Description

Technical Field

[0001] The utility model belongs to the technical field of rehabilitation medical equipment, and specifically relates to a home hand function rehabilitation auxiliary appliance. Background Art

[0002] Hand rehabilitation training is an important step to help restore hand function, especially for hand function limitation caused by hand trauma, central nervous system damage or peripheral nerve damage. It can improve symptoms such as limited joint movement of palm and fingers, muscle atrophy, sensory impairment, etc. It includes finger flexibility training, finger muscle training and hand coordination training.

[0003] Traditional hand rehabilitation training equipment can be divided into two categories according to the driving mode:

[0004] First, electric rehabilitation training equipment: At the joints of plastic movable buckle gloves, micro motors are used to control the movable inclination angles of these joints using preset programs to achieve the bending and straightening of fingers, so that the entire palm can grasp and open. However, since the inflation process does not separate the proximal and distal interphalangeal joints, the joints cannot be moved to the functional position;

[0005] Second, pneumatic rehabilitation training equipment: multiple air bags are installed on the plastic movable buckle gloves, which can be inflated and exhausted manually or with an air pump to drive finger movements.

[0006] Third, the size and degree of deformity of patients’ fingers are different, and gloves cannot be tailored to each person, have no elasticity, and cannot fit the fingers accurately.

[0007] When the existing hand rehabilitation training equipment is worn on the hand, a massage ball with several protrusions is often installed on the palm, and these protrusions are used to intermittently stimulate the active palm. The massage ball needs to fit the palm, and the airbags on the fingers are tightened by elastic bands for resetting. Since the massage ball and the elastic band are soft and easily deformed, the finger airbags cannot be limited, resulting in the problem that the finger airbags are easily tilted left and right during rehabilitation training. For this reason, we propose a home hand function rehabilitation auxiliary device. Utility Model Content

[0008] The utility model aims to provide a hand function rehabilitation auxiliary device at home, which can form a triangular stability structure with a finger airbag, two baffles and two rubber bands, so as to conveniently and stably support five fingers and reduce the degree of left and right tilting of the finger airbag during rehabilitation training.

[0009] The technical solutions adopted in this utility are as follows:

[0010] A hand function rehabilitation auxiliary device for home use comprises five finger airbags, a massage column is fixed between the ends of the five finger airbags close to each other, baffles are fixed at the positions on both sides of the finger airbags on the outside of the massage column, the baffles are parallel to the central axis of the massage column and have a slope on the side away from the corresponding finger airbags, rubber bands are fixed on both sides of the five finger airbags, one end of the rubber bands extends along the slope of the adjacent baffles and is fixedly connected to the outside of the massage column, two Velcro strips are fixed at intervals on the outside of the five finger airbags, and a micro air pump connected to the five finger airbags is also included, so that during rehabilitation training, the patient is helped to place the palm on the upper surface of the massage column with the five fingers falling on the corresponding On the finger airbags, two Velcros are used to surround the fingers from both sides and stick them together to restrain the fingers, and the micro air pump is started to intermittently inflate the five finger airbags, so that the end of the five finger airbags away from the massage column expands first, and the five fingers of the patient can be lifted upward, and two baffles are used to straighten the finger airbags from both sides, and the two rubber bands are tightened in an eight-shaped shape, so that the finger airbags, two baffles and two rubber bands form a triangular stability structure, which is convenient and stable to support the five fingers and reduce the left and right skewness of the finger airbags during rehabilitation training. After the fingers are straightened, the micro air pump is controlled to exhaust, and the five finger airbags shrink and retract into the middle of the two baffles for accurate resetting.

[0011] The micro air pump signal is connected to a single chip microcomputer, and a program can be written to control the inflation or exhaust time of the micro air pump.

[0012] Branch air tubes are fixed between the output end of the micro air pump and one end of the five finger air bags, and they have sufficient excess length so that the micro air pump will not be pulled after the five finger air bags are expanded.

