Example Embodiment

[0050] Example 1

[0051] Such as Figure 1-5 Example 1 is shown. The detection device 100 includes a cup body 11 and a cup cover 13. The cup body 11 includes a liquid sample collection chamber 111, a piston chamber 16 and a piston 15. The cover 13 has threads, and the cup 11 has threads matching it. The cover 13 and the cup 11 can cooperate and seal with each other. The side wall 115 of the cup 11 has a detection cavity 18 for accommodating the detection element 14. There are two sealing rings 19 between the piston 15 and the piston chamber 16. The longitudinal section of the piston chamber 16 and the piston 15 is funnel-shaped. The inner walls 164, 165, 166 of the piston chamber and the outer walls 155, 156, 157 of the piston define transfer Cavity 17. The openings 163 and 168 at both ends of the piston chamber 16 form two openings 171 and 172 of the transfer chamber 17. The piston 15 has a large diameter at one end and a small diameter at the other end. Correspondingly, th...

[0052] Example 2

[0053] The difference from Embodiment 1 is that a push rod 252 is connected to the cover 23, and the other end of the push rod 252 is connected to the piston 25. The piston 25 of the device 200 and the piston chamber 26 corresponding to the piston are cylinders with approximately the same diameter. The piston 25 includes an opening 251. The diameter of the opening 251 is smaller than the inner diameter of the piston chamber 26. The opening 251 and The inner wall 264 of the piston chamber 26 defines a transfer chamber 27 to allow the liquid sample to be transferred from the collection chamber 211 to the detection chamber 28. The openings 263 and 268 at both ends of the piston 25 form two openings 271 and 272 of the transfer chamber 27. The piston 25 also includes a protrusion 256 and the piston cavity includes a bayonet 265 mated with the protrusion. The protrusion 256 and the bayonet 265 form a blocking element. When the piston 25 moves from the first positio...

[0054] Example 3

[0055] This example Figure 11-15 As described, the detection device 300 includes a cup body 31 and a cover body 33. The cup body 31 includes a liquid sample collection cavity 311, a piston cavity 36 and a piston 35. There are threads on the cover body 33, and the cup body 31 is provided with threads that cooperate with it, and the cover body 33 and the cup body 31 can cooperate and seal with each other. A push rod 331 is provided on the cover 33. One end of the push rod 331 is connected to the cover 33 and the other end is used to close the opening 371 of the transfer cavity 37. At the bottom of the collection chamber 311, a piercing element 366 is arranged to pierce the closed end of the transfer chamber. The side wall 315 of the cup 11 has a detection cavity 18 for accommodating the detection element 14. In addition, a hole 367 is opened at the bottom of the collection cavity 36, and the liquid from the transfer cavity 37 can enter the detection cavity 38 ...

Abstract

The invention relates to a device for analyzing an analyte in a liquid sample. The device can be used for acquiring the liquid sample and simultaneously detecting whether the analyte exists in the sample or not. The device comprises a collection chamber for storing the liquid sample, a detection chamber for accommodating a detection element and a liquid sample transfer chamber, wherein the transfer chamber is connected with the detection chamber and the collection chamber, and the detection chamber is not in direct liquid communication with the liquid sample collection chamber; the transfer chamber is provided with a first position and a second position; when the transfer chamber is positioned in the first position, the transfer chamber is opened to the collection chamber and closed to the detection chamber and can receive a part of liquid sample in the collection chamber to the transfer chamber; and when the transfer chamber is positioned in the second position, the transfer chamber is closed to the collection chamber and opened to the detection chamber and can release the liquid sample in the transfer chamber to the detection chamber. The liquid sample is transferred to the detection chamber from the collection chamber through the transfer chamber so as to carry out detection or test, therefore, the pollution to the liquid sample in the collection chamber from the detection element in the detection chamber is avoided.

Description

technical field [0001] The invention belongs to the field of liquid sample collection, in particular to the field of collecting liquid samples and detecting analytes in the samples, especially the rapid diagnostic detection for detecting whether the samples contain metabolites of drug abuse substances or women's pregnancy. Background technique [0002] In recent years, detection devices have been widely used to detect analytes in human body fluids, such as urine, saliva or blood, such as indicators of drug abuse or disease. Such conventional detection devices usually need to collect a liquid sample into a container, then insert a test element into the liquid and then take it out to read (with naked eyes or with a machine) the test result on the test element. This has the potential to contaminate the operator with the sample. In addition to being used by professional inspectors, this detection device is gradually used by people without professional experience, for example, a...
