Description

Technical Field

[0001] The invention relates to the technical field of medical supplies, and more particularly to a disposable energy therapeutic patch for pain. Background Art

[0002] The treatment of chronic pain has always been a difficult problem in the medical field. As people age, they face more and more pain problems. There are more than 250 million people over the age of 60 in China, and 50% to 75% of the elderly suffer from chronic pain. More than half of them live in pain from various diseases all year round. Common pain in the elderly includes musculoskeletal pain, pain caused by diabetic neuropathy, head / maxillofacial pain, and herpes zoster-related pain. It seriously affects the quality of life of the elderly, often leading to reduced daily physical activity, decreased balance function, physical weakness, cognitive dysfunction and a high risk of falling.

[0003] Traditional solutions usually rely on opioids or invasive surgery, which is not only risky but also expensive. In the "Chinese Expert Consensus on the Management of Chronic Musculoskeletal Pain in the Elderly (2023)", electrical stimulation (TENS) can significantly reduce the degree of chronic musculoskeletal pain through effective, safe, and gradual rehabilitation exercises, and is beneficial for improving muscle strength and bone quality. However, traditional electrical stimulation equipment is too large, complicated to operate, and has complex components, which is inconvenient for operators to use. Summary of the invention

The current feedback circuit is connected to the micro control unit to form a feedback loop.

[0008] As a further solution of the present invention: the frequency of the electrical stimulation chip is generally 1-150 Hz, the pulse width is 0.04-0.5 ms, and the electrode impedance is not greater than 1 kΩ.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-2 , a disposable energy therapy patch for pain, which integrates an electric stimulation chip 2, a control circuit board 3, a button battery 4, etc. into an electrode patch 1 to form a disposable energy therapy patch for pain. The electrode patch 1 is made of medical silicone, which has good biocompatibility and air permeability. The button battery 4 is a lithium manganese battery, which has the characteristics of small size and high energy density. The disposable energy therapy patch is used to provide pain treatment through transcutaneous electrical nerve stimulation therapy, which is a non-destructive treatment method mainly for the treatment of pain. It is an electrotherapy method that inputs a specific low-frequency pulse current into the human body through the skin to treat pain. A continuous, balanced bidirectional waveform is generated by the device, generally a deformed square wave. The frequency is generally 1 to 150 Hz, the pulse width is adjustable from 0.04 to 0.5 ms, and the electrode impedance range is not more than 1 kΩ, Figure 4 It is a basic waveform diagram of the present invention.

[0025] like Figure 3 As shown, the control circuit board 3 includes a pulse output control circuit, a micro control unit, a boost circuit, a stimulation circuit and a current feedback circuit. The micro control unit is respectively connected to the pulse output control circuit, the boost circuit and the current feedback circuit. The boost circuit is connected to the stimulation circuit. The stimulation circuit is connected to the electrodes / electric needles in the electric stimulation chip 2 and acts on the human body through the electrodes / electric needles. The current feedback circuit is connected to the micro control unit to form a feedback loop.

[0026] Disposable energy therapy patch, including multiple treatment modes: traditional mode, acupuncture mode, pulse mode and modulation mode. Multiple treatment modes are preset in the micro control unit.

[0027] Among them, the traditional mode: higher frequency: 50-100Hz, low intensity; short wave width: 30-75μsec subjective feeling: anesthesia, tingling; application: usually used for acute pain.

[0028] Acupuncture mode: lower frequency: 1-10Hz, wider wave width (150-500μsec) electroacupuncture type Subjective feeling: rhythmic pulsation, usually used for chronic dull pain.

[0029] Burst Mode (Train): 2-4Hz or pulsed, with high-frequency (70-100Hz) stimulation between pulse segments. Subjective feeling: The feeling that the muscles are about to contract; mainly used for deep chronic pain.

[0030] Brief and intense mode: high frequency: 100-150Hz, high intensity: maximum tolerable current, pulse width: 150-250μsec Subjective feeling: the strongest feeling; Applicable symptoms: rapid and deep paralysis, applicable time is less than 15min.

[0031] Modulation mode: Pulse frequency and / or pulse duration fluctuating between 40%-100% of the preset value. Fluctuation period: 0.5-1.5sec, fluctuation characteristics depend on the model. Subjective feeling: increasing comfort. Scope of application: patients who are applying TENS for the first time, pain desensitization therapy. Figure 5 It is a schematic diagram of the modulation waveform of the present invention.

[0032] Mechanism of action: (1) Immediate analgesia: Immediate analgesia is the analgesia produced during and within minutes to hours after electrotherapy. Low-frequency current → excites thick (Aβ) fibers → excites glial cells in the dorsal horn of the spinal cord (SG) → gates close → pain input is weakened or blocked → analgesia. Low-frequency current → excites SG cells → γ-aminobutyric acid (GABA) neurons → releases GABA → Ca2+ channels in C fiber terminals are blocked → inhibit pain input → analgesia. Low-frequency current → endogenous pain modulation system in the higher brain centers → releases 5-HT, opioid peptides, GABA, NA and other transmitters → dorsolateral spinal cord tract → inhibits spinal dorsal horn neurons → analgesia. Low-frequency current → nerve impulse → spinal cord cortical sensory area → interferes with pain → analgesia. Low-frequency current → produces tremor and muscle tremor → excites thick fibers → pain transmission is disturbed and blocked → analgesia.

[0033] (2) Cumulative analgesic effect: The cumulative analgesic effect after multiple treatments is closely related to various factors that produce immediate analgesic effects and the improvement of local blood circulation. The improvement of local blood circulation can alleviate local ischemia and hypoxia, accelerate the clearance of pain-causing substances and acidic metabolites, reduce edema between tissues and nerve fibers, and improve local nutrient metabolism, thereby eliminating or weakening the stimulus factors of pain and achieving an analgesic effect.
