Medical device for inserting a guide wire having a retractable needle |
摘要 |
A needle-bearing medical device is provided for inserting a guide wire. After use the needle is shielded to render the contaminated needle safe to prevent inadvertent needle sticks. The device includes a housing and a needle having a sharpened tip. A biasing element biases the needle toward a position in which the sharpened tip is shielded. A connector is provided for attaching a fluid collection device to the guide wire insertion device, if desired. A guide is configured for guiding the guide wire through the port and into the needle. A method is also provided for using the medical device, in which the needle is inserted vascularly into a patient. A fluid collection device is attached to the connector of the device and blood is drawn into the fluid collection device to ensure that the needle is properly positioned within a vein or artery of the patient. A guide wire is then inserted into the patient through the device and the needle is retracted to shield the needle. In one embodiment, the device includes a second port through which the guide wire is inserted while the fluid collection device is attached to the insertion device. The device may also include a shield configured for vascular insertion, which shields the needle after the needle is retracted.
