Abstract

PURPOSE: To enable the preventing and reducing of the degree of hardening as generated at a part subjected to intramuscular injection by connecting one terminal of a low frequency power source to an injection needle or the like while the other terminal is connected to a specified electrode electrically to bring the electrode into contact with the skin of a patient. CONSTITUTION: One output terminal 11 of a low frequency power source 10 is connected to an injection needle 21 by an injection side connection wire 30 while the other output terminal 12 is connected to an electrode 40 by an electrode side connection wire 50. The electrode 40 is stuck on an arm or the like of a patient and the injection needle 21 is punctured into the body of the patient and an injection liquid 22 in the injector 20 is injected through the injection needle 21. During the injection, a voltage of the low frequency power source 10 is applied to the body of the patient through the injection liquid 22. Thus, during the injection of the injection liquid, a low frequency type voltage supplied causes an infiltration into a part subject to intramuscular injection and helps absorption and infiltration of a medical liquid thereby allowing a lowering of the degree of hardening.

2. Description of the Related Art There are various injections such as intramuscular injection, hypodermic injection, and intravenous injection that are used as the basis of clinical treatment injection to put a drug in the body, and intramuscular injection has a highly stimulating drug solution and high specific gravity. Chemicals or highly concentrated chemicals may be used. As the material, various kinds of admixtures having emulsions, oils, or other substances having high specific gravity are used, and the effects are often those for the purpose of sustaining and eliminating the effects.

[0003]

Generally, intramuscular injection is
Since the drug is generally a drug that has strong irritation locally at the injection site, even after the end of the intramuscular injection, the injected site becomes partially hard, and a so-called "induration" inflammation occurs, which causes a partial fever. In some cases, so-called "muscle induration" in which the muscle fascia is hardened (causing induration) occurs, often resulting in sequelae.

It is an object of the present invention to provide an injection device and an injection method capable of preventing and reducing the degree of induration that occurs in the intramuscularly injected portion.
