摘要： An examination device for a heart. An afterload device connected to the aorta provides a counterpressure by an annular space delimited between a rigid cylinder and an elastic tube inserted in the rigid cylinder. The annular space comprises a compressible medium, such as air, nitrogen gas or carbon dioxide and is connected to a reservoir providing a predetermined pressure corresponding to a diastolic pressure. The reservoir is connected to the annular space via a restriction and a back-flow valve. During diastole, the annular space is inflated by the reservoir and provides a diastolic counter pressure for providing coronary flow. During systole, the ejected fluid from the heart ventricle displaces the medium inside the annular space through the restriction to the reservoir, thereby removing energy from the fluid. The compressible medium forms a compliance. In addition, there is a preload device comprising a vertical collapsible tube forming a fluid column for preload of the atrium with a desired preload pressure without introducing air into the fluid. A pump delivers fluid to the preload device and removes fluid from the afterload device.

摘要： The invention relates to an indicator device for visually indicating a pressure of blood inside a blood vessel (8). It comprises a body (3, 10) in which a duct (14; 14') extends. The duct (14; 14') has a sealed proximal end, and the distal end portion of the body (3, 10) is adapted to be positioned inside the blood vessel (8). There is provided at the distal end of the body (3, 10), a liquid inlet opening (11) in fluid communication (6) with the duct (14; 14'). A window in the form of an at least semi-transparent section (20) is provided in the body, for enabling visual observation of blood (23) entering into the duct (14; 14') via the inlet opening (11), when the inlet opening (11) is located inside the blood vessel.

摘要： A stair traversing device comprising a payload body for transporting a payload, a step frame, and a mechanism between the step frame and the payload body to move the step frame relative to the payload body along a cyclical path. The mechanism drives a movement of one of the payload body and the step frame along a first segment of the cyclical path from a retracted configuration to an extended configuration, and drives a movement of the other one of the payload body and the step frame along a second segment of the cyclical path back into the retracted configuration. The payload body and the step frame are configured to remain fixedly in position on a stair when the other one of the payload body and the step frame is moved. The mechanism is configured to maintain the relative orientation between the payload body and the stair.

摘要： Disclosed is an apparatus, system, and method for compensating for hydrostatic pressure offset in transducer-based pressure measurements. The system may comprise: a measurement pressure transducer to measure an apparent fluid pressure at a measurement site, a reference pressure transducer to measure a hydrostatic pressure caused by a level difference between the measurement pressure transducer and the measurement site, and a controller to generate a corrected fluid pressure measurement based on the apparent fluid pressure and the hydrostatic pressure, wherein the measurement pressure transducer and the reference pressure transducer are placed at a same first level, and the measurement site and an end of a fluid-filled tube connected to the reference pressure transducer are at a same second level.

摘要： Die tragbare Sensorvorrichtung (1a) ist über einen Druckschlauch (2a) mit dem arteriellen Druckmesskatheter (3a) verbunden. Im Sensorgehäuse (12a) ist der elektronische Drucksensor (13a) untergebracht. Das analoge Sensorsignal wird über ein an die Patientenmonitorschnittstelle (14a) angeschlossenes Kabel (10a) an den Patientenmonitor (15) ausgegeben. Neben dem Kanal (16) für das analoge Sensorsignal sind weitere Kanäle zur Kommunikation zwischen Sensorvorrichtung (1a) und Patientenmonitor (15) vorgesehen. Ein bidirektionaler Kanal (17) dient dem Beschreiben und Abfragen des Speicherbausteins (18a), in welchem Patientendaten, wie Alter, Geschlecht, Körpergröße/-gewicht etc. gespeichert werden können. Über den Kennzeichnungskanal (19) kann ein Kennzeichnungssignal von dem Kennzeichnungsbauteil (20a) ausgelesen werden. Dabei handelt es sich vorteilhafterweise um eine Sensortypenkennung, welche den Patientenmonitor (15) erkennen lässt, um welche Sensorvorrichtung (1a) es sich handelt. Der Dreiwegehahn besitzt die Stellungen "M" (Messbetrieb) und "0" (Kalibriermessung), in welcher der Kontaktgeber (26) wird in Verbindung mit dem Kontakt (27) gebracht. Der vom Detektor (29) detektierte Schaltkontakt wird über ein entsprechendes Signal an den Patientenmonitor (15) übertragen, welcher so das Nullen des Sensors automatisch erkennt.

摘要： A hybrid sphygmomanometer comprises:

(a) an arm cuff with an inflatable air bladder;
(b) a pumping device for inflating the air bladder;
(c) a manually controlled air outlet valve for deflating the air bladder;
(d) an air pressure transducer operative to receive the pressure in the air bladder of the arm cuff and to produce an electrical signal representing this pressure;
(e) a manually operated switch for generating systolic and diastolic interrupt signals;
(f) a first electronic display for displaying the instantaneous pressure in the air bladder in the form of a bar graph;
(g) a second electronic display for displaying systolic and diastolic pressures; and
(h) an electrical circuit connected to the pressure transducer and to the button for controlling said first and second display.

The first display, for displaying the instantaneous pressure in the air bladder, is a simulated mercury column. The electrical circuit provides an output of digital signals, representing the systolic and diastolic pressures, for use by a programmed digital computer for storage and processing. It also provides an output of manually or digitally entered patient identification data.
