Title: Device for Measuring Arterial Blood Pressure Under Variable Ambient Pressure.
Inventor: KOSTROV PAVEL MIKHAILOVICH
IPC: A61B5/0235
Filed: 1967-06-12
Abstract: 1,194,251. Measuring blood pressure. SAMOSTOYATELNOE KONSTRUKTORSKOE TEKHNOLOGOCHESKOE BJURO BIOLOGICHESKOGO; I FYZIOLOGIOHESKOGO PRIBOROSTROENLYA MINISTERSTVA ZDRAVOOKHRANENIA SSSR. 12 June, 1967, No. 16797/67. Heading A5K. A blood pressure measuring device for use under variable ambient pressure e.g. under water, has an inflatable band 13, which is inflated through a pressure reducer 2 at a constant preset pressure under the control of a solenoid valve 3. and a valve device 7, 16 by means of which the pressure in the band is vented through a valve 21 at a rate independent of ambient pressure and means for monitoring the pressure in the band. The measuring device may be built into a respiratory diver's helmet or suit and operated electrically from a control panel at the water surface. When the valve 3 is opened gas passes from the pressure reducer 2 through a chamber 8 to inflate the band 13 and through a normally open valve 22 and a chamber 9 to a chamber 10 which is vented through a bleed valve 16. Whenever flow of gas through the valve 22 causes the pressure in the chamber 10 to rise above ambient pressure (pressure in suit or helmet), the valve 22 is closed by a membrane 23. The pressure in the chamber 10 is subsequently released through the valve 16 and permits opening of the valve 22 by a spring 24. In use of the device the valve 3 is closed when the desired maximum pressure is reached in the band 13. The gas in the chamber 9 and an intercommunicating membrane 20 gradually falls in pressure due to the alternate opening and closing of the valve 22. Gradual collapse of the membrane 20 causes a vent valve 21 to open to an extent dependent on the rate of fall of pressure in the chamber 10 so that the pressure in the band 13 is released. The arterial oscillations indicative of systolic and diastolic pressures in the band are transmitted by a microphone 19 and a pressure responsive device 6 to the surface control panel. In an emergency the system may be vented through a solenoid valve 4 operated from the surface control panel or through a plug cock 5 operated by the wearer. The bleed valve 16 comprises a bellows 26 which is subjected to ambient pressure and which operates a piston 27 in such a manner that as ambient pressure falls or rises more or fewer openings 28 are exposed, respectively for the exhaust of gas from the chamber 10 via a filter 14.

Material is fed from a sealed hopper and a supply funnel or magnetically shaken spout to a screw conveyer 10 rotated within a hollow shaft 5 on which is mounted for rotation a driven sleeve 4 carrying a hollow rotor 1. This rotor, together with a co-operating concentric rotor 2 rotated in the opposite direction by a shaft 6, is surrounded by a stator 3. On the opposing, slightly coned, faces of the rotors are clamped concentric, interfitting rings of pyramid-shaped hollow teeth 16 in the bases of which lead washers 23 are held to balance the rotors, the teeth 16 at the periphery of the rotors being longer than those nearer the centre, and the rotor whose teeth are further from the axis being rotated at less speed than the other rotor. The tooth faces which may be roughened in file fashion are so inclined as to set up a partial vacuum behind each tooth. Material distributing vanes 19 are mounted at the centre of the rotor 1. One or more circularly arranged series of spacedly superposed sieving blades 26, 27 are clamped to the peripheral part of each rotor; these blades are toothed as at 28, may be more widely spaced towards the periphery and may have their cheeks rasped. The stator 3, which may be loosely mounted, has a series of sieve blades 32 spaced round its periphery, and is encased by an asymmetric cover 33 which receives the ground product for discharge through an aperture 34 which may open into a vacuum. The blades 26, 27 may be replaced by sieves rotated at the same speed as the rotors. The machine may be provided with cooling arrangements or work in a low temperature chamber, and the crushing may take place in a vacuum. The Specification as open to inspection under Sect. 91 also stated that the teeth 16 could be dispensed with and be replaced by blades similar to the blades 26, 27 or by other blades, that the machine could be arranged with its shaft vertical and a gravity or suction feed to the machine used, that one rotor could be used whose teeth co-operate with teeth on a stator, and that the blades 26, 27 could each be in the form of a complete circle. This subjectmatter does not appear in the Specification as accepted.
