Abstract: A method for producing an endoscopic drape includes positioning a portion of a sheath of flexible material in abutment with a joining portion of a first housing piece. A joining portion of a second housing piece is positioned close to joining portion and the joining portions are then joined together, for example, by ultrasonic welding.  This forms a housing in which the portion of the sheath is entrapped between the first housing piece and the second housing piece. The portion of the sheath may be joined to the first housing piece by a thermoplastic gasket or O-ring prior to joining the first and second housing pieces to improve the seal between the sheath and the housing. The housing includes a clear lens or window that provides an optical pathway through the housing and also provides a sterility barrier.

Patent CA-2294633-A1 (CA)
Inventor: MURRAY JOSEPH C
IPC: F25D13/06
Filed: 1998-07-10
Abstract: Apparatus for preparing packaging materials for use in shipment of heat sensitive materials, utilizes a hydration module (11), a freezing module (40), and a delivery module (45). Rolls of superabsorbent polymer-based refrigerant media (117) in the form of a continuous web of a selected length and width are maintained in dry storage. These may be cut to size along the web material which separates cells containing the superabsorbent polymer. The web or pad is advanced into the hydration module (11) which comprises a dip tank (17) or spray system (26) to provide an adequate supply of hydrating fluid to the superabsorbent polymer. The hydrated web is then conveyed through a freezing chamber (40) having a temperature of -10~ Fahrenheit, or lower, where the fluid absorbed within the cells freezes. The small footprint of the modular system means that necessary handling, including cutting into a suitable size and shape, may be accomplished in the consumer's shipping area for placement around perishable materials in shipping containers.
