Abstract

The proposed improvements relate to the handling of an apparatus combination (1, 2, 18) which can be used to perform important operations for withdrawal of blood and injection in an extremely simple manner with only one unit. This innovation relates to the following functions: opening of the ampoules with a simple cut-off device (7, 16), loosening and pulling off the cannulas on a cannula release mechanism with partial wall weakening (4, 17), sliding-off of the waste over a funnel-shaped rolling device (3, 12) directly into an exchangeable collecting vessel (1) which can be tightly sealed with a special closure (21). The collecting vessel comprises an exchangeable, impregnated folding box which is taken out after filling and is tightly sealed with a special closure, and thereafter is disposed off together with its contents in a hygienic manner as medical waste. Without the recesses in the upper part (2), this apparatus combination - produced in a large format - can also be used for the destruction of fairly large amounts of waste as result in hospital practice. <IMAGE>

In Fig. 1 above is the mode of operation of a novel folding device shown. This principle does not require any additional folding bars! Because the The leverage required for edging the sawn ampoule neck is achieved without any aids solely through the shape and arrangement of the recesses 6, 6a and 7, as well as through the combination of inclined planes 16 arranged in opposite directions is achieved, which, according to their course to the wall profile, result in two acute-angled edges, which in their function as a guide strip F and breaking edge B when using a wedge-shaped wall so far apart that a sufficiently large lever arm which enables large and long-necked ampoules to be abruptly bevelled.

The recess 7 is arranged at an acute angle to the upper edge of the device. Their shape is oval or conical. Both cut surfaces preferably form in cross section an inwardly rising parallelogram 16, the inner edges of which are higher than the outer edges, and in such a way that the inner edges converging below the The rounding of the recess 7 preferably widen somewhat conically. The two shifted Acute-angled edges of these cut surfaces then take on the function of a guide bar (F) and breaking edge (B). The oval or conical recess 7 narrows towards the lower curve, the surfaces of the parallelogram. At the same time narrowed the opposing plane with the rising breaking edge, whereby two opposing, scissor-like cut edges are created! Now the glass ampoule - as shown - Quickly inserted into the constriction along the upper outer edge (leading edge F), so the breaking edge B rising on the inside of the wall presses the ampoule head like a lever upwards, whereby the ampoule neck is beveled on the filed underside, respectively. is sheared off. The edging takes place almost suddenly, without the sawn-off one To have to rotate the ampoule axially (!) And without the need for an additional lever movement to be carried out by hand.

If the wall of the upper part 2 is funnel-shaped and conical in profile resp. wedge-shaped, the leverage increases analogously to the side Distance between the offset edges (Fund B). which inevitably results from the wedge shape and by the parallelogram-like arranged cut surfaces of FIG. - The angled cut surfaces 16 of the recess 7 as well as the funnel shape of the container opening at the same time favor a largely vertical position of the ampoule to the outer wall, which makes filing and edging easier.

Together with this principle, there are further advantages: that the recess 6 is not horizontal (as shown in the main application), but runs slightly downwards, where it goes directly into the lower wall surface of the recess 7 passes! - With this arrangement, namely the sawn-off ampoule without transferring it directly from the sloping ampoule file away in the same direction directly into the recess 7. aside from that the V-shaped recess 7 can be as extensive within the wedge-shaped wall Obtained inclined position that the cut surfaces 16 formed on their open side stand vertically one above the other in approximately one plane, from where they begin - narrow - diverge with offset edges to form a parallelogram.

The two side edges of the recess 6 are preferably along the ampoule file and the holder 6a beveled. Thus the line in direct extension of the saw edge within the recess 7 an imaginary central axis. On the other hand, since the filed crack runs in the middle of the fillet of the glass ampoule, this line is identical to the imaginary central axis, so that when retracting quickly A certain leading edge of the sawn ampoule is no longer to be observed.

If the recess 6 with its holder 6a is lowered so far that the saw edge of the inserted ampoule file in height and course with the rear "Breaking edge B" matches, an almost smooth transition into the recess is created 7th

The middle figure in Fig. 1 shows the arrangement of the ampoule opener in side view with an oval recess 7, 16. In cross section C-D (Fig. 1 below) is the greater distance between the two offset due to the wedge-shaped wall Edges "F- B" can be seen. It can also be seen how the two planes of the oblique Adapt the recess to the profile of the neck of the ampoule, which also changes in handling proves to be very advantageous (see also the diagram above).

