Definitions

• the present invention relates to a device for the treatment of peripheral circulatory disorders consisting of at least one treatment cylinder, into which a limb to be treated can be inserted at least partially through a closure device and in which an air supply and discharge device by means of control elements causes overpressure and / or underpressure can be, and in particular the closure device for the treatment cylinder, which avoids a blockage of the veins when an excess or / and negative pressure is caused in the treatment cylinder.
• JUNOD studied the effect of overpressure on the body or one of its extremities and invented devices with which he made hyperbaric baths.
• BEER subjected arms or legs to negative pressure, which caused venous congestion, which he used as a therapeutic measure for rheumatic pain.
• the devices subsequently built have programs with overpressure and underpressure phases. They had a cylinder made of glass or plexiglass, which were closed with a rubber tube, the elasticity of the rubber being used for the closure.
• This method inevitably blocked the veins and, depending on the intensity of the negative pressure, blocked the arteries, so that the treatment as such only used the venous congestion used by beer as a therapeutic measure.
• Inflatable boots made of flexible material are also known, but they can only exert pressure on an extremity, the effect of which, because of the limited surface area, can never reach that which is exerted by direct air pressure.
• the VASOTRAIN device was launched, in which the treatment cylinder was sealed with an inflatable cuff. Despite this improvement in the method of acting on an extremity with overpressure and underpressure, the VASOTRAIN also led to venous congestion and BARBEY describes that treatments with the VASOTRAIN had to be stopped due to the occurrence of petechiae.
• VASCULATOR which also had inflatable cuffs, but the novelty of which was that they kept their pressure on the extremity constantly minimal, ie their internal pressure only rose until the desired overpressure was reached intentional escape of overpressure, both compensated by the pump and by a slight inflation of the cuff, was kept constant.
• the cuff empties continuously and in proportion to the intensity of the negative pressure.
• the closure device has a sleeve which has a thick-walled disk which is covered on both flat sides with thin-walled, highly elastic membranes, that the disk has a first opening and the membranes have a second opening opposite the first opening Openings are provided, the diameter of which is smaller than the diameter of the first opening, and that the treatment cylinder has a rigid support element against which the entire cuff is pressed in a sealing manner by means of gill means. Thanks to their elasticity, these membranes conform to the extremity in such a way that they act as a membrane sleeve, whereby between the Both rubber membranes form an air cushion, which also serves as a non-compressive sealing agent.
• the treatment cylinder is closed in such a way that the intensity of the pressure change can be reached and kept constant for a predetermined period without the cuff having to be inflated, with this solution preventing the venous return flow to the heart from being blocked during the entire duration of the treatment.
• Treatment cylinder hermetically sealed.
• the closure device can advantageously be characterized in that the treatment cylinder is axially movable in order to facilitate the insertion of an extremity.
• the blocking system of the high position simultaneously blocking the treatment cylinder axially. Due to this permanent elevated position of the treatment cylinder, i.e. also during the negative pressure phase, the negative pressure leads to a widening of the capillaries, venules and veins, through reflex action an arteriolar dilation and thus hyperaemia and at the same time an increased venous return to the heart, which, because the Thanks to the closure device according to the invention, the veins of the extremity remain continuous, the volume of which is practically proportional to the arterial filling volume of the vessels of the extremity.
• the closure device does not have to be inflated, as a result of which the electronic control is considerably simplified because it only controls the overpressure and underpressure phases and their constant holding times, which largely prevents breakdowns or malfunctions.

• 3 shows that the rubber membrane 7 clings to the extremity E during an overpressure phase in the cylinder 1 and that the rubber membrane 6, thanks to a deliberate leak between the extremity E and the rubber membrane 7, inflates, so that an air cushion 6A between the two arises that serves as a non-compressing seal.
