Pressure monitoring and regulating device for in-vitro drainage system

Abstract

The invention discloses a pressure monitoring and regulating device for an in-vitro drainage system and relates to a neurosurgery medical instrument. The pressure monitoring and regulating device is provided with a monitoring plate, wherein the monitoring plate is provided with a permanent seat and is vertically provided with a sliding chute; one side of the sliding chute is horizontally provided with water column scale lines and water column scale marks; the monitoring plate on the other side of the sliding chute is horizontally provided with mercury column scale lines and mercury column scale marks; the '0' water column scale line and the '0' mercury column scale line are arranged on the same horizontal plane; a regulating slip sheet is arranged in the sliding chute and is provided with a locking knob; the lower part of the regulating slip sheet is provided with a connecting seat; the connecting seat is vertically provided with an intracranial pressure regulation bottle; the outer wall of the intracranial pressure regulation bottle is provided with a liquid inlet position marker line; the upper end of the monitoring plate is provided with a level gauge; the parts, corresponding to a water column reference scale line and a mercury column reference scale line, of the monitoring plate are provided with locating laser pens; and one side of the monitoring plate is provided with an intracranial pressure monitor mounting plate. The height of the intracranial pressure regulation bottle is convenient to regulate, and the intracranial pressure data obtained by observation is precise and reliable.

Description

technical field [0001] The invention relates to a neurosurgery medical instrument, in detail it is a pressure monitoring and regulating device for an external drainage system. Background technique [0002] According to statistics, about 800,000 to 1,000,000 patients with cerebral hemorrhage (the first onset) occur in my country every year, and it is estimated that there are more than 1,000,000 recurrent cases every year. In addition, in recent years, with the development of transportation, construction and other industries, the incidence of traumatic cerebral hemorrhage has risen sharply. Currently, there are more than 500,000 new cases of traumatic cerebral hemorrhage patients every year. Moreover, the mass effect of cerebral hemorrhage (hematoma) causes high intracranial pressure and brain herniation, leading to and aggravating secondary cerebral edema and brain damage, causing various complications and threatening life.

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
