    摘要： A fluid particle counter comprising an inlet jet tip producing an air flow, a strip laser diode producing a laser beam, and a beam shaping system that includes an aspheric collimating lens, an achromatic spherical lens, a cylinder lens, and a series of cascading apertures. A retarder rotates the polarization so that the TE mode is along the direction of fluid flow. The optical system is designed so that along the flow axis the laser beam is single mode, while the multimodes due to the strip laser are constrained to the dimension perpendicular to the flow. The beam is pinched to a 35 micron waist and has a Gaussian profile along the flow direction which permits locating the beam within 3.5 mm of the flow tip while preventing stray light scattering from the tip. The beam profile along the axis perpendicular to the flow is closer to a square wave than a Gaussian. The particle counter output is substantially free of all noise except noise created by light scattered from molecules of the fluid, even for volumetric particle counters.

    摘要： The present invention relates to a sealing wafer (1) adapted to be arranged in a stoma receiving hole (5) of a base plate (2) comprising an attachment platform extending from an outer edge adapted to be attached to the base plate towards an inner edge defining a through-going hole (17) for receiving a stoma, the sealing wafer further comprising at least a first urging part extending transversely from the proximal surface facing towards the user during use of the attachment platform and wherein the first urging part is resilient in the direction transverse to the proximal surface. This provides a sealing wafer which is particularly suitable for use with a stoma around which the skin has an uneven curvature, such as a retracted stoma wherein the stoma has pulled back resulting in a crater-like area.

    摘要： Provided are devices and methods for monitoring flow rate in aerosol particle counters. The particle sensor has a particle counter, a flow measurement orifice comprising a differential pressure sensor for measuring differential pressure (DP) across the flow measurement orifice during particle sensor operation and a critical flow orifice. A vacuum source pulls ambient gas through each of the particle counter, flow measurement orifice and critical flow orifice. An atmospheric pressure sensor measures atmospheric pressure (AP) and a bench pressure sensor measures pressure in the particle sensor (BP). The output from the sensors is used to identify a flow condition, such as by a monitor operably connected to each of the differential pressure sensor, atmospheric pressure sensor and bench pressure sensor. In this manner, deviation in flow rate from a target flow rate is readily monitored without the need for expensive sensors or other flow-controlling components.
