Abstract

In the process of generating high frequency magnetic fields for treating living organisms, an apparatus for limiting undesirable interference and disturbance that may be caused by electromagnetic radiation from said fields.

Claims

1. A field producing apparatus for high frequency treatment of bodily parts of living organisms for the purpose of healing thereof comprising:

a) a high frequency generator (sender) (5) for the production of a high frequency current at a sender level of the sender;

b) a treatment capsule (8), which possesses at least one magnetic coil (9) for the generation of a high frequency field strength which is correlated to the sender level (5), said treatment capsule (8) having a first treatment position for orderly placement on a bodily part of a living organism for the high frequency treatment, and a second load-free position when not in a treatment position, the load free position being a load-free condition wherein an unacceptable high frequency disturbance can be radiated into an ambient environment;

c) a controller (12) with a regulator for the operational regulation of said sender level;

d) an indicator (29) sensing switch for comparing the sender level of said sender (5) to the field level of the treatment capsule (8) for establishing a set ratio value, wherein said ratio value indicates the field level for the capsule (8) in the treatment position and in the load-free position;

e) said indicator (29), when detecting the load-free condition, issues a shifting signal for switching of the field producing apparatus (1) to a safety position so that said field producing apparatus (1) is placed in one of a shutoff condition or a reduced level condition until the ratio value of the sender level and field level are reduced to a specified ratio value so that no unacceptable high frequency disturbance level can be emanated by the treatment capsule under the load-free condition; and

(f) a field level sensor (10;

26), assigned to the treatment capsule (8) for determining the field level of the magnetic coil (9), said field level sensor being electrically connected to the indicator (29) and further including a sender level sensor (24) for detection of the sender level which is connected to the indicator (29) to enable a comparison between the sender level and the field level so that, from the comparison, the load-free position of the capsule can be determined.

2. A field producing apparatus in accordance with claim 1, wherein the field level sensor (10) is included in the treatment capsule (8) and an electrical value of one of the electrical current and electrical voltage of the magnetic coil is detected and electrical value is directed through a signal wire (11) to the controller (12), in which the indicator (29) is located.

3. A field producing apparatus in accordance with claim 2, including a directional coupler (26) located on an output of the field producing apparatus to determine a standing wave measurement for computation of a standing wave ratio for determining whether the capsule (8) is in the treatment position and has a damped high frequency transmission by tissue absorption, or is in the load-free condition wherein the high frequency is not damped by high frequency transmission, and with the detection of a load-free condition, a specific control is sent to a level weakener which reduces the sender level.

4. A field producing apparatus in accordance with claim 3 including a micro controller (18) co-acting with said controller (12) to which the field level, as well as the sender level is delivered, said controller (12) generating an adjustment signal (25) based on a comparison of the field level and the sender level, and including a sender weakener assembly (4), containing a resistance weakener (6) to which the adjustment signal is delivered by indicator (29), so that, in a case of the field level being greater than the sender level, the adjustment signal will cause the sender level and field level to be reduced and, in a case of the field level being lower than the sender level, the resistance weakener will increase the field level.

5. A field producing apparatus according to claim 4 including a field level determinator for limiting the field level and preventing an unacceptable high frequency disturbance level during operation of the treatment capsule (8).

6. A field producing apparatus in accordance with claim 5, wherein the field level determinator includes an initialization mode wherein the sender level is controlled to deliver a low, predetermined, starting sender level following initial activation, either in the first treatment position or the load-free position of the capsule (8), so that a high frequency disturbance level during the initial activation can be prevented;

and including a threshold means for indicating a threshold value bordering between the treatment position and the load-free position, and including an alarm that upon overstepping the threshold value, said alarm is activated to advise a service person in regard to a failure of a placement of the capsule on organic tissue and upon an understepping of the threshold value, the initial activation of the capsule placed on organic tissue is terminated, and the controller (12) is released from the initialization mode to begin normal operation.

7. A field producing apparatus, in accordance with claim 6, including a timer device for activation of start-up of the treatment so that the treatment may be automatically shut down following a specified duration of the treatment and restarted in the initialization mode.

8. A field producing apparatus in accordance with claim 7, wherein said micro controller has an indicator for controlling the treatment capsule for operation.

9. A field producing apparatus in accordance with claim 8, including a high frequency oscillator (2) for producing a high frequency signal at a predetermined value in the range of 100 to 200 MHz and including means for modulating the high frequency signal in response to one or both of a predetermined low-frequency and a predetermined high frequency.

10. A field producing apparatus in accordance with claim 9, wherein the predetermined value is about 150 MHz.
