Definitions
- This invention is directed to methods and apparatus for treating patients and, more particularly, to a bed useful for treating patients by facilitating the body' s own healing processes to stimulate cellular regeneration and thereby speed up healing of ailments suffered by the patients.
- low-level m the range of no more than about 2 milli -Teslas: ⁇ 2mT and preferably as low as 10 micro-Teslas : ⁇ 10 ⁇ T, or lower
- magnetic fields work to stimulate cellular regeneration, and that this regeneration is enhanced when the body is kept at a regulated and constant temperature .
- a device for treating hypothermia with a magnetic field was disclosed n United States Patent No. 4,685,462.
- This device includes two spiral induction coils coupled with an RF generator through an automatic frequency tuning system comprising capacitors and induction coils.
- the coils are placed in a non-conducting cylinder which is an element of its casing.
- One of the coils is fed from the RF generator by a signal of a frequency tuned to the resonance frequency of the device, another by mutual induction.
- the device is used at a frequency of 2 MHz to 20 MHz, and is intended only to warm a patient who has been subjected to extreme cold, such as a diver submerged in near freezing water. It does not disclose use of magnetic fields to increase cellular regeneration.
- Another device for medium and high frequency electromagnetic field treatment, includes a pulse generator, a modulator, an amplifier, a band filter and a current regulation circuit.
- generated pulses are modulated by their duration or timing, and are amplified by means of power selectors.
- the amplified signal is applied to the patient through a filter by means of induction coils or electrodes.
- a signal from the patient is supplied to the device where a regulation system sets the value of rated current which excites the coils and electrodes.
- a device for effecting the local, alternating electric and magnetic field of low frequency is disclosed in Polish patent document No. 171930.
- This device is provided with sensors of the three components of the terrestrial and local magnetic fields, connected with low-pass filters and a microcontroller at the output of which there is connected a pulse generator with three coils coupled thereto, incorporating an input multiplexer with inputs that are sensors and an output multiplexer. Those sensors are connected in parallel between the input multiplexer and the output multiplexer through low-pass filters.
- This device is used to determine the parameters of all components of the terrestrial and local magnetic fields and of the parameters of the electric field of the biological organism. It detects and signals the occurrence of cyclotromc resonance for specific ions which affect the biological processes of the organism, but is not itself intended for use in treating patients .
- European patent document No. 0995463 describes a method and a device for the generation of an electromagnetic field which affects biological processes in living tissue, especially in the human body, by means of a pulsating magnetic field.
- An electric signal consisting of many discrete pulses having a frequency of from 1 Hz to 1000 Hz is generated and supplied to a device which then generates an electromagnetic field.
- single pulses are grouped in pulse groups and the duration of each pulse group ranges from 0.25 second to 1.2 second.
- This device does not disclose the use of long-term exposure to a low-frequency magnetic signal for treating a patient.
- the disadvantage of all those known devices is that they apply relatively high magnitude magnetic fields in the intensity range of from 1 mT to 10 mT, or they generate a magnetic field in one direction only.
- Another disadvantage of known devices is that they affect only a specific selected part of the human body through large values of magnetic induction causing excessively rapid stimulation of metabolic processes, while at the same time affecting healthy organs with unnecessarily strong, and therefore potentially harmful, magnetic fields. Exposure of the human body to strong magnetic fields for extended periods of time is known to cause cellular damage, and so high-intensity magnetic field generating devices are not suitable for use over long periods, such as convalescence from serious long-term illnesses or injuries.
- the invention is a method and apparatus for stimulating cellular regeneration m a body of a patient, including an electromagnetic field generator for generating a low-frequency, low-intensity magnetic field, and a support for maintaining the body of the patient in the magnetic field during treatment.
- the frequency of the magnetic field is preferably in the range of from about 40 Hz to about 80Hz.
- the intensity of the magnetic field is less than about 2mT, preferably less than 20 ⁇ T, and most preferably less than lO ⁇ T.
- a thermoregulator may be provided to maintain the patient's body at a constant selected temperature for treatment. The thermoregulator controls heating elements to heat the patient if the patient' s body temperature is too low, and controls cooling apparatus, such as fans, air conditioning, or cooling coils in the support, for cooling the patient if the body temperature is too high.
- FIG. 1 shows a device in accordance with the invention, shown in exploded perspective
- Fig. 2 shows the device of Fig. 1 in the context of a system employing the inventive method
- Fig. 3 shows a perspective of an alternate embodiment of the frame of a device in accordance with the invention
- Fig. 4 shows a planar view of a coil used to generate a magnetic field in the devices of Figs. 1-3.
- a means 18 for generating a magnetic field is disposed below supporting surface 16, so that the patient is disposed in the magnetic field generated by magnetic field generator 18, but preferably not in direct contact with generator 18. Often, portions of generator 18 may be hot, and so for the safety and comfort of the patient, direct contact therewith should be avoided.
