Pen Syringe

A pen syringe, also known as a pen injector, is a drug delivery device resembling a ballpoint pen, primarily used for subcutaneous or intramuscular injection of medication at a set dosage. It typically consists of a pen body, dosage adjustment mechanism, plunger, cartridge, disposable needle, and protective cap, and features precise dosage, ease of operation, and portability. With the increasing demand for biopharmaceuticals and self-administration, pen syringes have become one of the important packaging formats for high-end injectable formulations.

Product Features:
1. Precise Dosing: Employing a mechanical or electronic dosage adjustment system, the dosage for each injection can be precisely set, reducing human error and improving dosing accuracy.

2. Simple Operation: Users simply attach the needle, set the dosage, and press the injection button to complete the administration, suitable for long-term self-injection therapy.

3. Portable: The compact pen design facilitates transportation and portability, making it suitable for home, hospital, and mobile healthcare scenarios.

4. High Safety: The disposable needle design reduces the risk of cross-infection. Some products also feature dose locking and remaining medication display functions, improving safety.

5. Reusable or Single-Use: Depending on the product design, they can be divided into:
Reusable Pen: Simply replace the cartridge and needle for continued use.
Disposable Pen: The entire pen is discarded after the medication is used up.

Main Applications in the Chemical and Pharmaceutical Industries

While pen syringes are ultimately used in the medical field, they are primarily used as an important component of drug delivery systems in the chemical, pharmaceutical raw materials, and pharmaceutical industries.

1. Biopharmaceutical Product Support
Widely used for packaging and delivery:
GLP-1 receptor agonists
Insulin and insulin analogs
Growth hormone
Monoclonal antibodies
Peptide drugs
Hormonal preparations
In recent years, the development of GLP-1 weight loss and blood sugar lowering drugs has further driven market demand for pen syringes.

2. Pharmaceutical Cartridge Support
Pen syringes are typically used with **3 mL glass cartridges (3 ml cartridges)**. The medication is pre-filled into the cartridge and then inserted into the pen syringe for precise drug delivery.

Key supporting products include:

3ml Cartridge

Brominated butyl rubber stopper

Aluminum cap

Pen syringe body

Disposable injection needle

3. Pharmaceutical filling production lines

Pen syringe production typically involves:

Cartridge cleaning

Sterilization

Aseptic filling

Capping

Appearance inspection

Automatic assembly

Automatic packaging

Therefore, pen syringes are widely used in aseptic formulation production lines.

4. CDMO and CMO projects

More and more biopharmaceutical companies are developing pen syringes as **drug-device combination products**. CDMO/CMO companies provide integrated services from drug filling to pen assembly.

Main application industries

Biopharmaceuticals

Pharmaceutical industry

Medical device manufacturing

Pharmaceutical packaging materials

CDMO/CMO

Biotechnology companies

Hospitals and home self-medication
