Abstract

The invention proposes a medical applicator ( 300 ) for spraying one or more fluid substances with compressed gas, a spraying device constructed accordingly, and a method for applying the spraying device. In order to avoid excessive air pressure, the spray head has an overpressure valve (310). The overpressure valve vents the compressed gas from the spray head if the air pressure exceeds a threshold pressure. The risk of gas embolism in medical applications of such spray heads can thus be reduced.

Description

technical field

[0001] The invention relates to a spray head for connection to at least one reservoir with a flowable substance and for spraying the substance with compressed gas, for example compressed air or another compressed gas such as carbon dioxide. Background technique

[0002] Furthermore, spray heads for spraying one or more substances with compressed gas assistance are used in the medical field, for example for spraying medical two-component adhesives based on fibrinogen and thrombin. Such so-called fibrin glues are used in medicine, for example to close wounds, stop bleeding (hemostasis) or as tissue adhesives to secure skin grafts. Such a spray head is connected for use to one or more reservoirs with the substance to be sprayed, for example to a single syringe with already premixed adhesive or to a double syringe with the components of the adhesive. To spray the substance, the spray head is on the one hand charged with compressed gas in order to generate a comp...
