The invention relates to a device for treating an individual suffering from cardiac or circulatory arrest or from a stroke, comprising a blood withdrawal device (BE) that is applied to the individual (P), an analysis unit (BA) which is directly or indirectly connected to the blood withdrawal device for detecting a blood analysis result (BAE) providing at least one characteristic of the blood, directly or indirectly connected to a blood return device (BR) that is applied to the individual (P) and is designed to deliver a substance to the individual via the return device (BR).

A pellet having a convex shaped front includes a plurality of radially disposed surface slots. The concave shaped rear portion has a matching number of surface ribs that can be frictionally attached to the convex portion's slots. The pellet is constructed of a combination of medical compounds along with appropriate binders and other compounds that are pressed together under high pressure to produce a rigid mass capable of being propelled at high speeds and to pierce the skin of an animal or person where the compounds can be dissolved when contacting the internal liquid portion of the animal or person. The pellet can be loaded and propelled by a standard air rifle, gun, or pistol.

Certain substances (e.g., large molecules) that ordinarily cannot traverse the blood brain barrier can be introduced into the brain by applying an alternating electric field to the brain for a period of time, wherein the frequency of the alternating electric field is selected so that application of the alternating electric field increases permeability of the blood brain barrier. In some embodiments, the frequency of the alternating electric field is less than 190 kHz (e.g., 100 kHz). Once the permeability of the blood brain barrier has been increased, the substance is able to cross the blood brain barrier.

A rigid hollow tubular adapter releasably attached at a longitudinal nozzle end to a flexible tube during equine nasogastric intubation comprising an annular sleeve having a stationary tubular member and a slidable tubular member. The slidable tubular member is delimited at its ends by the stationary tubular member and a detent member disposed between an equine reflux drainage hole and a longitudinal mouthpiece end. Operator's puffs of airflow through a mouthpiece urges the slidable member to slide toward the detent member closing the equine drainage hole to enable passage of medication into the equine stomach. Equine reflux urges the slidable tubular member to slide toward the stationary tubular member opening the reflux drainage hole to divert equine backflow downwardly through the equine backflow drainage hole preventing passage of equine reflux into the operator's mouth.

The present invention is directed to a needle sensor assembly and a method of using same. The needle sensor assembly includes a needle sensor housed within the needle sensor assembly. The needle sensor assembly is configured to be attached to an injection device. When the needle sensor assembly is attached to the injection device, the needle sensor is configured to detect if a needle positioned for use in the injection device is misaligned, absent, or broken.

A device for the uninterrupted administration of fluid to an animal body during a draw of bodily fluid, e.g., blood, is disclosed. A first fluid channel is configured to selectively transport IV fluid to an animal body and to draw a bodily fluid from the body. A sealing member for sealing a bodily fluid draw port defines a concave surface on a first end. The sealing member concave surface forms an interior surface portion of the first fluid channel. A connection member is configured to connect to a catheter to the first fluid channel and defines a concave distal end. A second fluid channel continuously provides IV fluid to a lumen coaxially located within the catheter. The concave surface and the concave distal end are shaped to create fluid flow patterns that quickly and completely remove residual bodily fluid remaining after a draw of bodily fluid is completed.

The present subject matter relates to semi-automatically controllable syringe (100A-100E, 200, 300, 400, 500, 600, 710, 800A) comprising barrel (102A, 102B, 202, 302, 402), plunger (104, 204, 304, 404, 508, 606), actuating member (116, 124, 206, 306, 406, 510, 608), biasing member (110, 210, 310, 410, 506), and movement control mechanism (118, 120, 218, 314, 418, 516, 618). Actuating member (116, 206, 306, 406, 510, 608) is to move plunger (104, 204, 304, 404, 508, 606). Biasing member (110, 210, 310, 410, 506) biases upon plunger movement in first direction and applies restoring force on plunger (104, 204, 304, 404, 508, 606) towards second direction. Movement control mechanism (118, 120, 218, 314, 418, 516, 618) includes pin-receiving members (118B, 120B, 218B, 314B, 418B, 516B, 618B) and pin (118A, 120A, 218A, 314A, 418A, 516A, 618A) to provide variable limit for plunger movement.

Some embodiments of an inhalation exposure system can deliver a gas, such as an aerosol, through a manifold to a set of exposure chambers in a controlled manner so as to achieve improved consistency for all of the test subjects.

Some embodiments of an inhalation exposure system can deliver a gas, such as an aerosol, to a set of exposure chambers in a controlled manner and can monitor one or more characteristics of the gas at a variety of aerosol delivery rates for output to a user interface. In some implementations, the improved user interface of the system may alert the user to a fitting range of aerosol delivery rates.

Systems and methods suitable for extracorporeal lung support are provided that expose blood, across a semipermeable membrane, to a dialysis liquid. The dialysis liquid features a buffering agent and has a high buffering capacity for H.sup.+ ions. Carbon dioxide, bicarbonate and hydrogen cations are transported across a semipermeable membrane into the dialysis liquid. The dialysis fluid may be recycled and repeatedly used, and its pH may be adjusted, and other fluids added to it. Certain substances may be removed from the blood, and the amount of these substances removed from the blood may be substantially automatically or substantially continuously monitored or quantified. The systems and methods are suitable for treating or preventing respiratory acidosis, metabolic acidosis, and diseases featuring lung malfunction, kidney malfunction, or liver malfunction.
