Description

The utility model relates to the field of medical technology, namely to prosthetics and prosthetics, and is designed to control a pair oar in rowing boats, for example, the PR3mix2x class.

A known power prosthesis of the forearm for sports, containing a movable and fixed half-rings - "lips", a return spring, a clamping screw, a swing axis, a power bushing, a bracket, an elastic element, a fixing screw, a power cup and a receiving sleeve (RF patent for invention No. 2108072).

The disadvantage of the known power prosthesis is the structural complexity of the manufacturing technology, hence the high cost, as well as the impossibility of applying to different sizes of the user's forearm.

The task at which the proposed solution is directed is to simplify the prosthesis manufacturing technology, reduce its cost and expand the applicability to different sizes of the user's forearm.

The technical result is achieved by the fact that in the power prosthesis of the forearm for controlling a pair oar in rowing boats, containing a fixed and movable half-rings - "lips", a receiving sleeve, a power glass, on the fixed half-ring there is a hinged eccentric clamp providing connection with a movable half-ring on its mounting platform with a slot, and the eccentric clamp is made with the ability to rotate and extend it from the slot, while the power cup, pivotally connected to the half rings, is made in the form of a plate with a stop angle on which an elastic gasket is installed, and the receiving sleeve is made with the ability attachment to the plate, and the receiving sleeve is made in the form of a cuff made of durable fabric with fixing and pressure bands.

The technical result is illustrated by drawings, where Fig. 1 shows the appearance of a power prosthesis of the forearm for controlling a pair oar in rowing boats;

fig. 2. - the appearance of half rings - "lips" with an eccentric clamp.

A power prosthesis of the forearm for controlling a pair of oars in boats for rowing, contains a power cup 1 in the form of a plate with a stop angle 2, with an elastic pad 9 installed on it. A fixed semicircle - "lip" 5 and a movable semi-ring-"lip" 6, while on the stationary semi-ring-"lip" 5, an eccentric clamp 7 is hingedly mounted, and on the other side of the power glass 1 is attached a receiving sleeve made in the form of a cuff 3 made of strong fabric with a fixing tape 4 and a clamping tape 8 with latch 10.

The principle of using a power prosthesis of the forearm to control a pair of oars in rowing boats is as follows: the lower part of one third of the forearm is placed in a receptacle in the form of a cuff 3 and is fixed with a tape 4, after which a pressure tape 8 with a retainer 10 is pressed more tightly against an elastic pad 9 located on the stop angle 2. Next, the movable half-ring-“lip” 6 opens and the handle of the oar is laid inside the fixed half-ring-“lip” 5. Then the movable half-ring “lip” 6 is closed and the eccentric clamp 7 tightens the half-rings “lips”, rigidly fixing the handle of the oar. The athlete can start to work with an oar, while the articulated connection of the power cup 1 and the half-rings - "lips" 5 and 6, provides the necessary swing angle of the oar, and the eccentric clamp 7 allows you to quickly release the oar handle in an emergency by turning the eccentric clamp and pushing it out of the slot ...
