Abstract
A control device for controlling and/or regulating an injection flow rate, when injecting a fluid at an injection site between two tissue layers of the human eye with an injection flow rate that increases with time, is described, which comprises a controlling or regulating unit configured to control the injection flow rate in such a way that the injection flow rate increases during the injection for at least 30% of the injection time or during the injection of at least 30% of the injection volume.
Claims15
A control apparatus for open-loop and/or closed-loop control of an injection flow rate when injecting a fluid at an injection site between two tissue layers of the human eye with an injection flow rate increasing over time,
- comprising:
- an open-loop or closed-loop control unit designed for open-loop or closed-loop control of the injection flow rate, in such a way that the injection flow rate increases during the injection for at least 30% of the injection time or during the injection of at least 30% of the injection volume.
A non-transitory computer-readable medium containing computer-readable instructions for open-loop and/or closed-loop control of an injection flow rate when injecting a fluid at an injection site between two tissue layers of the human eye with an increasing injection flow rate, wherein execution of the computer-readable instructions by one or more processors of a computer causes the one or more processors to carry out the step of:
- controlling the injection flow rate such that the injection flow rate increases during an injection for at least 30% of the injection time or during the injection of at least 30% of the injection volume.
A method for open-loop and/or closed-loop control of an injection flow rate when injecting a fluid at an injection site between two tissue layers of the human eye with an injection flow rate increasing over time, the method comprising:
- injecting at an injection flow rate that increases during the injection for at least 30% of the injection time or during the injection of at least 30% of the injection volume.
