Transducer for the simultaneous measurement of different physiological quantities

A device for the simultaneous measurement of at least two different physiological quantities of a human or animal body and being connectable to signal processing electronics, comprising:

• a measuring head containing a transducer for measuring a first physiological quantity and a contact surface means for engaging with said human or animal body;
• a first one of a pair of electrodes being located at the contact surface means to contact with said human or animal body together with said contact surface means and having means for electrically coupling to said signal processing electronics;
• a second one of said pair of electrodes being attached to the measuring head outside said contact surface means thereof and having connection means for electrically coupling to said signal processing electronics;
• a bipolar plug connection having first and second poles, said bipolar plug being removably fitted to said measuring head, said first pole being coupled to said second one of said pair of electrodes for coupling to said signal processing electronics by connection to said second one of said pair of electrodes and said second pole having means for electrically coupling to said signal processing electronics;
• and
• an adhesive electrode body having two insulated juxtaposed electrodes each of which are adapted for contact with said human or animal body, said adhesive electrode body including a further removable bipolar plug connection having third and fourth poles, said third pole being coupled to one of said juxtaposed electrodes and said first pole and said fourth pole being coupled to the other of one of said juxtaposed electrodes and said second pole.
