Description

The invention relates to a multi-purpose clamp for jamming with or on various objects and / or objects, in particular for use in emergency medical field, for example as a holder for infusion bottles, infusion bags and / or rinsing bags (each up to 5000 ml capacity), as an opener and / or closing of connecting tubes and / or as a holder for compression bandages.

The multi-purpose clamp comprises a first clamp arm having a first distal clamp end and a first proximal handle end, the first clamp end having a first jaw and the first handle end being tangible with at least one finger and / or thumb. The multipurpose clamp further comprises a second clamp arm having a second distal clamp end and a second proximal handle end, the second clamp end having a second jaw and the second handle end being tangible with at least one finger and / or thumb. The first clamping arm and the second clamping arm are rotatably connected to one another in a crossover region. In particular, the first and the second end of the handle each have a handle eye, so that the clamp in the manner of a pair of scissors is tangible and openable or closable. Furthermore, the multi-purpose clamp on a latching device for adjustable locking of the first clamp arm with the second clamp arm, whereby various objects and / or objects between the jaws can be clamped. The latching device allows the locking of the clamping arms in different clamping positions.

Clamps of the type described above are known especially from the medical field. So-called surgical clamps are used for various tasks in surgery and are specially designed for their respective purpose. For example, arterial clamps serve to hold and grasp blood vessels and for this purpose have mostly straight or slightly curved, recessed mouth surfaces, whereas towel clamps are designed to fix drapes. From the DE 200 22 012 U1 is a medical clamp for grasping tissue known. The clamp arms are bent and have at their ends jaws, with which the tissue is gripped. In a, opposite the distal end of the clamp area a latching device is arranged. The latching device comprises two toothed extensions, which extend from one clamping arm in each case in the direction of the adjacent clamping arm and are designed for mutual engagement. The clamp can be locked in this way in fully closed or partially open position.

A use of such terminals is also known from other applications. For example, a rescue clamp intended for emergency use is from Meier-Medizintechnik ( http://www.meiermedizintechnik.de/hersteller/meiermed/meiermed-rettungsklemme.html; 15/10/2015 ) available. In this rescue clamp one of the handle eyes is open, so that the handle eye can be used as a hook, especially for hanging infusions. A disadvantage in terms of use in emergency operations is the relatively high weight of the stainless steel rescue clamp. In addition, the clamp has a tapered distal end, which may, for example, damage the clothing of a paramedic when transporting the clamp within a trouser pocket.

A designed as a hose clamp design made of glass fiber reinforced plastic is at VMP GmbH ( httQ: //www.akutdialyse.de/klemmen.html; 15/10/2015 ) available. By means of a handle-side pliers function, the hose clamp is suitable for opening screwed hose connections, as can be found, for example, in PEG transfer systems. The edged clamping jaws (clamping by edge to edge) are particularly suitable for clamping hoses. The US 3,786,815 In contrast, discloses a cloth clamp, which is made by injection molding of glass fiber reinforced nylon. At the distal end of the clamp arms is in each case a clamping surface in an oval design (clamping by surface on surface). The clamping surfaces are suitable for grasping flat objects of different thicknesses. A locking device has toothed locking fingers, with multiple teeth, so that the clamping arms can be locked with varying clamping strength. However, both mentioned clamps have no possibility of suspending objects, in particular infusions.

Object of the present invention is to avoid the disadvantages mentioned and to improve terminals of the type described above, in particular with regard to their scope of functions.

A multi-purpose clamp according to the invention is characterized in that the first clamp arm and / or the second clamp arm has at least one additional handle extension at the first and / or second handle end, wherein the at least one handle extension is suitable for suspending various objects and / or objects. In particular, the Grifferweiterung by additional material is integral with the clamp trained or executed as an additional component that otherwise connected to the terminal. The Grifferweiterung extends starting from the handle end of the multi-purpose clamp and is not part of the actual handle or the handle eyes.

