Description
TENS AI'PLICATION DEVICES
TYus invention relates to transcutaneous nerve stimulation and more specifically relates to devices far applying transcutaneous nerve stimulation for physiotherapeutic purposes.
Transcutaneous nerve stimulation, commonly referred to as TENS is the application of a controlled amount of low electrical currents to stimulate nerves and/or muscle tissues in a patient for treating numerous physiological problems such as muscle and joint pain and inflamation. The currents niay be provided in a steady flow or in electrical impulses of various wavelength frequencies. The electrical currents primarily stimulate the nerve for the body to produce natural endorphiris to block the perception of pain and also physically cause the muscle tissues at the area of application to tighten and relax repeatedly, and thus increasing the blood circulation to enhance the natural curing process. The TENS currents are provided by a generator and the currents are delivered with application probes to the inflicted locations of a patient's body. The free end of the currents application probes is commonly in the form of a flexible inductive composite pad which must be attached to the patient's body with conductive adhesive gel and/or adhesive 1:apes in order to deliver the current to the patient's body.
However, the curing process is not efficient if it is relying solely on the TENS stimulation.
Another problem in employing flexible TENS probes is that residual adhesive often remains on the patient's skin, which is difficult to clean off. Also, due to the natural skin secretion which hinders the affinity of the adhesive to the skin, the probes usually do not adhere securely i n place particularly after repeated use. The adhesive probes are also particularly problematic to apply on skin area having body hair, as the probes would be difficult to remove from the patient without causing great discomfort and pain after the TENS
treatment with the ,I ,,r adhesive inherently pulling out hair from the skin area.
It is a principal object of the present invention to provide TENS application devices which are effective in providing efficient TENS treatment to a patient.
It is another object of the present invention to provide TENS application devices which include beneficial functions for providing enhanced TEN treatments to a patient.
It is another object of the present invention to provide TENS application devices having additional. beneficial components for providing supplementary physiotherapy to a patient.
It is yet another object of the present invention to provide TENS application devices which may be located on selected areas of a patient's body without using adhesive.
It is still another object of the present invention to provide TENS
application devices convenieritly usable to deliver TENS treatment to a patient through the palms or sole.
O1:her objects and advantages of the present invention will become apparent from the following detailed description of the preferred embodiments thereof in connection with the accompanying drawings wherein Figure 1 a perspective front elevation view of the TENS application device according to the preserit invention for providing enhanced TENS treatment.
Figure 2 is an enlarged isolated sectional side elevation view of the basic device according to the present invention along section line II-II in Figure 1..

-3-I.,r 1 I I n =11.-CA 02585209 2007-04-17 embodiment for illustration purposes. The carbon fiber is preferably made of bamboo charcoal which has a porous structure and it possesses the characteristics of odor absorption, anti-bacteria, humidity adjustment, ultra infrared ray generation that can promote blood circulation, and negative ion generation, which can enhance the TENS treatment process. The upper layer 15 may be made of a flexible plastic or rubber compound and the like. The contact layer 16 may be made of a soft foam material having a coarse and liquid absorbent characteristics with a soft outer surface 17. A plurality of magnetic elements 18 are embedded in the outer flexible layer 15. The application probe 11 may be conveniently placed with its outer surface 17 of the body contact layer 16 in contact with the inflicted location on the body of a patient for the TENS treatment.
Electrically conductive adhesive or gel may be provided on the outer surface 17 for attaching the probe 11 intimately to the patient. Alternatively, adhesive tapes may be employed for ensuring the attaclvnent of the probe 11 to the body. The intensity of the currents can be varied by adjusting the TENS generator in the common manner. The magnetic elements 18 provide beneficial magnetic field to the treatment area to enhance the TENS treatment by increasing the blood flovv to the inflicted area of the body.
Figure 3 shows another embodiment of the application probe 11 of the present invention in which a heat generating layer 19 is provided in its laminated structure.
The heat generating layer 19 may be located between the top layer 15 and the current conductive carbon layer 14 with or without an insulating spacer layer 20 provided between the carbon layer 14 and the heat generating layer 19. Figure 3 shows the exemplary embodiment of having the insulating spacer layer 20 so that a warming heat is evenly transmitted the body contact layer 16.

-4-,, Ir 1 iIF
electrical supply cord may be combined with the connecting cord 12 as shown.
During treatment the heat generating layer 19 is actuated to apply additional heat to the inflicted area of the patient to enhance the TENS. The heat will further enhance the blood circulation in the inflicted area for intensifying the natural physiotherapeutic process of the TENS currents. The positions of the TENS current conductive carbon layer 14 and the heat generating layer 19 may be alternatively located with the heat generating layer 19 located adjacent to the skin contact layer 16 so as to provide higher heat to the inflicted area of patient.
Fi;gure 4 shows another embodiment of the TENS probe of the present invention which is in the forrn of a rigid composite disk. The disk may have a round or other convenient shape for easy handling. This embodiment is a combination of that shown in both Figures 2 and 3. The device 10 in this embodiment is provided with a rigid outer plastic casing 22 having an opening 23. The laminated structure of the various layers is similar to that shown in Figure 3. The exemplary illustration shows the construction with the heat generating layer 19 located adjacent to the body contact layer 16. A plurality of magnet elements 18 are also imbedded in the body contact layer 16. Additionally, a plurality of protruding points 24 extending outwards from the body contact layer 16 may also be provided on the outer surface 17. A
composite electrical connecting cord 12 for supplying both the TENS current to the conductive carbon layer 14 and the heat generating layer 19 is shown. The device 10 in this embodiment, may be held by hand to press its body contact layer 16 tightly against the inflicted area of the patients body. The protruding points 24 provide a physical massaging excitation action in addition to the enhanced functions of the magnet elements 18 and heat generating layer 19 in the TENS
treatment.
