Blood draw device with retractable needle

The Invention comprises a body, an actuator pivotally connected to the body, and a retractable needle adapted to provide fluid communication between a patient and a fluid collection tube, typically a blood collection tube, attachable to the device. A significant feature of the subject device is a retraction cavity disposed inside the actuator that is manually positionable to receive a portion of the needle retraction assembly following removal of the blood collection tube. Retraction is initiated by depressing the forwardly extending end of the actuator relative to the body, thereby causing a retainer clip to release the needle holder, after which the needle holder and a part of the needle are propelled into the retraction cavity by expansion of a compressed spring. The needle is thereby withdrawn from the patient and into the housing, reducing the likelihood of accidental needle sticks and preventing reuse of the device.

Bazı düzenlemeler ayrıca, kateterin bir kan damarı içine sokulmasına yardımcı olan ve cihazın bertaraf edilmeye hazır olduğu zaman kullanıcıyı kazara bir iğne batmasından koruyan bir geri çekme özelliğine sahip bir iğneyi içerir. Yine diğer düzenlemeler, kullanıcının kanının bir toplama cihazına alınması için kullanılan ikinci bir iğnenin yanlışlıkla takılmasını engelleyen koruyucu bir kapağı da içermektedir. They are an apparatus and methods for a single, hand-held device that allows both a catheter to be inserted and a fluid to be collected. Some embodiments also include a needle having a withdrawal feature that helps insert the catheter into a blood vessel and protects the user from accidental needle insertion when the device is ready to be disposed of.

Blood draw device with retractable needle

The Invention comprises a body, an actuator pivotally connected to the body, and a retractable needle adapted to provide fluid communication between a patient and a fluid collection tube, typically a blood collection tube, attachable to the device. A significant feature of the subject device is a retraction cavity disposed inside the actuator that is manually positionable to receive a portion of the needle retraction assembly following removal of the blood collection tube. Retraction is initiated by depressing the forwardly extending end of the actuator relative to the body, thereby causing a retainer clip to release the needle holder, after which the needle holder and a part of the needle are propelled into the retraction cavity by expansion of a compressed spring. The needle is thereby withdrawn from the patient and into the housing, reducing the likelihood of accidental needle sticks and preventing reuse of the device.

Blood collection device with needle container means

A safety blood collection device including holder housing adapted to maintain a needle cannula with a puncture tip extending from a forward end thereof and to receive a sample collection tube through a rearward end thereof. A retainer coacts with the holder housing to maintain the needle in a first position with the puncture tip of the needle extending from the forward end of the holder housing. The retainer is adapted for activation so as to release the needle from this first position, thereby permitting the needle to move based on the force of gravity and the weight of the needle to a second position in which the puncture tip of the needle cannula is contained within the interior chamber of the holder housing. As such, upright placement of the holder housing upon activation of the retainer will permit the needle to drop within the holder housing, thereby containing the needle cannula therein as a self-contained assembly.
