A Blunt Cannula Manufacturer Serving Aesthetic Brands and Clinics’ Suppliers
Zhenjiang Gaoguan Medical Appliances Co., Ltd is a blunt cannula manufacturer with 20 years of single-use medical device manufacturing experience, ISO 13485 certification, CE marked products, and exports to 30+ countries. We produce blunt-tip microcannulas for aesthetic injection procedures — plus matched sharp needles and PDO thread lifting needles — under OEM and private label terms.
Aesthetic brands live or die on practitioner experience: how the cannula glides, whether the tip is consistent from batch to batch, and whether the packaging survives shipping and looks like the brand on the box. Those are manufacturing characteristics, not marketing ones — and they are exactly what our grinding, tubing, and packaging controls are built to hold. For the technique context your practitioners will ask about, see our blunt cannula injection techniques guide.
Gauge and Length Matrix
Our standard blunt cannula platform covers the combinations aesthetic practitioners most commonly request:
| Jauge | Lengths Available (confirmed with our regulatory team) | Typical Application Area |
|---|---|---|
| 18G | 25–70 mm typical; custom lengths on request | Larger-volume facial areas per facial zone and treatment volume |
| 19G | 100L (AN-W19G-100L) | Facial volumization |
| 20G | 25–70 mm typical; custom lengths on request | Mid-face, jawline |
| 21G | 25–70 mm typical; custom lengths on request | Mid-face |
| 22G | 25–70 mm typical; custom lengths on request | Tear trough, nasolabial |
| 23G | Standard and L (long) versions | Nasolabial, lips |
| 24G | 25–70 mm typical; custom lengths on request | Fine area work |
| 25G | 25–70 mm typical; custom lengths on request | Tear trough, perioral |
| 27G | 25–70 mm typical; custom lengths on request | Superficial lines |
| 30G | 25–70 mm typical; custom lengths on request | Fine/superficial work |
Combinations outside the matrix are feasible subject to tubing availability — our tubing is sourced to defined dimensional tolerances (see medical needle tubing tolerances) and material grades (tubing material selection).
Tip and Cannula Customization Options
| Fonctionnalité | Options | OEM Notes |
|---|---|---|
| Tip type | Blunt closed tip (microcannula geometry) | Tip geometry validated per configuration |
| Wall type | Regular wall or thin wall per ISO 9626 | Thin wall increases lumen at same gauge |
| Hub | Standard luer hub; custom colors per mold | Color coding helps clinics sort SKUs |
| Handle/fit | Laser or printed depth markings | Practitioners rely on depth markings |
| Conditionnement | Individual sterile blister/peel pack; bulk packs; private-label boxes | Print artwork per your brand |
| Matched introducer needle | Introducer needle supplied with each cannula | Standard practice for entry point |
| Stérilisation | EO or gamma sterilization per product validation | Validated cycle, batch records |
Aesthetic Compliance: Watch Your Marketing Claims
This matters more than most new aesthetic brands expect. Medical device advertising rules — including EU MDR and equivalent national regimes — restrict what you can claim about injectable products. Practical guidance for our OEM partners:
- Sell the device (gauge, length, tip design, sterility), not clinical outcomes
- Avoid absolute or exaggerated claims (the “painless” and “100% safe” style of wording is both misleading and non-compliant)
- Claims about filler compatibility and procedure results belong to the injectable’s marketing authorization holder, not the cannula brand
- Keep your IFU aligned with what the cannula is actually cleared/marked for in your market
We will flag obvious compliance problems in your artwork review, but final marketing responsibility sits with the brand owner — build your claims checklist with your regulatory advisor.
Batch Consistency: What We Control
Practitioners notice when a new carton feels different. Our controls for that: tubing dimensional verification per ISO 9626 at incoming; tip geometry inspection under magnification at grinding;per applicable ISO standards (ISO 7864, ISO 9626); batch-level pull-force and dimensional sampling. Batch documentation ships with every order so your QA team can trace any lot.
