Description

“IMPROVEMENT IN VACUUM SOCKET SEALING DEVICE”.

1 - INTRODUCTION The loss of a limb 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.

2 - FIELD OF APPLICATION

This descriptive report for Utility Model Patent for “IMPROVEMENT IN VACUUM SOCKET SEALING DEVICE” refers to a modern, lightweight, easy-to-fit, and very comfortable device for use in the area of orthopedics which, when in use, will facilitate and improve the quality of life of users of removable lower limb prostheses by allowing them to perform all movements (walking, sitting, climbing stairs, etc.) safely and firmly.

3 - PURPOSE The main purpose of this device is to make the use of lower limb prostheses more comfortable and safer offering greater safety to the amputee.

4 - TECHNICAL STATE

State-of-the-art devices utilize either a knee pad that hinders free knee movement and cause wearer skin 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.

5 - TECHNICAL DIFFERENTIAL

In order to offer alternatives and improvements to the market, the claimed device utilizes an insulated and adjustable sealing ring, which fits over a prosthetic interface (Hner) or directly into the stump (what remains of an amputated limb), and also features a valve. expelling air into the socket which helps to create a vacuum between the prosthetic interface and the socket, sealing them, creating a larger contact area between them and having a number of developmental characteristics, among which we highlight the following: - It has uniform format, without seams or joints. - It is made of flexible material, to allow the good adaptation to the most varied sizes, and of course, to the internal design of the sockets to which the ring will seal. - Allows the user to fit the sealing ring over the member using or not a liner interface; - This is a precast ring that is offered in several different diameters to be selected according to the correct diameter of each patient's stump. - Replaces the use of knee pads, allowing free movement of flexed knee extension, facilitating gait and sitting; - Keeps; the skin of the thigh free from contact with the knee, also reducing the temperature and possible irritation; - Adjustable height adjustment, can be adjusted more proximal position offering greater suction and lever to the limb; - Lighter for the prosthesis as it replaces the knee brace with a ring of few grams in weight; It's tough, lasts far longer than a knee brace.

7- DESCRIPTION OF THE PATENT The Utility Model Patent for "IMPROVEMENT IN VACUUM SOCKET SEALING DEVICE" (1) consists of an adjustable sealing ring (3) which has the function of sealing the sockets (4) creating a greater contact area between them; 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). of 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 correct diameter of each patient's stump; It has a uniform shape, without splices or joints; 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.

Directions for use: 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 circumference of the stump by contacting it, for example allowing it to be positioned in more proximal or distal regions of the stump, which is a great advantage especially for short stumps as they cannot be moved up or down.

In summary, 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).

8 - CONCLUSION

It can be seen from the present description and accompanying illustrations that the product hereby exhibits characteristics of novelty and originality, representing a perfection which fits perfectly within the rules governing the Utility Model Patent and has considerably improved the existing products, as well as filling an important gap in the market, deserving for what has been exposed and, consequently, their PRIVILEGE.
