| 摘要 |
<p>The present invention concerns a method and a device for measurement and assessment of oedema, especially with regard to a combination of the two types of oedema called pitting oedema and brawny oedema. The method comprises the steps of reading the frequency of a freely and in resonance oscillating sensor, the application of the in resonance oscillating sensor against an oedema to a certain depth of depression and the continuous reading of the force of application and the resonance frequency of the in resonance oscillating sensor. The device comprises a measuring head that is adjustably supported by a stand and exhibits partly a freely and in resonance oscillating sensor (6) for making a resonance system together with the oedema when applied to it, partly a means of reading the current resonance frequency of the sensor, partly means (5) for measuring the force with which the sensor is applied to the oedema. Information is hereby obtained concerning the degree of stiffness as a measure of brawny oedema through read frequency shift and the degree of displaced fluid obtained as a measure of pitting oedema through measurement of decay of force.</p> |
