Finally...No Needle !


Needle-Free Injections with the Comfort-In™ Kit

Nobody likes needles.  Whether you are a tough guy or a little kid.  Needle-free insulin injections are a safe and pain-free solution for people with diabetes and are simple for both adults and children to use.  With the Comfort-In™ Needle-Free Injection Device, the insulin is pushed through a micro-orifice into the superficial skin cells to the tissue below.  This is achieved by using a precise measurement of pressure at a fraction of a second without the pain and fear associated with needles. t

Discomfort or even anxiety related to regular insulin injections by needles are now a thing of the past.  Whether you are changing from an oral dose of medication to insulin therapy or have had to inject insulin several times a day for a long time, with the Comfort-In™ you can inject insulin in a tissue preserving way and avoid possible scar formation from daily needle injections.

With this reusable injector, the insulin is pushed through a micro-orifice with precisely measured pressure between the superficial skin cells into the tissue below, in a fraction of a second.  The injection is strictly subcutaneous and this method is virtually painless and without the risk of injury.  Infections resulting from needle stick injuries are likewise ruled out.

Diabetics have been using needle-free injectors in the United States for at least 20 years.  Needle-free injectors are also used in dental offices, podiatrists’ offices, ambulatory surgical centers, hospital emergency rooms and inpatient operating rooms.  Needle-free Injectors account for up to 7% of the U.S. injection market.

Fast Absorption
While needle injections leave a pool of medication, the injections from the Comfort-In™ disperse and spread the medication uniformly in a spray pattern, resulting in faster absorption.

The adapters and NOZZLES of the Comfort-In™ are sterilized with gamma irradiation and are disposable, eliminating the possibility of cross-contamination.

It's Fast, Safe and Easy
The fast, easy needle-free injection takes less than 1/3 of a second to go through the micro-orifice with the technology of the Comfort-In™ automated spring pressure.

It's Low Maintenance, With a Long Life
The Comfort-In™ needle-free injector can be used for over 10,000 injections whether in a professional or personal setting.​​

Ten (10) NOZZLES for Comfort-in™ are Included in Your Kit

The Comfort-in™ needle-free NOZZLE (also known as ampule or syringe) is a single-use syringe with a transparent body, capable of holding any dose from 0.01ml (1 unit) up to 0.5 ml (50 units) of any pharmaceutical liquid, with a plunger to discharge the medication through a micro-orifice at the tip of the NOZZLE and a rubber seal at the topmost tip of the plunger to prevent leakage and/or air bubbles while filling.  The tip of the NOZZLE in direct contact with the user’s skin: it is therefore supplied in a sterile blister pack and intended for single use only.

While this is recommended as a single use item, some individuals with diabetes chose to reuse the same NOZZLE for the whole day, after rinsing it with saline solution.

One (1) 14 mm Vial Adapter for Comfort-in™ is Included in Your Kit (see reorder note below) 

Our needle-free vial adapter with three (3) prongs is suitable for vials which have a crimped diameter of up to 14mm.  The needle-free sterile vial adapter enables the transfer of any pharmaceutical liquids from vials (with a crimp-diameter of 14mm) to the Comfort-in™ NOZZLE.  The vial adapter is then pressed firmly onto the tip of the vial and then the NOZZLE can be screwed into the Comfort-in™ vial adapter.  Once the contents of the vial have been used up, the vial adapter and the vial are disposed of.
