Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a lumbar cistern drainage bracket device. Background Art

[0002] Lumbar drainage is a commonly used clinical treatment method in which a soft tube is placed in the patient's subarachnoid space after lumbar puncture, and then the patient's cerebrospinal fluid is drained out of the body to reduce the patient's intracranial pressure. The drainage kit used mainly includes: a lumbar drainage tube, an external tube, a drainage bottle and a drainage bag. In order to ensure the patient's personal safety and treatment effect, the drainage speed of the patient's cerebrospinal fluid should be strictly controlled. The usual way to control the drainage speed is to manually adjust the height of the drainage bottle on the infusion stand. Once the patient's position changes, in order to maintain the intracranial pressure at a normal level, the height of the drainage bottle needs to be readjusted, which consumes the energy and physical strength of the nursing staff. Most of the existing technologies adjust the height of the drainage bottle manually. When the medical staff is working on their hands and needs to adjust the height of the drainage bottle at the same time, two medical staff are required to complete it, which increases the workload of the medical staff. Therefore, there is an urgent need for a lumbar drainage bracket that can not only perform manual operations at the same time, but also adjust the height of the drainage bottle.
