    • The present invention relates to medical devices and particularly to a medication delivery device for self-injection of a medication, or for healthcare professionals to administer a medication. In one embodiment, a medication delivery device utilizes a source of gas pressure to deploy a needle, deliver a desired amount of medication through the needle, and retract the needle for disposal. Fluid flow paths from the source of gas pressure communicate the gas pressure to the needle and to the medication in order to accomplish these steps. In one embodiment, a valve is positioned to open and close the flow of the pressurized gas to the needle and the flow of the medication to the needle, so that the valve can be operated to deploy the needle and deliver the medication through the needle when the user is ready for the injection. The valve can also be operated to retract the needle when the dose is complete.
    • 本发明涉及医疗装置,特别涉及一种用于药物自身注射的药物输送装置,或用于医疗保健专业人员来施用药物。 在一个实施例中,药物输送装置利用气体压力源来展开针头,通过针头递送所需量的药物,并且将针头收回以便处置。 来自气体压力源的流体流动路径将气体压力传递到针头和药物,以便完成这些步骤。 在一个实施例中,阀被定位成打开和关闭加压气体到针的流动和药物流到针头,使得阀可以被操作以展开针并且通过针将药物递送通过针 用户已准备好进行注射。 当剂量完成时,也可以操作阀门以缩回针头。
