Terumo 21G hypodermic needle with thin-wall design
The Terumo 21G hypodermic needle is a sterile, conventional needle designed for general professional use. It combines a precision-manufactured double-bevel tip with a thin-wall design to support smooth penetration and fluid delivery.
The needle measures 21G × 1 in, equivalent to 2.54 cm, and has a green hub for quick visual identification of its gauge. Each needle is individually packaged and intended for a single procedure.
Precision-manufactured double bevel
Terumo hypodermic needles feature a double-bevel tip that is precision-ground and honed for sharpness. The carefully manufactured point is designed to facilitate penetration during appropriate professional procedures.
The regular hypodermic tip makes this needle suitable for general applications, depending on the procedure, the clinical requirements and the professional judgment of the qualified user.
Thin-wall needle construction
The Terumo 21G hypodermic needle incorporates a thin-wall cannula. A thin-wall design provides a larger internal diameter than a comparable regular-wall needle while maintaining the same external gauge.
This construction supports the movement of fluids through the needle. The appropriate needle size and wall type must always be selected according to the intended application, the fluid being handled and the procedures established by the healthcare facility.
21G × 1-inch size
This model has a gauge of 21G and a length of 1 in (2.54 cm). The dimensions are clearly identified on the box and individual packaging to help professionals select the required needle.
The hub is green, following the commonly used colour-identification system for 21-gauge needles. This visual indicator makes the gauge easier to distinguish when different needle sizes are stored together.
Compatible needle hub
The needle is designed to connect to a compatible syringe. The syringe is not included in the box and must be selected separately based on the intended professional application.
Before use, the connection between the syringe and the needle should be checked to ensure it is properly secured. Users must follow the syringe manufacturer’s compatibility requirements as well as their facility’s established procedures.
Sterile individual packaging
Every Terumo 21G hypodermic needle is supplied in its own sealed sterile package. Individual packaging helps preserve the product’s sterility until it is opened for use.
The package should be inspected before opening. The needle must not be used if the packaging is damaged, previously opened or past the indicated expiry date. The protective cap should remain in place until the needle is ready to be used.
Single-use product
This needle is a disposable medical device intended for one procedure only. It must never be reused, reprocessed or resterilized.
After use, the needle must be discarded immediately in an approved sharps container. Healthcare professionals should follow their facility’s infection-control procedures and all applicable requirements regarding the handling and disposal of sharp medical devices.
This conventional Terumo needle does not include an integrated safety shield. Appropriate handling practices must therefore be followed before, during and after use.
Box of 100 sterile needles
The Terumo® 21G × 1 in needle is sold by ConceptASR in a box of 100 individually packaged needles. A complete manufacturer’s case contains 1,000 needles, or ten boxes of 100.
The box format provides clinics, healthcare facilities and other professional environments with a practical quantity while avoiding the need to purchase a complete case.
