Nystagmus Spectacle with Bajonet interlocking and battery grip by Prof. Frenzel
Modern vestibular diagnostics require a high degree of precision when looking for spontaneous or provoked nystagmus. In many cases, the only way of making a correct diagnosis was to perform a technically complex electronystagmography (ENG). The new Nystagmus spectacles by Prof. Frenzel is especially suitable for short-term examinations. Thanks to the new bajonet connection and the different connection wires, the Nystagmus Spectacle can be quickly transformed into spectacle that are suitable for various examination e.g. for storing or examinations on swivel-chairs. By using the corresponding components the Nystagmus Spectacle come up to the individual expectations of the doctor. The actual examination using these goggles takes place in a dark or a heavily dimmed room. The illumination of the inside of the goggles causes the patient to lose visual contact with his/her surroundings (preventing nystagmus-inhibiting visual fixation). At the same time, it is especially easy to observe the patient’s brightly illuminated eyes using magnifying lenses. This means it is often possible to detect immediately, just by looking at the patient, pathological nystagmus processes that would be impossible or difficult to detect, even when looking sideways.
Connection wire DEHAG Type 7.03.06
In order to provide the Nystagmus Spectacle with power, you can use the connection wire Type 7.03.06 to connect it with the bajonet connection. After that it can be connected with the DEHAG-Regulating transformer or with the DEHAG-Battery container instead of using the battery hold.
Bajonet wire Type 7.03.05
The bajonet wire Type 7.03.05 connects the Nystagmus Spectacle with the battery hold and thus allows a mobile and flexible working independent of the power supply. In this combination it is especially ideal for examinations on swivel-chairs.
Clip-headband Type 5.01.08
The clip headband lets you fit the nystagmus goggles securely in front of the patient’s eyes. This in turn makes it easy to look for provoked nystagmus, e.g. by shaking the patient’s head or by performing swivel-chair or postural examinations. Slightly squeeze the clip headband to remove it from the slots of the nystagmus spectacles.
Replacement Cover Type 57.00.02
The cover ensures the shielding of the light bulb and guarantee an indirect illumination of the Nystagmus Spectacle. The Nystagmus Spectacle Type 703 can be operated with a 4 Volt; 0.23 Ampere; 1 Watt replacement lamp.
