探测器概况JJT—3型眼科金属异物探测定位仪(简称探测器)是根据电磁感应原理来感知金属异物而制成的,主要用于眼科金属异物手术摘除时的定位;由我院与温州仪器仪表厂共同研制,经多次改进制成本探测器。特点:1.探头细小有直、弯两型;分磁性,非磁性两种探头;2.为使定位精确,使灵敏度保持1∶5之间,这样能使阳性反应区缩小至一点;3.为保证平衡防止出现假阳性,特制了热平衡板极以抵消体温的影响;4.备有插销,可联接示波器观察波形变化,有助于异物定位及是否磁性的判定。
Detector Overview JJT-3-type ophthalmic metal foreign body detection locator (referred to as the detector) is based on the principle of electromagnetic induction to detect metal foreign body and made, mainly for ophthalmic metal foreign body surgical removal of the positioning; by our hospital and Wenzhou apparatus Instrument Factory jointly developed by the cost of improving the system detector many times. Features: 1. The probe has a small straight, curved two; sub-magnetic, non-magnetic two probes; 2. In order to make the positioning accurate, the sensitivity to maintain between 1: 5, so that the positive reaction area reduced to one point; In order to ensure the balance to prevent false positives, a special heat balance plate to counteract the effects of body temperature; 4. With a latch, you can connect the oscilloscope to observe the waveform changes, help foreign body positioning and whether the magnetic determination.
