Abstract
For producing a high pressure impulse, a hose bending valve is provided that comprises a loop (12) provided in a supply hose of an instrument (2) and a hose bending device (8) provided as multiple-use component. Such a valve is very simply constructed and allows the creation of steep pressure increase flanks with very high pressures up to 100 bar, as are needed for a needleless injection. The sterilization effort is minimal. Also, the material effort is minimal, if single-use components are used.
Claims15
An instrument (2) comprising:
- a fluid applicator (4);
- a first fluid hose (5) that extends from a proximal end thereof to the fluid applicator (4), wherein the proximal end is configured to be connected to a first fluid source (3);
- and
- a holder (11) that is arranged on the first fluid hose (5) that holds the first fluid hose (5) in a loop (12).
1 more element
A hose bending device (8) comprising:
- an insertion area (16) configured to receive a loop (12) of a fluid hose (5) inserted in an insertion direction;
- and
- an actuation device (22) arranged at or about the insertion area (16) configured to deform or release the loop (12) in a controlled manner.
