Abstract: The invention relates to an illuminated optical laryngoscope formed by an assembly, longitudinally defining a first straight segment and a second curved segment and comprising a main body (1) that is inserted into a tubular protective case (2). The curved segment of the main body (1) is formed by successive segments hinged to one another.

Abstract: A device (1) for the ventilation of a human being or animal which comprises a dome (2) having a cavity (2a), which dome (2) is attached to a laryngeal ring (3) for sealing the human being or animal's internal airways, at least one oxygen tube (4) that connects to the cavity (2a) of the dome (2), for allowing oxygen or gases to enter or leave the human being or animal's internal airways and at least one laryngeal aspiration tube (5), different from the oxygen tube (4), that also connects to the cavity (2a) of the dome (2), for allowing air and/or secretions to leave the human being or animal's internal airways.

Abstract: The invention relates to an optical light laryngoscope with a built-in fluid extraction device, of the type comprising two independent conduits. One of the aforementioned conduits is equipped with optical means for viewing the inside of the larynx while the other conduit is used for introducing the endotracheal tube into the larynx. The inventive laryngoscope also comprises a built-in fluid extraction device which is used to withdraw fluids from the mouth in order to optimize the view when the endotracheal tube is being inserted into the patient in a convenient, safe and hygienic manner.

Abstract: This invention refers to an optical-light emitting laryngoscope, consisting of a body (1) that contains two independent ducts (3, 4), one of which is free while the other contains optical elements (12), with a straight section followed by a section that is anatomically curved, the end of which is finished by three guide walls (16) for the oral-tracheal tube that has been inserted, while it is possible to observe the movements of the same in a real image through a magnification lens (6) and the optical elements (12), the optical duct being protected by a transparent shell (30), achieving correct positioning of the oral-tracheal tube (15), this invention being designed for oral-tracheal intubation, in operating theaters, emergency wards and out-patient facilities, etc. The body of the laryngoscope (31) may contain a single duct (4) which contains the optical elements (12).

Abstract: The catheter is of the type provided with a needle and a cannula for the introduction thereof by means of only one hand into the blood conduits of a living being's body, preferably a human body, and is composed of three independent assembled bodies. The first of them is a hollow cylinder open on its rear end and having a cannula joined to its front end, in addition to guide means assembled with the guide means of a second body or casing. The cannula is open on its upper, front and rear part, and its front end is provided with a needle joined to it with semicircular section along the majority of its length. A perforated and hollow plunger is introduced inside of the cylinder along its entire length, with a flap and pusher on its upper part, its lower end being provided with a connection.

Abstract: A syringe and its method of use, comprising two bodies; the first body or cylinder provided with a support surface at its end, and a second body or rod with pusher elements, which is introduced in the prior cylinder. The syringe can be used by means of a single hand and it is possible to perform the two actions of a syringe, sucking and injection, by changing the position of the fingers.
