better sensed. The microcomputer can finely adjust the air pressure in the track ball, for example, a mechanism for adjusting the temperature of the air in the track ball to change the air pressure in the track ball along with the air pressure, so that the touch feeling of a rehabilitation patient on the track ball during training can be changed, and different personalized using effects are formed.

Preferably, the system is also provided with an image output device which is connected with the microcomputer through signals; software simulating the real physical environment is installed in the microcomputer, and the software drives the track ball rolling resistance adjusting mechanism to adjust the rolling resistance of the track ball when the image of the software is output to the image output equipment. The image output device may be a display screen, a projection, a wearable display system, a VR, or the like. The microcomputer is internally provided with a program for simulating the real physical environment, such as the condition of a fluctuant road surface, the physical characteristics of the track ball when the track ball rolls on the fluctuant road surface are formed by the track ball rolling resistance adjusting mechanism, the pushing force effect of a rehabilitation patient is formed by feedback, and the fluctuant road surface is transmitted to the vision of the rehabilitation patient by the image output equipment, so that the rehabilitation patient can feel on the scene to push a big ball to advance on the fluctuant road surface, the monotonicity of the rehabilitation training is further overcome, and the training process is more diversified and interesting. Of course, the trackball can also be defined as a big ball floating on the water surface by the program control of software, and the training process of the patient is similar to pushing the big ball on the water surface. Such a program development direction is not uniform and will not be described here.
