Definitions

  • the present invention relates to a hyperbaric chamber for high-pressure medical treatment, with no structural obstacles.
  • a hyperbaric chamber substantially comprises a large vessel in which a given pressure, greater than the atmospheric pressure outside, is formed by external compressors, and which is normally divided into two compartments: a main chamber, and an air lock.
  • the main chamber is normally maintained at the treatment pressure, and is designed to accommodate a number of patients and staff at the same time; while the air lock enables passage of patients or staff into the main chamber while treatment is in progress.
  • incoming patients or staff enter the air lock; the air lock is closed and brought up to pressure; and the communicating door between the main chamber and the air lock is then opened to allow access to the main chamber. The same procedure is repeated in reverse when leaving the main chamber.
  • the doors between the main chamber and the air lock and between the air lock and the outside are normally small, e.g. about 800 mm, and round in shape; and the door to the main chamber is normally round, oval, or in the form of a porthole, and opens either partly or fully. All the doors therefore present major structural obstacles seriously hindering passage to and form the chamber.
  • hyperbaric chambers have been proposed, for example from by document DE-C-4 035 830, wherein the door to the main chamber is rectangular and opens inwards.
  • pressure sealing is assured by a door stop on the flat wall, for the door to open, the inside and outside floors can never be flush; and, though small the step between the two floors poses problems when, as is usually the case, transferring patients in wheelchairs or on stretchers.
  • a hyperbaric chamber for high-pressure medical treatment comprising a floor, and at least one door enabling access to the chamber, said door being rectangular and opening inwards of the chamber; characterized in that said floor is flush with the outside floor, and comprises a portion located at said door, which is lowered when opening or closing the door and which is flush with the floor when the door is closed or fully open.
  • Number 3 in Figure 1 indicates a hyperbaric chamber for medical treatment, e.g. treating divers for embolisms, or similar.
  • Chamber 3 is cylindrical with a curved wall 1 and two flat walls 2, and is divided by a flat intermediate wall 8 into a main chamber 4 and an air lock 5, which present a floor 6 flush with the floor 7 (Figure 2) outside chamber 3.
  • Main chamber 4 presents two rows of seats 9, is normally maintained at the treatment pressure, and may accommodate a number of patients and staff at the same time, whereas air lock 5 presents only four seats 9, and provides for enabling passage by patients or staff into main chamber 4 while treatment is in progress.
  • Main chamber 4 presents a rectangular door 10 opening inwards in any known manner; and, similarly, air lock 5 presents a rectangular door 11 also opening inwards in any known manner.
  • Main chamber 4 and air lock 5 communicate via two rectangular doors 12 and 13 located in wall 8 and hinged at opposite sides 14 and 16 so as to swing in the same direction (anticlockwise in Figure 1) and open inwards of main chamber 4 and air lock 5 respectively.
  • Portion 21 and strip 22 are controlled vertically by respective pneumatic actuators 23 and 24 ( Figure 2) which are activated in response to two sensors (not shown) for respectively indicating when door 10 is fully open and fully closed, and which may, for example, comprise respective pneumatic pistons connected to respective portion 21 and strip 22 by respective toggle joints 25 and 26.
  • portion 21 is flush with floor 6, and may therefore be used as part of the floor by patients and staff inside chamber 4; and strip 22 is in the lowered position enabling door 10 to shut against threshold 19. In view of the narrow width of strip 22, this in no way impedes movement inside chamber 4 when in the lowered position.
  • actuator 23 When door 10 starts to open, actuator 23 ( Figure 2) is activated to lower portion 21 ( Figure 4) so that it is flush with strip 22 and slightly below the bottom edge 17 of door 10; and, when door 10 is fully open, actuators 23 and 24 are activated to raise portion 21 and strip 22 ( Figure 5) so that floor 6, portion 21 and strip 22 form an unbroken surface with the outside floor 7, with no structural obstacles,
  • actuators 23 and 24 are activated to lower portion 21 and strip 22 ( Figure 4); and, when door 10 is fully closed, actuator 23 raises portion 21, while strip 22 remains in the lowered position shown in Figures 2 and 3.
  • Door 11 ( Figure 1) of air lock 5 and/or doors 12 and 13 between air lock 5 and main chamber 4 may also present a movable floor portion similar to portion 21, and a movable strip similar to strip 22, to eliminate any structural obstacles hindering access to air lock 5 or passage between air lock 5 and main chamber 4.
  • door 11 to air lock 5 and/or inner doors 12 and 13 may be provided with a threshold 27 slightly higher than floor 6.
  • hyperbaric chamber 3 According to the present invention, rectangular doors 10-13 provide for troublefree passage to and from chamber 3, and between air lock 5 and main chamber 4.
  • portion 21 and strip 22 eliminate any structural obstacles hindering access to and/or transfer within chamber 3, and also increase the usable area of floor 6 inside chamber 3.
  • portion 21 may be trapezoidal as opposed to rectangular.
