Description

一种康复用握力计 技术领域
本发明属于康复医疗器械技术领域，具体涉及一种康复用握力计。
背景技术
握力计常见于握力锻炼及康复训练等领域，通过弹性材料(橡胶、硅胶等)或弹簧等机械结构实现其功能。带有力度指示的该类产品根据使用场景不同，可显示抓握次数，也可显示抓握力度，一般通过紧握握力记握把使其产生明显的机械形变后获得次数及力度数据。握力显著下降的使用者，如中风病患等，难以握紧带有机械结构的握力计；弹性材料类康复用握力计(握力球)便于抓握，但无法对极微弱的握力进行指示以了解恢复程度或显著缩短恢复所用时间。因此，此类病患在恢复初期无法正常使用已存在的握力计设备进行有效的康复训练。
发明内容
本发明要解决的技术问题是：克服现有技术的不足，提供一种易抓握、高精度、高灵敏度的康复用握力计，用于中风等疾病或外伤造成握力显著下降的病患出院后的握力康复训练及恢复，结合电刺激技术缩短恢复所用时间。
本发明解决其技术问题所采用的技术方案是：一种康复用握力计，包括一壳体、一握力计本体，其特征在于：所述壳体包括左、右外壳，所述左、右外壳卡合在所述握力计本体的表面；所述左、右外壳的内表面上均设置有凸起的受力柱；所述握力计本体包括一主控板、一充电接口板，所述主控板设置在所述充电接口板上方；所述主控板的下方还设置一电池、一压力传感器；所述充电接口板上设置一充电接口；所述主控板的上部，设置有第一LED显示灯；所述受力柱与所述压力传感器相抵靠；所述主控板分别与所述电池、所述压力传感器、所述充电接口、所述第一LED显示灯进行电连接；所述充电接口可通过所述主控板中的电源管理芯片对所述电池充电；还包括一高速扁圆震动马达，所述高速扁圆震动马达设置在所述电池旁，且与所述主控板电连接。
优选的，所述握力计本体还包括一底板；所述底板设置在所述充电接口板下方，所述电池、所述压力传感器、所述充电接口设置在所述主控板与所述底板之间。

优选的，所述底板的底部中间位置，纵向设置有第二LED显示灯；所述第二LED显示灯与所述主控板进行电连接。
优选的，所述压力传感器为薄膜压力传感器。
优选的，所述受力柱与所述薄膜压力传感器之间设置有一硬橡胶垫。
优选的，所述第一LED显示灯为若干个，且纵向组成一排，设置于所述主控板的上表面中部，所述左、右外壳的结合部；所述第一LED显示灯上方设置有一导光带，所述导光带覆盖在所述第一LED显示灯上方；所述第二LED显示灯为若干个，且纵向组成一排，设置于所述底板的下表面中部，所述左、右外壳的结合部；所述导光带覆盖在所述第二LED显示灯的下方。
优选的，所述受力柱对称设置在所述左、右外壳的内表面上。
