Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a wearable tremor treatment device. Background Art

[0002] Tremor is defined as an involuntary, oscillatory movement of a body part, and pathological tremor is considered the most common movement disorder. Since tremor is ultimately caused by abnormal muscle activity patterns, studies have shown that external feedback (i.e., electrical stimulation) has a positive effect on suppressing tremor. This external feedback is non-invasive, easy to apply, and requires minimal hardware. For example, when electrodes are placed on the radial and median nerves and electrical stimulation is applied, low-level current pulses are delivered to the tissue, which can depolarize the motor nerves and induce muscle contraction. Studies have shown that non-invasive electrical stimulation of the median and radial nerves at the wrist, alternating at a frequency consistent with the wearer's tremor frequency, modulates the ventral intermediate nucleus, thereby reducing tremor in patients with essential tremor (ET). Summary of the invention

DETAILED DESCRIPTION

[0030] To describe the technical content, structural features, achieved purpose and effect of the utility model in detail, the technical scheme in the embodiment of the present application will be described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, rather than all the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the utility model. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the invention of this patent, the utility model will have various changes and improvements, and the scope of protection required by the utility model is defined by the attached claims, description and their equivalents.

[0032] The wearable tremor treatment device of the present application can be worn on the patient's limbs, such as wrists, arms, ankles, thighs, calves, etc., to detect the patient's tremor amplitude and indirectly stimulate the patient's ventral intermediate nucleus of the thalamus by applying non-invasive electrical stimulation to the nervous system of the patient's limbs, thereby alleviating the patient's tremor response.

[0033] See also Figure 1 , 2 As shown, it is an embodiment of the present application, which discloses a wearable tremor treatment device that can be worn on the wrist of a user. The overall size and shape are similar to a watch or a sports bracelet. It can not only have the function of applying pulse stimulation signals to the human body, but also integrate common time display, network connection, motion detection and other functions. In particular, in some embodiments, function expansion can also be achieved by configuring appropriate application software (APP).

[0034] See also Figure 1 , 2 , 7, 8, in this embodiment, the tremor treatment device includes a stimulator body 100 and a belt assembly 200 detachably connected to the stimulator body 100.

[0035] Specifically, the stimulator body 100 further includes components such as a display screen 110 , a main control circuit 120 , a battery 130 , a frame 140 , a switch 150 , a transparent cover 161 , a back cover 162 , and a vibration motor 170 .

[0036] In one embodiment, the main control circuit 120 integrates electronic devices such as a power supply module, a main control unit, a sensor, a skin impedance monitoring module, a stimulation signal generating module, a signal output terminal, an aviation male plug 124, and a Bluetooth module. Among them, the sensor can be a motion sensor, typically an accelerometer, a gyroscope, an inclinometer, a magnetometer, etc. The sensor can also be a biosensor that can reflect muscle discharge or nerve discharge.

[0037] The stimulation signal generating module on the main control circuit 120 is connected to the signal output terminal, and the signal output terminal is conductively connected to the aviation male plug 124 to transmit the pulse stimulation signal generated by the stimulation signal generating module to the conductor 250 and the stimulation electrode.

[0038] Please continue to refer to Figure 1 , 2 The stimulator body 100 has a first button 121 for turning on and off, a second button 122 for increasing the adjustment, and a third button 123 for decreasing the adjustment. The second button 122 and the third button 123 can be configured to adjust the time, adjust the size of the pulse stimulation current, turn pages up and down, etc.

[0039] At least one pair of charging terminals 131 and a magnet (not shown) disposed adjacent to the pair of charging terminals are also disposed on the back cover plate 162 of the stimulator body 100. The pair of charging terminals 131 are electrically connected to the main control circuit 120, and the main control circuit 120 is connected to the battery 130. Therefore, the pair of charging terminals 131 can realize the electrical connection between the external charging device and the main control circuit 120 and the battery 130, thereby realizing battery charging. The magnet is used to enable the stimulator body 100 to be adsorbed on the external charging device to avoid disconnection.

[0040] It is particularly important to point out that a grounding electrode 141 is also provided on the back cover 162 of the stimulator body 100, and the grounding electrode is connected to the grounding terminal of the main control circuit 120. The grounding electrode and the stimulating electrode are in contact with the human skin at the same time to form a complete circuit.

[0041] In another embodiment of the present application, the belt assembly 200 includes a quick-release connection belt 210 and an adjustment belt 220. The first end of the quick-release connection belt 210 can be quickly connected or removed from the stimulator body 100 through a belt connector. The quick-release connection belt 210 is made of a polymer waterproof material, such as silica gel, PVC, etc., and the adjustment belt 220 is made of a flexible fabric, and a structure such as a Velcro or a buckle is provided on one side of the fabric.

[0042] See also Figure 2 , 3 4, a hollow buckle 213 is provided on the second end of the quick-release connecting belt 210, and one end of the adjusting belt 220 passes through the buckle 213, bypasses the ear on the side of the stimulator body 100, and is pasted or fixed on the other end of the adjusting belt 220. By adjusting the overlapping length of the adjusting belt 220, the total length of the belt assembly can be adjusted to meet the wearing requirements of different patients and different parts.

