Abstract
The utility model relates to an external ventricular drainage device. The ventricular external drainage device comprises a puncture catheter, an upper drainage tube, a dropping funnel, a lower drainage tube and a liquid storage bag, wherein the puncture catheter, the upper drainage tube, the dropping funnel, the lower drainage tube and the liquid storage bag are sequentially connected, and a fine-adjustment type flow regulator is arranged on the periphery of the drainage tube. The utility model provides an outdoor drainage ware of brain through set up fine-tuning flow regulator in the drainage tube periphery, can realize the accurate control of cerebrospinal fluid flow, has effectively solved the problem that current traditional wheel clamp can not the accurate control cerebrospinal fluid flow, has compensatied the defect that current cerebral surgery drainage ware can not the accurate control cerebrospinal fluid flow.
Description
Technical Field
The utility model relates to the field of medical equipment, especially, relate to an external ventricular drainage device.
Background
The ventricular external drainage device is used as a medical instrument commonly used in brain surgery, and when the intracranial pressure of the head of a human body is increased due to factors such as cerebrospinal fluid circulation obstruction, cerebral hemorrhage, cerebral abscess, intracranial infection and the like, the ventricular or focus external drainage is usually required to relieve symptoms or treat the symptoms. The total amount of adult cerebrospinal fluid is 130-150 ml, the amount of cerebrospinal fluid generated per day is about 400-500 ml, namely about 16.67-20.83 ml per hour; generally, the drainage quantity of cerebrospinal fluid is required to be controlled to be about 150-350 ml per day, which is about 6.25-14.58 ml/h, and the drainage process is required to be uniform, so that intracranial pressure fluctuation caused by too fast or too slow drainage is avoided. The flow regulating device that current ventricular drainage device used is traditional infusion wheel clamp, and the regulation and the control of dripping the speed need rely on artifical count completely, and in addition, along with the change of patient's clinostatism, the speed of dripping also can change thereupon. In conclusion, the existing drainage device outside the cerebral ventricle cannot meet the requirement of uniform drainage of 6.25-14.58 ml/h of cerebrospinal fluid.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides an external ventricular drainage device, the technical scheme of taking as follows:
the utility model provides an outdoor drainage ware of brain, outdoor drainage ware of brain includes puncture pipe, upper drainage tube, drip chamber, lower drainage tube and stock solution bag, puncture pipe, upper drainage tube, drip chamber, lower drainage tube and stock solution bag connect gradually in proper order, the drainage tube periphery is provided with fine-tuning flow regulator.
Further, the fine-tuning type flow regulator is a rotary type flow regulator.
Further, the dropping speed range of the rotary flow regulator is 100-.
Further, the rotary type flow regulator is disposed at an outer periphery of the upper drainage tube.
Preferably, the outer surface of the liquid storage bag is provided with volume scales, so that the volume parameters of cerebrospinal fluid in the liquid storage bag can be conveniently read.
Preferably, the outer surface of the liquid storage bag is provided with an isolation layer, so that liquid in the liquid storage bag can be effectively prevented from being irradiated by light.
Preferably, the outer surface of the dropping funnel is provided with volume scales, so that the volume of liquid in the dropping funnel can be read conveniently.
Due to the implementation of the above technical scheme, compared with the prior art, the utility model have the following advantage:
the utility model provides an outdoor drainage ware of brain through set up fine-tuning flow regulator in the drainage tube periphery, can realize the accurate control of cerebrospinal fluid flow, has effectively solved the problem that current traditional wheel clamp can not carry out the accurate control cerebrospinal fluid flow, has compensatied the defect that current cerebral surgery drainage ware can not the accurate control cerebrospinal fluid flow.
