Fig. 2 is an enlarged schematic view of a portion a in fig. 1.
Detailed Description
As shown in fig. 1 and 2, the present invention includes a syringe 2, a needle 1 disposed on the syringe 2, a liquid collecting mechanism 3 for collecting blood, and a driving mechanism 4 for driving the needle 1 to move relative to the syringe 2 to puncture skin, wherein the syringe 2 includes an installation section 21 for installing the needle 1, the installation section 21 is provided with a needle channel 212 for the needle 1 to penetrate out, and the liquid collecting mechanism 3 includes:
a blood flow conduit 31 which is arranged in the mounting section 21 and communicated with the needle passage;
a vacuum canister 32 for storing blood;
a connecting conduit 33 which is arranged on the vacuum liquid collecting bag and is detachably connected with the blood flow conduit 31.
When the blood collecting device is used for collecting blood, the connecting conduit 33 is connected with the blood flow conduit 31, then the needle head 1 is driven by the driving mechanism 4 to penetrate out of the needle head channel so as to puncture the skin, after the blood comes out, the blood passes through the needle head channel, the blood flow conduit 31 and the connecting pipe in sequence due to the vacuum state of the vacuum liquid collecting cylinder 32 and finally enters the vacuum liquid collecting cylinder 32, and after the collection is finished, the vacuum liquid collecting cylinder 32 is separated from the blood flow conduit 31, and then the sterile sealing is carried out. If more blood samples need to be collected for the patient, a new vacuum liquid collecting cylinder 32 can be immediately replaced for collection.
