Description

Connection system for fluid connections in medicine

The present invention relates to a connection system for fluid connections, as they are used in particular in medicine and medical technology.

Connection systems for fluid connections are known in the prior art and are used in particular in medicine and medical technology. Here, the connection systems are used in particular in the infusion area, the field of artificial nutrition, in syringes and injection devices, in transfusion and in particular for the supply or transfer of various flow media and as so-called "injection equipment" for the medical and pharmaceutical equipment, which consist inter alia of several components.

In medicine, the absolute safety in the operation of syringes,

Infusion tubes, cannulas etc. top priority. Therefore, in the

Medical technology, the Luer or Luer-Lock principle prevailed over previously common connection systems.

Luer-Lock is a standardized connection system for cannulas, syringes and infusion tubes in the medical field.

The seal is achieved here by a conical construction of the connecting parts, the so-called Luer cone. The inner cone of the one

Connecting side also called "female", the outer cone of the opposite side as "male". The cone has a slope of 6%. When the cone to secure or lock the connection against

accidental release is extended by a thread with union nut, called the system as Luer-Lock. The simpler version without

Screw thread at the spray nozzle is called Luer-approach, Luer-Steck or "Luer Slip".

The Luer-Lock system guarantees compatibility between different

Manufacturers and is internationally recognized. Worldwide, the Luer-Lock connection has become established for reversible connections of syringes, cannulas, infusion tubes, spinal needles and the like. This represents a major advantage, especially in the context of international aid and disaster relief.

At the same time, the system's universality also has its dramatic drawbacks and associated dangers. The Luer-Lock connection holds thereby

dangerous interchangeable possibilities, as it is compatible with vascular (veins and arteries) and spinal or peridural (spinal cord) applications, in part also for enteral (eg nutritional systems and applications) and respiratory (respiratory) applications. Thus, the connection technology does not prevent in principle that z. B. a venous drug to be injected

mistakenly spinal (in the spinal fluid) is applied. Unfortunately, there are several cases of such confusion with fatal outcome. In addition, known in the art fluid-flow

Connection systems also have the disadvantage that they are made, inter alia, from plastics, in their processing plasticizers, such as

Bisphenol-A can be used. When using the fluid flowed through

However, fluid systems can not be excluded that parts of the

Softeners are delivered to the liquid, it being known that these plasticizer materials can lead to a burden on physical health. Among other things, these plasticizers are attributed to effects on hormone balance or carcinogenic effects.

A further disadvantage of the fluid connections known in the prior art is that they are sometimes placed more or less openly in use, so that these, in particular when the patient no liquid is applied, with the air in the treatment room or even in contact with other objects and People get contaminated, for example, with germs.

This contamination can potentially lead to serious infections in the person being treated.

The exemplary embodiment according to FIG. 1 shows a lockable connection system according to the invention consisting of a female 11 and a male 12 connection element with corresponding fixing sections. The female

Connecting element 11 represents a lockable inner cone, which has a fixing section in the form of two wings 13, 13 'on the outside. Of the

Internal cone has a slope of 6%. The distance A denotes the radial outer edge, D, however, the axial thickness of the wings. The male Connecting element 12 represents a lockable outer cone. The slope of the cone is 6%. The male connector has a

Fixing section 14 which is formed in the form of a sleeve with an internal thread 15. The conical connecting elements, consisting of the inner cone and the outer cone correspond to the Luer standard for connection system.

By rectified variation of the fixing sections of the female and the male connecting element are matched, and thus

Confusion exclusion Fixierabschnitte - similar to the key-lock principle - trained. Is the executed as a sleeve with internal thread

Fixing section movably mounted on the corresponding connecting element, this allows an unfixed (unlocked) connection on the Luer standard based fluid-flow component. This can be done analogously by a fixed, i. immovable arrangement of the fixing can be prevented. By such an embodiment, the connection of connecting elements with

Different fixing can be prevented.

In addition, as is also the subject of the invention, that the sleeve of the fixing section is arranged movably to the male plug element or to the female exception section, in particular that this sleeve is independent of the male plug element or to the female exception section rotatable about this. As a result of this arrangement of the sleeve, the fixing sections can be firmly connected to one another without the male plug element or the female exception section having to be moved and / or changed in their position. This arrangement of the sleeve is particularly advantageous if two components are to be connected to the connection system, which itself can not or should not be moved or must be connected to each other in a certain position.

A variation of the fixing elements in the sense of the present invention can relate to both the number and the shape of the wings (shown in FIG. 2 and FIG. 3). These changes imply a simultaneous change of

corresponding, designed in the form of a sleeve with internal thread or bayonet fixing section. This can relate to the number of threads, as well as the shape of the thread on the one hand. Of course, the simultaneous change of number and shape of the wings, with appropriate adaptation of the corresponding formed as a sleeve fixing section variation in the context of the present invention.

Plug element at the end of the portion with the higher slope 168 toward the base of the cone is between 5.8 mm and 6.4 mm, preferably between 6.0 mm and 6.2 mm, more preferably 6.1 mm. Deviations in the fit of the corresponding female receiving section can also be compensated for by means of this design of the male plug element, since the cone area with the larger pitch angle 168 and the

outer diameter end of the range with the higher pitch angle 168 a sealing area is generated.

designed male, Röhr- or cone-shaped plug element 152 is arranged. The outer fixing portion 140, 150 is elongated and has a thread-free, sleeve-shaped extension 155. This serves on the one hand the protection of the male plug element 152 and on the other hand as Führungshiife during assembly.

In summary, rectified variation of the two elements of the connection system ensures a secure, non-intrusive connection of various components to the multiway tap. So can by the

Selection of appropriate components to the respective requirements appropriate overall system can be made available. An example of this arises in the field of artificial nutrition. Due to the high viscosity of the media to be conductive, there are special requirements for the large one of the passage openings or the line system in it

Entity, but also to the pressure resistance of the individual components of the system, such as when using a multi-way tap.
