Problems solved by technology

[0004] 1. The production process of traditional temporary prostheses is complex, time-consuming and costly
[0005] 2. Existing temporary prostheses that wear local brakes for a long time are likely to cause muscle atrophy, local blood flow is not smooth, and even induce the risk of deep vein thrombosis
[0006] 3. The existing temporary prosthesis is relatively bulky and inconvenient to wear, which may easily cause discomfort to the patient
[0007] 4. The traditional temporary prosthesis does not have armrests, which does not optimize or improve the mobility of patients, and the height is not easy to adjust

Abstract

The invention provides a 3D-printed air bag type temporary prosthesis. The 3D-printed air bag type temporary prosthesis includes a supporting platform, an adjustable upper stabilizing support and an adjustable lower stabilizing support. The upper stabilizing support is arranged on the side of the supporting platform, and the lower stabilizing support is arranged at the bottom of the supporting platform. The upper stabilizing support is provided with a 3D-printed upper leg hoop and a 3D-printed lower leg hoop. Air bags are placed in the upper and lower leg hoods and on the supporting platform.The top of the upper stabilizing support is provided with an outward 3D printed handrail. According to the 3D-printed air bag type temporary prosthesis, an original shell receiving cavity is replacedby a structure in which the adjustable stabilizing supports and the leg hoops with grooves are arranged, so that the wearing process is simplified. A handle on the uppermost portion of the prosthesismay ameliorate the problem of patient mobility inconvenience. The whole structure is simplified, the leg hoops and the handle are manufactured using a 3D printing technology, the adaptability with a patient can be enhanced, the comfort level is improved, and the cost is reduced.

Description

technical field [0001] The present application relates to the technical field of prosthetics, in particular to a 3D printed airbag type temporary prosthesis. Background technique [0002] Usually, temporary prostheses are needed for transition after amputation patients, or temporary prostheses are needed to replace formal prostheses in scenes of small-scale activities such as pouring water, indoor activities, bathing, and getting up at night, so as to achieve quick wear and temporary use function. [0003] However, there are many shortcomings in traditional temporary prostheses: [0004] 1. The production process of traditional temporary prostheses is complex, time-consuming and costly. [0005] 2. Existing temporary prostheses that wear local brakes for a long time are likely to cause muscle atrophy, poor local blood flow, and even induce the risk of deep vein thrombosis. [0006] 3. The existing temporary prosthesis is relatively heavy and inconvenient to wear, which ea...
