Abstract:
A counter (32) counts the time intervals of falling instilled drops in response to a signal issue each time a falling instilled drop is detected. A memory (33) is supplied with data representing the quantities of falling instilled drop corresponding to the time intervals at which the drops fall. The data corresponding to the time intervals thereof which have been counted by the counter (32) are read out of the memory (33). The data thus read out are accumulated to determine the total quantities of the drops.
Abstract:
A method of detecting the presence in a body of a non-gaseous substrate which is volatilizable through the skin, characterised In that the method comprises introducing at the surface of the skin an enzyme selected for the substrate to be detected for a sufficient time for any of said substrate present to react with said enzyme and detecting a condition of the skin as an indication of the presence of said substrate in the body. The method is particularly suitable for determining the presence of alcohol in the body utilizing alcohol oxidase or alcohol dehydrogenase as the enzyme and employing a transcutaneous electrode arrangement for detecting skin oxygen contact.
Abstract:
An automatic blood pressure monitoring system for automatically obtaining blood pressure measurements, which includes (a) determining device for determining a measure of blood pressure of a living body; (b) detecting device for detecting a degree of saturation of oxygen in blood which flows in a peripheral part of the living body, the device generating signal representative of abnormality if the degree is found abnormal; and (c) control device being responsive to the signal supplied from the detecting device, to start the determining device to determine the measure of blood pressure. There is also disclosed an automatic blood pressure monitoring system which includes (i) determining device for determining a measure of blood pressure; (ii) detecting device for detecting a degree of saturation of oxygen in blood, the detecting device generating signal indicative of abnormality if the degree is found abnormal; and (iii) trigger device for generating first signal at intervals for periodically starting the determining device so as to determine the measure, the trigger device being responsive to the signal supplied from the detecting device, to generate second signal at intervals shorter than the intervals at which to generate the first signal, so as to periodically start the determining means for determining the measure.
Abstract:
An improved method of applying a gas permeable membrane to an electrode portion of cutaneous blood gas sensor is disclosed, wherein a cushioning disk of porous material with one-sided tackified sheet of substrate, preferably having a convex-shaped surface, is utilized when the membrane is applied to the surface of the electrode portion, to which a few drops of electrolyte solution have been supplied. According to the method of the present invention, a thin, uniform layer of electrolyte solution between the membrane and electrode portion is obtained and shortened initial stabilization period, quick response, and minimized drift of the measurement are resulted.
Abstract:
A description is given herein of a simple apparatus that does not have to be connected to any supply source and with which it is possible to utilize certain uncomplicated instruments, currently on the market, for sending in real time through the telephone lines, the twelve standard electrocardiographic leads in respect of the patient, using carrier frequency modulation in the 500 - 3000 Hz range acoustically coupled to the telephone.
Abstract:
An intravaginal and intrauterine sensor for transillumination of a blood-perfused portion of fetal tissue to measure light extinction. The sensor comprises at least one light source (21, 23) and at least one photo-sensor (20, 22) with a shielding (30). The sensor may be mounted onto a paddle-shaped probe provided with signal connections (25, 26) contained in an insulated cable (27) leading to a measurement device. Alternatively, the sensor may include an opaque suction cup or other attaching apparatus for disposition on a protruding portion of the fetus. Most preferably, the sensor includes a housing.
Abstract:
A device for measuring intrauterine pressure during pregnancy and during labor prior to the rupture of the amniotic membrane comprises an elongate catheter (2) having a uterine end (4) and an instrumentation end (6). The end (4) of the device is introduced into the uterus. The catheter has an inflatable pressure transmitting membrane (8) and another inflatable membrane (20) for anchoring the end (4) of the catheter in position within the uterus. Flow control means (10, 28, 32) are provided for controlling the fluid used to inflate the membrane (8, 20).
Abstract:
A photoelectric brain scanner for experimental animals generally comprises a flexible cord assembly (3) having a pair of optical conductions (301, 302) in-and-out coated with a light insulator and also having a probe (33) for penetrating into brain tissues at one end and twin inletloutlet plugs (31) at the other end, means for driving the probe in the longitudinal direction, and a photoelectric processor which provides light to be transmitted into the brain tissues to present the scanning results, e.g. as a chart.
Abstract:
An apparatus for the execution of a gastro-esophageal pHmetric test, particularly for pH monitoring throughout 24 hours, avoiding patient hospitalization and allowing the latter to continue normal life habits. It comprises a pHmetric electrode opportunely positioned in the patient's esophagus and/or stomach and a portable recording unit of very small dimensions, that is given to the patient to be tested, connected to said electrode. The recording unit comprises voltage-frequency converter that receives a DC signal from the electrode and produces a frequency signal proportional to the amplitude of the input signal; it also comprises a timer connected between said converter and a recording device, for enabling the frequency signal to be transferred to said device and simultaneously for actuating the same in correspondence with prefixed sampling intervals. The apparatus comprises finally a unit for analysing said frequency signal and visualising the test results.
