Description

Tight liner for artificial limb

More particularly, the present invention relates to a sealing liner for a will, which is easily deformed by weight pressure and is wrapped around the end surface of a truncated conical part so as to induce comfortable walking without causing pain in the shoulder wear Lt; RTI ID = 0.0 > liner < / RTI >

The prosthesis is an artificial prosthesis that complements the physical deficit of the limb. The upper part of the prosthesis is attached with a socket that supports the body cut.

The lower limb amputee wears the will, and the limp limb forces the will socket to move the limb while walking.

The will socket is a sensitive part that is in direct contact with the truncated part and acts on weight load and gait.

However, even in the case of a socket that is well fitted to the cutout, stress on the cutout is given by the continuous load and the biased pressure during the walk. Generally, it is known that the inconvenience of wearing a shoulder is caused by a load impact applied to the end of the truncated cone.

In order to alleviate this inconvenience, the liner made of stretchable material is first applied to the cutout before wearing the socket for the will.

On the other hand, currently widely used silicone liners are inserted into hard sockets and serve to protect the skin of the body part. The lower end portion of the silicon liner is made to have a structure in which the silicon layer is thickened to relieve the pressure and impact applied to the end of the piercing portion.

However, the shock absorbing method of the lower portion of the liner using the elasticity of such a material has a limitation in that it can not sufficiently solve the load impact continuously applied to the cutting portion.

This limita- tion of the cushioning function of the lower part of the liner is generally associated with inconveniences such as pain during prolonged use.

In addition, in the case of an irregular shape such as an asymmetrical shape and a bone protruding shape at the end portion of the truncated conical part, the pressure is uneven even when the liner is worn, which causes discomfort when walking.

In general, research has shown that until the trunk is adapted to body weight, it causes pain in the legs, and about 30% of the triceps suffer from pain when wearing the legs.

In order to overcome such a problem, a liner for the Korean Patent Application No. 10-2008-0133668 has been proposed.

However, in the case of the various types of liner disclosed in the above document including the will liners, it is known that it causes pain to the wear of the legs due to physical properties and structural limitations, It is necessary to develop a technique for a sealed liner.

Korea Patent Office Application No. 10-2008-0097278 Korea Patent Office Application No. 10-2008-0111816 Korea Patent Office Application No. 10-2008-0133668 Korea Patent Office Application No. 20-2008-0017013

The object of the present invention is to provide a sealing liner for a shoulder which is easily deformed by weight pressure and closely attached to an end surface of a truncated conical part so as to effectively alleviate the pain associated with wearing the shoulder, will be.

The object of the present invention can be achieved by a cylindrical body having an open upper portion; And a silicon thin film sealing the upper opening of the cylindrical body and supporting the end of the recessed cut portion with a sealing internal pressure.

The cylindrical body may be provided with a first flange, and a second flange paired with the first flange may be provided on the first flange, and an edge of the silicon thin film may be provided between the first flange and the second flange. As shown in Fig.

The silicon thin film may have a circular shape in a plan view and the circular edge end region of the silicon thin film may be made thicker than the central portion so as to have a required tensile strength, So that it has a concave shape so as to have a structure in which it is closely attached to the surface of the end portion of the end portion.

And a connector coupled to the upper portion of the second flange by the screw to connect the silicone sleeve so as to have a suspension function.

And a socket adapter may be further provided at an outer lower end of the cylindrical body to be coupled with a socket for a shoulder.

The outside of the cylindrical body may further include an air adjusting unit for adjusting the internal pressure of the cylindrical body to be hermetically sealed.

According to the present invention, there is an effect that it is easily deformed by the weight pressure and is wrapped tightly on the surface of the end portion of the truncated conical portion, thereby effectively relieving the pain upon wearing the shoulder, thereby inducing comfortable walking.

In addition, as a result of receiving a constant pressure, the piercing portion inserted into the sealing liner of the present invention not only reduces the pain but also relieves wounds and pain caused by unevenness at the end of the piercing portion.

Fig. 3 is a view showing a state in which the support body is pressed against the sealing liner of Fig. 2; Fig.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

Fig. 2 is a structural view of a closed liner according to one embodiment of the present invention; and Fig. 3 is a cross-sectional view of a closed liner for a shoulder of Fig. 2, FIG.

Referring to these drawings, the sealing liner 100 according to the present embodiment has a structure that is easily deformed by the weight pressure (in the direction of the arrow in Fig. 3) and tightly attached to the surface of the end portion of the truncated conical portion, Thereby relieving the pain effectively and inducing comfortable walking.

The sealing liner 100 is provided with a cylindrical body 110, a silicon thin film 120, a first flange 111 integrated with the cylindrical body 110, and a pair of first flanges 111 A flange 112, a connector 130, a socket adapter 150 provided at an outer lower end of the cylindrical body 110, and an air conditioning unit 160 installed at an outer side of the cylindrical body 110.

