Description

Ampoule automatic cutting device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to cutting techniques for ampoules (Ampoules), and more particularly to an automatic cutting device for ampoules for automatically wire cutting the neck portion of an ampoule.

Ampoules are small glass bottles for sealing and preserving injections, drugs, etc., which are colorless and transparent and light brown with iron oxide or the like added to reduce the effect of light. Ampoules can be completely sealed without affecting their properties and quality by physical and chemical action in the storage condition of chemicals.

In the ampoule, when the neck portion is cut, a phenomenon in which the decompressed air expands rapidly in the ampoule and fine glass fragments (fragments, particles) are mixed into the injection. When a patient is injected, glass fragments are introduced into the body together with the injection and are not discharged. In particular, patients who are prescribed ampoules for long periods of time are at high risk of exposure to glass fragments.

Meanwhile, a so-called one point cut ampoule having a V-shaped groove in the neck portion is used to prevent the incorporation of glass fragments, but it does not structurally prevent the incorporation of glass fragments. The Korea Food & Drug Administration proposes an alternative to the incorporation of glass fragments when cutting ampoules through the "Guide-line for Safe Use of Injections", and a filter syringe that can filter glass fragments in patients with neonatal or intensive care unit. It was recommended to use. However, filter syringes are reluctant to use in hospitals because they are more expensive than regular syringes. In addition, in the case of a filter syringe, after putting the injection in the filter syringe, there is an inconvenience to use the injection in the general syringe again.

Vials and plastic vials, which can replace ampoules, are more expensive than ampoules and are avoided by pharmaceutical companies. Vitamin C injections, which cannot be used by filling with nitrogen, cannot be used. Of course, the use of ampoules, such as anticancer drugs, anesthetics are the main. The problem of incorporation of glass fragments is constantly being raised, but pharmaceutical companies are denying the incorporation and side effects of glass fragments, while the Ministry of Food and Drug Safety recognizes that glass fragments may be incorporated. Only, what side effects can occur to patients is implied.

Korean Patent No. 10-0701873 "Ampule cutting device" is an ampule cutting portion for inserting and cutting the head of the amplifier, and the air and the collection after inhaling the head and glass fragments generated during the ampoule cutting with air And a collecting unit for collecting the suction sucked through the dust collecting unit, and a collecting unit for separating the dust, a negative pressure generating device for applying negative pressure to the collecting unit. When the user inserts the head of the ampoule into the suction tube of the ampoule, the body is cut to one side and the neck is cut. Glass fragments generated during cutting are minimized by inhalation from the dust collector and injection.

The ampoule cutting device as described above can reduce the mixing of glass fragments, but still does not eliminate the generation and mixing of glass fragments by forcibly cutting the neck portion. Therefore, there is a demand for a cutting device capable of fundamentally eliminating the generation of glass fragments when cutting the ampoules. There is also a need for a cutting device capable of safely and accurately cutting ampoules.

It is an object of the present invention to provide an automatic cutting device for a new ampoule capable of meeting the above requirements.

As shown in FIG. 3, the heating wire 41 is in contact with an outer surface of the neck portion 3, that is, a concave cut portion formed to contact the V-shaped groove 4 so as to cut the neck portion 3 ( 41a). The recessed cutting part 41a is formed in semi-circle shape so that cutting performance of the neck part 3 may be improved. The heating wire 41 may be made of platinum (Platinum, Pt) material. Both ends of the heating wire 41 are connected by the power supply unit 42 and the electric wire 42a. The heating wire 41 may be made into a ring shape or the like for connecting the both ends 41b by the power supply unit 42 and the electric wire 42a. When electric power is applied to the heating wire 41 by the operation of the power supply unit 42, the heating wire 41 is heated to cut the neck portion (3).

Referring again to FIGS. 1 and 2, the linear actuator 43 is connected to the power supply unit 42. The linear actuator 42 translates the heating wire 41 in the direction approached toward the neck portion 3 so that the neck portion 3 is cut by the concave cut portion 41a. The concave cut portion 41a of the heating wire 31 translated by the operation of the linear actuator 42 is in contact with the outer surface of the neck portion 3 to cut the neck portion 3. The wire cutting unit 40 further includes a frame 44 that translates by the operation of the linear actuator 43. The heating wire 41 is mounted above the frame 44.

