Description
Technical field
The present invention relates to medical detection technology, and in particular to a kind of noninvasive eye socket pressure measuring device and measuring method.
Background technology
Blow-out fracture often causes endophthalmos, ocular motility disorder and diplopia, need to carry out orbital reconstruction reconstruction operations,
Diplopia is corrected, improves profile.Orbital Surgery can cause the damage of socket of the eye inner tissue and eye socket gap syndrome, cause in art and postoperative regard
Power is lost, and the volume of the bone eye socket of its reason is fixed, and operation causes soft tissue reactive edema, bleeding, implant intraobital in socket of the eye
Osteocomma or artificial material, which repair socket of the eye wall, resets eyeball etc. causes eye socket pressure rise, occur when serious socket of the eye perfused tissue reduce,
Eye socket is in high state, in ciliary posterior artery, arter centralis retinae ischemic and obstruction, socket of the eye muscle and optic nerve etc. organize into
Row hypoxic-ischemic, so as to endanger visual function, or even cause visual loss.In Orbital Surgery if can direct measurement to eye
Organizational stress in socket of the eye, the compression situation of the tissues such as blood vessel in socket of the eye, nerve just can be objectively assessed, judges implant intraobital quantity of material
It is whether excessive, therefore directly the detection of socket of the eye pressure has larger clinical value in Orbital Surgery.Blow-out fracture prosthesis is most tight
The complication of weight is blindness, and incidence is 0.3~8.3%, and reason mainly has two：When operation technique directly contribute regard god
Through damage, second, socket of the eye pressure rise caused by hemotoncus or socket of the eye tissue edema after ball.The former can be avoided by careful operation in art, after
Person need to be by operation and postoperative monitoring, early detection simultaneously take measures in time.With blow-out fracture and other ophthalmology
Disease is increasing, it is necessary to which the demand for carrying out accurate, quick, safe measurement eye socket pressure is increasing, and substantial amounts of patient surveys

Traditional eye socket pressure score presses measuring instrument and non-invasive direct contact type eye orbitonometer for invasive directly socket of the eye.Fig. 1 is invasive
Direct socket of the eye pressure measuring instrument schematic diagram, the direct socket of the eye pressure measuring instrument of wound formula need detector to puncture eyeball, it is necessary to anaesthetize in measurement process
Agent mitigates measured's pain, and its main composition is：Pressure detector, pressure transmitter, pressure monitor.The device uses 18G
Vein lien cannula needle is as pressure detector.Venous detaining needle is connected to pressure transmitter by a pressure detecting pipe, passes
Lead device to reconnect in invasive pressure monitoring instrument, so that socket of the eye pressure measurement result is recorded by figure and data two ways.Should
A syringe is designed with device.Venous detaining needle, pressure transmitter, pressure-measuring pipe, syringe and three-way connection be it is sterile and
It is disposable, and be assembled under sterile conditions, invasive directly socket of the eye pressure measuring method easily causes infection, measurement cost
It is high.Non-invasive direct contact type eye orbitonometer is non intelligent product, and margo orbitalis is basic point on the outside of eyes, is pacified on hold-down support
Parallel front and back support is filled, manometer seat and movable bearing support, the projection in front of pressure-measuring head and two bearings are put down on set on support
During row, pressure-measuring head is placed on eyelid, pushing away orbitonometer forward makes the jut of two bearings be pressed in margo orbitalis, and socket of the eye pressure passes through eye
Ball eyelid passes to pressure gage.Measured value is read by pressure gage (or dial), then by conversion table, conversed real
Eye socket pressure.
