Proper use and maintenance of medical devices are essential for ensuring accuracy, safety, and long-term performance. The reusable injection pen by Hangzhou Sunrise Medical is designed to deliver precise doses of medication consistently, but its effectiveness depends on how well it is used and maintained. This guide will take you through the correct steps for using and cleaning your reusable injection pen, ensuring it remains reliable for long-term therapeutic applications.
When it comes to drug delivery systems, particularly those used for chronic conditions like diabetes or hormone replacement therapy, accuracy, safety, and performance are paramount. A reusable injection pen ensures that patients receive the correct dose of their medication each time, which is vital for managing conditions effectively. Improper use or failure to clean and maintain the device properly can lead to inaccuracies in dosage, potential health risks, and a shortened lifespan for the pen.
At Hangzhou Sunrise Medical, we understand that every injection counts. This is why our reusable injection pens are designed with precision-crafted components and advanced dose adjustment mechanisms, guaranteeing that each administration is accurate and consistent. Whether you're using the pen for insulin, peptide therapy, or hormone treatments, following the correct procedure for use and maintenance is crucial for your health and well-being.
The first step to ensure that your reusable injection pen works optimally is proper preparation before each use. This involves loading the cartridge and ensuring the needle is correctly attached.
The reusable injection pen operates with a replaceable cartridge, which contains the medication. Here's how you prepare it for use:
Check Medication Compatibility: Ensure the medication you're using is compatible with the pen. Our pens support 3ml cartridges, which can accommodate various medications, including insulin, GLP-1, and peptide solutions.
Insert the Cartridge: Remove the protective cap from the cartridge. Place the cartridge into the pen's cartridge holder, ensuring it fits securely. Make sure the cartridge is not damaged or expired.
Check for Air Bubbles: Before administering the injection, it’s essential to check for any air bubbles inside the cartridge. To do this, hold the pen upright and gently tap the side to move the air bubbles to the top. Dispense a small amount of medication to eliminate any air in the cartridge.
Once the cartridge is properly loaded, the next step is to attach the needle:
Choose the Right Needle: Our reusable injection pens are compatible with 29G to 32G needles. Choose the needle that fits your treatment needs and is appropriate for the medication you are injecting.
Attach the Needle: Remove the protective cover from the needle. Attach the needle to the pen by aligning the Luer-lock connector with the pen’s needle interface and twisting it into place until it is securely connected.
Prime the Needle: Before the first use or when switching needles, prime the pen by turning the dial to a small dose setting (typically 1-2 units) and pressing the injection button until a drop of medication appears at the needle tip. This ensures that the needle is fully primed and ready for use.
With the pen now ready, the next step is administering the medication. Proper technique is critical for both accuracy and patient comfort.
Turn the Dose Dial: Use the dose adjustment mechanism to set the correct dose. The reusable injection pen provides precise dosing increments, typically ranging from 0.01ml to 0.0125ml per click, allowing for accurate adjustments based on your treatment needs.
Check the Dose Window: Ensure the dose window shows the correct amount. If it doesn’t, adjust the dial until the desired dose appears in the window.
Confirm Dose Accuracy: Once the correct dose is set, ensure the dial has no resistance when turning and that it is calibrated properly.
Choose the Injection Site: Select the appropriate site for the injection. Common areas include the abdomen, thigh, or upper arm. Rotate sites to avoid tissue damage and improve absorption.
Administer the Injection: Hold the pen firmly against the skin and press the injection button. Ensure the needle is fully inserted before activating the pen to ensure proper delivery.
Hold for a Few Seconds: After injecting, hold the needle in place for several seconds to allow the medication to fully be absorbed into the tissue.
Dispose of the Needle Properly: Once the injection is complete, carefully remove the needle and dispose of it in a sharps container.
To ensure the longevity and accuracy of your reusable injection pen, regular cleaning and maintenance are necessary. Below is a table of steps that will guide you through the process.
Step | Action | Frequency |
After each use | Remove needle & wipe exterior | Every day |
Weekly | Deep clean housing | Once/week |
Monthly | Functional check | Monthly |
Do wipe the pen’s exterior with a clean cloth after each use. Use medical-grade disinfectants that are safe for plastic and metal parts.
Do inspect the pen for any signs of wear and tear. Replace the pen or parts (such as the cartridge holder or the dosing mechanism) if necessary.
Don’t submerge the pen in water or disinfectants. Only clean the exterior and remove the cartridge before cleaning.
Don’t use harsh chemicals or abrasive materials for cleaning, as they may damage the pen’s components.
Maintaining proper hygiene and safety during the cleaning process is vital for preventing contamination and ensuring that the pen remains in good working condition. Always ensure that the pen is cleaned in a sterile environment and that the cartridge is handled with clean hands.
Despite regular maintenance, there are a few common issues that users may encounter with their reusable injection pens. Here’s how to troubleshoot them:
If the dose adjustment dial feels stiff or difficult to turn, it may indicate a mechanical issue. Check for any debris or blockage in the pen’s internal mechanism. If cleaning doesn’t resolve the issue, contact customer support for assistance or consider replacing the pen.
Occasionally, the pen may leak or become blocked due to improper handling or issues with the cartridge. Make sure the cartridge is securely inserted and there is no air trapped inside. If the issue persists, ensure that the needle is correctly attached and the dose is being administered as expected.
The proper use and maintenance of your reusable injection pen are essential for ensuring its longevity and optimal performance. By following the step-by-step guidelines outlined above—such as correctly preparing the pen, administering injections with precision, and regularly cleaning the device—you can ensure consistent, accurate medication delivery. The reusable injection pen by Hangzhou Sunrise Medical is engineered for durability and reliability, providing patients with a cost-effective, sustainable solution for managing their treatments.
