Description

Vision monitoring device

Technical field

This utility model relates to ophthalmic medical apparatus and instruments, relates in particular to a kind of device for monitoring carrying out the vision of the patient's art eye after Orbital Surgery.

Background technology

After carrying out Orbital Surgery, the reason of patient's visual deterioration or forfeiture mainly contains following two kinds:

1, in operation process: patient's optic nerve sustains damage, optic nerve blood supply is damaged, and socket of the eye is pressed acutely to increase to wait and all can be caused the even forfeiture of going down of patient's art eye vision;

2, after operation: the supply vessels of patient's socket of the eye inner tissue's edema or hemorrhage compressing optic nerve and optic nerve, causes optic nerve blood supply insufficiency, and then cause patient's art eye vision to go down even losing.

In addition, in 24-28 hour after surgery, patient's art eye socket inner tissue edema is serious.For avoiding Orbital Surgery patient Shu Yanyin socket of the eye inner tissue's edema or hemorrhage DE, medical personnel need carry out Postoperative visual acuity monitoring to patient's art eye after operation.But, for alleviating patient's art eye socket inner tissue edema, avoid patient's art eye to be subject to accidental injury, within after surgery initial several days, must carry out pressure dressing to patient's art eye.The method of traditional monitoring patient art eye vision is: medical personnel regularly open patient's bandage for dressing, allows patient directly feel to have or not light or with torch, patient's art eye to be checked and examined, and allows patient feel to have or not light.Open patient's bandage for dressing, easily cause patient's art eye socket inner tissue edema to increase the weight of, and with torch, patient's art eye is checked and examined, the light that patient feels is likely that the eye of patient health is experienced, and monitors inaccurate.

Utility model content

For avoiding patient's art eye socket inner tissue edema to increase the weight of, improve monitoring accuracy, the utility model proposes a kind of vision monitoring device, this vision monitoring device comprises DC source, miniature light-emitting component, wire and gauge tap, described DC source is connected by described wire with described miniature light-emitting component, and described gauge tap is between described DC source and described miniature light-emitting component and control the light on and off of described miniature light-emitting component.

When using this vision monitoring device to monitor the vision of patient's art eye, miniature light-emitting component is placed in to the bandage for dressing layer of patient's art eye, and has one deck bandage for dressing at least between this miniature light-emitting component and patient's art eye.Like this, Closed control switch, miniature light-emitting component is luminous, can draw monitoring result according to patient's the result of experiencing, easy to use; The light that this miniature light-emitting component sends can not experienced by patient's healthy eye, has improved the accuracy of monitoring.In addition, miniature light-emitting component sends soft light at patient's art eye place, can either make patient's art eye experience light, can not stimulate again patient's art eye.

Preferably, described DC source is positioned at control box, and described gauge tap is positioned on the box wall of described control box, is convenient to the break-make of control circuit, easy to use.
