Abstract:
A video laryngoscope has a handle and a groove on one side of the handle. The groove is used for guiding a guide wire when the larynogoscope is placed in a patient's mouth. A video camera located near the end of the handle is used to view the area around the glottis. When the guide wire is properly positioned near the glottis, the upper part of the guide wire is disengaged from the groove so as to allow an endotracheal tube to be slipped over the guide wire and to be inserted into part of the trachea through the glottis. When the tube is properly inserted for intubation, the guide wire is removed from the tube. An illuminating light source such as an LED lamp can be installed at the end of the handle to provide illumination for the video camera.
Abstract:
The current invention involves a desorption corona beam ionization source/device for analyzing samples under atmospheric pressure without sample pretreatment. It includes a gas source, a gas flow tube, a gas flow heater, a metal tube, a DC power supply and a sample support/holder for placing the samples. A visible corona beam is formed at a sharply pointed tip at the exit of the metal tube when a stream of inert gas flows through the metal tube that is applied with a high DC voltage. The gas is heated for desorbing the analyte from solid samples and the desorbed species are ionized by the energized particles embedded in the corona beam. The ions formed are then transferred through an adjacent inlet into a mass spectrometer or other devices capable of analyzing ions. Visibility of the corona beam in the current invention greatly facilitates pinpointing a sampling area on the analyte and also makes profiling of sample surfaces possible.
Abstract:
A mass spectrometric analyzer and an analysis method based on the detection of ion image current are provided. The method in one embodiment includes using electrostatic reflectors or electrostatic deflectors to enable pulsed ions to move periodically for multiple times in the analyzer, forming time focusing in a portion of the ion flight region thereof, and forming an confined ion beam in space; enabling the ion beam to pass through multiple tubular image current detectors arranged in series along an axial direction of the ion beam periodically, using a low-noise electronic amplification device to detect image currents picked up by the multiple tubular detectors differentially, and using a data conversion method, such as a least square regression, to acquire a mass spectrum.
Abstract:
A light source device includes a first heat dissipation structure, an LED module, a heat energy convertor and a fan. The first heat dissipation structure includes a heat dissipation base, a first fin group attached on a top surface of the heat dissipation base. The LED module is attached on a bottom surface of the heat dissipation base of the first heat dissipation structure. The heat energy convertor is thermally connected to the heat dissipation base of the first heat dissipation structure through heat pipes, and configured for changing heat energy generated by the LED module into kinetic energy. The fan is disposed over the first fin group and driven by the heat energy convertor.
Abstract:
Stable and uniform distribution of gel beads or other particulate material, dispersed in a liquid medium can be obtained by including a density-reducing agent within the gel beads to provide the particle with a desired bulk density, for example a density close to that of the disperse liquid medium. Suitable density control can prevent migration due to gravity leading to settling in storage. Gel beads formulated with agar are suitable for use in cosmetics and for inclusion in cosmetics formulating processes which may employ modestly elevated temperatures. Attractive and novel cosmetics bead suspensions are described. Additional to cosmetics, pharmaceutical, foodstuff and other applications are disclosed. Examples of suitable density-reducing agents include very low density hollow polymeric microspheres and temperature-sensitive expandable thermoplastic microspheres.
Abstract:
A method of introducing ions into an ion trap and an ion storage apparatus are described. Introduction means are used to introduce first ions into an ion trap through an entrance aperture to the ion trap. An operating condition of the introduction means is adjusted to cause second ions, of different polarity to the first ions to be introduced into the ion trap through the same entrance aperture.

Abstract:
A gas-liquid separation apparatus includes an inlet pipe for transferring liquid with gas dissolved therein and a separating pipe for separating the gas from the liquid. The separating pipe has a spiral-shaped guiding member therein. The separating pipe extends from the inlet pipe and is in alignment and communicating with the inlet pipe. An outlet pipe extends from a joint of the inlet pipe and the separating pipe and communicates with the separating pipe, for transferring therein the liquid after the liquid has been degassed by the spiral-shaped guiding member in the separating pipe. A gas storage device communicates with the separating pipe and outside for collecting the gas from the separating pipe and discharging the gas to the outside.
Abstract:
A gas-liquid separation apparatus includes a container and a separating pipe located in the container. The container includes an annular wall and two lids covering two ends of the wall. The container has a cavity surrounded by the wall and the two lids. An inlet extends through one lid and an outlet extends through the other lid. The separating pipe is disposed in the cavity of the container and in communication with the inlet and the outlet of the container. A plurality of apertures is defined in a body of the separating pipe and in communication with a space inside the separating pipe and the cavity of the container. The liquid with gas dissolved therein enters into the separating pipe via the inlet of the container. The liquid is degassed by the separating pipe. The de-gassed liquid exits the separating pipe via the outlet of the container.
