Advantages of Disposable Pen Injector

The Rise of disposable pen injectors
Over the years, the market for diabetic care products has witnessed tremendous progress. One such breakthrough is the advent of disposable pen injectors. Previously, reusable syringes posed numerous challenges, including the risk of infection, inconvenience, and difficulty in measuring insulin accurately. Disposable pen injectors address these concerns while providing a simpler and more hygienic solution.

Convenience and Ease of Use
Disposable pen injectors offer unparalleled ease of use. Designed to be self-administered, these syringes require minimal training, making them ideal for patients of all ages. With clear measurement markings, patients can accurately measure their insulin dosage, reducing the risk of miscalculation. Additionally, the compact size and portable nature of disposable pen injectors allow individuals to carry them discreetly, enabling spontaneous injections regardless of the location.

Hygiene and Safety
Maintaining proper hygiene is crucial when it comes to managing diabetes. Sterile insulin syringe eliminates the need for cleaning and sterilization, as they come pre-packaged, ensuring complete sterility. This reduces the risk of contamination and infections, promoting better overall health for individuals relying on insulin injections.

Reduced Pain and Discomfort
Thanks to advancements in needle technology, modern disposable pen injector employs ultra-thin needles that provide a virtually painless injection experience. This is particularly beneficial for patients who require frequent insulin injections, as it minimizes discomfort and promotes adherence to the treatment regimen. The smoother injection process also helps prevent bruising and tissue damage, ultimately leading to better insulin absorption and improved patient outcomes.

Application of Disposable Pen Injector

The filling process of pharmaceutical companies

Fill the syringe barrel (with a protective cap) with a fixed amount of medicine through the filling machine, press or screw in the piston to seal the liquid, and then install a push rod for packaging. As for products without injection needles, the pharmaceutical factory will also be equipped with corresponding needles.

Injection

Take out the disposable pen injector supplied by the pharmaceutical company and remove the package to disposable pen injector. The injection method is the same as that of an ordinary syringe.

Surgical irrigation

Take out the disposable pen injector supplied by the pharmaceutical company, remove the package, and install the matching flushing needle on the cone or spiral head, and then the flushing operation in the operation can be performed.

Performance Improvement of Disposable Pen Injectors

In the past two years, there has been a surge of research and development in the market for a new generation of disposable pen injectors. As most patients are reluctant to inject insulin in public, manufacturers have focused on the design of the newdisposable pen injector needles to make them slimmer and lighter, resembling a pen more closely. This helps protect the privacy of patients' medical condition and alleviate their psychological burden associated with injections. Additionally, the new pens offer greater convenience in cartridge replacement, clearer dose readings, and easier dose correction. Through mechanical improvements, injection resistance has been reduced, helping patients overcome their fear of injections. Some products have even incorporated digital technology to achieve smart dosing. The new disposable pen injectors are portable, allowing patients to carry them wherever they go. By simply pressing the automatic plunger at one end of the pen, the precise dose of insulin is delivered subcutaneously. The needle portion of this injection pen is extremely thin, resulting in virtually painless injections. With further research on injection devices, complementarydisposable pen injector needles have also made breakthroughs in terms of injection comfort and ease of use.

Compared to previous products, the current selling points of the new generationdisposable pen injector needles lie in their patient-friendly pen body design. They feature a larger dose adjustment window for clearer dose readings. The required injection force has been reduced by half, and the plunger rod can be pushed back directly, allowing for simple two-way dose adjustment. An audible reminder signals the completion of the injection, notifying patients that the process is finished. Furthermore, the pens can accurately measure the remaining dose in the cartridge, ensuring the accuracy of cartridge replacement. As for the accompanying consumable, thedisposable pen injector needles have also been optimized in terms of needle and tip design to achieve painless and precise injections. Specifications have been adjusted to cater to different user groups.

