What are Needle-free Injections
and How do they Work?

“The liquid becomes the needle”. 
Needle-free injections, also called Needleless or Needle-less injections, are simply an injection without the need to use needles.

A needle-free injection occurs when the injectable medicine (eg. insulin, hormones, local anaesthesia even oily basesd injectable Testosterone ) is pushed into the body through the skin, using a combination of pressure, high velocity and a syringe/nozzle that has been specially designed for this purpose, there are no needles used to deliver the medication. This device is a registered medical device,internationally certified, here we have different injectors suitable for intramuscular or subcutaneous delivery.

Awesome product. This is not something until later in my diabetic journey that I found was an option for insulin delivery without a needle. I buy supplies in the US, so finding someone who is legit and able to send to the US was amazing. The support and how-to videos were great in getting to know the usage of the device. My experience so far has been great. I worked myself up the first time, but once I did it and knew what to expect it is soo much better than an injection or pump site.

We have a miniature schnauzer that was diagnosed with diabetes and she is very difficult to give a regular syringe shot too. The Comfort-In needle free injection has been a life changer for us. We went from it sometimes taking 3 people to give her a shot to just one person. I appreciate the great customer service, so very helpful!! They go above and beyond to walk you through every step and make it simple to use. Thank you for making our life easier. Highly recommend.

All professionals who are currently giving injections with a traditional syringe and needle from a multi-dose vial can use our equipment thanks to our certification.

No More Needle Phobia!

We don’t need to tell you how many people pass out at the sight of a needle; it’s a serious phobia that many people have before receiving any injection. The Comfort-In Injector will provide these patients with a phobia-free injection solution.
Most people who are afraid of needles just forego immunizations.
GP clinics have contacted us with patients who require general anaesthesia prior to simple injections or who are 22 years old and have not been vaccinated since the age of six owing to needle anxiety.
Please have a look at this image; there are so many health workers there to assist this unfortunate individual who simply passed out before her needle was even administered! With our injectors, we can easily avoid this.

Needle Syringe Injection vs Comfort-In Jet Injector
Comparison: Needle Syringe Injection vs Comfort-In Jet Injector

What is Comfort-in™️?

Comfort-in™️ is a spring operated needle-free injection system. This system is a type of medical injecting syringe that uses high-pressure – it uses the narrow jet of the injected liquid instead of a hypodermic needle to penetrate the epidermis (skin). It delivers from 0.01ml up to 0.5ml of any liquid medication (1-50 units), it can also be referred to as a jet injector. It is ideal for personal use to self-administer insulin, hormones, vitamin B-12 and other liquid injectable grade medication.

Frequently Asked Questions

What are Needle-Free Injections?

Needle-free injection is a method of injecting using a jet injector device like Comfort-in™, which injects liquid medicine, anaesthesia, vitamins, or other liquid injectables through the skin and into the subcutaneous tissue, via high pressure. Injections with jet-injectors preserve tissue and prevent lipodystrophy (lumps/small dents on the skin when injections are repeatedly performed at the same spot).

What is the Comfort-in™?

Comfort-in™ is a no-needle injection system for the subcutaneous administration of medication. It injects liquid through the skin and into the subcutaneous tissue via high-pressure, at a speed of 100 metres per second. The Comfort-in™ is the most versatile injector on the market (that we know of), because it can be used for injecting almost any injectable liquid including insulin, anaesthesia, vaccines, growth hormones, sports medicines, medicine for ED, vitamins such as B12, and so much more.

What are the advantages of Comfort-in™?

The Comfort-in™ injection system has many advantages such as:

  • needle-free injection
  • virtually painless
  • reduces tissue damage and scar tissue
  • reduces psychological inhibitions and fears
  • minimises injection-induced stress
  • elimination of injury to patient and physician caused by needle
  • safe and easy use
  • most economical on the market, being good for up to 10,000 injections

What do I need to start needle-free injections?

You just need the basic equipment included in a Comfort-in™ injection kit, which includes:

  • 1 Comfort-in™ injector
  • 1 Comfort-in™ pressure lever
  • 1 Portable pouch
  • 8 sterilised syringes
  • sterilised adapters
  • instructional manual

How does the Comfort-in™ work?

Liquid medications are transferred into the needle-free nozzle/syringe via adapters. There are 5 different adapters available to suit all types of injectable liquid from any type of pen, vial or cartridge. The needle-free nozzle/syringe can contain up to 0.5ml per single injection. After loading the injector, the liquid medication in the nozzle/syringe is propelled effortlessly as a small jet into the body via a spring-action.

The liquid medication disperses into the subcutaneous tissue via the path of least resistance, in a cone-like shape. There are no sharp needles penetrating through delicate skin and tissue. This reduces the likelihood of tissue damage, the formation of scar tissue and the chance of developing lipohypertrophy (lumps under the skin caused by multiple injections in the same area of skin over an extended period of time or re-using the same needle without correct sterilisation). This is a common issue for sufferers of Type 1 Diabetes.

The Comfort-in™ needle-free injection is fast, safe, quickly absorbed by the body and ‘virtually’ painless.

How should the user be prepared for Injecting with the needle-free injector?

The person receiving the injection should be informed about the release noise of the injector to prevent defensive arm movement or startled reflex. Everybody is different and has a different sensitivity level. You can expect to feel absolutely nothing or a small flick like sensation. Also depending on the medication being injected, you may also feel a stinging sensation.

How did I survive without this ?? Being a T1 Diabetic and suffering from extreme needle-phobia I would often skip my medication simply because I didnt want to inject myself. This device takes the pain and anxiety out of insulin-therapy treatment. I find it very easy to set up and use day to day,takes me about 2-3 minutes start to finish. A dramatic difference from the 30 minutes to a hour it would take me each night to fight my anxiety. Extremely well built and designed. A must have product for anyone that has to use needles on a daily basis.