In an advantageous embodiment, the at least one grip enlargement is formed proximal to the respective grip end, in particular the respective grip eye, or extends in the proximal direction starting from the respective grip end. Although the formation in the form of a hook is advantageous, it is conceivable to form the handle extension with another shape, such as a knob, an eyelet, etc. In particular, the opening of a hook-shaped handle extension to the outside or in a, the adjacent clamping arm opposite direction.

It is also advantageous that the at least one Grifferweiterung comprises a spring pin and / or is formed with a locking nose. Especially in connection with a design as a hook can be formed by means of a spring pin an openable eyelet. In particular, the spring pin for hooking the object to be suspended and / or object into the interior of the eyelet elastically deflect and returns due to its elasticity in the starting position after the object and / or the object is placed within the eyelet or the hook. A locking lug, which is formed in particular at the end of a hook, secures an object suspended therein and / or an object suspended or placed therein against slipping out or loosening from the hooking.

In particular, the terminal arms are widened or wider and / or thicker than the prior art, so that a Area and / or an area or excess material results, which is / is suitable for receiving various functional elements. For example, openings and / or recesses may be arranged within the functional area, which are configured either to accommodate additional devices for performing a function or even as a functional element. In addition, due to the wider and / or thicker configuration, the functional area has increased stability. It is advantageous to form the functional area with a minimum width of 2 cm each.

An advantageous embodiment of the multi-purpose clamp has a clamping recess which is arranged proximal to the crossover region and / or as a functional element within the functional region. In particular, the clamping recess comprises two recesses which are complementary to one another on the first clamping arm and the second clamping arm and which are designed to be axially symmetrical with one another and which are movable away from one another or towards each other by opening or closing the clamp. In a particularly advantageous embodiment, the clamping recess on a corrugation and / or grooving. The clamping recess is suitable, for example, for opening and / or closing screw caps on hose connections of transfer devices. Such screw caps often have a similar corrugation and / or grooving, so that a mutual, positive engagement between the clamping recess and screw cap is possible.

Optionally, at least one clamping arm of the multipurpose clamp has at least one lever opening. The lever opening is suitable for applying a leverage to various objects and / or objects. Advantageously, the at least one lever opening is arranged distal to the handle end or proximally to the clamping end and / or as a functional element within the functional area. In particular, the lever opening for applying the leverage force is slipped over an object and / or an object, so that the object and / or the object passes through the lever opening. By tilting the multipurpose clamp or turning it around a transverse axis of the multipurpose clamp passing through the lever opening, a leverage will be exerted on the object and / or object, the amount of which depends on the length of the handle end and additionally the length of the handle extension.

In a further optional embodiment of the invention, the at least one lever opening is formed with a radius which lies in a range between 2.5 mm and 10 mm. For example, the radius or the diameter of a circular lever opening is adapted to the diameter of an ampoule, in particular a crushing ampule, so that the multipurpose clamp is suitable as an ampoule opener. For this purpose, the lever opening is slipped over the upper end of the ampoule. Subsequently, the multi-purpose clamp can be used in the manner of a bottle opener to pry the ampoule.

Advantageously, the multi-purpose clamp or at least the first and the second clamp arm can be produced by injection molding. For this purpose, the multi-purpose clamp can comprise an injection-moldable material, in particular polyamide with a proportion of glass fibers. For example, the known under the name PA6 / G15 polyamide with a glass fiber content of 15%. This material has high mechanical properties, in particular high strength values with low weight and is suitable for processing by injection molding

Due to the high loads that can occur due to the way in which the multipurpose clamp is used, it is advantageous that the minimum load capacity is in a range between 10 kg and 15 kg. By a suitable choice of the material, for example PA6 / G15, but also the geometry, such a minimum load capacity with regard to flexural strength, tensile strength, compressive strength, etc. can be obtained. With regard to the geometry, it is advantageous that the height or thickness of the multi-purpose clamp is at least 8 mm.
