Description
Technical Field
The utility model relates to a simple and easy device for observing the pupil especially relates to a pupil observation measuring device.
Background
The pupil is a small circular hole at the center of the iris of the eye, and the diameter of the light entering the eye is about 3-4 mm and is a perfect circle. Its enlargement and contraction is governed by two smooth muscles that make up the iris, the sphincter pupillae and the dilated pupillary muscle. Miosis is dominated by parasympathetic fibers of the oculomotor nerves, and pupillary dilation is dominated by sympathetic nerves. The pupil size adjustment is to adjust the amount of light entering the eye, the pupil shrinking when the external light is bright and the pupil expanding when the light is dim. The size of the pupil varies with the intensity of light, but also depends on age, refraction, physiological conditions, etc.
In medicine, doctors often assist in determining the physical condition of patients by observing the pupils, and therefore, the method is one of the important diagnostic means for some diseases. For example, peripheral oculomotor nerve injury can cause mydriasis on the affected side, slow or disappearance of direct and indirect light reflection, dyskinesia of the eyeball, absence of mental changes and hemiplegia of the opposite limb, such as ocular nerve injury caused by skull base fracture; cerebral ischemia and anoxia lead to large oxygen consumption of brain, poor anoxia tolerance, coma, bilateral mydriasis and fixation, disappearance of light reflection, which are commonly seen in circulation, respiratory arrest, status epilepticus, severe intracranial pressure increase and the like.
In order to more accurately observe the size of the pupil of a patient, a doctor often realizes the measurement of the size of the pupil through tool cooperation, and a flashlight and a ruler are adopted for clinically observing the pupil of the patient at present to observe the reflection and the size of the pupil. Because the flashlight needs to be held by one hand, the eyelid of the patient needs to be opened by the other hand, and the measuring tool needs to be held, the operation is very inconvenient, and the reading may have errors, which affects the judgment of the state of an illness.
SUMMERY OF THE UTILITY MODEL
The objective of the present invention is to provide a pupil observation and measurement device convenient for operation to solve the above problems.
The utility model discloses a following technical scheme realizes above-mentioned purpose:
the utility model provides a pupil observation measuring device, includes the barrel, be equipped with the button on the barrel, be equipped with the battery in the barrel, the first end of barrel is equipped with the light source, the button is used for control the opening of light source, close, pupil observation measuring device still includes the cover of tube-shape, the internal diameter of cover is greater than the external diameter of barrel, the first end of cover with the connection can be dismantled to the first end of barrel, the position that is close to the second end in the cover is equipped with radial transparent plate, be equipped with on the transparent plate and be sharp range and opaque scale mark.
In the structure, the structure of the cylinder, the key and the battery is the structure of a conventional flashlight, in order to make the light generated by the light source cylindrical as much as possible, a convex lens can be arranged in front of the light source, or a surface light source can be directly adopted without the convex lens, and the light beam is cylindrical basically when the distance is short; the cylinder cover is detachably connected with the cylinder body, so that a user can conveniently take down the cylinder cover when the pupil size is not required to be accurately acquired, the device is a common flashlight, and the cylinder cover is mounted when the pupil size is required to be accurately acquired, so that the device has the function of acquiring the pupil size through the scale marks irradiated on the pupil while illuminating, and is very convenient to use; the transparent plate can be a thin glass plate or a plastic plate with good light transmission, and the second end of the cylinder cover can protect the transparent plate.
According to actual needs, the barrel cover is in threaded connection or buckled connection with the barrel body.
Preferably, the light source is a surface light source formed by arranging a plurality of LED patches, the light source is electricity-saving and high in brightness, emitted light beams are basically cylindrical when the distance is close, pupil size can be accurately acquired, normal use is not affected even if a few LED patches are damaged, and service life is prolonged.
Preferably, in order to control the switch and hang the device on a pocket of a user, the key is arranged on the end face of the second end of the barrel, and a hook for hanging the barrel is arranged on the outer wall of the second end of the barrel.
The beneficial effects of the utility model reside in that:
the utility model discloses a can dismantle the connection cover on the barrel to set up the transparent plate and set up the scale mark on the transparent plate in the cover, make this pupil observe measuring device have torch function and pupil size measurement function concurrently, two kinds of functions can also be according to demand quick separation and integration, and the measurement mode only needs to hand the barrel and directly shines the pupil and obtains the pupil size through the scale mark that shines on the pupil, and the size measurement is accurate and the operation is very convenient, simple structure is practical; the transparent plate is arranged in the cylinder cover and protected by the second end of the cylinder cover, so that the strength requirement of the transparent plate can be reduced and the transparent plate can be designed to be as thin as possible, thereby improving the light transmittance and further improving the observation definition and the measurement accuracy.
