KT-90A Nerve Injury Treatment Instrument

- Type low-frequency therapeutic instrument neuromuscular electrical stimulation instrument
. Instrument features
. ☆ Stimulate denervated muscles through low-frequency pulse current, causing them to produce rhythmic contractions, increase muscle tension, and maintain muscle health r state, delaying muscle atrophy and promoting nerve recovery.
. ☆Meet the minimum pulse width requirement for reliable excitation of denervated muscles and ensure that both nerve-damaged muscles and muscles of children with hypotonic cerebral palsy can be excited.
. ☆Three-channel output, the frequency is continuously adjustable, the stimulation intensity is independently adjustable, and it can treat three patients or three parts at the same time.
. ☆According to the patient's condition, two levels of treatment, partial denervation and complete denervation, can be selected.
. ☆Computer timing is accurate, minutes. ． ． ． ． 3 and 6 levels, with time reporting function after treatment.
. ☆It has output blocking function. If the output adjustment potentiometer is not in place, the output cannot be started.
. ☆ Bipolar group electrical stimulation, acupoint therapy, acupuncture on partially denervated r, and electroacupuncture treatment can be performed.
. Indications
. The product can be used for partial denervation and complete nerve treatment

. ㈠Overview< br/> .
.-type (formerly: Nerve Injury Treatment Instrument) is a product jointly developed by experts in the field of rehabilitation physiotherapy in our factory as early as the end of the 1990s. It is used to treat partial denervation, complete denervation, and peripheral nerve damage. Nerve-induced limb diseases, etc. It is mainly used to electrically stimulate partially or completely denervated muscles after nerve damage. It protects and treats denervated muscles through electrical stimulation and shortens the recovery period of their motor functions.
. This instrument has been widely used by hospitals, nursing homes, maternal and child health care hospitals, and rehabilitation centers for the disabled at all levels across the country since its sales in 2015. It is mostly used for the treatment of patients with neurological injuries and children with cerebral palsy (hypotonia). . In recent years, the proportion of government procurement in product sales has increased year by year.
.
. (ii) Mechanism of therapeutic action of denervated muscles
.
. After peripheral nerve damage due to various reasons, the impulse from the brain cannot be achieved by damaging the local area. As a result, voluntary movement of the muscles to which this nerve is attached is reduced or eliminated, which may be a temporary and reversible change. The nerve returns to its innervation on its own or with treatment. After denervation, the muscles will undergo a series of adverse changes. During this period, active and effective treatment and protection measures should be taken to maintain the muscles in a normal state, prevent muscle atrophy and degeneration, and improve muscle tone. Once the innervation function is restored, the patient's voluntary movement function can quickly recover.
. ① Muscle changes after denervation:
. Muscle fibers shrink, their diameter decreases, and their water content drops rapidly.
. The muscle arteries become thickened and the meridians become congested.
. The colloid shrinks further, the diameter of muscle fibers decreases, and connective tissue proliferates.
. Vascular changes and connective tissue hyperplasia continue.
. Muscle fibers also begin to lose their continuity, and muscle fibers degenerate and die.
. ②The therapeutic effect of low-frequency pulse electrical stimulation on denervated muscles
. Improve biological activity, prevent muscle mass and damage to electrolytes, enzyme systems and contractile substances. Improve blood circulation and nutrition of muscles, retain glycogen content in muscles, and reduce muscle wasting.
. The meridians and lymphatic vessels are regularly squeezed, emptied, expanded and filled. Promote meridians and lymphatic return, improve metabolism and nutrition, and slow down the process of muscle atrophy.
. Inhibit muscle fibrosis and prevent connective tissue from thickening, shortening and hardening.
. Preserve the normal function of the connective tissue in the muscle and prevent its contracture and interfascicular aggregation.
.
.
. (IV) Multiple stimulation methods
.
. Bipolar group method: mostly used to treat individual or a small number of muscles, using two conductive electrodes of the same size Rubber sheets serve as electrodes and are placed over the patient's treatment area.
. Single-stage group method: When used for small muscles or when multiple muscles need to be stimulated in one treatment, written electrodes are used. One small pen-shaped electrode is used on the target muscle, and the other larger electrode is placed on the target muscle. on nearby skin.
.
. (5) Treatment site and treatment course
.
. Treatment site: Select the denervated muscle as the target muscle (in case of uncertainty, select the target muscle for electrical stimulation) The reaction is the muscle that helps complete these voluntary movements) and the electrodes are placed on both ends of this muscle for treatment.
. Treatment course: partial degeneration or partial denervation takes about ~ weeks, complete degeneration or complete denervation takes about ~ months. Electrodiagnosis can help predict the trend of nerve recovery and regeneration and determine the final treatment time.
.
. ㈥Selection of parameters
.
. Frequency of current: The frequency of current is the number of pulses per second, that is, the number of stimulations per second, expressed. Occurs per second. Occurs per second. Usually the treatment area is large and the frequency of selection is less. Under the treatment area, the frequency of selection is higher. The frequency of selecting severe parts can be lower, and the frequency of mild parts can be higher.
. Pulse width: The pulse width is the residence time of a pulse on the patient in one cycle, in units of . All other things being equal, the wider the pulse width, the more intense the stimulation the patient will feel.
. Output current intensity: Current intensity is generally the amount of electricity flowing per unit. The current intensity output by this therapeutic device refers to the current intensity of each pulse. During treatment, the current intensity should be selected to cause an obvious contraction response of the diseased muscles.
.
. ㈦Other applications
.
. ★When frequency is selected, the antagonist muscles of the spasmodic muscles are stimulated individually to strengthen the strength of the antagonist muscles. Through interactive inhibition, the muscles can be relieved. Spasms.
. ★Carry out low-frequency mode (acupuncture-like) at the partial denervation level. It is better to increase the current intensity enough to cause local muscle contraction in the relevant segments. The contraction may be uncomfortable, but this method has a longer pain-free duration. long. The analgesic effect appears ~3 days after treatment. ★ Partially denervated filiform needles, and carried out electroacupuncture treatment. Electric pulses were connected to the acupuncture needles instead of hand-twisted needles. The intensity of the current can cause a slight tingling, vibration or muscle beating sensation. Time ~ makes up for it. The current is large, the contraction is strong, and the time is long.