[0013] The upper surface of the massage column is provided with a plurality of grooves, and volcanic magnets are fixed on the lower edges of the grooves. In this way, the natural magnetic field of the volcanic magnets acts on the palms, stimulates the acupuncture points of the palms, accelerates the recovery progress, and is hidden inside the grooves so as not to hurt the palms. In addition, the plurality of grooves increase the friction surface between the massage column and the palms, thus playing an anti-slip role.

[0014] The massage column is of a hollow structure and a lifting airbag is fixed on its lower wall. A secondary air pipe is fixed between one side of the lifting airbag and the output end of the micro air pump. After the micro air pump is started, while inflating the finger airbags, it also inflates the lifting airbag along the secondary air pipe, so that the lifting airbag pushes the volcanic magnet part upward and extends out of the groove, intermittently hitting the palm of the hand to achieve a massage effect.

[0015] The lower ends of the volcanic magnets extend into the interior of the massage column and are fixed with limit plates. The limit plates are arranged just above the lifting airbags to limit the position and prevent the volcanic magnets from completely falling out of the grooves.

[0016] The technical effects achieved by this utility model are:

[0017] The utility model discloses a hand function rehabilitation auxiliary tool for home use. During rehabilitation training, the patient is helped to place the palm of the hand on the upper surface of a massage column and five fingers fall on corresponding finger air bags, two Velcro strips are used to respectively surround the fingers from two sides and bond them together to restrain the fingers, a micro air pump is started to intermittently inflate the five finger air bags, so that the end of the five finger air bags away from the massage column is expanded first, and the five fingers of the patient can be lifted upward, and two baffles are used to respectively straighten the finger air bags from two sides, and two rubber bands are tightened in an eight-shaped shape, so that the finger air bags, two baffles and two rubber bands form a triangular stability structure, which is convenient and stable to support the five fingers, and reduce the degree of left and right skewness of the finger air bags during rehabilitation training. After the fingers are straightened, the micro air pump is controlled to exhaust air, and the five finger air bags are contracted and retracted into the middle of the two baffles, so as to be accurately reset.

[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0025] like Figure 1-4As shown, a home hand function rehabilitation auxiliary device includes five finger airbags 1, a massage column 2 is fixed between the ends of the five finger airbags 1 that are close to each other, the upper edge of the massage column 2 is fixedly connected to the ends of the five finger airbags 1 that are close to each other, baffles 3 are fixed to the positions on the outside of the massage column 2 on both sides of the finger airbags 1, the bottom surfaces of the baffles 3 are bonded to the outside of the massage column 2, the baffles 3 are parallel to the central axis of the massage column 2 and have a slope on the side away from the corresponding finger airbag 1, rubber bands 4 are fixed on both sides of the five finger airbags 1, one end of the rubber band 4 extends along the slope of the adjacent baffle 3 and is fixedly connected to the outside of the massage column 2, and the other end thereof is bonded to one side of the adjacent finger airbag 1, two Velcros 5 are fixed at intervals on the outside of the five finger airbags 1, one side of the Velcro 5 is bonded to the outside of the adjacent finger airbag 1, and also includes a micro air pump 6 connected to the five finger airbags 1, The bottom surface of the column 2 is wide and stands stably on the desktop. During rehabilitation training, the patient is helped to place the palm of the hand on the upper surface of the massage column 2 and the five fingers fall on the corresponding finger airbags 1. Two Velcro strips 5 are used to surround the fingers from both sides and stick them together to restrain the fingers. The micro air pump 6 is started to intermittently inflate the five finger airbags 1, so that the end of the five finger airbags 1 away from the massage column 2 is preferentially expanded, and the five fingers of the patient can be lifted upward. The two baffles 3 are used to straighten the finger airbags 1 from both sides, and the two rubber bands 4 are tightened in an eight-shaped shape, so that the finger airbags 1, the two baffles 3 and the two rubber bands 4 form a triangular stability structure, which is convenient and stable to support the five fingers and reduce the degree of left and right skewness of the finger airbags 1 during rehabilitation training. After the fingers are straightened, the micro air pump 6 is controlled to exhaust, and the five finger airbags 1 shrink and retract into the middle of the two baffles 3 for accurate resetting.

