发明名称 Mating mechanism for a pressurizing unit and corresponding sleeve in a medical fluid injection device
摘要 In general, this disclosure relates to techniques for providing a mating mechanism between at least one pressurizing unit and at least one corresponding sleeve in a powered medical fluid injection device. An example powered medical fluid injection device includes a sleeve and an injector head coupled to the sleeve. The sleeve has a notch with a predefined shape and size. The sleeve is configured to receive a pressurizing unit (such as a syringe) having an external tab with a predefined shape and size that are substantially identical to the predefined shape and size of the notch in the sleeve, such that the tab mates with the notch when the sleeve receives the pressurizing unit. The injector head is configured to inject a quantity of a medical fluid from the pressurizing unit during operation.

主权项 1. A method comprising: receiving a pressurizing unit within a sleeve of a powered medical fluid injection device, such that the pressurizing unit is contained within the sleeve, wherein the sleeve has a notch with a predefined shape and size, and wherein the pressurizing unit has an external tab with a predefined shape and size that are substantially identical to the predefined shape and size of the notch in the sleeve, such that the notch mates with the tab when the sleeve receives the pressurizing unit; receiving a second pressurizing unit within a second sleeve of the powered medical fluid injection device, such that the second pressurizing unit is contained within the second sleeve, wherein the second sleeve has a second notch with a predefined shape and size substantially different than the predefined shape and size of the notch of the sleeve, and wherein the second pressurizing unit has a second external tab with a predefined shape and size that are substantially identical to the predefined shape and size of the second notch of the second sleeve, such that the second notch of the second sleeve mates with the second external tab of the second pressurizing unit when the second sleeve receives the second pressurizing unit, wherein the predefined shape and size of the notch of the sleeve are substantially different from the predefined shape and size of the second external tab of the second pressurizing unit, such that the predefined shape and size of the notch of the sleeve prohibits the second pressurizing unit from being received within the sleeve, and wherein the predefined shape and size of the second notch of the second sleeve are substantially different from the predefined shape and size of the external tab of the pressurizing unit, such that the predefined shape and size of the second notch of the second sleeve prohibits the pressurizing unit from being received within the second sleeve; and injecting a quantity of a medical fluid contained within the pressurizing unit or the second pressurizing unit using the injection device.
