使用装置时，将穿刺针6穿刺后，脑脊液通过穿刺针6流向连接管5内，测压表4对压力进行检测，当压力值位于设定范围内时，控制电磁阀26打开，脑脊液进入脑脊液存储罐21内，当压力值低于设定范围(当压力小于80mm水柱)时或放液量达到40mL，控制电磁阀26关闭，脑脊液无法继续放液；此时，此时控制泵34打开，将盐水存储罐31内的生理盐水注射如患者体内；脑脊液存储罐21和盐水存储罐31规格相同，放液装置2的第一液位传感器23记录脑脊液放出容量，注射装置3的第二液位传感器33记录生理盐水注射容量，当盐水存储罐31内生理盐水液位的下降高度等于的脑脊液存储罐21内存储的脑脊液液位高度时，泵34停止工作。此时，将穿刺针6从患者体内拔出即；可当压力值超出设定范围(当压力大于500mm水柱)时，控制电磁阀26关闭，脑脊液无法放液，泵34不工作。When using the device, after the puncture needle 6 is punctured, the cerebrospinal fluid flows into the connecting tube 5 through the puncture needle 6, and the pressure gauge 4 detects the pressure. When the pressure value is within the set range, the solenoid valve 26 is controlled to open, and the cerebrospinal fluid enters the cerebrospinal fluid In the storage tank 21, when the pressure value is lower than the set range (when the pressure is less than 80mm water column) or the discharge volume reaches 40mL, the control solenoid valve 26 is closed, and the cerebrospinal fluid cannot continue to discharge; at this time, the control pump 34 is opened at this time, The physiological saline in the saline storage tank 31 is injected into the patient's body; the specifications of the cerebrospinal fluid storage tank 21 and the saline storage tank 31 are the same, the first liquid level sensor 23 of the liquid discharging device 2 records the discharge capacity of the cerebrospinal fluid, and the second liquid level of the injection device 3 The sensor 33 records the injection volume of physiological saline, and when the drop height of the physiological saline level in the saline storage tank 31 is equal to the cerebrospinal fluid level stored in the cerebrospinal fluid storage tank 21 , the pump 34 stops working. Now, the puncture needle 6 is pulled out from the patient's body; but when the pressure value exceeds the set range (when the pressure is greater than 500mm water column), the control solenoid valve 26 is closed, the cerebrospinal fluid cannot be drained, and the pump 34 does not work.
通过测压表4的设置对压力进行实时检测和监控，脑脊液的放液更精准安全；脑脊液的置换过程自动进行，放液注射效率高，不易出现渗漏，能对患者进行更好的保护，更加安全可靠；通过第一液位传感器23和第二液位传感器33的设置对液面高度进行检测监控，自动平衡脑脊液的放液量和生理盐水的注射量，脑脊液置换效果好。Real-time detection and monitoring of the pressure through the setting of the pressure gauge 4, the discharge of the cerebrospinal fluid is more accurate and safe; the replacement process of the cerebrospinal fluid is carried out automatically, the injection efficiency of the discharge is high, and leakage is not easy to occur, which can better protect the patient. It is safer and more reliable; through the setting of the first liquid level sensor 23 and the second liquid level sensor 33, the liquid level is monitored and monitored, and the amount of cerebrospinal fluid released and the amount of saline injected are automatically balanced, and the effect of cerebrospinal fluid replacement is good.
装置使用后可进行拆解，连接管5、穿刺针6部分不易清理且成本较低，作为一次性用品；控制台1、放液装置2、注射装置3和测压表4不与患者直接接触且成本较高，清理消毒后可继续使用，从而有效降低装置的使用成本。The device can be disassembled after use, the connecting tube 5 and the puncture needle 6 are not easy to clean and the cost is low, and they are used as disposable items; the console 1, the liquid discharge device 2, the injection device 3 and the pressure gauge 4 are not in direct contact with the patient And the cost is relatively high, and it can continue to be used after cleaning and disinfection, thereby effectively reducing the use cost of the device.
