The puncture outfit 101 provided by the embodiment of the application comprises a puncture body 1011, a connection body 1012 and an annular protrusion 1013, wherein the puncture body 1011 is used for puncturing the bottle stopper 30 so as to realize medicine preparation, the connection body 1012 is connected with the puncture body 1011, the connection body 1012 is used for being in sealing connection with the syringe 200 so that medicine liquid flows into the syringe 200 through the puncture body 1011, the annular protrusion 1013 is arranged on the connection body 1012, and the annular protrusion 1013 is used for being in contact with and propped against the bottle stopper 30 after the puncture body 1011 punctures the bottle stopper 30.

It can be understood that the existing puncture outfit 101 mainly wraps the penicillin bottle 20 through the cap structure to ensure the sterile environment, however, the wrapped cap structure is not only complex in structure and inconvenient for mass production, but also shields the puncture position of the puncture needle tip and inconvenient for observing the residual liquid medicine amount, and in addition, the puncture outfit 101 can be sleeved on the penicillin bottle 20 only by distinguishing different specifications due to different specifications of the penicillin bottle 20, so that the operation is inconvenient. Compared with the traditional puncture outfit 101, the puncture outfit 101 provided by the embodiment of the application cancels the cap structure and adds the annular protrusion 1013, the annular protrusion 1013 is arranged on the connecting body 1012, and the annular protrusion 1013 is used for contacting and propping against the bottle stopper 30 after the puncture body 1011 pierces the bottle stopper 30.

Thus, on the one hand, the annular protrusion 1013 is in contact with the stopper 30 to maintain sterility of the puncture hole in the stopper 30; on the other hand, the annular protrusion 1013 is adopted to replace the cap structure, the sleeve joint is not needed, the medicine dispensing and puncturing can be carried out on the penicillin bottles 20 with different specifications, the universality is greatly improved, and meanwhile, the protrusion structure is free from shielding, so that the position of the puncturing body 1011 and the residual medicine amount can be conveniently observed.

In some embodiments, to facilitate connection of the penetrator 101 with the syringe 200, the connection body 1012 is provided with a lumen 10122, the lumen 10122 for insertion of the tapered end 201 of the syringe 200.

Specifically, the conical head end 201 of the syringe 200 is inserted into the inner cavity 10122 with the taper of 6:100 along the axial direction thereof, so as to realize the sealing connection between the syringe 200 and the puncture outfit 101.

In some embodiments, to further enhance the connection reliability and reliability of the syringe 200 and the puncture outfit 101, the connection body 1012 is provided with a first rotating connection structure 10121 for connecting the syringe 200, and correspondingly, the syringe 200 is provided with a connector 300, and the connector 300 is provided with a second rotating connection structure 301 connected with the first rotating connection structure 10121.

Specifically, the connector 300 is a luer lock connector 300, the second rotary connection structure 301 is an internal thread provided on the inner wall of the connector 300, and the first rotary connection structure 10121 is a lug distributed along the circumferential direction of the connection body 1012, and of course, the number of lugs may be two. In this way, the syringe 200 with the luer lock connector 300 is connected to the puncture outfit 101 by the double lugs, and during the rotation process of connection, the lugs are screwed in the internal threads of the luer lock connector 300, and at the same time, the conical head end 201 of the syringe 200 is inserted into the inner cavity 10122 with the taper of 6:100 along the axial direction, so as to realize the sealing connection of the syringe 200 and the puncture outfit 101.

In some embodiments, the puncture body 1011 includes a needle 10111 and a needle 10112, the needle 10112 is provided with a medicine inlet 10113 and a runner 10114 communicating with the medicine inlet 10113, the runner 10114 communicates with the conical head 201 of the syringe 200, so as to ensure that when the puncture body 1011 punctures the penicillin bottle 20 and the annular protrusion 1013 contacts the bottle stopper 30, the medicine liquid in the penicillin bottle 20 enters the syringe 200 through the medicine inlet 10113 and the runner 10114.

It should be noted that, in the prior art, the drug inlet hole 10113 of the puncture body 1011 is shorter, and the length of the puncture body 1011 is longer, which is easy to cause residual liquid medicine in the penicillin bottle 20 and waste the liquid medicine in the process of taking back the syringe 200 again when the penicillin bottle 20 is dispensed. If the puncture outfit 101 needs to be pulled axially in order not to waste the medical fluid, the medical fluid can be ensured to return to the syringe 200 through the medicine inlet 10113 on the puncture body 1011.

It should be noted that the embodiment of the present application improves the drug inlet 10113 such that the drug inlet 10113 extends into the interior of the stopper 30 when the annular protrusion 1013 contacts and abuts against the stopper 30, thereby ensuring that the drug solution can flow back into the syringe 200 without residue.

More specifically, after the sharp needle 10111 of the puncture body 1011 penetrates the vial stopper 30 of the penicillin bottle 20, the medicine in the syringe 200 and the medicine in the penicillin bottle 20 can be mixed by communicating the runner 10114 with the syringe 200. After mixing, the penicillin bottle 20 is inverted, that is, the needle 10111 faces upwards, so that the mixed medicament in the penicillin bottle 20 flows back into the syringe 200 through the medicament inlet hole 10113 as much as possible (the process of extracting the medicament liquid), and since the length of the medicament inlet hole 10113 is long (the length can ensure that the medicament inlet hole 10113 extends into the bottle stopper 30 when the annular protrusion 1013 contacts and abuts against the bottle stopper 30 so as to avoid residual medicament liquid), a large height difference is not formed between the medicament inlet hole 10113 and the inner wall of the bottle stopper 20, and therefore, almost no medicament remains in the penicillin bottle 20, medicament can be saved, and the medicament is beneficial for improving the accurate control of the administration amount.
