Description

[Detailed description of the invention] Medical ampoule safety opening device For medical ampoules whose contents are used for intramuscular or intravenous injection, a small auxiliary Although tools have already been proposed, today it is still difficult to make cuts with a saw cutter. Even ampules that have grooves cut into them at the site can cause injury. in this way , cutting and folding operations are not clear, so glass of harmful size may be removed. The debris entered the inside of the angle.

The purpose of the present invention is to greatly simplify these complicated operations and to In order to make the operation of cutting the ampoule head at the neck and breaking the ampule without danger. and speed up the operation, especially to avoid the dangers to the patient mentioned above. The goal is to prevent danger.

In particular, the medical ampoule of the present invention is capable of dividing the neck of an ampoule made of glass. Gulu's safety release device features a resilient forced guide for the ampoule neck and , a contact spring located in the area of the forced guideway and connected to the microswitch, and a driveable Combined with a powerful cutter grate and a knock-off ram in the area of the tar plate. and another micro switch contact member, thereby The following objectives will be achieved.

Such a configuration greatly simplifies manual or automated operation. , for example lIn! ! Cut ampoules of all customary sizes from 50 to 50. At the same time, it is possible to clearly cut costs that were previously required in less time. can. The device can be assembled on a small board, and the board It is made movable by Also, supports the cutter plate or motor so that it can swing. It is desirable to do so.

In a preferred embodiment, the locking recess formed in the work plate is in the area of the knock-off ram member in a manner extending from the recess for the knock-off ram member. It is provided. When introducing the ampoule along the forced guide, the first micro- The contact spring of the switch is operated and immediately connects a small electric motor with fast starting speed. The machine rotates the cutter plate. At this time, while moving the ampoule forward by hand, I won't cut it off. When the ampoule is cut and fed further, the hollow part of the disc cutter It locks in the locking recess. A micro switch is activated here via a contact spring. , the knock-down rams arranged opposite to each other are moved forward by the excitation of the actuating electromagnet.

The head of the angle is clearly folded, and the folded head is It is demoted to a containment container.

Then, the device is prepared for the next process of cutting and folding ib operations. or, The device may be fixed or heavy so that only one hand is required for operation. It is easy to configure it so that it does not exist. This way, the doctor can see the other hand. From there, the syringe can be ready.

It is possible to provide a running passage Af between the two rails. Here, power, One rail or spring steel wire is split approximately in the middle to accommodate the turret.

The contact is activated when the force passes through the tar, and the point follows the previous direction. At this point the actuating electromagnet is advanced and breaks the neck of the ampoule.

The ampoule can also be brought into contact with the arm of the arm.

At Step 9, a predetermined function (cutting or folding) is activated. operating plan The jar returns to its original position due to the reversal.

Additionally, the device can be powered by storage batteries, batteries, or via power lines. can.

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Figure 1 of the drawing is concrete A perspective view of the embodiment shown in FIG. It is a figure showing a position.

On the working plate shown schematically in Figure 1, an electric motor 1 is mounted via an unnumbered stand. It is supported so that it can pivot in place. A force is applied to the electric motor 2, and the tar plate 5 is fixed. There is. Cargo random or diamond covered cutter plate. Ma An actuating electromagnet 3 with a freely advancing knock-off ram 4 is mounted in the area of the working plate. It is. The head of the knock-off ram can be provided with a rubber coating. The work board The cavity is provided with a number for the force and tar plate 5. It continues into a circular hole. This void expands in the area of the knockdown ram 40 passage. This forms a notch 9 for locking the angle neck. Area of cutout of work plate For example, a forced guide in the form of a parallel spring steel wire 8 having a thickness of 3 m is provided. child A micro contact switch and a contact spring 11 protrude from the forced guide, not shown. Connect or disconnect the cutter grate motor via the feed line. slight web A stop separated from the parallel guide by a further contact member, for example a second The contact spring of the micro-contact switch 6' extends out.

The role of the switch and chiro' is to knock down the actuating electromagnet via a supply tMA (not shown). The purpose is to operate the ram.

A spring, not shown, is used for returning the actuating ram.