[0026] The micro air pump 6 can be purchased from the market as a 7A12D45R29 DC brushless oil-free piston pump with a rated power of 30KW and a rated voltage of 12 / 24V. It can be started silently and can rotate forward to inhale or reverse to exhaust.

[0027] Moreover, the shape of the massage column 2 is not limited to that shown in the drawings, it can be a truncated cone, so that the height of the five finger airbags 1 is raised, so that the five finger airbags 1 expand and drive the palm to stretch as flat as possible, and the patient's wrist can be fixed with a strap to prevent slipping.

[0028] like Figure 1 and Figure 2 As shown, the micro air pump 6 is signal-connected to a single-chip microcomputer 7 , which can be a Mitsubishi series controller purchased on the market, and can be programmed to control the inflation or exhaust time of the micro air pump 6 .

[0029] like Figure 1 and Figure 3As shown, branch air tubes 8 are fixed between the output end of the micro air pump 6 and one end of the five finger airbags 1. The micro air pump 6 maintains air communication with the five finger airbags 1 through the branch air tubes 8. They have sufficient excess length so that the five finger airbags 1 will not pull the micro air pump 6 after they are inflated.

[0030] like Figure 2 and Figure 4 As shown, a plurality of grooves 9 are provided on the upper surface of the massage column 2, and volcanic magnets 10 are fixed to the lower edges of the grooves 9. In this way, the natural magnetic field of the volcanic magnets 10 acts on the palm, stimulates the palm acupuncture points, accelerates the recovery progress, and is hidden inside the grooves 9 without rubbing the palm. In addition, the plurality of grooves 9 increase the friction surface between the massage column 2 and the palm, playing an anti-slip role.

[0031] like Figure 1 and Figure 2 As shown, the massage column 2 is a hollow structure and a lifting airbag 11 is fixed to its lower wall. A secondary air pipe 12 is fixed between one side of the lifting airbag 11 and the output end of the micro air pump 6. The micro air pump 6 maintains air communication with the lifting airbag 11 through the secondary air pipe 12. After the micro air pump 6 is started, while inflating the finger airbag 1, it also inflates the lifting airbag 11 along the secondary air pipe 12, so that the lifting airbag 11 pushes the volcanic magnet 10 upward to partially extend out of the groove 9 and intermittently hit the palm of the hand to achieve a massage effect.

[0032] like Figure 2 and Figure 4 As shown, the lower ends of the volcanic magnets 10 extend into the massage column 2 and are fixed with limit plates 13. The limit plates 13 are arranged directly above the lifting airbags 11 to limit and prevent the volcanic magnets 10 from completely escaping from the grooves 9.

[0033] The working principle of the utility model is as follows: during rehabilitation training, the patient is helped to place the palm on the upper surface of the massage column 2 and five fingers fall on the corresponding finger airbags 1, and two Velcro strips 5 are used to surround the fingers from both sides and bond them together to restrain the fingers.

[0034] At the same time, the micro air pump 6 is started to intermittently inflate the five finger airbags 1, so that the end of the five finger airbags 1 away from the massage column 2 expands first, and the five fingers of the patient can be lifted upward, and the two baffles 3 are used to straighten the finger airbags 1 from both sides, and the two rubber bands 4 are tightened in an eight-shaped shape, so that the finger airbags 1, the two baffles 3 and the two rubber bands 4 form a triangular stability structure, which is convenient for stably supporting the five fingers and reducing the left and right skewness of the finger airbags 1 during rehabilitation training.

[0035] After the fingers are straightened, the micro air pump 6 is controlled to exhaust air, and the five finger airbags 1 shrink and retract into the middle of the two baffles 3 for accurate resetting.

[0036] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
