Description

TECHNICAL FIELD

[0001] The utility model relates to medical consumable technical field, concretely relates to a ventricular drainage tube height measuring device. BACKGROUND

[0002] External ventricular drainage (EVD) is a common treatment method in neurosurgery, mainly used for treating hydrocephalus, intracranial pressure increase and other diseases. External ventricular drainage inserts a drainage tube into the ventricle to drain excess cerebrospinal fluid to the outside of the body to reduce intracranial pressure and maintain the balance of cerebrospinal fluid circulation. During the drainage process, the height setting of the drainage tube is crucial, as it directly affects the drainage speed and control of intracranial pressure. If the drainage tube height is not set properly, it may lead to excessive or insufficient drainage, causing serious complications such as brain tissue displacement, intracranial hemorrhage or infection.

[0003] Traditional external ventricular drainage tube height adjustment methods usually rely on a horizontal measuring scale or other external measuring tools. Medical staff needs to place the horizontal measuring scale near the patient's head, and manually adjust the height of the drainage tube through visual observation to ensure it is level with the reference point (such as the external ear canal). However, this method has obvious limitations: first, the horizontal measuring scale needs to be carried, increasing the workload of medical staff, especially in emergency situations where it may not be quickly accessible; second, visual observation and manual adjustment are prone to errors, making it difficult to achieve precise height control; finally, the traditional method is cumbersome and time-consuming, which is not conducive to improving nursing efficiency.

[0004] To solve these problems, some improved technologies have been proposed, such as Chinese patent (application number: 201720270048.3) discloses a tool for measuring the height of external ventricular drainage tube placement, which includes an auxiliary piece and a scale piece. The auxiliary piece has a connecting groove in its length direction, the cross section of the connecting groove is "convex", a sliding piece is arranged in the connecting groove, the sliding piece includes a connecting end I and a connecting end II, the connecting end I is arranged in the connecting groove and moves in the connecting groove, the connecting end II extends out from the connecting groove to the outside of the auxiliary piece side, and the scale piece is arranged on the connecting end II outside the auxiliary piece side. The utility model measures conveniently, has high measurement precision, and effectively improves work efficiency.

[0005] However, this device cannot adjust the height of the height measuring scale during use. If the patient's body position changes, the height of the tragus will also change, which requires resetting and calibration, and then adjusting the height of the drainage tube, which will affect the adjustment efficiency and is prone to adjustment errors during the adjustment process.

[0008] As a further improvement of the above technical solution:

[0009] The height adjusting seat includes an adjusting sleeve that moves along the height direction of the extension rod, one side of the adjusting sleeve is provided with a positioning bolt, and the other side is provided with a hinged seat for mounting the level measuring scale.
