When injecting distilled water into an antibiotic powder or drug solution previously stored in a vacuum bottle and mixing it, inject an air needle into the distilled water bottle and then insert a syringe needle into both ends of a vinyl tube. Deeply pierce one needle of the combined connecting device, then pierce the other needle into a bottle storing antibiotic powder or drug solution, etc., and suck and transfer distilled water into the vacuum bottle. Mix the drug and distilled water. However, if gas is generated inside the vacuum bottle, the degree of vacuum in the vacuum bottle will be lost, making it difficult to suction and transfer sufficient distilled water into the vacuum bottle using the mixing method described above. There is. Therefore, in view of these problems, it is an object of the present invention to provide a mixing needle that allows the mixing of chemical solutions to be extremely easy and the transfer of chemical solutions to be performed smoothly even in the case of vacuum or normal pressure. Next, the present invention will be explained in detail with reference to the drawings of one embodiment.

When mixing distilled water 1 and a drug such as antibiotic powder or liquid medicine, first pierce the distilled water bottle 1a with the air needle 3, then pierce the syringe needle 4a of the vinyl connecting tube 4 into the bottle 1a, and then tighten the clamp 4b. The switch is closed and the other injection needle 4c of the tube 4 is inserted into the vacuum bottle 2b. Next, open the switch of clamp 4b,
Distilled water 1 is suctioned and transferred to bottle 2b. In this case, distilled water 1
cannot be absorbed. FIG. 2 is a side sectional view of one embodiment of the present invention. The needle base 6 that holds the medicinal liquid bottle of the needle tube 5 having two passages is provided with a plurality of grooves in the vertical direction on the inner wall of a tubular portion 6p that can be pierced in close contact with the outer peripheral surface of the needle tube 5. is formed. A filter 7n is provided at the air intake port 6bn of the air passage 6an to prevent backflow of the chemical solution. FIG. 3 is a sectional view taken along the line AA in FIG. 2. FIG. 4 is a side sectional view showing an example of use of the device shown in FIG. Distilled water 1' in bottle 8 is transferred into vacuum bottle 9 and mixed with drug 2'. The gas 10 in the vacuum bottle 9 is transferred into the bottle 8, and the distilled water 1' is smoothly transferred. Furthermore, when the air passage 6an side is pierced into the vacuum bottle 9, the gas 10 in the vacuum bottle 9 escapes to the outside and becomes normal pressure, and the distilled water 1' in the bottle 8 is smoothly transferred, and the drug 2' Mix with. A filter 7n was installed at the air sampling port 6bn to prevent distilled water 1' etc. from flowing back out. The smaller the mesh of the filter 7n, the more effective it is. As described above, the needle base 6 has a plurality of air passages 6an and a filter 7n.
, the chemical solution can be mixed smoothly even under vacuum pressure or normal pressure.
