Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a portable ampere cutter used in the medical field.

[Prior art] In the past, the traditional method of cutting glass ampoules by making scratches with a chisel has been replaced by the easy-cut method in which fragile parts such as point scratches are provided in advance at the cutting location. There was a feeling of reluctance to cut directly with one's fingers, and a sense of hesitation accompanied by the fear of damaging the fingertips with glass shards.

[Problems to be solved by the invention] The present invention safely and reliably cuts the conventional Easy Cut ampoule at the point wound without touching it directly, and holds the cut ampoule head intact. For this purpose, we developed a medical ampere cutter that can be safely ejected into a disposal container for glass fragments.

[Means for Solving the Problems] The present invention is constructed to achieve the above-mentioned object, and the inner cylinder 3, which has passed through the through hole 2, is fixed at a proper position inside the outer cylinder 1, and At the tip of the inner cylindrical body 2, several pieces of elastic pieces 4 are connected to a tea whisk-shaped constriction part 4a and the constriction part 4.
A slide shaft 6 protruding in combination with a widened portion 4b from a and having a pressing head 5 at its tip is passed through the through hole 2, and a coil spring 7 is inserted from the rear end of the slide shaft 6. exterior,
Push the cap 8 into the rear end of the slide shaft 6.
is fixed and moved in and out of the rear part of the outer cylinder 1, and furthermore, a notch 9 is provided at the tip of the outer cylinder 1, and a protruding piece 11 is horizontally installed in the remaining tip 10. It is what it is. The pressing head 5 engages with the edge of the opening at the tip of the through hole 2 provided in the inner cylindrical body 3, and is fitted with a cap in the inner cavity of several elastic plates 4 that are combined and protruded from the tip of the inner cylindrical body 3. It is constructed so that it can be penetrated by pushing in 8.

[Function] The present invention is constructed as described above, and the head 14 of the ampoule 13 is connected to the arrow line 15 attached to the top of the notch 9 from the tip notch 9 of the outer cylinder 1.
and a mark 16 attached to the head 14 of the ampoule 13.
Insert the ampoule 13 while aligning the
The tip 10 of the outer cylindrical body 1 is inserted and held inside several pieces of elastic plates 4 squeezed into the shape of a tea whisk, which are protruded from the tip of the inner cylindrical body 3 so as to adjust the diameter of the inner cylindrical body 3.
The neck 1 of the ampoule 13 is attached to the protruding piece 11 installed horizontally on the
7, and while fixing the lower part of the ampoule 13, push the upper part of the outer cylinder body 1 with your fingertip using the protruding piece 11 as a fulcrum to easily remove the point scratch 18. It breaks. Furthermore, the broken head 14 of the ampoule 13 remains in the elastic plate 4, and when it is lowered with the fingertip of the push-in cap 8, the coil spring 7 is compressed and the slide shaft 6 is inserted into the through hole of the inner cylinder 3. 2, the pressure head 5 at the tip is pushed down, and the glass fragments can be ejected directly from inside the elastic plate 4 into the glass fragments processing container without touching it. Note that several elastic plates 4 are combined and protruded from the tip of the inner cylindrical body 3, forming a constricted portion 4a and an expanded portion 4.
b, the above function can be achieved even if the diameter of the head 14 of the ampoule 13 varies in size, and the ampoule can be used without being limited by the size of the ampoule. That is, when the smallest ampoule is pushed in, the inner diameter of the connecting part (the most narrowed part) between the constricted part 4a and the expanded part 4b is set to a diameter that can hold the head of the ampoule after cutting it. By doing so, when pushing in the head of a larger ampoule, the elastic plate 4 expands from its attachment base,
This allows insertion into the interior of the elastic plate 4, and the head is held by the restoring force of the elastic plate 4 after being cut. The expanded portion 4b formed by a combination of several elastic plates 4 acts to push the elastic plates 4 outward when the diameter of the head of the ampoule becomes large, thereby making it difficult to insert the ampoule. can be done extremely easily.

[Embodiment] An embodiment of the present invention will be described in more detail based on the drawings. FIG. 1 shows a longitudinal cross-sectional side view of the present invention. The inner cylindrical body 3 that has been
A slide shaft 6 which is protruded in a shape having an enlarged portion 4b from the shaft 6 and has a pressing head 5 at its tip is passed through the through hole 2, and a coil spring 7 is inserted and inserted from the rear end of the shaft 6. , a push-in cap 8 is fixed to the rear end of the shaft 6 to be moved in and out of the rear part of the outer cylinder 1, and
By providing a notch 9 at the tip of the holder, a protruding piece 11 is provided horizontally on the tip 10 that remains.

FIG. 2 is a front view showing a state in which the ampoule 13 is inserted, and a clip 12 etc. is provided at a suitable place on the outer cylinder body 1 to make it easy to carry, and a notch provided at the tip of the outer cylinder body An arrow line 15 is attached to the upper part of the ampoule 13 at the appropriate place to serve as a mark when inserting the ampoule 13, and the ampoule 13 is inserted in such a way that the mark 16 attached to the head 14 of the ampoule 13 is aligned with this line.
from the tip notch 9 of the outer cylinder 1,
The ampoule 13 is held by being inserted into several pieces of elastic plates 4 squeezed into the shape of a tea whisk, which protrude from the tip of the inner cylindrical body 3 so as to adjust the size of the head 14 of the ampoule 13.

FIG. 3 is a side view showing the state in which the ampoule 13 is folded, and the protruding piece 11 provided horizontally on the tip 10 of the outer cylinder 1 is opposite to the point scratch 18 previously carved on the neck 17 of the ampoule 13. While applying the neck part 17 on the side and fixing the lower part of the ampoule 13, insert the protruding piece 1
When the upper part of the outer cylinder body 1 is pressed with a fingertip using 1 as a fulcrum, it easily breaks from the point scratch 18, and the broken ampoule 1
The head portion 14 of No. 3 is left in the elastic plate 4 as it is.

FIG. 4 is a vertical side view showing the state in which the head 14 of the ampoule 13 is injected. When the push-in cap 8 is lowered with a fingertip, the coil spring 7 is compressed and the slide shaft 6 is inserted into the through hole of the inner cylinder 3. 2
Penetrate the inside and press down the pressing head 5 at the tip,
It can be ejected directly into the glass fragments processing container from inside the elastic plate 4 without touching it.

[Effects of the invention] The present invention produces the following effects as a result of being configured as in the above embodiment.

The traditional method of cutting glass ampoules by making scratches with a chisel has shifted to the easy-cut method in which fragile areas such as point scratches are prepared in advance at the cutting site, but glass tubes are still cut directly with fingers. I felt a sense of reluctance to do so, and was hesitant to do so, fearing that my fingertips would be damaged by broken glass.
This invention safely and reliably cuts the conventional Easy Cut ampoule at the point of the wound without touching it directly, holds the cut ampoule head as it is, and stores it in a disposal container for glass fragments. This is an extremely practical ampule cutter that can be safely ejected without touching the ampoule with much effort and can achieve the purpose of use regardless of the size of the ampoule head to be cut.
