A venous tourniquet formed in the aforementioned manner is known in the art EN 20 2014 105 480 U1 specified. Usually, such venous tourniquets are sold as individual pieces in a package. The packaging offers advantages for hygiene, but also has drawbacks, such as the handling to open the packaging, additional weight and additional space, which can be of considerable importance especially for such, suitable for single use or certain venous stasis.

Other venous tourniquets of a similar construction are in the US 3,930,506 and the US Pat. No. 3,628,536 shown.

The present invention has for its object to provide a packing unit of the type mentioned above, which offers benefits in use.

This object is achieved with the features of claim 1. It is provided that the package is made of a rigid cardboard or plastic, which surrounds at least one receiving the venous stasis receiving space, that the venous stoppers contained in the receiving space continuously related as a composite and that the packaging in their dimensions on the width and thickness of a Venous stevedore has a matched extraction opening through which the venous tourniquet are individually pulled out to separate them in the region of the extraction opening of the remaining composite.

This construction of the packaging unit with the contiguous venous stems taken up in the receiving space of the packaging offers the advantage of an easily manageable, compact unit in which many venous tourniquets can be accommodated in a small space. The handling of the removal of a venous tourniquet is easy z. B. possible with one hand, since the packaging can be used as a carrier and holder. The individual venous tourniquet is withdrawn from the packaging accommodated in the packaging and separated in the region of the extraction opening, in particular outside the same, after which the next venous tourniquet can be easily pulled out and disconnected if necessary. For example, the user can hold another object with his second hand. In addition, high hygiene requirements are met because the composite is in the packaging with the remaining venous retention, wherein the pull-out can also be designed closable. The venous tourniquet itself and with this the packing unit have very low weight and small space requirement.

Further advantages result from an arrangement of a plurality of packing units, wherein it is provided that a plurality of receiving walls separated by intermediate walls are arranged side by side with vein stacks contained therein as a composite, wherein the vein stoppers accommodated in the separate receiving spaces have different lengths and / or widths.

As a result, different venous stasis for different groups of people, such as children or adults or corpulent persons can be kept in stock and used as needed in a compact unit.

An advantageous embodiment of the packaging unit is that the package is cuboid with two square side walls and four arranged between them rectangular, circumferentially interconnected narrow boundary walls is formed, which form the upper, lower, rear and front end wall and slightly wider than the width of the venous tourniquet are, with the pull-out in the front end wall is introduced. This design of the packaging advantageously also offers the possibility of arranging a plurality of packing units next to one another, as described above. In this case, the intermediate walls are then formed by two adjoining side walls of adjacent packages.

Various embodiments of the packaging unit with vein stoppers arranged therein are that the composite of venous stasis in the receiving space as a roll or in snaking arrangement is housed with several layers lying on each other.

A further advantageous embodiment for use is that the packaging is openable and resealable and for refilling further composites are refillable. In this case, only the composites need to be kept as retrofitted goods and used if necessary.

A further advantageous embodiment for use is that the composite is provided at intervals of the length of a venous tourniquet with Sollrissstellen. The per se stable knitted strip material can be easily torn off in this way, z. B. be weakened by a perforation line or an angled incision.

Another embodiment which is advantageous for easy handling is that, when the second closure part is formed from a material section fastened to the strip material, the predetermined tear point is arranged at a small distance, which is less than one third or one fourth the length between two second closure parts, behind the material section is. As soon as the individual venous jam is pulled out, the predetermined crack point appearing in the pull-out opening is recognized by the hook section being pulled off the loop section with a substantial force component acting in the normal direction (vertical direction).

A further advantageous measure for handling is that a separating aid arranged in the region of the pull-out opening is attached to the packaging.

In this case, various advantageous measures consist in that the separating aid has a cutting edge and / or a clamping edge cooperating with the predetermined rupture point or a hooking element. The cutting edge can z. B. be jagged.

2 the venous stasis after 1A and 1B in plan view, in side view and in a view from below,

3 a packaging unit with a packaging and a composite of venous stems received therein in a perspective view,

4 an arrangement of several juxtaposed packing units after 3 .