The cylindrical body 110 forms the outer appearance of the sealing liner 100 for a can according to this embodiment.

The cylindrical body 110 may be made of a metal material, for example, stainless steel, which is resistant to pressure and is resistant to corrosion.

However, the scope of the rights of the present embodiment is not limited to the material thereof. That is, the cylindrical body 110 may be made of a material other than stainless steel.

A first flange 111 is formed on the cylindrical body 110. The first flange 111 is formed at an end of the cylindrical body 110, and may be integrally formed with the cylindrical body 110.

A second flange 112 paired with the first flange 111 is provided above the first flange 111.

The cylindrical body 110 may have a container shape that is not necessarily, but narrowed downwardly as shown in the figure.

A socket adapter 150 is provided at an outer lower end of the cylindrical body 110. The socket adapter 150 may be welded at the outer lower end of the cylindrical body 110 to allow the prosthetic socket to be worn through the socket adapter 150.

The air adjusting unit 160 is installed at the outer side of the cylindrical body 110 to control the internal pressure of the cylindrical body 110 to be sealed.

The second flange 112 is disposed in pairs with the first flange 111 above the first flange 111 as described above.

A connector 130 is disposed on the upper portion of the second flange 112. That is, the connector 130 is padded on the upper portion of the second flange 112, and then is fastened with the second flange 112, the silicon thin film 120 and the first flange 111 with screws B to form a body .

The connector 130 is for connecting a silicone sleeve and may have a different shape from that shown in the figure, so that the scope of the present invention can not be limited to the shape of the figure.

The connector 130 and the socket adapter 150 to which the silicone sleeve is connected allow the sealing liner 100 for the will according to the present embodiment to have a willingness function.

On the other hand, the silicon thin film 120 is a thin and flexible silicone material so as to be easily deformed by the pressure, covers and covers the open top of the cylindrical body 110, and functions as a site directly receiving the body pressure (arrow direction in FIG.

The reason why the thickness of the silicon thin film 120 is not damaged even if it is thin is that the principle of the tire tube is applied.

The silicon thin film 120 applied in the present embodiment has a circular shape when seen in plan view.

And the center portion is concave downward to easily enclose the truncated conical portion. In addition, the edge region of the circular edge is made thicker than the central portion, so that the required tensile strength can be obtained.

In other words, the silicon thin film 120 is formed so that its thickness progressively increases from the central portion to the circular edge region.

The open top of the cylindrical body 110 can be sealed by flanging the end portion of the silicon thin film 120 with the screw B between the first flange 111 and the second flange 112. Here, the flange-coupled hermetically sealing method is one embodiment for convenience of explanation, and various sealing methods other than the above-described sealing method can be applied.

When the body cutting portion is inserted into the sealed liner 100 which is completely sealed in the above-described manner to apply the weight pressure (in the direction of the arrow in Fig. 3), the sealing The silicon thin film 120 is uniformly adhered to and covered with the surface of the recessed portion where the silicon thin film 120 is inserted.

This means that when the pressure is applied to a part of the sealed container filled with fluid, the same pressure acts on the entire inside of the sealed container. Pascal's principle of fluid dynamics is applied.

For reference, the interior of the sealed liner 100 may be filled with air and incompressible liquid appropriately so that there is less variation in volume with pressure.

As described above, the sealing liner 100 according to the present embodiment has a structure in which a cylindrical body 110 having a metal material open at the top and a circular silicon thin film 120 concave downward at the open top thereof are closed, It is possible to relieve the pain effectively when worn with the will, and to induce comfortable walking.

Meanwhile, the conventional liner disclosed in the aforementioned Korean Patent Application No. 10-2008-0133668 described above has a structure in which silicon is inserted between the end of the piercing portion and the hard socket to buffer the weight pressure and impact, that is, The sealing liner 100 of the present embodiment is considerably different in that it utilizes the internal pressure of the closed cylindrical body 110 and the conventional art of the above document can estimate the effect of the present invention none.

According to the sealing liner 100 of the present embodiment having such a structure and an action, the sealing liner 100 has a structure that is easily deformed by the weight pressure (direction of arrow in Fig. 3) and tightly wrapped around the end surface of the trunk cutting portion, It is possible to induce comfortable walking without causing pain.

And the surface of the recessed cut portion inserted into the sealing liner 100 of the present embodiment is subjected to even pressure. Even pressure is applied to the irregular shape of the end of the truncated portion.

Therefore, inconveniences such as scratches, pain, and the like, which are caused by being concentrated on the end portions of the truncated conical part, can be solved.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