[0043] See also Figure 3 , 4As shown, a stimulation electrode 230 is disposed inside the quick-release connection belt 210, and a conductor 250 electrically connected to the stimulation electrode 230 is embedded inside the quick-release connection belt 210. The conductor 250 is made of a flexible printed circuit (FPC) that can be bent repeatedly. The number of stimulation electrodes 230 can be one or more. Figure 3 , 4 In the illustrated embodiment, two stimulation electrodes 230 are disposed on the quick-release connection belt 210, one stimulation electrode 230 protrudes from the surface of the quick-release connection belt 210, and the other is flush with the surface of the quick-release connection belt. The conductive plates of the two stimulation electrodes: the first conductive plate 232 and the second conductive plate 242 are both conductively connected to the conductor 250 on one side, while the other sides of the first conductive plate 232 and the second conductive plate 242 are exposed on the inner surface of the quick-release connection belt 210, so that when the consumer wears the tremor treatment device of the present application, the first conductive plate and the second conductive plate can directly contact the human skin. In other embodiments of the present application, the first conductive plate and the second conductive plate can also be adsorbed with other types of electrodes for use, such as wet electrodes, gel electrodes, or other electrodes with different conductivity.

[0044] In one embodiment, in order to allow the stimulation electrode 230 to better contact the human body, the stimulation electrode 230 also has a protruding base 231. The base 231 can be adjusted according to the wearing position of the tremor treatment device to achieve the purpose of fitting the human body as closely as possible and filling the gap between the stimulation electrode and the human skin.

[0045] The base can be made of the same silicone material as the quick-release connecting belt 210, or a flexible sponge foam material. In particular, the shape of the base depends on the part to be worn and the size of the gap to be filled, such as Figure 3 , 4 In the illustrated embodiment, in order to fill the gap between the patient's wrist and the quick-release connecting belt, the base 231 is designed to be thicker on the side close to the stimulator body and thinner on the side away from the stimulator body, and the thickness of the two ends of the base gradually transitions to form a wedge-shaped structure, and the first conductive plate 232 also has a wedge-shaped structure with one side thicker and the other side narrower.

[0046] In order to achieve a quick connection between the belt assembly 200 and the stimulator body 100, a belt connector is provided at the first end of the quick-release connecting belt 210, and a slot capable of adapting to the belt connector and a switch 150 for removing the belt connector are provided on the frame 140 of the stimulator body 100. When the belt connector is connected to the stimulator body, mechanical connection and electrical connection between the main control circuit and the conductor and each stimulation electrode can be achieved at the same time.

[0047] Please continue to see Figure 3 , 4The connector includes an electrical plug connector 211 and a mechanical plug connector 212. In this embodiment, the electrical plug connector 211 and the mechanical plug connector 212 are constructed on the same component. In other embodiments, the electrical plug connector 211 and the mechanical plug connector 212 can also be separated into two independent components, or integrated into one component, as long as they can be inserted once and play the role of electrical connection and mechanical connection at the same time, they all belong to the inventive concept of this application.

[0048] See also Figure 5 , 7 As shown, an aviation male plug 124 conductively connected to the main control circuit 120 is installed in the stimulator body 100, and the electrical plug connector 211 has a first plug base 2111 that can be plugged into the slot and an aviation female plug 2113 buried in the first plug base 2111, and the end of the aviation female plug 2113 passes through the conductor 250 and is threadedly fastened to the fixing nut 2114. When the belt connector is connected to the stimulator body, the aviation male plug 124 is plugged into the aviation female plug 2113 and forms electrical conduction with the conductor 250.

[0049] See also Figure 6 , 8 As shown, the mechanical plug connector 212 includes a second plug base 2124, a fixed cover plate 2121 ultrasonically welded on the second plug base 2124, and a movable portion 2123 elastically connected to the second plug base 2124 through a second elastic member 2122. The second elastic member 2122 is retracted along the second direction, so that the movable portion 2123 can move along the second direction under the action of an external force, and is retracted within the second plug base 2124, or protrudes from the second plug base 2124.

[0050] When the mechanical plug connector 212 is inserted into the slot along the first direction, the movable portion 2123 shrinks in the second plug base 2124 until the mechanical plug connector 212 reaches the designated plugging position, and the movable portion 2123 extends out of the second plug base 2124 along the second direction under the action of the second elastic member 2122. At this time, the movable portion 2123 abuts against the slot on the inner side of the frame 140 to prevent the mechanical plug connector 212 from exiting the slot in a direction opposite to the first direction, thereby achieving a reliable connection between the belt assembly 200 and the stimulator body 100. Preferably, the second direction is perpendicular to the first direction.

[0051] When the belt assembly 200 is disassembled, the switch 150 is needed, and the switch 150 is movably connected to the back cover 162 of the stimulator body 100. The switch 150 includes a button body 151, a first elastic member 152 between the button body and the back cover 162, a push rod 153, and a pair of hooks 155. The switch 155 is hooked on the back cover 162 by a pair of hooks 155 to prevent it from falling off. When the belt assembly 100 is connected to the stimulator body 100, the position of the movable part 2123 abuts against the push rod 153. Therefore, it is only necessary to apply an external force along the second direction to the button body 151 to push the push rod 153, so that the movable part 2123 is retracted back into the second plug base 2124, leaving the position that prevents the mechanical plug from exiting the slot. At this time, the belt connector can be smoothly taken out from the slot of the stimulator body.

[0052] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the invention, the utility model may have various changes and improvements, and the scope of protection required by the utility model is defined by the attached claims, description and their equivalents.
