Blasting device and containment

Abstract

Disclosed herein is a containment system for a blasting device to prevent release of resulting particulate material into the environment. The system comprises a blasting device having at least one fluid jet nozzle for delivering a stream of particles under pressure toward a substrate positioned on a supporting platform. The containment is a plastic, flexible container having openings penetrated by the at least one fluid jet nozzle and supporting platform. The openings are sealably attached to the blasting device to isolate the interior of the container and the device from the outer environment.

1 . A deposition system comprising:
 a blasting device comprising at least one fluid jet nozzle for delivering a stream of particles under pressure toward a substrate positioned on a supporting platform;   a plastic, flexible container having openings penetrated by the at least one fluid jet nozzle and supporting platform, the openings being sealably attached to the blasting device to isolate the interior of the container and the device from the outer environment;   wherein upon delivery of the stream of particles, the system prevents escape of particulate matter into the outer environment.   
   
   
       2 . The system of  claim 1 , wherein the container is disposable. 
   
   
       3 . The system of  claim 1 , wherein the container is prevented from collapsing by attachment to a rigid framework. 
   
   
       4 . The system of  claim 3 , wherein the rigid framework is positioned the exterior of the container. 
   
   
       5 . The system of  claim 1 , wherein the container further comprises at least one additional opening sealably attached to an exhaust pipe. 
   
   
       6 . The system of  claim 1 , wherein the container further comprises at least one additional opening sealably attached to an inlet for an inert gas. 
   
   
       7 . The system of  claim 1 , wherein the container has a resealable opening allowing access to the container from an area outside the system. 
   
   
       8 . The system of  claim 1 , wherein the container includes an integrally connected pair of gloves allowing manipulation within the container without exposure to the atmosphere outside of the system. 
   
   
       9 . The system of  claim 1 , wherein the openings are sealably attached to the device via an o-ring. 
   
   
       10 . The system of  claim 1 , wherein at least one fluid jet nozzle delivers a stream of particles under a pressure ranging from 0.5 to 100 bar. 
   
   
       11 . The system of  claim 1 , wherein the at least one fluid jet operates at a pressure ranging from 1 to 30 bar. 
   
   
       12 . The system of  claim 1 , wherein the at least one fluid jet operates at a pressure ranging from 1 to 10 bar. 
   
   
       13 . The system of  claim 1 , wherein the stream of particles has particle sizes ranging from 0.1 μm to 10,000 μm. 
   
   
       14 . The system of  claim 1 , wherein the stream of particles comprises a therapeutic agent.
