The end surface of the sampling tube 61 far away from the end of the guide groove is provided with a connecting port 64 communicated with the interior of the sampling tube, and the connecting port 64 is matched with a needle seat 81 on the needle cylinder 80. The spring 62 is disposed in the third communicating groove 18, a first end of the spring 62 is connected to the sampling tube 61, and a second end of the spring 62 is connected to a groove wall of the third communicating groove 18.
In the initial state, the withdrawal chimney 61 does not enter the collection area, which remains closed.
After removing the capsule body 10, the medical staff needs to remove the liquid sample in the capsule body 10.
The working process of taking out the liquid sample comprises the following steps: the medical staff inserts the needle holder 81 of the needle cylinder 80 into the third communicating groove 18 and into the connecting port 64 of the sampling tube 61. The needle cartridge 80 is then pressed inwardly, whereupon the spring 62 deforms and the collection aperture 63 of the sampling tube 61 enters the collection area 50, whereupon the medical professional pulls the plunger 83 of the cartridge body 82 and the entire liquid sample in the collection area 50 is aspirated into the cartridge body 82. Finally, the medical staff pulls out the needle cylinder 80 again to finish taking out the liquid sample, the sampling cylinder 61 is reset under the action of the spring 62, and the invention returns to the initial state.
