摘要:
The present invention relates to a multiwell plate having a series of wells, each well having an inner bore, an open top and a bottom, the bottom being sealed with a liquid permeable filter, and an insert contained within the inner bore of each well, each insert having an outer dimension the same or larger than that of the inner bore and a through bore of a dimension less than that of the outer dimension of the insert. The use of inserts allows one to take a standard one-piece plate design with a heat sealed membrane and arrange for a universal plate format. The insert may act as a base for an extension plate that can be adhered, heat sealed or overmolded over the plate top and insert top to form a deep well plate. The plate conforms to the Society of Biological Standards Microplate Standards. Additionally, the inserts may be configured to give one a different well diameter (smaller, tapered, etc), to include various media such as chromatography resins, to include multiple layers of membrane and the like. A variety of inserts may be used in the same plate to create a minilab on a plate that is capable of conducting several steps of a process on the same (e.g (e.g. filter, wash, bind, elute, label, etc).

A take-off needle comprises a hollow lance having a distal end adapted to perform a insertion operation, said hollow lance being connected to at least one pipe provided with a spigot for it to be connected to a tube, and comprising a body for holding the hollow lance and pipe relative to each other such that the spigot projects from the holding body, said needle further comprising two flanges held on respective sides of and spaced from the holding body by virtue of a spacer disposed between each flange and the holding body, said flanges extending in a longitudinal direction from the spigot to the vicinity of the proximal end of the hollow lance, the width of each flange being greater than the width of the portion of the holding body facing the flanges.
摘要:
A sensor device intended to be implemented at the vicinity or inside a nuclear magnetic resonance apparatus, and more particularly on a patient inside the canal of the magnet of a magnetic resonance imager (MRI). The device includes at least two non-metal electrodes intended to be applied to the skin of a patient, and an electro-optical conversion, amplification and filtering module for the electric signals received from the heart by the electrodes. The module is arranged in a shielded casing forming a Faraday cage, and optically connected to a display and/or monitoring apparatus. A support body made of non-magnetic material carries the electrode and the shielded casing containing the module.
摘要:
A general surveillance monitor to monitor the vital physiological signs of patients undergoing examination by nuclear magnetic resonance imaging is constructed such that each functional module of the monitor is individually protected from the electromagnetic environment and high frequency parasitic currents and such that the control assembly is a computer system without any magnetic storage.

The method includes the step of positioning the device on a sheath (94) having, for each latching tab (7), a portion adapted to be housed between this tab and a cylindrical wall of the device; the step of making the sheath enter between each tab and the cylindrical wall until means preventing the withdrawal of the tabs are released; and the step of moving the two bodies (2,3) away from each other. The instrument has, in addition to the sheath (94), a guidance slide (77).

The contact lens comprises a central optical zone and a peripheral zone for fastening the lens. For centering said lens the peripheral zone comprises two stabilizing bosses which are disposed on the horizontal stabilization axis of the lens. For large palpebral openings it may be preferable to use two pairs of bosses, whereby each pair comprises two bosses, disposed symmetrically to said axis of stabilization. For multifocal corrections it is possible to use a third boss, disposed on the vertical axis of the lens. These stabilizers allow a perfect centering of the lens, hindering its rotation and the use of very thin lenses.
