Problems solved by technology

This kind of structure leads to more cumbersome molds in production, low yield and low processing efficiency
[0003] Secondly, in the prior art, the liquid guiding channel and the exhaust channel share a side wall, and the side wall of the liquid guiding channel and the side wall of the exhaust channel together form a connecting side wall, so the liquid guiding channel can only be a single channel, resulting in a slow flow rate. slow
[0004] Furthermore, when the liquid-taking part is separated from the test tube and the test-tube assembly in the prior art, the residual liquid in the liquid-guiding channel below the bottom plate of the liquid-taking part is easy to spill, causing pollution.

Abstract

The invention relates to a medical apparatus, in particular to a device for acquiring body fluid, and provides a fluid taking member for a sealed body fluid retention apparatus. The fluid taking member comprises an acquisition side wall, a bottom plate, a channel and a connecting side wall, wherein the acquisition side wall is used for gathering fluid; the bottom plate is located at the bottom ofthe acquisition side wall and is connected with the acquisition side wall; the bottom plate and the acquisition side wall are integrated; an acquisition container is formed by the acquisition side wall and the bottom plate; the channel comprises an exhaust channel and one or more fluid guiding channels, and the exhaust channel and the fluid guiding channels penetrate through the bottom plate; theconnecting side wall is formed in a manner that the lower surface of the bottom plate extends downwards; the connecting side wall is used for cooperating with an opening part of a test tube; the exhaust channel and the fluid guiding channels are located on the inner side of the connecting side wall, on the lower surface of the bottom plate; and no coinciding part between the connecting side wall and the side wall of the exhaust channel or one or more fluid guiding channels below the lower surface of the bottom plate is generated. The fluid taking member disclosed by the invention has the advantages of being easy to work, high in fluid guiding efficiency and high in processing efficiency, raw materials are saved, and pollution is not liable to cause.

Description

technical field [0001] The present invention relates to medical devices, and more particularly to devices for collecting body fluids. Background technique [0002] In the prior art liquid-taking part for the airtight body fluid indwelling device, the connection side wall used for the connection between the liquid-taking part and the test tube is actually formed jointly by the side wall of the liquid guide channel and the side wall of the exhaust channel. Such a structure leads to complex molds in production, low yield and low processing efficiency. [0003] Secondly, in the prior art, the liquid guiding channel and the exhaust channel share a side wall, and the side wall of the liquid guiding channel and the side wall of the exhaust channel together form a connecting side wall, so the liquid guiding channel can only be a single channel, resulting in a slow flow rate. slow. [0004] Furthermore, in the prior art, when the liquid taking part is separated from the test tube...