Another notable advantage results from the use a particularly durable and relatively long hard metal file. This is the length to adapt the recess 6, 6a accordingly, so that to achieve a sufficient With a deep saw cut, it is not necessary to move the glass ampoule back and forth several times; this in particular when the upper part 2 (separated from the collecting container 1) is repeated and permanent use is intended, ~ The recess 4 for loosening stuck Injection cannulae has a wall weakening 17, the width of which corresponds to the outer diameter adapted to the standardized cone and wedge-shaped in cross section. the Wedge shape starts at the top with a relatively narrow wall thickness, which is the minimum possible distance corresponds between the syringe base and the attached cannula cone. Through this there is the possibility of the container wall on the whole device evenly and arbitrarily to train strongly. Associated with this is the further advantage that the angular recess 5 can be shaped out of the normal wall strong enough.

The shown in the lower cross section of FIG. 1, divided longitudinally and the very thin-walled unwinding device 3 is in the manner of a trap towards the middle funnel-shaped. This trap is particularly elastic and lies directly below the recess 4. The detached in this recess 4 from the syringe cone Cannulas then fall directly into this funnel-shaped deformation of 3 and from there through the narrow slot on the underside into the collecting container below. Through the bead resp. Material weakening 12 becomes the flexibility of this deformation further improved, with the advantage that the injection cannulas -by the height of fall conditional - even easier for Saturday container can fall through! The previously described recess 4 with its material weakening 17 is shown in FIG. 2 again clearly shown; also the angular formation 5 with a wall thickness, which corresponds to the normal wall.

Fig. 3 shows the cross section through the upper part 2 with one half the longitudinally divided and previously described unwinding device 3 together with one spring-loaded counterpart in the form of an unwinding device 8, which is preferably over the axle mounting from above and / or from the side by means of a simple Lever can be tilted and then springs back to its original position. Analogous to the Arrangement in Fig. 1 below is this combination 3, 12, 8 and funnel-shaped formed with a slot-like opening, but such that the lever arm of Part 8 is intentionally shorter than its counterpart 3:12.

In Fig. 3, the recess 7 is also obliquely downward extending cut surfaces 16 formed, but such that the lower outer edge the function is designed as a leading edge and the upper inner edge is designed as a breaking edge B. is. In this example, however, the break line must point upwards so that the glass ampoule would have to be rotated around 1800 after sawing.

Fig. 4 shows an upper part 2, which with an open sleeve 18 is combined. In the upper partial section, this combination 2, 18 consists of one Piece. The sleeve 18 is open on the narrow sides, so that a suitable collecting container 1 can be inserted from both sides and placed on the narrow-rimmed floor can. Since the narrow sides of the upper part 2 are closed up to the edge 20, is the rectangular opening of the inserted container is fixed in its shape in such a way that that the inner stop edges of the upper part 2 cover the container edge sufficiently. The inner walls above these stop edges can be used to better cover the The container opening is preferably tapered. - To remove the filled The container has lateral recesses 19 on the open end edges of the sleeve 18 arranged. In addition, at least one narrow or broad side of the sleeve should 18 must be open to insert the container.

In the lower cross section of FIG. 4, the wall is on the narrow sides the sleeve 18, which is open at the bottom, is cut open from below to the edge 20. The two open legs of the broad sides are flexible and form in this form a spring clip with a double notch on the inside and outside of the lower edge 23 is arranged, the inner detent is used to support the inserted from below Collecting container 1.

When inserting the device combination 1, 2, 18 into a stand 10 the outer edge of the double notch 23 engages within a recess in the base and forms with this an ideal free-standing device with a good snug fit. The filled one Collection container 1 can only be removed from this free-standing device if the Stand 10 was previously pushed up over the edge 20.

In Fig. 5, a collecting container 1 is in the upper figure as a simple folding box shown in the manner of a conventional pharmaceutical packaging. When inserting this folding box, the lid and side flaps are turned over to the outside and fixed within the sleeve 18. The filled carton is removed and sealed in a known manner and including the filling as medical waste destroyed. (See also the description in the main application to Fig. 4 Page 6 from line 22 and page 7 to line 21.) The collecting container below is as formed an impregnated folding box. The innovation, however, is that the container 1 by means of a hinged lid and overlapping side flaps of is closed on the outside. For this purpose, an adhesive bond with two Components proposed in such a way that bonding is only possible if both Components are placed on top of one another or pressed onto one another; i.e. one component by itself neither with paper or cardboard, nor with plastic or metal or. Like. Is to be connected.