5A and 5B Another embodiment of a venous tourniquet in two different perspective views,

6 the venous stasis after 5A and 5B in plan view, in side view and in a view from below,

7A and 7B a further embodiment of the venous tourniquet after 5A and 5B in the non-tensioned state of the pinch-off and in the tensioned state thereof in plan view, side view, bottom view and perspective view and enlarged detail views in the two states and

8A and 8B a further embodiment of a venous tourniquet in the unstressed and in the tensioned state in side view and bottom view.

The 1A and 1B show a first embodiment of a trained as venous tourniquet Abschnürvorrichtung with a pinch 10 for laying at least in part a blood flow in the form of a closed tensioning loop around a body part (eg arm, leg) and in the tensioned state by means of a closure device 30 can be fixed in the form of a hook and loop fastener. The closure device 30 in the form of the hook-and-loop fastener has two locking interlocking parts interlocking, namely a first closure part 300 and a cooperating second closure member 301 on.

In the in the 1A and 1B the embodiment shown is the pinch 10 even as the first closing part 300 the closure device 30 formed while the second closure part 301 as on the pinch tape 10 attached material portion is formed. An advantageous embodiment consists in that the Abschnürband 10 made of a fluffy, with respect to the tensile forces occurring sufficiently tear-resistant or sufficiently high tensile strength having material forming small loops (loops) for the hook and loop fastener, while the second closure part 301 as a short section of flat material with the loops of the first closure part 300 adapted hook elements performs is. The hook having second closure part 301 lies on the first closure part 300 opposite flat side of Abschnürbandes 10 if only one flat side of the pinch-off 10 is provided with loops.

The hook elements preferably have opposite to the tensile force or clamping force of the band section placed around the relevant body part; but they can also be designed as mushroom heads, scale-like elements or the like., Wherein the loops or the loop fabric containing them is / are adapted accordingly. The loops that do not necessarily have to be formed as closed loops and the hook elements can claw into each other in miniaturized training in a variety of fine hairs in the manner of a gecko effect. Advantageously, the loops and / or hook elements of the two closure parts are designed as microelements in such a way that the pinch-off strip 10 feels soft and fluffy even on direct contact with the skin of a part of the body to be cut off.

In studies it has been shown that the trained in the manner described Velcro fastener in the applied state sufficiently high tensile forces (shear forces) parallel to the surface or in the circumferential direction of the Abschnürbandes 10 absorbs the required Abschnürung z. B. of veins to ensure. In this case, a state of stress of Abschnürbandes 10 for generating a pressure of z. B. up to 10 mm Hg or up to 25 mm Hg can be reliably achieved in the area of the veins to stow the blood in the veins. For putting on and taking off, the hook and loop fastener can be easily and quickly closed or opened with a small force component perpendicular to the surface or circumferential direction.

The Z. B. between 1 and 5 cm (preferably between 1.5 and 4 cm) wide Abschnürband 10 can be cut from very thin (less than 1 mm) roll or sheet material and is very flexible with high tear resistance. A significant advantage is the low weight of preferably up to 70 g / mm ² or up to 100 g / m ² or up to 120 g / mm ² . It preferably has a z. B. low inherent elasticity, so that it generates an elastic resilience after applying to the body part itself. Alternatively or additionally, the elastic clamping force can be achieved by an elastic element made of a suitable material 20 be generated as described below with reference to 5A . 5B and 6 will be explained in more detail.

The second closure part 301 has approximately the same or a slightly smaller width than the pinch 10 and preferably a relatively short length z. B. between 1 cm and 5 cm. Alternatively, it may also be over a greater or the entire length of the tourniquet 10 extend. The second closure part 301 is in turn made of thin, flexible material and z. Example, by welding (laser welding, ultrasonic welding or the like.), Gluing, thermoplastic bonding method, sewing or the like. In an end portion of the Abschnürbandes 10 or over the entire or almost entire length of the same attached.

