Description

The invention relates to medical technology and is a device for opening glass ampoules.

The most commonly used in medicine are glass ampoules, the head of which, before injection, is removed by a fracture along the neck. For this, before a break in the neck of the ampoule, an incision is usually made with a special glass cutter. However, there is a real danger of cutting the operator’s hands and breaking the ampoule, which in some cases can lead to serious consequences.

To facilitate the removal of the head during the manufacturing process, a micro-cut is performed on the neck of the ampoule or by special heat treatment to form internal stresses in the glass at the fracture point. However, in this case, there remains the possibility of injury to the operator and the destruction of the ampoule with technological deviations that are difficult to control. In addition, such ampoules are prone to spontaneous destruction during careless handling of them.

A device for opening ampoules is known, comprising a housing with an opening for inserting the head of the ampoule and a device for separating the head by fracture at the place of a previously made micro-cut on the neck of the ampoule (Russian patent No. 2011375, IPC A 61J 1/06, 1990), the closest to the technical essence and the set of essential features of this invention is similar. When using this device, the injury of the operator is practically excluded, however, the fracture of the head and the ingress of glass particles into the ampoule are possible if broken. In addition, the sterility of the contents of the ampoule may be impaired due to the rather long contact of the opened ampoule with the non-disinfected device case. Finally, such a device is applicable for opening only those ampoules in which the neck is previously weakened either by micro-incision or by other means, i.e. it does not apply to most ampoules manufactured by the medical industry.

In the present invention, these drawbacks are eliminated by the fact that in the device for opening ampoules, comprising a housing with an opening for inserting the head of the ampoule and a device for separating the head by fracture along the neck of the ampoule, the device for separating the head is designed as a cutter installed in the cavity of the case, the device is equipped with a capillary structure impregnated with a colored disinfectant composition, the head of the structure covers a glass cutter, and on the wall of the body cavity against the glass cutter is made, At least, there is one recess for the stop of the ampoule head, the device is equipped with an opening in the housing grooves with a sliding cover and an elastic pusher, and a piston installed in the housing cavity, with one end of the pusher connected to the cover and the other to the piston.

FIG. 1 shows a longitudinal section of a device for opening panampul ampoules in an inactive position;

in fig. 2- the same in the working position at the opening of the ampoule;

in fig. 3 shows the cross-section of the device along A-A.

The device for opening ampoules of Panampul comprises a body 1 made of rigid plastic. At the end of the housing 1 there is a hole 2 for inserting the head of the ampoule. The device for separating the head is made in the form of a glass cutter 4 made of diamond or hard alloy installed in the cavity 3 of the housing 1 at the edge of the window 2. The device is equipped with a capillary structure (felt-tip pen) 5 impregnated with a colored disinfectant composition, the head of the structure 5 enclosing the glass-cutter 4. On the wall of the cavity 3 of the housing 1 against the glass-cutter 4, at least one recess 6 is made for the stop of the ampoule head.

In the slots 7 of the housing 1, the cover 8 of the hole 2 and the elastic pusher 9, which is made, for example, from a sheet of flexible plastic, are slidably mounted. In the cavity 3 of the housing installed piston 1 0 connected to one of the ends of the pusher 9, for example, bracket 11. The other end of the pusher is connected to the cover 8.

The housing 1 is provided with a clip similar to a pen clip (not shown in the drawings), with which it can be fixed in an operator’s pocket.

The device works as follows.

In the off position, the hole 2 is closed by a lid 8 (Fig. 1). When preparing the device for operation, it is taken in the hand by sliding the cover 8 with the thumb and opening the opening 2 (Fig. 2). When this piston 1 0 moves the pusher 9, sliding in the slots 7 in the middle of the cavity 3. The ampoule is inserted into the cavity of the head 3 until it stops at the recess 6 (the head of the ampoule is shown in Fig. 2 by a dotted line). After that, turn the ampoule and device in opposite directions by 360 degrees. In this case, the glass cutter 4 makes an annular incision on the neck of the ampoule, and the capillary structure 5 causes a strip of colored disinfectant to be applied to the incision. The paint is judged on the presence of such a composition in the capillary structure 5 and the reliability of applying this composition to the notch area. Then they break the head of the ampoule, separating it along the notch, and use the ampoule for its intended purpose, for example, for injection. Due to the presence of a disinfectant composition on the surface of the ampoule in the incision area, the sterility of the contents of the ampoule is preserved.

The device can sequentially open several ampoules, the heads of which accumulate in the cavity 3 of the housing 1. Then these heads can be removed by sliding the cover 8 back to the stop. When this piston 10 moves in the cavity 3 directly to the hole 2, pushing the contents of the cavity through the hole 2.

After use, the cover 8 is moved forward, closing the opening 2, to avoid contamination of the cavity 3 and the drying of the structure

five.

Thus, this device ensures complete safety of the operator and preservation of the sterility of the contents of the ampoule during the opening process.
