Needle electrode connecting device using normal needle for myoelectricity guide injection

Abstract

A needle electrode connecting device using a normal needle for myoelectricity guide injection refers to a device and an accessory leading medium into human body in an injection mode; the needle electrode connecting device using the normal needle forelectromyogram positioning injection technology is specially provided; the needle electrode is formed by an injection needle and a spring lead wire fixing hook; the spring lead wire fixing hook comprises a metal hook with a hook-shape front end, a spring surrounding the metal hook and placed in a plastic casing, a release button connected in the end of the metal hook, and a myoelectricity signal line connected with the metal hook; the metal hook is hung on the root of the injection needle, and tightly attached to the injection needle; the myoelectricity signal line is connected with an electromyogram instrument through a myoelectricity lead wire port, thus forming a myoelectricity detection loop. The needle electrode connecting device uses the normal needle to realize accurate local muscle positioning under myoelectricity guide, and medicine can be simultaneously injected, thus reducing patient repetition puncture pain, greatly reducing medical cost, and reducing patient economical burden.

Description

technical field [0001] The invention relates to a device for introducing a medium into the body by injection and its accessories, in particular to a needle-electrode connection device for electromyography positioning injection using a common needle. Background technique [0002] EMG guidance is an important technique for botulinum toxin injections in the treatment of dystonia and other diseases. In the past, the commonly used method was to use the electromyography concentric electrodes to detect the main responsible muscles, and then use the injection needle to inject the drug. At this time, the same part of the patient needs to be punctured at least twice. The Chinese utility model patent "Myoelectric Guidance Therapy Apparatus" (Patent No.: ZL02216929.6, Authorized Announcement No.: CN2534972Y) discloses a Myoelectric Guidance Therapy Apparatus, which includes a box with a display screen and a device for communicating with the human body. The contact surface is coated wit...

Problems solved by technology

A few foreign companies have produced EMG probe needles for injection, but the single price is 350-800 yuan per piece. Although it is possible to detect EMG signals and inject drugs into the muscle abdomen at the same time, due to the high price, it is extremely expensive. Greatly increased the burden of treatment for patients
