Abstract
Jet injectors are medical injecting devices that use a high-pressure jet of liquid to replace hypodermic needles. The current approach of the jet generation by gas cartridge, loaded spring or piezo actuator are relatively bulky and are meant to be used for the superficial part of the body. In this study, we present jet generation employing the laser-induced liquid breakdown realized through optical fibres inserted into the round capillary with 0.3 mm inner diameter, and 1,2 mm outer diameter. Using the ultra-fast camera we can observe jet velocity depending on the laser fluence. We further examine the ability to inject liquid into the hydrogel models mimicking mechanical properties of soft tissues. This technology allows shrinkage of the jet injector device into the scale it could be used as a minimally invasive device in an endoscopic probe.
