Portable non-contact cornea diameter biological measuring instrument

Abstract

The invention relates to the technical field of medical instruments, in particular to a portable non-contact cornea diameter biological measuring instrument. The portable non-contact cornea diameter biological measuring instrument comprises a carrier, two laser transmitters and a movable adjusting mechanism, wherein the two laser transmitters are mounted on the carrier side by side, the transmitting directions of the two laser transmitters face the same direction, and the movable adjusting mechanism is connected with any one or two laser transmitters to adjust the distance between the two laser emitters so as to adjust the drop point distance of light beams emitted by the two laser emitters. The cornea diameter biological measuring instrument has the advantages that the structural design is simple and reasonable, the cornea diameter of a patient can be collected in a non-contact mode, the collecting process is safe, rapid and sanitary, eye infection of the patient cannot be caused, and cornea and conjunctiva tissue cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a portable non-contact corneal diameter biometer. Background technique [0002] At present, in the field of ophthalmology, the accurate measurement of corneal diameter is closely related to the diagnosis and treatment of many diseases, including cataract, corneal refractive surgery, ICL lens implantation and so on. The current measurement of corneal diameter mainly includes two categories: biological instrument measurement and manual measurement. Due to its dependence on instruments, biological instrument measurement is suitable for some patients suffering from other eye diseases, such as pterygium, corneal neovascularization, corneal scar, etc. There are obvious defects in the measurement, and there will be obvious errors in the measurement data. Therefore, for the measurement of corneal diameter, the means of manual measurement is still indispensable. At present, ...

Problems solved by technology

At present, the manual measurement of corneal diameter mainly uses methods such as corneal ruler and vernier caliper. In these measurement methods, since the measuring instrument needs to directly contact the patient's eye tissue (cornea, conjunctiva), it is necessary to adjust the diameter of the cornea during the measurement process. The patient is given surface anesthesia on the eye, and at the same time, the part of the instrument in contact with the eye tissue must be disinfected, which not only prolongs the operation time, but also causes damage to the corneal epithelium of the patient, and incomplete disinfection of the measuring instrument will also increase the patient's eye damage. The probability of infection, and the tip of the instrument will also cause varying degrees of damage to the cornea and conjunctiva tissue
