Publication number: 20090069864Abstract: Quantity and time for medical operation are measured after starting the medical operation (step S1). Parameters in a parameter protection mode and parameters in a standard mode are compared so as to determine whether or not contents in the parameters coincide and whether or not five minutes passes (step S2). If five minutes do not pass, it is detected whether or not a power supply switch is turned off (step S4). If it is not turned off, the operation returns to the step S1 so as to determine whether or not the power supply is turned off within five minutes in steps S3 and S4 while measuring the quantity and the time for the medical operation. If five minutes passes without turning off the power supply, data for the quantity and the time for the medical operation are loaded in a memory (step S5). After that, the operation is completed.Type: ApplicationFiled: November 6, 2008Publication date: March 12, 2009Applicants: ITO CO., LTD., HIROSE ELECTRIC CO., LTD.Inventors: Toshimasa Sakagami, Hirotsugu Sato, Takashi Nemoto

Publication number: 20040267333Abstract: An method and method for generating an electrical signal for use in biomedical applications, including two timing-interval generators, each optionally driving a multistep sequencer; analog, digital or hybrid means for combining the resulting timed signals into a complex electrical signal; optional filtering means for blocking direct current, removing selected frequency components from the resulting signal, and/or providing voltage step-up if needed; and conductive means for coupling the resulting signal to a human or animal body, food, beverage or other liquid, cell or tissue culture, or pharmaceutical material, in order to relieve pain, stimulate healing or growth, enhance the production of specific biochemicals, or devitalize selected types of organisms.Type: ApplicationFiled: June 24, 2004Publication date: December 30, 2004Inventor: James W. Kronberg

Publication number: 20040243197Abstract: A pulse generating apparatus has two like output channels that apply generated pulse signals of selected characteristics to two electrodes attached to a strap, each electrode receiving a different signal. The strap is attached to the foot so that the electrodes are positioned to stimulate with an electrical signal the abductor hallucis muscle of the foot to correct an imbalance due to overpowering by the adductor hallucis muscle. The signal strengthens the abductor hallucis muscle so that eventually it regains strength sufficient to counter balance the imbalance effect of the stronger adductor hallucis muscle and alleviate the bunion condition. The electrical signal generator generates signals that are pulses that are adjustable in frequency, modulation, pulse width and amplitude with modified square waves.Type: ApplicationFiled: June 17, 2004Publication date: December 2, 2004Inventor: Bassem M. Demian

Publication number: 20040236391Abstract: A living body stimulating apparatus capable of giving extensive therapeutic effects and softer feeling of stimulation. Rectangular wave pulse groups S containing a plurality of pulse density modulated higher frequency components or on-pulses than a rectangular wave pulse are applied repeatedly from conductor elements 24 to a human body. As a human body has a capacitive impedance, softer stimulation can be applied to the human body as compared with a rectangular wave having the same current and frequency. Furthermore, a pause period between on-pulses is varied by a stimulus generator means 8, so that a charging current to an equivalent electrostatic capacity of a human body is supplied little by little so as to slowly increase a charged quantity. As a result, cenesthesia of softer stimulation can be obtained.Type: ApplicationFiled: July 22, 2003Publication date: November 25, 2004Applicant: Techno Link Co., Ltd.Inventors: Tatsuyuki Kobayashi, Takashi Izumi

Publication number: 20040230256Abstract: An electronic acupressure aide and stimulating device implemented using a hand-held or palm-held electronic computing device or another computing device which may be a designated unit. The electronic acupressure aide and stimulating device allows a practitioner to apply a pulse sequence to a set of predetermined acu-points such as those related to acupressure, acupuncture, trigger points or Jin-Shin Jyutsu, to name a few. A displayed chart related to the acu-points identifies the health condition and the pulse sequence.Type: ApplicationFiled: May 15, 2003Publication date: November 18, 2004Inventor: Catherine Lin-Hendel

Publication number: 20040230253Abstract: Quantity and time for medical operation are measured after staring the medical operation (step S1). Parameters in a parameter protection mode and parameters in a standard mode are compared so as to determined whether or not contents in the parameters coincide and whether or not five minutes passes (step S2). If five minutes do not pass, it is detected whether or not a power supply switch is turned off (step S4). If it is not turned off, the operation returns to the step S1 so as to determine whether or not the power supply is turned off within five minutes in steps S3 and S4 while measuring the quantity and the time for the medical operation. If five minutes passes without turning off the power supply, data for the quantity and the time for the medical operation are loaded in a memory (step S5). After that, the operation is completed.Type: ApplicationFiled: May 12, 2004Publication date: November 18, 2004Inventors: Toshimasa Sakagami, Hirotsugu Sato, Takashi Nemoto

Patent number: 6795728Abstract: An apparatus and method for minimally invasive treatment of deep subcutaneous fat deposits in lieu of cosmetic surgery is disclosed. The apparatus comprises a high voltage pulse generator connected to two or more needle electrodes at least one of which is configured for placement deeply under the skin in a treatment site of the patient's body. High voltage pulses, delivered to the electrodes, create an electric field that kills subcutaneous fat cells.Type: GrantFiled: February 19, 2003Date of Patent: September 21, 2004Assignee: Minnesota Medical Physics, LLCInventors: Victor I. Chornenky, Ali Jaafar

Patent number: 6792315Abstract: An apparatus for providing therapeutic electric current to a treatment site of a patient is disclosed, which provides two oscillating or pulsing electric alternating currents, of frequencies which differ from each other by as little as 1 Hz and up to about 250 Hz, but each being of frequency at least about 1 KHz. The apparatus requires only one feed electrode adapted to feed the electric currents to selected feed sites on or beneath the epidermal or mucous surface of the patient, and only one return electrode adapted to be positioned on or beneath the epidermal or mucous surface of the patient, locally to the treatment site. The apparatus includes a feedback subsystem to detect impedance changes in the patient and accordingly adjust the output of the apparatus.Type: GrantFiled: April 21, 2003Date of Patent: September 14, 2004Assignee: Biowave CorporationInventors: John Carter, Bradford Siff
