A pen needle (or insulin pen needle) is an essential component for people with diabetes, used for accurate and less painful insulin injections. Choosing the right pen needle directly impacts injection comfort, insulin absorption, and the reduction of skin complications. Today, with advancements in technology, insulin pen needles are produced in various sizes and designs to meet the diverse needs of patients.
A pen needle (or “sar sozane ghalami” in Persian) is a disposable needle specifically designed for use with injector pens, such as insulin pens. Due to their delicate structure and advanced technologies, these needles make injections less painful and more accurate. Pen needles are produced in various sizes concerning length and thickness; the higher the gauge number, the thinner the needle, resulting in less pain. These needles are typically made of stainless steel and have a silicone coating to reduce friction and facilitate easier skin penetration. Some advanced models even use technologies like triple beveling and electropolishing to further minimize pain.
Pen needles are supplied sterile and must be replaced after each use to prevent infection and maintain efficiency. In terms of application, pen needles are primarily used for subcutaneous injection of medications like insulin and are compatible with most standard insulin pens. The shorter length of modern needles, such as 4 mm, reduces the risk of intramuscular injection and improves drug absorption.
Types of pen needles are as follows:
The 4 mm pen needle with a 32-gauge (32G) is one of the most advanced and practical needles designed for subcutaneous injections. It is particularly suitable for patients with thin skin or children who require shallow, painless injections. This model is designed with an extremely short length of 4 mm and an exceptionally thin diameter (32G) to cause the least amount of pain and discomfort for the patient. One of its unique features is its triple-bevel cutting technology, and the silicone coating on the needle reduces injection pain.
The 5 mm pen needle (31G) is a widely used tool for insulin injection. With a length of 5 mm and a 31-gauge, it strikes a good balance between comfort and skin penetration.
The insulin syringe with a 6 mm needle (31-gauge) is a specialized tool for diabetic patients who require deeper insulin injections. This pen needle is designed for individuals with thicker skin or those receiving higher doses of insulin. The 6 mm needle with a 31-gauge, despite its longer length, provides considerable comfort to the patient thanks to its thin design.
The 8 mm pen needle (30G) is a specialized needle designed for deeper injections. With a length of 8 mm and a thin diameter (30-gauge), it is suitable for patients with more subcutaneous fat.
Hemofine Droplet pen needles are classified as Class II medical devices according to European Union Medical Device Regulation (EU MDR) and the U.S. Food and Drug Administration (FDA) regulations. This classification is due to the direct contact of these products with the patient’s body and the need for strict quality and safety monitoring. These pen needles are designed and manufactured in compliance with international standards ISO 13485 (Quality Management Systems for Medical Devices) and ISO 11608 (Specific standard for injector pens and associated needles). Furthermore, these products have obtained the CE mark, which confirms compliance with European regulations. Hemofine Droplet pen needles are supplied sterile and for single-use to ensure the highest level of safety and hygiene for patients.
HTL-STREFA, as a reputable and leading manufacturer in the field of medical devices, focuses on state-of-the-art technologies to produce pen needles that provide accuracy, comfort, and high safety standards for diabetic patients. The design of these products not only minimizes injection pain and discomfort but also ensures accurate drug dosage. These features play a key role in improving patient adherence to treatment regimens and ultimately enhancing their quality of life.
Choosing the right pen needle plays a key role in a more comfortable insulin injection experience and effective diabetes control. By considering factors such as needle length, thickness, and pain-reducing technology, you can select a tool that both minimizes pain and optimizes insulin absorption. Diabetes requires precise management, and with appropriate tools like high-quality pen needles, this journey will become simpler and less challenging.
