Portable rapid consistency test box and coil plate test method thereof

Abstract

The invention discloses a portable rapid consistency test box and a coil plate test method thereof. The portable rapid consistency test box comprises a test box body, a double-wing test ring and a test scale drawing plate, the upper part of the test box body is an upper cover capable of being opened and closed, a group of vertical track grooves are formed in opposite side surfaces in the test box body, and the test box body is provided with a horizontal adjusting device; the double-wing test ring comprises a hollow circular tube, a pair of symmetrical double wings extend from the outer side of the diameter of the hollow circular tube, the height of the double-wing test ring is lower than that of the test box body, and the length of the double-wing test ring is equal to that of the test box body; a gradienter is arranged on the test scale drawing plate, a plurality of concentric circles with the same intervals are drawn at the center position of the test scale drawing plate, and the test scale drawing plate is placed in the test box body and makes contact with the bottom of the test box body; the diameter of the hollow circular tube of the double-wing test ring is consistent with that of the smallest concentric circle on the test scale drawing plate; and the portable rapid consistency test box has the advantages of convenience in clinical consistency test, accuracy and reliability.

Description

technical field [0001] The invention relates to the field of consistency measurement of test samples, in particular to a portable rapid consistency test box and a coil plate test method thereof. Background technique [0002] Dysphagia is a common problem in the elderly and stroke patients. Patients with dysphagia are prone to choking when drinking the test samples, thereby increasing the risk of choking and aspiration pneumonia. Therefore, patients with dysphagia need to drink test samples of different consistency according to the degree of difficulty. [0003] Patients with dysphagia need to meet the consistency requirements when drinking the test sample. Texture description, viscosity, and LST are all important indicators for judging consistency in the "Chinese Expert Consensus on Dietary Nutrition Management for Dysphagia (2019 Edition)". [0004] When judging the consistency of the test sample, the texture description is very subjective and has a large error. Viscosi...

AI Technical Summary

Problems solved by technology

However, the detection plate does not have a positioning and directional movement device for the sample loading ring, resulting in the extended position of the sample on the determination plate, which is often displaced due to the experimental error of the operator, resulting in inaccurate readings

The test board has no horizontal adjustment device, which does not meet the requirements of the test board to be placed horizontally when testing by the LST method

In addition, additional operations such as timing are required during the detection process, which has high requirements for the detection environment and personnel, and increases the instability of the detection process.

And judging the consistency, it is only based on naked eye observation and cannot be read accurately, so it is only suitable for qualitative

[0008] In addition, there are testing instruments currently on the market for measuring the viscosity and fluidity of test samples, mainly rheometers, which are mostly used in laboratories to measure polymer melts, polymer solutions, suspensions, emulsions, coatings, inks and food rheological properties, the equipment is bulky, not portable, complicated to operate, and expensive, so it is not suitable for clinical application
