摘要： A medical injector is provided herein which includes a body; a slidable button at least partially disposed in the body; a displaceable plunger disposed in the body; a spring disposed to advance the plunger; and, a releasable retainer for retaining the plunger in a first state against force of the spring. Upon a predetermined extent of sliding movement of the button, the button engages the releasable retainer so as to cause the releasable retainer to release the plunger thus allowing the spring to advance the plunger. Advantageously, the subject invention provides a medical injector having an automated plunger drive which is triggered upon button activation, thereby minimizing premature or failed activations.

摘要： A medical injector is provided herein which includes first and second body portions each having a longitudinal axis and configured to couple at a coupling. The first and second body portions are complementarily formed so as to be movable about the coupling. The medical injector also includes an axially-displaceable plunger; biasing element for advancing the plunger a predetermined distance; and, a releasable retainer for releasably retaining the plunger in a first state against the force of the biasing element. In an initial state, the axes of the first and second body portions are not aligned and the plunger is in the first state. In a coupled state, the axes of the first and second body portions are axially aligned, and the releasable retainer releases the plunger, thereby allowing the biasing element to advance the plunger the predetermined distance. Advantageously, the subject invention provides a medical injector having an automated plunger drive which is triggered upon assembly of the pen injector, thereby minimizing premature or failed activations.

摘要： Mechanisms are provided for automatically removing tips from a pipette nozzle and/or for detecting the type of tip mounted to the nozzle. For detipping, mechanical energy is stored when the tip is mounted to the nozzle and is released when the tip is to be removed to facilitate removal thereof. A mechanism is preferably provided which limits the force with which the tip is mounted to the nozzle and an overforce mechanism may be provided to facilitate removal of a stuck tip. For detecting tip type, each tip type has a different base configuration which results in a different relative displacement between the nozzle and a surrounding component as a result of the tip contacting both during tip mounting, the difference in relative displacement being detected to identify tip type.

摘要： A medical injector is provided herein having a body and a reservoir disposed in the body, the reservoir including at least first and second mixable components. At least one stopper is associated with the reservoir where distal advancement of the stopper over a predetermined distance causes mixing of the mixable components. A plunger is disposed in the body, along with a knob stem and a knob fixed to the knob stem so as to be rotatable therewith. A sleeve is telescopingly disposed over the knob stem, wherein the knob stem and the sleeve have cooperating elements formed thereon which selectively permit rotation of the knob stem to be transmitted to the sleeve so that the knob stem and the sleeve may rotate together. A spring is also provided for urging the sleeve distally. A releasable retainer releasably retains the sleeve against force of the spring. Rotation of the knob releases the sleeve and allows the spring to displace the sleeve distally. Distal movement of the sleeve causes distal movement of the plunger which causes distal movement of the stopper thus causing mixing of the mixable components. Advantageously, with the subject invention, a medical injector may be provided where autoreconstitution can be achieved by the turning of a knob.

摘要： A drain device for the continuous removal of condensate from an operational patient breathing circuit comprises a body having a first opening adapted for connection to a patient breathing apparatus. A second opening in the body is adapted for connection to a patient breathing device. There is a passageway in the body which provides fluid communication between these openings, with a third opening through the body communicating with the passageway. A liquid-pervious, gas-impervious material covers the third opening so that condensate can continuously drain through the third opening while the breathing circuit is in operation.

摘要： A medical injector is provided herein having a body with a displaceable plunger. The plunger includes a plurality of spaced-apart ratchet teeth disposed along the length thereof. At least one indexer is provided formed to engage the plunger, wherein the indexer is configured to allow the plunger to displace distally towards a distal end of the body but not proximally towards a proximal end of the body. The medical injector also includes an actuator having an engagement portion formed to engage one or more of the ratchet teeth. The actuator is displaceable to a ready state, the engagement portion being displaced proximally relative to the plunger with the actuator being displaced to the ready state. The indexer prevents proximal movement of the plunger thereby allowing the engagement portion to by-pass one or more of the ratchet teeth with the actuator being displaced to the ready state. In addition, the actuator is displaceable from the ready state to cause actuation of the medical injector. The displacement from the ready state causes distal displacement of the engagement portion with the engagement portion engaging one or more of the ratchet teeth and causing distal displacement of the plunger with the engagement portion. Advantageously, the subject invention provides a plunger for a medical injector which may be controllably advanced with a minimum number of cooperating parts.
