Single-use arteriovenous puncture needle

Features and Advantages:

I. Needle Tip

1. Australia-China’s unique needle-tip manufacturing process and innovative silicone‑oil coating technology ensure smooth, painless puncture.

2. The ultra-thin needle wall design ensures exceptional toughness while enabling higher blood flow and reducing bleeding during puncture.

II. Back Hole

1. Compared with traditional back holes, Aohua’s unique elliptical back-hole design offers numerous advantages. During puncture, it minimizes damage to surrounding tissues and the fistula, thereby reducing the risk of fistula injury. The forward‑positioned back hole further reduces the likelihood of blood seepage.

III. Winglets include fixed winglets and rotating winglets.

1. The winged tip features optimal softness and an anti-slip design, ensuring a secure grip and improved control over the needle tip.

2. The locking mechanism on the wing ensures secure control and prevents unintended rotation during the puncture process.

3. The rotating wing facilitates accurate positioning of the needle tip during puncture; determine the blade orientation by referencing the black dot marked on the needle hub.

IV. Detail Design

1. The unique design at the junction of the needle tip and the winglets reduces blood flow resistance.

2. The tubing is flexible and resistant to kinking, allowing for selection of different lengths based on the treatment protocol and the patient’s specific needs; currently available lengths are 300 mm and 150 mm.

3. The integrated clamp design facilitates simple, secure opening and closing. Its double-sided anti-slip surface ensures stable, effortless operation for healthcare professionals. Standard clamps are transparent; however, they can also be customized in red or blue upon request—red clamps are designated for arterial puncture needles and connect to arterial lines, while blue clamps are for venous puncture needles and connect to venous lines.

4. The double‑wing‑plate connection design ensures a secure pipeline attachment.

5. The large threaded rear cap facilitates handling by medical personnel. Its unique threaded design complies with international standards and ensures a secure, tight connection with tubing from various manufacturers.
