Pressure monitoring and adjusting device for external drainage system

Abstract

The invention discloses a pressure monitoring and adjusting device for an external drainage system. The pressure monitoring and adjusting device has the advantages that intracranial pressure data of apatient are detected by a detection device and transmitted to a controller, the controller transmits the intracranial pressure data to a display screen for display, so that a doctor can acquire the current intracranial pressure of a patient in real time, and determination of a therapeutic schedule of medical staff and therapy are accelerated. Besides, the acquired intracranial pressure of the patient is compared with intracranial pressure and intracranial pressure adjusting bottle relative adjustment height data in a database by the controller, an intracranial pressure adjusting bottle is adjusted to a corresponding height, a lifting device is driven by a lead screw, the lifting process is stable, and intracranial infection of the patient caused by lifting instability of the intracranialpressure adjusting bottle is avoided. When the intracranial pressure adjusting bottle rises to be abutted to a lead screw fixing plate, the abutting detection device generates abutting signals and transmits the abutting signals to the controller, the controller outputs alarm signals and the intracranial pressure data to an external hospital duty room, and an operator on duty timely finds and handles the abnormal condition of the patient.

Description

technical field [0001] The invention relates to the field of surgery, and more specifically relates to a pressure monitoring and adjusting device for an external drainage system. Background technique [0002] Extracranial and lumbar puncture tube placement for continuous external drainage is a common treatment measure in clinical neurosurgery. Draining cerebrospinal fluid can relieve the increase in intracranial pressure and accelerate the discharge of inflammatory or bloody cerebrospinal fluid. [0003] The extracorporeal drainage system includes a drainage catheter, a cranial pressure regulating bottle, and an effusion bag; we know that adjusting the position of the cranial pressure regulating bottle can control the drainage speed. At present, when major hospitals perform drainage operations, most of them fix the intracranial pressure regulating bottle on the appropriate position of the bed frame or infusion stand, and adjust the height of the intracranial pressure regulat...

AI Technical Summary

Problems solved by technology

At present, when major hospitals perform drainage operations, most of them fix the intracranial pressure regulating bottle on the appropriate position of the bed frame or infusion stand, and adjust the height of the intracranial pressure regulating bottle at any time according to the drainage process and the development of the disease to control the drainage speed. When adjusting, the intracranial pressure adjustment bottle is not easy to fix or the height span is large, which is troublesome to operate and affects the drainage effect; the adjusted height is determined entirely by the experience of medical staff, and the error is large, which not only affects the treatment effect, but also easily causes other diseases

Even if some hospitals have a scale plate on the bed frame or infusion stand, the intracranial pressure regulating bottle is fixed on the scale plate, and the patient’s current intracranial pressure is read according to the height position of the scale plate, and the intracranial pressure regulating bottle is adjusted according to the scale on the scale plate However, there are still the following deficiencies: 1. The height of the scale plate is not easy to adjust. There is no reference when adjusting, and it needs to be adjusted repeatedly, which is troublesome to operate. 2. There is no reference for the horizontal and vertical positions of the scale plate, and it may tilt. The pressure data is inaccurate, and the reading error is large; 3. The scale line corresponding to the corresponding part of the patient's body on the scale plate is not easy to determine, and the reading error is large

The above-mentioned errors will cause a large difference between the measured intracranial pressure and the actual intracranial pressure. If the intracranial pressure cannot be accurately and reliably known at any time, there will be no objective data on the change of intracranial pressure for reference, and doctors cannot be faster and better. Taking treatment measures may delay the best time for treatment