A container 7 for storing the ampoule head or ampoule neck is provided under the work plate. There is.

power, the area around the tarplate is sensitive to heat radiation and/or moisture release from the human body. A corresponding sensor section can be provided. Inadvertently, for example, the operator's fingers may If you accidentally enter the area, the sensor section will be automatically shut off.

In the drawing, 10 is a steel wire for spring support of the electric range and for limiting rotation. For example, if the device is to be fixed to a wall, it must be locked in a J-type attachment and removed. An adapter may be provided for attachment in the form of a bottle that is unlocked upon removal.

The measures according to the invention also apply to ampoules used in the cosmetics industry, e.g. It can also be used in large beauty salons. It is also particularly applicable in the field of veterinary medicine. obtain.

In Figure 2, a movable armature with a thin rod is attached to the stator of the electromagnet or is supported by the coil. The ram configured as a hollow cylinder has a thin rod above it. attached to the free end of the When a current is sent to the electromagnetic coil, the movable armature A current is induced in the ram, which causes the movable armature to connect with the rod and ram. be driven forward quickly. The movable armature comes into contact with the coil and suddenly stops. After that, the hollow cylinder placed on the rod is compressed due to its own weight or inertia ( The counterbalance spring flies slightly forward against the spring force of the (remove the breakage of the angle neck where the angle was inserted). In this case, especially when the balance spring is It buffers the impact effect, so it can be used against the head of extra-thick and extra-thin medical ampoules. there is no problem. Then the compression spring returns the hollow cylinder and after the magnetic field is interrupted, the electromagnetic A tension spring attached to the other side of the coil pulls the movable armature back to its original position. .

In Figure 2, A indicates the rest state, B indicates the intermediate state, and C indicates the maximum motion or working state. Show.

In FIG. 2, the ram device as a whole has a narrow opening in the hole of the electromagnetic coil 101. A movable armature 101 having a movable armature 101 is inserted. Mouth and C are also (on the right side of the diagram) ) is passed through a hollow cylinder 103 arranged in Compressed into the hole of the hollow cylinder 103 A spring 4 is supported and fixed to a thin rod by a screw 5. cylindrical on rod To limit the travel in the direction of the movable armature or electromagnetic coil (at rest position) (at the end) The movable armachia side end has a monthly installment pin that penetrates through the narrow opening. .

The other side of the movable armature (in the drawing) is used to pull back the electromagnetic device after activation. A tension spring 6 is provided on the left side) and the stopper is passed across the movable armature. The outer end of the tension spring 6 is held by a split pin 8.

Diagram B shows that when current flows, the electromagnet rapidly attracts movable armature 1a1 in the direction of the arrow. It shows you what to do. This action causes the ram 3 to move outwards.

The direction of movement of the ram is indicated by an unnumbered arrow.

In diagram C, the rod 1 of the movable armature has already been extended to its maximum extent. B The hollow cylinder placed in the head is designed to prevent sudden stoppage of the movable armature 1 (hitting the coil). After contact], due to its own weight or inertia, a compression rebound occurs as shown by the smaller arrow. Resisting the spring force in Step 4, fly the ampoule a little further outward, and break off the cut end of the ampoule. Take it. In this way, the compression spring 4 mentioned above simplifies the stroke of the working ram. I was able to extend it.

The compression spring 4 then causes the hollow cylinder 3 to return again. After the magnetic force stops, the tension spring 6 pulls the movable armature 1 back to its original position (FIG. 1).

A particular advantage of the measure according to the invention is that, on the one hand, no mechanical cams etc. are provided; I can think of something.

On the other hand, because of the "elastic" ram, there is no need to worry about shattering the head of the cyan puller, and rather the force is reduced. Emphasizes that the ampoule is regulated and is rapidly transmitted to the head of the ampoule, which must be removed at the same time. Must.

By extending the stroke of the ram, even extremely thin angle heads can be broken. Can be done.

According to FIG. 2, the provision of spring wires is no longer a prerequisite. cutter pre The cart turns to the left.

To compensate for the thickness, the electric motor also turns to the left in the drawing. When you lead it backwards, it will charge Micro to the right. The itinerary has been artificially extended and forced. Since it can protrude beyond the guide, a kind of post-acceleration occurs.
