The Current Method
Liquid pharmaceuticals are stored in sealed glass ampules or other storage devices that require filtration. To use pharmaceuticals, healthcare workers must open the glass ampule by snapping the glass neck. As a result, glass shards may be produced. These shards must be removed from the pharmaceuticals before injection.
The process of opening pharmaceuticals is a multi-step process requiring a filter needle or filter straw, in addition to a hypodermic needle. The glass shards are removed by drawing up the solution through a filtered needle or straw secured to the end of a syringe. Once the solution is in the syringe, the filter needle is removed from the syringe. Finally, a new needle is attached to the syringe to administer the pharmaceuticals.
The multi-step process is fraught with risks:
- Contamination from handling creates a risk of sepsis
- Changing the needle delays treatment in time-sensitive situations
- Extra packaging for two needles is wasteful
A single needle solution would decrease the risk of needle sticks and errors by healthcare providers who don’t have readily available filter needles or those trying to cut corners by not complying with safe practice measures. The solution would also cut time, storage space, and medical waste in half.

The CarrTech Method
CarrTech has developed and patented a safer, cheaper, greener solution: The FROG™ filter.
The CarrTech FROG™ filter is a single inline filter and needle all-in-one package. The FROG™ is comprised of an outer cap, an inner filter cover (hermetically sealed according to ISO certified and FDA guidelines), an inner hypodermic needle, and a filter located at the tip of the needle.
To see a longer demo of the CarrTech FROG™ filter needle in action, check out this video.
The FROG™ represents a novel, one-step process that decreases the risk of errors, sepsis, and waste. A single assembly contains both the filter and the needle that will inject the liquid payload. Once the filtered liquid payload is loaded into the syringe, the cap is removed.
Then, the filter needle is inserted into the broken ampule and the drug solution is drawn up into the syringe. Once safely in the syringe, the outer filter is removed, giving way to a new sterile hypodermic needle ready for injection.
The filter needle reduces dead volume, which is the volume within the filtered needle cap filled with a liquid payload that does not enter the open end of the needle. It is a waste of the expensive liquid payload and discarded with the filtered needle cap. Sealing around the open end of the needle prevents the liquid payload from getting beyond the seal and reduces the amount of dead volume.
