摘要:
A simple and versatile system for the safe transfer and collection of body fluids, such as blood, wherein an enlarged generally cup-shaped guide port (10) receives therewithin the transfer needle (16) which is recessed rearwardly from the open end of the guide port (10) whereby the transfer needle assembly (12) may be manipulated without likelihood of needlestick injury to the health care worker. Larger guide ports (10) have apertured snap on caps (22) to facilitate and guide a transfer receiver into contact with the needle (16) as well as to isolate further the worker's hand from the contaminated needle. A plurarility of sizes of guide ports (10) and caps (22) are provided for varying fluid receivers, with all having common interlocking means for the transfer needle assembly (12).
摘要:
L'invention concerne un dispositif pour la préparation d'une solution médicinale à partir de deux composants dont l'un est à l'état de poudre, de lyophilisat ou de liquide et dont l'autre est un diluant ou un solvant liquide. Ces composants sont respectivement stockés dans un conteneur distal (11) fermé et un conteneur proximal (13), qui présentent chacun une ouverture obturée par un obturateur-piston-vanne, mobile axialement. Ces deux obturateurs-pistons-vannes (19, 24) sont reliés par une tige de transfert (15) agencée pour assurer une liaison de couplage rigide, étanche et stérile entre les deux obturateurs-pistons-vannes (19, 24) lorsque le dispositif (10) se trouve dans une position de stockage, et pour définir un canal de communication étanche et stérile entre les deux conteneurs (11, 13) lorsque le dispositif se trouve dans une position d'utilisation. Les obturateurs-pistons-vannes (19, 24) ont une zone centrale pourvue d'une fente (31, 33) fortement comprimée et fermée de façon étanche lorsque le dispositif est en position de stockage, et ouverte lorsqu'une extrémité de la tige de transfert (15) y est introduite, le dispositif étant dans ladite position d'utilisation.
摘要:
On décrit un raccord de sécurité pouvant être raccordé à l'orifice de branchement d'un conduit d'écoulement de liquide. Le raccord comporte un corps tubulaire (202) pourvu d'une ouverture (218) à son extrémité distale afin de recevoir un orifice de branchement et d'un canal (204) dans la paroi du corps tubulaire contigu à l'extrémité distale. Le canal est conçu pour recevoir le conduit d'écoulement du liquide lorsque l'orifice de branchement est engagé dans le corps tubulaire. Le raccord comprend également un collier rotatif de blocage (212) placé sur l'extrémité distale du corps tubulaire. Le collier est rotatif à partir d'une première position dans laquelle le canal est conçu pour recevoir le conduit d'écoulement du liquide lorsque l'orifice de branchement est engagé dans le corps tubulaire, et une seconde position dans laquelle le collier empêche l'orifice de branchement de sortir du corps tubulaire.
摘要:
A sealed fluid transfer device comprised of tubing, a proximal fitting, and a distal needle assembly is provided. The needle assembly includes a needle hub secured to a needle cannula. A cantilevered actuator arm extends outwardly from the needle hub having an actuator button at its free end. The needle assembly is disposed in a barrel and can move from a distal position, where the needle is exposed, to a proximal position, where the needle is shielded. The barrel includes a septum which seals the barrel. A spring is disposed in the barrel for propelling the needle assembly to the proximal position. The barrel includes an aperture that receives the actuator button for locking the spring in a compressed condition. Depression of the actuator button enables the spring to propel the needle assembly into its proximal position. A safety mechanism prevents inadvertent depression of the actuator button.
摘要:
A filling system for syringes utilizing short needles to be filled from a vial having a thick septum is described. The system may be useful in any situation where the septum or vial stopper of a medication container is thicker than the usable length of the needle on the delivery device. Preferably, the syringe is filled just prior to use. The short needle includes an optional limiter which only permits a certain predetermined length of the needle cannula to protrude beyond the limiter a distance which limits penetration of the needle tip into both the skin and a vial stopper. The system and adapter may be useful for needles having a protrusion distance from approximately 0.5 mm to 3 mm, or any needle with a protrusion length shorter that the thickness of a septum to be accessed. Furthermore, a device is provided with shielding capabilities to shield the needle of the device.

A single-use syringe (10) includes a needle (18), barrel (16), plunger assembly (20) and shield (12). The barrel (16) bears a locking member (26) which encircles the front end of the barrel (16) and is carried forward by the barrel (16) to a position where it engages the shield (12) and is retained by the shield (12) such that the locking member (26) is separated from the barrel (16) as the barrel (16) is withdrawn rearwardly after use. The locking member (26) is resilient and, after it is removed from the barrel (16), assumes a configuration which prevents subsequent forward movement of the barrel (16) within the shield (12). The barrel includes a frangible seal (30) which is broken by rearward movement of needle mount (32). The shield (12) includes a shield extender (14) for controlling the depth of penetration of the needle. The syringe can also be used to inject medicament into a IV bag via a male port as shown in Fig. 7.
摘要:
The above-discussed and other drawbacks and deficiencies of prior art are overcome or alleviated by the closed system access device (100) of the present invention. The closed system access device (100) provides a tool for managing fluid transaction that ensures the sterility of a needle (122), prevents exposure to toxic or hazardous medicines, and protects against needle sticks by completely encasing the needle (122) in a housing (102). The device allows for a protected needle withdrawal of blood, injection of medicine and transfer of fluids by use of an unexposed, internal needle which inhibits contamination and prevents contact with the transferred blood and/or medicine.
摘要:
A device for preparing a medicinal solution from two components of which one is powdered, freeze-dried or liquid while the other is a diluent or liquid solvent. The components are held in a sealed distal container (11) and a proximal container (13) respectively, and each container has an opening sealed by an axially slidable valve plug. The slidable valve plugs (19, 24) are interconnected by a transfer rod (15) providing a rigid, sealed and sterile coupling therebetween when the device (10) is in a storage position, and defining a sealed and sterile communicating channel between the two containers (11, 13) when the device is in an operative position. Said valve plugs (19, 24) have a central region provided with a slot (31, 33) which is tightly closed and sealed when the device is in the storage position, and open when one end of the transfer rod (15) is inserted therein with the device in the operative position.
