Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, and more specifically, to an intracranial pressure monitoring and drainage management device. Background Art

[0002] It is known that in the clinical treatment of the intensive care unit (ICU) of a hospital, nutrient solutions or medicinal liquids required by the human body are often infused into patients; among them, due to the obvious difference between the environment where the human brain is located and the external environment, there is a certain pressure in the skull; if medicinal liquid is infused into the cerebral ventricle for treating the brain, the intracranial pressure will increase; if cerebrospinal fluid is appropriately drained to keep the intracranial pressure stable, excessive drainage will reduce the intracranial pressure; and too high or too low intracranial pressure will affect the actual infusion speed, and thus affect the treatment effect; in view of this situation, the existing method often combines a traction rope and a high-point hook, and knots are tied at different positions on the traction rope to pull the drainage bottle to different heights, so as to adjust the height of the drainage bottle, and the input speed of the drainage bottle is adjusted by gravity, so that the intracranial pressure is stable and medicinal liquid enters the cerebral ventricle for treatment.

[0003] However, in actual use, since the intracranial pressure is prone to fluctuate and change, and it will change accordingly with the movement of the human body, especially the height change. In the existing technology, the intracranial pressure is often detected and the drainage is managed separately, and there is a lack of drainage management measures for synchronous lifting and lowering adjustment in response to the change of intracranial pressure, which is time-consuming, laborious and inefficient. Therefore, the utility model proposes an intracranial pressure monitoring and drainage management device as a further improvement. Summary of the Utility Model
