Optical device () for blood analysis is in particular designed for the counting and differentiation of leucocytes in an automatic blood analysis apparatus and includes a light source () of the electroluminescent diode type in order to illuminate a blood sample () circulating in an optical tank.

Optical measurement method for counting and/or differentiating leucocytes

Apparatus () includes a device () for moving at least one compartment () in the apparatus, the compartment forming a support for tubes (), which apparatus further includes elements () for taking a specimen of a product contained in the tubes, the movement device () including elements () for guiding the compartment during movement of the compartment and further including stirring members () for the guiding elements, the movement device being mounted on a chassis () of the apparatus.

Apparatus for handling tubes, in particular an automatic blood analysis apparatus

A sampling device includes a body, a needle, a sealing element and an element for feeding and removing a liquid. The needle has at least one groove located between the sealing element and the sampling end of the needle. The sampling end has a sampling hole opening out on a lateral wall of the end. The sampling device leakage problems encountered in the conventional art to be overcome while at the same time resolving the problems of placing the inside of a tube containing a product to be analyzed at atmospheric pressure.

Sampling device and method usable in an analysis automated device

A flow-through tankis suitable for an optical devicefor the counting and/or differentiation of leucocytes in an automatic blood analysis apparatus. The tank has an analysis zone, in which the section of the tank has at least one transverse dimension between 1 and 5 millimeters. It can advantageously be produced, at least partially, from an injected plastic material.

A syringe block () includes a plurality of syringes () and a collector (), the syringes each having a suction volume, and the collector includes electromagnetic valves. First tubes directly link the electromagnetic valves to the internal volumes and second tubes extend from the electromagnetic valves towards the containers for the sample and/or other liquids, at least one of the syringes being an air pump (). The syringe block can be used as a support for various components used for the operation thereof, and can be arranged in a climatic condition reproducer. One such syringe block is especially adapted to be used in a liquid analyser, the air pump being used especially to take a sample and/or to drain and clean different recipients containing a sample.

An apparatus is disclosed for counting and determining at least one leucocytic sub-population, comprising a case for injecting a flow of sample to be analyzed inside a measurement tank through which a light beam passes, comprising internal and external nozzles for sleeving the sample by means of a pressurized liquid. Electrodes for the resistivity measurements of the leucocytic sub-population are component elements of the injection case. Units for collecting and processing the signals delivered by the optical sensor and the electrodes are also provided.

Apparatus for counting and determining at least one leucocytic

The diaphragm comprises an outer flexible part and a central part in which is overmoulded a rocking lever. The rod portion of said rocking lever is at right angles to the diaphragm plan and intended to be received in a recess of a sliding sleeve. The diaphragm rocking lever assembly is linked to an axle passing through the rocking lever and bearing on the valve body. The microvalve may be used in chemical and medical analysis devices.

Switching microelectrovalve having a single diaphragm

A device is provided for automatically taking liquid from a bottle, including a stopper piercing assembly with a mobile block serving as support for a sample taking needle which moves vertically along guide columns under the action of a cylinder, a rinsing receptacle being fixedly mounted on the guide columns and traversed by the needle.

The invention provides an automatic drain device with membrane for pneumatic circuits. A flexible membrane (11) which separates the opening (2) of a jar (1) from a drain pipe (6) is precurved in a top position against this opening and against a skull-cap (8) against which it bears, which skull-cap then closes a communication orifice (14) provided on one side of the membrane. Under the action of the pressure in the jar, the membrane moves down to come to bear against a discharge end-piece (5) freeing, during this movement, orifice (14) and making drainage possible.
