When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "first" and "second" used herein do not denote any particular order or quantity, but rather are used to distinguish one element from another.
Referring to fig. 1, a body fluid collecting device includes a storage container 10, a collector 20 and a blocking member 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.
Referring to fig. 2 and 5, the storage container 10 has a first storage chamber 101 and a second storage chamber 102, the first storage chamber 101 is communicated with the second storage chamber 102 through a communication port 103, the first storage chamber 101 is used for containing the preservation solution 40, and the storage container 10 further has an opening end 121 for communicating the second storage chamber 102 with the outside. The storage container 10 may be made of plastic or glass. As shown in fig. 4, the outside of the storage container 10 may be silk-screened, die-cut or otherwise processed with graduation marks 13 that identify the volume of saliva collected. In addition, the outer side of the storage container 10 may be printed, stamped or adhered with marks of product-related information such as product name and serial number, manufacturer and date, sample storage conditions, and the like.
Referring to fig. 2 and 6, the collector 20 is detachably connected to the open end 121, such as by a screw connection or a snap connection. It should be noted that the collector 20 and the open end 121 of the storage container 10 may be directly connected or indirectly connected by using an intermediate element, as long as the connection and the disconnection between the collector 20 and the storage container 10 can be realized. The collector 20 comprises a liquid collecting cup 21 and a flow guide tube 22, one end of the flow guide tube 22 is connected and communicated with the liquid collecting cup 21, the other end of the flow guide tube 22 is a closed blind tube end 221, the flow guide tube 22 is inserted into the storage container 10, the blind tube end 221 is used for plugging the communicating port 103, a buffer cavity 104 is formed between the flow guide tube 22 and the inner wall surface of the second storage cavity 102, a liquid outlet 222 is arranged on the peripheral surface of the flow guide tube 22, and the flow guide tube 22 is communicated with the buffer cavity 104 through the liquid outlet 222.
As shown in fig. 2 and 8, before use, the collector 20 and the storage container 10 are connected, and the communication port 103 is sealed by the blind end 221 of the delivery tube 22. The blind pipe end 221 and the communication port 103 can be sealed in an interference fit mode; alternatively, the blind pipe end 221 may be made of a flexible material such as rubber or silica gel to seal the communication port 103; alternatively, the communication port 103 may be sealed by providing a seal 223 at the blind end 221, and the specific sealing form is not limited as long as the preservation solution 40 in the first storage chamber 101 does not leak out. After collection, the harvester 20 is removed and the blind end 221 is separated from the communication port 103, thereby allowing the buffer chamber 104 to communicate with the first storage chamber 101.
The liquid outlets 222 are used for communicating the flow guide pipe 22 with the buffer cavity 104, and the shape and number of the liquid outlets 222 can be set according to actual requirements. Considering that saliva samples are generally viscous, it is preferred that the exit port 222 be elongated along the length of the flow conduit 22, as shown in fig. 6; and/or, two or more liquid outlets 222 are arranged on the circumference of the flow guide tube 22, so that the total liquid outlet area of the flow guide tube 22 is as large as possible, so that the saliva sample can flow into the buffer cavity 104 more quickly, and the collection efficiency is improved.
