Embodiment Construction

[0062] figure 1 A schematic cross-section of a medical spray device according to the invention is shown. On the back of the injection device a holder is provided with an internal thread 1 for receiving the CO 2 External thread 2 of compressed gas tank 4. A rotary handle member 6 is fastened to the base of the compressed gas canister 4 to facilitate rotation of the compressed gas canister 4 and fastening of the compressed gas canister 4 into a holder of the spray device.

[0063] A hollow spike 8 is arranged in the holder and serves to open the compressed gas tank 4 and is connected to a pressure line 9 for compressed gas. As the compressed gas tank 4 is screwed in, the compressed gas tank is pushed onto the hollow spike 8 via the cover ready to be opened, so that the compressed gas tank 4 opens and the compressed gas from the compressed gas tank 4 flows into the hollow spike 8 and It thus flows into the pressure line 9 . An evaporation space 10 or evaporation container 10 ...

Abstract

The invention relates to a medical spraying device for irrigating a wound, in particular a lavage system, having a liquid resevior for a medical irrigation liquid or a connection for such a liquid reservior and a compressed gas reservior. The compressed gas reservior is connected or connectable via a pressure line to the liquid reservior, such that the irrigation liquid can be pushed by the gas pressure of the compressed gas reservior acting on the irrigation liquid thorugh a nozzle in order to produce a spray cone. The nozzle is proivded with a plurality of opens which are arranged in way with angles.The irrigation liquid away from the opens is jetted in a pulverization space and / or an discharge opening of the nozzle and a spray cone is produced from the pulverization irrigation liquid. The invention also relates to usage of the medical spraying device to produce a spray cone for removing infected organiations, and also relates to a method for producing the spray cone of the medical irrigation liquid.

Description

technical field [0001] The invention relates to a medical spray device for washing wounds, in particular to a cleaning system and the use of the spray device. [0002] In addition, the present invention also relates to a method for generating a spray mist cone using a medical spray device. [0003] Accordingly, the present invention relates to a medical spraying device for trauma surgery and orthopedics driven by compressed gas. The spraying device may consist essentially of plastic and is preferably intended for single use. Background technique [0004] Medical jetting devices are commonly referred to as cleaning systems in the medical field. Cleaning systems are widely used in surgery to clean tissue areas during an operation (OP). Here, saline solution and Ringer's solution are commonly used as irrigation fluids. With the cleaning system, a spray cone or spray jet is generated with the irrigation liquid and impinges on the tissue areas to be cleaned and exerts a mecha...
