Description

Technical Field

[0001] The present invention relates to the technical field of hand tremor suppression equipment, and in particular to a wearable hand tremor suppressor. Background Art

[0002] The causes of hand tremor are complex and can be divided into two categories: primary and secondary. Primary tremor is represented by essential tremor, which is common in the middle-aged and elderly population. Secondary tremor may be caused by Parkinson's disease, hyperthyroidism, alcohol withdrawal syndrome and other diseases. Among them, alcoholics are a typical group, which is caused by long-term drinking. Hand tremor not only causes great inconvenience to the patient's daily life, but also seriously affects the patient's work ability, especially fine movements.

[0003] At present, the treatments for hand tremors mainly fall into two categories: drugs and auxiliary equipment. Although drug treatment is effective in some cases, its effect is relatively limited and may bring side effects such as drowsiness, fatigue or low blood pressure. For alcoholics, the drug effect is even more difficult to achieve the ideal level.

[0004] Regarding auxiliary equipment, in the invention patent with Chinese patent publication number CN108670512B, a wrist tremor suppression device based on particle damping technology is provided. When the user's wrist trembles, the particle damper is driven to perform reciprocating linear motion on the ball linear guide, thereby utilizing the energy absorption capacity of the particle damper to suppress the tremor movement of the wrist and achieve the effect of suppressing hand tremors.

[0005] However, in practical applications, we found that the above auxiliary equipment still has certain shortcomings, such as: The amplitude of hand tremors is not large in itself, and existing devices find it difficult to effectively capture tremor signals, which leads to insufficient suppression effects. This is because traditional suppression devices directly rely on the tremor amplitude to suppress hand tremors. However, when the hand tremor amplitude is small, insufficient drive will cause the device's response effect to drop significantly, making it difficult to achieve an ideal tremor suppression effect, especially for patients with mild hand tremors. Summary of the invention

[0022] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0023] Embodiment 1: See also Figure 1-Figure 5 A wearable hand tremor suppressor comprises an arm pad 2 fixed to the top surface of the forearm by a strap 3, and a glove 1 worn on the hand, such as Figure 3 As shown, a shell 4 is fixedly installed on the top of the arm pad 2, an inner box 5 is arranged in the shell 4, a left baffle 6 and a right baffle 7 are arranged vertically and parallelly in the inner box 5, a floating plate 8 is movably arranged in the middle interlayer, and the left and right sides of the floating plate 8 are supported by positioning springs 9, so that the floating plate 8 can be located in the middle position of the interlayer; In this embodiment, a traction rod 10 is fixedly installed on the side of the floating plate 8 facing the glove 1. The end of the traction rod 10 passes through the left baffle 6 and is connected to a pull rod 11 through a displacement amplifier. The end of the pull rod 11 passes through the inner box 5 and the shell 4 and is movably connected to a movable rod 14. The other end of the movable rod 14 is fixed on the back of the glove 1. Figure 2 As shown, a ball sleeve 12 is fixedly mounted on one end of the pull rod 11 outside the housing 4, a rotating ball 13 is rotatably arranged in the ball sleeve 12, and the rotating ball 13 is fixed to the end of the movable rod 14, so that the movable rod 14 can rotate freely, thereby allowing the hand to move freely; When the hand shakes, the tremor of the hand pulls (pushes or pulls) the pull rod 11 to move through the movable rod 14. The movement of the pull rod 11 is amplified by the displacement amplifier and then drives the floating plate 8 to move through the traction rod 10. Through the coordinated design of the floating plate 8 and the positioning spring 9, the supporting force provided by the positioning spring 9 can be used to elastically limit the floating plate 8, thereby effectively absorbing and buffering the tremor movement of the hand, realizing real-time suppression of the hand shake and reducing the amplitude of the hand shake.

[0024] Through the displacement amplifier, the slight tremor displacement signal generated by the hand can be amplified, so that the floating plate 8 can move a longer distance, thereby ensuring that the suppressor can accurately respond to the tremor. Even if the tremor amplitude is small, the suppression function can be triggered. Specifically, when the hand shakes, the movable rod 14 drives the pull rod 11 to produce a slight movement, and the slight movement of the pull rod 11 can cause the traction rod 10 and the floating plate 8 to produce obvious displacement after passing through the displacement amplifier.

[0025] In the present invention, the displacement amplifier includes a moving plate 15, a middle rod 16, a front hinge rod 17, a front fixed seat 18, a rear hinge rod 19, a rear fixed seat 20 and a push-pull plate 21. Specifically, Figure 3 and Figure 4 As shown, one end of the pull rod 11 located inside the inner box 5 is fixedly mounted on the movable plate 15, and the movable plate 15 is movably arranged in the inner box 5, and two middle rods 16 are rotatably mounted in the middle of the front and rear sides through fixed shafts, and are X-shaped and crossed. The front end of the middle rod 16 is hinged with a front hinge rod 17, and the other end of the front hinge rod 17 is rotatably mounted on a front fixed seat 18, and the front fixed seat 18 is fixedly mounted on the inner side wall of the inner box 5. The rear end of the middle rod 16 is hinged with a rear hinge rod 19, and the other end of the rear hinge rod 19 is rotatably mounted on a rear fixed seat 20, and the rear fixed seat 20 is fixedly mounted on a push-pull plate 21, and the push-pull plate 21 is movably arranged in the inner box 5, and the traction rod 10 is fixedly mounted on the push-pull plate 21; When the pull rod 11 produces a small displacement, it will synchronously drive the moving plate 15 to move. When the moving plate 15 moves, the cross-amplification effect of the X-shaped middle rod 16 can amplify the displacement stroke and transmit it to the push-pull plate 21, so that the push-pull plate 21 produces a larger displacement. The push-pull plate 21 produces a larger displacement, which makes the traction rod 10 and the floating plate 8 have a larger displacement.

