What is the difference between an intramuscular injection needle and a hypodermic injection needle?

There are many injection methods for different parts. For example, a suspension injection is to inject the liquid into the veins. This method absorbs quickly and achieves the effect of the medicine.

Let's talk about intramuscular injection, subcutaneous injection, and intradermal injection.

Human tissues, from the outside to the inside, are the epidermis, dermis, subcutaneous tissue, and muscle.

Intradermal injection is to infuse the liquid between the epidermis and the dermis, like penicillin skin test, which is an intradermal needle, so that the absorption is slower, even if you are allergic, you will find it in time.

Subcutaneous injection is to inject the drug solution into the subcutaneous tissue, like a vaccination is a subcutaneous injection.

Intramuscular injection, in addition to skin test, vaccination, general drugs, except those that require rapid absorption, or we require that the drug cannot be absorbed quickly, because rapid absorption will have adverse effects, usually intramuscular injection.

Intramuscular injection, the muscle injection site has the gluteus maximus, which is what we usually call the butt needle, with the gluteus medius and gluteus minimus, (usually a child hits this place because his gluteus maximus has not been fully developed to prevent damage Sciatic nerve), lateral femoral muscle injection, upper arm deltoid muscle injection.

Each has a specific selected part, not to say that it is a butt needle, that is, it can be hit anywhere on the butt, and its positioning is based on the principle of avoiding large blood vessels and nerves.

These injection methods have different purposes and injection techniques.

Intradermal injection is the smallest injection angle, and intramuscular injection is generally vertical.

Usually we administer drugs based on different absorption rates.

These injection methods are also called administration methods, and there are other methods of administration, such as intravenous (ie, suspension injection), sublingual injection, oral administration, rectal administration, and topical application.

The order of these kinds of absorption speed (that is to achieve the drug effect) from fast to slow is:

Intravenous, sublingual, inhalation, intramuscular injection, subcutaneous injection, rectal administration, oral administration, topical application.
