Precautions for Using the Injection Pen

With continuous advancements in medical technology, the Injection Pen has become a trusted drug delivery tool for pharmaceutical companies due to its advantages such as precise dosing, ease of assembly, multi-drug compatibility, and customizable features. However, to ensure its safety and effectiveness, the following key precautions should be observed when using the Injection Pen.

1.Preparation and Inspection Before Use

Carefully Read the Instructions

Different brands and types of Injection Pens may have variations in operation methods, dosage adjustment, and other factors. Before use, it is essential to carefully read the product manual to understand the specific steps for use, precautions, and how to handle any potential issues. If there are any doubts, it is important to consult a doctor or healthcare professional.

Inspect the Product Appearance

Check whether the packaging of the Injection Pen is intact, and ensure there are no damages or deformation. Also, inspect the Injection Pen for any cracks, leakage, or defects. If any abnormalities are found in the packaging or the pen itself, do not use it. Instead, immediately contact the supplier or pharmaceutical company for a replacement.

Verify Medication Information

Confirm that the medication inside the Injection Pen matches the doctor’s prescription, including the drug name, dosage, and expiration date. Carefully inspect the appearance of the medication; if it has changed color, become cloudy, or has precipitates, the medication may have deteriorated and should not be used.

2. Key Points During the Injection Process

Correct Installation and Air Purging

Follow the instructions to correctly install the needle on the Injection Pen, ensuring that it is securely attached. Before the first use or when changing to a new needle, it is necessary to purge the air from the pen to avoid injecting air into the body, which could affect the efficacy or cause safety issues. When purging air, strictly follow the operational steps to ensure that the correct amount of medication is expelled.

Accurate Dose Adjustment

The Injection Pen is designed for precise drug delivery, but users must adjust the dosage correctly. Turn the dosage adjustment knob slowly and steadily to avoid forcing it, which may result in inaccurate dosing. The black and white design of the dose values makes it easier to read, but for patients with visual impairments, assistive tools or help from another person may be necessary for adjusting the dose. Additionally, the design of audible clicks and tactile feedback during dose adjustment and injection provides added convenience for visually impaired patients, but the dosage should still be confirmed carefully.

Master Injection Site and Technique

Choose an appropriate injection site, such as the abdomen, outer thigh, or outer arm. The injection sites should be rotated to avoid injecting repeatedly in the same area, which could reduce the risk of subcutaneous fat accumulation, hardening, or other adverse effects. Before injecting, ensure that the skin is clean and dry. Disinfect the injection site with an alcohol swab and allow the alcohol to evaporate. Inject the needle at the correct angle and depth, press the injection button, and ensure that the full dose is delivered. The design and materials of the Injection Pen help reduce injection pressure, alleviating discomfort, but it is still important to stay relaxed to avoid muscle contraction, which could interfere with the injection process.

Listen and Feel for Feedback

During the use of the Injection Pen, it provides clear auditory and tactile feedback, which helps boost the patient's confidence. Pay attention to these feedback signals during both the dose adjustment and injection process to ensure that the operation is correct. If the expected sound or tactile feedback is not felt, stop the operation immediately, check the pen for any malfunction, and seek advice from a healthcare professional if needed.

3. Post-Use Handling and Storage

After use, the Injection Pen is considered medical waste and should be disposed of according to the relevant regulations. Do not discard it casually to avoid environmental pollution or harm to others. The used pen should be placed in a designated medical waste container and handed over to a professional medical waste disposal service.

In conclusion, the Injection Pen offers patients a convenient and precise method for drug delivery. However, it is crucial to follow the precautions outlined above during its use to ensure safe and effective medication administration. Only through correct usage and maintenance can the full benefits of the Injection Pen be realized, safeguarding the health of patients.
