21G Safety Multi Vacuum Pen Type Needle

One session one session:
"Pen-type needle 21G" (21G Pen needle) has the following features:

In terms of appearance and structure, it is similar to the shape of a pen, which is convenient for hand-held operation. This design allows the user to better control the injection process, just like holding a pen to control the force and Angle more easily.

In terms of specifications, 21G represents the thickness of the needle. 21G needle is relatively thin, its outer diameter is small, and the damage to the tissue is relatively small during the puncture process, which can reduce the discomfort and pain of the patient.

From the point of view of use, it is mainly used for the injection of various drugs, commonly seen in insulin injection. Because insulin needs to be injected over a long period of time and frequently under the skin, the 21G pen needle allows the patient to inject insulin into the subcutaneous tissue more accurately when injecting himself, and the smaller needle helps to improve patient acceptance and make the injection process more comfortable.

One session one session:
• 21G pen needle

• Suitable for injection of slightly viscous drugs, such as some oil drugs. Because the inner diameter of the 21G pen needle is relatively wide, the viscous drug is easier to pass through, which can ensure a smoother injection process.

• It can also be used when a quick injection of medication is needed. For example, when injecting first-aid drugs such as epinephrine in an emergency, a thicker needle can make the drug enter the body in a large amount of time and play its effect.

• 23G pen needle

• Commonly used for common subcutaneous injections, such as insulin. Because insulin and other drugs do not need rapid injection, and 23G pen needle is thinner, less damage to the skin and subcutaneous tissue, can reduce the pain during injection, suitable for long-term, frequent injection.

• For some stimulant drugs, the smaller 23G pen needle causes small wounds during the puncture process, which can reduce the stimulation of the drug to the surrounding tissue.
