    摘要： The invention faces the technical problem of reducing the uncertainty over exact doses ejected from a medical device and at the same time providing a homogeneous, but controlled mixture of at least two fluids while a simple production should be maintained. A medical device comprising a first valve, a second valve, a first pre-valve ullage, a second pre-valve ullage, a post-valve ullage with a first end and a second end and a needle is presented. The first pre-valve ullage is connected to the post-valve ullage by the first valve and the second pre-valve ullage is connected to the post-valve ullage by the second valve. A first fluid is guidable from the first pre-valve ullage to the post-valve ullage and a second fluid is guidable from the second pre-valve ullage to the post-valve ullage.

    摘要翻译： 本发明面临技术问题，即降低从医疗装置喷出的精确剂量的不确定性，同时提供至少两种流体的均匀但可控的混合物，同时应保持简单的生产。 一种医疗装置，其包括第一阀，第二阀，第一预阀缺口，第二预阀缺口，具有第一端和第二端的后阀缺口和针。 第一个阀门前端通过第一个阀门连接到后阀门，第二个阀门前端通过第二个阀门连接到后阀门。 第一流体可以从第一个阀门前后移动到后阀闭合，第二个流体可以从第二个预阀闭合引导到后阀闭合。
