| 摘要 |
<p>This invention is an improved multi-dose non-needle jet injection device incorporating a reservoir which receives propellant under pressure which is delivered via a valve (21) to three interacting pistons (15A-15C), and cylinders. When the propellant is delivered to the pistons (15A-15C), the pistons (15A-15C) move to eject an injectable material from a reservoir contained within the device as a jet through a nozzle (1) located against the skin of the recipient into the hypoderma.</p> |
