23 Order code GONIOMETER & TORSIOMETER SENSORS 6.1 General description The comprehensive range of goniometer and torsiometer sensors are intended for quick, simple, and accurate measurement of joint movement in multiple planes. The sensor is connected to the Measurement Unit through Preamplifier. Goniometer Sensor Preamplifier (MEGO) Connector Terminals Preamplifier Adapter for models SG and Q Figure 6-1. Goniometer / Torsiometer with Preamplifier Single axis goniometer Single axis goniometer permits the measurement of angles in one plane along the axis X-X. This goniometer is intended mainly for the measurement of finger and toe flexion/extention. Telescopic Endblock Fixed Endblock X Z Y Y Z X Linear movement along Z-Z Figure 6-2. Single axis goniometer 23 Mega Electronics Ltd 2009

24 ME6000 Sensor guide for Twin axis goniometers Twin axis goniometer permits the measurement of angles in two planes along axis X- X and axis Y-Y. The outputs of the two channels are independent of linear movements along axis Z-Z. Telescopic Endblock Fixed Endblock X Z Y Y Z X Linear movement along Z-Z Figure 6-3. Twin axis goniometer Single axis torsiometer Single axis torsiometer permits the measurement of rotations in one plane, e.g. forearm pronation/supination. Telescopic Endblock Fixed Endblock Figure 6-4. Single axis torsiometer 6.2 Connecting the sensor In general, there are four types of joint sizes: finger and toe; wrist; elbow and knee; and back. There are no fixed rules governing which size of sensor is most suitable for a particular joint; this depends on the size of the subject. The sensor must be capable of reaching across the joint so that the two endblocks can be mounted where least movement occurs between the skin and underlying skeletal structure. In certain circumstances more than one size of sensor will be appropriate. Mega Electronics Ltd

25 Order code Figure 6-5. Examples for placing the sensor Connect the sensor as following: 1. Place the sensor over the joint you intend to measure. 2. Secure the endblocks to the surface (for most cases it is recommended to use standard medical double sided adhesive tape). 3. Connect the sensor terminals to the Preamplifier. The red dot mark on the terminals should face the arrow mark on preamplifier (figure 6-6). Figure 6-6. Connecting the sensor to the Preamplifier In goniometers and torsiometers type SG and Q, an adapter (type A100) is needed (figure 6-7): Figure 6-7. Connecting sensor type SG and Q to the Preamplifier to MEGO-1 goniometer preamplifier. SG anf Q type sensors can be connected to MEGO-3 preamplifier without adapters. N O T E! Use GTF Adapter when connecting to the Preamplifier Cable to ME channels Measurement Unis. 4. Connect the Preamplifier to the Measurement Unit. 5. Turn on the Measurement Unit. 6. Adjust the signal in MegaWin. 25 Mega Electronics Ltd 2009

26 ME6000 Sensor guide for 6.3 Signal Adjustment 6.4 Cleaning In order to guarantee the accuracy of the sensor it is recommended to perform two point check prior to the angular measurement. This can be achieved by zeroing the sensor against known straight edge (e.g. a ruler) and displacing it by a known angle (usually 90 ). Following, you should calibrate the signal in MegaWin PC Software by setting the minimum and maximum levels. On how to calibrate the signal in MegaWin, please refer to MegaWin User s Manual. If the results of the two point check are not within the required accuracy then the Sensor needs to be further calibrated in relation to its Preamplifier. On how to perform this procedure please refer to the Technical Manual or contact you local dealer. The equipment can be calibrated, for example, by the hospital maintenance staff according to the instructions given in the Technical Manual. You can clean the sensor by wiping it with cloth damp with soapy water. To disinfect the sensor use disinfectant instead of soap.! CAUTION Do not use solvents, acidic or strong alkaline materials. Also, do not sink the Sensor or the Preamplifier in fluid. When cleaning or disinfecting, the sensor must be disconnected from the Measurement Unit. 6.5 General instructions Handle the sensor carefully. Be careful not to drop the sensor on hard surfaces. Do not wash the sensor with water and avoid extremely high humid conditions. Recommended maximum use of 30 minutes in humid place (relative humidity over 80%) without proper protection (e.g. water proof kit). Before cleaning the sensor shall be disconnected from the device Do not expose to temperatures under 0 C /32 F /273K or above 50 C / 122 F / 323K without proper isolation. Do not open any of the sensor parts. When disconnecting the sensor from the Measurement Unit, pull at the connector. Do not pull at the cable and do not rotate the connector. When not in use place the sensor in its box. During usage the minimum permissible values of bend radius must be observed all times. Mega Electronics Ltd
