The present disclosure relates to an electrical connector for providing signal isolation between various components of a physiological monitoring system. In an embodiment, the electrical connector is placed between a sensor and associated monitoring system and includes a physical barrier and inductive components.

A disposable cover for an elongated probe of a portable thermometry apparatus includes an open proximal end and a distal tip sized to fit over at least an axial portion of the elongated probe. The cover includes a transitional wall thickness at its proximal end for fitting over a holding barb of said probe, the transitional wall thickness varying between a first wall thickness adjacent the proximal end and a second wall thickness that is substantially thinner than the first wall thickness at a distal axial distance relative to the proximal end. The second wall thickness defines a weakened wall portion which is ruptured when the cover has been ejected from said holding barb by an ejection mechanism of the thermometry apparatus. The cover can also include a thinned walled portion over at least a portion of the distal tip and can also include a feature that permits the user to detect when a cover has been attached to a probe.

A method of monitoring the progress of labor in a mother during childbirth, by attaching a position sensor to a predetermined point on the mother's pelvic bones; monitoring the location of the position sensor in three- dimensional space relative to a reference; and monitoring the location of the fetal presenting part with respect to the predetermined point on the mother's pelvic bones. The location of the fetal presenting part may be indicated by a similar position sensor, or by imaging. Other conditions, such as effacement, cervical dilatation, and cervical position may also be monitored in a similar manner.

The present invention relates to a closed capsule designed to be extracted under pressure in an extraction device, containing a substance 43 for the preparation of a beverage, comprising a closed system 44, 45 containing the said substance and a means 46, 48 inside the said system allowing the said capsule to be opened at the time of its use and allowing the said beverage to flow out without contact with its extraction system.

The invention provides a packaging for a medical article e.g. for a urinary catheter. The medical article is stored in a compartment and can be accessed by detaching a first element from a second element thereby forming an opening into the compartment. The first element comprises a suction cup or another fastening element by which the packaging is attachable to a surface. Due to the structure of the packaging, it can be supported in an orientation in which the opening is remote from the surface, and risk of contamination of the medical article can therefore be reduced during removal of the article from the packaging.

A blood set comprises an arterial line having a patient end provided with a multiport connector (14) having first port (15) connected to a blood transport tube (13), a second port (16) bearing a male luer connector for connecting to a vascular access device (17), and a third port (18) connected to a service tube (20) terminating with female luer connector (23) for connection with a priming liquid supply line. The blood set operates rapidly and with a small risk of contamination for the patient.

The invention discloses a selenium-enriched rice which is produced by processing selenium-enriched paddy rice, the selenium-enriched paddy rice is obtained by applying a nutritional agent for the selenium-enriched paddy rice in the soil of a paddy field for cultivation after land preparation and before irrigation, and the weight composition of the nutritional agent for the selenium-enriched paddy rice is as follows: nano-selenium plant nutritional agent: nitrogen-phosphorus-potassium compound fertilizer is equal to 0.1-1: 1, wherein the weight concentration of selenium in the nutritional agent for the selenium-enriched paddy rice is 2000-10000mg / kg. The selenium content of the selenium-enriched rice is 0.04-0.300mg / kg, the proportion of organic selenium is more than 80%, and the form is safer. The production method of the selenium-enriched rice is simpler, the using amount of the nutritional agent for the selenium-enriched paddy rice is small, and the environmental pollution is small.

A reactor for plating a metal onto a surface of a workpiece is set forth. The reactor comprises a reactor bowl including an electroplating solution disposed therein and an anode disposed in the reactor bowl in contact with the electroplating solution. A contact assembly is spaced from the anode within the reactor bowl. The contact assembly includes a plurality of contacts disposed to contact a peripheral edge of the surface of the workpiece to provide electroplating power to the surface of the workpiece. The contacts execute a wiping action against the surface of the workpiece as the workpiece is brought into engagement therewith The contact assembly also including a barrier disposed interior of the plurality of contacts. The barrier includes a member disposed to engage the surface of the workpiece to assist in isolating the plurality of contacts from the electroplating solution. In one embodiment, the plurality of contacts are in the form of discrete flexures while in another embodiment the plurality of contacts are in the form of a Belleville ring contact. A flow path may be provided in the contact assembly for providing a purging gas to the plurality of contacts and the peripheral edge of the workpiece. The purging gas may be used to assist in the formation of the barrier of the contact assembly. A combined electroplating / electroless plating tool and method are also set forth.

The present invention discloses an adhesive tape to secure an intravascular catheter to the skin of a patient at an intravascular site comprising: (a) a strip of tape having adhesive on all of one side except for portions at the ends, the strip of tape having a length of about 15 to about 300 mm and width of about 4 to about 30 mm; (b) two removable covers affixed near the ends of the adhesive side of the strip, wherein the removable covers are separated from each other by a centrally located portion of the strip of tape; and (c) a third removable cover affixed to the central portion of the adhesive side of the strip of tape. The subject invention further reveals a sterile intravascular starter kit, said kit being comprised of the adhesive tape for an intravascular catheter, a tourniquet, a gauze pad, an antiseptic skin preparation device, optionally a towel, and a clear occlusive dressing.

A process for cultivating photosynthetic microbes comprising Closed Systems for continuous cultivation and Open Systems for batch cultivation, in which (a) the Closed System Area occupies no more than 20% of the Total Land Area of the cultivation facility; (b) batch cultures in the Open Systems are initiated with an inoculum from the Closed Systems containing a cell biomass of no less than 5% of the carrying capacity of said Open System; (c) the doubling rate of said photosynthetic microbe is no less than once every 16 hours; and (d) the residence time of the batch culture in said Open System is no more than a period of 5 days.
