Referring to fig. 1 and 6, a body fluid collecting device includes a storage container 10, a blocking member 20, and a collector 30. The body fluid collecting device can be used for collecting and storing saliva samples, but not limited to collecting and storing saliva samples, and can also be used for collecting and storing other body fluids. The following description will mainly take the collection and storage of saliva samples as an example.
The storage container 10 can be used for storing a preservative solution before saliva collection and storing a mixed solution of the preservative solution and saliva after the saliva collection is completed. The storage container 10 has an open end 11 for communicating with the outside, and the storage container 10 may be provided in a tubular or bottle-like structure. The storage container 10 may be made of plastic or glass. The outside of the reservoir 10 may be silk-screened, die-cut or otherwise processed with graduation marks 12 identifying the volume of saliva collected. The outer side of the storage container 10 may be printed, molded or pasted with a logo of product-related information such as product name and number, manufacturer and date, sample storage condition, etc.
Referring to fig. 2 and 5, the blocking member 20 includes a mounting seat 21 and a sealing cover 22 movably connected to the mounting seat 21, the mounting seat 21 has a first open end and a second open end that are mutually communicated, the first open end is connected to the open end 11 in a sealing manner, and the sealing cover 22 is used for opening or sealing the second open end
Specifically, the first open end of the mounting seat 21 and the open end 11 of the storage container 10 may be connected by a screw connection or a snap connection, and after the connection, sealing may be achieved by interference fit, additional sealing ring, and the like, and the specific sealing structure may be a side sealing structure, an end sealing structure, or a combination of the two. That is, the above-described sealing structure may be a single-piece cap (no gasket cap) sealing structure, a double-piece cap (gasket cap) sealing structure, or a seal ring sealing structure. The sealing cover 22 is hinged to the mounting base 21 by a connecting piece 23 and can be freely turned over relative to the mounting base 21. The sealing cover 22 and the second open end can be sealed by interference fit, additional sealing ring, etc., and the specific sealing structure can be a side sealing structure, an end sealing structure, or a combination of the two. In this way, the two ends of the mounting seat 21 can be respectively matched with the storage container 10 and the sealing cover 22 in a sealing manner, so that the sealing reliability between the plugging piece 20 and the storage container 10 is ensured, and the liquid in the storage container 10 is prevented from leaking.
The collector 30 is used for collecting body fluid (e.g. saliva), the collector 30 comprises a liquid collecting cup 31 and a flow guide tube 32, one end of the flow guide tube 32 is connected and communicated with the liquid collecting cup 31, the other end of the flow guide tube 32 is detachably inserted into the second open end, and the liquid collecting cup 31 is communicated with the storage container 10 through the flow guide tube 32. When saliva collection is needed, the flow guide pipe 32 is inserted into the second open end, and the saliva collected by the liquid collecting cup 31 can flow into the storage container 10 through the flow guide pipe 32; after the collection is completed, the draft tube 32 is pulled out.
The storage container 10 of the body fluid collecting device is filled with a preservation fluid in advance, and the open end 11 of the storage container 10 is hermetically closed by a sealing cover 22 to hermetically preserve the preservation fluid.
