An oral fluid collection and transfer device comprises a collection device (10) and a test cartridge (100). The collection device includes a frame or chassis (14), and an absorbing pad (12) for absorbing oral fluid and which is secured around part of the frame with part of the frame protruding from the pad. A collapsible cover (16) covers the absorbing means and has apertures (68) forthe ingress of oral fluid into contact with the absorbing pad. Acap (18) covers the part of the frame protruding from the absorbing pad. The cap and the cover latch together to surround the frame and the absorbing pad. The device also includes a fluid adequacy indicator (20) in the form of an electrical circuit with an LED (66) which is completed when the absorbing means has absorbed a predetermined volume of oral fluid. The test cartridge (100) has a collection chamber (110) to allow insertion of the collection device into the test cartridge. A test strip (150) is used to for test the oral fluid for the presence of analytes. The collection device (10) is located at a fixed location relative to the test cartridge (100) within the collection chamber(110), in which location the absorbing pad (12) undergoes a controlled degree of compression, thereby transferring a predetermined volume of oral fluid from the absorbing pad to the test strip. A transportation vial may also be provided for the secure transportation of a sample of oral fluid to a laboratory for test verification. After initial testing, the collection device (10) is inserted into a transportation vial (180) wherein the remaining oral fluid contained within the collection device (10) is transferred to a sample vial (190) containing a preservative substance to prevent degradation of the sample during transportation. The collection device (10) and transportation vial (180) are repackaged and sealed with a tamper proof seal before being returned to a laboratory for confirmation or further tests.

A manually-actuated device for the deliver of a volume of liquid which includes an outlet through which liquid is in use delivered and a cover member which is movably disposed relative to the housing between a first position in which the cover member at least partly covers the outlet and a second position in which the cover member acts as a lever which in use is acted upon by a user to actuate the delivery device.

The invention relates to a device of the type adapted to deliver fluids, notably medicaments, under pressure. The device comprises a container 1 of variable volume in the form or shape of a pouch or flexible receptacle of generally cylindrical shape with longitudinal pleats 2 containing the fluid under pressure to be delivered and equipped with an actuator C permitting to open a valve 15 a , 15 b to enable the delivery of said fluid, the whole being located inside a container 4 capable of resisting to an elevated internal pressure, the internal volume of the latter container comprised between its wall and the container of variable volume being filled with a neutral gas under a pressure sufficient to exert on the container of variable volume a pneumatic constraint sufficient to permit the delivery of the therein contained fluid when the above-said valve permitting said delivery is operated by the aforementioned actuator C.

1. Syringe intended for the ultra-ligamentary injection of liquid products, especially anaesthetic products, of the type composed of a body the forward portion of which, to which the injection needle is fitted, serves as housing for a container of the said liquid product, constituted by a glass tube the rear extremity of which is closed by a plug (7) of rubber or analogous material, while the rear portion of the body serves as guide for a piston (6) actuated by a rack (4), in such manner that when the operator operates the syringe, the piston progresses forward step by step, thrusting the said plug forward into the interior of the container, and consequently the liquid product into the injection needle, the piston (6) being terminated, at its forward extremity, by a head (12, 12') of a diameter substantially equal to the internal diameter of the container (8), characterised in that the head forwardly presents a concavity causing migration of the material of the plug (7) towards the axis in the advance of the piston (6).

The system has a cross arm (1) with a plate (12), and a motorized system to plunge a sampling device (5) into soil or material to be sampled. A lower end of a vertical rod (50) of the device crosses a drilling in the plate. The drilling of the plate (12) is located in an axis of a ring (31) of a support device (3) and in a drilling of a plate (32) of the support device. An independent claim is also included for a method to implement a system for using a device that takes samples in humid soil or a material of granular or powdery composition.

Equipment (10) for the preparation of a hot beverage comprising a boiler (10) capable of containing a liquid component of the beverage, for example water, a collection container (14) and means (22, 20, 28) defining a delivery path for the liquid component from the boiler to the collection container. The equipment also comprises valve means (40) located along the delivery path for the liquid component comprising a plug (44) which can move between a position in which the delivery path is closed and one in which it is open and means (70, 72; 74, 76; 78) to immobilise the plug in the open position. These means are arranged in such a way that they can be activated and deactivated by a force exerted in the direction of movement of the plug.

The device has a measuring tape (4) attached by clamping to a concave surface (3) of a carrier body (1). The extent of the concave surface is defined by detent surfaces (6,7) on each end of the measuring tape. At least one of the detent surfaces is adjustable using an adjusting device (9), so that the spacing of the detent surfaces can be matched to the length of the measuring tape.

A cartridge (101) for separating a desired analyte from a fluid sample includes a sample port (103) and a sample flow path extending from the port through the body of the cartridge. The sample flow path includes at least one flow-through component (122), e.g. filter paper or a microfabricated chip, for capturing the desired analyte from the sample as the sample flows through the cartridge. The cartridge also includes an elution flow path for carrying elution fluid through the component (122) to release captured analyte from the component into the elution fluid. The elution flow path diverges from the sample flow path after passing through the component (122). Flow controllers (41A and 41B) direct the remaining fluid sample into a waste chamber (139) after the sample flows through the component (122) and direct the elution fluid and eluted analyte into a reagent chamber (141) and reaction chamber (143). The continuous-flow design of the cartridge permits the rapid processing of a fluid sample that is larger in volume than any interactive region within the cartridge, allowing increased sensitivity in the detection of low copy concentrations of analytes, such as nucleic acid. A preferred embodiment relates to a device for lysing components of a fluid sample, the device comprising inter alia, an ultrasonic transducer.
