Problems solved by technology

[0003] Traditionally, observers have been making rough estimates by visual inspection. This method has large errors, low accuracy, and is greatly affected by the observer's personal experience.
[0004] The pupil tester in the prior art generally uses an industrial computer platform, which is relatively complicated in information collection, storage, analysis and output procedures, and has a large volume and power consumption, high cost, and is inconvenient to carry, especially cannot be used in critically ill patients. widely used

Abstract

The invention discloses a portable pupil response sensitivity testing device which comprises a high-brightness light-emitting diode (LED) lamp, a charge coupled device (CCD) camera, a microprocessor, a casing, a digital tube, a battery and a switch. The device adopts the CCD camera which is aligned to the eye of a patient, the microprocessor collects a frame of image data through a decoding chip, and the pupil diameter can be obtained through calculation. The microprocessor controls turning on of the high-brightness LED lamp through input and output pins to stimulate the pupil of the patient and collect the other frame of image of the pupil, the diameter of the pupil stimulated by intense light is obtained through the same calculation. The larger the specific value of the two diameters is, the more sensitively the patient responses, the more obvious the life sign is. The specific value of the two diameters is subjected to four-grade division and displayed on the digital tube, so that a doctor can visually judge the illness degree and change of the patient. The device can achieve automatic patient pupil response sensitivity testing, and is safe and convenient to use, high in accuracy and capable of effectively overcoming the shortcomings of visual inspection conducted by the doctor by experience at present.

Description

technical field [0001] The invention relates to the field of medical testing instruments, in particular to a portable pupil response sensitivity testing device. Background technique [0002] For neurological patients and critically ill patients, doctors generally use medical flashlights to illuminate the patient's eyes and determine the sensitivity of the patient's response to strong light, so as to qualitatively judge whether the patient's vital signs are obvious. Changes in pupil size and response sensitivity to light directly indicate the development of the disease. [0003] Traditionally, observers have been making rough estimates by visual inspection. This method has large errors, low accuracy, and is greatly affected by the observer's personal experience. [0004] The pupil tester in the prior art generally uses an industrial computer platform, which is relatively complicated in information collection, storage, analysis and output procedures, and has a large volume an...
