Detailed description of the invention
Below provide specific embodiment of the utility model, it should be noted that this utility model is not limited to following specific embodiment, all equivalents done on technical scheme basis all fall into protection domain of the present utility model.
Embodiment:
Defer to technique scheme, as shown in Figure 1, the present embodiment provides a kind of drainage of cerebrospinal fluid device that drainage tube can be kept unimpeded, comprises drainage tube 1, drainage tube 1 is provided with the motor peristaltic pump 2 that extruding drainage tube 1 eliminates clot;
Drainage tube 1 is communicated with the first flexible pipe 3, first flexible pipe 3 and is communicated with one end of inverted U pipe 4 on the position of patient's cranial cavity, and the other end of inverted U pipe 4 is communicated with one end of U-shaped pressure reduction pipe 6 by the second flexible pipe 5, and the other end of U-shaped pressure reduction pipe 6 is communicated with air;
Inverted U pipe 4 directly enters in U-shaped pressure reduction pipe 6 for the cerebrospinal fluid intercepted in drainage tube 1, and U-shaped pressure reduction pipe 6, built with indicator solution 7, is used to indicate the pressure in drainage tube 1.
Described indicator solution 7 is conducting liquid, the first wire 8 with indicator solution 7 conducting is drawn bottom U-shaped pressure reduction pipe 6, the second wire 9 has from inside to outside been drawn in the side that U-shaped pressure reduction pipe 6 is communicated with air, when in drainage tube 1 during pressure increase, indicator solution 7 in U-shaped pressure reduction pipe 6 rises on the side be communicated with air, by the first wire 8 and the second wire 9 conducting when rising to the second wire 9 position, power supply 10 is powered, the start and stop of control step motor creeping pump 2 for peristaltic pump stepping motor control circuit 11.
It should be noted that the peristaltic pump stepping motor control circuit 11 described in the present embodiment is the control circuit of this area routine, circuit diagram as shown in Figures 2 to 4, specifically see " analytical tool " fourth phase in 2002, the article that Ben Hong is strange etc. delivers, themes as: peristaltic pump stepping motor control circuit.
