Introduction to pen injectors:

The pen injector is a medical device for the purpose of injecting drugs by pushing the drugs through a manual pump, and its shape is similar to that of a commonly used ballpoint pen, hence its name. It is mainly composed of pen tip, casing, push rod, spring and adjustment structure.

1. nib: used to insert into the drug packaging tube, play a role in connection. 

2. Casing: Used to hold the injector piston rod and play a protective role. 

3. Pusher: used to push the piston rod manually to make the drug enter into the injector.

4. Spring: Used to push the piston rod, so that the drug can enter the injector.

5. adjustment structure: used to adjust the dose of drug in the injector.

The pen injector is used as follows:

1. Open the package and remove the pen injector.

2. Confirm that the package is within the shelf life and check if the pen injector is damaged.

3. Confirm the name and dosage of the drug to be injected.

4. Insert the tip of the pen injector into the medication packaging tube.

5. Place the cannula over the piston rod.

6. Push the piston rod to push the medication into the syringe.

7. Adjust the adjustment structure to determine the drug dose.

8. After confirming that the drug dose is correct, the injection can be performed.

9. Pull out the pen injector and inject the drug into the body.

10. After use, return the pen injector to its case.

Classification of pen injectors:

According to the shape characteristics of pen injectors, they can be divided into three main types:

1. ordinary pen injector: the shape of this injector is similar to that of an ordinary ballpoint pen, relatively small in size, with adjustable length and diameter of the needle.

2. Duckbill pen injector: the head of this injector is shaped like a duck's beak, which allows it to draw up medication smoothly and inject it evenly into the human body.

3. Self-locking pen syringe: The head of this injector has a locking mechanism that allows the needle to be locked when not in use, making it easy to carry.

In addition, according to the different materials used, pen injectors can also be categorized into glass, silicone and plastic, the specific classification of the use of the scene and the object has different requirements, should be selected according to the actual needs.

12. Innovative integrated design, the needle, push rod and end cap are all molded by one mold, effectively avoiding deformation during processing.

13. Adopting medical high transparent PVC material, which can visualize the injection dose.

14. Dosage scale is accurate to 0.01ml.

15. Reusable needles, reducing the use of disposable products.

16. It can be matched with the jacket, needle and sterilization tablets provided by the use unit, which solves the problem of environmental protection.

Uses of Pen Injectors:

Pen injectors are common medical devices, mainly used for medical injections. It has the advantages of easy to use, accurate injection dosage, simple operation, etc., and is widely used in clinical medicine, nursing care, home health care and other fields.
