Intradermal Adapter
PATH
Solution Overview & Benefits
The intradermal adapter makes ID injections easier. It facilitates the procedure by standardizing injection depth and angle.
An adapter that standardizes injection depth and angle could serve to expand the pool of health care workers capable of performing ID injections with a needle and syringe, and have a favorable impact in campaign delivery scenarios. In addition to fIPV, an ID adapter could be used for fractional delivery of other vaccines which are expensive or in short supply, such as rabies vaccine.
Despite these benefits, adoption of fIPV is not yet universal, due in part to concerns regarding the difficulty and lack of reliability of giving an intradermal (ID) injection correctly using the Mantoux technique with a traditional needle and syringe. In many countries, only certain health care workers routinely perform ID injections, for delivery of post-exposure prophylaxis rabies vaccine and bacillus Calmette-Guérin, a vaccine that is administered at birth to prevent tuberculosis.
History & Development
PATHS's mission is to advance health equity through innovation and partnerships.
PATH developed an ID adapter in partnership with SID Technologies LLC, advancing it forward from the initial concept stage through the manufacture of clinic-ready devices.
As part of this effort, we modified and tested successive design prototypes, incorporating feedback from health care workers in the United States and India.
The design was transferred to commercial partner West Pharmaceutical Services, Inc., which is working with a syringe manufacturer (Helm Medical) on regulatory clearance, manufacturing, and distribution.
Clinical trials and pilot studies have demonstrated safety, efficacy, usability, and health care worker preference for the ID adapter for fIPV, and WHO has purchased a supply of 4 million devices for use by countries interested in introducing fractional dose delivery.