To lock or close the hook and loop fastener, only the other loop portion placed around the body part needs the fastener part 301 to be pressed, with which the closure parts interlock. A further embodiment variant is that loops (or loops) are integrated into one another in the same layer of the nonwoven fabric or loop fabric.

Suitable materials for the Abschnürband or Velcro are viscose, polyester, polypropylene, wherein advantageously spunbond is used in skin-friendly design. The thin but stable material of the pinch-off strap 10 has in addition to the low weight and small footprint and thus also benefits for transport z. B. in a medical bag.

The packaging 50 is made of inherently rigid material, in particular cardboard and / or plastic, and surrounds a receiving space in which the composite 1 the venous tourniquet is received, with a front end of a pull-out 501 the packaging 50 protrudes. In the area of the pull-out opening 501 is a separation aid 502 arranged, by means of which an extracted venous tourniquet behind the relevant second closure part 301 in a simple way from the remaining composite 1 detachable without having to use another tool.

In the embodiment shown, the packaging 50 a cuboidal shape with two square side walls and four peripherally arranged between these boundary walls, which have the same width and length relative to each other and form the upper, lower, rear and front end wall of the package. The width of these end walls or narrow boundary walls is preferably slightly wider than the width of the Abschnürbandes 10 or the composite 1 chosen so that this in the receiving space within the packaging 50 held with little play and is easily guided when pulling out a venous jam and tilting or entanglement is avoided. The composite of the venous tourniquet is executed in the embodiment shown as a role, but may also have a different shape, such. B. a serpentine or meandering arrangement, wherein a plurality of layers of tape sections are arranged one above the other in the receiving space. When trained as a role, this can also be on a roll axis in the package 50 be stored unrolled. But even without an axle results in a good unwindability.

The pull-out opening 501 is adapted to the cross-sectional dimension of the venous tourniquet in thickness and width so that this easily from the pull-out 501 also over the area of the second closure part 301 pull out. The separation aid 502 has a cooperating with the venous tourniquet for cutting to length separating edge, the z. B. is designed as a straight, oblique or serrated cutting edge or Einhakelement. In order to facilitate the separation of the withdrawn venous stoppers from the remaining composite, the composite may correspond to the length of the venous tourniquet with predetermined cracks 102 be provided, for example with a respective perforation line or a z. B. angle-shaped incision, in which the hooking element engages holding to easily tear off the venous tourniquet to the remaining, only weak connection forces forming connection points can. In this way, a user z. B. easily with one hand from the packaging 50 Pull out and separate, so that the handling for removing and then applying the venous tourniquet is very easy. The packaging 50 In turn, it can be received in a holder attached to a work table, a wall or the like, so that the packaging can also be accommodated 50 itself does not have to be held by hand.

The packaging 50 can be designed openable, z. In the area of a sidewall or end wall, and the composite 1 of venous stoppers can be provided as a refill unit to a spent composite 1 to renew, and the packaging 50 to use again.

At the in 4 shown embodiment are several packing units after 3 with their side walls arranged side by side, with the packaging 50 partial packs 50.1 . 50.2 . 50.3 form the overall arrangement or total packing unit. For example, in 3 an arrangement with three part packs 50.1 . 502 . 50.3 each shown a receiving space for a composite 1 of venous stasis hanging in roll form. The partitions between adjacent receiving spaces are through the adjacent side walls 50 educated. It is also conceivable to provide a contiguous package with three receiving spaces that through only a simple partition are separated from each other. As an alternative to a roll shape, the composite can 1 also in this case have a serpentine or meandering shape. Advantageous in this arrangement with several adjacent sub-packages 50.1 . 50.2 . 50.3 is that the total packing unit composites 1 may contain from vascular to composite different venous stasis, such as. B. longer venous tourniquet for larger body parts, venous stasis normal length and venous retention for body parts with a smaller circumference, such. For children. Here are the composites 1 with the different venous stasis z. B. be identified by different colors, as far as they are not easily distinguishable by their different widths.

