Description

TECHNICAL FIELD

[0001] The utility model relates to wearable medical instrument technical field, especially to a kind of intelligent wrist -watch of noninvasive regulation chest sympathetic nerve treatment primary palmar hyperhidrosis. BACKGROUND

[0002] Primary palmar hyperhidrosis is a functional local abnormality of unknown pathogenesis, which is caused by the abnormal increase of chest sympathetic nerve excitability that dominates hand sweat gland, leading to abnormal secretion of hand sweat gland that is not affected by external temperature. The symptoms are abnormal increase of palm perspiration caused by tension, excitement, stress or hot weather, and even worse consequences, such as frostbite of fingers, cannot be avoided even in cold weather.

[0003] At present, the non-surgical treatment of primary palmar hyperhidrosis mainly relies on drug treatment, which has short-term effect and cannot be maintained. When the drug effect disappears, the symptoms of palmar hyperhidrosis will gradually recover. Although repeated treatment is still effective, long-term oral or injection of drugs has many side effects, and the operation technique is difficult, and the adverse reactions of drugs increase. Surgical treatment mainly relies on thoracic surgery of thoracic sympathetic nerve and communicating branch amputation, which requires high anesthesia technology and perioperative monitoring, and has the risk of common complications of thoracic surgery such as traumatic pneumothorax, persistent air leakage, bleeding and effusion. The symptoms of palmar hyperhidrosis are relieved to some extent within 2 years after surgery. But more than 2 years after surgery, the symptoms of palmar hyperhidrosis will be progressively aggravated with the growth of postoperative time. Many patients will immediately appear other parts of postoperative compensatory sweating, excessive dryness of palm, and side effects such as denervation after surgery, which makes the quality of life worse than before surgery. Thoracic sympathetic nerve chain amputation causes permanent damage to the anatomical structure and physiological function of sympathetic nerve, which cannot be repaired. The safety and effectiveness of surgery are controversial in the international medical community. Some health administrative departments in some countries and regions have banned this surgery.

[0004] Smartwatch devices are increasingly used in modern medical and health care practices. Using a watch form for treatment has outstanding practical significance for protecting patient privacy and reducing treatment accessibility. SUMMARY

[0010] The third stimulation electrode is positioned corresponding to the surface area of ​​the ulnar nerve in the wrist. The third stimulation electrode is connected to the pulse generator and emits the pulse signal to the surface area of ​​the ulnar nerve.

[0033] The following description of the implementation process of the technical solution of this utility model with reference to specific embodiments is not intended to limit the utility model.

[0034] This invention provides a smartwatch for the non-invasive treatment of primary palmar hyperhidrosis by regulating the thoracic sympathetic nerve.

[0035] According to this utility model, when the smartwatch is worn on the wrist, a stimulation electrode is provided at the component corresponding to the palm side to provide pulsed electrical stimulation to the surface of a specific nerve in the wrist. This allows the nerve electrical signal to be transmitted through the nerve trunk and spinal cord to the thoracic sympathetic nerve, stimulating the release of corresponding neurotransmitters in the brain and spinal cord, thereby inhibiting the excitation of the thoracic sympathetic nerve and controlling excessive sweating of the hands.

[0036] This invention utilizes a non-invasive, accompanying intelligent recognition and continuous treatment method that is convenient, effective, and low-cost for neuromodulation, demonstrating excellent efficacy in treating primary palmar hyperhidrosis while reducing treatment costs.

[0037] like Figure 1 The diagram shows a schematic representation of the structure of a smartwatch for the non-invasive treatment of primary palmar hyperhidrosis using thoracic sympathetic nerve modulation. Other common functional modules of the smartwatch are not shown in the figure.

[0038] like Figure 2 The diagram shows the distribution of nerves in the human hand.

[0039] like Figure 3 The diagram shows the surface locations of the radial nerve, median nerve, and ulnar nerve.

[0040] like Figure 4 The diagram shows the functional framework of a smartwatch for the non-invasive treatment of primary palmar hyperhidrosis using thoracic sympathetic nerve modulation.

