Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mixing needle for injecting and mixing distilled water into a powdered anti-inflammatory substance stored in a vacuum bottle. The conventional mixing needle has the function of adjusting the flow rate inside the pipe by installing a vinyl chloride pipe with the desired outer diameter and length, connecting a syringe needle to both ends of the pipe, and installing a clamp in the middle of the pipe. A mixing needle set is constructed by providing a mixing needle as an assembly, and adding an air needle and a safety needle cover to the needle body. In actual use, there are some inconveniences: the bottle storing distilled water must be hung upside down, and the mixing needle is always exposed to the outside, so it can be contaminated with bacteria. It is not hygienic as it is used by direct contact with hands and fingers, and each time the distilled water is transferred, the clamp installed on the pipe must be operated to prevent the distilled water from flowing out. It was inconvenient to handle.

Therefore, the present invention solves these inconveniences and provides a double-edged mixing needle that is easy to use and makes it possible to mix distilled water in a sanitary manner.

Next, the present invention will be explained in detail with reference to drawings of one embodiment thereof.

FIG. 1 is an external appearance diagram of a conventional mixing needle set. The conventional mixing needle has a needle base 1a on the injection needle 1, and the needle base 1a of the injection needle 1 is connected to both ends of a vinyl chloride tube having a desired outer diameter and length, and the tube is A clamp 3 for flow rate adjustment is provided between the two to form an assembly. The injection needle 1, which is similar to the injection needle 1, is a pneumatic needle. Those injection needles 1,
1' is fitted with safety needle covers 1b, 1b'.

FIG. 2 is a side cross-sectional view of an embodiment using the conventional set of mixing needles 1 of FIG. Hang the bottle A containing distilled water A2 upside down on the hanging tool 4, and insert the mixing needle 1 into the bottle stopper A1.
pierce through. In this case, the clamp 3 is operated to stop the flow of the vinyl chloride pipe 2 so that the distilled water A2 does not leak out accidentally. Next, one of the injection needles 1 is inserted into the bottle stopper of the vacuum bottle B. The attached air needle 1' serves to pierce the bottle stopper A1 of bottle A to introduce air. Next, when the clamp 3 is loosened, the distilled water A2 is sucked into the vacuum bottle B and transferred. Powdered anti-substance B2 in vacuum bottle B
is dissolved and mixed in the distilled water A2 that was injected by suction.
When the required amount of distilled water A2 has been transferred, the clamp 3 is tightened to stop the transfer of distilled water A2.

FIG. 3 is a side view of the external appearance of an embodiment of the present invention. Both ends of the double-edged mixing needle 5 have needle covers 6a, 6b attached to their cutting edges 5a, 5b. Inside the bag body 7, which is a holder, are the mixing needle 5 and the needle tip 5a,
The mixing needle 5 is assembled with the safety needle covers 6a, 6b still attached to the needle 5b. The bag 7 serving as the holder may be made of vinyl chloride or the like and may be transparent or opaque. The wall thickness of the bag body 7 may be such that it does not easily break under the pressure applied when piercing the bottle stopper.

FIG. 4 is a sectional view taken along the line AA in FIG. 3.

FIG. 5 is a side view sectional view showing one usage mode of an embodiment of the present invention. Bottle stopper A for distilled water bottle A
1 through the mixing needle 5 with the cutting edge 5a of the mixing needle 5 until it reaches the bottom of the bottle A. Next, holding the vacuum bottle B with the left hand HL, and holding the bag body 7 which is a holding body of the mixing needle 5 with the right hand HR, insert the cutting edge 5b of the mixing needle 5 into the bottle stopper B1 of the bottle B. Since bottle B is a vacuum bottle,
Immediately aspirate distilled water A2 in bottle A. Bin A
When the air pressure in bottle B becomes negative, distilled water A2 flows into bottle B.
Therefore, the air needle 1' is inserted into the bottle stopper A1 to allow air to be introduced. As described above, since the mixing needle 5 has the bag body 7 which is a holder, it can be pierced through the bottle stoppers A1 and B1 without directly touching it with the hands or the like. Distilled water bottle A can be placed on the desk or stand 9 in normal condition without worrying about distilled water A2 falling, and distilled water A
2 to the vacuum bottle B, the vacuum suction force makes it easy to fill the bottle B to 90% of the volume, and the mixing needle 5 is curved and pierced into the bottle B, and the distilled water A2 is transferred to the vacuum bottle B.
It became possible to quickly transfer the contents from one bin B to the next.

As described above, according to one embodiment of the present invention, it is possible to eliminate the previous inconvenience and transfer distilled water A2 to vacuum bottle B extremely easily and simply and quickly, and Powdered anti-substance B2 in bottle B
The mixing needle 5 is made to have appropriate bending elasticity so that the cutting edge 5b will not be contaminated by falling inside the container, and the mixing needle 5 is characterized by highly efficient dissolution and mixing of the powdered anti-substance B2 in mixing the drug solution. ing.