If the separation aid 502 with its separating edge or hooking slightly offset from the relevant (usually front) end wall of the packaging 50 is located, after separating a venous stoppers, the prominent front portion of the next venous stoppers can be easily grasped and the next venous stasis easily pulled out. The separation aid 502 can z. B. also designed to be foldable. The pull-out opening 501 can z. B. be executed closed with a small flap.

Also in this arrangement with several part packs 50.1 . 50.2 . 50.3 These can be refilled and further different compounds 1 be provided as refill units.

In the in the 5a . 5B and 6 embodiment shown, the venous tourniquet relative to the in the 1A . 1B and 2 embodiment shown additionally a voltage indicator 101 on, with which the clamping force of the pinch-off 10 is recognizable by a user in the range of around a body part tensioning strap. The stress indicator 101 is preferably located in the vicinity of the closure-side band portion, so that in each case it is subject to the tension force exerted by the tensioning loop on the applied body portion. The elastic element 20 is in the range of the stress indicator 101 or outside of it at the tourniquet 10 attached.

6 shows a portion of the tourniquet formed as venous tourniquet with the pinch 10 , a stress indicator 101 with a stretch section 100 and a bridging elastic member and a second closure member 301 Velcro in plan view, side view and bottom view.

In 7A is designed as venous tourniquet pinch in the non-tensioned state of Abschnürbandes 10 in plan view, in side view and in bottom view and with an enlarged section A in the region of the stress indicator 101 shown. In 7B the venous tourniquet is in a taut state of the tourniquet 10 also with an enlarged detail B in the area of the stress indicator 101 reproduced, wherein the Schnschnband 10 in the region of a stretch section 100 in which an elastic element 20 is arranged to stretch a defined path length. Once this defined distance, starting from the untensioned state of Abschnürbandes 10 or a less tensioned state is reached, there is a defined state of stress of the pinch-off 10 in front. The clamping force caused thereby can be achieved by the formation of the expansion section 100 , z. B. by a relevant choice of material (material properties and / or geometric properties, such as length, thickness, width, recesses or the like.) Are set defined during manufacture. In the 7A and 7B is also a usage indicator described in more detail below 40 shown.

In the embodiment shown, the Abschnürband 10 itself off compared to the elastic element 20 be slightly elastic or made of inelastic but flexible material. It can be kept in the production of Abschnürvorrichtung as a roll and according to the desired length of Abschnürbandes 10 be cut to length. Advantageously, a recyclable material, with z. B. natural reinforcing fibers from renewable raw materials and also the other parts, such as closure device, expansion section, fasteners and the like. Can be selected taking into account a good recyclability, as is also possible in the first embodiment. The manufacture, operation and design of the tourniquet device 1 are advantageous interpretable also in terms of a single use only.

The stress indicator 101 is at the in 5A and 5B shown embodiment z. B. as part of a substantially inelastic Abschnürbandes 10 itself formed by being excessively at two spaced in the stretching direction fixing points on the elastic material existing Dehnabschnitt 100 is connected. Between the two fixation points there runs the stress indicator 101 forming pinch tape 10 wrinkle-shaped, wherein the excess length to the desired, defined stress state to be generated also in dependence on the formation of the Dehnabschnitts 100 is tuned. The connection to the fixation is done sufficiently firmly z. As by gluing, welding (laser welding, ultrasonic welding or the like.), Thermoplastic bonding method, sewing or the like .. When clamping the Abschnürbandes 10 the user can reference the more and more the stretch section 100 approaching fold control the stretching process and thus the increasing clamping force and clearly recognize when the two fixing points bridging track portion of the Abschnürbandes 10 has reached its maximum stretch position. At this moment is also the set, defined state of tension or the optimal clamping force of the pinch-off belt produced thereby 10 reached. Should z. B. the venous blood flow in the region of the capillaries in the transition region between the arterioles and venules are prevented, reaches a correspondingly set, defined state of stress of about 10 mm Hg, the person to be treated is little burdened. In the area of veins, the blood flow or the pulsation z. B. by a state of tension of the Abschnürbandes 10 can be achieved according to a pressure of less than 25 mm Hg. For this or other applications can be provided with the above measures suitably trained pinching, the stress indicator 101 and the stretching section 100 are precisely tailored to the particular application.