5 Precautions for Using Disposable Pen Injectors

Disposable pen injectors cannot be matched to the same needle many times

The disposable pen injector needle is a disposable product. The diameter of the needle is thin, and the needle is sharp. A thin silicon layer is applied outside to lubricate and reduce friction with the skin. The needle wall is also fragile, reducing the discomfort during injection. From a functional point of view, the needle will bend and deform with burrs or reverse grooves after multiple injections, increasing the resistance when injecting and pulling out the needle and causing damage to local tissues, resulting in injection pain ecchymosis and induration on the skin. From the perspective of safety, repeated use of needles may lead to cross-infection of blood or other infectious diseases, which has a high safety risk. Therefore, the disposable pen injector is designed to fix the needle to ensure that the syringe and needle are disposable and not reused.

Different concentrations of insulin cannot be mixed in the syringe of insulin

When using an disposable pen injector and insulin pen, pay attention to distinguish. The insulin concentration in a refill is different from that in a bottle. The insulin in a bottle is about 4ml, and the insulin in a refill is approximately 3ml. In order to avoid the wrong injection dose and prevent hypoglycemia, bottled insulin cannot be put into the refill, and the insulin in the refill cannot be extracted with an ordinary disposable pen injector.

Store insulin properly and pull out the needle of disposable pen injector after insulting injection

Insulin is a small molecule protein. The insulin that has not been unpacked needs to be stored in an environment of 2 ~ 8℃. If it exceeds 8℃, the insulin efficiency will be changed. If it is lower than 2℃, the insulin solution will lose biological activity, thus affecting the hypoglycemic effect. In addition, insulin cannot be frozen and shaken excessively, nor can it be directly exposed to the sun. The unpacked insulin shall be stored at room temperature, which shall not exceed 30℃, and whether to put it back into the refrigerator for storage shall be determined according to the instructions. Both ends of the insulin pen needle are needle tips.

Sterile operation of disposable pen injector

Because insulin injection is a subcutaneous injection, it is necessary to achieve aseptic operation strictly. Mucous membranes and skin are defense barriers, and there are many microorganisms on the surface. There is also a continuous increase in blood glucose in diabetic patients, suitable for all kinds of bacteria to grow, reproduce and cause or aggravate skin infections. So we must pay attention to disinfection. Wash your hands before injecting insulin with a safety disposable pen injector, and then disinfect the injection site with 75% alcohol. Don't wipe it back and forth. Inject insulin after the alcohol is dry.

Do not inject insulin into the muscle layer when using an disposable pen injector

Intramuscular injection of insulin will affect the body's absorption of insulin. Thus the effect of blood glucose control is poor, which is easy to cause blood glucose fluctuation. When using an disposable pen injector to inject insulin, the skin can be gently pinched up, deepening the depth of subcutaneous tissue in this part and improving the injection safety.

What Are the Sizes for Disposable Pen Injectors?

Disposable pen injectors come in multiple sizes to deliver different doses of insulin.
The number lines in an disposable pen injector, measured in milliliters (mL), stand for the following:
● 0.3 mL syringes are for insulin doses under 30 units of insulin and are numbered at 1/2-unit or 1-unit intervals.

● 0.5 mL syringes are for 30 to 50 units of insulin and are numbered at 1-unit intervals.

● 1.0 mL are for doses more than 50 units of insulin and are numbered at 2 units per interval.

● The size of the barrel determines how much insulin a syringe holds, and the needle gauge determines the needle thickness. Thinner needles may be more comfortable to inject for some people.

● The length of a needle determines how far into your skin it penetrates. Needles for insulin only need to go just under your skin and not into muscle. Shorter needles are safer to avoid going into the muscle.

What Precautions Should Be Considered Before Using Disposable Pen Injectors?

Carefully inspect the packaging of the syringe for any signs of damage or tampering. A damaged or compromised package may indicate that the device is no longer sterile or safe to use. Check the expiration date of the syringe to ensure its effectiveness and reliability. Expired units should not be used as they may have degraded or lost their sterility. Always use a new, unopened syringe to avoid any contamination risks.

