Изобретение относитс к медицинской технике, а именно к протезированию и протезостроению .The invention relates to medical technology, namely to prosthetics and prostatic engineering.
Цель изобретени - сохранение целостности негатива при извлечении из него культи .The purpose of the invention is to preserve the integrity of the negative while removing the stump from it.
Способ осуществл ют следующим образом .The method is carried out as follows.
Емкость с двойными стенками и двойным дном, внутренн поверхность которой выполнена с перфораци ми и покрыта воздухопроницаемой прокладкой, выполненной, например, из войлока, частично выполн ют формовочным материлом, например песком. Устанавливают культю инвалида с одетым на нее воздухонепроницаемым чехлом, например , из полиэтиленовой пленки с запасом материала по периметру в верхней его части. Инвалида при нагруженной культе или больного с деформаци ми стоп устанавливают таким образом, чтобы он не испытывал болезненных ощущений. В таком положении емкость наполн ют формовочным материалом , отгибают к кра м емкости чехол, обеспечива герметичность их контакта, и подключают емкость к вакуумному насосу. Отсасыва газ из формовочного материала, создают разрежение, например, до 0,7 ата. Под действием разности давлений формовочный материал резко упрочн етс , формаA double-walled and double-bottom container, the inner surface of which is perforated and covered with an air-permeable pad made, for example, of felt, is partly made with a molding material such as sand. Install the stump of a disabled person with an airtight cover dressed on it, for example, from a polyethylene film with a margin of material around the perimeter in its upper part. A disabled person with a loaded cult or a patient with deformities of the feet is installed in such a way that he does not experience painful sensations. In this position, the container is filled with molding material, the cover is bent to the edges of the container, ensuring the tightness of their contact, and the container is connected to the vacuum pump. Suction gas from the molding material, create a vacuum, for example, to 0.7 at. Under the action of the pressure difference, the molding material is sharply strengthened, the shape
становитс жесткой. После этого культю извлекают без полиэтиленового чехла, провод т многократные примерки и корректировку внутренней формы, ориентиру сь на индивидуальные ощущени инвалида.becomes tough. After this, the stump is removed without a polyethylene cover, repeated fittings and adjustment of the inner shape are carried out, focusing on the individual sensations of the disabled person.
Полученную форму-негатив заливают, например, гипсовой смесью. После застывани смеси вакуумный насос отключают. Форма-негатив разрущаетс , так как формовочный материал обретает исходное состо ние . Полученные анатомические модели используютс дл изготовлени изделий, например приемной гильзы протеза, моделей опорной области стоп нижних конечностей.The resulting negative form is filled, for example, with a plaster mix. After the mixture has hardened, the vacuum pump is turned off. The negative form is destroyed, as the molding material acquires the initial state. The anatomical models obtained are used to make products, for example, a prosthesis liner, models of the supporting region of the feet of the lower limbs.
Дл обеспечени нужной прочности формы достаточно создать разрежение 0,6- 0,8 ата. Это разрежение не оказывает болезненных воздействий на м гкие ткани мо делируемой культи.To provide the required form strength, it is sufficient to create a negative pressure of 0.6-0.8 at. This rarefaction does not affect the soft tissues of the simulated stump.
Таким образом,- при извлечении культи из формы-негатива, эта форма не разруща0 етс и может быть многократно использована дл примерок. При необходимости, если имеютс болезненные ощущени , рельеф модели можно скорректировать.Thus, when extracting a stump from a negative form, this form is not destroyed and can be reused for fitting. If necessary, if there is pain, the relief of the model can be adjusted.
Способ отличаетс простотой, точностью изготовлени анатомических моделей, позвол ет многократно использовать дешевый формовочный материал, что особенно выгодно в индивидуальном производстве анатомических моделей сложной формы.The method is characterized by simplicity and precision in the manufacture of anatomical models, and it allows reusing cheap molding material, which is particularly advantageous in the individual production of anatomical models of complex shape.
