Xinfuda supports pharmaceutical, biotech and medical device teams evaluating a single-use, fixed-dose autoinjector with hidden-needle operation. Our current platform is designed around a 1 mL prefilled syringe.
For projects requiring another syringe capacity or a different device configuration, Xinfuda can start a joint development review based on the actual primary container, formulation and delivery requirements.
| Product type | Single-use autoinjector / automatic injection device |

| Quality system | ISO 13485 quality management support for device manufacturing and supplier review |
| Initial project inputs | PFS drawing or samples, fill volume, viscosity, needle configuration, target injection time, intended market and forecast volume |
| Development Level | Typical Scope | Project Status |
| Current platform | 1 mL PFS fit, fixed-dose activation, hidden-needle operation and current device dimensions | Current product direction |
| Commercial customization | Device color, logo, label, surface presentation, carton and instruction material | Project customization |
| Device adaptation | PFS fit, drive parameters, activation logic, injection time, needle shielding and user feedback | Engineering evaluation required |
| Other capacities | Alternative syringe capacity, housing dimensions, internal mechanism and assembly approach | Joint development project |
1. What is an autoinjector?
An autoinjector is a drug delivery device designed to automatically administer a pre-measured dose of medication. It simplifies self-injection by automating
key steps of the injection process and often incorporates safety features such as hidden needles.
2. What medications can be delivered using an autoinjector?
Autoinjectors are commonly used for:
GLP-1 receptor agonists
Insulin therapies
Biologics
Monoclonal antibodies
Growth hormones
Peptide therapies
Emergency medications such as epinephrine
3. Why are autoinjectors becoming increasingly popular?
Autoinjectors improve patient convenience, reduce injection anxiety, simplify self-administration, and support better treatment adherence. They are
particularly valuable for chronic diseases requiring long-term injectable therapy.
4. What are the advantages of autoinjectors compared to traditional syringes?
Key advantages include:
Easier self-administration
Reduced risk of dosing errors
Hidden needle options
Improved patient confidence
Enhanced treatment adherence
Greater safety during handling and disposal
5. Can autoinjectors be customized for different drugs?
Yes. Autoinjector platforms can be customized to accommodate various drug formulations, injection volumes, viscosities, needle
specifications, and user requirements.
