Embodiment Construction

[0021] Such as figure 1 The flowchart for establishing the database for the laser speckle blood perfusion imaging system is shown, which specifically includes the following steps:

[0022] 1. Basic information collection: For healthy people, the name, gender, age, and medical history of the tested object are collected. For shock patients, the hospital number, name, gender, age, drug use and measurement date of the measured object were collected.

[0023] 2. Contrast image collection: Use a laser speckle blood flow imaging device (consisting of a laser, a beam expander, a CCD camera, and a PC terminal) to take pictures of the backs of the left and right hands of the subject under test. The specific steps for obtaining the contrast image are as follows:

[0024] 2.1. Adjust the distance between the shooting device and the back of the hand under test so that the camera can capture the entire back of the hand;

[0025] 2.2. Set the exposure time of the camera to 100ms and the me...

Abstract

The invention relates to an establishment method of a database for a laser speckle blood perfusion imaging system. A laser speckle blood perfusion imaging device is used to quantify the microcirculation condition of a measured object and establish a database. A database is established for measurement data, and the establishment method of the database comprises the following steps: collecting basicinformation; acquiring a contrast image; performing data analysis on the contrast image; establishing a normal microcirculation database and a shock microcirculation database; and establishing shockassessment database. The database is reasonable in classification, large in information amount and convenient to call, standardized storage of data is achieved, and shock evaluation can be achieved through database calling.

Description

technical field [0001] The invention relates to a database establishment technology, in particular to a database establishment method for a laser speckle blood perfusion imaging system. Background technique [0002] Shock is a systemic pathological process characterized by tissue and organ microcirculation disturbances. Microcirculation disturbances play an important role in the physiology and pathology of shock and are closely related to the prognosis of patients. With the in-depth research on the pathophysiology of shock, it is found that microcirculation disturbance seems to occur earlier than shock. Therefore, understanding the changes in microcirculation and vascular reactivity in shock is of great significance for guiding treatment and evaluating prognosis of shock. Laser speckle blood flow imaging technology is a non-contact, non-invasive, high temporal and spatial resolution, large-area blood flow velocity detection technology, which can quantify the microcirculatio...
