The suction device comprises a suction vessel with a cover, the latter be provided with a projecting member. A rubber-like elastic membrane is fixedly mounted onto the top part of the projecting member. The cover comprises a first connector having its passage connected with the inner space of the suction vessel, and a second connector having its passage connected with a chamber bounded by said projecting member and the membrane. The two connectors are connected with each other by means of a connecting hose, shortly before evacuating the inner space of the suction device, at the latest, with the result, that the same negative pressure will prevail in the chamber as in the inner space of the suction device. For carrying out the wound drainage the connecting hose is detached from the connector pertaining to the chamber and is connected with a suction conduit leading to the wound. It is thus possible to avoid--during the time of storage elapsed between putting the evacuated suction device in a state of readiness and using it for wound drainage--any effects of fatigue in the membrane as well as any passage of gas through the membrane into the inner space of the suction vessel, by diffusion, even if the membrane is designed thin.
Suction device for the drainage of wounds, the device comprising a suction vessel, a connection hose fastened to a first connector of said suction vessel and adapted to connect the inner space of said suction vessel with a suction conduit, a clamp for compressing the connection hose, and an indicating device adapted to indicate the pressure difference between the surroundings and said inner space and comprising an elastically deformable membrane mounted on said suction vessel and provided with a first surface bounding said inner space and a second surface facing away from said inner space, wherein said second surface of the membrane is arranged to bound, together with a member of said suction vessel, a chamber, and wherein said member of said suction vessel is provided with a second connector adapted to be detachably connected with one end of the connection hose when said inner space of the suction vessel is at least partially evacuated in turn to be connected to the suction conduit before performing a wound drainage, said member of said vessel comprises a ring-shaped part protruding towards said inner space and wherein the peripheral part of said membrane is fixedly mounted, by means of a ring, on a ring-shaped surface of said ring-shaped part, wherein said membrane including its peripheral, fastened part is arranged completely inside the vessel.
A suctioning method using a suctioning device comprising a suction vessel, a connection hose fastened to a first connector of said suction vessel and adapted to connect the inner space of said suction vessel with a suction conduit, a clamp for compressing the connection hose, and an indicating device adapted to indicate the pressure difference between the surroundings and said inner space and comprising an elastically deformable membrane mounted on said suction vessel and provided with a first surface bounding said inner space and a second surface facing away from said inner space, wherein said second surface of the membrane is arranged to bound, together with a member of said suction vessel, a chamber, and wherein said member of said suction vessel is provided with a second connector adapted to be detachably connected with one end of said connection hose when said inner space of the suction vessel is at least partially evacuated in turn to be connected to the suction conduit before performing a wound drainage, said method comprising the steps of:
A suction device connectable to a suction conduit for the drainage of wounds, comprising:
