[Detailed Description of the Invention] The present invention relates to a mixing needle for mixing medical liquids. Previously, when injecting distilled water into an antibiotic powder or drug solution stored in a vacuum bottle and mixing it, an air needle was injected into the distilled water bottle, and then a syringe needle was inserted at both ends of a vinyl tube. Deeply pierce one needle of the connecting device with which the The drug and distilled water are mixed. However,
When gas is generated inside the vacuum bottle, the degree of vacuum in the vacuum bottle is lost, and it may be difficult to suction and transfer sufficient distilled water into the vacuum bottle using the mixing method described above. Therefore, in view of these problems, it is an object of the present invention to provide a mixing needle that allows the mixing operation of chemical liquids to be extremely easy and the transfer of chemical liquids to be carried out smoothly even in the case of a vacuum or normal pressure. Next, the present invention will be explained in detail with reference to the drawings of one embodiment. FIG. 1 is a side sectional view of a conventional embodiment. When mixing distilled water 1 and drugs such as antibiotic powder or liquid medicine, insert the air needle 3 into the distilled water bottle 1a,
Next, insert the injection needle 4a of the vinyl connecting tube 4 into the bottle 1a.
The injection needle 4c of the other end of the tube 4 is inserted into the vacuum bottle 2b with the clamp 4b switched to closed. Next, the switch of the crank 4b is opened to suction and transfer the distilled water 1 to the bottle 2b. In this case, distilled water 1
cannot be aspirated. 2 and 3 are side sectional views of an embodiment of the present invention. FIG. 2 shows a needle base 6 for holding a medicine bottle in a needle tube 5 having two passages.
A filter 7 is provided at the air sampling port 6b in close contact with the tube wall on the side of the tip of one of the blades 5a of the needle tube 5 to prevent backflow of the drug solution. Figure 3 shows the air passage 6
The blade 5a has an air passage 6a' for the blade 5a.
There is also an air passage 6 in the pipe wall on the side of the tip of the blade 5a'.
A' is provided in close contact with the air intake port 6b', and a filter 7' is provided at the air intake port 6b'. FIG. 4 is a side cross-sectional view showing an aspect of one usage example of FIG. 2. FIG. Place the distilled water bottle 8 on top and pierce the needle tube on the blade 5a side.
Pierce the a' side into the vacuum medicine bottle 9 and add distilled water 1'
is transferred to the lower vacuum bottle 9 and the drug 2' is mixed therein. The outside air is introduced into the bottle 8 from the air passage 6a, and the distilled water 1' is accelerated into the bottle 9, and the gas 10 filling the bottle 9 is transferred into the bottle 8, and the distilled water 1' is transferred into the bottle 8. ′ is transferred and mixed smoothly without interruption. FIG. 5 is a side sectional view showing an example of use of the device shown in FIG. Distilled water 1' is transferred into vacuum bottle 9. Gas 1 in vacuum bottle 9
0 is moved into bin 8. Furthermore, depending on the pressure of the gas 10, it may escape to the outside through the air passage 6a'. Outside air is introduced into the bottle 8 through the air passage 6a, and the transfer of the distilled water 1' is accelerated. Further, in FIGS. 4 and 5, the filters 7 and 7' serve to prevent the chemical liquid such as distilled water from flowing out to the outside, so that the chemical liquid is prevented from flowing out during the operation. As described above, according to one embodiment of the present invention, the air passage 6 is provided in the needle base 6.
Air passages 6a, 6a' are provided only on a or on both sides,
Even in the case of vacuum pressure or normal pressure, the chemical liquid mixing can be carried out smoothly without interruption.
