  • U.S. Patent No. 5,700,250 entitled “Catheter-Advancement Actuated Needle Retracted System” discloses a device including a generally hollow barrel that houses a needle hub having a flash chamber and affixed to a needle. In a pre-use (idle) position the needle extends through a catheter unit and along with a catheter tube protrudes distally of the hollow barrel. A spring is disposed in the barrel to urge the needle hub towards the barrel proximal end.
  • There is a latch mechanism including an elongated stem within the hollow barrel and passively actuated during the advance of the catheter tube into patient's blood vessel, allowing retracting the needle unit by the spring into a protection position in the hollow barrel after the catheter emplacement. The passive actuation of the needle hub retraction substantially improves the device operation convenience and heightens device safety. There is also a means for cushioning the needle hub when it is retracted against the barrel proximal end.
  • a disadvantage of this device is its considerable length in the pre-use position approximately equal to the sum of the barrel and catheter unit lengths.

  • Another disadvantage includes difficulty controlling the device with one hand. This difficulty is caused by the following factors: the relative complex device design with the disposition of the elongated stem within the hollow barrel; the excessively elongated needle with the above mentioned spring location; and a substantial time delay in blood entering the flash chamber.

Abstract

L'invention concerne un dispositif d'introduction de cathéter de sécurité (20) de conception compacte, ayant une longueur inférieure dans les états de transport et de stockage, qui est également pourvu d'un mécanisme de rétraction actionné de manière passive pour une rétraction d'aiguille dans une position protégée après utilisation. Le cathéter de sécurité permet une commande pratique du dispositif d'introduction de cathéter par un utilisateur associé utilisant une main. Le cathéter de sécurité permet également une fixation automatique des éléments constitutifs du dispositif d'introduction dans des positions de pénétration et de protection sans aucune action spéciale de l'opérateur. Le cathéter de sécurité comprend une chambre flash améliorée (30) pour une visualisation au moment où le sang d'un patient associé entre dans la chambre flash. Le cathéter de sécurité comprend en outre un recouvrement de sécurité (60) d'un orifice d'injection (55) qui élimine sensiblement une infection de l'orifice d'injection par un contact accidentel avec le personnel.