[0041] The smartwatch 100 has a watch face and a watch band. The watch band is equipped with a first stimulation electrode 10, a second stimulation electrode 20, and a third stimulation electrode 30. The watch face contains a main controller 40 and a pulse generator 50. The main controller 40 is connected to the first stimulation electrode 10, the second stimulation electrode 20, and the third stimulation electrode 30 through a transmission circuit, which is embedded in the watch band.

[0042] The human arm contains the radial nerve, median nerve, and ulnar nerve, all of which are responsible for the sensory functions of the skin and the autonomic nervous system.

[0043] The first stimulating electrode 10 is positioned to correspond to the surface area of ​​the radial nerve in the wrist, the second stimulating electrode 20 is positioned to correspond to the surface area of ​​the median nerve in the wrist, and the third stimulating electrode 30 is positioned to correspond to the surface area of ​​the ulnar nerve in the wrist.

[0044] The radial nerve's surface location includes the Lieque acupoint, the median nerve's surface location includes the Daling acupoint, and the ulnar nerve's surface location includes the Shenmen acupoint. The first stimulating electrode 10 simply needs to be applied to the corresponding surface location of the radial nerve; the second and third stimulating electrodes work similarly, all stimulating the corresponding nerves through pulse signals emitted by the electrodes. Preferably, the first stimulating electrode 10 is applied to the Lieque acupoint. Preferably, the second stimulating electrode 20 is applied to the Daling acupoint. Preferably, the third stimulating electrode 30 is applied to the Shenmen acupoint.

[0045] The main controller 40 is connected to the pulse generator 50, and the pulse generator 50 is connected to the first stimulation electrode 10, the second stimulation electrode 20, and the third stimulation electrode 30 respectively.

[0046] The pulse generator 50 is used to generate specific pulse signals under the control of the main controller 40, and the specific pulse signals are transmitted to the first, second and third stimulation electrodes.

[0047] The first stimulating electrode emits a pulse signal to the surface of the radial nerve. The second stimulating electrode emits the same pulse signal to the surface of the median nerve. The third stimulating electrode emits the same pulse signal to the surface of the ulnar nerve. The nerve signals are transmitted through the nerve trunk and spinal cord to the thoracic sympathetic nerves, stimulating the release of corresponding neurotransmitters in the brain and spinal cord, thereby inhibiting thoracic sympathetic nerve excitation. The thoracic sympathetic nerves then transmit the inhibitory signal to the sweat glands in the palms, inhibiting their secretion and thus eliminating the symptoms of palmar hyperhidrosis. The pulse signal uses an amplitude-modulated wave. Considering the effective energy and safety of the patient, the usable pulse frequency range is 10-200Hz, the usable amplitude range is 0.1-5.3s, and the usable current intensity range is 0.1-3.9mA. Typically, the pulse signal stimulation needs to last for 15-30 minutes to produce a therapeutic effect.

[0048] The pulse signal can specifically be a positive and negative symmetrical square wave; more specifically, each pulse of the pulse signal is a positive and negative symmetrical square wave (e.g., ...). Figure 5A (as shown), or, adjacent pulses in the pulse signal are positive and negative symmetrical (e.g. Figure 5B (As shown).

[0049] The pulse generator 50 generates identical pulse signals for the first, second, and third stimulation electrodes. Because the three stimulation electrodes receive the same signal, the stimulation intensity of each electrode is exactly the same, eliminating asymmetry in stimulation intensity and electrode polarization, thus ensuring that no electric shock accident occurs.

[0050] for Figure 5BThe pulse signal shown has doubled energy and a stronger stimulation effect per unit time because each pulse has a symmetrical positive and negative waveform. For example... Figure 4 As shown, the smartwatch 100 also includes an environmental information sensor 70 for collecting environmental and motion information, and / or a physiological parameter acquisition device 60. The environmental information sensor includes a temperature sensor, a humidity sensor, an accelerometer, and / or a gyroscope, and the physiological parameter acquisition device includes a heart rate sensor, a blood pressure acquisition device, and / or a body temperature measuring device.

[0051] The smartwatch 100 also includes a storage unit 90 for storing pulse signal triggering schemes. The main controller 40 triggers the pulse generator to generate or stop generating the pulse signal based on environmental information, motion information, and / or physiological parameters. The main controller 40 can also trigger the pulse generator to generate or stop generating the pulse signal according to a preset scheme. The preset scheme can be timed triggering / off.

