Pilot Safety Study to Determine the Ability of the Protector Cap Jet Injector to Prevent Cross-Contamination
Device: Jet Injector with Protector Cap (HSI-500)
|Study Design:||Allocation: Non-Randomized
Endpoint Classification: Safety Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Prevention
|Official Title:||A Pilot Safety Study to Determine the Presence of Hepatitis B Virus in Downstream Injection Samples Using the HSI-500 Jet Injector With Protector Cap|
- Presence of hepatitis B virus in post-injection saline samples as verified by a polymerase chain reaction (PCR)-based assay
- Evaluation of injection site reactions by observation and self-report of pain on a scale (none, mild, moderate, severe)
|Study Start Date:||October 2004|
|Estimated Study Completion Date:||January 2006|
The jet injector is a needle-free injection device that uses a high-pressure stream to penetrate the skin and deliver medication into intradermal, subcutaneous, or intramuscular tissues. Multi-dose jet injectors are a type of jet injector with a reusable fluid path that consists of the vial adapter, dose chamber, fluid pathway, and nozzle. Although credited with decades of use and the delivery of millions of doses of vaccine in the field, multi-dose jet injectors are no longer used due to evidence of cross-contamination between injections. The HSI-500 Jet Injector with Protector Cap has been designed with a disposable plastic cap that acts as a shield between the nozzle and the skin to eliminate cross-contamination between injections while maintaining a high rate of vaccine delivery to multiple patients.
The objective of this pilot safety study is to provide a preliminary indication of the ability of the jet injector to prevent cross-contamination from hepatitis B virus between volunteer injections. A secondary objective of the study is to test study procedures prior to a larger-scale safety study.
