  • Patent number: 5070859
    Abstract: A laryngoscope (1) is equipped with a dynamometer in order to be able to measure and record the force expended per unit time by an anesthetist during the vacating and keeping unobstructed of a path in the oral and pharyngeal cavity for the introduction of a tube into the trachea. The dynamometer comprises pressure elements arranged in the spatula contact surface (17) and, respectively, in the proximity of the spatula joint. By means of this measurement, an objective judgement can be made with regard to the anesthetist's skill; on the other hand, the pharmaceuticals utilized for the intubation procedure can be objectively documented by measured values with regard to their pharmacological properties, such as, for example, the production of rapid and intense muscle relaxation.
