Bionix ShotBlocker® helps healthcare providers minimize needle injection pain associated with injection administration at half the cost of competitors.

Problem: Needle apprehension and pain can create anxiety associated with injections for all patients, children through adults. Anesthetic creams and freezing sprays can be costly, can damage the skin, and take time before working.

Solution: ShotBlocker®, a novel application of the Gate Theory of Pain Management, uses a number of blunt contact points to saturate the sensory signals around an injection site distracting the patients from the pain signals of the needle poke.

Results: A simple, non-invasive, drug free method that instantly reduces needle plain and anxiety at half the cost of other methods.

Frequently Asked Questions

How does the ShotBlocker work?

Shotblocker’s ability to block pain is based on the Gate Control Theory of Pain Management. The theory states that there is a gating mechanism in the spinal cord that can be either opened or closed. When opened, pain signals are transferred through small nerve fibers to the brain and a pain sensation is experienced. It has been found that the gate can be closed by simultaneous stimulation of large diameter nerve fibers, those that respond to touch.

Are there studies that prove ShotBlocker blocks the pain of injections?

Bionix Medical Technologies partnered with Flower Hospital in Toledo, Ohio to complete a study on the effectiveness of the ShotBlocker device. The results of the study show that the ShotBlocker significantly reduced pain from minor injections.

What is the added cost to injection procedures when using ShotBlocker?

At about .50 per device, the cost of ShotBlocker will be minimal compared to other methods that are currently used.

Why is ShotBlocker single-patient use?

ShotBlocker is designed to be single-patient use in order to promote a sterile environment during injection procedures. The single-patient use feature of the ShotBlocker also eliminates the cost associated with resterilization.

How many are there in a box?

ShotBlocker is available in two different quantities; 50 per box and 100 per box.

Used this product extensively with pediatric vaccinations with great results. Even worked well on adults with needle phobias. Was disappointed when it was transiently off the market but looking forward to using it again with its return to market.

One of the most awesome

One of the most awesome devices to alleviate the pain from shots. We have patients coming in asking for "shotblocker" by name, because of the prior experience. My nurse herself is afraid of needles and has one anytime she needs her allergy shots.

Fantastic!!!! The children in my

Fantastic!!!! The children in my practice ask for it (ShotBlocker) before the visit begins. Parents too. It works well, even if by placebo effect, and is so incredibly simple. Thanks so much for bringing it back to market and keep up the great work.
