Frozen pieces o sterile medium, such as saline, are dislodged from a sterile drape container in a surgical slush producing machine by manipulating the drape relative to the cooled basin to which the drape container conforms. Manipulation of the drape is achieved by pushing, twisting, pulling, lifting, etc. on the drape to displace it from the basin. Such movement of the drape may be effected on a continuous and automatic basis, or by manual means using a member or implement to facilitate drape movement. The system cabinet includes a refrigerated compartment for pre-chilling sterile liquid to be used in forming the surgical slush. |
