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);
- wherein the holder (11) comprises at least one connection means (20, 21) for connection with a hose bending device (8).
2 more elements
A hose bending device (8) comprising:
- a holder (11) configured to be fixedly positioned on first and second legs (13, 14) of a fluid hose (5) such that the fluid hose forms a loop (12) projecting from the holder (11) with the first and second legs (13, 14) extending along an insertion direction and being connected at a free head (15) of the loop (12) such that the holder (11) and the loop (12) form a plug;
- an insertion area (16) configured to receive the loop (12) of the fluid hose (5) inserted in the 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.
