Abstract: A hot-wire anemometer comprises a probe. The probe has a probe head disposed at an end thereof. The probe head has an elongated narrow hole or a plurality of round holes being provided with at least a metal wire segment extending in an axial direction of the probe head to enlarge a contact area between the metal wires and a fluid. According to an average temperature of the larger area, a more accurate wind velocity is measured.

Abstract: A lancing device includes a front cap detachably capped on a front side of a shell, a lancet, and a lancet holder linearly movably mounted in the shell for securing the lancet. The lancet holder is configured to provide one or multiple guide portions at the outer perimeter thereof. The front cap has one or multiple guide tracks located at an inner wall thereof corresponding to the stroke of the guide portion of the lancet holder. Thus, under the guidance of the guide track, the lancet and the lancet holder can be moved smoothly with minimized vibration to reduce the sense of pain suffered by the user.

Abstract: A lancing device includes a main body and a replaceable lancet. A front cover is detachably mounted to a front end of the main body and formed by a shell and a positioning member connected inside the shell for receiving the lancet. A shock absorber is mounted in between the shell and the positioning member. When the lancet is fired by a built-in percussion unit of the main body to move forward, the front end of the lancet collides with a stop portion of the positioning member, and the lancet stops movement and instantaneously retracts. Meanwhile, most or all of the vibrational energy generated when the front end of the lancet collides with the positioning member can be absorbed by the shock absorber. In this way, the vibration in the process of the blood sampling can be reduced to further minimize the pain felt by the testee.

Abstract: A magnetic field generating seat cushion includes a cushion body, and a magnetic field generator, which is mounted in the cushion body, including a main circuit board, an inner coil and an outer coil. The inner and outer coils are electrically connected to the main circuit board. The main circuit board and the outer coil can generate an alternating current to go through the inner coil, causing the inner coil to generate an alternating magnetic field. In comparison to the outer coil, the inner coil has a high number of turns and a relatively smaller area for generating a high strength magnetic field in a small area with low electricity consumption to intermittently oxygenate the body tissues of a person sitting or lying on the cushion body, thereby generating a massage-like effect and achieving muscle-relaxing, blood-circulating and metabolism-enhancing effects.

Abstract: A pH-meter capable of measuring conductivity and dissolved oxygen at the same time is composed of a gauge and three probes. Three power sources and three measuring circuits are mounted to the gauge. The detectors of the probes include a pH detector, a conductivity detector and a dissolved oxygen detector. Each of the probes is independently connected with the gauge via a transmission cable to be independently supplied with electricity and the signals of two probes are independently transmitted by electric insulation. Thus, the detecting elements can measure the pH value, conductivity, and dissolved oxygen at the same time with interference with one another.

Abstract: A dry and wet bulb psychrometer consists of a first temperature sensor, a second temperature sensor, a water tank, a water absorbing member, a computing circuit and a display screen. The water absorbing member is connected to the second temperature sensor and dipped in water in the water tank. The computing circuit is electrically coupled with the first and second temperature sensors for computing a humidity value by using the temperature values sensed by the first and second temperature sensors and displaying the computed result on the display screen for reading by a user. Thus, the dry and wet bulb psychrometer is convenient for application to provide high-precision level measurement.

Abstract: A waterproof pH meter includes a main unit, a probe, which includes a probe electrode and a signal processing circuit, and a waterproof signal transmission line electrically coupled between a main circuit in the main unit and the signal processing circuit of the probe. When measuring a solution, a potential signal generated by the probe electrode is amplified by the signal processing circuit and then transmitted to the main unit through the waterproof signal transmission line for reading by the user. As the design has a better capacity in bearing noise interference, the signal transmission line can be selected from a regular waterproof cable instead of a BNC material.

Abstract: A pressure detection device for use in an electronic manometer includes a container for receiving a liquid, a first conduit for the air to pass through, and a second conduit for the liquid to flow therein. When the air having the same pressure as that of a pressure transducer is directly or indirectly drawn from the electronic manometer through the first conduit into the container, the liquid in the container flows into the second conduit due to the pressure difference. In this way, get a difference between the liquid level of the second conduit and that of the container and compare the difference with a user's blood pressure measured by the electronic manometer to detect whether the measuring result of the electronic manometer is accurate or not.

Abstract: The electrode test strip is used with an electrochemical sensor for measuring an analyte in an aqueous sample, e.g., glucose in blood. The electrode strip includes an elongated electrode support, a first and second electrode on the support, a slotted dielectric layer, a screen and a slotted cover layer, all disposed atop each and atop the electrodes in the support. The dielectric layer and the cover layer are typically adhesively attached (the adhesive layers further define the slot). The slot is open to the terminal end of the test strip and the cover. The screen, interposed in the slot, has a porosity between 10%-40% to control analyte flow and volume in the slot and over the test area defined by electrode legs. Further refinements include utilizing a surfactant on the screen.
