Packaging device for artificial cerebrospinal fluid

Abstract

The invention relates to a packaging device for artificial cerebrospinal fluid. An infusion bag is internally and sequentially provided with a foaming chamber, a liquid chamber B and a liquid chamberA from top to bottom; the liquid chamber B stores an alkaline electrolyte solution containing sodium bicarbonate, and the liquid chamber A is acid and contains glucose; partition belts which can be opened at a time are arranged between the foaming stick chamber and the liquid chamber B and between the liquid chamber B and the liquid chamber A respectively, and the partition belts make the foamingstick chamber, the liquid chamber B and the liquid chamber A isolated. A foaming stick is fixed on the inner wall of an infusion bag by gluing through a shaft rod, one end of the shaft rod is horizontally embedded into a vent pipe, and the other end of the shaft rod is solid. The other end of the vent pipe penetrates through the infusion bag, extends outward to form an exposed pipeline and is sequentially provided with a one-way check valve, a closed pipe clamp and a pipe-end nut, mixed gas is introduced through the vent pipe, and the bottom of the infusion bag is provided with a sealed air outlet / dosing hole and an infusion hole.

Description

technical field [0001] The invention belongs to the technical field of medical solution storage and use devices, in particular to an artificial cerebrospinal fluid packaging device. Background technique [0002] With the development of neuroscience technology, artificial cerebrospinal fluid is used more and more frequently in neuroclinical and neuroscience research experiments. Although there are various artificial cerebrospinal fluid formulas, some components in artificial cerebrospinal fluid (such as calcium, glucose , sodium bicarbonate, etc.) are prone to precipitation and hydrolysis between each other, and cannot be stored for a long time. Moreover, during the use of artificial cerebrospinal fluid, there are high requirements on pH, electrolyte concentration, blood gas status and aseptic conditions. These factors limit the use of artificial cerebrospinal fluid. used in clinical and scientific research. [0003] At present, most of the artificial cerebrospinal fluid use...

AI Technical Summary

Problems solved by technology

Although the problem of stable preservation of artificial cerebrospinal fluid has been solved, the blood gas state of the mixed artificial cerebrospinal fluid may have a serious impact on the human nervous system, so it is necessary to fully foam the mixed gas to increase CO 2 Content, adjust the pH, in order to keep the mixture stable for a period of time

[0004] At present, there is no unified formula, packaging and use specification for artificial cerebrospinal fluid used in clinical or scientific research
