Intelligent flashlight convenient for pupil zooming-out and zooming-in examination of patient

Abstract

The invention discloses an intelligent flashlight convenient for pupil zooming-in and zooming-out examination pf patient, which is characterized by comprising a bearing frame, a handheld handle and an examination flashlight; the inspection flashlight is detachably connected to the bearing frame in a sleeving mode, the handheld handle is detachably connected to the side edge of the bearing frame, an image sensor is fixedly arranged on the inner side of the head end of the inspection flashlight, and an aperture is fixedly arranged on the outer ring of the image sensor; the device is designed in a flashlight mode, pupil images of a patient are collected through the high-definition image sensor and analyzed and calculated through the processor, and finally the size value of the pupil of the patient is obtained and displayed on the display screen. Medical workers do not need to stare at pupils of the patient for observation, the pupil size value can be obtained by directly collecting and analyzing the pupil image of the patient through the device, and then the pupil size value is compared with the pupil size of a normal person to make a diagnosis conclusion, so that on one hand, the workload of medical workers is relieved, on the other hand, the pupil examination accuracy is improved, and the medical workers can conveniently judge the examination result and give an advice.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an intelligent flashlight which is convenient for patients' pupil constriction and enlargement inspection. Background technique [0002] The pupil is the small round hole in the center of the iris in the animal or human eye, which is the channel for light to enter the eye. Contraction of the pupillary sphincter muscle on the iris causes the pupil to narrow, contraction of the pupillary dilator muscle causes the pupil to dilate, and the dilation and constriction of the pupil control the amount of light entering the pupil. [0003] The smooth muscle arranged circularly along the pupil is called the pupillary sphincter, and the pupil narrows when the sphincter contracts; the smooth muscle arranged radially along the pupil is called the pupil dilator, and the pupil dilates when the enlarged muscle contracts; because the pupil can dilate or shrink, it can act To r...

Problems solved by technology

[0006] Nowadays, in the clinical examination of abnormal pupillary constriction and dilation, most of the medical staff directly observe with the naked eye, relying on experience to judge whether it is abnormal dilation. During this period, there are too many uncertain factors,
