I.V. Cannula

The injection adapter type is equipped with an independent self-sealing side injection port on the straight hub, with no fixing wings attached. This structure allows secondary medication injection without removing the primary infusion line.

Medical workers can inject medicine, draw blood or deliver emergency bolus without disconnecting the primary infusion tube, which greatly improves efficiency for frequent medication delivery.

The straight hub allows easy single-hand holding during venipuncture, making it ideal for emergency departments and operating rooms.

The winged cannula, also known as the butterfly-type, comes with a pair of flexible butterfly small wings on both sides of the hub. The wings expand the sticking area on skin, firmly securing the catheter to prevent slippage or dislodgement during long-time indwelling.

Operators can grip the two wings for steadier needle insertion, especially suitable for infants, elderly patients and those with tiny fragile blood vessels.

The pen type cannula boasts a slim, smooth pen-shaped hub without side injection ports or fixing wings. Its streamlined body leaves minimal bulge under dressing, bringing outstanding comfort for patients with active limbs, allows easy handling and fast venous access, making it suitable for routine hospital infusion and adult patients with stable veins.

It is efficient and cost-effective, but offers limited stabilization compared to winged designs.Featuring a simple structure and cost-effective price, it only allows medication administration via the main infusion line. It is mostly used for short-time outpatient infusion and routine blood collection.
