By figure 1 to 4 and give, axial pjncture needle 1 about including, 1 left side of pjncture needle is equipped with sets up opening inlet port 2 up, 1 left end of pjncture needle is equipped with hose 3 with inlet port 2 intercommunication, 3 free ends of hose are equipped with fixed pipe 4 of axial about, logical groove 5 has been seted up to fixed 4 outer fringe faces of pipe, coaxial sliding connection has filter tube 6 in the fixed pipe 4, the downside is equipped with filter membrane 7 in the filter tube 6, fixed pipe 4 and coaxial bracelet 8 that are equipped with are stretched out to filter tube 6 upper end, the drain hole 9 that link up from top to bottom is seted up to 1 right side of pjncture needle, 1 lower extreme of pjncture needle is equipped with the transfer line 10 with drain hole 9 intercommunication.

The infusion device comprises a dropper 11 communicated with the interior of an infusion tube 10 and arranged on the lower side of the infusion tube 10, an infusion needle 12 is arranged at the tail end of the infusion tube 10, and a flow regulating valve 13 sleeved on the outer side of the infusion tube 10 is arranged between the dropper 11 and the infusion needle 12.

In order to realize that the filter tube 6 can close the through groove 5, the lower end of the filter tube 6 is coaxially provided with a rubber ring 14 which is contacted with the inner edge surface of the fixed tube 4.

In order to prevent dust from entering the fixed pipe 4 through the through slots 5, a filter 15 is coaxially arranged in the fixed pipe 4 and below the through slots 5.

In order to prevent the puncture needle 1 from contacting with air, a ring block 16 is coaxially arranged on the puncture needle 1, a sealing sleeve 17 which upwards wraps the puncture needle 1 is arranged at the upper end of the ring block 16, and the puncture needle 1 can puncture the sealing sleeve 17.

In order to realize that the filter tube 6 can filter viruses, the filter membrane 7 is made of melt-blown cloth materials.
