Problems solved by technology

Difficulty adjusting the angle and direction will cause the gravity on the arm to be unable to be balanced and adjusted during training. It is not flexible enough to use, and it also makes the patient's physical exertion serious and easy to feel fatigued.
In addition, if the force is not well balanced during training, it is prone to various uncontrollable free swings, which will lead to unpredictable falling injuries of the patient or damage to other surrounding objects by touching, which cannot meet the rehabilitation treatment that needs to adjust the angle of the arm. Therefore, urgently need those skilled in the art to design a kind of novel arm support structure

Abstract

The invention discloses an adjustable upper limb arm bracket. The arm bracket comprises a fixed seat component, a three connecting lever component, an adjustable lever component and a bracket component, wherein the three connecting lever component is arranged on the upper end of the fixed seat component and is rotatably connected with the fixed seat component; the adjustable lever component is arranged on the upper end of the three connecting lever component and is rotatably connected with the three connecting lever component; the bracket component is arranged on the upper end of the adjustable lever component and is rotatably connected with the adjustable lever component; and the adjustable lever component comprises a secondary fixed rod, a lever seat, a pull rod, a pull ring and a lever;the secondary fixed rod is fixed in the lever seat; the lever is arranged on the upper end of the lever seat; the pull rod is arranged on one end of the lever; the lever seat and the lever, the leverand the pull rod and the pull rod and the pull ring are respectively connected by secondary hinge pins; tertiary bearings sleeve on the secondary hinge pins; and the pull ring and the lever seat arefixedly connected by a bayonet. The arm bracket disclosed by the invention has the beneficial effects that the angle and the direction can be adjusted to balance the gravity force on an arm during training; the arm bracket is very flexible in use and high in structural strength; and the comfort feeling of a patient in rehabilitation training is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a height-adjustable arm support suitable for rehabilitation treatment. Background technique [0002] The current conventional arm support is only a simple support, the range of motion is small, and the height cannot be adjusted. Difficulty adjusting the angle and direction will lead to the inability to balance the gravity on the arms during training, and the use is not flexible enough, which also makes the patient's physical exertion serious and easy to feel fatigued. In addition, if the force is not well balanced during training, various uncontrollable free swings will easily occur, which will lead to unpredictable falling injuries of the patient or damage to other surrounding objects by touching, which cannot meet the rehabilitation treatment that needs to adjust the arm angle. Therefore, those skilled in the art are badly in need of designing a novel arm support struc...
