Description

The utility model relates to the field of medicine and medical technology and is aimed at creating a fast and maximally safe process for opening ampoules.

Ampoules are often used, in particular in medicine and chemistry, to store liquid products, such as medicines or aggressive substances, in a sterile manner and protected from diffusion. Conventional ampoules are typically made of glass and have an interior that holds the liquid product and is completely sealed on the outside. Such ampoules usually have an elongated shape and have an ampoule head and an ampoule body, which are connected to each other by a narrow neck of the ampoule. Immediately before using the liquid product, the head of the ampoule is broken off at a predetermined break point so that the liquid product can subsequently be removed from the ampoule.

There are known devices for opening ampoules, which are longitudinal or round plates made of abrasive material or metal, having cutting elements located on the cutting edges of the plates [RU No. 2126769, publ. 02/27/1999; RU No. 35109, publ. 12/27/2003; RU No. 2165054, publ. 01/20/2001].

These designs are inconvenient and traumatic; they lack the possibility of mutual fixation of the ampoule and the device, which does not allow making an even cut in circumference and depth of the glass wall of the ampoule. In this case, when the cut end of the ampoule is broken by hand, the formation of uneven edges of the hole of the ampoule or the formation of sharp fragments that injure the user’s hands is possible.

A device for safe opening of ampoules is known, chosen as a prototype, which consists of a silicone body with stops for fingers, containing a blade on its inner surface, and the ampoule is directed to it through a hole located on the top of the body (RU144246, B67B 7/92, publ. August 20, 2014).

The disadvantage of this device is that it is a soft silicone design and requires mandatory sawing of the ampoule by several turns inside the device, squeezing the ampoule with it to make breaking as easy as possible; after cutting the ampoule, part of it remains in the product and does not allow you to immediately open the next one, squeezing out the remains is required .

The utility model is based on the task of creating a device for the safe opening of ampoules, which allows you to open glass ampoules while minimizing the possibility of cutting yourself on sharp edges formed after breaking the ampoule.

The solution to the problem is ensured by the fact that the device for safe opening of ampoules consists of a body in which a blind groove is made on the front side with additional internal cavities for placing and fixing the neck of ampoules of different sizes, equipped with a limiter side with a pointed edge. Ribs can be made on different faces of the body. A hole can be made in the corner part of the case to accommodate a chain or strap.

The utility model is illustrated in Fig. 1, which shows schematically the internal structure of the product and examples of placement of ampoules of different volumes.

The device is a housing 1 with the ability to place a chain or strap in hole 2. The body has a blind groove 8 on the front side, into which the neck of the ampoule 9 is placed, and a limiter side 6 with a pointed edge 5, which serves as the breaking point of the ampoule 9. On the back side of the body 1 there are ribs 7 that prevent the body from slipping in the hands. Inside body 1 there are cavities for different volumes of ampoules 9, cavity 3 is necessary for fixing large-volume ampoules of 5, 10 and 20 ml, and cavity 4 is necessary for fixing volumes of 1, 2 and 3 ml.

The method for opening ampoules is as follows.

Ampoule 9 is placed with its neck in hole 8 and for ampoules with a volume of 1, 2 and 3 ml it is necessary, resting the neck against recess 4, to make a break in the opposite direction; in Fig. 1 a, b the break goes to the right. In this case, pay attention to the place of the incision, often marked with a dot on ampoule 9, which should coincide in direction with the internal cavity into which the tip of the neck rests. For ampoules of larger volume, it is necessary to place the ampoule in hole 8 and make a break in any of the three directions in Fig. 1c, d, depending on the location of the cut.

A glass ampoule with a pointed spout, which requires a notch when opening, can also be opened in an emergency using this device, even without filing, according to the same principle as 1, 2 and 3 ml ampoules.

Claims (2)

1. A device for safe opening of ampoules, consisting of a body in which a blind groove is made on the front side with additional internal cavities for placing and fixing the neck of ampoules of different sizes, equipped with a limiting edge with a pointed edge, while ribs are made on the edges of the body. 2. The device according to claim 1, characterized in that in the corner part of the body there is a hole with the possibility of placing a chain or strap in it.
