How it Works

Learn how Lenis injects without a needle

 

The Lenis is a compact injection system that delivers liquid medications or supplements by creating a narrow precise fluid stream that penetrates the skin and eliminates the need for a needle. The fine as hair liquid jet stream is produced with high pressure spring power through a micro-orifice at the end of the nozzle. This allows the medication to penetrate through the skin in a fraction of a second and deliver the fluid into the body needle-free. The Lenis system is intended to deliver between 0.1-0.5 ml of liquid medication for subcutaneous injections.

FAQs

frequently asked questions about Lenis

How should the user be prepared for injecting?

The user should be informed about the release noise of the injector to prevent defensive arm movement or startle reflex.

The injector button will not depress. What could be the cause?

In order to depress the injector button the spring of the main unit needs to be activated. To prepare the injection system for use, insert the injector into the loader with the head aligned to the sliding plunger of the loader base. Firmly push down on the loader until it closes. Open and remove injector which is now activated and ready for use.

What are the adapters for?

The adapters are for the transfer of liquid drugs from conventional medicine containers into the syringes of the needle-free Injection device. Up to now, conventional medicine containers are designed for injection by needle (cannula), e.g. pen cartridges, piercing of injection vials or snap-off ampoules. This special adapter is developed to transfer the drug from medicine containers into the syringes.

How many times can the adapter be used?

The Adapter is a disposable product intended to be used on one medication vial. Sterility is not guaranteed for multiple use, so never use the same Adapter for more than one medication vial.

How deep does the medication penetrate the skin?

The pressure and speed are calculated in such a way that the medicine only enters into the subcutaneous adipose tissue. The depth of penetration also depends on the applied volume. The 4,000 psi model penetrates 1 – 1.5 inches for doses of .5 ml and 2 inches for doses of .3 ml. The 2,000 PSI model which will be available in 2019 will have penetration under 1 inch which will be ideal for dental and cosmetic fillers.

Is changing of the injection site recommended?

Yes, the injection site should be changed in the same way as with a conventional needle.

How should the patient be positioned for injecting?

The patient should be sitting upright in a relaxed position. The time between positioning and releasing the injector should be kept as brief as possible with children and especially restless patients.

Is bleeding possible?

Bleeding does not usually occur. As with needle injections, needle-free injection device might cause some damage to the uppermost capillaries. In rare instances, this might cause a pin-sized drop of blood to appear at the needle free injection site. This is more likely to occur if the user has been taking medication to treat cardiovascular disease or normal aspirin for pain relief.

Why has some residual medication remained on the skin?

If this occurs, not all of the medication has been administered as part of it remains on the skin. Residual medicine on the skin is caused by the device not being placed firmly enough on the skin or not being applied vertically. Please ensure the next time that the injector is placed on the skin firmly and vertically. Press the injector firmly onto the injection site until the skin is clearly dented and the syringe tip is completely enclosed by the skin.

Keep the syringe pressed against the skin for 5 seconds after completing the injection.
For any other enquires please contact your seller directly.

What are the minimum and maximum quantities of medication that can be administered per application?

A minimum of 0.1 ml and a maximum of 0.5 ml of a liquid drug can be administered.

Can the syringes/nozzles be used again?

No. In order to guarantee sterility and function, the syringes are intended to be used once only.
