A self-contained, presterilized trocar assembly, with an outer cannula and cutting stylet, is just long enough to penetrate the skin of the throat and the cricothyroid membrane and reach the posterior third of the lumen of an average adult trachea. Its short length and self-limiting penetration preclude damage to surrounding tissues. The cannula retains its intratracheal position by a flaring of its distal end after insertion and during a final stage in the deployment. This device enables an una...

A method for sterilizing a male by coagulating an anatomical element using an instrument having a body with two members adapted for closing towards each other and holding therebetween an anatomical element, and a waveguide constructed to emit electromagentic radiation at a predetermined microwave frequency suitable for coagulation of an anatomical element, the waveguide disposed on at least one of the body members, comprising the steps of holding an anatomical element between the body members cl...

Methods and apparatuses are featured for preconcentrating immunological reactants prior to their contact and reaction to enhance the rate of reaction for separating reacted and unreacted reactants and, also, to increase the sensitivity at the detector-measuring system. The preconcentration of the reactants finds particular use in immunoassays, where very often an immunospecies is very dilute causing a time consuming and/or insensitive assay. The preconcentration and separation are accomplished w...

Method of and apparatus for doing work characterized by the steps of establishing respective hot and cold zones within a constant volume chamber; providing a flow path intermediate the zones and encompassing a caloric energy storage means for extracting heat from gases that are hotter and for delivering heat to gases that are colder as the respective gases are flowed therepast; separating the respective hot and cold zones by reciprocally movable member that is movable longitudinally of its cylin...

A system for performing the desired transaction when the customer follows a specified procedure comprising a sequence of steps includes an electronic visual display unit for displaying a message and an illustration at the same time, a plurality of function buttons arranged in the vicinity of the display unit, a clerk key to be manipulated by the clerk and a memory having stored therein the terms, messages and illustrations to be displayed on the display unit. For customer processing, the display...

An apparatus for performing a work function on a workpiece comprising a stationary base, a rotatable base mounted on the stationary base, a hydraulically actuated mechanism for rotatably displacing the rotatable base relative to the stationary base, a lower arm member pivotally mounted on the rotatable base, a hydraulically actuated mechanism for angularly displacing the lower arm member relative to the rotatable base, an upper arm member pivotally mounted on the lower arm member, a hydraulicall...

In an automatic performing apparatus, an amount of change in a motion of a moving element provided in a baton is detected, and the detected change amount is converted into an electrical signal. A tempo clock signal generator provided in the apparatus is driven by the electrical signal to produce a tempo clock signal for reading out musical data preset in a memory. A volume level of a musical tone is set by a control section on the basis of the data of a peak level of the change amount in the mot...

A process for performing sample analyses wherein reagents are filled portionwise into closed containers that comprise cells and carry codes identifying the reagent contained therein. Cells required for different analyses are placed in a rack together with a sample container containing the sample. A code identifying the sample is applied to the rack. The codes on the cells and the code on the rack are read with the same reading unit.

An improved apparatus and method for performing an emergency cricothyrotomy comprising a tracheostomy device which can be inserted into a patient's neck without danger of puncture of the posterior wall and which permits insertion of an airway tube without popping out of the device from the incision in the patient's neck or penetrating the posterior wall. An airway tube can be quickly and easily substituted for another airway tube of differing internal diameter without the need for redefining the...
