    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.

    摘要： A pre-filled injection device having a retractable needle with a sharpened tip for penetrating the skin of a patient for administering medicinal fluids is provided. The pre-filled injection device of the present invention allows the needle to be manually retracted, thereby reducing the risk of transmission of various pathogens, most notably human immune virus (HIV), to infected personnel, due to an inadvertent needle stick. The present pre-filled injection device has a hollow housing which receives a pre-filled cartridge containing medicinal fluids. A needle retainer initially holds a needle projecting forwardly from the hollow housing. The rear end of the needle pierces the pre-filled cartridge when sufficient pressure is applied to the end of the pre-filled cartridge to advance it in the forward direction. A plunger is slidably displaceable within the housing. A latch member is operable in a latched position to prevent forward movement of the plunger. The latch member is operable in an unlatched position to permit forward movement of the plunger and retract the needle into the hollow housing.

    摘要： A safety needle-bearing medical advice (10) is provided. Specifically, a safety device for injecting medicinal fluid into a patient is provided. The device comprises a hollow housing (20), a needle assembly (40) and a plunger (30). The needle assembly (40) releasably retains a needle (43) in an extended position in which the sharpened tip of the needle is exposed for use. At the end of an injection stroke, the plunger (30) engages the needle assembly (40), such that the needle (43) is released and retracted into a cavity (38) within the plunger. The device (10) includes structure for reducing the dead-space volume, which represents the amount a fluid remaining in the device at the end of an injection stroke. In addition, preferably the device (10) includes structure for minimizing the volume of potential air bubbles trapped in the medicinal fluid prior to an injection.

    摘要： A catheter insertion device is provided for inserting an over-the-needle catheter. The device includes an insertion needle that is retractable into the housing of the device after use to prevent exposure to the contaminated needle. A needle retainer releasably retains the needle in an extended position against the rearward bias of the biasing element. The needle retainer engages the hub of the catheter so that when the catheter is removed from the insertion device, the needle retainer automatically releases the needle. The biasing element then propels the needle rearwardly into the housing of the device.
