Novel ophthalmic examination pen

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a novel ophthalmic examination pen.

Background

Medical devices refer to instruments, devices, appliances, materials or other items used in the human body, either alone or in combination, and also include the software required. The medical equipment is the most basic element of medical treatment, scientific research, teaching, institutions and clinical discipline, wherein the ophthalmic examination comprises eyelid, conjunctiva, lacrimal apparatus, eyeball position, eye socket and anterior segment examination, the ophthalmic examination is an important component in physical examination, and in the ophthalmic examination process, the ophthalmic examination pen is an examination instrument which is convenient for an ophthalmologist to carry out examination assistance on eyes of a patient so that the ophthalmologist can make more accurate judgment.

In the ophthalmic test, some information needs to be recorded, but in the actual test, the recording pen is not carried in real time, so that a certain trouble may be caused.

However, the existing inspection pen has a single function, usually only has a lighting function, and cannot solve the above problems.

Meanwhile, the existing inspection pen has extremely smooth surface, is slightly not noticed and easy to slide, and can cause damage to eyes of patients in eye inspection, so that the existing inspection pen is dangerous.

In view of the above problems, it is necessary to provide a new inspection pen having a plurality of functions, capable of realizing illumination and recording functions, and also reliable in holding, not easy to slip, and very necessary to improve the safety in inspection.

Disclosure of Invention

In view of the above, the utility model aims to solve the problem of sliding off during use in the prior art, and provides a novel ophthalmic examination pen.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the utility model provides a novel ophthalmic inspection pen, includes the pen body, pen body one end is fixed to be provided with the threaded rod, the inside fixed gel ink pen that is provided with of threaded rod, threaded rod threaded connection has the thread bush, the inside middle fixed rubber sleeve that is provided with of thread bush, the pen body is kept away from the fixed illumination joint that is provided with of one end of threaded rod, the fixed a plurality of inspection lamps that are provided with of illumination joint preceding terminal surface, the illumination joint outer wall is provided with the protective housing, a protective housing lateral wall is fixed to be provided with annular lug, annular draw-in groove has been seted up to pen body one side wall, pen body inside one side is fixed to be provided with two telescopic links, two telescopic link upper end fixedly connected with handle, handle both sides wall is all fixed and is provided with the lug.

Further, a charging port is fixedly arranged on one side of the outer wall of the pen body.

Further, a battery groove is formed in one side, far away from the charging port, of the outer wall of the pen body.

Further, the radius of the rubber sleeve is larger than that of the gel pen.

Further, the annular protruding block is matched with the annular clamping groove.

Further, the number of the plurality of inspection lamps is three.

Further, the anti-wear layer is fixedly laid at the lower end of the handle.

Further, the wear layer is comprised of a rubber material.

The utility model has the following beneficial effects:

1. the novel ophthalmic inspection pen has the function of dual purposes of inspection and recording, the traditional ophthalmic inspection pen needs to record at any time through the pen when in use, so that inspection conditions are conveniently known, but the recording pen cannot be carried in real time during actual inspection, and the inspection missing is caused.

2. The novel ophthalmic inspection pen provided by the utility model has the function of protecting the illumination area, and after the inspection pen is used, the inspection pen is usually directly placed at the storage position and cannot be protected, so that dust appears on the surface of an illuminating lamp to influence the inspection effect of later use, and after the inspection pen is used, the annular protruding block is only clamped in the annular clamping groove to form a closed space, so that the dustproof effect is achieved.

3. The novel ophthalmic examination pen has the function of assisting in holding the pen, when the examination pen is used, generally, when an operator performs eye examination, if the operator slides or is frightened during operation, the examination pen can fall off and easily fall on the face of a patient, even the eyes are injured, the danger is high, when the novel ophthalmic examination pen is used, the user only needs to pull the handle outwards to insert fingers into the eye, and when the novel ophthalmic examination pen is not used, the user only needs to push the handle until the lug is clamped in the clamping seam on the outer wall of the examination pen, so that the effects of ensuring stable holding and not occupying too much space are achieved.