In a corresponding manner, more than one stress indicator can preferably be attached with differently defined stress states.

In another embodiment of the pinch-off, the pinch-off 10 even be made of elastic material. Is it at in the expansion direction spaced apart fixing points a stress indicator 101 connected with a defined excess length, it consists advantageously of flexible inelastic material, as in the previous embodiment. Will the pinch tape 10 stretched, the folded web section of the stress indicator settles 101 more and more to the outside surface of the Abschnürbandes 10 at. In this case, the excess length of the web section is matched to the bridged portion of the elastic Abschnürbandes, which then the elastic element 20 according to the previous embodiments, in such a way that when fully extending the web portion along the relevant portion of the pinch-off 10 without folding the desired defined state of tension is reached. In this state, then the fixation of the loop by the user by means of Velcro, without tightening the Abschnürband even more.

In the embodiment of the pinch according to 7A and 7B is also a usage indicator 40 present, which in the embodiment shown also the elastic element 20 or at least bridging a longitudinally extending portion thereof.

The usage indicator 40 is formed as in the longitudinal direction or stretching direction extending tear element, which upon elongation of the elastic element 20 With little effort tears before the final elongation is reached, which is present at the defined state of stress. Similar to the tearing element can also be another irreversible element to be damaged, such. As a paint can be attached. The region in which the tear-through element should tear during the stretching process can likewise be prevented by a certain excess length between two fixing points or fastening points of the break-through element on the elastic element 20 be determined, wherein the excess length of the tear element but in any case is less than the excess length of the voltage indicator 101 provided railway section. For example, it can be determined in this way that the tear element already tears when the elongation of the elastic element z. B. about 20%, about 50% or about 80% or another, lower intermediate value has reached relative to the strain present at the defined stress state. Any intermediate values for a tear can be set exactly in this way. Is the tear element of the use indicator 40 torn, this means that the tourniquet device was already in use and thus there is no initial use, as is required in single-use sequestration devices. The tear element can, for. B. consist of a slightly tearing paper strip or strip of fibers and is preferably inelastic, but flexible.

Are the fixation points of the stress indicator 101 and the attachment points of the use indicator 40 In plan view congruent, so both indicators can be easily manufactured in a common step and also matched as a functional unit to each other exactly in the desired manner.

The connection of the for the use indicator 40 used tear element at the respective fixing points or attachment points can be done in a corresponding manner, as in connection with the elastic element 20 described, so for example by gluing, welding (laser welding, ultrasound, printing by means of printing technology or the like.), Sewing or a thermoplastic connection technology or other suitable fastening. In the enlarged view of the section A, a connecting portion (attachment point) is shown, wherein the elastic element 20 on its top at the pinch tape 10 is fixed and is connected on its underside with the relevant attachment portion of the tearing element.

In the 7B is the stretched condition of the pinch tape 10 shown, for example, as it is in the defined state of stress. Here is the tear element of the user indicator 40 already torn by the expansion, wherein the two edges on the crack side are spaced apart from each other by a relatively large expansion gap, ie the tear has already taken place in a correspondingly early stage of the expansion. In the enlarged view of the tear-through area (detail B), the one (shutter-side) remaining portion of the break-away member is the elastic member becoming thinner upon elongation 20 and the stretched track portion of the stress indicator 101 to see.

As 8A and 8B The pinch-off device can also be independent of a tension indicator 101 or offset longitudinally thereof a usage indicator 40 at the pinch tape 10 have, the latter being an elastic element 20 bridged between two fixing points or attachment points with (or alternatively without) excess length, similar to the embodiment according to 7A . 7B described. The pinch tape 10 can be outside the elastic element 20 again be made of inelastic (= inelastic), flexible material or elastic material.
