Abstract
Devices and methods are disclosed for delivering sealing compound to a wound in animals, including humans. Such wound sealing is important after deep skin penetrating lacerations or subsequent to internal wounds. The apparatus utilize an aerosol dispensing system that both mixes and applies a multi-part sealant compound. The aerosol system includes a plurality of sealant component chambers, a source of pressurized gas, an aerosol mixing head, a pressure regulator, a pneumatic switch, and a component pumping mechanism. The aerosol system, either a reusable or a disposable device, is further provided with a system that keeps dry components from liquid components and then automatically mixes the liquid and dry components prior to application. The system provides for easy control over the application, inexpensive manufacture, and simplified preparation, thus minimizing the time needed for application and enhancing the potential outcomes of the patient.