How Do You Know What Size Disposable Pen Injector to Use?

Disposable pen injectors come in multiple sizes with different needle length options. The correct size depends on your insulin dose and your comfort level with the needle size. It’s important to choose the correct size to give yourself the full dose of insulin in one shot and to avoid errors in dosing from using the wrong syringe. You may need multiple syringes if you give different doses per day. For example, 35 units in the morning and 10 units at night means you need a 0.3-mL syringe and a 0.5-mL syringe for each dose. Syringes also allow more flexibility if doses need to be adjusted daily based on your blood sugar levels. If your dose is close to the maximum capacity of the syringe, you may want to go up a size to avoid problems handling the syringe.

General Guidelines for Disposal of Disposable Pen Injectors

You can destroy the syringe using a needle clipping device. Do not use scissors or other implements.

Recap needles that have not been destroyed.

Place syringes and needles in a 'sharps' disposal container. You can get these at pharmacies, medical supply companies, or online. Check with your insurer to see if the cost is covered.

If a sharps container is not available, you may be able to use a heavy-duty puncture-resistant plastic bottle (not clear) with a screw top. Used laundry detergent bottles work well. Be sure to label the container as 'sharps waste.'

Follow your local community guidelines for disposing of sharps waste.

Never throw syringes in the recycle bin or loose in the trash.

Do not flush syringes or needles down the toilet.

Sterilization Methods for Disposable Pen Injectors

Ethylene Oxide (ETO) Sterilization

Ethylene oxide gas is a commonly used sterilant for medical devices, including disposable pen injectors. This method involves placing the needles in a sealed chamber and exposing them to a controlled concentration of ETO gas. The gas penetrates the packaging and kills microorganisms through a process known as alkylation. ETO sterilization is particularly effective for heat-sensitive materials and intricate needle designs.

Gamma Irradiation

Gamma irradiation is a sterilization method that utilizes high-energy gamma rays from a radioactive source, such as cobalt-60 or cesium-137. The needles are exposed to these rays, which penetrate the packaging and disrupt the DNA of microorganisms, rendering them unable to reproduce. Gamma irradiation is widely used for single-use disposable disposable pen injectors, as it is quick, efficient, and does not leave any chemical residue.

Electron Beam (E-beam) Sterilization

E-beam sterilization involves exposing disposable pen injectors to a beam of high-energy electrons. These electrons disrupt the genetic material of microorganisms, preventing their ability to reproduce. E-beam sterilization is a rapid method that can be applied to a wide range of materials, including plastics and metals. It is particularly suitable for mass production settings due to its efficiency and scalability.

Safety Features of Disposable Pen Injectors

Needle Shields

Disposable pen injectors are equipped with needle shields that protect the needle during storage, transportation, and disposal. These shields provide an essential barrier, reducing the risk of accidental needlestick injuries and contamination.

Safety Caps

The caps found on the needle ends of disposable pen injectors provide an additional layer of protection against accidental needle pricks. These caps are designed to be easily removable and should not be replaced after injection to avoid contamination.

Clear Measurement Markings

Disposable pen injectors are marked with clear and legible measurement indicators, allowing for precise dosage measurement. This feature is crucial for individuals who require accurate insulin doses to maintain optimal blood glucose control.

Graduated Barrels

Disposable pen injectors have graduated barrels that facilitate the accurate measurement of insulin units. The precise delivery of insulin is essential for individuals who rely on specific dosages to manage their diabetes effectively.

Proper Storage of Disposable Pen Injectors

Ensure that the syringes are stored in a clean and dry environment.
Store the syringes in a protective case or container to prevent physical damage.
Keep the syringes away from direct sunlight, extreme temperatures, and humidity.
Avoid storing syringes in the bathroom, as the humidity can affect their sterility.
If using disposable pen injectors, keep them in their original packaging until ready for use.
