| 20080300503 | Method and system of monitoring respiratory signal by radio - A method and system is provided for monitoring a respiratory signal by radio. The method includes the steps of: converting a change in electric resistance, which is caused by a change in abdominal circumference measured through a rubber waistband that is made of conductive rubber and is mounted on a lower garment of a testee during respiration, into a voltage signal, performing A/D conversion on the voltage signal, and transmitting the converted digital signal to a short distance by radio using a wireless communication protocol for ZigBee; and receiving the respiratory signal transmitted by radio, transmitting it to a computer unit by wire through an RS-232 port that is a serial communication port, and enabling a tester to monitor the respiratory signal through a screen. | 12-04-2008 |
| 20080312557 | Method and system for measuring urinary flow rate - Disclosed are a method and an apparatus capable of efficiently and precisely measuring a urinary flow rate by using a general purpose pressure sensor with a low price, instead of a conventional expensive weight sensor, even without a conventional funnel. According to the method and the apparatus, water pressure of urine accumulated in a vessel is transferred to an external pressure sensor through a pressure transfer pipe, the received water pressure is converted into electrical signals through the pressure sensor, the electrical signals are amplified through a bridge amplifier, the amplified analog signals into digital signals (water pressure signals), the water pressure signals are converted into volume signals through an interface with an analyzer, and urinary flow rate signals are acquired by differentiating the volume signals, in which the electrical signals are voltage signals corresponding to volume signals. | 12-18-2008 |
| 20090101148 | CONTINUOUS POSITIVE AIRWAY PRESSURE DEVICE BY CONTROLLING THE PRESSURE IN THE FACE MASK - A CPAP device includes an air stream generator for generating positive pressure, a face mask connected to the air stream generator through a flow supply catheter, a pressure sensor measuring pressure in the face mask, a control circuit controlling the air stream generator, and a pressure detection pipe having a first side and a second side. The pressure sensor is connected to the second side of the pressure detection pipe to measure pressure of the detection hole formed at the first side of the pressure detection pipe and outputs the measured pressure value to the control circuit. The control circuit distinguishes average positive pressure from pressure caused by spontaneous breathing of patient according to values of the pressure in the face mask, which are input from the pressure sensor, and controls a speed of the air stream generator such that preset positive pressure is supplied to the patient. | 04-23-2009 |
| 20100106216 | PROBE FOR ELECTRIC STIMULATOR HAVING VARIABLE VAGINAL ELECTRODE - A probe for an electric stimulator having a variable vaginal electrode constantly maintains the contact resistance by adjusting the diameter of the electrode corresponding to the user. Electrodes are provided on front and rear parts of a body of the probe, respectively. The electrodes are provided in a circular arrangement such that the electrodes move up and down. A rotating handle is formed at a side of the body such that the handle rotates at the side of the body. A shaft coupled to the handle rotates when the handle rotates, so a cam plate coupled to the shaft rotates, and the rotated cam plate pushes the electrodes, thereby expanding or reducing a diameter of the electrodes. | 04-29-2010 |
| 20100142773 | METHOD AND SYSTEM FOR ACCURATELY MEASURING VERY SMALL VOLUME OF BLOOD - A method and system for accurately measuring a very small volume of blood is used for accurate evaluation of an amount (volume) of blood collected by a lancing device, evaluation of a scientific very small amount of blood, and so on. The method includes the steps of collecting the very small volume of blood, absorbing the very small volume of collected blood into an absorption medium, drying the absorption medium, scanning the dried absorption medium using an image scanner connected to a computer to obtain a digital image, and calculating the very small volume of blood from the digital image using an analysis program. | 06-10-2010 |
| 20100152684 | METHOD AND SYSTEM FOR MEASURING URINARY FLOW RATE - A method and system for measuring a urinary flow rate minimizes impact noise caused by urine to measure the urinary flow rate using a plurality of load cells when prostatic hypertrophy is diagnosed. The method includes measuring an amount of urine collected into a container using a plurality of load cells, extracting and averaging urinary flow rate signals from the measured results, and removing the impact noise from the urinary flow rate signals, converting the urinary flow rate signals into digital signals through an A/D converting circuit, and outputting the digital signals using a personal computer or a microprocessor analyzer which is interfaced with the A/D converting circuit. | 06-17-2010 |
