Pneumatic retinopexy injector |
摘要 |
A pneumatic retinopexy injector includes a syringe to which is communicated a controllable gaseous pressure source. A desired volume of a gaseous substance can be injected by the syringe by utilizing a controller to introduce the pressurized gas to the syringe to cause the piston of the syringe to eject any contents of the syringe. The manual controller can comprise a foot pedal having a variable flow pneumatic valve. The invention can also utilize a vacuum source which is switchable to the syringe to allow automatic filling of the syringe.
