Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an end tube connector and a matching container. Background Technology

[0002] In the field of component blood collection, high-end apheresis equipment and consumables have always been mainly imported products. In order to facilitate the compact design and centralized control of the equipment structure, such products generally have a pipeline control box set up to control the flow rate, direction, pressure and quality of blood and blood cells in the external circulation part.

[0003] Currently, all existing container structures on the market are one-piece structures, that is, the container is made into two parts, an upper shell and a lower shell, according to the product structure. Each pipeline is a half-section structure on the upper and lower shells. After the upper and lower shells are welded together, the pipelines form a complete closed cavity. However, due to the independence of each pipeline, the welding area of ​​the upper and lower shells is large, the selection of welding equipment is narrow, and the selection of parts materials is also narrow due to welding performance, medical grade requirements and other reasons. The injection molding conditions of this material are demanding and the deformation temperature is low, resulting in low processing efficiency. To address this, the applicant modified the design to include a top cover, a box body, and several prefabricated pipes. The top cover and box body are detachably connected to form a container, and the prefabricated pipes are detachably connected inside the container. At least one end of each prefabricated pipe is confined within a limiting hole opened on the side wall of the container. However, during use, the inventors discovered that due to the different functions of each pipe, the ends of some pipes need to extend outside the container to connect with the peristaltic pump, while the ends of some pipes do not need to extend outside the container to connect with consumables. However, if the ends of each pipe are designed with the same structure, it is impossible to confine the ends of each pipe to the side wall of the container.

[0004] Therefore, there is an urgent need for an end pipe connector and a matching container. Utility Model Content