To .B. a folding box 1 made of cardboard or cardboard by means of To be able to seal such an adhesive seal tightly, there are three side surfaces the container opening - as sketched in Fig. 5 below - with one of the two components 21 provided; the insides of the three side flaps, which are preferably hinged to the hinged cover on the other hand with the other component. Both components preferably exist from a special adhesive with a surface, which e.g. a bond prevented with paper, cardboard, plastic or metal; but in connection with both Components bond together perfectly! (In the mode of action like self-adhesive envelopes.) During the manufacturing process and during transport However, it should be noted that those coated with the special substance of both components Parts of the container 1 do not coincide with one another. Be for this purpose the hinges hinged on the hinged lid (and the hinge point of the flap itself) each provided with a double fold and after applying the special adhesive (immediately after cutting) turned back by 1800 and on the underside of the lid - or Upper side - easily detachably fixed by spot welding or the like. The bottom part will treated in the same way. The usual way of gluing the long sides together to form the folding box is then expediently done with the same adhesives. ~ Should the adhesive are attached to only one part of the surface, instead of a two-component adhesive a normal glue used. After being applied to only one side surface this adhesive covered by means of a waxy film, in such a way that this film can be easily peeled off before gluing the parts together: either in the Art a self-adhesive label or by means of a double-sided adhesive tape. - The better solution is seen in the fact that the adhesive, including the cover sheet, is made during manufacture the folding box are applied, preferably in the arrangement as shown in FIG. 6.

This blank with the strip-wise arrangement of the adhesive plus Foil - above and below on the three side surfaces hinged next to each other - allow It is about applying the cover film in one piece and pulling it off again in one go! The tabs on the two narrow sides of the hinged cover can be on their front edges Get two folded appendages after gluing the flaps around the edges of the container are placed and thus result in an absolutely secure closure all around.

In Fig. 7 the hinged lid of the collecting container 1 is on the rear wall hinged and folded again parallel to this at a small distance, so that the cover when pressed into the container opening at this fold again angled and against the back wall pressed will. The ones on the three open edges of the lid 22 arranged lugs then snap into the recesses when the cover is pushed in further resp. Slits 11, whereby a snug closure is obtained without excessive bending the container wall cannot be opened again.

The locking with the slots 11 on the three side surfaces of the container 1 can also be replaced by side tabs that are hinged to the edge of the container are. The slots 11 are then attached directly to the tabs, which be bent inwards during the closing process so that the three lugs of the pressed in Anchor the cap in it. The tabs themselves have a lateral deformation and interlock with each other, so that an optimal closure without any sticking is achievable! ~ The tabs on the two narrow sides of the container 1 can take place of the slots 11 are provided with incisions or notches, which for the two lateral lugs of the closure cover serve as a stop, so that at the same time the lateral Clearance between the lid and the inner wall of the container closed, respectively. is covered.

(See also claim 18 of the main application on page 5 of There protection claims.) In this way, the collecting container shown in Fig. 7 is 1 can also be produced as a folding box, in such a way that the bottom part - as shown in FIG. 5 u. 6 described - is formed.

In Fig. 8, a complete device combination is shown in three dimensions pictured. This arrangement is particularly suitable for wall mounting. The sleeve 18 is made in this example practically only from the rear wall with the angled floor and in this way is very simply made of plastic or of a stainless steel sheet can be produced and releasably fastened within the upper part 2.

The upper part 2 has the already described functional elements 3, 4, 5, 6, 7 with the improvements of this registration. The collecting container 1 consists of one impregnated folding cardboard in the manner as described for Fig. 5 and 6 and is of pushed forward into the lower opening of the upper part 2, such that the container 1 sits resiliently on the angled bottom part of the sleeve 18 and thereby counteracts the stop in the interior of the upper part 2 is pressed. The rear wall 18 can be on both Side edges with an additional side stop, e.g. in the form of tabs be provided.

When inserting the collecting container 1, the hinged lid with its Side flaps folded backwards. This means that these parts are inside the upper part 2 between the rear wall 18 and the outer wall of the container. - The filled container 1 is taken out, closed as described and then as a medical one Waste destroyed.

The improvements proposed in the present application result in a device combination, with which different, very important work processes be combined in an optimal way, so that the device can be used in clinics and doctors' offices is an indispensable tool. -The combination shown in Fig. 8 with Upper part 2, tilting device 3 and sleeve 18 with collecting container 1 (but without the Recesses 4, 5, 6, 7) is also suitable in large format for hygienic disposal larger amounts of waste, such as those generated especially in larger clinics.

The bulk packs required for this purpose can namely very beneficial after the same Principle and with the adhesive and proposed for this Locking system can be established.
