Claim Text:
1. A medical lock for a pressure vessel for human occupancy comprising: a body tube for penetration mounting with a shell of said pressure vessel, with an outer end of said body tube extendable outside said pressure vessel whilst its inner end is disposed inside said pressure vessel; an outer door flange connected to said outer end of said body tube; an outer door in sealing face relation with an inside face of said outer door flange; a substantially horizontal rail mountable on each of two inside walls of said body tube; a slant rail mountable below each said substantially horizontal rail and at an angle to said associated substantially horizontal rail so that the slant rails incline towards said outer door flange; a first support axis, which extends out of each of two sides of said outer door; and a second support axis, which extends out of each of two sides of said outer door in spaced apart relation with said first support axis; wherein extended ends of said first support axis are constrained to move on said substantially horizontal rails and extended ends of said second support axis are constrained to move on said slant rail so that when said outer door is being opened by lifting it upwardly in a substantially vertical manner, said outer door is then retracted into an upper part said body tube in a substantially horizontal orientation, or is closed in a reversed manner, such that during opening or closing, said outer door is made to go partly around and above food, water, medicine and/or supplies disposed in said body tube; and wherein, when said outer door is in the closed position, pressure inside said medical lock allows said outer door to be self-locking and self-sealing.
