    • A catheter useful for non-surgical entry into the cervical canal of a uterus to dispense a diagnostic fluid therein. The catheter includes a tubular body having a lumen extending from a first end thereof to a second end thereof. The lumen includes a first aperture at or adjacent to the first end for dispensing a diagnostic fluid into the interior of a subject uterus, and a balloon disposed marginally adjacent to the first end of the body for fluid sealing the interior of the subject uterus. The lumen further includes a second aperture in fluid communication with the interior of the balloon for inflation thereof with the diagnostic fluid. The area of the first aperture is less than the area of the second aperture to provide a backpressure that inflates the balloon when a diagnostic fluid is injected through the catheter. In most applications, the catheter can be combined with a syringe to form a catheter apparatus.
    • 用于非手术进入子宫颈管以在其中分配诊断流体的导管。 导管包括管状体,其具有从其第一端延伸到其第二端的内腔。 内腔包括在第一端处或与第一端相邻的第一孔,用于将诊断流体分配到被检体子宫的内部,以及气囊,其与身体的第一端稍微相邻地设置,用于流体密封受检子宫的内部。 内腔还包括与气囊内部流体连通的第二孔,用于与诊断流体一起使其膨胀。 第一孔的面积小于第二孔的面积,以提供当诊断流体通过导管注射时气囊膨胀的背压。 在大多数应用中,导管可以与注射器组合以形成导管装置。
