摘要： An endometrial sampler is provided for obtaining an endometrial sample for clinical analysis which is safe to use and reduces patient discomfort. The sampler includes a handle and a flexible plastic probe having grooves on diametrically opposite sides adjacent the distal end of the probe. Each groove has a pair of sharp edges with each edge formed at the intersection of the periphery of the probe and a sidewall of the groove with the two forming an acute angle at their intersection. The probe is of solid plastic, relatively small in diameter and can be bent before insertion into the uterus of a patient to reduce patient discomfort.

摘要： A fluid collection device is provided which includes a container for receiving a liquid, such as blood, that is centrifugally separable into relatively light and heavy phases, and a phase partitioning device in the container. The partitioning device includes a thixotropic gel-like material adjacent one end of the container having a specific gravity between the specific gravities of the light and heavy phases, and a piston member having an outlet in communication with the sealant so that during centrifugation of the device, centrifugal forces cause the piston to pressurize the sealant and force the sealant through the outlet toward the interface of the phases with sealant forming a partition between the separated phases.
摘要翻译：提供了一种流体收集装置，其包括用于接收诸如血液的液体的容器，所述容器可离心分离成相对较轻和重的相，以及容器中的相分配装置。分隔装置包括邻近容器的一端的触变性凝胶状材料，其比重在轻相和重相的比重之间;以及活塞构件，其具有与密封剂连通的出口，使得在装置的离心期间离心力使活塞对密封剂加压，并迫使密封剂通过出口朝向相的界面，密封剂形成分离相之间的分隔。
