摘要:
Various embodiments disclosed herein relate to needle-based injectors that incorporate a power assembly comprising a stored energy source and a rate control assembly. The power assembly may be further configured to allow the injection to be performed with more force than a user may be capable of delivering, while also allowing the user to maintain control of the injection process after the stored energy source has been released and the injection has begun, such the user may increase or decrease the rate of injection, or stop the injection, during the injection process. In various embodiments, the power assembly may comprise spring- or gas-based stored energy sources, and/or may comprise friction- or tension-based rate control assemblies. Described herein are also methods for injecting an agent using embodiments of the devices described here.
