The white light passes through the exudate.
点光源 10优选为氙气灯， 并在点光源处设置散热片 11 , 从而可给点 光源电路中的镇流器等元件有效散热。 The point light source 10 is preferably a xenon lamp, and a heat sink 11 is disposed at the point source to effectively dissipate heat such as a ballast in the point source circuit.
颜色传感器光室 14内设置有三原色颜色传感器 15 ,优选为 RGB颜色 传感器， 可以定性和 /或定量地获取三原色； 特别地， 在颜色传感器光室 14 入口设置散射片 11 , 在颜色传感器光室内色绘制 IR滤波镜 12, 使接收到 的光线变成均勾柔和， 并均勾分布在三原色颜色传感器 15上。 当点光源 10发出白光时，光线经过连接管 4折射之后到达颜色传感器 光室 14位置； 然后经过散射片 11进入颜色传感器光室 14; 再经过光室内 IR滤镜 12使白光光线变成均勾柔和， 以保证白光光线可以均勾的分布在 颜色传感器 15上。The color sensor light chamber 14 is provided with a three primary color sensor 15, preferably an RGB color sensor, which can acquire the three primary colors qualitatively and/or quantitatively; in particular, a diffusing sheet 11 is provided at the entrance of the color sensor light chamber 14 in the color sensor light chamber The IR filter mirror 12 is drawn to make the received light become soft and evenly distributed on the three primary color sensors 15.

本发明中， 检测控制单元根据伤口渗出液透明度检测模块 9得到的记 录， 计算伤口渗出液的透明度， 其具体运算方法为： 预先测量无渗出液流 过连接管 4时的白光信号值， 并建立伤口渗出液透明度的值与颜色传感器 接收到的白光信号的对应表， 伤口渗出液透明度的值等于有渗出液流经连 接管时与无渗出液流经连接管时所接收到的白光信号值的比。 在建立的对 应表中， 有渗出液流经连接管时与无渗出液流经连接管时所接收到的白光 信号值的比最大值对应透明度最大值 100, 有渗出液流经连接管时与无渗 出液流经连接管时所接收到的白光信号值的比最小值对应透明度最小值 0, 在 0 ~ 100的范围内， 每个数值都与一白光信号值的比例相对应， 根据 有渗出液流经连接管时与无渗出液流经连接管时所接收到的白光信号值的 比即可查找得到相应的伤口渗出液透明度值。 这样， 通过利用接收单元白 光信号值的大小， 这样， 通过获得伤口渗出液透明度的大小， 可为医护人 员对伤口渗出液进行管理、 研究提供方便。 In the present invention, the detection control unit calculates the transparency of the wound exudate according to the record obtained by the wound exudate transparency detecting module 9, and the specific calculation method is: pre-measuring the white light signal value when no exudate flows through the connecting tube 4. And establishing a correspondence table between the value of the transparency of the wound exudate and the white light signal received by the color sensor, and the value of the transparency of the wound exudate is equal to when the exudate flows through the connecting tube and when the non-exuding liquid flows through the connecting tube The ratio of the received white light signal values. In the established correspondence table, the maximum value of the ratio of the white light signal value received when the exudate flows through the connecting pipe and the non-exuding liquid flows through the connecting pipe corresponds to a transparency maximum value of 100, and the exudate flows through the connection. The ratio of the ratio of the white light signal received by the tube and the non-exuding fluid flowing through the connecting tube corresponds to the minimum value of transparency 0. In the range of 0 to 100, each value corresponds to the ratio of the value of a white light signal. According to the ratio of the white light signal value received when the exudate flows through the connecting tube and when the non-exuding liquid flows through the connecting tube, the corresponding wound exudate transparency value can be found. Thus, by utilizing the magnitude of the white light signal value of the receiving unit, by obtaining the transparency of the wound exudate, it is convenient for the medical staff to manage and study the wound exudate.
