Further, described spring force value is normal human's ventricles of the brain Pressure maximum value.
The beneficial effects of the utility model are:
1, this utility model is in the middle part of drainage tube, arrange a pressure control valve, by the keying of the pressure control valve of cerebrospinal fluid, when cerebrospinal pressure force value is higher than pressure control valve preset pressure, pressure control valve is opened automatically, and cerebrospinal fluid enters abdominal cavity of patients and absorbed, and patient's Intraventricular cerebrospinal fluid reduces, ventricles of the brain pressure gets back to normal level, pressure-control valve, according to patient's ventricles of the brain pressure automatic open close, regulates patient's Intraventricular pressure in real time, ensures patient safety.
2, simple, easy to use, with low cost, the patient's ventricles of the brain pressure of this utility model structure regulates automatically, medical personnel directly do not contact this utility model, avoid cross infection, can effectively reduce medical personnel's labor intensity, increase work efficiency, ensure drainage effect simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of pressure-control valve of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, a kind of pressure control ventricular drainage pipe, comprise ventricles of the brain connection tube 1, abdominal cavity connection tube 2 and pressure-control valve 3, one end of described ventricles of the brain connection tube 1 connects patient's ventricles of the brain, the inlet 9 of its other end Bonding pressure control valve 3, ventricles of the brain connection tube 1 between the described ventricles of the brain and pressure-control valve 3 is provided with check valve 4, pressure-control valve 3 comprises valve body 5, inlet 9, liquid outlet 10, spring 7, piston 8 and spool 6, spool 6 is provided with in described valve body 5, it is flow channel for liquids 12 between valve body 5 and spool 6, spool 6 is hollow structure, described inlet 9 is communicated with spool 6 inner chamber, piston 8 is provided with in described spool 6, spring 7 is provided with between piston 8 and spool 6 inner bottom surface, described valve body 5 lower end arranges liquid outlet 10, liquid outlet 10 is communicated with flow channel for liquids 12, described spool 6 sidewall is provided with connector 11, connector 11 is communicated with spool 6 inner chamber and flow channel for liquids 12, under spring 7 normal condition, piston 8 shutoff connector 11, described spring 7 value of elastic is normal human's ventricles of the brain Pressure maximum value.The liquid outlet 10 of described pressure-control valve 3 connects one end of abdominal cavity connection tube 2, and the other end of abdominal cavity connection tube 2 connects abdominal cavity of patients.Described ventricles of the brain connection tube 1 and abdominal cavity connection tube 2 are medical silicone tube.
During use, cerebrospinal fluid stockpiles in patient's Intraventricular, because ventricles of the brain connection tube 1 is communicated with patient's ventricles of the brain and pressure-control valve 3, therefore, the pressure that pressure-control valve 3 goes out is identical with patient's ventricles of the brain pressure, when Intraventricular because the too much build-up of pressure of cerebrospinal fluid raises, and force value is when exceeding human normal ventricles of the brain pressure limit, now, the pressure that cerebrospinal fluid is applied to piston 8 is greater than the elastic force of spring 7, then cerebrospinal fluid promotion piston 8 moves down, after piston 8 height is lower than connector 11 height, spool 6 inner chamber is communicated with flow channel for liquids 12, cerebrospinal fluid enters flow channel for liquids 12 from connector 11, then flow out from liquid outlet 10, abdominal cavity of patients is entered through abdominal cavity connection tube 2, absorbed at intraperitoneal cerebrospinal fluid.
Patient's Intraventricular cerebrospinal fluid reduces, and ventricles of the brain pressure reduces, then piston 8 resets under the effect of spring 7 counter-force, and connector 11 is closed, and ventricles of the brain connection tube 1 and abdominal cavity connection tube 2 disconnect.
