Backstops are special components only for glass pre-filled syringes. The backstop makes the syringe’s opening smaller and the finger flange bigger.
There are different colors and sizes of backstops for various applications. The colorful finger grips can be used as a visual signal for the user to avoid confusion.
The backstop keeps the plunger rod from coming out and makes it easier to hold onto the syringe. It is helpful, especially if the medication is thick or if there is pressure on the tissue.
Besides, the backstop helps people with difficulty holding onto things when injecting themselves.
Usually, backstops are made of polypropylene and are clipped onto the finger flange of the glass prefilled syringe. It is compatible with both round and cut syringe barrel shapes.
Prefilled syringes are a vital part of the healthcare industry, and the backstop plays an essential role after the fill and finish process.
The backstops help to ensure that prefilled syringes are of the highest quality possible.