[0026] In this embodiment, a guide rod 22 is movably inserted on the movable plate 15 and the push-pull plate 21. The guide rod 22 is fixedly installed on the inner wall of the inner box 5 to guide and direct the movable plate 15 and the push-pull plate 21 so that the movable plate 15 and the push-pull plate 21 can perform a more stable translational movement.

[0027] Embodiment 2: See also Figure 5 and Figure 6On the basis of the first embodiment, in the present embodiment, the left baffle plate 6 and the right baffle plate 7 are both movably arranged in the inner box 5, and the distance between the two can be adjusted by an adjusting mechanism. By adjusting the distance between the left baffle plate 6 and the right baffle plate 7, the pre-compression degree of the two positioning springs 9 can be controlled, thereby flexibly adapting to the needs of patients with different hand tremor amplitudes. For patients with larger hand tremor amplitudes, the positioning spring 9 can be pre-compressed tighter, and for patients with smaller hand tremor amplitudes, the positioning spring 9 can be pre-compressed looser.

[0028] In this embodiment, the adjustment mechanism includes a control cabinet 27, a threaded rod 28 and a nut 30. Specifically, Figure 5 As shown, a control cabinet 27 is fixedly installed on the top of the inner box 5, and a threaded rod 28 is rotatably installed in the control cabinet 27. The two sides of the outer wall of the threaded rod 28 are respectively formed with left-handed threads and right-handed threads with opposite rotation directions. The outer walls of the left-handed threads and the right-handed threads are both threadedly connected with nuts 30. The left baffle plate 6 and the right baffle plate 7 are respectively fixedly connected with the two nuts 30 through two connecting blocks. In addition, one end of the threaded rod 28 is rotatably installed on the inner side wall of the control cabinet 27, and the other end extends to the outside of the control cabinet 27 and is fixedly connected with a dial wheel 29. When the thumbwheel 29 is turned by a finger, the threaded rod 28 can be driven to rotate. When the threaded rod 28 rotates, the two nuts 30 can move in opposite directions through the left-handed thread and the right-handed thread, and move closer to or away from each other (depending on the positive and negative turning of the thumbwheel 29). When the two nuts 30 move closer to or away from each other, the distance between the left baffle 6 and the right baffle 7 can be adjusted.

[0029] Embodiment three: See also Figure 3 and Figure 5 On the basis of the first or second embodiment, in this embodiment, the inner box 5 is slidably mounted in the housing 4, and a tail rod 23 is fixedly mounted on the end facing away from the glove 1. Figure 5 As shown, a piston 24 is fixedly installed at the end of the tail rod 23, and the piston 24 is movably arranged in an oil cylinder 25, and the oil cylinder 25 is fixedly installed in the housing 4. Oil holes 26 (fine holes) are evenly opened on the piston 24, and the oil cylinder 25 is filled with damping oil; Thus, the entire inner box 5 can move in the housing 4 and drive the piston 24 to move through the tail rod 23. When the piston 24 moves, the damping oil passes through the oil hole 26 to provide a damping force.

[0030] In practical applications, when the hand shakes, the displacement amplifier, floating plate 8 and positioning spring 9 in the inner box 5 can suppress the hand shake; when the wrist is folded, the movement of the hand will exceed the stroke of the displacement amplifier, and then pull the entire inner box 5 to move. When the inner box 5 moves, the damping oil provides damping for the movement. After the wrist is folded in place, the inner box 5 can be kept in a predetermined position by the damping force, while the displacement amplifier, floating plate 8 and positioning spring 9 can still work normally to suppress the hand shake. In this way, through the damping design of the piston 24 in the oil cylinder 25, it is possible to allow the wrist to be freely folded within a certain range while not affecting the device's function of suppressing hand shake.

[0031] Embodiment 4: See also Figure 7 On the basis of the first embodiment, the second embodiment or the third embodiment, in this embodiment, a sliding rheostat is further provided in the bottom groove 33 provided on the arm pad 2, and the sliding piece 31 of the sliding rheostat is installed at the bottom of the floating plate 8 and can move with the floating plate 8; Specifically, Figure 7 As shown, the slide 31 is fixedly mounted on the bottom of the floating plate 8 and is slidably sleeved on the conductive rod 32. The bottom end of the slide 31 contacts the resistance wire on the porcelain tube 34, and the porcelain tube 34 is fixedly mounted in the bottom groove 33. In addition, the wire 1 35 is connected to the right end of the resistance wire, and the wire 2 36 is connected to the left end of the conductive rod 32. When the floating plate 8 moves due to hand tremor, the slide 31 moves on the conductive rod 32 and the porcelain tube 34, changing the contact position of the resistance wire, thereby changing the total resistance value in the circuit. Through the change of the resistance value, the sliding rheostat can make the current in the circuit change accordingly. By monitoring the changes in current, the amplitude and frequency of hand tremors can be indirectly reflected, thereby providing real-time hand shake monitoring data. At the same time, the monitoring data is obtained after displacement amplification through a displacement amplifier, so the monitoring accuracy is effectively guaranteed.

[0032] The specific circuit structure can be arranged by technicians in this field according to actual needs. For example, wire one 35 is connected to the positive pole of the power supply, and wire two 36 is connected to the negative pole to form a closed loop. Then a current sensor is connected in series to wire two 36 to monitor the current size. The monitored data can be transmitted to the host computer for analysis.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
