摘要:
A portable gas fractionalization apparatus that provides oxygen rich air to patients is provided. The apparatus is compact, lightweight, and low-noise. The components are assembled in a housing that is divided into two compartments. One compartment is maintained at a lower temperature than the other compartment. The lower temperature compartment is configured for mounting components that can be damaged by heat. The higher temperature compartment is configured for mounting heat generating components. An air stream is directed to flow from an ambient air inlet to an air outlet constantly so that there is always a fresh source of cooling air. The apparatus utilizes a PSA unit to produce an oxygen enriched product. The PSA unit incorporates a novel single ended column design in which all flow paths and valves can be co-located on a single integrated manifold. The apparatus also can be used in conjunction with a satellite conserver and a mobility cart.

Disclosed is a method and apparatus for accomplishing a noninvasive screen for breast disease markers, including breast cancer markers and cytologically abnormal cells. Intraductal fluid is noninvasively aspirated using compression, heating and suction cycles. The removed sample is thereafter assayed for the presence of cytologically abnormal cells and/or one or more breast disease markers. In addition to the diagnostic applications of the disclosed method and apparatus, a therapeutic application is also contemplated wherein intraductal fluids are noninvasively aspirated using compression, heating and suction cycles to remove toxic buildups within the fluid.

Disclosed is a disposable patient interface for an intraductal fluid aspiration system. The interface has a flexible tubular distal member for contacting the patient, and a proximal support portion forming a vacuum chamber therein. The support portion has a vacuum aperture for communication with a source of vacuum, and a retention structure for releasably mounting within a hand piece of an intraductal fluid aspiration system. The flexible member preferably has a low modulus of elasticity and a high tear strength, such that it can be stretched to fit over a rigid support without rupture.

A retractable safety syringe may comprise a needle, needle holder, syringe body, and a plunger. A proximal portion of the body and a piston of the plunger may define a variable vacuum compartment. A through hole pneumatically connecting ambient air and the variable vacuum compartment may be formed through a thumb platform and rigid shaft of the plunger for allowing air to escape out of the variable vacuum compartment when a piston of the plunger is traversed toward the retracted position and allow air to be introduced into the variable vacuum compartment when the piston is traversed toward the engaged position. A retraction force may be created by the variable vacuum compartment by covering an entrance of the through hole and traversing the piston to the engaged position. At the engaged position, the piston may engage the needle holder and the retraction force may retract the piston, needle holder and needle into the syringe body to prevent accidental needle pricking and needle reuse.

摘要:
A retractable needle safety syringe is provided having a braking mechanism. The braking mechanism may be disposed at a proximal portion of a syringe body of the syringe. The braking mechanism may comprise a brake member which is traversable between a braking position and a released position. At the braking position, the brake member frictionally engages an outer surface of the shaft of a plunger of the syringe. The frictional engagement counterbalances a retraction force that urges a piston of the syringe toward a retracted position. When the brake member is traversed to the released position, the brake member does not press against the outer surface of the shaft. As such, the retraction force may traverse the piston toward the retracted position and traverse a needle and needle holder into the body of the syringe.
摘要:
A retractable safety syringe is provided herein wherein an external vacuum compartment produces a retraction force which urges a piston of a plunger toward a retracted position. The retractable safety syringe may have a needle holder which is removably engageable to a distal portion of a syringe body. When the piston is traversed toward the engaged position, the external variable vacuum compartment produces a retraction force. When the piston is traversed to an engaged position, the piston engages the needle holder and disengages the needle holder from the syringe body. The medical professional may release a thumb pressure on a thumb platform of a plunger. At this point, the retraction force of the external variable vacuum compartment may traverse the piston along with the needle holder and needle toward the retracted position and into the syringe body. An internal variable vacuum compartment may also create a retraction force to assist retraction of the needle holder and needle into the syringe body.
