Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0040] according to figure 1 The shown drainage device for cerebrospinal fluid leakage after spinal surgery includes a fluid storage bag 1 and a drainage tube 2, one end of the drainage tube 2 is inserted into the inlet of the fluid storage bag 1, and the other end is inserted into the cerebrospinal effusion. A discharge pipe 3 is connected to the bottom of the liquid storage bag 1, and a discharge control valve 4 is installed on the discharge pipe 3. It also includes a hydrometer 5 and a hydrometer box 6 for containing the effusion for specific gravity measurement. The hydrometer 5 is placed in the Inside the specific gravity box 6, the drainage tube 2 is connected to the entrance of the specific gravity box 6 after entering the liquid storage bag 1, and the top of the specific gravity box 6 is provided with an opening and is communicated with...
