2, because described opening on eyelid hook fixedly mounts and be useful on the baffle plate that blocks eyelashes, be not subject to the impact of eyelashes in operation process, can prevent deplumation, what impact was performed the operation carries out smoothly.
3, because described absorption plant comprises the drainage tube being fixedly installed on described support arm, described drainage tube one end is towards the described eyelid hook of opening, the other end is communicated with drainage bottle, between described drainage tube and drainage bottle, be provided with drain sacculus, thereby under the effect of drain sacculus, operation residual liquid enters drainage bottle by drainage tube, clean hygiene, convenient and swift, greatly alleviated medical personnel's the amount of labour.
4, because handle is provided with anti-slip veins, can increase the frictional force between hands and handle, prevent the phenomenon of skidding in turning handle.
But, in this technical scheme, also existing and drive eyelid hook and patient's eye contact area is excessive, in use procedure, patient's sense of discomfort is stronger, easily occurs the problem of eyelid hyperemia.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of ophthalmology eye speculum, can solve the deficiencies in the prior art, has improved the contact structures of eye speculum and eye, has solved the problem of eyelid hyperemia in use procedure.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of ophthalmology eye speculum, comprise two hinged support arms and a drain arm, in the middle of two support arms, be provided with telescopic advance lever, the end thread of support arm is connected with arc-shaped draw hook, on described arc-shaped draw hook, be provided with several hemispherical projections, in hemispherical projections, be provided with dosing holes, support arm and arc-shaped draw hook inside are provided with delivery tube, dosing holes is connected with delivery tube, the surface of hemispherical projections is provided with two grooves, groove is symmetrical arranged with respect to dosing holes, in groove, by the first spring, be connected with rubber slide block, the degree of depth of the aspect ratio groove of rubber slide block exceeds 0.1～0.2mm, rubber slider top is provided with medical gauze layer.
As preferably, on described support arm, be provided with elastic metallic yarn, the top of elastic metallic yarn is provided with colored spheroid.
As preferably, on described support arm, be also provided with sleeve.
The beneficial effect that adopts technique scheme to bring is: by hemispherical projections is set on arc-shaped draw hook, can optimize the way of contact of arc-shaped draw hook and eyelid, the eyelid of avoiding large area extruding eyelid to cause is congested.The rubber slide block arranging in hemispherical projections can alleviate hemispherical projections and contact with the direct rigidity of eyelid when hemispherical projections contacts with eyelid position, makes eyelid can not should be direct extruding and produces congested problem.The degree of depth of the aspect ratio groove of rubber slide block exceeds 0.1～0.2mm, can optimize the contact pressure at rubber slide block and eyelid position.Medical gauze layer can absorb eye portion secretion in time, avoids rubber slide block and eyelid generation relative sliding to cause clamping unstable.At needs patient eyeball, fixedly coordinate treatment time, colored spheroid is put to tram, patient watches colored spheroid attentively.Sleeve on support arm can be placed other treatment apparatus temporarily, has reduced medical worker and has come and gone the time that picks and places apparatus.
