Abstract
L'invention consiste en une amélioration apportée au bras de pivotement (7) d'une lancette automatique (1). En général, une lancette automatique (1) se compose d'une enceinte (2A et 2B) ayant un bras de pivotement (7) armé par un ressort. Le bras possède un dispositif de maintien cylindrique (4) à l'extrémité de travail qui tient une aiguille (61) encaissée dans un support en plastique (60). Lorsqu'on libère le ressort (9), l'aiguille (61) perce le doigt du patient, en produisant un échantillon de sang. Pour changer l'aiguille (61), en général on retire l'aiguille usée avec les doigts et on introduit la nouvelle en la poussant. La présente invention améliore le dispositif de maintien cylindrique (4) en y ajoutant un plongeur (11) à l'intérieur. Ceci permet à l'utilisateur de sortir l'aiguille usée (61) en la poussant sans avoir besoin de saisir ni toucher l'aiguille usée. Ainsi la sécurité du personnel médical est considérablement améliorée.The invention consists of an improvement made to the pivoting arm (7) of an automatic lancet (1). In general, an automatic lancet (1) consists of an enclosure (2A and 2B) having a pivoting arm (7) armed by a spring. The arm has a cylindrical holding device (4) at the working end which holds a needle (61) received in a plastic support (60). When the spring (9) is released, the needle (61) pierces the patient's finger, producing a blood sample. To change the needle (61), generally remove the used needle with your fingers and introduce the new one by pushing it. The present invention improves the cylindrical holding device (4) by adding a plunger (11) therein. This allows the user to pull out the used needle (61) by pushing it without needing to grasp or touch the used needle. Thus the safety of medical personnel is considerably improved.