[0052] The smartwatch 100 can collect physiological information from the human body through the physiological parameter acquisition device 60, and select and execute treatment plans based on this information. For example, it can determine whether a person has woken up or entered sleep by measuring heart rate, blood pressure, and body temperature. This transition in sleep state is a crucial point in the diagnosis of hyperhidrosis. The storage unit 90 stores pulse triggering schemes corresponding to the transition in sleep state based on heart rate. For example, when the main controller determines that the person has woken up based on the data collected by the physiological parameter acquisition device, it triggers the pulse generator 50 to generate pulse signals according to the pulse triggering scheme. The three stimulation electrodes continuously emit pulse signals for 15 minutes and then automatically stop. After a 15-minute interval, the pulse signals can be emitted again for another 15 minutes before stopping. When the main controller determines that the person has entered sleep based on the data collected by the physiological parameter acquisition device, it controls the pulse generator 50 to stop generating pulse signals. Other triggering schemes are also within the scope of this utility model.

[0053] The smartwatch 100 can collect environmental or motion information through the current time and the environmental information sensor 70. For example, it can determine the environment and movement mode of the human body through temperature sensor, humidity sensor, accelerometer or gyroscope, and then determine the degree of sweating. The main controller adaptively and dynamically adjusts the parameters of the pulse signal according to the pulse triggering scheme to control the stimulation time.

[0054] In one embodiment, when the heart rate reaches 81 beats / min and the blood pressure reaches approximately 130 / 70 mmHg, the stimulation time is adjusted to be more than 30 minutes. Figure 4As shown, the smartwatch 100 also includes a wireless communication module 80, which can be a 5G module, to connect with a remote medical platform. This module can transmit information collected by the physiological parameter acquisition device 60 and the environmental information sensor 70, as well as image information captured by the smartwatch 100 and text information sent by the smartwatch 100, to the remote medical platform at any time. The server of the remote medical platform or remotely connected medical personnel can then issue remote medical control commands based on the patient's condition. The smartwatch 100 receives the remote medical control commands through the wireless communication module, and the main controller triggers the pulse generator 50 to generate the pulse signal based on the remote medical control commands.

[0055] The following describes some application examples of this utility model.

[0056] Patient 1, Mr. Zhang, male, 29 years old, was clinically diagnosed with primary palmar hyperhidrosis, moderate, characterized by scattered beads of sweat on both hands. After wearing the smartwatch of this invention and receiving electrical stimulation for 5 minutes, the sweating began to decrease. After 15 minutes, the sweating disappeared. After discontinuing the use of the smartwatch, the hands remained sweat-free for 60 minutes.

[0057] In clinical practice, maintaining anhidrosis for 60 minutes after nerve stimulation is terminated is considered clinically effective.

[0058] This invention shows good therapeutic effects on various types of primary palmar hyperhidrosis, has clinical effectiveness, and is designed in the form of a watch, which is integrated into daily life and makes the treatment process difficult to detect, thus protecting patient privacy.

[0059] This invention relates to a smartwatch that provides non-invasive, accompanying intelligent treatment for the regulation of the thoracic sympathetic nerves in a convenient and effective manner. It eliminates the need for surgery, avoids severing or damaging the thoracic sympathetic nerves, and carries no adverse drug reactions or risks associated with general anesthesia. It offers excellent and safe efficacy in treating primary palmar hyperhidrosis, avoiding serious complications such as postoperative compensatory hyperhidrosis and desympatheticization. The treatment is safe, effective, sustainable, repeatable, and reduces treatment costs. Since the severity of symptoms in primary palmar hyperhidrosis varies throughout the day, this smartwatch can adaptively adjust various parameters and stimulation times of the control pulses according to different time periods, achieving intelligent regulation of the thoracic sympathetic nerves, maintaining normal skin moisture levels in the palms, and avoiding the side effect of excessive dryness. This smartwatch can achieve continuous cutaneous nerve electrical stimulation regulation, allowing for long-term treatment, maintaining therapeutic effects, and automatically assessing the patient's condition to terminate the treatment.

[0060] The above embodiments are only used to describe the technical solution of this utility model and are not to be regarded as a limitation of this utility model.
