Embodiment Construction

[0019] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0020] Such as figure 1 As shown, an eye electrode with shape memory function provided by the present invention includes a contact part 1 and a transmission part 2. The contact part is a closed ring made of a shape memory material, and the phase transition temperature of the shape memory material is the same as that of the human body. Adapt to the temperature, so that the closed ring is placed on the patient's cornea, which can produce a shape memory effect under the action of human body temperature, changing from an irregular shape to a regular circle, so that the ocular potential signal can be received in a 360-degree orientation of the cornea ,Such as figure 2 As...

Abstract

The invention discloses an eye electrode with a shape memory function and belongs to the technical field of medical instruments. The eye electrode comprises a contact part and a transmission part, wherein the contact part is a closed ring made of a shape memory material, the closed ring is placed on the cornea of a patient to become a regular round to receive eye potential signals, the transmission part is a lead connected with the contact part, and the lead transmits the eye potential signals out. The eye electrode can keep regular shape and is not prone to deformation or winding, and the problem that the test accuracy is affected by winding is solved. The eye electrode has a round memory shape and can receive signals at 360 degrees, so that signals are comprehensively received without missing, and the detection accuracy can be further improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an eye electrode with a shape memory function. Background technique [0002] The visual function test electrodes include at least eye electrodes. Existing eye electrodes usually use thin-wire electrodes, which are usually made of metal fibers the size of a hair, which is less irritating to the eyes, can be placed on the cornea, and can be made into a circle, and the signal is stable, but due to The diameter is small, the spatial position is uncertain, and there are problems of winding and insufficient signal stability. [0003] In view of the above problems, it is necessary to improve the thin wire electrode so that it will not be entangled, and a stable potential signal can be obtained, which is of great help to improve the accuracy of detection. Contents of the invention [0004] In view of this, the present invention provides an eye electrode for the ab...
