Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a calf prosthesis sleeve. Background Art

[0002] At present, people with lower leg disabilities can be treated with prosthetic covers. However, the disadvantage is that there is a large friction between the prosthetic cover and the residual limb, which will cause itching or even ulceration in the prosthetic cover, seriously affecting the health of the disabled. The existing prosthetic covers are made of too hard materials, are not comfortable to use, and have no warmth-retaining effect in cold weather. Utility Model Content

[0003] In view of this, in order to solve the problems existing in the technical background, the utility model proposes a calf prosthesis sleeve, and the specific technical solution is as follows:

[0004] A calf prosthesis sleeve comprises a sleeve body, a connector is provided at the bottom of the sleeve body, an exhaust valve is provided on the side wall of the sleeve body close to the bottom surface, and the sleeve body comprises a polyester fabric layer, a reinforcement layer, a thermal insulation fabric layer and an elastic layer from the inside to the outside.

[0005] Furthermore, the top side wall of the sleeve is provided with an adjustment mechanism for adjusting the size of the opening at the top of the sleeve, and the adjustment mechanism comprises a rubber sheet on which a plurality of rows of buckles and a row of hooks are arranged.

[0006] Furthermore, the reinforcement layer is made of textile cloth.

[0007] Furthermore, the thermal insulation fabric layer is made of thermal insulation cotton.

[0008] Furthermore, the elastic layer is made of gel material.

[0009] Furthermore, the thickness of the gel is 2-3 mm.

[0010] The above technical solution has the following beneficial effects:

[0011] The utility model has a simple structure and good practicality. The sleeve body is composited with a polyester fabric layer, a reinforcement layer, a thermal insulation fabric layer and an elastic layer. It is not easy to get loose and has good elasticity. The arranged adjustment mechanism can facilitate the adjustment of the size of the sleeve opening. The sleeve body fits closely to the skin, is comfortable to wear, has good air permeability, and has a thermal insulation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] Example 1: Figure 1-3 A calf prosthesis sleeve shown includes a sleeve body 1, a connector 2 is provided at the bottom of the sleeve body 1, an exhaust valve 3 is provided on the side wall of the sleeve body 1 close to the bottom surface, and the sleeve body 1 comprises a polyester fabric layer 11, a reinforcement layer 12, a thermal insulation fabric layer 13 and an elastic layer 14 from the inside to the outside.

[0020] The top side wall of the sleeve body 1 is provided with an adjustment mechanism for adjusting the size of the opening at the top of the sleeve body 1 . The adjustment mechanism comprises a rubber sheet on which a plurality of rows of buckles 41 and a row of hooks 42 are arranged.

[0021] The reinforcing layer 12 is made of textile cloth, the thermal insulation fabric layer 13 is made of thermal insulation cotton, and the elastic layer 14 is made of gel, and the thickness of the gel is 2-3 mm.

[0022] Open the exhaust valve 3, put the sleeve 1 into the lower limb, adjust the adjustment mechanism to make it fit the human skin, which is convenient for different people to use, so that the prosthesis sleeve body can be worn firmly and more comfortable. After wearing, close the exhaust valve 3.

[0023] The utility model has a simple structure and good practicality. The sleeve body 1 is composited with a polyester fabric layer 11, a reinforcement layer 12, a thermal insulation fabric layer 13 and an elastic layer 14. It is not easy to get loose and has good elasticity. The arranged adjustment mechanism 4 can facilitate the adjustment of the size of the opening of the sleeve body 1. The sleeve body 1 fits tightly to the skin, is comfortable to wear, has good air permeability, and has a thermal insulation effect.
