Technical Field

[0001] The utility model relates to the technical field of medical nursing auxiliary equipment, in particular to a ventricular drainage bag fixing device. Background Art

[0002] After brain surgery, the patient's head needs to use a closed drainage device to reduce meningeal irritation, relieve intracranial pressure and promote infection control. The ventricular drainage bottle should be hung at the head of the bed, and the opening of the drainage tube should be 10-15 cm above the plane of the patient's lateral ventricle to maintain normal intracranial pressure. If the drainage tube is too high, it may lead to poor drainage; if it is too low, it may cause problems such as excessive drainage. In the process of caring for patients with craniocerebral injury, medical staff need to pay attention to adjusting the height of the head of the bed, and adjust the height of the drainage tube in time when the height of the head of the bed changes. Failure to adjust in time may result in adverse consequences. At present, the structure of the adjustment frame on the market is relatively simple and is installed at the head of the bed. As the head of the bed tilts, it is difficult to adapt to changes in the relative position of the patient. Therefore, there are major safety hazards and large errors during adjustment.
