An automatic drainage device for intracranial cerebrospinal fluid

Abstract

The invention relates to an automatic drainage device for intracranial cerebrospinal fluid. The device includes a cerebrospinal fluid drainage pipeline, a drainage pump and a reservoir, the drainage pump is connected with the cerebrospinal fluid drainage pipeline, the device is characterized in that the device is provided with an intracranial pressure detection module, an arterial pressure detection module, a flowmeter and a control module, the intracranial pressure detection module and the flowmeter are connected with the cerebrospinal fluid drainage pipeline, the signal output ends of the intracranial pressure detection module and the flowmeter are connected with the control module, the detection is performed on human body arterial pressure by the arterial pressure detection module, thesignal output end of the arterial pressure detection module is connected with the control module, and the output control end of the control module is connected with the drainage pump. The cerebrospinal fluid drainage is controlled by the real time obtained brain perfusion pressure value, the accuracy control is performed on the flow velocity and flow discharge of the drainage, the fine treatment capability aimed at different patients is improved, the more accurate effective treatment can be realized, and the device has better treatment universality for individual difference of conditions; thedevice has advantages of high automation degree and convenient using, the working burden of medical staff is effectively reduced, and the diagnosis and treatment accidents caused by artificial operation faults are avoided.

Description

technical field [0001] The invention relates to an automatic intracranial cerebrospinal fluid drainage device, which is used for precise cerebrospinal fluid drainage for intensive care patients in neurosurgery, and belongs to the technical field of medical devices. Background technique [0002] For moderate to severe neurosurgery patients, intracranial hypertension is a common postoperative complication of neurosurgery patients, and it is the key factor leading to postoperative deterioration of neurosurgery patients. The important harm brought about by increased intracranial pressure is that it affects cerebral blood circulation, leading to a decrease in cerebral blood perfusion pressure (cerebral perfusion pressure = mean arterial pressure - intracranial pressure), resulting in reduced cerebral blood flow and insufficient oxygen supply to the brain. Inflict irreversible damage to the patient. Intracranial cerebrospinal fluid drainage is an important means to alleviate the ...

AI Technical Summary

Problems solved by technology

In view of the individual differences in patient conditions and the complexity of disease manifestations, it is not possible to precisely control the treatment of patients by simply relying on the detection of intracranial pressure to control drainage

Moreover, there are uncontrollable flow rate and flow rate in the drainage process, which may easily lead to serious problems such as respiration, which may affect the treatment effect and even lead to the deterioration of the patient's condition.

Moreover, the drainage process depends on the relative position of the patient and the drainage container, which is cumbersome to operate and relies on the experience of medical staff, which may easily lead to drainage failure
