Title: Apparatus for re-placing slipped discs
IPC: A61H1/00
Filed: 1982-08-31
Abstract: The invention relates to the field of health; it is capable of providing relief to persons who are suffering from slipped discs. In addition to the frame consisting of four vertical uprights 1 and a number of crosspieces 5, the apparatus comprises four essential pieces: a vertical board against which the back is pressed; at mid-height, two horizontal bars for supporting the hands; and, right at the bottom, a horizontal support for supporting the feet. By virtue of these support points for the hands and for the feet, the user can guide the movements of the back and find the force desired for re-placing the discs.

Patent FR-2567760-A1 (FR)
IPC: A61M5/315
Filed: 1984-07-18
Abstract: The apparatus is of the type comprising a frame (1) having the general shape of a gun provided with a grip (2) and receiving a moving carriage (5) for a removable syringe (31) with needle (33) and piston (34). It is characterized in that it is fitted with a single drive element, here a fluid distributor (12-13), connected only to a pusher (7) held bearing against the piston (34) of the syringe. The kinematic connection is of the one way type. The carriage (5) is associated to a fixed stop (25) at a distance (D1) shorter that the possible total stroke (D2) of the slide (13). Thus, in the back-to-front direction, the driven pusher (7) pushes the piston (34)-syringe (31)-carriage (5) assembly by bearing on the product (A) held in the syringe. When the carriage (5) meets the stop (25) it is stopped and the syringe (31) is motionless, but the pusher (7) continues its stroke and forces the product (A) to flow through the needle (33). In the front-to-back direction, a rod (10) integral with the slide (13) brings back the carriage (5) by a stop (14) which is arranged thereon and this motion drives the syringe (31)-piston (34)-pusher (7) (the latter being now free) assembly to go simultaneously backwards. The carriage and the syringe (31) are back to their starting position while the piston (34) moves back to a slightly shorter distance which is function of the dose of product (A) pushed by said piston during the preceding back-to-front stroke.
