TECHNICAL FIELD

[0001] The present application relates to the technical field of medical ventricular drainage tube, in particular to a ventricular drainage tube fixed height measurer. BACKGROUND

[0002] In clinical practice, in order to ensure the safety and effectiveness of ventricular drainage, the drainage tube is generally fixed at a specific position higher than the ventricle by 10-15 cm. For some patients who need to lift the head of the bed by 45° after surgery, precise control of the height of the drainage tube is a key link in the treatment process.

[0003] Ventricular drainage is a common surgical method in neurosurgery, and the fixed height of the drainage tube directly affects the regulation of intracranial pressure. The traditional method uses a simple ruler or visual adjustment of the height, which has large errors, cannot measure the angle, and is inconvenient to fix. In the prior art, some fixing frames can only adjust the height, and the angle of the drainage tube also has an important influence on the drainage efficiency, but there is currently a lack of portable devices that can measure both height and angle.
