The application relates to the technical field of medical devices, in particular to a modular PICC
nursing auxiliary device which comprises a shoulder fixing part, an arm fixing part and an
elbow fixing part which are integrally arranged; the lowest end of the
elbow fixing part is higher than the position of the
elbow, an installation groove is formed in the elbow fixing part, a clamping piece is arranged in the installation groove, an adapter is movably arranged in the installation groove, a bottom limiting piece is rotatably arranged on the adapter, a top limiting piece is inserted into the bottom limiting piece, a plurality of limiting channels are formed between the bottom limiting piece and the top limiting piece and are used for limiting the exposed
catheter. The shoulder fixing part, the arm fixing part and the elbow fixing part are integrally designed, the whole device is adhered to the limbs after being worn, the device is fixedly stable, the device is prevented from being displaced, and the normal movement of the elbow is not limited; the adapter and the limiting piece are independent modules, are convenient to disassemble and assemble, can be quickly replaced and adjusted according to the
nursing requirements; the multiple independent limiting channels separate the exposed
catheter, the
catheter is prevented from being wound, twisted, folded and axially moved, and the risks of
pipe blockage and slipping are reduced.