- Supporting surface 16 may be detachable and of any sort providing comfortable support to the patient, such as a conventional mattress, a thin fabric sheet which is preferably air permeable and suspended from frame 14 as by springs 19, or a specially adapted mattress in which the magnetic coils are disposed. It is also possible supporting surface 16 may be eliminated and frame 14 is made to be water tight. Frame 14 is then filled with a fluid, such as water, as shown in Fig. 3, and the patient is partially immersed and suspended in the water, to avoid contact with a solid surface.
- a fluid such as water
- Frame 14 is preferably open at the top, and has four sides, 20, 22, 24 and 26. Sides 20, 22, 24 and 26 and supporting surface 16 are preferably lined with an insulating material to minimized heat loss. It is preferred that supporting surface 16 has a thin metal thread 30, most preferably made of copper, woven into it. Preferably, thread 30 should cover at least 2/3 of the length of the longer side of supporting surface 16 so that when the patient is laying on supporting surface 16, thread 30 is disposed proximate the patient, regardless of patient size. Thread 30 is connected to an electrical ground 32 and is used to carry excess electrostatic charge away from the patient.
- a set of coils 34 is disposed proximate supporting surface 16 and is selected to produce an electromagnetic field having a frequency in the range of from about 40 Hz to about 80 Hz, and preferably in the range of from about 50 Hz to about 60 Hz.
- Coils 34 are energized with alternating current of no more than 24 volts from a current source 36 (Fig. 4) in conventional fashion.
- the strength of the magnetic field is controlled by an adjuster 37 which, in response to input, alters the intensity of the current passing through coils 34 from current source 36.
- coils 34 are arranged generally parallel to one another (except at their longitudinal ends, which are joined by U-shaped portions) proximate the entire support surface 16.
- coils 34 are placed on or between two fabrics or materials which are thermoconductive, allowing for the dissipation of heat therefrom.
- the density of the turns of winding of individual coils is selected so that the value of the magnetic induction provided thereby is within the range of from about 1.2 ⁇ T to about 10 ⁇ T on the edges frame 14, and preferably should not exceed about 2.6 ⁇ T in the vicinity of the patient.
- thermoregulator 38 which comprises one or more conventional temperature sensors 40 placed in close proximity to the body of the patient, for example in supporting surface 16, in a cover 42 disposed on top of supporting surface 16, or on the body of the patient.
- a temperature selection means 44 such as a dial or digital input, is connected to thermoregulator 38 allow the patient or treating physician to select a comfortable or treating temperature.
- the temperature is selected within the range of from 65°F to about 100°F.
- the precise temperature is not believed critical, but it is believed most desirable that the patient be maintained at a substantially uniform temperature over his entire body, with the possible exception of the head, which is generally maintained outside of cover 42, for ease of breathing. This temperature should be substantially constant over time.
- Sensors 40 transmit the value of the current body temperature of the patient to thermoregulator 38, which controls the temperature near the patient by switching an air chamber heating/cooling unit 46 on or off. Although four heating/cooling units 46 are shown, fewer or more units may be used. At the same time, coils 34 may be switched on or off to regulate the generation of the magnetic field from generator 18, to control heat generated thereby. It is preferred that the body temperature of the patient be maintained constant with a variance of no more than about 0.4°F from the selected temperature. If the body temperature rises more than 0.4°F, the patient is cooled by heating/cooling units 46, while if the body temperature falls more than 0.4°F below the desired temperature, the patient is warmed by heating/cooling units 46.
- Heating may conveniently be accomplished by providing heating/cooling elements 46 in either or both of support surface 16 and cover 42, as, for example, by an electric blanket-type mechanism, as is well-known.
- external heating elements such as convection heaters, space heaters, hot air blowers, and the like may be provided.
- Cooling may likewise be accomplished in conventional fashion, by providing cooling coils in either or both of support surface 16 and cover 28, or by providing an ambient cooling element 48, such as an air conditioner, fan, ceiling fan or other known mechanism for cooling an environment.
- an ambient cooling element 48 such as an air conditioner, fan, ceiling fan or other known mechanism for cooling an environment.
- a patient lying on support surface 16 is subject to the electromagnetic field generated by means 18, with concomitant regulation of temperature m this area, thereby subjecting the patient to natural thermal regulation and intensification of physiological metabolism processes, producing a distinct improvement in his physical condition.
- the invention can be used for long-term hospital patients (in which case the inventive device could be used as a hospital bed) , or for patients being treated at home, during their normal sleep cycle (in which case the inventive device could be used as a bed) .
- the magnetic field be cycled on and off in two hour intervals to maintain the body in a constant state of flux, which is currently believed to be most efficacious in treatment of a patient, but this is not a necessary component of the treatment process. Longer or shorter cycling periods, including a constant "on" condition, may be employed, as desired.
