Definitions

• the loss of a member or part of it represents a profound change in the physical activities and psychological well-being of the human being, as well as influences all leisure and professional activities.
• One way to soften and relocate the individual within daily tasks is the placement of prostheses at the site of the amputated limb.
• the primary purpose of this device is to make the use of lower limb prostheses more comfortable and safer while offering greater safety to the amputee.
• State-of-the-art devices utilize either a knee brace that hinders free knee movement and cause wearer skin irritation or prosthetic interfaces (liners) with sealing rings attached to the inside of the stump. socket that does not fit or fit perfectly, limiting and making it difficult for the user to use the prosthesis.
• the claimed device utilizes an isolated, adjustable T- ring seal that fits over a prosthetic interface (liner) or directly onto the stump (what remains of an amputated limb), and also features a air venting into the socket that helps create a vacuum between the prosthetic interface and the socket by sealing them, creating a larger contact area among them and has a number of characteristics of its own development, among which we highlight the following:
• Adjustable height adjustment can be adjusted more proximal position offering greater suction and lever to the limb;
• Figure 1 Corresponds the perspective of the prosthesis and the stump with the prosthetic interface and the ring placed, ready for fitting;
• Figure 2 Represents the prosthetic interface (liner);
• Figure 3 Perspective of adjustable ring for sealing
• FIG. 4 Air exhaust valve perspective.
• the Utility Model Patent for "IMPROVEMENT IN VACUUM SOCKET SEALING DEVICE” (1) is an adjustable sealing ring (3) which has the function of sealing the sockets (4) creating a larger contact area between the same; a prosthetic interface (2) that is used to protect the leg from direct contact with the socket (4); a socket (4) which is the rigid part of a prosthesis (where the leg enters and fits); an air exhaust valve (5) which is located and connected to the rigid socket (4) and has the function of automatically expelling the air (it does not let air in, only out).
• the sealing ring (3) of the vacuum socket (4) is flexible and is placed directly on the residual limb or on the prosthetic interface (2), which covers the residual limb, with the function of sealing the sockets (4).
• lower limb prostheses (1) creating a hermetically sealed environment, this allows the residual limbs to be able to fit the prostheses (1) using as adjustable and proximal a seal as possible and as a consequence creating a larger contact area with the socket (4) offering great safety to the amputees;
• the preformed ring (3) is offered in several different diameters to be selected according to the mail diameter of each patient's stump; It is uniform in shape, without splicing or joining It is made of flexible material to allow it to fit the most varied stump formats and, of course, the internal design of the sockets to which the ring (3) will seal.
• the patient places the sealing ring (3) over the limb, whether or not using a smooth, flexible prosthetic interface (2) without grooves or designs, and for the new system to work, it is necessary to rigid socket (4) transtibial or transfemural, an air release valve (5) connected in the distal position of that socket (4) and the sealing ring (3) surrounding the patient's stump or prosthetic interface (2);
• the hermetic seal caused by the ring (3) at the moment of insertion of the stump into the rigid socket (4) causes the valve (5) to continuously expel air until the complete insertion of the stump into the socket (4);
• the sealing ring (3) will create airtight seal in the socket (4) and with no air caused by valve action (5), this set of factors will provide a vacuum environment in the socket (4), providing greater contact area and great safety for prosthesis fixation (1);
• the sealing ring (3) adheres to the stump or the prosthetic interface (2) is made by contact only, without any addition of glue or adhesives, when setting the right diameter for the patient, the ring (3) will fit the
• the size of the ring (3) is first defined according to the circumference of the limb with the prosthetic interface (2); the sealing ring (3) is then positioned as close as possible, increasing suction and stump leverage by pushing the member to the end of the socket (4) and letting air escape through the exhaust valve (5) .
• To remove the prosthesis simply actuate the expulsion valve (5).
