Description

DETAILED DESCRIPTION OF THE INVENTION Field of application of the Invention Vη11 This invention relates to an instrument for cutting the neck of a container, and more specifically, to a device for cutting off the neck of a container, and more specifically, to secure the safety of both the contents of the container and the operator, and to cut off the neck of a drug or its contents. This invention relates to a container cutting/opening device for quickly and easily cutting the neck of a storage container.

BACKGROUND OF THE INVENTION Various drugs are often sold in small containers such as ampoules (or tubular containers) in order to be stored in a completely sterile environment and without contact with air.

When visiting a hospital or making a home visit, it is often necessary to open several, and sometimes a large number, of medicine bottles. These containers, such as ampoules, are used to store the genuine drug and a solvent, such as distilled water, and the contents of one container are used to dissolve the freeze-dried or crystallized product stored in the other container. These containers are cut open when transferring the solvent. Also, in home care, it often occurs that ampules of medicine MK have to be opened, especially in order to administer the medicine intravenously, intramuscularly or via the orifice.

It is generally known to cut open tubular containers such as ampoules with a suitable small metal saw or instrument having a Kenreki blade or the like, which instrument cuts the neck of the container and cuts the glass. The drag force is reduced and in this way the neck of the container can be broken. This cutting method is very rough and has low precision;
It was very cumbersome and difficult to maneuver the cutting instrument around the entire circumference of the neck of the container. Therefore, inexperienced operators sometimes act quickly and make a single incision in the glass of the container, and then break the glass with both hands to separate the neck of the container. The cutting operation performed in this manner is incomplete, not gaping, and jagged around the neck. Additionally, there is a risk that small glass fragments may enter the container, contaminating the drug, and injecting the patient with the drug, rendering the contents of the container unusable. Sometimes things happen.

It was not uncommon for a male nurse or doctor to be accidentally injured when attempting to break the neck of the container with his hands to open it. The experience of the operator, his calmness during operation, the conditions of use of the saw or other cutting tool, the quality of the glass and other less important requirements contribute to all the above-mentioned factors.

The device of the present invention seeks to eliminate all the disadvantages associated with the prior art mentioned above and to achieve various objects as follows.

a) Realization of a container cutting tool that quickly and easily cuts the entire circumference of the neck of the container.

1) Realization of a container cutting tool that does not require the operator to be skilled or touch the neck of the container.

C) Realization of a container cutting device that eliminates the risk of injury to the operator and contamination of the product, ensuring maximum safety and hygiene.

d) Implementation of a container cutting instrument that allows the container to move relative to the instrument, which is preferably held stationary, thereby making 1) the cutting 1fI↑ operation independent of the operator's experience.

These and other objects consist of a longitudinally extending hollow body having a substantially C-shaped cross-section;
fi, and a longitudinally extending hollow portion is provided in the interior of the hollow body that is open at both ends thereof along a gutter defined by two longitudinally extending edge portions facing outward. , the hollow body is installed in the head of the tubular container and is deformable so that the cross section of the hollow body changes by manually operating the outer surface thereof, and one end of the hollow body A container that is safe for cutting and opening the container, the container being configured such that at least one cutting member extends inwardly from the hollow portion of the tubular container to inscribe a surface portion corresponding to the neck portion of the tubular container. This is accomplished with a cutting release instrument.
