Abstract
The invention provides a description of a method and a device suitable for producing a cell suspension spray with living cells, and the produced cell preparation, suitable for grafting to a patient. In contrast to other methods, the spraying is performed through a disposable needle which is inserted into a disposable air tube; which provides a cell distribution avoiding spray nozzles. Small suspension droplets are provided instead of cell nebulization. By using medical grade sterile Luer-lock disposables from medical routine praxis, biocompatibility and easy application is addressed. In applying the method and/or in using the device, cells suitable for grafting to a patient are dispersed in a solution and sprayed with the device for distribution over the recipient graft site.
