    • This device is a compressible chamber designed to inject a liquid medication through a plurality of needles. It is a self-contained, rapidly deployed device that replaces a classic syringe. It consists of a shallow chamber that is closed on one end and sealed on the other with a sliding elastomeric seal. A rigid ring slides up into the chamber that has multiple small double-ended needles mounted through the periphery of the ring perpendicularly so as to be able to perforate the seal of the chamber with the proximal end and simultaneously penetrate the subcutaneous tissues with the distal end thus allowing medication to flow from the chamber into the tissues when pressure is applied to the top of the chamber. The needles are also imbedded in, or juxtapose to a ring of compressible dye-containing material that serves to conceal the needles and provide demarcation of the area injected.
    • 该装置是设计成通过多个针注射液体药物的可压缩室。 它是一个独立的,快速部署的设备,取代了经典的注射器。 它由一个浅的腔室组成,在一端封闭并用另一个弹性密封件密封。 刚性环向上滑入腔室,其具有穿过环的周边垂直安装的多个小双头针,以便能够使近端的腔室的密封穿孔,同时用远端穿透皮下组织 从而当压力施加到腔室的顶部时允许药物从腔室流入组织。 针也嵌入或并置到可压缩的含染料材料的环中,其用于隐藏针并提供注入区域的划分。

    • Systems and methods which determine the position of an instrument internal to an object using an opto-mechanical sensor are shown. Embodiments utilize an opto-mechanical sensor system in which a mechanical instrument interface provides instrument movement information to a corresponding optical sensor system to determine instrument movement. Determinations of instrument movement preferably provide information regarding movement direction and speed. Such information, when used in combination with other information such as starting position or starting position offset, insertion angle or angle of attack, and/or insertion plane, is utilized by embodiments of the invention to determine the position of an instrument or portion thereof. Embodiments are adapted to accommodate different instrument configurations. Position information may be utilized in combination with an ultrasound image to display a visual representation of the instrument, or portion thereof, within a object being imaged.
    • 示出了使用光机械传感器来确定物体内部的仪器的位置的系统和方法。 实施例使用光机械传感器系统,其中机械仪器接口将仪器移动信息提供给相应的光学传感器系统以确定仪器运动。 仪器移动的确定优选地提供关于运动方向和速度的信息。 当与本发明的实施例一起使用这种信息,以与其他信息(例如起始位置或起始位置偏移,插入角度或迎角)和/或插入平面组合使用以确定仪器或其部分的位置。 实施例适于适应不同的仪器配置。 位置信息可以与超声波图像结合使用,以在被成像的物体内显示仪器或其部分的视觉表示。
