Abstract
The invention relates to a measuring instrument for the measurement of an existing pain or a feeling of nausea of a patient. The measuring instrument induces pain in an arbitrary body part of said patient, by supplying an electrical current. The measuring instrument provides a current increase into said body part, until said induced pain is experienced by the patient as being as great as the existing pain/nausea. The current is supplied from a current source arranged in the measuring instrument via wires (H, I) and electrodes (C, D), said electrodes being applied onto that part of the body in which pain is to be induced. When the pain induced is experienced to be as great as the existing pain/nausea, the body part is removed from the electrodes, whereupon a pain value is registered and shown on a display (F). (FIG. 6)
Claims54
An apparatus for assessing the level of an arbitrary first sensation experienced by a person, the first sensation being compared to an induced physical sensation, the apparatus comprising:
- a stimulator configured to supply a physical stimulus of an electrical current from a current source connected by a wiring with a first and a second electrode to said person to induce a physical sensation in said person;
- a stimulation level control device configured to control the level of said physical stimulus;
- an activator mechanism configured to activate a supply of said physical stimulus;
- a deactivator mechanism actuateable by said person and configured to deactivate an assessment of said level of an arbitrary first sensation;
- a registration device configured to register a sensation level value dependent on the supplied physical stimulus and corresponding to said first experienced sensation in response to a deactivation by said person of said assessment when the induced physical sensation is perceived to be comparable to the first experienced sensation;
- and
- a support structure for said electrodes, the electrodes being positioned on said support structure such that the electrodes are capable of being pressed against a body part of said person to achieve a closed current circuit for the electrical current stimulus.
An apparatus for assessing the level of an arbitrary first sensation experienced by a person, the first sensation being compared to an induced physical sensation, the apparatus comprising:
- a stimulator configured to supply a physical stimulus of heat from a heat source connected with a first and a second heat element electrode to said person to induce a physical sensation in said person;
- a stimulation level control device configured to control the level of said physical stimulus;
- an activator mechanism configured to activate a supply of said physical stimulus;
- a deactivator mechanism actuateable by said person and configured to deactivate an assessment of said level of an arbitrary first sensation;
- a registration device configured to register a sensation level value dependent on the supplied physical stimulus and corresponding to said first experienced sensation in response to a deactivation by said person of said assessment when the induced physical sensation is perceived to be comparable to the first experienced sensation;
- and
- a support structure for said heat element electrodes, the heat element electrodes being positioned on said support structure such that the heat element electrodes are capable of being pressed against a body part of said person to achieve a predetermined application of the heat to the body of the person.

- a stimulation level control device configured to control the level of said physical stimulus;
- an activator mechanism configured to activate a supply of said physical stimulus;
- a deactivator mechanism actuateable by said person and configured to deactivate an assessment of said level of an arbitrary first sensation;
- a registration device configured to register a sensation level value dependent on the supplied physical stimulus and corresponding to said first experienced sensation in response to a deactivation by said person of said assessment when the induced physical sensation is perceived to be comparable to the first experienced sensation;
- and
- a support structure for said stimulus electrodes, the stimulus electrodes being positioned on said support structure such that the stimulus electrodes are capable of being pressed against a body part of said person to achieve a predetermined application of the stimulus to the body of the person.
