Oxygen chamber device and treatment system for local hyperbaric oxygen therapy of wounds

Abstract

An oxygen chamber device for local hyperbaric oxygen therapy of wounds includes first and second silicone units. The first silicone unit includes a first annular base wall having opposing first and second surfaces, a silicone film disposed on the second surface, a surrounding wall extending from the first surface, and a retaining block disposed on the inner annular surface of the surrounding wall. The second silicone unit includes an annular wall located within the inner annular surface, a retaining groove disposed on the outer annular surface of the annular wall and fixed to the retaining block, a cover wall extending from one end of the annular wall away from the first surface to define a space, an air inlet connector protruding from the outer surface of the cover wall, and a valve disposed on the inner surface of the cover wall. The cover wall has an air inlet penetrating the inner and outer surfaces, and the air inlet connector has a channel communicating with the air inlet and allowing oxygen to flow. The valve is located adjacent to the air inlet and is movable between a first and a second position; when the valve is in the second position, it can block oxygen from passing through the air inlet.

Claims

1. An oxygen chamber device for local hyperbaric oxygen therapy of wounds, comprising: oxygen input to its interior, and including: A first silicone unit includes a first annular base wall having a first surface and a second surface disposed opposite to each other, a silicone film disposed on the second surface, a surrounding wall extending from the first surface away from the second surface, and a first connecting member disposed on an inner annular surface of the surrounding wall; and a second silicone unit includes an annular wall located within the inner annular surface, a second connecting member disposed on an outer annular surface of the annular wall and fixed to the first connecting member, a cover wall extending from one end of the annular wall away from the first surface to define a space, an air inlet connector protruding from an outer surface of the cover wall away from the space, and a valve disposed on an inner surface of the cover wall. The cover wall has an air inlet penetrating the inner and outer surfaces, the air inlet connector has a channel communicating with the air inlet and allowing oxygen to flow, and the valve is adjacent to the air inlet and movable between a first position and a second position. When the valve is in the second position, it can block oxygen from passing through the air inlet. The first connector is selected from either a card block or a card slot, and the second connector is selected from either the card block or the card slot.

2. The oxygen chamber device for local hyperbaric oxygen therapy of wounds as described in claim 1, wherein, The at least one card block is a convex ring, and the at least one card slot is a concave ring.

3. The oxygen chamber device for local hyperbaric oxygen therapy of wounds as described in claim 1, wherein, The end of the annular wall is adjacent to the first surface of the first annular base wall. The second silicone unit also includes a second annular base wall. An outer periphery of the second annular base wall is connected to the end of the annular wall. The air inlet of the cover wall of the second silicone unit is away from the first annular base wall relative to the second annular base wall. An inner periphery of the second annular base wall is connected to a periphery of the cover wall away from the air inlet.

4. The oxygen chamber device for local hyperbaric oxygen therapy of wounds as described in claim 3, further comprising a clamp for holding the enclosure wall of the first silicone unit and the annular wall of the second silicone unit, the clamp being used to strengthen the bonding strength between the first connector and the second connector.

5. A treatment system comprising: an oxygen chamber device for local hyperbaric oxygen therapy of wounds as described in any one of claims 1 to 4; and an oxygen cylinder unit comprising: An oxygen cylinder has a body defining a chamber, oxygen disposed in the chamber, an outlet valve body disposed on the body and connected to the chamber, a pressure reducing valve assembly having a valve seat connected to the outlet valve body and having a pipe connected to the chamber, a pressure gauge disposed on the valve seat and connected to the pipe, a flow control element disposed on the valve seat and connected to the pipe, and an outlet connector disposed on the valve seat and forming a flow channel connected to the pipe; and a delivery pipe having a first end fitted on the outlet connector and a second end opposite to the first end fitted on the inlet connector.
