Rebound Tonometer
NO CALIBRATION NO ANESTHESIA FA-800
Advantages:
1.The measurement results are accurate and consistentand proven correct through clinical studies.
2.Itis painless and therefore creates no anxiety No local anaesthetic is needed
3.Repeated measurements could be conducted without nearly any harm to the eyes of adults
and children.
4. Easy manipulation for self-measurement which doesn’t requirement others’assistance
5.The most advanced lateral LCD(liquid crystal displaydesign which better enables the
operators to control the distance between the probe and the cornea and read the values on the display a new innovative move.
6.Itis small and easy to take along.You can use it anywhere without environmental
restrictions to continually monitor the ocular pressures
7.The use of disposable probes avoid the cross infection
8. Usually patient could use it in an upright gesture,in the cases
when patients could not stand upthe lying gesture is also allowed
9.Wireless data printing(require another photocopier)10.Built-in storage function which can store some ten sets
of data for review or printing.
11.The time and date could be set for review.
12.The use of AA battery is safe and less energy-consumed.
13.Use integrated circuits in order to work more stable and longer.
The working mechanism ofFA800 rebound tonometer
Rebound tonometer,also known as impact tonometer, adopts an innovative sensing rebound technology.The probe will be magnetized when being inserted into the tonometer and generates N/S poles.An transient current in the solenoids of the device(lasting about 30 milliseconds) produces an transient magnetic field that causes the maqnetized probe to
move toward the cornea at0.2m/s(homopolar repulsion principle)The probe bounces on the anterior surface of the cornea.slowina down and reboundingIf the ocular pressure is increased,the deceleration of the probe increasesand the duration of the impact decreases. The electrical control switch monitors the solenoid voltage caused by the rebound of the maqnetized probes,and the electronic signal processor and the microsensor calculate the deceleration of the probe after impacting the cornea.Finallytheintegrated information is converted into ocular pressure readings
Rebound tonometer is an electric measuring type pressure gauge which converts the pressure into the voltage or current signal
through the physical characteristics of the metal. Tonometer can obtain the measurement data within 0.1 seconds
Applicability:
1. Used in tonometery tests byophthalmologists
optometrists,general physician,professional health advisors
2. Better for patients with dementiamobility problems
and childrenin the measurementofcornealedema opacity or uneven corneal surface.
3.Handy for glaucoma patients in measuring ocular pressure at home.
Usages:
1.Turn on the tonometer and install the probe
2. Move the machine close to the eyes and adjust the distance
3. Gently press the button and obtain the single measurement values and average values in several times.*Short Measuring Time,Only seconds*Reduce the check time for glaucoma*Capable of storing the ocular data
of some ten patients. TÜVRheinland