The automatic cutting device 10 of the ampoule according to the present invention further includes a damping unit 50 for cushioning the shock generated when the neck 3 and the heating wire 41 are contacted. The damping unit 50 is composed of a linear guide 51, a spring element 52, and a stopper 53.

The linear guide 51 slides along the guide rail 51a and the guide rail 51a mounted on the upper surface of the frame 44 along a direction approaching or spaced apart from the rotary table unit 20. It consists of the slide 51b attached so that it may slide, and the carriage 51c attached to the slide 51b. The heating wire 41 is mounted on the upper surface of the carriage 51c. An insulation panel 54 is interposed between the heating wire 41 and the carriage 51c for insulation between the heating wire 41 and the carriage 51c.

The spring element 52 is arranged at the rear of the carriage 51c to elastically bias the carriage 51c toward the ampoule 1 clamped to the spring holder 22a. The spring element 52 is comprised with the compression coil spring 52a which supports the carriage 51c. A support block 52b is mounted behind the upper surface of the frame 44 to support the compression coil spring 52a. In some embodiments, the spring element 52 of the damping unit 50 may consist of a shock absorber, a damping cylinder. The spring element 52 may also be composed of an elastic block made of rubber, silicone rubber, or the like. The stopper 52 is disposed in front of the carriage 51c so as to restrain the position of the carriage 51c approaching toward the ampoule 1. The stopper 52 is fixed to the front of the frame 44.

From now on, the operation | movement with respect to the automatic cutting device of the ampoule which concerns on this invention which has such a structure is demonstrated.

Referring to FIG. 1, the container body 2 of the ampoule 1 is clamped by a spring holder 23a. When the container body 2 is fitted inside the spring holder 23a, the spring holder 23a opens to both sides while elastically deforming, thereby allowing the container body 2 to fit smoothly. When the container body 2 is fully fitted into the spring holder 23a, the spring holder 23a is restored to firmly hold the container body 2.

After the ampoule 1 is clamped to the spring holder 23a, the moving plate 31 approaches the ampoule 1, as shown by arrow "A" in FIG. The neck 3 of the ampoule 1 is fitted inside the spring holder 33a. Thus, each of the container body 2 and the neck portion 3 of the ampoule 1 can be clamped by fitting into the

spring holders

23a and 33a to easily and firmly fix the ampoule 1. After the clamping of the ampoule 1 is completed, when the electric motor 21a is driven and the table 22 is rotated, the ampule 1 is rotated together with the table 22. At this time, the spring holder 33a is rotated by the bearing 32a to smoothly maintain the rotation of the ampoule 1.

Subsequently, when the ampoule 1 is rotated, electric power is supplied to the heating wire 41 by the operation of the power supply unit 42, and the heating wire 41 is heated by heat resistance. As shown by arrow "B" in FIG. 1, the heating wire 41 is translated toward the neck 3 by the operation of the linear actuator 43.

On the other hand, the heating wire 41 is advanced, the impact can be generated as the concave cut portion (41a) in contact with the neck portion (3). At this time, a reaction force is applied to the carriage 51c by the impact force transmitted to the heating wire 41, and the carriage 51c is retracted while the slide 51b slides along the guide rail 51a. As the carriage 51c is retracted, the compression coil spring 52a between the carriage 51c and the support block 52b is compressed to absorb and cushion the impact force. Thus, the concave cut portion 41a of the heating wire 41 is brought into stable contact with the neck portion 3. When the compression coil spring 52a is restored, the carriage 51c is advanced. The carriage 51c to be advanced is caught by the stopper 53 and the position of the carriage 51c approaching toward the ampoule 1 is constrained.

As shown in FIG. 4, the concave cut portion 41a of the heating wire 41 is in contact with the neck portion 3 to cut the neck portion 3. In this way, while the neck portion 3 of the ampoule 1 is cut safely and accurately by wire cutting, generation of glass fragments is prevented. That is, since the cut portion of the neck portion 3 is melted at the time of wire cutting, glass fragments are not generated, so that medical accidents due to the incorporation of glass fragments can be effectively blocked.

As shown in FIG. 2, after the neck portion 3 is cut off, the heating wire 41 is returned away from the ampoule 1 by the operation of the linear actuator 43, and the rotary clamping unit 30 is returned. The moving plate 31 of is raised and returned. The neck portion 3 that has been clamped to the spring holder 33a at the time of the movement of the moving plate 31 is separated from the container body 2. The user can easily use the ampoule 1 by detaching the container body 2 clamped to the spring holder 23a.
