DEVICE FOR PRODUCING A FLUID JET

摘要

A device for producing a fluid jet suitable for hygienic requirements in mechanical wound cleaning, including removal of biological tissue, may include a drive casing with a drive and a pump module with a pump casing which can be detachably joined. The drive casing may include a positive-locking element and the pump casing may include a positive-locking counter-element. The positive-locking element may interact with the positive-locking counter-element so that the pump casing is imposed a pivotal motion relative to the drive casing until reaching a final position. In final position the pump casing may be connected to the drive casing and a drive element may be connected to an associated drive counter-element. Drive element and drive counter-element may be arranged eccentric to a pivot axis of the pivotal motion and may be formed so a positive-locking connection arises between the drive element and drive counter-element due to the pivotal motion.

1. A device for producing a fluid jet for the removal of biological tissue, with a drive provided in a drive casing and a pump module comprising a pump casing said drive casing and said pump module can be detachably joined, wherein said drive casing comprises at least one positive-locking element and said pump casing at least one positive-locking counter-element, wherein said positive-locking element when joining said pump and said drive casing interacts with said positive-locking counter-element such that said pump casing is, until a final position has been reached in which said pump easing is connected to said drive casing and at least one drive element of the drive provided at said drive casing is connected to an associated drive counter-element of said pump module, imposed a pivotal motion relative to said drive casing, wherein said drive element and said drive counter-element are arranged eccentric to a pivot axis of said pivotal motion and configured such that a positive-locking connection between said drive element, and said drive counter-element arises due to the pivotal motion.
