The utility model discloses a nerve reflex examination assistant device, which comprises a bed body, a headrest embedded at the head of the bed body, a bracket arranged transversely on the bed body, a screw connected with the middle thread of the upper transverse beam of the bracket, a pressing plate articulated at the lower end of the screw, and a bracket sliding connected with the bracket through a sliding chute. The bracket is connected with a rotating shaft through a bearing, and a reel wheel is fixed on the rotating shaft. The wheel is connected with the lifting lug on the head pillow by a pulling rope, and a dynamometer is connected on the pulling rope. The two ends of the bracket are fixed with sliders, and the bracket slides through the sliders to connect the bed body. This kind of nerve reflex examination assistant fixes the patient's chest by rotating screw and using dynamometer to measure the resistance of passive neck flexion, so as to judge the degree of neck stiffness more intuitively, reduce the experience requirement of the examiner, slide connection between the scaffold and the bed, and the height of the pressure plate can be adjusted, which is convenient for patients with different body types.

技术介绍
神经反射检查包括浅反射检查、深反射检查、病理反射检查和脑膜刺激征检查,其中脑膜刺激征为脑膜受激惹的体征,见于脑膜炎、蛛网膜下腔出血以及颅压增高等,常见症状比如:颈强直、克尼格征和Brudzinski征。其中颈强直指由于支配颈部肌群的神经受到刺激后,引起颈部肌肉发生痉挛性收缩和疼痛,颈部僵直,活动受限,被动屈曲颈部时有阻抗感,下颌不能贴近胸部。颈项强直是脑膜刺激征中重要的客观体征,主要表现为不同程度的肌强直,尤其是伸肌,头前屈明显受限,即被动屈颈遇到阻力,头侧弯也受到一定的限制,头旋转运动受限较轻,头后仰无强直表现。由于颅后窝处的脑膜受到刺激,进而累及颈髓1~4及相应的颈神经根,使其支配的颈部深层肌肉、斜方肌和胸锁乳突肌过度紧张挛缩。多见于各种脑膜炎或脑膜刺激性病变,如脑膜炎、蛛网膜下腔出血等。还可见于颅内压增高、颅后窝病变、破伤风、颈部疾患,如颈椎病、结核、外伤、畸形等。治疗应找到引起颈项强直的原发疾病,针对病因进行治疗。在进行颈强直检查判断时,患者采取仰卧,检查者 ...
