A pressure-resistant hull for a submersible, includes unit hulls, reinforcing ribs, connecting channels, and closure heads. A plurality of unit hulls are provided, and are sequentially strung together spiralling upward or spiralling downward, the closure heads being arranged on the unit hulls at the first position and the last position respectively, an observation window being provided on each unit hull respectively, adjacent two unit hulls in a horizontal direction being respectively connected by means of a reinforcing rib, and at least two connecting channels being provided between adjacent two rings of the unit hulls in the vertical direction. The design method includes using a spiral joining structure to facilitate organic adjustment of the number of unit hulls, thus having better utilization of space and aiding to greatly expand the space. The sensitivity of the limit load to defects is low, increasing axial rigidity, improving the overall pressure-resistive ability.

This invention makes reference to an autonomous, versatile and non-invasive hyperbaric capsule with a new functional and esthetic design for high-pressured air or oxygen therapies for one or more people which can be installed to any structure. It has vertical to horizontal oscillating effect and features a new bolted gate with a 2-movement, 3-position twin closure mechanism. Also, it has all the necessary equipment already built in ready to be operated according to the wishes of the patient inside or by an assistant in the outside.
