Abstract
Abstract A therapeutical apparatus using electric field comprising a main electrode vertically arranged at the head side of mat on which a patient lies or accommodated in a housing arranged at the head side of a bed on which the patient lies. A further electrode fixedly or movably arranged at the foot side of the mat or the bed, insulating cords connected with the electrodes, respectively, so as to enable voltage to be applied to the electrodes, a checking point arranged adjacent to the main electrode and including a conductive plate, and a detecting means arranged between the conductive plate and the main electrode and rendered operative when the checking point is touched by his finger of the patient.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
238 words
A therapeutical apparatus using electric field comprising a main electrode arranged at the head end of a support surface on which a patient lies, a further electrode arranged at the foot end of said support surface, insulated conductors, connected to the respective electrodes, for enabling a voltage having an AC component to be applied to the electrodes, a monitoring means for enabling monitoring of the continuity of an electrical circuit formed by said main electrode and the said conductors connected thereto when a voltage is applied to said main electrode, said monitoring means being disposed adjacent to the main electrode and being connected in a circuit which includes said electrodes and which is completed through the body of the patient when the patient contacts the further electrode and said monitoring means, said monitoring means comprising a conductive plate and an insulating plate connected to the face of the conductive plate and adapted to be contacted by the patient, and a detecting means, operative respective to the monitoring means being touched by the patient, arranged between the conductive plate and the main electrode, said detecting means comprising an indicator device which is energized when a said voltage is being applied to said main electrode and which is not energized when a voltage is not being applied to said main electrode to thereby enable faults to be detected in the said circuit formed by the main electrode and the conductors.
Claim 2
Dependent Claim
238 words
A therapeutical apparatus using electric field comprising a main electrode arranged at the head end of a support surface on which a patient lies, a further electrode arranged at the foot end of said support surface, insulated conductors, connected to the respective electrodes, for enabling a voltage having an AC component to be applied to the electrodes, a monitoring means for enabling monitoring of the continuity of an electrical circuit formed by said main electrode and the said conductors connected thereto when a voltage is applied to said main electrode, said monitoring means being disposed adjacent to the main electrode and being connected in a circuit which includes said electrodes and which is completed through the body of the patient when the patient contacts the further electrode and said monitoring means, said monitoring means comprising a conductive plate and an insulating plate connected to the face of the conductive plate and adapted to be contacted by the patient, and a detecting means, operative respective to the monitoring means being touched by the patient, arranged between the conductive plate and the main electrode, said detecting means comprising an indicator device which is energized when a said voltage is being applied to said main electrode and which is not energized when a voltage is not being applied to said main electrode to thereby enable faults to be detected in the said circuit formed by the main electrode and the conductors.
Claim 3
Dependent Claim
55 words
A therapeutical apparatus according to claim 1 wherein the main electrode is detachable from the apparatus and is housed in a casing attached to the upper portion of an L-shaped supporting frame, said supporting frame including horizontal portion adapted to be inserted under a mat disposed on the supporting surface on which the patient lies.
Claim 4
Dependent Claim
42 words
A therapeutical apparatus according to claim 1 wherein one of the electrodes is insulatingly supported in a housing arranged at the head end of a supporting surface on which the patient lies, a mat being laid under the patient on the bed.
Claim 5
Dependent Claim
73 words
A therapeutical apparatus according to claim 4 further comprising mounting means for movably mounting the electrode provided at the head end of the support surface, said mounting means including a pair of spaced, parallel wall plates and a movable support member for mounting the said electrode for movement along the upper edges of said wall plates, and including a pair of grooved wheels which ride on the upper edges of the wall plates.
