摘要:
A patient care system (90) comprising an interface unit (100), an infusion pump unit (150a), and a capnography unit (150b) is disclosed. The infusion pump unit (150a) is used to administer medical fluids to a patient, including the administration of anesthetics, analgesics, or sedatives. The capnography unit (150b) provides monitoring of the patient's expired air, in particular, the end tidal CO 2 levels in the expired air and the respiration rate. When the capnography unit (150b) indicates to the interface unit that the end tidal CO 2 level and/or pulse rate has reached a point outside a specified range, the interface unit (100) initiates visual and audio alarms and controls the infusion pump unit (150a) by modifying the flow or by shutting off the pump unit. In patient controlled analgesia applications, the interface unit (100) may block patient-controlled bolus doses of the analgesic until reset by a qualified medical professional or until the measured capnography values return to a normal range. The interface unit (100) also contains communication ports, which the interface unit can use to send signals to external devices, such as to alert medical personnel.

摘要:
A male luer connector device that attaches to any standard female luer valve to open a flow channel between the two luers. The male luer is comprised of a tubular housing element, a resilient member contained within the housing and extending within an inner tubular portion defined in the housing, a resilient member that extends within the inner tubular portion of the housing, and a valve member attached to the resilient member that seals the tubular portion. When the male luer is engaged with any standard female luer, a female luer connector device drives the resilient member of the male luer into a compressed position to open the forward end of the male luer and permit liquid flow between the luers.
摘要:
A self-sealing male Luer connector for connection with a female Luer conector. The male Luer connector includes a housing having a distally-projecting tubular male body and a surrounding cuff interconnected by a proximal wall in which is formed at least one activation opening. A valve plug is slidably installed within the housing and formed with a distal end configured to sealingly engage the distal end of the male body's interior flow passage and with at least one activation arm at its proximal end configured to extend through the activation opening into the cavity formed between the body and the cuff. An elastomeric device is sealingly configured within the activation opening about the activation arm to secure the valve plug in position and bias it distally. The proximal end of the male Luer connector may be configured as a conventional female connector, a blood collection device, or other such device.
摘要:
A needle-free medical connector (20) includes a housing (22) with a first port (28) and a second port (32). The connector also includes a piston element (38) defining a fluid passageway between the first and second ports. The piston element is movable between flow and non-flow positions. The piston element has an expandable section (56) having a variable inner width and volume that forms a part of the flow path through the connector. As the piston is compressed to the flow position, the expandable section is expanded in width by movement over a flow post (40) thereby maintaining or increasing the volume of the fluid passageway through the connector. The expandable section has a configuration permitting the continuous flow of fluid through its entirety.
摘要:
A vial adapter (21) having a needle-free valve (37), a sharpened cannula (33) used to perforate a vial's rubber stopper, and a circular array of claws (28) of different lengths to engage vial closures of different diameters. The array of claws (28) includes a first set of claws (29) each having a first length extending inwardly from the periphery (27, 67) of the housing (23) of the adapter (21) and a second set of claws (31) alternating with the first set of claws (29) and each having a longer length. The second set of claws (31) are mounted so that they deflect and plastically deform out of the way in the case where the adapter is engaged with a vial that exceeds a predetermined size. The housing (23) includes a shroud (27) that is at least as long as the sharpened cannula (33) to protect medical personnel who use the adapter from inadvertent punctures. The needle-free valve (37) includes a resiliently deformable piston element (45) with a naturally open bore (47) . The interior of the piston provides a fluid flow path through the adapter (21). In one embodiment, the first set of claws (29) of the adapter (21) may be used with a vial closure of at approximately 20 mm in diameter and the second set of claws (31) may be used with a vial closure of approximately 13 to 17 mm in diameter.
