Title: Improvements in the manufacture of artificial limbs and other orthopaedic devices
IPC: A61F2/80
Filed: 1930-08-14
Abstract: 367,334. Artificial limbs &c. DESOUTTER BROS., Ltd., 73, Baker Street, London.-(Assignees of Loth, J. ; 28, Bergstrasse, K÷slin, Pommern, Germany.) Aug. 14, 1930, No. 24402. Convention date, Oct. 12, 1929. Void [Published under Sect. 91 of the Acts]. [Class 81 (ii).] In making artificial limbs and other orthopµdic devices the stump is cast and moulded in its normal weighted condition. In the case of a leg, the stump a may first be covered with a piece of hosiery or tricot pipe b, secured in position by a rubber ring c and if necessary also an adhesive strip. The stump is then fitted with a conical cap, preferably also secured in position by an adhesive strip, and thereafter is covered with a plastic mass, for example, of plastic rubber or caoutchouc. At the back part of the leg this dressing may consist of a wide and downwardly tapering plate of caoutchouc covering about one third of the stump, and reinforced by an inside thin perforated plate of light metal. The front part of the stump is also covered with caoutchouc, and further reinforced caoutchouc strips e may be employed longitudinally and circumferentially, as shown in Fig. 2. The stump is now wrapped round with five or six layers of plaster bandage or other gypso-plastic dressing f. When the bandages have hardened the stump is placed under the full weight of the patient upon a block g of adjusted height, the upper part of the caoutchouc covering is wrapped in plaster bandages f<1>, and the contours are worked by hand. When hard, the form is taken off the stump and filled with plaster of Paris. The work piece is then vulcanized, freed from the plaster of Paris and inserted in a funnel of metal, wood, or other suitable material shaped to the form of the limb to be replaced. In some cases the invention may be carried out by placing a metal cone on the stump, and filling the intermediate space with spongy belt or like plastic material soaked in paraffin wax or the like, the patient wearing this device so that the felt hardens under working conditions. From this felt mould a plaster cast is taken, and then caoutchouc is used to form the socket as above described.

The method claimed in the parent Specification is modified in that the condensed oil defining the image on the receiving surface is brought into contact with a copy surface to which at least a proportion of the oil is thereby transferred. In the apparatus of Fig. 1, an original 11 is passed around a translucent drum 1 housing an infra-red heater 3 and reflector 4, an endless band and roller arrangement 5 . . . 8 keeping the original pressed against the drum. During the following revolution of the drum a copy 12 is passed between it and the band. When the original is too long for the peripheral length of the drum, a duplicated heater, reflector and band with rollers arrangement 3<SP>1</SP>. . . 81 is provided through which the copy continuously passes whilst the original is passed through the first arrangement. In the apparatus of Fig. 2 a translucent belt 20 is employed to transfer the markings of the original 25, passing detween the belt and a rotating drum 23, to the copy 30 which is passed over the belt as it moves around a drum 21. An infra-red heater 26 and reflectors 27 heats both drums. The heater 26 may heat the drum 23 only, drum 21 being heated by a heater 31. In a modification of this apparatus the " copy " drum is much larger than the original drum, the band 20 and copy passing around almost the entire circumference of the larger drum. In yet a further embodiment the copy 43, Fig. 4, passes between a drum 45 and the band 20 whilst subjected to pressure from rotating brushes 46. Development of the latent image on the copy is as set out in the parent Specification. The process of the invention may also be carried out manually on a flat bed by the use of successive superimposed sheets.
