摘要： A single use retractable medical device dispenses fluids from a separable carpule. A retraction mechanism having a spring loaded needle holder with a double ended needle is mounted in the front of a housing by means of a push ring (separable member) slidingly mounted on a widened portion of the needle holder. An outer edge of the push ring grips or is restrained by the inner wall surface of the housing to hold the needle holder in place. A carpule positioned through an opening in back of the housing is operated by a plunger which drives a separable two-part piston to unload medicine from the carpule through the needle. At the end of an injection, the plunger is depressed further. The carpule moves forward to remove the push ring thereby freeing the needle holder for retraction into the carpule through the front opening of the carpule. As the needle is retracted into the housing from one end, the edge of the thumb cap of the plunger disappears into an opening at the opposite end of the housing. The back of the housing may have the traditional thumb ring or it may have a “disappearing” thumb cap which is received into a widened opening in the back of the housing to thwart removal.

摘要： A device having a housing; a cannula projecting forwardly from the housing; a connector useful for attaching the device to a fluid source or receptacle; a fluid flow path establishing fluid communication between the cannula and the connector; a retraction mechanism biasing the cannula away from its projecting position; and an actuator supported by the housing and configured to modify the fluid flow path so as to terminate fluid flow through the device, seal off the fluid flow path, and release the retraction mechanism to retract the cannula into the housing. The subject device is particularly preferred for use in the medical field, for example, as part of an infusion set or as a collection device for blood, or other fluids or flowable matter.
