Urinary system stone measuring and analysing meter

Abstract

The analyzer comprises the laser generator, the first polaroid, the lens, the urine sample liquid pond, the second polaroid, the first and the second gratings, the data acquisition, the data processing unit and the data display terminal. As detecting urine sample is carried out outside human body, and technique of the laser light scattering and the nano analysis are utilized, the invention has the features of the simple and direct result analysis, fast, high accuracy, low cost. The analyzer has no any hurt to the human body and can examine a result before the grains of calculi with the certain size are generated.

Description

technical field [0001] The invention discloses a testing analyzer, in particular to a urinary system stone testing analyzer. Background technique [0002] Existing urolithiasis testing instruments include: abdominal plain film X-ray machine (KUB), intravenous urography (IVP) detector, ultrasound imager (B-ultrasound), magnetic resonance imaging urography (MRU) detection instrument, single photon emission computed tomography (SPECT) detector, antegrade pyelography detector and CT examination equipment, etc. The most commonly used instruments are the first three ["Guangzhou Medicine" 1994 (1): 28-29], but these instruments have the following disadvantages: the X-ray instrument in the plain film of the abdomen, because X-ray radiation will have a negative impact on the patient, It is not advisable to repeat the examination too much, and the high recurrence rate of urinary stones requires frequent testing; the gastrointestinal preparation before the examination also prevents th...

Problems solved by technology

The most commonly used instruments are the first three ["Guangzhou Medicine" 1994 (1): 28-29], but these instruments have the following disadvantages: the X-ray instrument in the plain film of the abdomen, because X-ray radiation will have a negative impact on the patient, It is not advisable to repeat the examination too much, and frequent examinations are required due to the high recurrence rate of urinary stones; the gastrointestinal preparation before the examination also prevents the examination results from being obtained quickly, and the diagnosis rate of non-calcium stones is not high

When the ultrasonic imaging detector is used, the upper pole of the kidney is covered by the lungs, and the outer and rear sides are covered by the ribs, so part of it cannot be displayed. At the same time, this method will also cause misdiagnosis, and the thorns are regarded as stones, and the analysis rate of the instrument is low. The professional proficiency level of the patient will affect the stone test results, etc.

[0003] In addition, using the above instruments to detect stones, it is impossible to know in advance whether a person suffers from stones, and it can only be detected after the stones have grown to a certain size and shape; Both cause the existing cost of diagnosis of urinary calculi to be high, and it is not easy to popularize and promote in primary hospitals
